Technical Field

[0002] The present application relates to the field of vehicle technology, and in particular to a vehicle control system, method, and electronic equipment. Background Art

[0003] With the development of society, vehicles have become an indispensable means of transportation in people's daily lives. During vehicle use, users can use car keys to control the opening or closing of vehicle doors and the start or shutdown of the engine.

[0004] With technological advancements, car keys are constantly evolving. For example, car keys have evolved from physical keys to digital keys. If a user forgets their physical keys, they can establish a communication connection between their terminal device and the vehicle and control the vehicle using the digital key stored on the terminal device. However, if a vehicle only supports connecting to one Bluetooth device, other devices that haven't established a Bluetooth connection with the vehicle cannot connect to it via Bluetooth, and thus cannot control the vehicle using the digital key.

[0005] Summary of the Invention

[0006] The present application provides a vehicle control system, method and electronic device, which enable multiple devices to collaboratively control the vehicle based on a digital car key when the vehicle only supports connection to one Bluetooth device, thereby improving the convenience of multiple devices controlling the vehicle.

[0007] In the first aspect, the present application provides a vehicle control system, characterized in that the system includes a first electronic device, a second electronic device and a first vehicle, the first electronic device and the second electronic device establish a first communication connection, the first electronic device and the first vehicle establish a second communication connection, the second electronic device stores a first digital car key of the first vehicle, and the first electronic device stores a second digital car key of the first vehicle; wherein the second electronic device is used to receive and respond to a first user operation, and send a first control instruction and vehicle information of the first vehicle to the first electronic device through the first communication connection, and the first control instruction is used to instruct the first vehicle to perform a first operation; the first electronic device is used to receive the first control instruction and the vehicle information of the first vehicle, and determine that the second digital car key is stored in the first electronic device based on the vehicle information of the first vehicle; the first electronic device is also used to send the first control instruction to the first vehicle through the second communication connection; the first vehicle is used to receive the first control instruction and perform the first operation based on the first control instruction.

[0008] The first vehicle's vehicle information is used by the first electronic device to determine whether it has also applied for the first vehicle's digital key. Only if both the first and second electronic devices have applied for the first vehicle's digital key can the second electronic device control the first vehicle using the digital key through the first electronic device, thereby improving vehicle control security.

[0009] Optionally, the first control instruction and the vehicle information of the first vehicle may be sent to the first electronic device separately. For example, the second electronic device first sends the vehicle information of the first vehicle to the first electronic device, and then sends the first control instruction to the first electronic device.

[0010] Optionally, in some embodiments, the first control instruction sent by the first electronic device to the first vehicle must conform to a fixed format so that the first vehicle can correctly recognize the first control instruction. Different types of control instructions have different formats. For example, the format of an unlocking control instruction differs from that of a window opening control instruction. Before sending the first control instruction to the first vehicle, the first electronic device may obtain the digital car key vehicle-connected standard, which specifies the formats of different types of control instructions. The first control instruction carries an instruction type. The first electronic device may obtain the first instruction type from the first control instruction. For example, the first instruction type may be an unlocking operation. The first electronic device may then obtain the fixed format of the first instruction type from the digital car key vehicle-connected standard. The first electronic device may then determine whether the format of the first control instruction is the same as the fixed format of the first instruction type. If so, the first electronic device may then send the first control instruction to the first vehicle. If not, the first electronic device may combine the first control instruction with the fixed format of the first instruction type to generate a third control instruction. The third control instruction has the same instruction type as the first instruction type and conforms to the fixed format of the first instruction type. The third control instruction is also used to perform the first operation. The first electronic device then sends the third control instruction to the first vehicle, so that the first vehicle can correctly identify the third control instruction and perform the first operation based on the third control instruction.

[0011] Optionally, in some embodiments, the first control instruction also carries a version number. The first electronic device can verify the legitimacy of the first control instruction based on the version number carried by the first control instruction. Specifically, the first electronic device can obtain the version number of the fourth vehicle control instruction in the first electronic device based on the first instruction type in the first control instruction. The fourth vehicle control instruction has the same vehicle control operation type as the first vehicle control instruction, for example, the fourth vehicle control instruction and the first vehicle control instruction are both unlocking operations. In the case that the fourth vehicle control instruction version number is the same as the first vehicle control instruction version number, the first control instruction is legal, and the first electronic device can send the first control instruction to the first vehicle. If the fourth vehicle control instruction version number is different from the first vehicle control instruction version number, the first control instruction is illegal, and the first electronic device will not send the first control instruction to the first vehicle.

[0012] Through this method, when the vehicle only supports connecting to one Bluetooth device, multiple devices can collaboratively control the vehicle based on the digital car key, thereby improving the convenience of multiple devices controlling the vehicle.

[0013] In combination with the first aspect, in a possible implementation, the first electronic device is further configured to determine that the first digital car key and the second digital car key are of the same key type.

[0014] In one possible implementation, the second electronic device is further used to send key information of the first digital car key to the first electronic device; the first electronic device is further used to determine that the key types of the first digital car key and the second digital car key are the same based on the key information of the first digital car key and the key information of the second digital car key.

[0015] The first electronic device can determine the key information of the second digital vehicle key based on the vehicle information of the first vehicle. The first electronic device then determines whether the first and second digital vehicle keys are of the same key type based on the key information of the first and second digital vehicle keys. Only if the first and second digital vehicle keys are of the same key type can the second electronic device control the first vehicle using the digital vehicle key through the first electronic device, thereby improving vehicle control security.

[0016] In combination with the first aspect, in one possible implementation, the first electronic device is specifically used to: encrypt the first control instruction based on the second digital vehicle key to obtain an encrypted first control instruction; send the encrypted first control instruction to the first vehicle through a second communication connection; the first vehicle is specifically used to: receive the encrypted first control instruction; decrypt the encrypted first control instruction based on the second digital vehicle key to obtain the first control instruction, and perform a first operation based on the first control instruction.

[0017] Optionally, the first electronic device is also used to send the device information of the first electronic device to the first vehicle, so that the first vehicle can obtain the second digital car key based on the device information of the first electronic device, and decrypt the encrypted first control instruction based on the second digital car key to obtain the first control instruction, and then execute the first operation based on the first control instruction.

[0018] In this way, if the first electronic device determines that both the first electronic device and the second electronic device have applied for the digital vehicle key of the first vehicle, the first electronic device can encrypt the first control instruction based on the second digital vehicle key to obtain the encrypted first control instruction, and then send the encrypted first control instruction to the second electronic device. On the one hand, this improves the security of the control instruction transmission between the device and the vehicle. On the other hand, it also improves the security of the device to the vehicle.

[0019] In combination with the first aspect, in a possible implementation, a first user account is logged in to the first electronic device, and a second user account is logged in to the first electronic device, and the first user account and the second user account are the same or associated with each other.

[0020] In this way, if the user account logged into the first and second electronic devices is the same, the first and second electronic devices can be considered multiple devices of the same user, and a trusted connection can be established between the multiple devices of the same user. For example, the second electronic device can be a watch or bracelet of the first user, and the first electronic device can be the first user's mobile phone.

[0021] In some embodiments, if the user accounts logged into the first and second electronic devices are different, but the first and second user accounts are associated with each other, the first and second electronic devices can be considered multiple devices in a family group, and multiple devices in a family group can also be a trusted connection. The first and second electronic devices can be multiple devices of the same user or multiple devices of different users.

[0022] In this way, only trusted devices can collaborate to control the first vehicle based on the digital car key, thereby improving the security of vehicle control.

[0023] In one possible implementation, the second electronic device is further configured to display a QR code; the first electronic device is further configured to scan the QR code via a camera to establish a trusted connection with the second electronic device. In this way, if the second electronic device is unable to log in to the user account, the first and second electronic devices can establish a trusted connection by scanning the QR code. The first and second electronic devices can be multiple devices of the same user or multiple devices of different users. For example, the second electronic device can be a watch or a bracelet, and the first electronic device can be a mobile phone.

[0024] In this way, only trusted devices can collaborate to control the first vehicle based on the digital car key, thereby improving the security of vehicle control.

[0025] In combination with the first aspect, in one possible implementation, the first electronic device is further used to: display a first user interface, in which a first option is displayed; receive and, in response to a second user operation for the first option, send a request to the second electronic device to establish a trusted connection; the second electronic device is further used to: display a first prompt message in response to the request to establish a trusted connection, the first prompt message being used to prompt the user whether to establish a trusted connection with the first electronic device; receive an input operation from the user for the second option in the first prompt message, and send a message to the first electronic device confirming the establishment of a trusted connection; the first electronic device is further used to: establish a trusted connection with the second electronic device in response to the message confirming the establishment of a trusted connection.

[0026] For example, the first electronic device and the second electronic device can be multiple devices owned by different users. Thus, if a trusted connection between the first electronic device and the second electronic device has not yet been established based on a user account or QR code, the first electronic device and the second electronic device can establish a trusted relationship through active sharing. Devices of different users can establish a trusted connection in this manner, enabling devices of different users to collaboratively control the first vehicle using a digital vehicle key.

[0027] In some embodiments, the user accounts logged into the first electronic device and the second electronic device are different, but the first user account and the second user account are associated with each other. It can also be determined that the relationship between the two devices is untrusted, and the two devices still need to establish a trusted connection by actively establishing a trusted relationship.

[0028] In conjunction with the first aspect, in one possible implementation, the first electronic device is specifically configured to, in response to a message confirming establishment of an association relationship, generate a first random number and send the first random number to the second electronic device; the second electronic device is further configured to, in response to receiving the first random number sent by the first electronic device, generate a second random number and send the second random number to the first electronic device; and generate a first trusted credential based on the first random number and the second random number. The first electronic device is specifically configured to generate a second trusted credential based on the first random number and the second random number.

[0029] In this way, when the first electronic device and the second electronic device have not established a trusted connection based on a user account or a QR code before, when the first electronic device and the second electronic device establish a trusted relationship through active sharing, the first electronic device and the second electronic device can each generate and save a trusted credential. When the first electronic device and the second electronic device interact subsequently, they can verify whether the two parties are in a trusted connection based on the trusted credentials saved by each.

[0030] In combination with the first aspect, in one possible implementation, the second electronic device is also used to send the first trusted credential to the first electronic device; the first electronic device is specifically used to send the first control instruction to the first vehicle through the second communication connection when the first trusted credential and the second trusted credential meet preset conditions.

[0031] Optionally, when a second electronic device needs to control a first vehicle through a first electronic device using a digital car key, and the first electronic device determines that it is not connected to the first electronic device in a trusted manner, the first electronic device may prompt the user whether to establish a trusted relationship with the first electronic device through active sharing to ensure that the second electronic device can control the first vehicle through the first electronic device using the digital car key. Upon user confirmation, the first and second electronic devices may establish a trusted connection in the manner described above.

[0032] Optionally, the second electronic device is further configured to send device information of the second electronic device to the first electronic device, and the first electronic device can obtain a second trusted credential associated with the second electronic device based on the device information of the second electronic device. If it is determined that the first trusted credential and the second trusted credential meet preset conditions, the first electronic device can determine that the second electronic device is a trusted device and then send the first control instruction to the first vehicle via the second communication connection, thereby improving the security of the device to the vehicle.

[0033] In combination with the first aspect, in one possible implementation, the first electronic device is further used to delete the second trusted credential after the storage time of the second trusted credential exceeds the first time; the second electronic device is further used to delete the first trusted credential after the storage time of the first trusted credential exceeds the first time.

[0034] In this way, the trusted credentials stored in the electronic device have a certain time limit. After the first time period has expired, the first electronic device and the second electronic device can delete the trusted credentials stored therein, thereby improving the credibility of the trusted connection between the first electronic device and the second electronic device.

[0035] In conjunction with the first aspect, in one possible implementation, the system further includes a third electronic device, in which a third digital vehicle key of the first vehicle is stored; the first vehicle is further configured to send a broadcast, where the broadcast is used for other devices to discover the first vehicle; the third electronic device is further configured to: receive and respond to a third user operation, where the third user operation is used to control the first vehicle to perform a second operation; receive and respond to the broadcast sent by the first vehicle to send a request to establish a third communication connection to the vehicle; the first vehicle is further configured to send a request to disconnect the second communication connection to the first electronic device in response to the third communication connection request;

[0036] The first electronic device is further used to receive a fourth user operation to disconnect the second communication connection with the first vehicle; the first vehicle is further used to establish a third communication connection with a third electronic device; the third electronic device is further used to send the second control instruction to the first vehicle through the third communication connection; the first vehicle is further used to receive the second control instruction and perform a second operation based on the second control instruction.

[0037] In this way, when the vehicle only supports connecting to one Bluetooth device, for example, the first vehicle is connected to the first electronic device, when the second electronic device needs to control the first vehicle, the second electronic device can actively initiate a connection request to the first vehicle, and the first vehicle can disconnect the communication connection with the first electronic device and establish a communication connection with the second electronic device, so that the second electronic device can directly control the first vehicle through the first digital car key.

[0038] Optionally, in the present application, when the first vehicle is connected to the first electronic device, the first vehicle can still send a broadcast so that other devices can obtain the address of the first vehicle based on the broadcast and establish a communication connection with the first vehicle.

[0039] In other embodiments, when the first vehicle is connected to the first electronic device, the first vehicle may not send a broadcast. When the second electronic device applies for a digital car key, the first vehicle may send the address of the first vehicle to the second electronic device, so that when the second electronic device needs to control the first vehicle, the second electronic device can actively initiate a communication connection with the first vehicle based on the saved address of the first vehicle.

[0040] In combination with the first aspect, in one possible implementation, the first electronic device is further used to display a second prompt message in response to a request to disconnect the second communication connection, and the second prompt message is used to prompt the user whether to disconnect the second communication connection with the first vehicle; the first electronic device is specifically used to receive and respond to a fourth user operation for the second option in the second prompt message to disconnect the second communication connection with the first vehicle.

[0041] In this way, the first electronic device can disconnect the communication connection with the first vehicle only after receiving the disconnection operation from the user.

[0042] In combination with the first aspect, in one possible implementation, the first vehicle is further used to send a first message to the first electronic device through a second communication connection after executing the first control instruction; the first electronic device is further used to send the first message to the second electronic device through the first communication connection; the second electronic device is further used to display a third prompt message in response to the first message, and the third prompt message is used to prompt the user that the second electronic device has controlled the first vehicle to perform the first operation through the first electronic device.

[0043] In this way, after the second electronic device controls the first vehicle through the first electronic device, the second electronic device may display a prompt message to remind the user that the second electronic device controls the first vehicle through the first electronic device.

[0044] In conjunction with the first aspect, in one possible implementation, the first electronic device is further configured to send a second message to the second electronic device via the first communication connection if the second digital vehicle key stored in the first electronic device is not determined based on the vehicle information of the first vehicle, and / or the first digital vehicle key and the second digital vehicle key are of different key types; and the second electronic device is further configured to display a fourth prompt message in response to the second message, the fourth prompt message being configured to prompt a user that the first electronic device is currently unable to control the first vehicle to perform the first operation. In this way, if the vehicle cannot be controlled, the second electronic device may also display a prompt message to prompt the user that the first vehicle cannot be controlled.

