Technical Field

[0001] This application relates to the field of communications, and more particularly to a device interconnection method, apparatus, and system. Background Technology

[0002] Currently, vehicles, as independent means of transportation, are typically isolated from each other during daily driving and parking. This lack of interaction between vehicles results in low interaction efficiency and negatively impacts the user experience. Summary of the Invention

[0003] This application provides a device interconnection method, apparatus, and system that enables communication between the current vehicle and other vehicles based on the existing digital key system in the vehicle, reducing the human and hardware costs of communication between vehicles and making it easy to implement.

[0075] To facilitate understanding of the embodiments of this application, the following points will be explained first:

[0076] First, in the embodiments of this application, the indication includes explicit indication (also known as direct indication) and implicit indication (also known as indirect indication). Explicit indication information A refers to including information A; implicit indication information A refers to indicating information A through the correspondence between information A and information B and direct indication information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured; or it can refer to indicating information A through information B and preset rules.

[0077] Second, in the embodiments of this application, information C is used to determine information D, which includes determining information D based solely on information C, as well as determining it based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, in the case where information D is determined based on information E, and information E is determined based on information C.

[0078] Third, in the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the preceding and following related objects, but it does not exclude the possibility of indicating an "and" relationship. The specific meaning can be understood in conjunction with the context. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Here, a, b, and c can be single or multiple.

[0079] Fourth, in the embodiments of this application, the use of prefixes such as "first" and "second" is merely for the purpose of distinguishing and describing different things belonging to the same name category, and does not constrain the order, size, or quantity of things. For example, "first threshold" and "second threshold" are simply different thresholds, and there is no temporal order, size, or priority relationship between them.

[0080] Fifth, the "sending" and "receiving" in the embodiments of this application can be performed between devices, such as between a second device and a first device; or they can be performed within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0081] Sixth, in the embodiments of this application, "when," "if," and "if" all refer to the device making corresponding processing under certain objective circumstances, and are not limited to a time, nor do they require the device to make a judgment action when it is implemented, nor do they mean that there are other limitations.

[0082] Seventh, in the embodiments of this application, the words "example," "exemplarily," "for example," or "such as" are used to indicate that they are examples, illustrations, or explanations. Any embodiment or design that is described as "example," "exemplarily," "for example," or "such as" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a specific manner.

[0083] Eighth, the device interconnection method in the embodiments of this application is applied to a vehicle or other devices in a vehicle. These other devices may be, for example, hardware units, software modules, or a combination of hardware units and software modules. These other devices include, but are not limited to, vehicle-mounted terminals, vehicle-mounted controllers, vehicle-mounted modules, vehicle-mounted components, vehicle-mounted chips, vehicle-mounted units, vehicle-mounted radar, or vehicle-mounted cameras, and other sensors. The vehicle can implement the device interconnection method provided in the embodiments of this application through these other devices.

[0084] Of course, the device interconnection method in this application embodiment can also be used in other smart terminals besides vehicles, or installed in other smart terminals besides vehicles, or installed in components of such smart terminals. The smart terminal can be intelligent transportation equipment, robots, etc. For example, it includes, but is not limited to, the smart terminal itself or its controller, chip, radar, camera, and other sensors, as well as other components.

[0085] The embodiments of this application can be applied to intelligent driving devices, or to devices within intelligent driving devices. To facilitate understanding of the solutions in this application, the following will first combine... Figure 1 and Figure 2 A detailed description of intelligent driving equipment is provided.

[0086] Figure 1 This is a functional block diagram of an intelligent driving device 100 to which this application embodiment applies. For example... Figure 1 As shown, the intelligent driving device 100 may include a perception system 120, a computing platform 150, and a communication device 140.

[0087] The perception system 120 may include several sensors for sensing information about the environment surrounding the intelligent driving device 100. For example, the perception system 120 may include a positioning system, which may be a global navigation satellite system (GNSS), such as GPS or BeiDou. Alternatively, the perception system 120 may also include one or more of the following: an inertial measurement unit (IMU), a vibration sensor, a lidar, millimeter-wave radar, ultrasonic radar, and a camera.

[0088] Optionally, the intelligent driving device 100 also includes a display device 130. The display device 130 within the cockpit of the intelligent driving device 100 is mainly divided into two categories: the first is an in-vehicle display screen; the second is a projection display screen, such as a head-up display (HUD). An in-vehicle display screen is a physical display screen and an important component of the in-vehicle infotainment system. Multiple displays can be installed in the cockpit, such as a digital instrument cluster display screen and a central control screen. In some possible implementations, one or more of the aforementioned in-vehicle displays can be human-machine interfaces (HMIs), for example, the central control screen can be an HMI. A head-up display, also known as a head-up display system, is mainly used to display driving information such as speed and navigation on a display device in front of the driver (e.g., on the windshield). This reduces the driver's eye-shifting time, avoids pupil changes caused by eye-shifting, and improves driving safety and comfort. HUDs include, for example, combiner-HUD (C-HUD) systems, windshield-HUD (W-HUD) systems, and augmented reality HUD (AR-HUD) systems.

[0089] In this embodiment of the application, the basic information of other intelligent driving devices and the first control, etc., can be displayed through the display device 130. For details, please refer to the following text. This embodiment of the application does not follow any specific limitations.

[0090] The intelligent driving device 100 also includes a communication device 140. The communication device 140 can be used to communicate with other devices, such as devices in the cloud. The communication device 140 may include, for example, a vehicle-to-everything (V2X) communication unit, a master node of a digital key, a slave node, etc.

