[0002] This disclosure claims priority to Chinese patent application No. 2023114327592 filed on October 31, 2023, with applicant Beijing Rockwell Technology Co., Ltd., and application name “Processing method, device, electronic device and vehicle based on Bluetooth key”. The full text of the application is incorporated into this disclosure by reference. Technical Field

[0003] The present disclosure relates to the field of Bluetooth communication technology, and in particular to a processing method, device, equipment, medium, vehicle, and program based on a Bluetooth key. Background Art

[0004] A Bluetooth key (BKey) can control a vehicle via Bluetooth on a mobile phone or other terminal when the vehicle is relatively close to the key. Vehicle control operations such as unlocking or locking doors and opening or closing the trunk can be performed via a Bluetooth key. Therefore, a Bluetooth key can perform the main functions of a physical key and provide more convenient vehicle control operations.

[0005] Currently, Bluetooth keys only support single-connection functionality, meaning a vehicle can only connect to one terminal equipped with a Bluetooth key. To use the Bluetooth key on another terminal, the other terminal must be re-paired and re-connected to the vehicle.

[0055] The term "and / or" herein simply describes an association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can represent the existence of three situations: A alone, A and B simultaneously, and B alone.

For example, "at least one of A, B, and C" can represent any one or more elements selected from the set consisting of A, B, and C.

[0056] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0057] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0058] This embodiment provides a processing method based on a Bluetooth key. The execution subject of the method may be a processing device or apparatus based on a Bluetooth key, which may be configured on the vehicle side, such as on the side of a domain controller (XCU). As shown in FIG1 , the method includes:

[0059] Step 101: Obtain the number of terminals currently connected to the vehicle via the Bluetooth key.

[0060] The terminals that the vehicle is currently connected to with the Bluetooth key can be considered as the vehicle has successfully connected to the Bluetooth key of these terminals. This embodiment can realize multiple connections between the vehicle's Bluetooth key and the vehicle, and can record the number of terminals currently connected to the vehicle via the Bluetooth key in real time.

[0061] It should be noted that the Bluetooth key described in the embodiment of the present disclosure may include: Bluetooth digital key and digital key, etc. The terminal involved in this embodiment, that is, the terminal supporting the Bluetooth key function, may include a smartphone, a smartwatch, and a tablet computer, etc., and this embodiment does not make specific limitations.

[0062] Step 102: If the number of terminals is less than a preset threshold, a first connectable Bluetooth broadcast is sent through the vehicle's Bluetooth main module.

[0063] The preset threshold is greater than or equal to 2.

[0064] Exemplarily, the preset threshold can be used to determine the maximum number of terminal connections for the vehicle for Bluetooth key connection; the specific value of the threshold can be set according to actual needs. For example, if the preset threshold is 3, the maximum number of terminal connections for the vehicle for Bluetooth key connection can be 3; if the preset threshold is 6, the maximum number of terminal connections for the vehicle for Bluetooth key connection can be 6.

[0065] The Bluetooth main module may be a Bluetooth Low Energy (BLE) main module. In this embodiment, if it is determined that the number of terminals currently connected to the vehicle's Bluetooth key is less than a preset threshold, indicating that the Bluetooth main module can still connect to other terminals, the BLE main module may periodically send a first Bluetooth broadcast indicating that it can be connected, so that other terminals can connect to the Bluetooth key based on the first Bluetooth broadcast.

[0066] Exemplarily, the broadcast type of the first Bluetooth broadcast may be a discoverable and connectable type.

[0067] Step 103: Receive, through the Bluetooth main module, a Bluetooth key connection request initiated by the target terminal according to the first Bluetooth broadcast.

[0068] The target terminal may be a terminal that needs to be connected to the Bluetooth key, in addition to the terminal that is currently connected to the Bluetooth key.