[0045] In combination with the first aspect, in one possible implementation, the key information of the first digital car key includes any one or more of the following: key type, key identification; the vehicle information of the first vehicle includes any one or more of the following: vehicle identification code, vehicle model, vehicle manufacturer, vehicle production date, vehicle engine model, and vehicle license plate number.

[0109] In some embodiments, the electronic device 200 may be a watch, the electronic device 300 may be a mobile phone, and the electronic device 200 and the electronic device 300 may be multiple devices of the same user.

[0110] In other embodiments, the electronic device 200 and the electronic device 300 may both be mobile phones, and the electronic device 200 and the electronic device 300 may be devices of different users.

[0111] After electronic device 200 and electronic device 300 establish a trusted relationship, electronic device 300 can send control instructions to vehicle 100 through electronic device 200. Specifically, electronic device 200 and vehicle 100 establish a Bluetooth connection, and electronic device 300 and electronic device 200 establish a communication connection. This application does not limit the order of the steps for establishing the Bluetooth connection between electronic device 200 and vehicle 100, nor the order of the steps for establishing the communication connection between electronic device 300 and electronic device 200. A user can operate within a first application on electronic device 300 to control vehicle 100 using the digital car key. Specifically, in response to user operation, if electronic device 200 and electronic device 300 are trusted devices and both electronic device 200 and electronic device 300 have applied for the digital car key of vehicle 100, electronic device 300 can send a first control instruction to electronic device 200, which then transmits the first control instruction to vehicle 100 via the Bluetooth connection between electronic device 200 and vehicle 100. Vehicle 100 receives and responds to the first control instruction, executing the first control instruction.

[0112] The communication system 10 is not limited to the vehicle 100 , the electronic device 200 , and the electronic device 300 shown in FIG. 1 , and may include more or fewer devices.

[0117] Electronic device 200 establishes a Bluetooth connection with vehicle 100. After vehicle 100 and electronic device 200 establish a Bluetooth connection, vehicle 100 continues to periodically / irregularly send Bluetooth broadcasts. Other electronic devices near vehicle 100 can receive the Bluetooth broadcasts sent by vehicle 100. For example, electronic device 300 receives and responds to the Bluetooth broadcast sent by vehicle 100 and sends a Bluetooth connection establishment request to vehicle 100.

[0118] In response to the Bluetooth connection establishment request, the vehicle 100 sends a Bluetooth disconnection request to the electronic device 200.

After the vehicle 100 disconnects the Bluetooth connection with the electronic device 200, the vehicle 100 can establish a Bluetooth connection with the electronic device 300.

[0119] After establishing a Bluetooth connection between vehicle 100 and electronic device 300, the user can operate within the first application on electronic device 300 to issue a first control command to vehicle 100. If electronic device 300 has applied for the digital key for vehicle 100, electronic device 300 can send the first control command to vehicle 100 via the Bluetooth connection between electronic device 300 and vehicle 100. Vehicle 100 receives and responds to the first control command, executing the first control command.

In the embodiments of the present application, the CAN bus 11 can be used to transmit data involved in a vehicle safety communication method between various components. The specific implementation of this method can be found in the detailed description of the method embodiment below.

[0171] The various components of the vehicle 100 may be connected and communicated via other methods, not limited to the CAN bus 11. In other embodiments, the various components of the vehicle 100 may also communicate via other methods. For example, the various components may communicate via an in-vehicle Ethernet (Ethernet), a local interconnect network (LIN) bus, FlexRay, or a common in-vehicle media-oriented system (MOST) bus, etc., although this is not a limitation in the present embodiment. The following embodiments are described using the assumption that the various components communicate via the CAN bus 11.

[0177] T-box 14 is mainly responsible for communicating with the Internet, providing a remote communication interface for vehicle 100, and providing services including navigation, entertainment, driving data collection, driving route recording, vehicle fault monitoring, vehicle remote query and control (such as unlocking and closing, air conditioning control, window control, engine torque limit, engine start and stop, seat adjustment, query of battery power, fuel level, door status, etc.), driving behavior analysis, wireless hotspot sharing, roadside assistance, abnormal reminders, etc.

[0178] The T-box 14 can be used to communicate with a telematics service provider (TSP) and a user (e.g., driver)-side electronic device (e.g., electronic device 200) to display and control the vehicle status on the electronic device 200. When the user sends a control command through the vehicle management application on the electronic device 200, the TSP will issue a request instruction to the T-box 14. After receiving the control command, the T-box 14 sends a control message through the CAN bus to control the vehicle 100, and finally feeds back the operation results to the vehicle management application on the user-side electronic device 200. In other words, the data read by the T-box 14 through the CAN bus 11, such as vehicle condition reports, driving reports, fuel consumption statistics, violation inquiries, location, driving behavior, etc., can be transmitted to the TSP backend system via the network, and then forwarded by the TSP backend system to the user-side electronic device 200 for the user to view.

[0179] The T-box 14 may specifically include a communication module and a display screen.

[0180] Among them, the communication module can be used to provide wireless communication functions, supporting the vehicle 100 to communicate with other devices through wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared technology (IR), ultra-wideband (UWB) and other wireless communication technologies. The communication module can also be used to provide mobile communication functions, supporting the vehicle 100 to communicate with other devices through communication technologies such as global system for mobile communications (GSM), universal mobile telecommunications system (UMTS), wideband code division multiple access (WCDMA), time-division code division multiple access (TD-SCDMA), long term evolution (LTE), 5G and the future 6G.

[0181] The communication module can establish connections and communicate with other devices such as servers and user-side electronic devices through cellular V2X (vehicle to everything) communication technology (C-V2X) based on cellular networks. C-V2X can include, for example, long-term evolution (LTE)-based V2X (LTE-V2X) and 5G-V2X.

[0182] In the embodiment of the present application, the communication module may be used to negotiate a key with the electronic device 200, or to notify the electronic device 200 of a key determined by the vehicle 100, or to receive a key determined by the electronic device 200.

The user interface displayed on the display screen in the vehicle 100 can be specifically described in detail in the subsequent embodiments and will not be described here.

[0185] T-box 14 may also be referred to as a vehicle system, a telematics processor, a vehicle gateway, etc., which is not limited in the embodiments of the present application.

[0186] The transmission ECU 123 is used to manage the transmission.

[0187] The transmission 15 is a mechanism used to change the engine's speed and torque. It can change the output-to-input ratio in a fixed or step-by-step manner. Transmission 15 components may include a transmission mechanism, an operating mechanism, and a power take-off mechanism. The transmission mechanism primarily changes the magnitude and direction of torque and speed; the operating mechanism primarily controls the transmission mechanism to achieve gear shifting, thereby changing the transmission ratio and achieving speed and torque variations.

[0188] The drive recorder ECU 124 is used to manage the drive recorder 16 .

[0189] The components of the driving recorder 16 may include a host computer, a vehicle speed sensor, and data analysis software. The driving recorder 16 is a device that records images and sounds of a vehicle while it is in motion, including relevant information such as driving time, speed, and location. In this embodiment of the present application, while the vehicle is in motion, the vehicle speed sensor collects wheel speed information and transmits it to the driving recorder 16 via the CAN bus.

[0190] The ABS ECU 125 is used to manage the ABS 17 .

[0191] ABS17 automatically controls the braking force during vehicle braking to prevent the wheels from locking and maintain a rolling and sliding state, thereby ensuring maximum adhesion between the wheels and the ground. During braking, if the electronic control unit determines that a wheel is approaching locking based on the wheel speed signal input by the wheel speed sensor, the ABS will enter the anti-lock brake pressure adjustment process.

[0192] Sensor system 18 may include: acceleration sensors, vehicle speed sensors, vibration sensors, gyroscope sensors, radar sensors, signal transmitters, signal receivers, etc. Acceleration sensors and vehicle speed sensors are used to detect the speed of vehicle 100. Vibration sensors can be installed under the seat, on the seat belt, on the seat back, on the operating panel, on the airbag, or in other locations to detect whether vehicle 100 has been hit and the user's location. Gyroscope sensors can be used to determine the motion posture of vehicle 100. Radar sensors may include laser radar, ultrasonic radar, millimeter wave radar, etc. Radar sensors, signal transmitters, and signal receivers can be used to detect the user's location.

[0193] The camera system 19 may include multiple cameras for capturing still images or videos. The cameras in the camera system 19 may be located in front of, behind, on the sides of, or inside the vehicle, to facilitate functions such as assisted driving, driving recording, panoramic surround view, and in-vehicle monitoring.

[0194] The sensor system 18 and the camera system 19 can be used to detect the surrounding environment, so that the vehicle 100 can make corresponding decisions to cope with environmental changes. For example, they can be used to complete the task of paying attention to the surrounding environment during the autonomous driving stage.

[0195] The microphone 20, also known as a "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or outputting a voice command, the user can speak by putting their mouth close to the microphone 20 to input the sound signal into the microphone 20. The vehicle 100 can be provided with at least one microphone 20. In other embodiments, the vehicle 100 can be provided with two microphones 20, which can not only collect sound signals but also realize noise reduction. In other embodiments, the vehicle 100 can also be provided with three, four or more microphones 20 to form a microphone array to collect sound signals, reduce noise, identify the sound source, realize directional recording functions, etc.

[0196] In addition, the vehicle 100 may also include multiple interfaces, such as a USB interface, an RS-232 interface, an RS485 interface, etc., which can be connected to an external camera, a microphone, headphones, and an electronic device 200 on the user side.

[0197] It should be understood that the illustrated structures of the embodiments of this application do not constitute specific limitations on the vehicle system. Vehicle 100 may include more or fewer components than shown, or may combine or separate certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0198] FIG6 shows a schematic diagram of the software structure of a vehicle 100 .

[0199] As shown in FIG6 , the vehicle 100 may include but is not limited to: a communication module, a control module, an authentication module, and a digital vehicle key management module.

[0200] The communication module can be used for the vehicle 100 to communicate with other devices. For example, the vehicle 100 can communicate with the electronic device 300 and the electronic device 200 through the communication module. For example, the communication module can be a Bluetooth communication module, and the vehicle 100 can establish Bluetooth connections with the electronic device 200 and the electronic device 300, and communicate with the electronic device 200 and the electronic device 300 respectively based on the Bluetooth connections.

[0201] The control module can be used to control the vehicle 100. For example, it can control the vehicle 100 to open / close the locks, open / close the trunk, open / close the windows, start / stop the engine, etc.

[0202] The authentication module can be used to implement security verification functions between the vehicle 100 and other devices, including key management, authentication control and other functions.

[0203] The digital car key management module can be used to store, load, and use the digital car key of the vehicle 100. For example, the digital car key management module can store the digital car key of the vehicle 100 in the security chip of the vehicle 100 to prevent the digital car key of the vehicle 100 stored in the vehicle 100 from being leaked.

[0204] Next, the electronic device applying for the digital car key of the vehicle 100 and the electronic device controlling the vehicle 100 based on the digital car key of the vehicle 100 will be described in detail.

[0205] First, it is introduced how the electronic device applies for the digital car key of the vehicle 100.

[0206] The user can apply for the digital car key of the vehicle 100 in the first application, the user can also apply for the digital car key of the vehicle 100 in the second application, or the user can apply for the digital car key of the vehicle 100 on the vehicle.

[0207] The second application establishes a binding relationship with the vehicle 100 , and the vehicle information of the vehicle 100 is stored in the second application.

[0208] 7A-7L are schematic diagrams showing a user applying for a digital car key for a vehicle 100 within a first application.

[0209] In Figures 7A to 7L, the first application needs to obtain the vehicle information of the vehicle 100 from the second application, and then apply for the digital car key of the vehicle 100 based on the vehicle information of the vehicle 100.

[0210] FIG7A shows a main interface 710 of the electronic device 200. The main interface 710 includes multiple application icons, such as a weather application icon, a Honor Store application icon, a smart home application icon, a sports and health application icon, a memo application icon, a calendar application icon, a second application icon, a first application icon, a camera application icon, a contact application icon, a phone application icon, and a message application icon, etc. The main interface 710 also displays a battery indicator, a weather indicator, a date indicator, a network signal indicator, a page indicator, etc.

[0211] In some embodiments, the second application may be referred to as a vehicle owner application.

[0212] As shown in Figure 7A, electronic device 200 may receive a user input operation (e.g., a single click) on the icon of the first application. In response to the user input operation, electronic device 200 may display user interface 720 shown in Figure 7B. User interface 720 is the main interface of the first application.

[0213] As shown in FIG7B , the user interface 720 displays multiple options, such as payment options, ride options, door opening options, card wallet options, key options, transportation options, discount gas options, my bill options, life information options, etc. Different options may correspond to different functional features.

[0214] For example, as shown in FIG7B , the electronic device 200 may receive a user input operation (eg, a single click) for a key option in the user interface 720 . In response to the user input operation, the electronic device 200 may display the user interface 730 shown in FIG7C .

[0215] As shown in Figure 7C, user interface 730 displays multiple key options and a "My Keys" option. The multiple key options may include, for example, an access card option, a car key option, a door lock key option, a luggage key option, and so on. Users can set digital keys for different objects in user interface 730. For example, a user can use the access card option to set a digital key for a door. A user can use the car key option to set a digital key for a vehicle. A user can use the door lock key option to set a digital key for a door lock. A user can use the luggage key option to set a digital key for a luggage. The user can use the "My Keys" option to view the digital keys for different objects that the user has set.

[0216] For example, as shown in FIG7C , the electronic device 200 may receive a user input operation (eg, a single click) for the My Keys option in the user interface 730 . In response to the user input operation, the electronic device 200 may display the user interface 740 shown in FIG7D .

[0217] As shown in FIG7D , the user has not set a digital key yet. The user can add digital keys for different objects through the add option in the user interface 740 .

[0218] For example, as shown in FIG7D , the electronic device 200 may receive a user input operation (e.g., a single click) for adding an option in the user interface 740. In response to the user input operation, the electronic device 200 may display the user interface 750 shown in FIG7E . The user interface 750 includes digital key setting options for multiple objects, such as digital key setting options for doors, digital key setting options for vehicles, digital key setting options for smart door locks, and digital key setting options for luggage.

[0219] As shown in FIG7E , electronic device 200 may receive a user input operation (e.g., a single click) for a digital key setting option for a car in user interface 750. In response to the user input operation, electronic device 200 may display user interface 760 shown in FIG7F . User interface 760 shows digital key setting options for cars of different brands, such as AA, BB, CC, DD, EE, FF, and GG.