[0091] It should be understood that V2X may include, but is not limited to, one or more of the following communication methods: vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), vehicle-to-network (V2N), or vehicle-to-device (V2D). The network may include cellular networks; the device may include smartphones or other portable devices.

[0092] In this embodiment, the intelligent driving device 100 can communicate with other intelligent driving devices through the master-slave node of the digital key.

[0093] Some or all of the functions of the intelligent driving device 100 can be controlled by the computing platform 150.

[0094] For example, the computing platform 150 may include processors 151 to 15n. In this embodiment, a processor is a circuit with signal processing capabilities. In one implementation, the processor may be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a type of microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships of hardware circuits are fixed or reconfigurable. For example, the processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. In addition, the computing platform 150 may also include memory for storing instructions, and some or all of the processors 151 to 15n can call the instructions in memory to implement the corresponding functions.

[0095] The computing platform 150 can also control the operation of the intelligent driving system, which may include an advanced driving assistant system (ADAS) and an autonomous driving system (ADS). The intelligent driving system uses various sensors on the vehicle (including but not limited to: lidar, millimeter-wave radar, cameras, ultrasonic sensors, GPS, and inertial measurement units) to acquire information from the vehicle's surroundings and analyzes and processes the acquired information.

[0096] In this embodiment, the computing platform 150 can also determine that the interconnection function of the intelligent driving device 100 is enabled, and that the interconnection function of another intelligent driving device is also enabled, and then control the digital key system to establish a communication connection with the digital key system of the other intelligent driving device. This allows the two intelligent driving devices to interact and communicate.

[0097] At different levels of autonomous driving (or intelligent driving levels, ranging from L0 to L5, totaling six levels), intelligent driving systems can achieve different levels of automated driving assistance based on artificial intelligence algorithms and information acquired by multiple sensors. These levels of autonomous driving are based on the classification standards of the Society of Automotive Engineers (SAE). Level L0 is no automation; Level L1 is driver assistance; Level L2 is partial automation; Level L3 is conditional automation; Level L4 is high automation; and Level L5 is full automation. At levels L1 to L3, the task of monitoring road conditions and reacting is jointly completed by the driver and the system, requiring the driver to take over dynamic driving tasks. Levels L4 and L5 allow the driver to completely transform into a passenger. Currently, the functions that intelligent driving systems can achieve mainly include, but are not limited to: adaptive cruise control, automatic emergency braking, automatic parking, blind spot monitoring, forward cross-traffic alert / braking, rear cross-traffic alert / braking, forward collision warning, lane departure warning, lane keeping assist, rear collision warning, traffic sign recognition, traffic jam assist, and highway assist. It should be understood that the above-mentioned functions can have specific modes at different levels of autonomous driving (L0-L5). The higher the level of autonomous driving, the more intelligent the corresponding mode.

[0098] Figure 2 A schematic block diagram of an intelligent driving system 200 provided in an embodiment of this application is shown. Figure 2 As shown, the system 200 includes a sensing module 210, a control module 240, and a communication module 250. Optionally, the system 200 may also include a human-computer interaction module 220 and / or a display module 230.

[0099] The sensing module 210 may include Figure 1 The perception system 120 shown includes one or more camera devices and / or one or more radar sensors for collecting environmental information about the area where the vehicle is located, such as the vehicle's location. See details for further information. Figure 1 Description of the location.

[0100] The human-computer interaction module 220 may include Figure 1One or more of the display devices 130 shown may include, for example, an HMI; the human-computer interaction module 220 may also include a sound-generating device (such as a speaker, audio jack, etc.) and a sound-receiving device (such as a microphone). The display module 230 may include... Figure 1 One or more of the display devices 130 shown are included, with display module 230 capable of displaying the vehicle's infotainment interface. Human-machine interaction module 220 can output information such as initial prompts to the user (including voice messages, messages displayed on the screen, etc.).

[0101] Communication module 250 and Figure 1 The communication device 140 is similar, and can be referred to the description above, so it will not be repeated here.

[0102] In this embodiment, the control module 240 can determine whether the interconnection function of other intelligent driving devices is enabled based on the first message from the communication device 140; when the interconnection function of this device and other intelligent driving devices is enabled, the control module 240 can establish a communication connection with other intelligent driving devices through the master and slave nodes of the digital key system in the communication module 250.

[0103] Alternatively, the control module 240 can also obtain user input commands from the human-machine interaction module 220, and then realize the interaction between intelligent driving devices based on the user input commands.

[0104] It should be understood that Figure 1 The intelligent driving device 100 shown is Figure 2 The intelligent driving system 200 shown is merely an example. In real-world applications, intelligent driving devices may include more or fewer components, and intelligent driving systems may include more or fewer modules. This application does not impose specific limitations in this regard.

[0105] Currently, vehicles (such as intelligent driving devices) are typically isolated entities, whether in motion or parked. This lack of interaction between vehicles results in low interaction efficiency and negatively impacts the user experience.

[0106] In some scenarios, there is a communication requirement between vehicles.

[0107] For example, both vehicles 1 and 2 are in motion and their destination is a tourist attraction. Users in vehicle 1 and vehicle 2 may need to exchange information about travel routes and / or precautions. However, there is no communication mechanism between vehicle 1 and vehicle 2, preventing users from interacting and fulfilling their growing needs for social interconnection and contextualized interaction.