[0069] For this embodiment, encryption and decryption authentication can be performed based on the Bluetooth key connection request sent by the target terminal. For example, the BLE main module can send the keychain information carried in the Bluetooth key connection request to the domain controller XCU through the vehicle controller local area network (Controller Area Network, CAN) message. The XCU performs encryption and decryption authentication based on the keychain information, where the XCU sends the CAN message to the BLE main module, and then exchanges information with the target terminal through the BLE main module. If the encryption and decryption authentication is completed, a Bluetooth key connection can be established between the BLE main module and the target terminal.

[0070] Step 104: When it is determined that the Bluetooth master module is successfully connected to the Bluetooth key of the target terminal, the Bluetooth connection information corresponding to the Bluetooth master module is synchronized to each Bluetooth slave module.

[0071] The Bluetooth slave module is used to perform time-sharing connection monitoring scheduling according to the different connection cycles of the terminals connected to each Bluetooth key.

[0072] For example, the Bluetooth connection information may include information such as an access address, a Cyclic Redundancy Check (CRC) initial value, a connection interval, and a frequency hopping channel map.

[0073] The Bluetooth slave module is used to perform time-sharing connection monitoring scheduling according to the different connection cycles of the terminal connected to each Bluetooth key according to the Bluetooth connection information, and then measure the field strength information of the terminal to facilitate positioning of the terminal. The Bluetooth slave module may be a BLE slave module. For example, as shown in Figure 2, it is an example diagram of the architecture involved in the method of this embodiment, wherein CANFD is an upgraded version of the CAN protocol. The XCU can be connected to a BLE master module and multiple BLE slave modules; illustratively, the XCU can also be an integrated computing unit for other domain controls; the XCU can also be connected to a body control module (BCM), an automatic driving drive control unit (FLDCU), an FRDCU, and a tire pressure monitoring system (TPMS) via CANFD.

[0074] If the same connection period is used to schedule connection monitoring for all terminals connected to the Bluetooth key, it will be impossible to determine the field strength information of each terminal, and thus it will be impossible to effectively locate the terminal. Therefore, in this embodiment, different connection periods are used to schedule connection monitoring for these terminals connected to the Bluetooth key, which can achieve effective positioning of terminals connected to multiple Bluetooth keys.

[0075] This embodiment can realize the Bluetooth key supporting multi-connection function, that is, the vehicle can connect to multiple terminals equipped with Bluetooth keys, so that users can use Bluetooth keys to control the vehicle on multiple terminals, reducing the probability of frequent re-pairing, reducing the user's operating burden and time cost, and improving the user experience.

[0076] The multi-connection solution for car Bluetooth keys provided in this embodiment has at least the following advantages:

[0077] Improved convenience: The multi-connection feature allows users to use the same Bluetooth key on multiple phones, reducing the need for frequent re-pairing and improving the user experience. For example, if multiple family members need to use the same car, multi-connection allows family members to use the connected phone directly without having to re-pair the Bluetooth key each time.

[0078] Enhanced security: The multi-connection feature allows users to promptly delete or replace connected phones, reducing the risk of information leakage and vehicle theft. For example, if the Bluetooth key is stolen or lost, users can restrict unauthorized access to the vehicle by deleting the connected phone.

[0079] Increased flexibility: The multi-connection feature allows users to switch between different phones at any time, making it easier for them to use the vehicle in different scenarios. For example, users can connect the key with their work phone at work and their personal phone at home, eliminating the need to frequently switch pairs.

[0080] The usage scenarios of the method of this embodiment may include at least the following:

[0081] Family Sharing: The multi-connection function allows family members to share the same car Bluetooth key, making it convenient for family members to use the vehicle at different time periods.

[0082] Company car: The multi-connection function allows employees in the company to share the same car Bluetooth key, making it convenient for employees to use company vehicles at different time periods.

[0083] Rental Services: Multi-connectivity enables rental service companies to manage vehicle access rights and control vehicle usage during the rental period.