[0220] As shown in FIG7F , the electronic device 200 may receive a user input operation (e.g., a single click) for the digital key setting option for the AA vehicle in the user interface 760. In response to the user input operation, the electronic device 200 may display the user interface 770 shown in FIG7G . The user interface 770 may include a create digital car key option, through which the user may create a digital car key for the vehicle 100.

[0221] Before the first application in the electronic device 200 obtains the digital key of the vehicle 100, it needs to obtain the vehicle information of the vehicle 100 and obtain the digital key of the vehicle 100 based on the vehicle information of the vehicle 100. The vehicle information of the vehicle 100 includes, but is not limited to, one or more of the following: vehicle identification number (or vehicle ID), vehicle model, vehicle license plate number, vehicle manufacturer, vehicle production date, vehicle engine model, etc.

[0222] For example, as shown in FIG7G , the electronic device 200 may receive a user input operation (e.g., a single click) for the option to create a digital car key in the user interface 770. In response to the user input operation, the electronic device 200 may display the user interface 7710 shown in FIG7H . The user interface 7710 displays a prompt message “Loading” to prompt the user that the electronic device 200 is acquiring the digital car key of the vehicle 100.

[0223] In one embodiment, the first application can jump to the interface of the second application. For example, the electronic device 200 can display the user interface 780 shown in Figure 7I, and the user interface 780 can be the main interface of the second application. The user interface 780 can include the driving information of the vehicle 100. The name of the vehicle 100 can be "AA M7". For example, the driving information of the vehicle 100 can include a total mileage of 1100km, the remaining power of the vehicle 100 can still travel 200km, and the remaining fuel of the vehicle 100 can still travel 900km. The user interface 780 also shows multiple options, such as the option to create an activation code and the option to add a digital car key to the wallet.

[0224] For example, as shown in Figure 7I, the electronic device 200 can receive a user input operation (such as a single click) to add a digital car key to the wallet. In response to the user's input operation, the second application can send the vehicle information of the vehicle 100 to the first application, and the first application in the electronic device 200 can obtain the vehicle information of the vehicle 100.

[0225] Optionally, in response to the user's input operation to add the digital car key to the wallet, the electronic device 200 may display the prompt message "Applying for the digital car key for the vehicle M7, please wait" as shown in FIG7J to remind the user that the digital car key for the vehicle 100 is being applied for. The electronic device 200 may also not display the prompt message shown in FIG7J , and this application is not limited thereto.

[0226] In other embodiments, after the electronic device 200 displays the user interface 780 shown in FIG. 7I , the electronic device 200 may not receive the user's input operation to add the digital car key to the wallet, and the electronic device 200 may obtain the vehicle information of the vehicle 100 from the second application. The electronic device 200 then jumps to the first application and displays the prompt information shown in FIG. 7J , allowing the first application to obtain the vehicle information of the vehicle 100.

[0227] In other embodiments, the first application may not jump to the interface of the second application. The first application may be integrated with a software development kit (SDK) for storing and obtaining vehicle information in the second application, and the first application may obtain the vehicle information of the vehicle 100 stored in the second application through the SDK of the second application.

[0228] After the first application obtains the vehicle information of vehicle 100, electronic device 200 can send the vehicle information of vehicle 100 and the device information of electronic device 200 to the first application server through the first application. The first application server then sends the vehicle information of vehicle 100 to the vehicle server. After receiving the vehicle information of vehicle 100 sent by the first application server, the vehicle server can generate a second digital vehicle key for vehicle 100 and bind and store the device information of electronic device 200 with the second digital vehicle key.

[0229] After generating the second digital car key, the vehicle server sends the second digital car key to the first application server, and the first application server then sends the second digital car key to the first application.

[0230] After the first application obtains the second digital car key, the first application can display the user interface 790 shown in Figure 7K. A card 7401 is displayed in the user interface 790, and the vehicle logo "Wenjie M7" is displayed on the card 7401 to prompt the user that the card 7401 is the card corresponding to the second digital car key of the vehicle 100. A plurality of control options are also shown on the card 7401, such as a car lock open / close option, a trunk open / close option, a window open / close option, an engine open / close option, etc. Only some control options of the vehicle 100 are shown on the card 7401. The electronic device 200 can receive a sliding operation (such as a right or left sliding operation) applied by the user on the card 7401 and display other control options that are not displayed. The user interface 790 also shows an identity authentication option and a credibility authentication option. The user can actively establish a trusted relationship with other devices through the credibility authentication option.

[0231] Optionally, after the first application obtains the second digital car key, the first application may send a message to the second application to indicate that the first application has obtained the digital car key of the vehicle 100. In response to the message sent by the first application, the electronic device 200 may display the user interface 7990 shown in Figure 7L within the second application. The user interface 7990 includes a card 7911, which may include a view option and a delete option. The user can view detailed information about the second digital car key, such as the application time and validity period, by using the view option. The user can delete the second digital car key stored on the electronic device 200 by using the delete option.

[0232] 7M-7P show another schematic diagram of a user applying for a digital car key for a vehicle 100 within a first application.

[0233] In FIG7M-FIG7P , the first application does not need to obtain the vehicle information of the vehicle 100 from the second application. However, it needs to obtain the activation code from the second application, which is used by the first application to apply for the digital car key of the vehicle 100.

[0234] For example, as shown in Figure 7M, the electronic device 200 can receive a user input operation (such as a single click) on the application icon of the second application in the user interface 710. In response to the user input operation, the electronic device 200 can display the user interface 780 shown in Figure 7N, and the user interface 780 can be the main interface of the second application.

[0235] As shown in FIG7N , the electronic device 200 may receive a user input operation for the Create Activation Code option in the user interface 780. In response to the user input operation, in one possible implementation, the second application may send a request for an activation code to the vehicle server. After the vehicle server generates the activation code, the vehicle server sends the activation code to the second application, and the second application may obtain the activation code. In other possible implementations, the second application may randomly generate an activation code and then send the activation code to the vehicle server.

[0236] After the second application obtains the activation code, the electronic device 200 may display a window 7701 as shown in FIG7O . Window 7701 displays the activation code "123456." The user may enter the activation code in the first application, allowing the first application to apply for a digital key for the vehicle 100 based on the activation code.

[0237] Referring to the description in the embodiments of Figures 7A-7D, the electronic device 200 receives and responds to the user's input operation (such as a single click) for adding an option in the user interface 740. In response to the user's input operation, the electronic device 200 can display the window 7702 shown in Figure 7P, and the user can enter the activation code generated by the second application in window 7702.

[0238] After the user enters the activation code generated by the second application in window 7702, the electronic device 200 may receive the user's input operation (e.g., a single click) for the Continue option in window 7701. In response to the user's input operation, the first application may send the device information of the electronic device 200 and the activation code entered by the user to the vehicle server. After the vehicle server receives the device information of the electronic device 200 and the activation code entered by the user sent by the first application, if the activation code entered by the user is the same as the activation code of the vehicle 100 generated by the vehicle server or the activation code of the vehicle 100 generated by the second application, the vehicle server may obtain the vehicle information of the vehicle 100 and generate a second digital vehicle key. The vehicle server then sends the second digital vehicle key and the vehicle information of the vehicle 100 to the first application. The first application may save the second digital vehicle key and the vehicle information of the vehicle 100.

[0239] After the first application obtains the second digital car key, the first application may display the user interface 790 shown in FIG7K. Optionally, the electronic device 200 may also display the user interface 7990 shown in FIG7L within the second application. This application will not be repeated here.

[0240] 7Q-7T show another schematic diagram of a user applying for a digital car key for a vehicle 100 within a first application.

[0241] In the embodiment of Figures 7Q-7T , the first application also does not need to obtain vehicle information of vehicle 100 from the second application. The difference between the embodiment of Figures 7Q-7T and the embodiment of Figures 7M-7P is that in the embodiment of Figures 7Q-7T , the first application obtains the activation code from vehicle 100, while in the embodiment of Figures 7M-7P , the first application obtains the activation code from the second application.

[0242] 7Q exemplarily illustrates a user interface 7910 displayed by vehicle 100. User interface 7910 may be provided by a vehicle management application in vehicle 100. User interface 7910 may be displayed by vehicle 100 in response to a user operation on a vehicle management application icon in the main interface, a user operation on a user avatar in the main interface, or other user operation.

[0243] The user interface 7910 displays: a top status bar, a login avatar 402, a login account 403, a control 404 for switching accounts, a control 405 for logging out, a control 406 for starting face recognition, a control 407 for generating a digital car key for the vehicle 100, user local data management information 408, and a bottom task bar 409.

[0244] The top status bar may include: an avatar corresponding to the user account currently logged in to the vehicle 100, a message notifier, a weather indicator, a time indicator, a battery status indicator, a Bluetooth indicator, one or more signal strength indicators of Wi-Fi signals, one or more signal strength indicators of mobile communication signals (also known as cellular signals), and the like.

[0245] The login avatar 402 is the avatar corresponding to the user account currently logged in to the vehicle 100. A prompt message is also displayed on the login avatar 402 in Figure 7Q, indicating that the current login account is the vehicle owner account.

[0246] The user local data management information 408 is used to display the local user data of the vehicle 100, such as historically logged-in account information, etc., and can also be used to provide an entry for the user to delete part or all of the local user data.

[0247] The bottom task bar 409 may include: a control for entering the main interface, a multi-tasking key, a seat adjustment control, an air conditioning temperature adjustment control, a volume adjustment control, and the like.

[0248] Control 407 is used to monitor user operations (such as touch operations, click operations, etc.), and the vehicle 100 can respond to the user operation and display one or more devices for displaying the currently applied digital car keys.

[0249] For example, as shown in FIG7Q , the vehicle 100 may receive a user input operation (e.g., a click) on the control 407. In response to the user input operation, the vehicle 100 may display the window shown in FIG7R . The window shown in FIG7R displays the number and device identification of devices that have applied for the digital car key of the vehicle 100. The window shown in FIG7R also displays a Create Activation Code option. The user can use this Create Activation Code option to have the vehicle 100 generate an activation code.

[0250] As shown in Figure 7R, the vehicle 100 can receive a user input operation (such as a single click) for the option to create an activation code in the window shown in Figure 7R. In response to the user's input operation, in one possible implementation, the vehicle 100 can send a request for an activation code to the vehicle server. After the vehicle server generates the activation code, the vehicle server sends the activation code to the vehicle 100, and the vehicle 100 can obtain the activation code. In other possible implementations, the vehicle 100 can randomly generate an activation code and then send the activation code to the vehicle server. After the vehicle 100 obtains the activation code, the vehicle 100 can display the window shown in Figure 7S. The window shown in Figure 7S shows the activation code 7913, and the activation code 7913 can be "123953". The window shown in Figure 7S also shows a prompt message "Please open the first application on your phone and enter the activation code."

[0251] In some embodiments, to ensure the security of the digital key of vehicle 100, the activation code 7913 displayed in the window shown in FIG7S has a certain time limit and expires after being displayed for a predetermined period of time. After expiration, vehicle 100 can proactively refresh the activation code and display the refreshed activation code on the display screen. Alternatively, vehicle 100 can notify the user that the current activation code has expired and prompt the user to refresh and obtain a new activation code.

[0252] After the vehicle 100 generates the activation code 7913, the vehicle 100 may send the activation code 7913 to the vehicle server.

[0253] Referring to the description in the embodiments of Figures 7A-7D, the electronic device 200 receives and responds to the user's input operation (such as a single click) for adding an option in the user interface 740. In response to the user's input operation, the electronic device 200 can display the window 7702 shown in Figure 7P, and the user can enter the activation code generated by the vehicle 100 in the window 7702.

[0254] After the user enters the activation code generated by the second application in window 7702, the electronic device 200 may receive the user's input operation (e.g., a click) for the Continue option in window 7701. In response to the user's input operation, the first application may send the device information of the electronic device 200 and the activation code entered by the user to the vehicle server. After the vehicle server receives the device information of the electronic device 200 and the activation code entered by the user sent by the first application, if the activation code entered by the user is the same as the activation code of the vehicle 100 generated by the vehicle server or the activation code of the vehicle 100 generated by the vehicle 100, the vehicle server may obtain the vehicle information of the vehicle 100 and generate a second digital vehicle key. The vehicle server then sends the second digital vehicle key and the vehicle information of the vehicle 100 to the first application. The first application may save the second digital vehicle key and the vehicle information of the vehicle 100.

[0255] After the first application obtains the second digital car key, the first application may display the user interface 790 shown in FIG7K. Optionally, the electronic device 200 may also display the user interface 7990 shown in FIG7L within the second application. This application will not be repeated here.

[0256] Optionally, after the first application in the electronic device 200 obtains the second digital car key, the vehicle server may send a feedback message to the vehicle 100 to inform the vehicle 100 that the first application has obtained the second digital car key. In response to the feedback message sent by the vehicle server, the vehicle 100 may display the prompt message 7914 shown in Figure 7T. The prompt message 7914 may include "Lisa has applied for the digital car key for car AA M7" to prompt the user that the electronic device 200 has successfully applied for the digital car key for the vehicle 100. The electronic device 200 may also not display the prompt message 7914 shown in Figure 7T, and this application does not limit this.

[0257] Alternatively, in other implementations, the user may not enter the activation code 7913 in the first application. Instead, the user may enable the near field communication (NFC) function of the electronic device 200 and place the electronic device 200 close to the NFC sensing area of ​​the vehicle 100. The vehicle 100 may then send the activation code 7913 to the first application in the electronic device 200 via NFC. The vehicle 100 may also send the activation code 7913 to the electronic device 200 via other methods, which are not limited in this application.

[0258] 7U-7W show another schematic diagram of a user applying for a digital car key for a vehicle 100 within a first application.

[0259] In the embodiments of Figures 7U-7W , the first application does not need to obtain the vehicle information of vehicle 100 from the second application, nor does the first application require the user to enter an activation code. The first application can prompt the user to enter their identity information, which is bound to the vehicle information. The first application can then apply for a digital key for vehicle 100 based on the user's identity information entered by the user.

[0260] The user's identity information includes but is not limited to any of the following: mobile phone number, ID number, etc. The embodiment of this application uses the mobile phone number as an example. The user's identity information can also be other information, which is not limited in this application.

[0261] For example, referring to the description in the embodiments of Figures 7A-7D, the electronic device 200 receives and responds to the user's input operation (such as a single click) for adding an option in the user interface 740. In response to the user's input operation, the electronic device 200 can display the window 7904 shown in Figure 7U, and the user can enter the user's mobile phone number in window 7702.

[0262] As shown in Figure 7V, after the user enters the user's mobile phone number "12345678" in window 7702, the electronic device 200 can receive the user's input operation for the continue option in window 7701. In response to the user's input operation, the first application can send the user's mobile phone number to the vehicle server.

[0263] Optionally, after the electronic device 200 receives the user's input operation for the continue option in window 7701, the electronic device 200 may prompt the user to enter the SMS verification code corresponding to the mobile phone number. If the SMS verification code is entered correctly, the first application then sends the user's mobile phone number to the vehicle server.