[0108] In some examples, dedicated short range communication (DSRC) technology can be used to achieve vehicle-to-vehicle communication or vehicle-to-road communication. DSRC is a wireless communication technology based on the IEEE 802.11p standard.

[0109] However, this method is currently commonly used in electronic toll collection (ETC) scenarios and lacks practical applications between vehicles. Furthermore, it requires vehicles to install dedicated chips to handle IEEE 802.11p protocols and intelligent transportation system-related services; it also requires dedicated channels, i.e., independent dedicated radio frequency bands (such as the 5.9GHz band), making vehicle-to-vehicle communication costly and difficult to implement.

[0110] To address the aforementioned technical problems, this application provides a device interconnection method. Vehicles (such as referred to as a first device and a second device) can establish a communication connection via a digital key system. Specifically, when the interconnection function between the first device and the second device is enabled, the first device and the second device can establish a communication connection through the digital key system, enabling interaction between the first device and the second device.

[0111] In this embodiment, communication between the current vehicle and other vehicles is achieved based on the existing digital key system in the vehicle, without the need to add new chips, resulting in minimal software development. This reduces the labor and hardware costs associated with communication between vehicles and is easy to implement.

[0112] In some examples, such as Figure 3 The diagram shown is a schematic of a device interconnection system 300 corresponding to an embodiment of this application. The system 300 may include a first device 301 and a second device 302.

[0113] The first device 301 includes a digital key system 3011. Optionally, the first device 301 may also include a human-computer interaction module 3012. The second device 302 includes a digital key system 3021. Optionally, the first device 302 may also include a human-computer interaction module 3022.

[0114] The digital key system 3011 and the digital key system 3021 can establish a communication connection and communicate with each other.

[0115] For example, digital key system 3021 may send a first message to digital key system 3011; correspondingly, digital key system 3011 may receive the first message from digital key system 3021. Alternatively, digital key system 3011 may send a second message to digital key system 3021; ​​correspondingly, digital key system 3021 may receive the second message from digital key system 3011. The specifics of the first and second messages are described below and will not be detailed here.

[0116] In addition, for either the first or second device, the digital key system in the device can also communicate with the human-machine interface module (e.g., CDC).

[0117] For example, the digital key system 3011 can send a first instruction to the human-computer interaction module 3012 to instruct the human-computer interaction module 3012 to display a specific interface, and the human-computer interaction module 3012 can then display the interface via a display device. Alternatively, based on user input, the human-computer interaction module 3012 can obtain the instruction corresponding to the user input, and the human-computer interaction module 3012 can transmit the instruction to the digital key system 3011, in which case the digital key system 3011 can receive instructions from the human-computer interaction module 3012, etc.

[0118] Similarly, the digital key system 3021 and the human-computer interaction module 3022 can also communicate, as detailed above, and will not be elaborated here.

[0119] Based on the communication between the digital key system and the human-computer interaction module in each device, communication between the human-computer interaction modules of the first device and the second device can be realized.

[0120] For example, based on user input, the human-computer interaction module 3012 can obtain the input message corresponding to the user input and send the input message to the digital key system 3011.

[0121] Digital key system 3011 can send the input message to digital key system 3021; ​​correspondingly, digital key system 3021 can receive the input message from digital key system 3011. Furthermore, digital key system 3021 can send the input message to human-computer interaction module 3022, so that human-computer interaction module 3022 can display a specific interface through a display device based on the input message.

[0122] It is understood that the above process is described using input messages as an example. In actual application scenarios, instructions can be replaced with commands or information, etc. Furthermore, during the input message transmission process, the digital key system 3011 and digital key system 3021 can either transparently transmit the input message or process the input message before forwarding the processed input message to the human-computer interaction module 3022. This application embodiment does not impose specific limitations on this.

[0123] It is understandable that the interconnection between the first and second devices is achieved through a digital key system. The following will combine... Figure 4 Taking a vehicle (the first device is vehicle 1, and the second device is vehicle 2) as an example, the digital key system in the vehicle will be described in detail.

[0124] Figure 4 This is a schematic diagram showing the distribution of master and slave nodes in the digital key system for vehicle 1 and vehicle 2 provided in this application embodiment.

[0125] like Figure 4 As shown, a vehicle's digital key system includes a master node and one or more slave nodes. For example... Figure 4 In this context, the digital key system of vehicle 1 may include master node 1, slave node 2, slave node 3, slave node 4 and slave node 5.

[0126] Among them, the main node 1 can be located in the center area of ​​the vehicle; the secondary nodes 2-5 are located in the left front area, left rear area, right front area and right rear area of ​​the vehicle, respectively.

[0127] Correspondingly, the digital key system of vehicle 2 may also include master node 1, slave node 2, slave node 3, slave node 4, and slave node 5. The master node 1 is located in the central area of ​​the vehicle; slave nodes 2-5 are located in the front left, rear left, front right, and rear right areas of the vehicle, respectively.

[0128] Alternatively, it can be understood that in vehicle 1 or vehicle 2, slave nodes 2-5 are distributed around master node 1, so that all slave nodes 2-5 can communicate with master node 1. Or, in practical application scenarios, the master node and slave nodes can also be set in other locations in the vehicle, and this application embodiment does not specifically limit this.

[0129] The slave nodes of vehicle 1 and vehicle 2 can communicate with each other.