[0084] Furthermore, as a refinement and extension of the above embodiment, in order to illustrate the specific implementation process of the method of this embodiment, a specific method as shown in FIG3 is provided. As shown in FIG3 , the method includes:

[0085] Step 201: Obtain the number of terminals currently connected to the vehicle via the Bluetooth key.

[0086] Step 202: If the number of terminals is less than a preset threshold, a first connectable Bluetooth broadcast is sent through the vehicle's Bluetooth main module.

[0087] The preset threshold is greater than or equal to 2.

[0088] For ease of understanding, this embodiment is mainly described by taking as an example a case where the terminal is a mobile phone, the preset threshold is 3, the Bluetooth master module is a BLE master module, and the Bluetooth slave module is a BLE slave module.

[0089] In this embodiment, the Bluetooth main module's broadcast period can be a certain number of milliseconds (X ms), and the number of milliseconds X can be modified based on actual conditions. Regarding Bluetooth key connections, when the vehicle is connected to three mobile phones, the broadcast type changes to discoverable and non-connectable, and relevant characteristic data is added to the broadcast payload. Based on this characteristic data, the mobile phone can determine that the vehicle has reached the maximum number of connections and cannot make further Bluetooth key connections. In this case, the mobile phone does not initiate the Bluetooth key connection process to reduce resource consumption. When the number of connections is less than three, the broadcast type becomes discoverable and connectable, facilitating Bluetooth key connections for other mobile phones.

[0090] In some embodiments, the first Bluetooth broadcast may include the number of terminals currently connected to the vehicle's Bluetooth key. Furthermore, the first Bluetooth broadcast may also include the number of remaining terminals that can be connected. For example, a byte in the Major Value field of the ibeacon broadcast definition is used to indicate the number of connected phones. This allows the phone to determine whether a Bluetooth key connection is currently available, facilitating the process of initiating a Bluetooth key connection.

[0091] In some embodiments, if the number of terminals currently connected to the vehicle's Bluetooth key reaches the maximum number of connections, the broadcast can still be maintained and the broadcast can be modified to a non-connectable attribute. After scanning, other authorized terminal devices can determine that the number of terminals has reached the maximum number of connections, etc.

[0092] Step 203: Receive, through the Bluetooth main module, a Bluetooth key connection request initiated by the target terminal according to the first Bluetooth broadcast.

[0093] For example, the mobile phone determines that it can initiate the process of Bluetooth key connection based on Bluetooth broadcast, and then sends a corresponding Bluetooth key connection request to request the Bluetooth key connection. The request can carry connection information, such as keychain information used for encryption and decryption authentication. The BLE main module transmits the connection information to the XCU through multi-frame CAN messages, and the XCU then transmits the connection information to the BLE main module through multi-frame CAN messages. Then, the BLE main module interacts with the target terminal through information to achieve encryption and decryption authentication. If the encryption and decryption authentication is completed, a Bluetooth key connection can be established between the BLE main module and the mobile phone. Among them, after any mobile phone Bluetooth key is successfully connected, the connection information data of other mobile phones can be transparently transmitted, and the same multi-frame CAN message can still be used for interaction.

[0094] Step 204: When it is determined that the Bluetooth master module is successfully connected to the Bluetooth key of the target terminal, the Bluetooth connection information corresponding to the Bluetooth master module is synchronized to each Bluetooth slave module through the first communication information corresponding to the target terminal.

[0095] Among them, the first communication information carries the identification of the target terminal, and the different terminals corresponding to each Bluetooth slave module are used to use different communication information to synchronize Bluetooth connection information between each Bluetooth slave module; the Bluetooth slave module can be used to perform time-sharing connection monitoring scheduling according to the different connection cycles of the terminal connected to each Bluetooth key.

[0096] For example, the first communication information may be communication information such as a CAN message, a Local Interconnect Network (LIN) message, etc. The following description mainly takes the case where the first communication information is a CAN message as an example.