[0264] Optionally, after the electronic device 200 receives the user's input operation for the Continue option in window 7701, the electronic device 200 can verify the user's identity, including but not limited to: face recognition, fingerprint recognition, and voiceprint recognition. After the identity verification is passed, the first application then sends the user's mobile phone number to the vehicle server.

[0265] After the vehicle server obtains the user's mobile phone number sent by the first application, the vehicle server can determine the vehicle information of one or more vehicles bound to the user's mobile phone number based on the user's mobile phone number.

[0266] When the number of vehicles bound to the user's mobile phone number is one, the vehicle server can obtain the vehicle information of the vehicle (for example, the vehicle information of vehicle 100), the vehicle server generates a second digital car key for vehicle 100, and sends the second digital car key and the vehicle information of vehicle 100 to the first application.

[0267] When there are more than one vehicles bound to the user's mobile phone number, the vehicle server can send the identifications of multiple vehicles to the first application, and the user can select the target vehicle from the multiple vehicles. For example, when the number of vehicles bound to the user's mobile phone number is greater than or equal to 2, the electronic device 200 can display the prompt information 7905 shown in Figure 7W. The prompt information 7905 may include the vehicle identifications of multiple vehicles, such as the vehicle identification of the vehicle "Wenjie M5" and the vehicle identification of the vehicle "Wenjie M7". The user can select a vehicle from multiple vehicles for which a digital car key is currently required. For example, the vehicle identification of vehicle 100 may be "Wenjie M7".

[0268] For example, as shown in FIG7W , the electronic device 200 may receive a user's selection operation for the vehicle identification of "Ask World M7". Subsequently, the electronic device 200 may receive a user's input operation (e.g., a single click) for confirming an option in the prompt information 7905. In response to the user's input operation, the first application may send the vehicle identification of the vehicle 100 to the vehicle server. The vehicle server may obtain the vehicle information of the vehicle 100 based on the vehicle identification of the vehicle 100. The vehicle server may generate a second digital car key for the vehicle 100 and send the second digital car key and the vehicle information of the vehicle 100 to the first application.

[0269] After the first application obtains the second digital car key, the first application may display the user interface 790 shown in FIG7K. Optionally, the electronic device 200 may also display the user interface 7990 shown in FIG7L within the second application. This application will not be repeated here.

[0270] In other embodiments, the user can also operate within the second application to apply for a schematic diagram of the digital car key of the vehicle 100. Referring to the description in the embodiments of Figures 7M-7N, the electronic device 200 can receive the user operation and display the user interface 780 shown in Figure 7N. For example, as shown in Figure 7I, the electronic device 200 can receive the user's input operation (such as a single click) for the option of adding a digital car key to the wallet in the user interface 780. In response to the user's input operation, the second application can obtain the vehicle information of the vehicle 100 and send the vehicle information of the vehicle 100 to the first application. At the same time, the electronic device 200 can jump to display the first application and display the prompt information shown in Figure 7J. After the first application obtains the vehicle information of the vehicle 100 sent by the second application, the second application can apply for the second digital car key of the vehicle 100 based on the vehicle information of the vehicle 100. Specifically, please refer to the description in the embodiments of Figures 7J-7L, and this application will not be repeated here.

[0271] The electronic device 200 is not limited to obtaining the second digital car key of the vehicle 100 in the above manner. The electronic device 200 can also obtain the second digital car key of the vehicle 100 in other manners, which is not limited in this application.

[0272] Optionally, this application uses the example of how the electronic device 200 applies for the digital key of the vehicle 100 to illustrate. The electronic device 300 or other devices can also apply for the digital key of the vehicle 100 in the manner shown in FIG. 7A to FIG. 7U .

[0273] Optionally, for different devices, the digital car keys of the vehicle 100 generated by the vehicle server may be the same or different, and this application does not limit this.

[0274] Optionally, in some embodiments, the electronic device 300 may rely solely on the second application to apply for the digital key of the vehicle 100 in the manner shown in FIG7A to FIG7W . This application does not limit this.

[0275] When electronic device 200 or electronic device 300 obtains the digital key of vehicle 100, electronic device 200 or electronic device 300 can receive the user's operation in the first application and control vehicle 100 based on the digital key of vehicle 100. Electronic device 200 or electronic device 300 can also receive the user's operation in the second application and control vehicle 100 based on the digital key of vehicle 100. The following embodiments of this application are described using the example of a user operating the first application to control vehicle 100 based on the digital key of vehicle 100.

[0276] Next, the vehicle control method provided in this application is described in detail in combination with application scenarios.

[0277] Multiple devices of the same user control the vehicle 100

[0278] In some embodiments, a user may own multiple devices. For example, user A owns both electronic device 200 and electronic device 300. User A's electronic devices 200 and 300 have established a trusted relationship, and a communication connection may also be established between electronic devices 300 and 200. When user A approaches vehicle 100 and needs to control vehicle 100, electronic device 200 first establishes a Bluetooth connection with vehicle 100, and electronic device 300 loses the Bluetooth connection with vehicle 100. Without disconnecting electronic device 200 from vehicle 100, user A can operate electronic device 300 to issue a first control command to vehicle 100. If electronic devices 200 and 300 have established a communication connection, are trusted devices, and both have applied for a digital key for vehicle 100, electronic device 300 can send the first control command to electronic device 200, which then transmits the first control command to vehicle 100 via the Bluetooth connection. Vehicle 100 receives and responds to the first control command, executing it. This allows other devices to send vehicle control commands via the Bluetooth channel between the device and the vehicle without disconnecting the Bluetooth connection between the device and the vehicle.

[0279] Exemplarily, when the electronic device 200 is the mobile phone of user A and the electronic device 300 is the watch of user A, a trusted relationship has been established between user A's mobile phone and user A's watch. When user A approaches the vehicle 100 and needs to control the vehicle 100, user A's mobile phone has established a Bluetooth connection with the vehicle 100, and user A's mobile phone is placed in user A's backpack and is inconvenient to take out. Then at this time, user A can operate on the watch worn on the wrist and send a first control instruction to the vehicle 100. The first control instruction can be sent to the vehicle 100 through the Bluetooth connection channel between user A's mobile phone and the vehicle 100. In this way, the convenience of controlling the vehicle by multiple devices of the same user is greatly improved.

[0280] FIGS. 8A-8E illustrate a schematic diagram of an electronic device 300 controlling a vehicle through an electronic device 200.

[0281] Exemplarily, the electronic device 200 can be a mobile phone, and the electronic device 300 can be a watch.

[0282] A third application is installed on the electronic device 300, and the user can operate on the third application to control the vehicle 100. The third application can be an application that is the same as or similar to the first application or the second application in the electronic device.

[0283] The electronic device 300 can receive an input operation (such as a click) on the application icon of the third application. In response to the user's input operation, the electronic device 300 can display the user interface 810 shown in FIG. 8A.

[0284] When the electronic device 300 also applies for the digital car key of the vehicle 100, a card corresponding to the first digital car key of the vehicle 100 is displayed in the user interface 810. The logo of the vehicle, "AITO M7", is shown on the card to prompt the user that this card is the card corresponding to the digital car key of the vehicle 100. Multiple control options are also shown on the card, such as the car lock open / close option, the trunk open / close option, the window open / close option, the engine open / close option, etc. Only some control options of the vehicle 100 are shown on the card, and the electronic device 200 can receive a sliding operation (such as a right or left sliding operation) on the card 7401 by the user and display other control options that are not shown.

[0285] In some embodiments, the electronic device 300 can obtain the first digital car key of the vehicle 100 in the manner shown in FIGS. 7A-7O.

[0286] In other embodiments, the electronic device 300 establishes a trusted relationship with the electronic device 200. After the electronic device 200 applies for the first digital car key of the vehicle 100 in the manner of Figures 7A-7O, the electronic device 200 can synchronize the first digital car key of the vehicle 100 and save it on the electronic device 300. The electronic device 200 no longer needs to apply for the first digital car key of the vehicle 100 in the manner of Figures 7A-7O, so as to save the operation of the electronic device 300.

[0287] For example, as shown in Figure 8A, the electronic device 300 can receive a user input operation (such as a single click) for the vehicle lock open / close option in the user interface 810. In response to the user's input operation, when the electronic device 300 has not established a Bluetooth connection with the vehicle 100, the electronic device 300 can generate a first control instruction and send the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction to the electronic device 200.

[0288] Optionally, in some embodiments, after the electronic device 300 receives a user input operation for the vehicle lock on / off option in the user interface 810, the electronic device 300 may verify the user's identity and, if the identity verification is successful, perform subsequent operations. This improves the security of the electronic device 300 controlling the vehicle 100 via the digital vehicle key.

[0289] Optionally, before the user operates the third application to control the vehicle 100 via the digital vehicle key, the electronic device 300 may receive a user operation to enable an identity verification function in the third application. After the identity verification function is enabled, the electronic device 300 may verify the user's identity after receiving the user's input operation for the vehicle lock on / off option in the user interface 810. In other embodiments, if the identity verification function is disabled in the third application, the electronic device 300 may not verify the user's identity after receiving the user's input operation for the vehicle lock on / off option in the user interface 810.

[0290] Optionally, the electronic device 300 may also require verification of the user's identity by default, which is not limited in this application.

[0291] Optionally, identity authentication methods may include but are not limited to: face recognition, fingerprint recognition, voiceprint recognition, password matching, etc.

[0292] After receiving the vehicle information of vehicle 100, key information of the first digital vehicle key, and the first control instruction from electronic device 300, electronic device 200 can determine whether electronic device 200 has applied for the digital vehicle key of vehicle 100 based on the vehicle information of vehicle 100. For example, electronic device 200 determines that electronic device 200 has applied for the second digital vehicle key of vehicle 100. If the second digital vehicle key and the first digital vehicle key are of the same key type, electronic device 200 can encrypt the first control instruction based on the second digital vehicle key to obtain an encrypted first control instruction. Electronic device 200 then transmits the encrypted first control instruction and the device information of electronic device 200 to vehicle 100 via Bluetooth. After receiving the encrypted first control instruction and the device information of electronic device 200, vehicle 100 can obtain the second digital vehicle key based on the device information of electronic device 200, decrypt the encrypted first control instruction based on the second digital vehicle key to obtain the first control instruction, and execute the first control instruction, for example, to unlock vehicle 100. In this way, electronic device 300 controls vehicle 100 through electronic device 200.

[0293] Optionally, in some embodiments, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control instruction sent by the electronic device 300, the electronic device 200 may also verify the user's identity and, if the identity verification is successful, perform subsequent operations. This improves the security of the electronic device 200 controlling the vehicle 100 via the digital vehicle key.

[0294] Optionally, before the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300, the electronic device 200 may receive a user operation to enable the identity verification function. After the identity verification function is enabled, the electronic device 200 may verify the user's identity after receiving the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300. In other embodiments, if the identity verification function is disabled, the electronic device 200 may not verify the user's identity after receiving the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300.

[0295] Optionally, the electronic device 200 may also require verification of the user's identity by default, which is not limited in this application.

[0296] Optionally, identity authentication methods may include but are not limited to: face recognition, fingerprint recognition, voiceprint recognition, password matching, etc.

[0297] Optionally, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, if the electronic device 200 needs to verify the user's identity, the electronic device 200 and the electronic device 300 have established a trusted relationship, and the electronic device 200 can also verify the user's identity through the electronic device 300.

[0298] After the vehicle 100 executes the first control instruction, the vehicle 100 may send a feedback message to the electronic device 200 via the Bluetooth connection. The electronic device 200 then sends the feedback message to the electronic device 300 to prompt the user A that the user A has successfully controlled the vehicle 100 through the electronic device 300.

[0299] Optionally, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may display the prompt message 8101 shown in Figure 8B. The prompt message 8101 may include the text "The HUA WEIP60 has been unlocked by "Lisa's HUA WEIP60"". The prompt message 8101 is used to prompt the user that user A has successfully controlled the vehicle 100 through the electronic device 200.

[0300] Optionally, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may also display the user interface 820 shown in FIG8C . The user interface 820 is similar to the user interface 810 , except that the electronic device 300 changes the display format of the vehicle lock on / off option to prompt the user that the vehicle 100 is currently unlocked.

[0301] In some embodiments, after the electronic device 300 receives a user input operation for the vehicle lock on / off option in the user interface 810, and if a Bluetooth connection is established between the electronic device 300 and the vehicle 100, the electronic device 300 can directly control the vehicle 100 based on the first digital vehicle key obtained by the application. Specifically, the electronic device 300 can encrypt the first control instruction based on the first digital vehicle key to obtain an encrypted second control instruction, and then send the encrypted second control instruction and the device information of the electronic device 300 to the vehicle 100 via the Bluetooth connection. After receiving the encrypted second control instruction and the device information of the electronic device 300, the vehicle 100 can obtain the first digital vehicle key based on the device information of the electronic device 300, decrypt the encrypted second control instruction based on the first digital vehicle key to obtain the first control instruction, and execute the first control instruction, for example, to unlock the vehicle 100. In this way, the electronic device 300 can directly control the vehicle 100 using the first digital vehicle key.

[0302] After the vehicle 100 executes the first control instruction, the vehicle 100 may send a feedback message to the electronic device 300 via the Bluetooth connection to prompt the user A that the user A has successfully controlled the vehicle 100 through the electronic device 300 .

[0303] Optionally, after the electronic device 300 receives the feedback message sent by the vehicle 100, the electronic device 300 may display the prompt message 8102 shown in Figure 8D. The prompt message 8102 may include the text "The WATCH GT 3 has been unlocked by Lisa's WATCH GT 3". The prompt message 8102 is used to prompt the user that user A has successfully controlled the vehicle 100 through the electronic device 300.

[0304] Optionally, the prompt information shown in FIG8D is different from the prompt information shown in FIG8C , thereby notifying the user which device the electronic device 300 uses to control the vehicle 100. In other embodiments, the prompt information shown in FIG8D and the prompt information shown in FIG8C may also be the same, and this application does not limit this.

[0305] In some embodiments, after the electronic device 300 can receive the user's input operation for the vehicle lock open / close option in the user interface 810, the electronic device 300 has not established a communication connection with the electronic device 200, and the electronic device 300 cannot control the vehicle 100 through the electronic device 200. The electronic device 300 can display the prompt message 8103 shown in Figure 8E, which is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0306] In some embodiments, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 200 does not establish a Bluetooth connection with the vehicle 100, or after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 300 determines that the electronic device 300 has not applied for the digital car key of the vehicle 100, or after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 200 determines that the digital car key of the vehicle 100 applied for by the electronic device 200 is different from the type of the digital car key of the vehicle 100 applied for by the electronic device 300, the electronic device 200 may send a feedback message to the electronic device 300, which is used to indicate that the vehicle 100 cannot be controlled at present. For example, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may also display the prompt message 8103 shown in FIG8E. The prompt message 8103 is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0307] FIG9A shows a flow chart of a method in which the electronic device 300 controls the vehicle 100 via the electronic device 200 .