[0130] For example, any slave node (referred to as slave node a) among slave nodes 2-5 of vehicle 2, under the instruction of master node 1 in vehicle 2, can send a message to any slave node (referred to as slave node b) among slave nodes 2-5 of vehicle 1; slave node b can receive messages from slave node a, such as unicast messages and / or broadcast messages, and transmit the message to master node 1 in vehicle 1.

[0131] Similarly, slave node b can be used to receive messages from master node 1 in vehicle 1 and send the messages to slave node a in vehicle 2; slave node a can receive messages from slave node b and send the messages to master node 1 in vehicle 2.

[0132] For example, the master node 1 of vehicle 1 can receive a message from slave node a in vehicle 2 through slave node b, and establish a communication connection with vehicle 2 based on the message; or generate a control command based on the message, and instruct other devices in vehicle 1 to execute the control command through the control command.

[0133] Alternatively, the master node in a digital key system can be understood as the controller or processing unit of the digital key system. The master node has data processing capabilities and can communicate with slave nodes.

[0134] above Figure 4 The example shown uses nodes 2-5 located in the front left, rear left, front right, rear right, left center, and right center areas of the vehicle, respectively. However, the embodiments of this application are not limited to this. For example, nodes 2-5 could also be located in the front left, rear left, front right, rear right, left center, and right center areas of the top of the vehicle, respectively.

[0135] It is understood that, in the embodiments of this application, the communication between the digital key system of the first device and the digital key system of the second device can be implemented based on short-range wireless communication technology. Short-range wireless communication technology may include, but is not limited to, near field communication (NFC), Bluetooth Low Energy (BLE), ultra-wideband (UWB), Sparklink Low Energy (SLE), or Sparklink Basic (SLP), etc. Alternatively, with the development of the communication / terminal field, other wireless communication technologies may also be used for communication. The embodiments of this application do not impose specific limitations on this.

[0136] Below, in conjunction with Figures 5 to 8This application provides a detailed description of the device interconnection method according to embodiments of the present application. The following embodiments can be combined with each other, and similar concepts or processes may not be repeated in some embodiments. The specific forms and quantities of the devices shown are merely examples and should not constitute any limitation on the implementation of the method provided in this application. Below, the device interconnection method according to embodiments of the present application will be described in detail using the digital key system of the first device (vehicle 1) as an example.

[0137] Figure 5 This is a schematic flowchart of a device interconnection method 500 provided in an embodiment of this application. Figure 5 As shown, method 500 includes the following steps:

[0138] S501, The digital key system of the first device receives the first message.

[0139] The first message comes from the digital key system of the second device.

[0140] The first message can be a broadcast message. That is, the digital key system of the second device broadcasts the first message, and the digital key system of the first device detects the broadcast first message and retrieves it.

[0141] The first message may include basic information about the second device.

[0142] Optionally, the basic information of the second device includes one or more of the following: device name, model information, color information, or license plate number information. The license plate number information can be all or part of the license plate number; this embodiment does not impose specific limitations on this.

[0143] For example, the basic information of the second device could be: Vehicle A - White - 330. Alternatively, the basic information of another second device could be: Vehicle B - Black - 231.

[0144] It should be understood that the above description of the basic information of the second device is only an example. The basic information of the second device may also include other information, such as the year of manufacture of the second device. This application embodiment does not impose specific limitations on this.

[0145] S502, when the interconnection function of the first device is enabled and the first message indicates that the interconnection function of the second device is enabled, the first device establishes a communication connection with the digital key system of the second device.

[0146] The interconnection function can be used to indicate the interconnection function corresponding to the digital key system. When the interconnection function of the first device is enabled, the first device can establish a connection with the digital key systems of other devices based on the digital key system, thereby realizing the interconnection between the first device and other devices.

[0147] Optionally, the first message can also be used to indicate whether the interconnection function of the second device is enabled. Alternatively, the second device may also send information to the first device to indicate whether the interconnection function of the second device is enabled; correspondingly, the first device obtains this information from the second device and determines whether the interconnection function of the second device is enabled based on the information.

[0148] In some examples, the first message may include an interconnect function flag, which can be used to indicate whether the interconnect function of the second device is enabled or disabled.

[0149] For example, when the interconnect function flag is 1, it indicates that the interconnect function of the second device is enabled; when the interconnect function flag is 0, it indicates that the interconnect function of the second device is disabled.

[0150] It should be understood that the above description of "interconnection function" can also be other, such as "vehicle-to-vehicle interconnection". The interconnection function flag bit can be called the vehicle-to-vehicle interconnection flag bit. This application embodiment does not make specific limitations on this.

[0151] The interconnection function of the first device is enabled, meaning that the first device can broadcast a second message to other devices, indicating that the first device can interconnect. The interconnection function of the second device is enabled, meaning that the second device can broadcast a first message to other devices, indicating that the second device can interconnect.

[0152] When the interconnection function of the first device is enabled, and the first message indicates that the interconnection function of the second device is enabled, it means that the first device can interconnect with the second device, and the first device can establish a communication connection with the second device through the digital key system.

[0153] Thus, communication between the current vehicle and other vehicles can be achieved based on the existing digital key system in the vehicle, without the need to add new chips, resulting in minimal software development. This reduces the labor and hardware costs of communication between vehicles and is easy to implement.

[0154] In some examples, the field names in the first message may include one or more of the following: data type, data length, discovery access resource configuration information data content, data type, data length, and higher-layer broadcast data content. Subfields of the data type field may include discovery access resource configuration information and / or higher-layer broadcast data. The data length may correspond to the discovery access resource configuration information data length and the higher-layer broadcast data length, respectively.

