Description

Technical Field

[0001] The present application relates to the field of digital key technology, and more specifically, to a digital key connection method, device, vehicle, and storage medium in the vehicle field. Background Art

[0002] In the current development of intelligent vehicles, digital key technology has become an important configuration trend to enhance user experience and vehicle safety. Digital keys are more convenient than traditional keys. Car owners can flexibly set key sharing permissions and grant vehicle access rights to family, friends, etc., greatly improving the flexibility and sharing of vehicle use. In terms of digital key connection mode selection, there are two working modes, single connection and multi-connection. In single connection mode, the vehicle only supports the connection of one digital key at a time, which can easily hinder the normal connection of the key in scenarios where multiple people share the key in the vehicle; in multi-connection mode, the vehicle will continuously scan and receive signals, which will cause unnecessary power loss when the key is not shared. Summary of the Invention

[0003] The present application provides a digital key connection method, device, vehicle and storage medium, which can solve the technical problem in related technologies that the digital key function is difficult to adapt to changes in user needs.

[0004] In a first aspect, a method for connecting a digital key is provided, the method comprising:

[0005] In response to a user-triggered operation on a digital key, determining the number of current digital keys based on the operation result;

[0006] Determining a target digital key connection mode corresponding to the vehicle according to the number of the digital keys, the target digital key connection mode being a single connection mode or a multi-connection mode, and different digital key connection modes correspond to different broadcasting methods of key connection broadcasts;

[0007] Determine whether the current digital key connection mode of the above-mentioned vehicle is the above-mentioned target digital key connection mode, and adjust the above-mentioned vehicle to the above-mentioned target digital key connection mode if the above-mentioned current digital key connection mode is different from the above-mentioned target digital key connection mode, so that the above-mentioned vehicle is connected to the digital key according to the above-mentioned target digital key connection mode.

[0008] The beneficial effects brought about by the technical solution of the first aspect above include at least: the user can timely detect the change in the number of digital keys in the vehicle through the operation of the digital key; then, based on the number of digital keys after the change, if there are multiple digital keys, it means that the current vehicle still needs multiple key connections, and if there is only one digital key, it means that the current vehicle only needs a single key connection. Based on this, it is accurately judged whether the target digital key connection mode required by the vehicle is a single connection mode or a multi-connection mode; then it is verified whether the digital key connection mode used by the vehicle at this time meets the current needs, and if it does not meet the needs, the vehicle is adjusted to the target digital key connection mode currently required, so that the vehicle is connected to the legal digital key according to the adjusted digital key connection mode. In this way, by accurately identifying the key connection needs of the vehicle and dynamically adjusting the digital key connection mode in the vehicle, it is possible to accurately capture user needs and automatically adjust the vehicle to meet user needs. Under the premise of ensuring the availability and flexibility of the key sharing function, unnecessary power consumption is avoided, thereby improving the performance of the digital key system and user experience.

[0009] In some possible implementations, the above-mentioned determination of the target digital key connection mode corresponding to the vehicle based on the number of the above-mentioned digital keys includes: if there is only one digital key at present, determining that the target digital key connection mode corresponding to the above-mentioned vehicle is the above-mentioned single connection mode; if there are multiple digital keys at present, determining that the target digital key connection mode corresponding to the above-mentioned vehicle is the above-mentioned multi-connection mode.

[0010] Through the technical solutions in the above possible implementation methods, if it is determined that there is only one legal digital key in the current vehicle, it means that the vehicle only has a connection requirement for a single digital key, that is, the vehicle needs a single connection mode at this time to reduce unnecessary power consumption waste; if it is determined that there are multiple legal digital keys in the current vehicle, it means that the vehicle has a connection requirement for multiple digital keys, that is, the vehicle needs a multi-connection mode at this time to realize the flexible sharing of digital key functions.

[0011] In some possible implementations, the single-connection mode adopts a single-channel broadcasting method, and the multi-connection mode adopts a multi-channel broadcasting method.

[0012] Through the technical solutions in the above possible implementation methods, the vehicle adopts different broadcast methods for different digital key connection modes. The single-connection mode uses a single-channel broadcast method, and the multi-connection mode uses a multi-channel broadcast method to realize the control of the digital key connection function.

[0013] In some possible implementations, the above-mentioned adjusting the vehicle to the above-mentioned target digital key connection mode when the above-mentioned current digital key connection mode is different from the above-mentioned target digital key connection mode includes: when the above-mentioned current digital key connection mode is different from the above-mentioned target digital key connection mode, turning off the key connection broadcast in the above-mentioned vehicle and reopening the above-mentioned key connection broadcast according to the key connection broadcast method corresponding to the above-mentioned target digital key connection mode.