[0097] For example, as shown in FIG4 , the synchronization mechanism of Bluetooth connection information may include: after each successful connection, the BLE master module synchronizes the Bluetooth connection information of the BLE slave module through multi-frame CAN messages, so that each BLE slave module performs time-sharing connection monitoring scheduling according to the different connection cycles of the mobile phone connected to each Bluetooth key based on the Bluetooth connection information, and then measures the field strength information of each mobile phone to facilitate the positioning of each mobile phone.

[0098] For example, when connecting to the first mobile phone (Phone1), the BLE master module synchronizes the Bluetooth connection information of the first mobile phone to the BLE slave module through multi-frame CAN message 1 (including Bluetooth connection information such as the Bluetooth monitoring connection data channel access address of the first mobile phone); when connecting to the second mobile phone (Phone2), the BLE master module synchronizes the Bluetooth connection information of the second mobile phone to the BLE slave module through multi-frame CAN message 2 (including Bluetooth connection information such as the Bluetooth monitoring connection data channel access address of the second mobile phone); when connecting to the third mobile phone (Phone3), the BLE master module synchronizes the Bluetooth connection information of the third mobile phone to the BLE slave module through multi-frame CAN message 3 (such as including Bluetooth connection information such as the Bluetooth monitoring connection data channel access address of the third mobile phone).

[0099] In this embodiment, corresponding CAN messages may exist for mobile phones connected to different Bluetooth keys, and the Bluetooth connection information is then synchronized between BLE slave modules through the corresponding CAN messages. For example, the CAN message correspondence is as follows: for the first connected mobile phone, CAN message 1 is used to synchronize the Bluetooth connection information of the BLE slave module, which is used to measure the field strength 1 of the first connected mobile phone through the BLE slave module; for the second connected mobile phone, CAN message 2 is used to synchronize the Bluetooth connection information of the BLE slave module, which is used to measure the field strength 2 of the second connected mobile phone through the BLE slave module; for the third connected mobile phone, CAN message 3 is used to synchronize the Bluetooth connection information of the BLE slave module, which is used to measure the field strength 3 of the third connected mobile phone through the BLE slave module.

[0100] In some embodiments, the CAN message corresponding to the mobile phone may contain the identification of the mobile phone; for example, the identification determination process for the target terminal may include:

[0101] During the authentication process of the Bluetooth key connection of the target terminal, the identification of the target terminal is determined through the fields in the keychain information released by the server.

[0102] In some examples, if the keychain information is consistent with the keychain information corresponding to the terminal connected to the Bluetooth key, the identification of the target terminal is determined based on the fields in the keychain information and the device type of the target terminal.

[0103] For example, a car owner can share a Bluetooth key with other users. After sharing the Bluetooth key, up to three mobile phones can be connected simultaneously when one is already connected. At this time, all three phones have unlocking and vehicle control functions, which can realize the scenario where multiple Bluetooth keys are valid at the same time. After the valid key leaves the vehicle, the valid key inside the vehicle remains unaffected and can continue to use the vehicle. It also satisfies the requirement that multiple mobile phones have simultaneous control of a car, all Bluetooth keys have equal connection permissions, and support three Bluetooth keys being connected at the same time. Moreover, after connecting three mobile phones, the Bluetooth main module can continue to broadcast, but its broadcast changes to discoverable but not connectable, and the fourth mobile phone is not allowed to connect. The special broadcast field is modified to specific content, indicating that the maximum number of connections has been reached.

[0104] There can be a corresponding relationship between the number of devices and accounts. For example, the owner's account is account 1, the first shared user is account 2, the second shared user is account 3, and so on. For example, XCU uses the specific field in the keychain information released by the server to distinguish which account identification (ID) is connected. XCU sends a CAN signal with a specific label to the CAN. All signals with multiple connection numbers need to correspond to the information of the specific field on the server to clearly indicate which mobile phone is connected to the vehicle and performs related vehicle control operations.