[0308] Optionally, the electronic device 200 may be referred to as a first electronic device, the electronic device 300 may be referred to as a second electronic device, and the vehicle 100 may be referred to as a first vehicle.

[0309] S901: The electronic device 300 and the electronic device 200 establish a trusted communication connection.

[0310] For example, the electronic device 300 may be a watch, and the electronic device 200 may be a mobile phone.

[0311] The electronic device 300 may establish a trusted relationship with the electronic device 200 in the following manners, but not limited to the following.

[0312] Method 1: The electronic device 200 establishes a trusted relationship with the electronic device 300 by scanning a code.

[0313] For example, as shown in FIG9B , the electronic device 300 may display a QR code image 9001 , and the electronic device 200 may scan the QR code image 9001 through a camera to establish a trusted relationship with the electronic device 300 .

[0314] Method 2: The electronic device 200 and the electronic device 300 establish a trusted relationship by logging into the same user account.

[0315] When electronic device 300 and electronic device 200 are multiple devices of the same user, a first user account is logged in on electronic device 200, and the user can also log in to the first account on electronic device 300. There is a trusted relationship between electronic device 200 and electronic device 300 that are logged in with the first user account.

[0316] Method 3: The electronic device 200 and the electronic device 300 log in to different user accounts, and the different user accounts are associated with each other, so there is a trusted relationship between the electronic device 200 and the electronic device 300.

[0317] In the case where electronic device 300 and electronic device 200 are different users or multiple devices of the same user, a first user account is logged into electronic device 200, and a second user account is logged into electronic device 300. The first user account and the second user account are different, but the first user account and the second user account are associated with each other. For example, if electronic device 200 and electronic device 300 are two devices owned by different family members in a household, then a trusted relationship exists between electronic device 200 and electronic device 300.

[0318] The method of determining the trust relationship is not limited to the above method. The electronic device 200 and the electronic device 300 can also establish a trust relationship in other ways, which is not limited in this application.

[0319] The communication connection between the electronic device 300 and the electronic device 200 can be any one of a Bluetooth connection, a network connection or a server connection. The communication connection between the electronic device 300 and the electronic device 200 can also be other methods, which is not limited in this application.

[0320] Optionally, the trust relationship between the electronic device 200 and the electronic device 300 may be authenticated periodically or irregularly. This application does not limit the order of authenticating the trust relationship and establishing the communication relationship between the electronic device 200 and the electronic device 300.

[0321] Optionally, the communication connection between the electronic device 200 and the electronic device 200 can be referred to as a first communication connection. The first communication connection can be any one of a Bluetooth connection, a network connection, or a server connection. The first communication connection can also be other connection modes, which are not limited in this application.

[0322] Exemplarily, when the distance between the location of the electronic device 300 and the location of the electronic device 200 is within a preset distance, a Bluetooth connection, a network connection, or a server connection can be established between the electronic device 300 and the electronic device 200, and the electronic device 300 and the electronic device 200 can communicate via the Bluetooth connection, the network connection, or the server connection. The electronic device 300 and the electronic device 200 also need to determine whether they are trusted devices. In one possible implementation, the electronic device 300 and the electronic device 200 can respectively send the account ID of the user account logged in on their respective devices to the server. The server can determine the relationship between the two user accounts based on the account ID of the user account sent by the electronic device 300 and the electronic device 200. If the account IDs of the two user accounts are the same or correlated with each other, the server can determine that there is a trusted relationship between the electronic device 200 and the electronic device 300. The server can send messages to the electronic device 200 and the electronic device 300 respectively to inform the electronic device 200 and the electronic device 300 that there is a trusted relationship between the two. In other possible implementations, the electronic device 300 may send the account ID of the user account logged in on the electronic device 300 to the electronic device 200, and the electronic device 200 may obtain the account ID of the user account logged in on the electronic device 200. The electronic device 200 may determine the relationship between the two user accounts. If the account IDs of the two user accounts are the same or related to each other, the electronic device 200 may determine that there is a trusted relationship between the electronic device 200 and the electronic device 300. The electronic device 200 may send a message to the electronic device 300 to inform the electronic device 300 that there is a trusted relationship between the two. In other possible implementations, the electronic device 200 may also send the account ID of the user account logged in on the electronic device 200 to the electronic device 300, and the electronic device 300 may obtain the account ID of the user account logged in on the electronic device 300. The electronic device 300 may determine the relationship between the two user accounts. If the account IDs of the two user accounts are the same or related to each other, the electronic device 300 may determine that there is a trusted relationship between the electronic device 200 and the electronic device 300. The electronic device 300 may send a message to the electronic device 200 to inform the electronic device 200 that there is a trusted relationship between the two.

[0323] Exemplarily, when the distance between the location of the electronic device 300 and the location of the electronic device 200 is not within the preset distance, a server connection can be established between the electronic device 300 and the electronic device 200. The electronic device 300 and the electronic device 200 can communicate with each other through the server connection. The electronic device 300 and the electronic device 200 also need to determine whether both are trusted devices. The electronic device 300 and the electronic device 200 can respectively send the account ID of the user account logged in on their respective devices to the server. The server can determine the relationship between the two user accounts based on the account ID of the user account sent by the electronic device 300 and the electronic device 200. If the account IDs of the two user accounts are the same or related to each other, the server can determine that there is a trusted relationship between the electronic device 200 and the electronic device 300. The server can send messages to the electronic device 200 and the electronic device 300 respectively to inform the electronic device 200 and the electronic device 300 that there is a trusted relationship between the two.

[0324] S902 : The electronic device 200 and the vehicle 100 establish a Bluetooth connection.

[0335] S904 : The electronic device 300 needs to determine whether a communication connection has been established between the electronic device 300 and the electronic device 200 .

[0336] If the electronic device 300 determines that the electronic device 300 has not established a Bluetooth connection with the vehicle 100, the electronic device 300 needs to determine whether the electronic device 300 has established a communication connection with the electronic device 200. If it is determined that the electronic device 300 has established a communication connection with the electronic device 200, the electronic device 300 can control the vehicle 100 through the electronic device 200 that has established a communication connection with the electronic device 300, that is, execute S905-S919.

[0337] When it is determined that the electronic device 300 has not established a communication connection with the electronic device 200 , the electronic device 300 is also unable to control the vehicle 100 through the electronic device 200 that has established a communication connection with the electronic device 300 , and the process ends.

[0338] Optionally, when the electronic device 300 has not established a communication connection with the electronic device 200 and the electronic device 300 is currently unable to send a first control instruction to the vehicle 100 through the electronic device 300, the electronic device 300 may display a prompt message 8103 as shown in FIG8E , and the prompt message 8103 is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0339] S905 : The electronic device 300 sends the vehicle information of the vehicle 100 and the key information of the first digital vehicle key to the electronic device 200 .

[0340] Optionally, in some embodiments, after the electronic device 200 receives the vehicle information of the vehicle 100 and the key information of the first digital vehicle key from the electronic device 300, the electronic device 200 may also verify the user's identity and, if the identity verification is successful, perform subsequent operations. This improves the security of the electronic device 200 controlling the vehicle 100 via the digital vehicle key.

[0341] Optionally, before the electronic device 200 receives the vehicle information of the vehicle 100 and the key information of the first digital vehicle key sent by the electronic device 300, the electronic device 200 may receive a user operation to enable the identity verification function. After the identity verification function is enabled, the electronic device 200 may verify the user's identity after receiving the vehicle information of the vehicle 100 and the key information of the first digital vehicle key sent by the electronic device 300. In other embodiments, if the identity verification function is disabled, the electronic device 200 may not verify the user's identity after receiving the vehicle information of the vehicle 100 and the key information of the first digital vehicle key sent by the electronic device 300.

[0342] Optionally, the electronic device 200 may also require verification of the user's identity by default, which is not limited in this application.

[0343] Optionally, identity authentication methods may include but are not limited to: face recognition, fingerprint recognition, voiceprint recognition, password matching, etc.

[0344] When the electronic device 300 determines that the electronic device 300 has established a communication connection with the electronic device 200, the electronic device 300 can control the vehicle 100 through the electronic device 200 that has established a communication connection with the electronic device 300, and the electronic device 300 can send the vehicle information of the vehicle 100 and the key information of the first digital car key to the electronic device 200.

[0345] The vehicle information of the vehicle 100 is used by the electronic device 200 to determine whether the electronic device 200 has applied for a digital vehicle key for the vehicle 100 .

[0346] The key information of the first digital car key is used by the electronic device 200 to determine whether the electronic device 200 and the electronic device 300 have applied for the same type of digital car key. Only when the electronic device 300 has applied for the same type of digital car key for the same car can the electronic device 300 control the vehicle 100 through the electronic device 200.

[0347] Exemplarily, the key information of the first digital car key may include but is not limited to one or more of the following: key type, key identification, etc. For example, when the first digital car key is a Bluetooth car key, the key type of the first digital car key may be a Bluetooth car key.

[0348] The vehicle information of vehicle 100 may include but is not limited to one or more of the following: vehicle identification code (or vehicle identification), vehicle model, vehicle license plate number, vehicle manufacturer, vehicle production date, vehicle engine model, etc.

[0349] S906 : The electronic device 200 obtains key information of the second digital vehicle key based on the vehicle information of the vehicle 100 .

[0350] If the electronic device 200 can obtain the key information of the second digital key based on the vehicle information of the vehicle 100, it means that the electronic device 200 has applied for the digital key of the vehicle 100. That is, the electronic device 300 and the electronic device 200 have applied for the digital key of the same vehicle.

[0351] If the electronic device 200 fails to obtain the digital car key based on the vehicle information of the vehicle 100 , it means that the electronic device 200 has not applied for the digital car key of the vehicle 100 , that is, the electronic device 300 and the electronic device 200 have not applied for the digital car key of the same vehicle.

[0352] S907: The electronic device 200 needs to determine whether the first digital car key and the second digital car key are of the same key type.

[0353] Optionally, the vehicle 100 may provide different types of digital car keys, such as a Bluetooth car key, an NFC car key, an ultra wide band (UWB) car key, etc. The embodiment of the present application is described by taking a Bluetooth car key as an example.

[0354] After receiving the vehicle information of the vehicle 100 and the key information of the first digital vehicle key sent by the electronic device 300 , the electronic device 200 can obtain the key information of the second digital vehicle key based on the vehicle information of the vehicle 100 .

[0355] The key information of the second digital car key may include but is not limited to one or more of the following: key type, key identification, etc. For example, when the second digital car key is a Bluetooth car key, the key type of the second digital car key may be a Bluetooth car key.

[0356] After obtaining the key information of the first digital vehicle key and the key information of the second digital vehicle key, the electronic device 200 needs to determine whether the key type of the first digital vehicle key and the key type of the second digital vehicle key are the same. Only when the key type of the first digital vehicle key and the key type of the second digital vehicle key are the same can the electronic device 300 control the vehicle 100 through the electronic device 200.

[0357] Optionally, the electronic device 200 further needs to determine whether the electronic device 200 has established a Bluetooth connection with the vehicle 100. Only when the electronic device 200 has established a Bluetooth connection with the vehicle 100 can the electronic device 300 control the vehicle 100 through the electronic device 200.

[0358] When the key type of the first digital car key and the key type of the second digital car key are the same, for example, the key type of the first digital car key and the key type of the second digital car key are both Bluetooth car keys, and the electronic device 200 and the vehicle 100 have established a Bluetooth connection, the electronic device 200 can control the vehicle 100 through the electronic device 300.

[0359] When the electronic device 300 determines that the key types of the first digital car key and the second digital car key are different, and / or the electronic device 200 has not established a Bluetooth connection with the vehicle 100, the electronic device 300 is also unable to control the vehicle 100 through the electronic device 200, and S907-S909 are executed.

[0360] When the electronic device 300 determines that the key types of the first digital car key and the second digital car key are the same and the electronic device 200 has established a Bluetooth connection with the vehicle 100, the electronic device 300 can control the vehicle 100 through the electronic device 200 and execute S910-S919.

[0361] It should be noted that S905, S906, and S907 are not limited to being executed after S904. S905, S906, and S907 can be executed periodically or irregularly. For example, before executing S904, S905, S906, and S907 have already been executed, and the electronic device 200 can directly obtain the execution results. In this way, on the one hand, when the electronic device 300 needs to control the vehicle 100 through the electronic device 200, the electronic device 300 does not need to execute S905, S906, and S907 again, and can directly determine whether the vehicle 100 can be controlled by the electronic device 200 based on the results of the periodic execution, which can speed up the speed at which the electronic device 300 controls the vehicle 100 through the electronic device 200. On the other hand, the digital car keys of the vehicles applied for by the electronic device 200 and the electronic device 300 may also change. For example, if a user applies for a new digital car key for a vehicle, S905, S906 and S907 are executed periodically or irregularly, and the execution results can be updated periodically or irregularly.

[0362] Optionally, the electronic device 200 may not execute S907 , and the electronic device 300 may not send the key information of the first digital car key to the electronic device 200 .

[0363] S908 : The electronic device 200 sends a verification failure message to the electronic device 300 .

[0364] S909. In response to the verification failure message, the electronic device 300 prompts that the operation has failed.

[0365] If the electronic device 300 determines that the first digital car key and the second digital car key are of different key types and / or the electronic device 200 has not established a Bluetooth connection with the vehicle 100, the electronic device 200 may send a verification failure message to the electronic device 300. In response to the verification failure message, the electronic device 300 prompts that the operation has failed.

[0366] For example, after receiving the verification failure message sent by the electronic device 200, the electronic device 300 may display a prompt message 8103 shown in FIG8E , where the prompt message 8103 is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0367] S910 , the electronic device 200 sends a verification passed message to the electronic device 300 .

[0368] S911. In response to the verification passed message, the electronic device 300 generates a first control instruction.

[0369] S912 : The electronic device 300 sends the first control instruction to the electronic device 200 .

[0370] When the electronic device 300 determines that the first digital vehicle key and the second digital vehicle key are of the same key type and the electronic device 200 has established a Bluetooth connection with the vehicle 100, the electronic device 200 may send a verification pass message to the electronic device 300. In response to the verification pass message, the electronic device 300 may generate a first control instruction and send the first control instruction to the electronic device 200.

[0371] The first control instruction may include, but is not limited to, one or more of the following: a version number of the first vehicle control instruction, a vehicle control operation type, etc. The vehicle control operation type may include, but is not limited to, any one of the following: unlock, lock, raise window, lower window, turn on air conditioning, turn off air conditioning, play music, pause music, etc.