[0014] Through the technical solutions in the above possible implementation methods, the digital key connection mode of the vehicle is switched by restarting the key connection broadcast, so that the vehicle can connect the digital key according to the target digital key connection mode.

[0015] In some possible implementations, when the above-mentioned vehicle is in the above-mentioned single connection mode, the above-mentioned method also includes: when a digital key device corresponding to the digital key is monitored, establishing a communication link with the above-mentioned digital key device, and continuously locating the above-mentioned digital key device; when the above-mentioned digital key device enters the driving intention recognition area corresponding to the above-mentioned vehicle, unlocking is performed in response to the vehicle unlocking signal sent by the above-mentioned digital key device through the above-mentioned communication link, and logging into the multimedia system in the above-mentioned vehicle according to the user identity information corresponding to the above-mentioned digital key.

[0016] Through the technical solutions in the above possible implementations, when a user approaches a vehicle holding a digital key, the vehicle can directly establish a connection with the digital key device and accurately determine the user's entry and driving intentions by locating the digital key device. Once the user's driving intention is determined, the vehicle can also automatically receive a vehicle unlock signal triggered by the digital key device, achieving contactless unlocking and logging the user account associated with the digital key into the multimedia system, enhancing the user's driving experience.

[0017] In some possible implementations, after the digital key device corresponding to the digital key is monitored, the method further includes: controlling the multimedia system to enter a standby state; after the digital key device enters the driving intention recognition area corresponding to the vehicle, the method further includes: pre-sending the user identity information corresponding to the digital key to the multimedia system.

[0018] Through the technical solutions in the above possible implementation methods, when the digital key approaches the vehicle, the vehicle can control the multimedia system to enter the standby state, so that the screen can be quickly lit up when the user gets on the vehicle, making it convenient for the user to interact; when the driving intention of the digital key user is identified, the identity account information of the user can be sent to the multimedia system in advance, so that the multimedia system can quickly and automatically log in to the user account when the user gets on the vehicle, making it convenient for the user to operate under his or her own account.

[0019] In some possible implementations, when the above-mentioned vehicle is in the above-mentioned multi-connection mode, the above-mentioned method also includes: when digital key devices corresponding to multiple digital keys are monitored, establishing a communication link with each digital key device and continuously locating each digital key device; when at least one digital key device enters the driving intention recognition area corresponding to the above-mentioned vehicle, unlocking is performed in response to the vehicle unlocking signal sent by at least one digital key device through the above-mentioned communication link; determining the target device and target digital key corresponding to the driver, and logging into the multimedia system in the above-mentioned vehicle according to the user identity information corresponding to the above-mentioned target digital key.

[0020] Through the technical solutions in the above possible implementations, in multi-connection mode, when a digital key approaches the vehicle, the vehicle can establish connections with all recognized digital key devices and accurately determine the boarding and driving intentions of each user by locating the digital key device. After the vehicle is unlocked without any sensor, the device and digital key corresponding to the driver can be further determined, and the corresponding user account can be logged into the multimedia system, improving the accuracy of driver recognition.

[0021] In some possible implementations, the above-mentioned determination of the target device and target digital key corresponding to the driver includes: when only one digital key device enters the driving intention recognition area corresponding to the above-mentioned vehicle, determining that the digital key device in the above-mentioned driving intention recognition area is the target device corresponding to the driver and determining the target digital key corresponding to the above-mentioned target device; when multiple digital key devices enter the driving intention recognition area corresponding to the above-mentioned vehicle, obtaining the precise positioning of each digital key device in the vehicle, and determining that the digital key device in the main driving area is the target device corresponding to the driver based on the precise positioning of each digital key device in the vehicle and determining the target digital key corresponding to the above-mentioned target device.

[0022] Through the technical solutions in the above-mentioned possible implementation methods, when determining the driver's identity, if only one digital key device enters the driving intention recognition area, the driver can be directly confirmed; but if multiple digital key devices are identified as entering the driving intention recognition area, the identity of the main driver can be further determined based on the more precise positioning of the digital key device in the car after the user gets in the car, thereby achieving accurate login of the driver's account on the multimedia system.

[0023] In some possible implementations, the above method also includes: when a digital key device corresponding to at least one digital key is monitored, adjusting the broadcast period of the key connection broadcast according to the distance between each digital key device and the above vehicle, and the above broadcast period is positively correlated with the above distance; and / or, determining the broadcast period of the above key connection broadcast according to the current digital key connection mode, the first broadcast period corresponding to the above single connection mode is longer than the second broadcast period corresponding to the above multi-connection mode.