[0155] The access resource configuration information data includes one or more of the following: request offset, maximum request length, request-response offset, global title (GT) negotiation indication, number of requests, number of responses, request type flag, request carried information indication, peer media access layer identifier type, and identifier indication.

[0156] The high-level broadcast data content includes one or more of the following: discovery level, access layer capabilities, device fully local name, universally unique identifier (UUID) for digital vehicle keys, and vendor-defined information. All high-level broadcast data content can be in tag-length-value (TLV) format.

[0157] Optionally, the manufacturer-defined information may include the interconnection function flag of the second device and basic information about the second device.

[0158] It should be understood that the content of the first message described above is only an example, and the first message may include more or less content. This application embodiment does not impose specific limitations on this.

[0159] For example, taking the communication method between the first device and the second device as StarFlash, the first message can be as shown in Table 1 below:

[0160] Table 1: Contents of the First Message

[0161]

[0162] The first message in Table 1 above includes the field names of multiple fields and the names of subfields (or field descriptions).

[0163] Specifically, the field names are, in order: Data Type, Data Length, Discovery Access Resource Configuration Information Data Content, Data Type, Data Length, and Higher-Level Broadcast Data Content. The Data Type field can include subfields for Discovery Access Resource Configuration Information and Higher-Level Broadcast Data. The Data Length corresponds to the data length of both Discovery Access Resource Configuration Information and Higher-Level Broadcast Data.

[0164] The access resource configuration information data includes the request offset, the maximum length of the request, the offset of the request and response, the GT negotiation indication, the number of requests, the number of responses, the request type flag, the request carried information indication, the peer media access layer identifier type, and the identifier indication.

[0165] The high-level broadcast data includes discovery level, StarFlash access layer capabilities, device full local name, StarFlash digital car key UUID, and manufacturer-defined information. All of this high-level broadcast data can be in TLV format.

[0166] Optionally, the manufacturer-defined information may include the interconnection function flag of the second device, basic information of the second device, etc.

[0167] It should be understood that the content of the first message described above is only an example, and the first message may include more or less content. This application embodiment does not impose specific limitations on this.

[0168] Table 1 above describes the content of the first message. Optionally, the second message can also refer to the content of Table 1 above. The vendor-defined information in the second message may include the interconnection function flag of the first device and basic information about the first device, which will not be elaborated further here.

[0169] In some examples, the interconnection function of the first device (or the second device) can be enabled or disabled based on user input. User input can be touch input based on HMI, voice input, or input based on devices such as buttons and knobs. This application does not specifically limit the type of user input.

[0170] Taking HMI-based touch input as an example, users can enable or disable the interconnection function of the first device (or the second device) through controls in the HMI display interface. For instance, based on the user's input operation, the vehicle system can obtain corresponding instructions to control the enabling or disabling of the interconnection function of the first device (or the second device).

[0171] The vehicle-mounted system can be understood as the vehicle's cockpit domain controller (CDC), but this application does not specifically limit this.

[0172] For example, such as Figure 6 The image shown is a schematic diagram of the display interface of a vehicle provided in an embodiment of this application.

[0173] like Figure 6 As shown, interface 60 includes a "Visible to Strangers" control and a corresponding checkbox. When the checkbox corresponding to the "Visible to Strangers" control is not checked, the vehicle system responds to the user's input operation on the checkbox, such as a click, to enable the vehicle's connectivity function; when the checkbox corresponding to the "Visible to Strangers" control is checked, the vehicle system responds to the user's input operation on the checkbox to disable the vehicle's connectivity function.

[0174] Optionally, after the vehicle's connectivity function is activated, it needs to display its basic information to other vehicles, which may include some privacy information. Therefore, interface 60 may also include a "Privacy Policy" control and a corresponding checkbox. Users can check the "Visible to Strangers" control when selecting the "Visible to Strangers" control, allowing the vehicle to display its basic information to other vehicles.

[0175] It should be understood that both the first and second devices can enable or disable the interconnection function in the above manner. For the sake of simplicity, they will not be described in detail here.

[0176] In some scenarios, when the interconnection function of the devices is enabled, both devices (the first device and the second device) can broadcast messages. The device that receives the broadcast message first can send a communication connection request to the sender of the broadcast message, so that the digital key system of the first device and the digital key system of the second device can establish a communication connection.

[0177] This application describes an embodiment that includes a digital key system 1 in the first device and a digital key system 2 in the second device.

[0178] With the interconnection function of the second device enabled, digital key system 2 can broadcast a first message. Correspondingly, digital key system 1 receives the first message from digital key system 2.

[0179] With the interconnection function of the first device enabled, digital key system 1 can broadcast a second message. Correspondingly, digital key system 2 receives the second message from digital key system 1.

[0180] In some scenarios, if the digital key system 1 receives the first message earlier than the digital key system 2 receives the second message, the digital key system 1 can send a communication connection request to the digital key system 2 first, thereby establishing a communication connection with the digital key system 2.

[0181] Alternatively, if the digital key system 2 receives the second message earlier than the digital key system 1 receives the first message, the digital key system 2 may send a communication connection request to the digital key system 1 first, thereby establishing a communication connection with the digital key system 1. This application embodiment does not impose specific limitations in this regard.

[0182] In some examples, embodiments of this application are described using the example of digital key system 1 sending a communication connection request to digital key system 2 first, thereby establishing a communication connection with digital key system 2.