[0372] Optionally, after the electronic device 200 receives the first control instruction sent by the electronic device 200, the electronic device 200 also needs to verify the legitimacy of the first control instruction. Specifically, the electronic device 200 can obtain the fourth vehicle control instruction version number in the electronic device 200 based on the vehicle control operation type in the first control instruction. The fourth vehicle control instruction has the same vehicle control operation type as the first vehicle control instruction. When the fourth vehicle control instruction version number is the same as the first vehicle control instruction version number, the first control instruction is legal, and the electronic device 200 can execute S913. If the fourth vehicle control instruction version number is different from the first vehicle control instruction version number, the first control instruction is illegal, the electronic device 200 cannot execute S913, and the electronic device 200 can send a feedback message to the electronic device 300 to inform the electronic device 300 that the vehicle 100 cannot be controlled by the electronic device 200 at present. Optionally, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may display a prompt message 8103 as shown in FIG8E , where the prompt message 8103 is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0373] Optionally, in addition to sending the first control instruction to the electronic device 200, the electronic device 300 may also send the vehicle information of the vehicle 100 and the key information of the first digital key to the electronic device 200. In this way, in addition to verifying the legitimacy of the first control instruction, the electronic device 200 also needs to verify whether the vehicle information of the vehicle 100 and the key information of the first digital key sent along with the first control instruction are consistent with the vehicle information of the vehicle 100 and the key information of the first digital key sent by the electronic device 300 in S905. If they are consistent, the electronic device 300 can then determine whether the first control instruction is legitimate.

[0374] S913: The electronic device 200 encrypts the first control instruction based on the second digital vehicle key to obtain an encrypted first control instruction.

[0375] Optionally, before executing S913, the electronic device 200 may determine whether the first control command complies with the digital car key vehicle connection standard. It is understood that the digital car key vehicle connection standard specifies the formats of different types of control commands. For example, the format of the unlocking control command is different from the format of the window opening control command, so that the vehicle 100 can correctly identify different types of control commands.

[0376] When it is determined that the format of the first control instruction meets the requirements of the digital car key vehicle connection standard, the electronic device 200 may execute S913.

[0377] If it is determined that the format of the first control instruction does not meet the requirements of the digital car key vehicle connection standard, the electronic device 200 needs to generate a third control instruction based on the first control instruction, and the format of the third control instruction meets the requirements of the digital car key vehicle connection standard. Specifically, after the electronic device 300 obtains the first control instruction, the electronic device 300 can obtain the first vehicle control instruction version number and vehicle control operation type from the first control instruction. The electronic device 300 can obtain the third control instruction based on the first vehicle control instruction version number, vehicle control operation type, and the digital car key vehicle connection standard.

[0378] Optionally, the electronic device 200 may not perform the judgment step. After obtaining the first control instruction, the electronic device 200 may directly obtain the first vehicle control instruction version number and vehicle control operation type from the first control instruction, and then obtain the third control instruction based on the first vehicle control instruction version number, vehicle control operation type and digital car key vehicle connection specification standard.

[0379] The specific implementation of the electronic device 200 sending the third control instruction to the vehicle 100 is similar to the specific implementation of the electronic device 200 sending the first control instruction to the vehicle 100, and will not be repeated in this application.

[0380] S914 : The electronic device 200 sends the encrypted first control instruction and the device information of the electronic device 200 to the vehicle 100 via the first Bluetooth connection.

[0381] After the electronic device 200 confirms that the first control instruction is legitimate, the electronic device 200 may encrypt the first control instruction based on the second digital vehicle key to obtain an encrypted first control instruction, and transmit the encrypted first control instruction and the device information of the electronic device 200 to the vehicle 100 via a Bluetooth connection.

[0382] The device information of the electronic device 200 is used by the vehicle 100 to obtain the second digital vehicle key.

[0383] S915 : The vehicle 100 obtains the second digital vehicle key based on the device information of the electronic device 200 .

[0384] S916 : The vehicle 100 decrypts the encrypted first control instruction based on the second digital vehicle key to obtain the first control instruction.

[0385] Optionally, steps S913 to S916 may not be executed, and the electronic device 200 may only send the first control instruction to the first vehicle.

[0386] S917 : The vehicle 100 executes the first control instruction.

[0387] S918 , the vehicle 100 sends the execution result to the electronic device 200 .

[0388] S919 , the electronic device 200 sends the execution result to the electronic device 300 .

[0389] Optionally, the vehicle 100 stores the correspondence between device information of one or more devices and the digital car key.

[0390] Table 1

[0391] Table 1 shows a correspondence between device information stored in a vehicle 100 and a digital vehicle key. For example, the vehicle 100 stores device information for an electronic device 200 and a second digital vehicle key. Based on the device information of the electronic device 200, the vehicle 100 can obtain the second digital vehicle key and use the second digital vehicle key to control the vehicle 100.

[0392] The vehicle 100 also stores a correspondence between the device information of the electronic device 300 and the first digital car key. The vehicle 100 can obtain the first digital car key based on the device information of the electronic device 300, and the electronic device 300 can control the vehicle 100 through the first digital car key.

[0393] The vehicle 100 may also store the correspondence between device information of other devices and the digital vehicle key.

[0394] After the vehicle 100 receives the encrypted second control instruction and the device information of the electronic device 300 sent by the electronic device 300 , the vehicle 100 can obtain the first digital vehicle key based on the device information of the electronic device 300 .

[0395] The vehicle 100 can decrypt the encrypted second control instruction based on the first digital vehicle key to obtain the first control instruction and execute the first control instruction. After executing the first control instruction, the vehicle 100 also needs to send the execution result to the electronic device 300 to inform the electronic device 300 of the execution result of the vehicle 100.

[0396] For example, the first control instruction may be used to control the unlocking of the vehicle 100. After the vehicle 100 is unlocked, the vehicle 100 may inform the electronic device 300 of the execution result that the vehicle has been unlocked.

[0397] Optionally, after receiving the execution result sent by the vehicle 100, the electronic device 300 may display a prompt message, which is used to prompt the vehicle 100 that the first control instruction has been executed. For example, after the electronic device 300 receives the execution result sent by the vehicle 100 indicating that the vehicle has been unlocked, the electronic device 300 may display the prompt message 8101 shown in Figure 8B, which is used to prompt the user that user A has successfully controlled the vehicle 100 through the electronic device 300.

[0398] Optionally, the prompt information 8101 shown in FIG8B may also be referred to as third prompt information.

[0399] Optionally, before executing S904 , the electronic device 300 needs to determine whether a Bluetooth connection has been established between the electronic device 300 and the vehicle 100 .

[0400] When the electronic device 300 establishes a Bluetooth connection with the vehicle 100, the electronic device 300 can directly control the vehicle 100 based on the first digital vehicle key. Specifically, after the electronic device 300 receives a user operation and determines that a Bluetooth connection has been established between the electronic device 300 and the vehicle 100, the electronic device 300 can determine the first digital vehicle key based on the vehicle information of the vehicle currently to be controlled (e.g., the vehicle information of the vehicle 100). The first digital vehicle key is the digital vehicle key used to control the vehicle 100. After obtaining the first digital vehicle key, the electronic device 300 encrypts the first control instruction using the first digital vehicle key to obtain an encrypted second control instruction. The electronic device 300 then sends the encrypted second control instruction and the device information of the electronic device 300 to the vehicle 100. The device information of the electronic device 300 is used by the vehicle 100 to determine the first digital vehicle key. Referring to the description in S915-S919, there are multiple device information within the vehicle 100 that correspond to digital vehicle keys. After vehicle 100 receives the encrypted second control instruction and device information of electronic device 300 sent by electronic device 200, vehicle 100 can obtain the first digital vehicle key based on the device information of electronic device 300. Vehicle 100 can decrypt the encrypted second control instruction using the first digital vehicle key to obtain the first control instruction and execute the first control instruction. After executing the first control instruction, vehicle 100 must also send the execution result to electronic device 300 to inform electronic device 300 of the execution result of vehicle 100. For example, the first control instruction can be used to control the unlocking of vehicle 100. After vehicle 100 unlocks vehicle 100, vehicle 100 can notify electronic device 300 of the execution result that the vehicle has been unlocked. Optionally, after receiving the execution result sent by vehicle 100, electronic device 300 can display a prompt message, which is used to indicate that vehicle 100 has executed the first control instruction. For example, after the electronic device 300 receives the vehicle unlocking result sent by the vehicle 100, the electronic device 300 may display the prompt message 8102 shown in FIG8D . The prompt message 8102 is used to prompt the user that user A has successfully controlled the vehicle 100 through the electronic device 200. Optionally, the prompt message 8102 shown in FIG8D may also be referred to as the fourth prompt message.

[0401] When the electronic device 300 has not established a Bluetooth connection with the vehicle 100 , the electronic device 300 may control the vehicle 100 through the electronic device 200 that has established a communication connection with the electronic device 300 .

[0402] Optionally, in the embodiment of FIG9A , the data transmission path between the electronic device 300 and the electronic device 200 may be as follows: the first application in the electronic device 300 may obtain the transmission data (e.g., the first control instruction or vehicle information of the vehicle 100), the third application in the electronic device 300 may send the transmission data to the fourth application (e.g., a sports and health application) on the electronic device 200, and the fourth application on the electronic device 200 may then send the transmission data to the first application on the electronic device 200. The third application on the electronic device 300 may be the same or similar application as the first application on the electronic device 200.

[0403] Optionally, the data transmission path between the electronic device 200 and the electronic device 300 in the embodiment of Figure 9A can be as follows: the first application on the electronic device 200 sends the transmission data (such as a verification pass message or execution result, etc.) to the fourth application on the electronic device 200, and the fourth application on the electronic device 200 then sends the transmission data to the third application in the electronic device 300.

[0404] Multiple devices of different users control the vehicle 100

[0405] In other embodiments, user A owns electronic device 200, and user B owns electronic device 300. Electronic devices 200 and 300 have not established a trusted relationship, and devices that have not established a trusted relationship cannot collaboratively control the vehicle. Alternatively, electronic device 200 can proactively establish a trusted relationship with electronic device 300 and generate a trusted credential. Each electronic device 200 and electronic device 300 stores a trusted credential, which is used to verify whether the device is a trusted device.

[0406] Specifically, if electronic device 200 first establishes a Bluetooth connection with vehicle 100, electronic device 300 cannot continue to establish a Bluetooth connection with vehicle 100. When user B needs to control vehicle 100 on electronic device 300, without disconnecting the Bluetooth connection established between electronic device 200 and vehicle 100, user B can operate on electronic device 300 and send a first control instruction and a trusted credential to electronic device 200. After electronic device 300 receives the first control instruction and trusted credential sent by electronic device 200, electronic device 200 determines that electronic device 200 is a trusted device based on the trusted credential. If both electronic device 200 and electronic device 300 have applied for a digital key for vehicle 100, electronic device 200 can send the first control instruction to vehicle 100. Vehicle 100 receives and responds to the first control instruction, executing the first control instruction. This allows users to actively trigger the establishment of a trusted relationship between non-trusted devices. Without disconnecting the Bluetooth connection between the device and the vehicle, devices that the user has actively established a trusted relationship with can collaboratively control the vehicle.

[0407] For example, when electronic device 200 is the mobile phone of user A and electronic device 300 is the mobile phone of user B, user A and user B are friends, but electronic device 200 and electronic device 300 have not established a trusted relationship. Then user A can actively establish a trusted relationship with user B's electronic device 300 through electronic device 200, and trusted credentials are stored in electronic device 200 and electronic device 300 respectively. User A and user B are both riding in vehicle 100, and user A's electronic device 200 has established a Bluetooth connection with vehicle 100. When user B needs to control vehicle 100 through electronic device 300, without disconnecting the Bluetooth connection established between electronic device 200 and vehicle 100, electronic device 200 can establish a communication connection with electronic device 300 and send a first control instruction and a trusted credential to electronic device 200. After receiving the first control instruction and trusted credentials sent by electronic device 200, electronic device 200 determines that electronic device 200 is a trusted device based on the trusted credentials. If electronic device 200 and electronic device 300 have both applied for the digital key of vehicle 100, electronic device 200 will then send the first control instruction to vehicle 100, and vehicle 100 can execute the first control instruction. This greatly improves the convenience of different users using different electronic devices to control the vehicle.

[0408] 10A-10J are schematic diagrams showing an electronic device 300 controlling a vehicle via an electronic device 200 .

[0409] The electronic device 200 actively establishes a trusted relationship with the electronic device 300 ( FIG. 10A - FIG. 10D ).

[0410] After the electronic device 200 applies for the digital car key of the vehicle 100 , the electronic device 300 may display the user interface 790 shown in FIG. 10A .

[0411] For example, as shown in FIG10A , the electronic device 200 may receive a user input operation (e.g., a single click) for a credibility authentication option in the user interface shown in FIG10A . In response to the user input operation, the electronic device 200 may display a window 1101 shown in FIG10B . Window 1101 includes device identifiers of one or more devices discovered by the electronic device 200, such as “TOM’s Mate 50” and “Nacy’s NOVA 11.” The device identifier “TOM’s Mate 50” may be the device identifier of the electronic device 300, and the device identifier “Nacy’s NOVA 11” may be the device identifiers of other devices near the electronic device 200.

[0412] Optionally, before the electronic device 200 displays the window 1101 shown in Figure 10B, the electronic device 200 may display a prompt message, which is used to instruct the user to turn on the Bluetooth of the electronic device 200 and turn on the Bluetooth of other devices that need to establish a trusted relationship with the electronic device 200, so that the electronic device 200 can discover other devices near the electronic device 200.

[0413] When electronic device 200 needs to establish a trusted relationship with electronic device 300, as shown in Figure 10B, electronic device 200 can receive the user's input operation (such as a single click) for the device identifier "TOM's Mate 50" in window 1101. In response to the user's input operation, electronic device 200 can display window 1002 shown in Figure 10C, which is used to indicate that electronic device 200 is negotiating to establish a trusted relationship with electronic device 300.

[0414] In response to the user's input operation, the electronic device 200 may send a request to establish a trusted relationship to the electronic device 300 .

[0415] After electronic device 300 receives the request to establish a trusted relationship from electronic device 200, electronic device 300 may display window 1006 shown in FIG10D . Window 1006 includes a prompt message "Do you want to establish a trusted relationship with Lisa's HUA WEIP60?" Window 1006 also includes a Continue option and a Cancel option. The user can select Continue to establish a trusted relationship with electronic device 200, or select Cancel to refuse to establish a trusted relationship with electronic device 200.

[0416] For example, as shown in FIG10D , the electronic device 300 may receive a user input operation (eg, a single click) for the Continue option in the window 1006 . In response to the user input operation, the electronic device 300 may establish a trusted relationship with the electronic device 200 .

