[0048] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] This embodiment provides a processing method based on a Bluetooth key. The execution subject corresponding to 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 end side of a domain controller (XCU). Figure 1 As shown, the method includes:

[0050] Step 101: Obtain the number of terminals currently connected to the vehicle via the Bluetooth key.

[0051] The terminals that the vehicle is currently connected to with the Bluetooth key can be considered as the vehicle having successfully connected to these terminals with the Bluetooth key. This embodiment can realize multiple connections of the vehicle Bluetooth key and can record the number of terminals currently connected to the vehicle via the Bluetooth key in real time.

[0052] It should be noted that the equivalent description of the Bluetooth key involved in this embodiment may include: Bluetooth digital key, digital key, etc. The terminal involved in this embodiment, that is, the terminal supporting the Bluetooth key function, may be a smart phone, a smart watch, a tablet computer, etc., and this embodiment does not make specific limitations.

[0053] Step 102: If the number of terminals currently connected to the vehicle via the Bluetooth key is less than a preset threshold, a first connectable Bluetooth broadcast is sent through the Bluetooth main module of the vehicle.

[0054] The preset threshold is greater than or equal to 2, and the preset threshold can be used to determine the maximum number of terminals connected to 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 terminals connected to the vehicle for Bluetooth key connection is 3; if the preset threshold is 6, the maximum number of terminals connected to the vehicle for Bluetooth key connection is 6.

[0055] 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 via the Bluetooth key is less than a preset threshold, it means that other terminals can be connected, and the BLE main module may periodically send a connectable first Bluetooth broadcast, so that other terminals can connect to the Bluetooth key according to the first Bluetooth broadcast. The broadcast type of the first Bluetooth broadcast may be a discoverable and connectable type.

[0056] Step 103: Receive, through the Bluetooth main module, a Bluetooth key connection request initiated by the target terminal according to the first Bluetooth broadcast.

[0057] The target terminal may be a terminal that needs to be connected to the Bluetooth key, except for the terminal that is currently connected to the Bluetooth key.

[0058] For this embodiment, encryption and decryption authentication can be performed according to 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 XCU via a vehicle controller area network (Controller Area Network, CAN) message, and the XCU performs encryption and decryption authentication based on the keychain information, wherein 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.

[0059] Step 104: When it is determined that the Bluetooth master module is successfully connected to the target terminal Bluetooth key, the Bluetooth connection information corresponding to the Bluetooth master module is synchronized to each Bluetooth slave module.

[0060] The Bluetooth connection information may include access address, cyclic redundancy check code (CRC) initial value, connection interval, frequency hopping channel map (Channel Map) and other information.

[0061] 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 according to the Bluetooth connection information, and then measure the field strength information of the terminal to facilitate the positioning of the terminal. The Bluetooth slave module can be a BLE slave module. For example, Figure 2 , which is an example diagram of the architecture involved in the method of this embodiment, wherein CANFD is an upgraded version of the CAN protocol. XCU can be connected to a BLE master module and multiple BLE slave modules.

[0062] If the same connection period is used to schedule connection monitoring for these 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. In this embodiment, different connection periods are used to schedule connection monitoring for these terminals connected to the Bluetooth key, so that effective positioning of terminals connected to multiple Bluetooth keys can be achieved.

[0063] Compared with the current existing technology, 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 on multiple terminals to control the vehicle, avoiding frequent re-pairing, reducing the user's operating burden and time cost, and improving the user's experience.

[0064] The multi-connection solution of the car Bluetooth key provided in this embodiment may have the following advantages (but not limited to these):

[0065] Improved convenience: The multi-connection function allows users to use the same key on multiple mobile phones, avoiding frequent re-pairing and improving the user experience. For example, if multiple people in a family need to use the same car, the multi-connection function allows them to directly use the connected mobile phone without having to re-pair the key every time.

[0066] Enhanced security: The multi-connection function allows users to delete or replace connected phones in a timely manner, reducing the risk of information leakage and vehicle theft. For example, if the key is stolen or lost, the user can prevent unauthorized persons from gaining access to the car door by deleting the connected phone.

[0067] Improve flexibility: The multi-connection function allows users to switch to different mobile phones at any time, making it easier for users to use the vehicle in different scenarios. For example, users can connect the key with a work phone at work and connect the key with a personal phone at home without having to switch pairs frequently.

[0068] The usage scenarios of the method of this embodiment may include the following (but not limited to):

[0069] 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.

[0070] 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.

[0071] Rental Services: Multi-connection capabilities allow rental service companies to manage vehicle access rights and control vehicle access rights during the rental period.

[0072] Further, as a refinement and extension of the above embodiment, in order to illustrate the specific implementation process of the method of this embodiment, the following is given: Figure 3 The specific methods shown are as follows: Figure 3 As shown, the method includes:

[0073] Step 201: Obtain the number of terminals currently connected to the vehicle via the Bluetooth key.

[0074] Step 202: If the number of terminals currently connected to the vehicle via the Bluetooth key is less than a preset threshold, a first connectable Bluetooth broadcast is sent through the Bluetooth main module of the vehicle.

[0075] The preset threshold is greater than or equal to 2. For ease of understanding, this embodiment is mainly described by taking the terminal being a mobile phone, the preset threshold being 3, the Bluetooth master module being a BLE master module, and the Bluetooth slave module being a BLE slave module as an example.