[0183] like Figure 7The diagram shown is a flowchart illustrating a device interconnection method 700 provided in an embodiment of this application. The first device may include a digital key system 1 and a human-machine interaction module 1; the second device may include a digital key system 2 and a human-machine interaction module 2. As shown... Figure 7 As shown, method 700 includes the following steps:

[0184] S701, Digital Key System 2 sends a first message to Digital Key System 1. Correspondingly, Digital Key System 1 receives the first message from Digital Key System 2.

[0185] Optionally, with the interconnection function of the second device enabled, the digital key system 2 can broadcast the first message.

[0186] When the distance between the first device and the second device is less than the communication distance of the digital key system, the digital key system 1 can detect the first message.

[0187] The first message may include basic information about the second device, such as its model, color, or license plate number.

[0188] Optionally, the first message can also be used to indicate whether the interconnection function of the second device is enabled.

[0189] In some examples, where the second device includes multiple devices, the digital key system 1 can also receive first messages from multiple digital key systems 2, and subsequently, the digital key system 1 can establish communication connections with multiple digital key systems 2.

[0190] Optionally, with the interconnection function of the first device enabled, digital key system 1 can broadcast a second message. Method 700 may further include S7011: digital key system 1 sends a second message to digital key system 2. Correspondingly, digital key system 2 receives the second message from digital key system 1.

[0191] For details on S7011, please refer to the above-mentioned S701, which will not be repeated here.

[0192] In this way, digital key system 1 can obtain the first message from the second device, and digital key system 2 can also obtain the second message from the first device.

[0193] S702, when the interconnection function of the first device is enabled and the first message indicates that the interconnection function of the second device is enabled, the digital key system 1 sends a communication connection request to the digital key system 2.

[0194] For details, please refer to S502, which will not be elaborated here.

[0195] S703, Digital Key System 2 establishes a communication connection with Digital Key System 1 based on the communication connection request.

[0196] Optionally, after digital key system 2 establishes a communication connection with digital key system 1, signals (or information, etc.) can be transmitted between digital key system 2 and digital key system 1.

[0197] Optionally, the communication connection can be an NFC, BLE, UWB, SLE, or SLP connection, and this application embodiment does not impose specific limitations on this.

[0198] Optionally, if there are multiple digital key systems 2, digital key system 1 can establish communication connections with multiple digital key systems 2.

[0199] S704, the digital key system 1 sends a first instruction to the human-machine interaction module 1 based on the first message. Correspondingly, the human-machine interaction module 1 receives the first instruction from the digital key system 1.

[0200] After digital key system 1 and digital key system 2 establish a communication connection, that is, after the first device and the second device establish a communication connection, the digital key system can send a first instruction to the human-machine interaction module 1 of the first device based on a first message. The first instruction is used to instruct the display device of the human-machine interaction module 1 to display the basic information of the second device and the first control.

[0201] The first control may include interactive controls between the first device and the second device. For example, the first control may include one or more of the following: greeting, leaving a message, making a call, video, or multimedia. The multimedia control may include online game controls, shared movie-watching controls, etc., and this application embodiment does not impose specific limitations on this.

[0202] S705, the human-computer interaction module 1 displays the basic information of the second device and the first control through the display module in the human-computer interaction module 1 based on the first instruction.

[0203] Optionally, the human-computer interaction module 1 can display the basic information of the second device and the first control on the vehicle's large screen through the display module, or it can also display it on other screens in the vehicle, such as the rear entertainment screen. This application embodiment does not impose specific limitations on this.

[0204] Optionally, when the first device obtains basic information about multiple second devices, the first device may display the basic information about the multiple second devices and the corresponding first control using a display module.

[0205] For example, such as Figure 8 The diagram shown is a schematic of a display interface 80 provided in an embodiment of this application.

[0206] Interface 80 includes basic information about multiple second devices and their corresponding first controls. For example, it includes vehicle A - white - 330 and its corresponding first control; vehicle B - black - 231 and its corresponding first control; vehicle C - red - 688 and its corresponding first control; and vehicle D - blue - 510 and its corresponding first control.

[0207] It should be understood that the above description of interface 80 is only an example, and interface 80 may also include more or less basic information of the second device and the first control. This application embodiment does not impose specific limitations on this.

[0208] S704 and S705 above describe the process by which the human-machine interface module 1 displays basic information of the second device and the first control after the digital key system 2 establishes a communication connection with the digital key system 1. In some examples, after the digital key system 2 establishes a communication connection with the digital key system 1, the human-machine interface module 2 can also display basic information of the first device and the first control. Method 700 may also include S7041 and S7051:

[0209] S7041. After establishing a communication connection with Digital Key System 1, Digital Key System 2 sends a third instruction to Human-Machine Interaction Module 2 based on the second message. Correspondingly, Human-Machine Interaction Module 2 receives the third instruction from Digital Key System 2.

[0210] The third instruction can be used to instruct the display device of the human-computer interaction module 2 to display the basic information of the first device and the first control.

[0211] S7051, the human-computer interaction module 2 can display the basic information of the first device and the first control through the display module based on the third instruction.

[0212] For details, please refer to S704 and S705, which will not be elaborated here.

[0213] S706. Based on the user's input operation, the human-computer interaction module 1 obtains the first input message and sends the first input message to the human-computer interaction module 2 through the digital key system 1 and the digital key system 2. Correspondingly, the human-computer interaction module 2 receives the first input message from the human-computer interaction module 1 through the digital key system 1 and the digital key system 2.