[0417] In one possible implementation, the steps for establishing a trusted relationship between electronic device 200 and electronic device 300 may be as follows: electronic device 200 may obtain parameter information of electronic device 200. The parameter information of electronic device 200 may include, but is not limited to, one or more of the following: a device identifier of electronic device 200, a device type of electronic device 200, a first random number, etc. The first random number is used by electronic device 200 and electronic device 300 to generate a trusted credential. Electronic device 200 may also send the parameter information of electronic device 200 to electronic device 300. After receiving the parameter information of electronic device 200 sent by electronic device 200, electronic device 300 stores the parameter information of electronic device 200 and obtains the parameter information of electronic device 300. Thereafter, electronic device 300 sends the parameter information of electronic device 300 to electronic device 200. The parameter information of electronic device 300 may include, but is not limited to, one or more of the following: a device identifier of electronic device 300, a device type of electronic device 300, a second random number, etc. The second random number is also used by electronic device 200 and electronic device 300 to generate a trusted credential. After the electronic device 200 and the electronic device 300 obtain the first random number and the second random number, the electronic device 200 and the electronic device 300 can generate a trusted credential based on the first random number and the second random number, and save the trusted credential. The trusted credential is used by the electronic device 200 and the electronic device 300 to verify whether the two parties are trusted devices. Optionally, after the electronic device 300 generates the trusted credential based on the first random number and the second random number, the electronic device 300 can send a feedback message to the electronic device 200, which is used to indicate to the electronic device 300 that the electronic device 200 has generated the trusted credential.

[0418] In other possible implementations, the steps for establishing a trusted relationship between electronic device 200 and electronic device 300 may be as follows: electronic device 200 may obtain device information of electronic device 200. The device information of electronic device 200 may include, but is not limited to, one or more of the following: a device identifier of electronic device 200, a device type of electronic device 200, etc. Electronic device 200 may also transmit the device information of electronic device 200 to electronic device 300. After receiving the device information of electronic device 200 transmitted by electronic device 200, electronic device 300 may store the device information of electronic device 200. Based on the device information of electronic device 200, electronic device 300 may determine that electronic device 200 is a trusted device. Electronic device 300 may also obtain device information of electronic device 300. The device information of electronic device 300 may include, but is not limited to, one or more of the following: a device identifier of electronic device 300, a device type of electronic device 300, etc. Electronic device 300 may also transmit the device information of electronic device 300 to electronic device 200. After receiving the device information of electronic device 300 transmitted by electronic device 300, electronic device 200 may store the device information of electronic device 300. The electronic device 200 may determine that the electronic device 300 is a trusted device based on the device information of the electronic device 300 .

[0419] Not limited to the above methods, the electronic device 200 and the electronic device 300 can also establish a trusted relationship based on other methods, which is not limited in this application.

[0420] Optionally, after the electronic device 200 and the electronic device 300 establish a trusted relationship, the electronic device 200 may display a prompt message 1003 as shown in FIG10E . The prompt message 1003 is used to prompt the user that the electronic device 200 and the electronic device 300 have established a trusted relationship.

[0421] Optionally, after the electronic device 200 and the electronic device 300 establish a trusted relationship, the electronic device 200 may also display a message "A trusted relationship has been established with Tom's Mate 50" in the user interface 1004 shown in FIG10F to prompt the user that the electronic device 200 and the electronic device 300 have established a trusted relationship.

[0422] Optionally, Figures 10A-10F illustrate the example of electronic device 200 actively initiating trusted authentication to electronic device 300. In other embodiments, electronic device 300 may also actively initiate trusted authentication to electronic device 200, and this application does not limit this.

[0423] Optionally, Figures 10A-10F are described using the first application as an example. In other embodiments, the electronic device 200 may also proactively initiate trusted authentication to the electronic device 300 in the second application, or the electronic device 200 may proactively initiate trusted authentication to the electronic device 300 in combination with the first application and the second application, and this application does not limit this. This application only describes the example of the electronic device 200 proactively initiating trusted authentication to the electronic device 300 in the first application.

[0424] The electronic device 300 controls the vehicle 100 via the electronic device 200 based on the digital vehicle key ( FIG. 10F to FIG. 10J ).

[0425] After the electronic device 200 actively establishes a trusted relationship with the electronic device 300 in accordance with Figures 10A to 10F, when a communication connection is established between the electronic device 300 and the electronic device 200, a Bluetooth connection is established between the electronic device 200 and the vehicle 100, and both the electronic device 300 and the electronic device 200 apply for the digital car key of the vehicle 100, the electronic device 300 can control the vehicle 100 based on the digital car key through the electronic device 200.

[0426] For example, a first application may also be installed on the electronic device 300 , and the user may control the vehicle 100 based on the digital car key within the first application.

[0427] For example, the electronic device 300 may be the mobile phone of user B, and the electronic device 200 may be the mobile phone of user A.

[0428] Electronic device 300 may receive a user input operation (e.g., a single click) on the application icon of the first application. In response to the user input operation, electronic device 300 may display user interface 1004 shown in FIG10F . If electronic device 300 has also applied for a digital key for vehicle 100, after opening the first application, electronic device 300 may display card 1005 in user interface 1004. Card 1005 displays the vehicle's logo "Wenjie M7" to indicate to the user that card 1005 corresponds to the digital key for vehicle 100. Card 1005 also displays multiple control options, such as an option to open / close the locks, open / close the trunk, open / close the windows, and start / stop the engine. Card 1005 only displays some of the control options for vehicle 100. Electronic device 300 may receive a user swipe operation (e.g., a swipe to the right or left) on card 1005 to display other control options not displayed.

[0429] For example, as shown in Figure 10F, the electronic device 300 can receive a user input operation (such as a single click) for the window opening / closing option in the card 1005. In response to the user's input operation, when the electronic device 300 has not established a Bluetooth connection with the vehicle 100, the electronic device 300 can generate a first control instruction and send the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction to the electronic device 200.

[0430] Optionally, in some embodiments, after the electronic device 300 receives the user's input operation for the window opening / closing option on the card 1005, the electronic device 300 can verify the user's identity and, if the identity verification is successful, perform subsequent operations. This improves the security of the electronic device 300 controlling the vehicle 100 through the digital car key.

[0431] Optionally, before the user operates the first application to control the vehicle 100 via the digital car key, the electronic device 300 may receive a user operation to enable the identity verification function in the first application. After the identity verification function is enabled, the electronic device 300 may verify the user's identity after receiving the user's input operation for the window open / close option in the user interface 810. FIG10F shows that the identity verification function of the electronic device 300 is enabled. In other embodiments, if the identity verification function in the first application is disabled, the electronic device 300 may not verify the user's identity after receiving the user's input operation for the window open / close option in the user interface 810.

[0432] Optionally, the electronic device 300 may also require verification of the user's identity by default, which is not limited in this application.

[0433] Optionally, identity authentication methods may include but are not limited to: face recognition, fingerprint recognition, voiceprint recognition, password matching, etc.

[0434] After receiving the vehicle information of vehicle 100, key information of the first digital vehicle key, and the first control instruction from electronic device 300, electronic device 200 can determine whether electronic device 200 has applied for the digital vehicle key of vehicle 100 based on the vehicle information of vehicle 100. For example, electronic device 200 determines that electronic device 200 has applied for the second digital vehicle key of vehicle 100. If the second digital vehicle key and the first digital vehicle key are of the same key type, electronic device 300 can encrypt the first control instruction based on the second digital vehicle key to obtain an encrypted first control instruction. Electronic device 200 then transmits the encrypted first control instruction and the device information of electronic device 200 to vehicle 100 via Bluetooth. After receiving the encrypted first control instruction and the device information of electronic device 200, vehicle 100 can obtain the second digital vehicle key based on the device information of electronic device 200, decrypt the encrypted first control instruction based on the second digital vehicle key to obtain the first control instruction, and execute the first control instruction, for example, to unlock vehicle 100. In this way, electronic device 300 controls vehicle 100 through electronic device 200.

[0435] Optionally, in some embodiments, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control instruction sent by the electronic device 300, the electronic device 200 may also verify the user's identity and, if the identity verification is successful, perform subsequent operations. This improves the security of the electronic device 200 controlling the vehicle 100 via the digital vehicle key.

[0436] Optionally, before the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300, the electronic device 200 may receive a user operation to enable the identity verification function. After the identity verification function is enabled, the electronic device 200 may verify the user's identity after receiving the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300. In other embodiments, if the identity verification function is disabled, the electronic device 200 may not verify the user's identity after receiving the vehicle information of the vehicle 100, the key information of the first digital vehicle key, and the first control command sent by the electronic device 300.

[0437] Optionally, the electronic device 200 may also require verification of the user's identity by default, which is not limited in this application.

[0438] Optionally, identity authentication methods may include but are not limited to: face recognition, fingerprint recognition, voiceprint recognition, password matching, etc.

[0439] Optionally, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, if the electronic device 200 needs to verify the user's identity, the electronic device 200 and the electronic device 300 have established a trusted relationship, and the electronic device 200 can also verify the user's identity through the electronic device 300.

[0440] After the vehicle 100 executes the first control instruction, the vehicle 100 may send a feedback message to the electronic device 200 via the Bluetooth connection. The electronic device 200 then sends the feedback message to the electronic device 300 to prompt the user B that the user B has successfully controlled the vehicle 100 through the electronic device 300.

[0441] Optionally, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may display the window 1009 shown in Figure 10G. The window 1009 may include the text "The right front window of the HUA WEIP60 of the HUAWEI M7 has been checked in through "Lisa's HUA WEIP60"". The window 1009 is used to prompt the user that user B has successfully controlled the vehicle 100 through the electronic device 200.

[0442] Optionally, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may also display the user interface shown in Figure 10H. The user interface shown in Figure 10H displays a card 7812. Card 7812 is similar to card 1005, except that the display format of the window open / close option is changed in card 7812 to prompt the user that the right front window of the current vehicle 100 is open.

[0443] In some embodiments, after the electronic device 300 receives a user input operation for the window open / close option on the card 1005, and if a Bluetooth connection is established between the electronic device 300 and the vehicle 100, the electronic device 300 can directly control the vehicle 100 based on the first digital vehicle key obtained by the application. Specifically, the electronic device 300 can encrypt the first control instruction based on the first digital vehicle key to obtain an encrypted second control instruction, and then send the encrypted second control instruction and the device information of the electronic device 300 to the vehicle 100 via the Bluetooth connection. After receiving the encrypted second control instruction and the device information of the electronic device 300, the vehicle 100 can obtain the first digital vehicle key based on the device information of the electronic device 300, decrypt the encrypted second control instruction based on the first digital vehicle key to obtain the first control instruction, and execute the first control instruction, for example, to unlock the vehicle 100. In this way, the electronic device 300 can directly control the vehicle 100 using the first digital vehicle key.

[0444] After the vehicle 100 executes the first control instruction, the vehicle 100 may send a feedback message to the electronic device 300 via the Bluetooth connection to prompt the user A that the user A has successfully controlled the vehicle 100 through the electronic device 300 .

[0445] Optionally, after the electronic device 300 receives the feedback message sent by the vehicle 100, the electronic device 300 may display the prompt message 1009 shown in Figure 10I. The prompt message 1009 may include the text "The right front window of the M7 has been opened through "TOM's Mate 50"". The prompt message 1009 is used to prompt the user that user A has successfully controlled the vehicle 100 through the electronic device 300.

[0446] Optionally, the prompt information shown in FIG10I is different from the prompt information shown in FIG10G , thereby notifying the user which device the electronic device 300 uses to control the vehicle 100. In other embodiments, the prompt information shown in FIG10H and the prompt information shown in FIG10F may also be the same, and this application does not limit this.

[0447] In some embodiments, after the electronic device 300 can receive the user's input operation for the window opening / closing option, the electronic device 300 has not established a communication connection with the electronic device 200, and the electronic device 300 cannot control the vehicle 100 through the electronic device 200. In this case, the electronic device 300 can display the prompt message 1010 shown in Figure 10J, which is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0448] In some embodiments, after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 200 does not establish a Bluetooth connection with the vehicle 100, or after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 300 determines that the electronic device 300 has not applied for the digital car key of the vehicle 100, or after the electronic device 200 receives the vehicle information of the vehicle 100, the key information of the first digital car key and the first control instruction sent by the electronic device 300, the electronic device 200 determines that the digital car key of the vehicle 100 applied for by the electronic device 200 is different from the type of the digital car key of the vehicle 100 applied for by the electronic device 300, the electronic device 200 may send a feedback message to the electronic device 300, which is used to indicate that the vehicle 100 cannot be controlled at present. For example, after the electronic device 300 receives the feedback message sent by the electronic device 200, the electronic device 300 may also display the prompt message 1010 shown in FIG10J. The prompt message 1010 is used to prompt the user that the vehicle 100 is currently unable to be controlled.

[0449] FIG11 shows a schematic diagram of another electronic device 300 controlling a vehicle 100 via the electronic device 200 .

[0450] S1101. The electronic device 200 displays a first user interface, which includes a first option.

[0451] For example, the first user interface may be the user interface 790 shown in FIG. 10A , and the first option may be the credibility authentication option shown in the user interface 790 .

[0452] S1102: The electronic device 200 receives a user operation on a first option.

[0453] For example, the electronic device 200 may receive a user input operation (eg, a single click) for a credibility authentication option shown in the user interface 790 to establish a trusted relationship with the electronic device 300 .

[0454] Optionally, the user's input operation on the credibility authentication option shown in the user interface 790 may also be referred to as a second user operation.

[0455] In this way, when the electronic device 200 has not established a trusted relationship with the electronic device 300 , the electronic device 200 can proactively initiate the establishment of a trusted relationship with the electronic device 300 .

[0456] S1103 . In response to a user operation, the electronic device 200 displays device identifications of multiple devices, including the device identification of the electronic device 300 .

[0457] In response to user operations, the electronic device 200 can discover nearby devices and display device identifications of multiple devices, including the device identification of the electronic device 300. For example, the device identification of the electronic device 300 can be "Lisa's HUA WEIP60".

[0458] Optionally, before the electronic device 200 displays the device identifications of multiple devices, the electronic device 200 may display a prompt message, which is used to instruct the user to turn on the Bluetooth of the electronic device 200 and turn on the Bluetooth of other devices that need to establish a trusted relationship with the electronic device 200, so that the electronic device 200 can discover other devices near the electronic device 200.

[0459] S1104 : The electronic device 200 receives the user's input operation for the device identification of the electronic device 300 .

[0460] After the electronic device 200 displays the device identifications of multiple devices, the electronic device 300 may receive an input operation from the user for the device identification of the electronic device 200 and actively establish a trusted relationship with the electronic device 300 .

[0461] For example, the electronic device 200 may receive a user input operation for the device identifier “Lisa's HUA WEIP60” and proactively establish a trusted relationship with the electronic device 300 .

[0462] S1105 : The electronic device 200 sends a request to the electronic device 300 to establish a trusted relationship.

[0463] In response to the user's input operation for the device identification of the electronic device 300 , the electronic device 200 may send a request to establish a trusted relationship to the electronic device 300 .

[0464] Optionally, the request to establish a trusted relationship may also be referred to as a request to establish a trusted connection.

[0465] S1106. In response to the request to establish a trusted relationship, the electronic device 300 may display prompt information.

[0466] The prompt information is used to indicate to the electronic device 300 that the electronic device 200 requests to establish a trusted relationship with the electronic device 300 .