[0024] Through the technical solutions in the above possible implementations, when a vehicle recognizes a digital key device, the broadcast period can be gradually shortened as the digital key device approaches, saving unnecessary energy while ensuring efficient digital key connection when the user is close to the vehicle. Similarly, the vehicle can also adaptively select the broadcast period based on different connection modes, similarly reducing energy consumption and improving key connection performance.

[0025] In some possible implementations, the method further includes: starting the key connection broadcast when the vehicle power is off, or when the vehicle power is on and the door status changes; and turning off the key connection broadcast when the vehicle power is on and the vehicle speed reaches a preset threshold.

[0026] Through the technical solutions in the above possible implementation methods, the key connection broadcast can be activated when the vehicle is in the off state or when the door state changes after the vehicle is started, so as to be ready for digital key connection at any time; if the vehicle has been started and is in driving state, it means that there is almost no need to connect the digital key at this time. In this case, the key connection broadcast can be turned off in time to reduce power consumption.

[0027] In some possible implementations, the communication type of the key connection broadcast includes at least one of Bluetooth communication and ultra-wideband communication.

[0028] Through the technical solutions in the above possible implementation methods, the vehicle can realize the digital key function through a variety of short-range communication methods.

[0029] In some possible implementations, the operation triggered on the digital key includes at least one of a digital key sharing operation and a digital key revocation operation.

[0030] Through the technical solutions in the above possible implementation methods, users can perform various operations such as sharing, authorization and revocation of digital keys to meet the diverse needs of users.

[0032] a key quantity determination module, configured to respond to an operation triggered by a user on a digital key and determine the number of current digital keys based on the result of the operation;

[0033] a connection mode determination module, configured to determine a target digital key connection mode corresponding to the vehicle based on the number of the digital keys, wherein the target digital key connection mode is a single connection mode or a multi-connection mode, and different digital key connection modes correspond to different key connection broadcast modes;

[0034] The connection mode switching module is used to determine whether the current digital key connection mode of the above-mentioned vehicle is the above-mentioned target digital key connection mode, and to adjust the above-mentioned vehicle to the above-mentioned target digital key connection mode when the above-mentioned current digital key connection mode is different from the above-mentioned target digital key connection mode, so that the above-mentioned vehicle is connected to the digital key according to the above-mentioned target digital key connection mode.

[0044] To make the features and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0045] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. And in the description of the embodiments of the present application, unless otherwise indicated, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a way to describe the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" refers to two or more than two.

[0046] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0047] Current digital key technology primarily relies on the integration of modern wireless communications, such as Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB), with precise positioning technologies, enabling users to conveniently control a range of vehicle functions, including unlocking, starting, and locating, through their smartphones or other mobile devices. Compared to traditional physical radio frequency keys (such as remote controls or smart cards), one of the core advantages of digital keys lies in their convenient sharing capability. This means that car owners can securely authorize long-term or temporary digital key credentials to other users, such as family members, friends, or designated drivers, through a dedicated app running on their mobile device or a key management interface integrated into the phone's operating system (such as a wallet), enabling remote and refined access rights.

[0048] However, to enable near-field automatic sensing, such as contactless unlocking, digital keys rely on near-field communication, which requires a constant or frequent connection between the mobile device and the vehicle, ensuring readiness for data exchange and response to vehicle commands. Near-field connection modes are typically configurable as either single-connection or multi-connection. In single-connection mode, the vehicle is only allowed to establish one valid connection channel at a time. This means that once a valid digital key successfully connects and occupies that single channel, any other mobile device holding a valid digital key credential will be blocked or denied access when attempting to connect until the current connection is actively disconnected or the channel times out. This exclusivity limits the practicality of digital key sharing. To further address the channel congestion associated with single-connection mode, multi-connection mode has emerged, allowing the vehicle to establish and maintain communication connections with multiple authorized mobile devices simultaneously. However, because near-field connections require the vehicle to periodically broadcast or listen to maintain link activity, this mode significantly increases unnecessary energy consumption in non-shared key scenarios.

[0049] Therefore, an embodiment of the present application provides a digital key connection method to solve the technical problem that the above-mentioned digital key function is difficult to adapt to changes in user needs.

[0050] See also Figure 1 , Figure 1 An exemplary system architecture diagram of a digital key connection method provided in an embodiment of the present application.

[0051] like Figure 1 As shown, the system architecture may include a vehicle 101, a network 102, and a mobile terminal 103. The network 102 is used to provide a medium for a communication link between the vehicle 101 and the mobile terminal 103. The network 102 may include various types of wireless communication links, such as a near field communication link (NFC), an ultra-wideband communication link (UWB), a Bluetooth communication link, a wireless fidelity (Wi-Fi) communication link, or a microwave communication link.