[0214] In some examples, the user's input can be an action on the first control in interface 80, such as clicking, swiping, or double-clicking, and the first input message can be a message based on or generated by that input action. Alternatively, the user's input can be replaced by voice input, and the first input message can be the input message corresponding to the voice input, that is, the message corresponding to the voice uttered by the user.

[0215] This application uses vehicle A-white-330 as an example to illustrate the embodiments of the second device.

[0216] For example, the user's input operation can be a greeting control 801 for vehicle A-white-330 in the touch interface 80, and the first input message can be a greeting message for vehicle A.

[0217] Optionally, the content of the greeting message can be user-defined, that is, content entered by the user in real time.

[0218] For example, after using the greeting control 801 on the touch interface 80, the user can input the content of the greeting message by text or by voice.

[0219] Alternatively, the content of the greeting message can be preset content in the vehicle (preset content by the vehicle communication service provider or the user), which is the system-triggered message after the user clicks the control.

[0220] For example, after a user interacts with the greeting control 801 on the touch interface 80, the human-computer interaction module 1 can send a preset greeting message to the human-computer interaction module 2 based on this operation.

[0221] For example, the preset greeting message can be "Hello!". Alternatively, the preset greeting message can be other than these, and this embodiment does not impose any specific limitations on it.

[0222] Optionally, the preset greeting message may also include greeting messages with multiple contents. After the user touches the greeting control 801 on the touch interface 80, multiple greeting messages with multiple contents can be displayed. The user can select one of the greeting messages as the first input message. This application embodiment does not specifically limit this.

[0223] For example, the preset greeting messages could be: Greeting message 1: "Hello!"; Greeting message 2: "Good morning!". The user can select one of the greeting messages as the first input message.

[0224] For another example, the user's input operation can be a message control 802 on the touch interface 80 for vehicle A-white-330, and the first input message can be a message for vehicle A. For instance, the user can touch the message control 802 and enter a message.

[0225] Alternatively, user input can be voice input for message messages. For example, users can enter a voice message.

[0226] For another example, the user's input operation can be the call control 803 on the touch interface 80 for vehicle A-white-330; or, the user's input operation can be a voice input call request. The first input message can be a call request message for vehicle A.

[0227] For another example, the user's input operation can be the video control 804 of vehicle A-white-330 in the touch interface 80; or, the user's input operation can be a voice input video request. The first input message can be a video request message for vehicle A.

[0228] For another example, the user's input operation can be the multimedia control 805 of vehicle A-white-330 in the touch interface 80; or, the user's input operation can be a voice input multimedia request.

[0229] The first input message can be a multimedia request message for vehicle A.

[0230] Optionally, the multimedia request message may be an online game request message or a shared movie viewing request message, etc., and this application embodiment does not impose specific limitations on this.

[0231] Optionally, the user's input operation can also be a first control corresponding to another second device in the touch interface 80, and this application embodiment does not impose specific limitations on this.

[0232] S707, the human-computer interaction module 2 displays the first input message through the display module.

[0233] Optionally, the human-computer interaction module 2 can display the first input message through the display module.

[0234] For example, if the first input message is a greeting message or a message, the human-computer interaction module 2 can display the content of the greeting message or the message through the display module.

[0235] For another example, if the first input message is a call request message, a video request message, or a multimedia request message, the human-computer interaction module 2 can display the call request message, video request message, or multimedia request message through the display module.

[0236] For example, a call request message may include an consent control and a disagree control. The consent control instructs the user of the second device to consent to the call with the user of the first device. The disagree control instructs the user of the second device to disagree to the call with the user of the first device.

[0237] Correspondingly, video request messages and multimedia request messages may also include consent and disagreement controls.

[0238] When the first input message is a call request message, a video request message, or a multimedia request message, method 700 may further include the following S708:

[0239] S708. Based on the user's input, the human-computer interaction module 2 obtains the second input message and sends it to the digital key system 2. Correspondingly, the digital key system 2 receives the second input message.

[0240] Based on the user's input operation on the second device, the human-computer interaction module 2 can obtain the second input message.

[0241] In some examples, the user's input on the second device can be a touch-sensitive "agree" or "disagree" control on the first input message. Alternatively, the user's input on the second device can be a voice input requesting agreement or disagreement.

[0242] For example, the user's input on the second device could be a touch control indicating disagreement with the call request message, or the user's input could be a voice message indicating disagreement with the call request. The second input message could be disagreement with the call request.

[0243] If the second input message can be a statement of disagreement with the call request, the digital key system 2, upon receiving the second input message, can display it through the human-machine interface module 2 to instruct the user of the second device to disagree with the call request.

[0244] As another example, the user's input on the second device could be a touch-sensitive "agree" control for the call request message, or the user's input could be a voice message indicating agreement to the call request. The second input message could be an agreement to the call request.

[0245] If the second input message can be a request to agree to the call, the digital key system 2 can execute the following S709:

[0246] S709, Digital Key System 2 establishes an interactive connection with Digital Key System 1.

[0247] For example, digital key system 2 can establish a call connection, video connection, or multimedia connection with digital key system 1.

[0248] S710, Digital Key System 1 instructs Human-Machine Interaction Module 1 to display the interactive interface.

[0249] For example, the digital key system 1 can display a call interface, video interface or multimedia interface through the human-computer interaction module 1.

[0250] Optionally, method 700 also includes S7101:

[0251] S7101, the digital key system 2 can display an interactive interface through the human-computer interaction module 2.