[0467] Exemplarily, the prompt information may be the window 1006 shown in FIG. 10D .

[0468] Optionally, the window 1006 shown in FIG. 10D may also be referred to as the first prompt information.

[0469] S1107: The electronic device 300 receives the user's confirmation operation for establishing a trusted relationship.

[0470] For example, the electronic device 300 may receive a user input operation (eg, a single click) for the Continue option in the window 1006 shown in FIG. 10D . In response to the user input operation, the electronic device 300 confirms the establishment of the trusted relationship.

[0471] Optionally, the Continue option in the window 1006 shown in FIG. 10D may also be referred to as a second option.

[0472] S1108. The electronic device 300 sends a message to the electronic device 200 to confirm the establishment of the trusted relationship.

[0473] S1109 : Electronic device 200 and electronic device 300 establish a trusted relationship.

[0474] Optionally, the message confirming establishment of a trusted relationship may also be referred to as a message confirming establishment of a trusted connection.

[0475] In response to the user's operation of confirming the establishment of the trusted relationship, the electronic device 300 may send a message confirming the establishment of the trusted relationship to the electronic device 200 to indicate to the electronic device 200 that the electronic device 300 has confirmed the establishment of the trusted relationship.

[0476] After the electronic device 200 receives the message sent by the electronic device 300 confirming the establishment of the trusted relationship, the electronic device 200 may establish a trusted relationship with the electronic device 300 .

[0477] The electronic device 200 and the electronic device 300 may establish a trusted relationship in the following manners, but not limited to the following.

[0478] Method 1: Electronic device 200 can obtain parameter information of electronic device 200. The parameter information of electronic device 200 may include, but is not limited to, one or more of the following: a device identifier of electronic device 200, a device type of electronic device 200, a first random number, etc. The first random number is used by electronic device 200 and electronic device 300 to generate a trusted credential. Electronic device 200 also needs to send the parameter information of electronic device 200 to electronic device 300. After receiving the parameter information of electronic device 200 sent by electronic device 200, electronic device 300 saves the parameter information of electronic device 200 and obtains the parameter information of electronic device 300. Thereafter, electronic device 300 sends the parameter information of electronic device 300 to electronic device 200. The parameter information of electronic device 300 may include, but is not limited to, one or more of the following: a device identifier of electronic device 300, a device type of electronic device 300, a second random number, etc. The second random number is also used by electronic device 200 and electronic device 300 to generate a trusted credential. After the electronic device 200 and the electronic device 300 obtain the first random number and the second random number, the electronic device 200 can generate a second trusted credential based on the first random number and the second random number, and the electronic device 300 can generate a first trusted credential based on the first random number and the second random number, and save the first trusted credential and the second trusted credential. The trusted credential is used by the electronic device 200 and the electronic device 300 to verify whether the two parties are trusted devices. Optionally, after the electronic device 300 generates the trusted credential based on the first random number and the second random number, the electronic device 300 can send a feedback message to the electronic device 200, which is used to indicate to the electronic device 300 that the electronic device 200 has generated a trusted credential.

[0479] In other embodiments, the electronic device 300 may not provide the parameter information of the electronic device 300 , and the electronic device 200 and the electronic device 300 may only generate a trusted credential based on the first random number, and this application does not limit this.

[0480] After the electronic device 200 and the electronic device 300 both save the first trusted credential and the second trusted credential, the electronic device 200 and the electronic device 300 may determine that both are trusted devices based on the first trusted credential and the second trusted credential.

[0481] In some embodiments, the first trusted credential and the second trusted credential are time-limited. If the length of time that electronic device 200 stores the first trusted credential and the length of time that electronic device 300 stores the second trusted credential exceed the first length of time, electronic device 200 and electronic device 300 can delete the first trusted credential and the second trusted credential, and re-determine a new trusted credential according to method one, and re-establish the trusted relationship between electronic device 200 and electronic device 300.

[0482] Method 2: Electronic device 200 can obtain device information of electronic device 200. The device information of electronic device 200 may include, but is not limited to, one or more of the following: the device identification of electronic device 200, the device type of electronic device 200, etc. Electronic device 200 also needs to send the device information of electronic device 200 to electronic device 300. After receiving the device information of electronic device 200 sent by electronic device 200, electronic device 300 saves the device information of electronic device 200. Based on the device information of electronic device 200, electronic device 300 can determine that electronic device 200 is a trusted device. Electronic device 300 also needs to obtain device information of electronic device 300. The device information of electronic device 300 may include, but is not limited to, one or more of the following: the device identification of electronic device 300, the device type of electronic device 300, etc. Electronic device 300 also needs to send the device information of electronic device 300 to electronic device 200. After receiving the device information of electronic device 300 sent by electronic device 300, electronic device 200 saves the device information of electronic device 300. Based on the device information of electronic device 300, electronic device 200 can determine that electronic device 300 is a trusted device.

[0483] Not limited to the above methods, the electronic device 200 and the electronic device 300 can also establish a trusted relationship based on other methods, which is not limited in this application.

[0484] Optionally, the electronic device 300 may proactively initiate the establishment of a trusted relationship with the electronic device 200 .

[0485] Optionally, in some embodiments, the user accounts logged into the electronic device 200 and the electronic device 300 are different, but the first user account and the second user account are associated with each other, and the relationship between the two devices can also be deemed to be untrusted. The two devices still need to establish a trusted connection through S1101-S1109.

[0486] S1110 : The electronic device 300 controls the vehicle 100 based on the digital vehicle key.

[0487] After the electronic device 200 and the electronic device 300 save the first trusted credential and the second trusted credential, when the electronic device 300 establishes a Bluetooth connection with the vehicle 100, the electronic device 300 can directly control the vehicle 100 through the first digital car key. For details, please refer to the description in the embodiment of Figure 9A, and this application will not go into details here.

[0488] When the electronic device 200 has established a Bluetooth connection with the vehicle 100, the electronic device 300 cannot establish a Bluetooth connection with the vehicle 100, and the electronic device 300 cannot directly control the vehicle 100 through the first digital car key. However, the electronic device 200 and the electronic device 300 have established a trusted relationship through S1101-S1108, and the electronic device 200 and the electronic device 300 are trusted devices. Then the electronic device 200 can control the vehicle 100 through the electronic device 300. Specifically, it is similar to the description in the S905-S919 embodiment of the embodiment of Figure 9A. Specifically, reference can be made to the description in the S905-S919 embodiment of Figure 9A, and this application will not repeat them here.

[0489] However, the present application differs from the S905-S919 embodiments in the following ways.

[0490] If the electronic device 200 and the electronic device 300 establish a trusted relationship through the above-mentioned method 1, the present application differs from the embodiments S905-S919 in the following ways.

[0491] Difference 1: In S905, in addition to sending the vehicle information of the vehicle 100 and the key information of the first digital vehicle key to the electronic device 200, the electronic device 300 also needs to send the first trusted credential and the device information of the electronic device 300 to the electronic device 300. The first trusted credential and the device information of the electronic device 300 are used by the electronic device 300 to verify whether the electronic device 200 is a trusted device.

[0492] Difference 2: Before executing S910 , the electronic device 200 can obtain the second trusted credential stored in the electronic device 200 based on the device information of the electronic device 300 .

[0493] If the second trusted credential stored in electronic device 200 is the same as the first trusted credential sent by electronic device 300 or meets a preset condition, electronic device 200 can determine that electronic device 300 is a trusted device and send a verification pass message to electronic device 300. After receiving the verification pass message, electronic device 300 can control vehicle 100 through electronic device 200.

[0494] When the second trusted credential stored in the electronic device 200 is different from the first trusted credential sent by the electronic device 300 or does not meet the preset conditions, the electronic device 200 can determine that the electronic device 300 is an untrusted device. Then the electronic device 200 can send a verification failure message to the electronic device 300, and the electronic device 300 cannot control the vehicle 100 through the electronic device 200.

[0495] If the electronic device 200 and the electronic device 300 establish a trusted relationship through the above-mentioned method 2, the present application differs from the embodiments S905-S919 in the following ways.

[0496] Difference 1: In S905, in addition to sending the vehicle information of the vehicle 100 and the key information of the first digital vehicle key to the electronic device 200, the electronic device 300 also needs to send the device information of the electronic device 300 to the electronic device 300. The device information of the electronic device 300 is used by the electronic device 300 to verify whether the electronic device 200 is a trusted device.

[0497] When the electronic device 200 determines that the electronic device 300 is a trusted device based on the device information of the electronic device 300, the electronic device 200 may send a verification pass message to the electronic device 300. After receiving the verification pass message, the electronic device 300 may control the vehicle 100 through the electronic device 200.

[0498] If electronic device 200 determines that electronic device 300 is not a trusted device based on the device information of electronic device 300, for example, electronic device 200 and electronic device 300 have not established a trusted relationship, and electronic device 200 does not store the device information of electronic device 300, electronic device 200 cannot confirm that electronic device 300 is a trusted device. In this case, electronic device 200 can send a verification failure message to electronic device 300, and electronic device 300 cannot control vehicle 100 through electronic device 200.

[0499] Optionally, when the electronic device 200 determines that the electronic device 300 is not a trusted device, the electronic device 300 may also prompt the user to negotiate and determine a trusted relationship through S1101-S1108. After that, after the electronic device 300 and the electronic device 200 establish a trusted relationship, the electronic device 300 may control the vehicle 100 through the electronic device 200.

[0500] Multiple users' different devices control the vehicle 100

[0501] User A owns electronic device 200, and user B owns electronic device 300. User A and user B approach a vehicle simultaneously. If electronic device 300 has first established a Bluetooth connection with vehicle 100, electronic device 300 will no longer be able to establish a Bluetooth connection with vehicle 100. Electronic device 300 will no longer be able to control vehicle 100 using the digital car key. In this case, after establishing a Bluetooth connection with electronic device 200, vehicle 100 can periodically or irregularly broadcast Bluetooth signals so that other devices near vehicle 100 can discover vehicle 100. For example, electronic device 300 receives and responds to the Bluetooth broadcast sent by vehicle 100, sending a request to establish a Bluetooth connection to vehicle 100. In response to the request to establish a Bluetooth connection, vehicle 100 can send a request to disconnect the Bluetooth connection to electronic device 200. After receiving the request to disconnect the Bluetooth connection and disconnecting the Bluetooth connection with vehicle 100, vehicle 100 can then establish a Bluetooth connection with electronic device 300. Electronic device 300 can then control vehicle 100 using the digital car key.

[0502] 12A-12B show a schematic diagram of an electronic device 300 controlling a vehicle 100 via a Bluetooth connection.

[0503] The vehicle 100 disconnects the Bluetooth connection with the electronic device 200 and establishes a Bluetooth connection with the electronic device 300 ( FIG. 12A-FIG . 12B ).

[0504] First, the electronic device 200 establishes a Bluetooth connection with the vehicle 100. However, the vehicle 100 still periodically / irregularly sends Bluetooth broadcasts so that other devices near the vehicle 100 can discover the vehicle 100. For example, the electronic device 300 can receive the Bluetooth broadcasts sent by the vehicle 100.

[0505] Referring to the description in the embodiment of Figure 10A, the electronic device 300 can receive the user's input operation for the window opening / closing option on the card 1005 displayed in the user interface shown in Figure 10E. In response to the user's input operation, when the electronic device 300 receives the Bluetooth broadcast sent by the vehicle 100, the electronic device 300 can send a request to establish a Bluetooth connection to the vehicle 100.

[0506] In response to the Bluetooth connection establishment request sent by the electronic device 300, the vehicle 100 determines whether a Bluetooth connection has been established with the other device. If no Bluetooth connection has been established with the other device, the vehicle 100 may directly establish a Bluetooth connection with the electronic device 300. If a Bluetooth connection has been established with the other device, the vehicle 100 may request to disconnect the Bluetooth connection with the other device.

[0507] For example, when the vehicle 100 determines that a Bluetooth connection is established with the electronic device 200 , the vehicle 100 may send a request to disconnect the Bluetooth connection to the electronic device 200 .

[0508] In response to the Bluetooth disconnect request sent by vehicle 100, electronic device 200 may display prompt message 1201 shown in FIG12A . The prompt message may include "TOM's Mate 50 requests to connect to the Bluetooth of the QNEX M7. Do you want to disconnect the Bluetooth connection with the QNEX M7?" Prompt message 1201 also includes confirmation and cancellation options. The user can confirm the connection between electronic device 200 and vehicle 100, or cancel the connection to maintain the Bluetooth connection.

[0509] For example, as shown in FIG12A , the electronic device 200 may receive a user input operation (eg, a single click) for a confirmation option in the prompt message 1201 . In response to the user's input operation, the electronic device 200 may disconnect the Bluetooth connection with the vehicle 100 .

[0510] After receiving the Bluetooth connection establishment request sent by the electronic device 300 , in response to disconnecting the Bluetooth connection with the vehicle 100 , the vehicle 100 may establish a Bluetooth connection with the electronic device 300 .

[0511] Optionally, after the electronic device 300 establishes a Bluetooth connection with the vehicle 100 , the electronic device 300 may display a prompt message 1202 as shown in FIG. 12B , which is used to prompt the user that the electronic device 300 has established a Bluetooth connection with the vehicle 100 .

[0512] After the electronic device 300 establishes a Bluetooth connection with the vehicle 100 and the electronic device 300 applies for the digital key of the vehicle 100, in response to a user input operation for the window open / close option on the card 1005 displayed in the user interface 1004 shown in FIG10E , the electronic device 300 may generate a first control instruction and send the first control instruction to the vehicle 100. The vehicle 100 may execute the first control instruction and return the execution result to the electronic device 300.

[0513] After receiving the execution result sent by the vehicle 100 , the electronic device 300 may display a prompt message 1009 as shown in FIG10H . The prompt message 1009 is used to prompt the user that the right front window of the vehicle 100 has been opened through the electronic device 300 .

[0514] In some embodiments, if vehicle 100 can only establish a Bluetooth connection with one device at a time, if electronic device 200 establishes a Bluetooth connection with vehicle 100, electronic device 300 cannot connect to vehicle 100 via Bluetooth. Electronic device 300 also cannot control vehicle 100 via the Bluetooth car key. Optionally, after establishing a Bluetooth connection with electronic device 200, vehicle 100 may periodically or sporadically send Bluetooth broadcasts so that other devices near vehicle 100 can discover vehicle 100. For example, electronic device 300 receives and responds to the Bluetooth broadcasts sent by vehicle 100, sending a Bluetooth connection establishment request to vehicle 100. In response to the Bluetooth connection establishment request, vehicle 100 may send a Bluetooth connection disconnection request to electronic device 200. After receiving the Bluetooth connection disconnection request and disconnecting the Bluetooth connection with vehicle 100, vehicle 100 may establish a Bluetooth connection with electronic device 300. Electronic device 300 can then control vehicle 100 via the digital car key.