[0052] The vehicle 101 can interact with the mobile terminal 103 via the network 102 to receive messages from the mobile terminal 103 or send messages to the mobile terminal 103. Alternatively, the vehicle 101 can interact with the mobile terminal 103 via the network 102 to receive messages or data sent to the mobile terminal 103 by other users. It should be noted that the mobile terminal 103 can be hardware or software. When the mobile terminal 103 is hardware, it can be a smartphone, a smartwatch, a smart tablet, a laptop computer, etc. When the mobile terminal 103 is software, it can be implemented as a collection of multiple application software or software modules, or as a single application software or software module, without specific limitation herein.

[0053] In an embodiment of the present application, vehicle 101 first responds to the operation triggered by the user on the digital key, and determines the number of current digital keys based on the operation result; further, vehicle 101 determines the target digital key connection mode corresponding to the vehicle according to the number of digital keys, and the target digital key connection mode is a single connection mode or a multi-connection mode, and different digital key connection modes correspond to different key connection broadcasting methods; based on this, vehicle 101 can continue to determine whether the current digital key connection mode of the vehicle is the target digital key connection mode, and adjust the vehicle to the target digital key connection mode when the current digital key connection mode is different from the target digital key connection mode, so that the vehicle is connected to the digital key according to the target digital key connection mode.

[0054] When the vehicle 101 executes the above steps, the various control logics therein can be implemented by specific hardware devices integrated in the vehicle, such as a digital key main module that specifically provides digital key functions, or a vehicle-mounted management module that provides various vehicle functions. In addition, in addition to the exemplary vehicle 101 in the embodiment of the present application, the digital key connection method can also be executed on electronic devices such as smart door locks and computers. According to implementation needs, the system architecture can include any electronic device with corresponding processing capabilities to execute the digital key connection method. The vehicle 101 that executes the digital key connection method provided in the embodiment of the present application should not limit the electronic device that implements the digital key connection method.

[0055] It should be understood that Figure 1 The number of vehicles, networks and mobile terminals is only illustrative and can be any number of vehicles, networks and mobile terminals according to implementation requirements.

[0056] See also Figure 2 , Figure 2This is a flowchart of a digital key connection method provided in an embodiment of the present application. The execution subject of this embodiment of the present application can be a vehicle executing the digital key connection, a processor in a vehicle executing the digital key connection method, or a digital key connection service in a vehicle executing the digital key connection method. For ease of description, the specific execution process of the digital key connection method is described below using the vehicle processor as an example.

[0057] like Figure 2 As shown, the digital key connection method may at least include:

[0058] S202: In response to an operation triggered by a user on a digital key, determine the number of current digital keys based on the operation result.

[0059] Alternatively, relying on current digital key technology, users can trigger various operations on digital keys, such as digital key sharing and digital key revocation, through specific applications on mobile terminals or the digital key function module on the vehicle's central control screen. These operations involve multiple configurations, such as the creation, authorization, identity binding, and unbinding and cancellation of digital key credentials. Car owners can share digital keys with others based on these operations, or cancel authorization of existing digital keys. In order to ensure connection stability and responsiveness when meeting the needs of multi-user sharing, while reducing power consumption when used by a single user, the embodiments of the present application judge changes in user needs based on the user's actual management operations and the existence status of the digital key, thereby dynamically adjusting the vehicle's digital key connection mode to achieve optimal system performance and user experience in different scenarios.

[0060] In an embodiment of the present application, first, when a vehicle user manages a digital key, such as sharing digital key permissions with a third party or actively revoking a shared key authorization, the vehicle can capture the operation event and its operation result data in real time. By parsing the key authorization status change information reflected by the operation result, it is dynamically evaluated whether there are multiple valid digital keys currently bound to the vehicle. For example, when a car owner creates and authorizes a new digital key sharing certificate to relatives and friends, the system will detect that the number of valid keys has changed from a single key (only the owner's key) to multiple keys (owner's key + shared key); conversely, when the owner performs the "retrieve key" operation in the key management list, the system recognizes that the number of valid keys has decreased.

[0061] Specifically, the vehicle maintains a list of currently valid digital keys, which contains the unique identifier of each digital key, the authorization status and the associated user identity information. Whenever the user makes an operation to change the number of digital keys, the result of the operation will be directly reflected in the digital key list, and then by looking up the table, it can be detected whether the number of valid digital keys is multiple. It should be noted that in order to reduce the unnecessary computing power consumption caused by the system judging all digital key operations, the operations triggered by digital keys in this application can only refer to operations that will substantially change the number of valid digital keys.