[0105] In some application scenarios, since the watch's Bluetooth key is shared from a mobile phone, the watch's keychain is the same as the shared phone. After the watch is connected, the XCU uses the device type in the Bluetooth keychain to distinguish. It should be noted that the multi-connection CAN messages with sequence numbers sent by the BLE end may only be related to the mobile phone connection order, and have nothing to do with the mobile phone ID connection.

[0106] In this embodiment, for the multi-connection transparent transmission BLE controller, the CAN protocol stack needs to support full-duplex function to optimize the multi-link function and ensure that it cannot be interrupted during the sending and receiving processes of multiple frames.

[0107] After receiving the synchronization message, the BLE slave module waits for the communication signal between the BLE master module and the mobile phone to connect and synchronize in the communication channel according to the Channel Map and other information sent by the BLE master module. Once the synchronization is successful, the BLE slave module will perform periodic scheduling monitoring according to the connection cycle of the BLE master module.

[0108] The BLE master module's connection period for Phone 1 is N ms (N is an integer greater than or equal to 1 and represents the connection period interval); the BLE master module's connection period for Phone 2 is (N+x) ms (x can be an odd number greater than or equal to 1); and the BLE master module's connection period for Phone 3 is (Nx, where N is an integer greater than x) ms. These connection periods are fixed values. As shown in Figure 5, assuming x is 5 ms, the BLE master module's connection period for Phone 1 is N ms; the BLE master module's connection period for Phone 2 is (N+5) ms (N is the connection period interval); and the BLE master module's connection period for Phone 3 is (N-5) ms. These connection periods are fixed values, with a 5 ms interval between each of the three phones.

[0109] It should be noted that if one of the three mobile phones is disconnected, the BLE slave module will still perform time-sharing connection monitoring scheduling for the remaining connected mobile phones according to the originally set connection cycle.

[0110] In some embodiments, if it is determined that the Bluetooth main module is successfully connected to the target terminal Bluetooth key, the method of this embodiment may further include:

[0111] The number of terminals currently connected to the Bluetooth key is cumulatively increased by 1; if the number of terminals connected to the vehicle via the Bluetooth key after the cumulative increase of 1 is greater than or equal to the preset threshold, a second Bluetooth broadcast indicating that the connection is not possible is issued through the Bluetooth main module.

[0112] Exemplarily, the second Bluetooth broadcast carries prompt information indicating that the Bluetooth key has reached the maximum number of connections.

[0113] For example, for Bluetooth key connection, when the vehicle is connected to three mobile phones, the broadcast type is changed to a discoverable and non-connectable type, and relevant feature data is added to the broadcast payload content. The mobile phone can determine based on the feature data that the current Bluetooth main module has reached the maximum number of connections and can no longer connect to the Bluetooth key. At this time, the mobile phone may not initiate the Bluetooth key connection process to save resource consumption.

[0114] Step 205: Receive the second communication information sent by each Bluetooth slave module.

[0115] The second communication information carries the identifier of the target terminal and signal measurement information measured according to the connection period corresponding to the target terminal.

[0116] The second communication information may be communication information such as CAN messages, LIN messages, etc. The signal measurement information may be used to perform positioning analysis on the target terminal. For example, the signal measurement information may be a signal strength indicator (RSSI) or other signal measurement information.

[0117] Step 206: Position the target terminal according to the signal measurement information to obtain positioning information of the target terminal.

[0118] In some embodiments, the method provided in the embodiments of the present application may further perform the following operations:

[0119] The Bluetooth main module receives Bluetooth key control commands sent by different terminals that have been connected to the vehicle through the Bluetooth key; and based on the positioning information of the different terminals, respectively executes vehicle control operations corresponding to the Bluetooth key control commands.

[0120] This embodiment can enable multiple devices (including mobile phones and watches) to be connected to the Bluetooth main module at the same time; among them, the mobile phone and watch can be considered as independent devices for the vehicle-side connection.