[0252] For example, the digital key system 2 can display a call interface, video interface or multimedia interface through the human-computer interaction module 2.

[0253] The above embodiments describe a scenario where a user of the first device actively sends a first input message to the second device. In other examples, a user of the second device may also actively send a third input message to the first device to establish an interactive connection with the first device.

[0254] For example, if digital key system 1 and digital key system 2 establish a call connection, and subsequently, if the user of the second device has video needs, they can input a third input message through human-computer interaction module 2, thereby establishing a video connection between digital key system 2 and digital key system 1.

[0255] Method 700 may also include the following S711-S715:

[0256] S711. Based on the user's input, the human-computer interaction module 2 obtains a third input message and sends the third input message to the human-computer interaction module 1 through the digital key system 2 and the digital key system 1. Correspondingly, the human-computer interaction module 1 receives the third input message from the human-computer interaction module 2 through the digital key system 1 and the digital key system 2.

[0257] Optionally, the user's input operation can be touching a first control corresponding to the first device, and the third input message can be the input message corresponding to the first control. Alternatively, the user's input operation can be a voice input operation, and the third input message can be the input message corresponding to the voice input operation.

[0258] For example, the user's input could be a touch gesture to greet the first device, and the third input message could be a greeting message to the first device. Alternatively, the user's input could be voice input of the greeting message.

[0259] Optionally, this step can be referred to in detail in S706 above, and will not be repeated here.

[0260] S712, the human-computer interaction module 1 displays the third input message through the display module.

[0261] For example, the third input message can be any of the following from the second device: a greeting message, a message, a call request message, a video request message, or a multimedia request message.

[0262] In the case where the third input message is a greeting message or a message, the human-computer interaction module 1 can display the content of the greeting message or the message through the display module.

[0263] For another example, when the third input message is a call request message, a video request message, or a multimedia request message, the human-computer interaction module 1 can display the call request message, video request message, or multimedia request message through the display module.

[0264] For example, a call request message may include an consent control and a disagree control. The consent control instructs the user of the second device to consent to the call with the user of the first device. The disagree control instructs the user of the second device to disagree to the call with the user of the first device.

[0265] Correspondingly, video request messages and multimedia request messages may also include consent and disagreement controls.

[0266] If the first input message is a call request message, a video request message, or a multimedia request message, method 700 may further include S713:

[0267] S713. Based on the user's input, the human-computer interaction module 1 obtains the fourth input message and sends it to the digital key system 2. Correspondingly, the digital key system 2 receives the fourth input message.

[0268] Based on the user's input operation on the first device, the human-computer interaction module 1 can obtain the fourth input message.

[0269] In some examples, the user's input on the first device can be a touch-sensitive "agree" or "disagree" control on a third-party input message. Alternatively, the user's input on the second device can be a voice input request for agreement or disagreement.

[0270] For example, the user's input on the first device can be a touch control indicating disagreement with the call request message, or the user's input can be a voice message indicating disagreement with the call request. The fourth input message can be disagreement with the call request.

[0271] If the fourth input message can be a statement of disagreement with the call request, the digital key system 1, upon receiving the fourth input message, can display it through the human-machine interface module 1 to indicate to the user of the first device that they disagree with the call request.

[0272] As another example, the user's input on the first device could be a touch-sensitive consent control for the call request message, or the user's input could be a voice input message agreeing to the call request. The fourth input message could be an agreement to the call request.

[0273] If the fourth input message can be a request to agree to the call, the digital key system 1 can execute S714:

[0274] S714, Digital Key System 1 establishes an interactive connection with Digital Key System 2.

[0275] For example, digital key system 1 can establish a call connection, video connection, or multimedia connection with digital key system 2.

[0276] For example, in S709, digital key system 1 and digital key system 2 establish a call connection. Subsequently, if the user of the second device has video requirements, a video connection between digital key system 1 and digital key system 2 can be established through S711-S714.

[0277] The S715 and digital key system 2 display an interactive interface through the display module in the human-computer interaction module 2.

[0278] For example, the digital key system 2 can display a call interface, video interface or multimedia interface through the display module in the human-computer interaction module 2.

[0279] Optionally, method 700 also includes S7151:

[0280] S7151, the digital key system 1 displays an interactive interface through the display module in the human-computer interaction module 1.

[0281] For example, the digital key system 1 can display a call interface, video interface or multimedia interface through the display module in the human-computer interaction module 1.

[0282] Optionally, after the digital key system 1 and digital key system 2 establish an interactive connection and the first device interacts with the second device, the first device can also disconnect the interactive connection between digital key system 1 and digital key system 2 based on user input.

[0283] For example, the user input operation of the first device can be to touch the hang-up control on the video call interface to disconnect the video call connection between digital key system 1 and digital key system 2.

[0284] Alternatively, after digital key system 1 and digital key system 2 establish an interactive connection and the first device interacts with the second device, the first device can also disconnect the interactive connection and communication connection between digital key system 1 and digital key system 2 based on user input.

[0285] For example, the user input on the first device could be a touch-screen video call interface to hang up, disconnecting the communication connection between digital key system 1 and digital key system 2. This would disconnect the interactive and communication connections between digital key system 1 and digital key system 2.

[0286] Thus, in this embodiment, communication between the current vehicle and other vehicles is achieved based on the existing digital key system in the vehicle, without the need to add new chips, resulting in minimal software development. This reduces the labor and hardware costs associated with communication between vehicles and is easy to implement.