[0062] S204: Determine a target digital key connection mode corresponding to the vehicle according to the number of digital keys. The target digital key connection mode is a single connection mode or a multi-connection mode. Different digital key connection modes correspond to different broadcasting methods of key connection broadcasts.

[0063] Optionally, based on the above-mentioned judgment conclusion on the number of valid keys, the vehicle can automatically decide the target digital key connection mode to be adopted. The digital key connection mode is divided into single connection mode and multi-connection mode. Different digital key connection modes correspond to different key connection broadcasting methods. Obviously, the power consumption of the single connection mode is lower than that of the multi-connection mode. By dynamically adjusting the connection mode of the digital key, the vehicle power consumption is also more reasonable.

[0064] Specifically, if it is determined that there is only one valid digital key (including cases where no shared keys have been used or all shared keys have been retrieved), the target digital key connection mode is determined to be the relatively lower power single-connection mode. If it is determined that there are two or more valid keys (such as after a shared key), the target mode is determined to be the multi-connection mode that supports multiple keys being connected simultaneously. Each connection mode corresponds to a specific broadcast strategy for key connection broadcasts in the vehicle, that is, the single-connection mode uses a single-channel broadcast method, and the multi-connection mode uses a multi-channel broadcast method.

[0065] In one feasible implementation, vehicles can use at least two short-range communication methods, Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB), to achieve key connection in actual applications. Bluetooth Low Energy (BLE) has the characteristics of low energy consumption and easy deployment, and can establish a stable data transmission channel between the mobile terminal and the vehicle; Ultra-Wideband (UWB) technology uses centimeter-level high-precision positioning capabilities to accurately determine the relative position relationship between the mobile terminal and the vehicle. In a further preferred solution, these two technologies can also be used in conjunction to achieve key connection, thereby enabling the digital key device to quickly unlock, start, lock, and other full-process control of the vehicle.

[0066] In another feasible implementation, the vehicle's factory default digital key connection mode can be a single connection mode. When it is unclear whether the user needs to set up multiple digital keys, priority is given to providing the user with a solution that consumes less energy and has greater information security, thereby improving the vehicle's endurance in the factory default state.

[0067] S206. Determine whether the current digital key connection mode of the vehicle is the target digital key connection mode, and adjust the vehicle to the target digital key connection mode if the current digital key connection mode is different from the target digital key connection mode, so that the vehicle is connected to the digital key according to the target digital key connection mode.

[0068] Optionally, after the vehicle determines the target digital key connection mode to be switched, it compares it with the current real-time connection mode status. If the two are detected to be inconsistent, the connection mode switching process is automatically triggered so that the vehicle can subsequently connect to the digital key according to the target digital key connection mode.

[0069] Specifically, the digital key connection mode switching process involves the coordinated operation of the vehicle's key connection broadcast control unit and associated communication modules. Taking Bluetooth as an example, a mode switch command is first sent to the Bluetooth module controlling key connection broadcast. The Bluetooth module then responds by dynamically reconfiguring broadcast parameters based on the key connection broadcast method corresponding to the target digital key connection mode. For example, when switching from single-connection mode to multi-connection mode, the Bluetooth module switches to multi-channel broadcast, increases the broadcast channel duty cycle, and initializes the multi-device connection pool. Conversely, when switching from multi-connection mode back to single-connection mode, the module also switches back to single-channel broadcast to free up excess connection resources. After the mode adjustment is complete, the vehicle connects to the digital key according to the target digital key connection mode. This dynamic adjustment mechanism allows the vehicle to adapt to the user's actual key usage needs in real time. When the key is not shared, the vehicle maintains single-connection mode, and the Bluetooth module operates in an ultra-low power state, significantly reducing battery energy consumption when the vehicle is parked. Once the user shares the key, the vehicle seamlessly switches to multi-connection mode, ensuring that all shared key holders can connect to the vehicle at any time, ensuring the immediate availability of the key sharing feature. In actual application scenarios, when a family member approaches the vehicle with an authorized digital key, the vehicle's wireless communication module promptly detects the device's connection request and establishes a stable communication connection, allowing it to perform operations such as unlocking and starting the car. At the same time, the owner's digital key remains effectively connected, enabling the simultaneous use of multiple user digital keys. In single-connection mode, when only the owner's key is active, the system significantly reduces the power consumption of the wireless communication module by reducing the broadcast frequency and power, thereby extending the vehicle's battery life.