[0121] As shown in Figure 6, when actively controlling the vehicle through the Bluetooth slave module, all commands sent by the Bluetooth slave module need to be sent to the XCU adaptation layer. For example, unlocking and locking are sent simultaneously and processed by the Front Body Control Module (FBCM). Corresponding to the control authority, any mobile phone that meets the relevant positioning logic can unlock / lock the keyless entry system (Passive Entry, PE) / charger cover / trunk / start the keyless start system (Passive Start, PS).

[0122] In this embodiment, the positioning and related logic strategies of multiple mobile phones are processed in parallel and by the same software modules. The relevant vehicle control commands and positioning results for each mobile phone are output in real time to the multiple mobile phone logic processing modules. As shown in Figure 7, the logic processing module uniformly processes the coexistence of the positioning of multiple mobile phones and the related vehicle control logic, and then uniformly outputs the summarized positioning information and related vehicle control instructions. For the XCU or other modules, the multiple mobile phone logic processing module can be considered a single-connection logic output module. The output control signals, instructions, and positioning information are for a single-connection digital key. It still outputs the vehicle control and positioning strategies of a single mobile phone, without affecting the current vehicle control logic and instructions of other modules. Furthermore, the number of mobile phones that trigger the vehicle to lock the vehicle, the number of related connections, and the number of mobile phones near the driver's seat are output and observed via CAN signals.

[0123] The technical solution of this embodiment synchronizes the Bluetooth connection information of each mobile phone through CAN signals and sends it to the Bluetooth slave module. The Bluetooth slave module periodically monitors the field strength information of different mobile phones for positioning. Through the XCU BLE logic layer processing, the signals of multiple mobile phones can be synthesized into a total authority and command signal output to the XCU adaptation layer, without affecting the logic processing of other modules of the vehicle. Under multiple connections, Bluetooth broadcast is maintained and the number of connected mobile phones is displayed in the broadcast. After the maximum number of connections is reached, the broadcast is still maintained and the broadcast attribute is modified to be unconnectable. Other authorized mobile phones can detect that the maximum number of connections has been reached after scanning. Among them, the fixed interval of the connection cycle can be x, and the connection interval of multiple mobile phones is the same, and x is an odd number; the control instructions of multiple mobile phones are abstracted into a set of control instructions for synchronous use through the multi-mobile phone logic processing module in the XCU, without affecting other controllers and with minimal development changes; to implement the multi-connection protocol stack, it is necessary to support CAN full-duplex communication.

[0124] The technical solution provided by this embodiment has at least the following technical effects:

[0125] It supports simultaneous positioning of multiple mobile phones when multiple mobile phones are connected to the vehicle at the same time; it supports multiple mobile phones to support passive functions (unlocking by approaching, locking by moving away, powering on by stepping on the brake, etc.) at the same time; multiple mobile phones can be connected at the same time and can execute vehicle control functions at the same time; after multiple keys are connected, the device type field in the keychain information can be used to distinguish between mobile phones and watch devices.

[0126] The technical solution of this embodiment solves the functional defect of the single connection of the traditional Bluetooth key, and has at least the following technical advantages:

[0127] 1. Improved user experience: The multi-connection feature allows users to use the same key on multiple phones, reducing the need for frequent re-pairing and improving the user experience. For example, if multiple family members need to use the same car, the multi-connection feature allows family members to directly use the connected phone without having to re-pair the key each time.

[0128] 2. Enhanced vehicle security: The multi-connection feature allows users to promptly delete or replace connected phones, reducing the risk of information leakage and vehicle theft. For example, if a key is stolen or lost, users can prevent unauthorized access by deleting or replacing the connected phone.

[0129] 3. Reduce operating costs: The multi-connection function allows users to use the same key on different mobile phones, reducing the number of frequent re-pairing operations and reducing users' operating costs and time costs.