[0070] In an embodiment of the present application, a digital key connection method is provided, which responds to an operation triggered by a user on a digital key, determines the current number of digital keys based on the operation result; determines a target digital key connection mode corresponding to the vehicle according to the number of digital keys, the target digital key connection mode is a single connection mode or a multi-connection mode, and different digital key connection modes correspond to different key connection broadcasting methods; determines whether the current digital key connection mode of the vehicle is the target digital key connection mode, and adjusts the vehicle to the target digital key connection mode when the current digital key connection mode is different from the target digital key connection mode, so that the vehicle is connected to the digital key according to the target digital key connection mode. Through the user's operation of the digital key, the change in the number of digital keys in the vehicle can be detected in a timely manner; if the number of digital keys after the change is multiple, it means that the current vehicle still needs multiple key connections, and if there is only one digital key, it means that the current vehicle only needs a single key connection. Based on this, it is accurately judged whether the target digital key connection mode required by the vehicle is a single connection mode or a multi-connection mode; then it is verified whether the digital key connection mode used by the vehicle at this time meets the current needs, and if it does not meet the requirements, the vehicle is adjusted to the currently required target digital key connection mode, so that the vehicle can be connected to the legal digital key according to the adjusted digital key connection mode. In this way, by accurately identifying the vehicle's key connection needs and dynamically adjusting the digital key connection mode in the vehicle, it is possible to accurately capture user needs and automatically adjust the vehicle to meet user needs. While ensuring the availability and flexibility of the key sharing function, unnecessary power consumption is avoided, thereby improving the performance of the digital key system and user experience.

[0071] Currently in the field of vehicle driving, users often interact with and control the vehicle based on the multimedia on the in-vehicle display screen. Vehicle users often register their own personal accounts to log in to the multimedia system in order to add their own personalized settings in the car. Relying on the advantage of the digital key's fast and seamless connection with the vehicle, the embodiment of the present application can determine whether the user holding the digital key has the intention to drive when a connectable digital key device appears around the vehicle. If so, the user account is automatically logged into the in-vehicle multimedia system, so that after the driver gets in the car, the in-vehicle display screen will light up directly and log in to his account. At this time, the driver can directly control the vehicle while logged in to his account, thereby improving the driver's driving experience.

[0072] As can be seen from the above embodiments, in single-connection mode, the vehicle will only be connected to one digital key at a time, while in multi-connection mode, the vehicle may be connected to multiple digital keys at the same time. In this embodiment, the multimedia system login process in single-connection mode and multi-connection mode is described separately.

[0073] See also Figure 3 , Figure 3 A flowchart of a digital key login method in a digital key connection method provided in an embodiment of the present application.

[0074] like Figure 3 As shown, when the vehicle is in single connection mode, the digital key registration method in the digital key connection method may at least include:

[0075] S302: When a digital key device corresponding to the digital key is detected, a communication link is established with the digital key device, and the digital key device is continuously located.

[0076] Optionally, see Figure 4 , Figure 4 This is a schematic diagram of the connection range between a digital key and a vehicle provided in an embodiment of the present application. Figure 4 As shown, taking the example of a vehicle using a digital key main module to implement the digital key function, the vehicle also includes a multimedia host that controls the multimedia system. The digital key broadcast range of the vehicle is within a certain distance around the vehicle (for example, 10 meters, 15 meters, etc.), and the vehicle's judgment area for the user's intention to get on the vehicle is within a certain distance near the vehicle body (for example, 1 meter, 2 meters, etc.). Among them, the judgment area for the intention to get on the vehicle can be divided into the main driver's side area as the driving intention recognition area and the co-driver's side area as the co-driver's intention recognition area based on the vehicle's left-hand and right-hand drive characteristics. In addition, the interior space is further divided into the main driver's area, the co-driver's area, and the passenger area. At the same time, the judgment area for the intention to get on the vehicle is smaller than the digital key broadcast range and closer to the vehicle body. Based on such a vehicle architecture, the vehicle can scan the authorized digital key devices within the connectable range around the vehicle in real time through key connection broadcasting.

[0077] In a feasible implementation, in order to accurately locate the user's location, please refer to Figure 4 The specific location of the digital key can be obtained by installing digital key antennas around the vehicle body (for example, on the front left, front right, rear left, and rear right sides of the vehicle). These digital key antennas can use low-power Bluetooth communication, ultra-wideband communication, or a combination of low-power Bluetooth and ultra-wideband communication.

[0078] Furthermore, when a user approaches a vehicle with an authorized digital key device (such as a mobile phone, smart watch, etc.), the digital key antenna detects the wireless signal emitted by the device, and the vehicle establishes a communication link with the digital key device. The strength and duration of the signal during communication are used to determine whether the device is stationary or close, so as to achieve the purpose of continuously locating the digital key device.

[0079] S304. When the digital key device enters the driving intention recognition area corresponding to the vehicle, the vehicle is unlocked in response to the vehicle unlocking signal sent by the digital key device through the communication link, and the multimedia system in the vehicle is logged in according to the user identity information corresponding to the digital key.

[0080] Furthermore, while continuously locating the digital key device, if the vehicle detects the user approaching and entering the driving intention recognition area, it indicates a driving intention. At this point, the digital key device can proactively unlock the vehicle via a vehicle unlock signal sent through the communication link, or the vehicle can unlock the vehicle by identifying the status of the door handle. Once the vehicle is unlocked, it confirms the user's intention to use the vehicle. If the vehicle determines that the user intends to drive, it initiates an automatic account login process, sending the user identity information corresponding to the digital key to the multimedia host, which then uses the user identity information to log into the multimedia system. Once the user identity is logged in, the multimedia system displays personalized information on the vehicle's display based on the user's account settings, including but not limited to the dashboard theme, air conditioning temperature, frequently used navigation locations, and music playlists. The entire process does not require the user to manually enter their account password or click a login button. The total time from detecting the digital key device to completing account login and personalized configuration is also shorter than the traditional manual login process, significantly improving efficiency.

[0081] In addition, users can also pre-set their own exclusive operating interface, so the in-car display screen can directly enter the user's exclusive operating interface after the user takes his seat. The interface layout is dynamically adjusted according to the user's historical interaction habits. For example, the frequently used navigation icon is placed in the center of the main screen, and the music control bar is fixed in a commonly used position.

[0082] In one possible implementation, upon detecting the digital key device corresponding to the digital key, the vehicle's digital key master module can notify the multimedia host to enter a standby state, allowing the screen to quickly light up when the user enters the vehicle, facilitating user interaction. Alternatively, after the digital key device enters the vehicle's corresponding driving intention recognition area, the corresponding user's identity account information can be pre-synchronized with the multimedia host. This allows the multimedia host to quickly and automatically log the user account into the multimedia system upon entry, facilitating user operations under their own account.

[0083] In an embodiment of the present application, a digital key connection method is provided. When a vehicle is in single-connection mode, if a user approaches the vehicle holding a digital key, the vehicle can directly establish a connection with the digital key device and accurately determine the user's boarding and driving intentions by locating the digital key device. After determining the user's driving intention, the vehicle can also automatically receive a vehicle unlock signal triggered by the digital key device, achieving seamless unlocking and logging the user account associated with the digital key into the multimedia system, thereby enhancing the user's driving experience.

[0084] See also Figure 5 , Figure 5 A flowchart of a digital key login method in a digital key connection method provided in an embodiment of the present application.

[0085] like Figure 5 As shown, when the vehicle is in multi-connection mode, the digital key login method in the digital key connection method may at least include:

[0086] S502: When multiple digital key devices corresponding to digital keys are detected, a communication link is established with each digital key device, and each digital key device is continuously located.

[0087] Optionally, see Figure 4 In multi-connection mode, if the vehicle detects multiple digital key devices corresponding to digital keys within the digital key broadcast range, it can establish a communication link with each digital key device and continuously locate each digital key device. In addition to allowing multi-channel connection, the digital key broadcast in multi-connection mode can adopt the same communication method as the single connection mode, such as low-power Bluetooth communication alone, ultra-wideband communication, or a collaborative communication method of low-power Bluetooth and ultra-wideband. The specific connection process between the vehicle and the digital key device is not repeated here.

[0088] S504: When at least one digital key device enters a driving intention recognition area corresponding to the vehicle, unlocking is performed in response to a vehicle unlocking signal sent by at least one digital key device via a communication link.

[0089] Optionally, see Figure 4 When at least one digital key device enters the vehicle's corresponding driving intention recognition area, it indicates that at least one digital key holder currently intends to drive the vehicle. In this case, further verification of the driver's identity is necessary to accurately log into the multimedia system and enhance the user's driving experience.

[0090] Alternatively, the digital key device can actively unlock the vehicle by sending a vehicle unlock signal via the communication link, or the vehicle can unlock the vehicle by identifying the status of the door handle. After the vehicle is unlocked, the user often gets in. Since the user is closer to the location where the key is connected to the broadcast device in the vehicle, a better signal can be used to obtain a more accurate location inside the vehicle than outside the vehicle. In this case, even if multiple users with digital keys have entered the vehicle, their specific locations inside the vehicle will be different. Therefore, the user's precise location inside the vehicle can be further used to determine that the user in the main driver's seat is the current driver.

[0091] S506: Determine the target device and target digital key corresponding to the driver, and log in to the multimedia system in the vehicle according to the user identity information corresponding to the target digital key.

[0092] Optionally, when determining the target device and target digital key corresponding to the driver, if only one digital key device has entered the driving intention recognition area corresponding to the vehicle, then the digital key device in the driving intention recognition area can be directly determined as the target device corresponding to the driver and the target digital key corresponding to the target device can be determined. However, if multiple digital key devices enter the driving intention recognition area corresponding to the vehicle, it is necessary to further obtain the precise positioning of the users of the digital key devices in each vehicle, and then determine the digital key device in the main driving area as the target device corresponding to the driver based on the precise positioning in each vehicle, and determine the target digital key corresponding to the target device. After determining the identity of the driver, the vehicle can start the automatic account login process based on the user identity information corresponding to the target digital key, and send the user identity information corresponding to the digital key to the multimedia host, so that the multimedia host uses the user identity information to log in to the multimedia system.

[0093] In an embodiment of the present application, a digital key connection method is provided. In a multi-connection mode, when a digital key approaches the vehicle, the vehicle can establish a connection with all identifiable digital key devices and accurately determine the intention of each user to get on the vehicle and the driving intention by locating the position of the digital key device. After the vehicle is unlocked without feeling, the device and digital key corresponding to the driver can be further determined, so that the user account corresponding to the driver can be logged into the multimedia system, thereby improving the accuracy of the main driver identification. When determining the driver's identity, if only one digital key device enters the driving intention identification area, it can be directly confirmed as the driver; but if multiple digital key devices are identified to enter the driving intention identification area, the identity of the main driver can be further determined based on the more precise positioning of the digital key device in the car after the user gets on the vehicle, thereby achieving accurate login of the driver's account on the multimedia system.

[0094] In traditional digital key implementations, key connection broadcasts typically use a fixed frequency and are not specific to specific use cases. However, different scenarios require different broadcasts, and using only fixed frequencies and parameters to control broadcasts wastes power. Therefore, the present invention provides a method for controlling key connection broadcasts in a vehicle, in addition to a digital key connection method.

[0095] Optionally, when at least one digital key device corresponding to a digital key is detected, the broadcast period of the key connection broadcast can be adjusted according to the distance between each digital key device and the vehicle. The broadcast period is positively correlated with the distance. In this way, the vehicle can gradually shorten the broadcast period as the digital key device gets closer, saving unnecessary energy while ensuring the efficiency of digital key connection when the user is close to the vehicle. For example, when no user holding a digital key device enters the connection range of the vehicle, the vehicle only needs to broadcast at a lower scanning period, such as 300ms; when the digital key device is detected entering the connectable area of the vehicle, the broadcast interval is shortened to 200ms as the broadcast period; when the digital key device is close to the vehicle body, the broadcast period is further shortened to within 200ms, such as 100ms, 50ms, etc.

[0096] Similarly, the embodiments of the present application take into account that in single-connection mode, only one digital key device needs to be connected, while in multi-connection mode, multiple digital key devices may need to be connected simultaneously. Therefore, the vehicle can also adaptively select the broadcast cycle according to the different connection modes, which can also achieve the effect of reducing energy consumption and improving key connection performance. Specifically, when determining the broadcast cycle of the key connection broadcast based on the current digital key connection mode, the first broadcast cycle corresponding to the single-connection mode is longer than the second broadcast cycle corresponding to the multi-connection mode. This makes it faster to locate and connect each key in the scenario where multiple keys are connected at the same time, and the user experience will be better.

[0097] The two broadcast control strategies described above can be implemented separately or in combination. For example, when no user holding a digital key device enters the vehicle's connection range, the vehicle broadcasts with a lower scanning cycle of 300ms, regardless of whether it is in multi-connection mode or single-connection mode. When a digital key device is detected entering the vehicle's connectable area, the broadcast cycle is shortened to 200ms for both multi-connection mode and single-connection mode. When the digital key device is close to the vehicle body, a 100ms broadcast cycle is used in single-connection mode, while a shorter 50ms broadcast cycle is used in multi-connection mode. This reduces the vehicle's standby power consumption in single-connection mode, and ensures that multiple authorized mobile terminals can simultaneously discover and request to connect to the vehicle in multi-connection mode.

[0098] Furthermore, if there is almost no need for digital key connection while the vehicle is driving, then when the vehicle power is in the on state and the vehicle speed reaches a preset threshold, the key connection broadcast can be turned off to reduce unnecessary power consumption and increase the vehicle's range; correspondingly, when the vehicle is in the off state or when the door status changes after the vehicle is started, it means that the vehicle may need to handle the digital key connection demand at any time. In this case, the key connection broadcast can be started to prepare for the digital key connection at any time. Through the above key connection broadcast control method, the embodiment of the present application reasonably divides the key connection broadcast on and off timing and cycle according to the vehicle status, digital key position, etc., to achieve an optimal power consumption solution for multiple scenarios.