[0076] In this embodiment, the broadcast period of the Bluetooth main module can be Xms, and the X value can be modified and set according to the actual situation. 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 that the maximum number of connections has been reached based on the feature data and that the Bluetooth key connection can no longer be made. At this time, the mobile phone may not initiate the Bluetooth key connection process to save resource consumption. When the number of connections is less than 3, the broadcast type is a discoverable and connectable type, which is convenient for other mobile phones to connect to the Bluetooth key.

[0077] In some embodiments, the first Bluetooth broadcast may carry the number of terminals that the vehicle is currently connected to via the Bluetooth key. Furthermore, the first Bluetooth broadcast may also carry the number of remaining connected terminals, etc. For example, a certain byte in the Major Value in the ibeacon broadcast definition is used to indicate the number of connected mobile phones. In this way, the mobile phone can clearly know that a Bluetooth key connection is still available, which facilitates the determination of the process of initiating a Bluetooth key connection.

[0078] 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. Other authorized terminal devices can be informed after scanning that the maximum number of connections has been reached, etc.

[0079] Step 203: Receive, through the Bluetooth main module, a Bluetooth key connection request initiated by the target terminal according to the first Bluetooth broadcast.

[0080] For example, the mobile phone determines that the process of initiating Bluetooth key connection can be initiated based on Bluetooth broadcast, and then sends a corresponding Bluetooth key connection request to request Bluetooth key connection. The request may carry connection information, such as keychain information used for encryption and decryption authentication. The BLE main module transparently transmits the connection information to the XCU through multi-frame CAN messages, and the XCU transparently transmits the connection information to the BLE main module through multi-frame CAN messages, and 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 transparent transmission of other mobile phones can still use the same multi-frame CAN message for interaction.

[0081] Step 204: When it is determined that the Bluetooth master module is successfully connected to the target terminal Bluetooth key, 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.

[0082] The first communication information carries the identifier of the target terminal. In this embodiment, different communication information is used for different terminals to synchronize the Bluetooth slave module of the Bluetooth connection information. The Bluetooth slave module can be used to perform time-sharing connection monitoring scheduling according to the different connection cycles of the terminals connected to each Bluetooth key.

[0083] The first communication information may be communication information such as a CAN message, a Local Interconnect Network (LIN) message, etc. The following mainly uses the first communication information being a CAN message as an example for explanation.

[0084] For example, Figure 4As shown, 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 can perform time-sharing connection monitoring scheduling according to the different connection cycles of the mobile phone connected to each Bluetooth key according to the Bluetooth connection information, and then measure the field strength information of each mobile phone to facilitate the positioning of each mobile phone.

[0085] For example, when connecting to the first mobile phone (Phone 1), the Bluetooth connection information of the first mobile phone is synchronized to the BLE slave module through multi-frame CAN message 1 (including the Bluetooth connection information such as the access address of the Bluetooth monitoring connection data channel of the first mobile phone);

[0086] When connecting to the second mobile phone (Phone2), the Bluetooth connection information of the second mobile phone is synchronized to the BLE slave module through multi-frame CAN message 2 (including the Bluetooth connection information such as the access address of the data channel of the second mobile phone Bluetooth monitoring connection);

[0087] When connecting to a third mobile phone (Phone 3), the Bluetooth connection information of the third mobile phone is synchronized to the BLE slave module through multi-frame CAN message 3 (such as Bluetooth connection information including the Bluetooth monitoring connection data channel access address of the third mobile phone).

[0088] In this embodiment, for mobile phones connected to different Bluetooth keys, there may be corresponding CAN messages, and then the BLE slave module of Bluetooth connection information is synchronized through the corresponding CAN messages. For example, the corresponding relationship of CAN messages is that CAN message 1 is used for the synchronization of the BLE slave module of Bluetooth connection information for the first connected mobile phone, which is used to measure the field strength 1 of the first connected mobile phone through the BLE slave module; CAN message 1 is used for the synchronization of the BLE slave module of Bluetooth connection information for the second connected mobile phone, which is used to measure the field strength 2 of the second connected mobile phone through the BLE slave module; CAN message 3 is used for the synchronization of the BLE slave module of Bluetooth connection information for the third connected mobile phone, which is used to measure the field strength 3 of the third connected mobile phone through the BLE slave module.

[0089] 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: in the process of authenticating 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. In some examples, if the keychain information is consistent with the keychain information corresponding to the terminal connected by the Bluetooth key, the identification of the target terminal is determined based on the fields in the keychain information and in combination with the device type of the target terminal.

[0090] For example, the car owner can share the Bluetooth key with other users. After the Bluetooth key is shared, it can support up to three mobile phones to be connected at the same time when one mobile phone is connected. All three mobile phones have unlocking and car control functions, which can realize the scenario where multiple Bluetooth keys are valid at the same time, and after the valid key gets out of the car, the valid key in the car is still unaffected and the vehicle can continue to be used. It also meets the requirements that multiple mobile phones have control over a car at the same time, and all Bluetooth keys have equal connection rights. It supports the state of three shared Bluetooth keys being connected at the same time. After connecting three mobile phones, the broadcast is not turned off, and the broadcast is changed to discoverable but not connectable. The fourth step mobile phone connection is not allowed, and the special broadcast field is changed to specific content, indicating that the maximum number of connections has been reached, and there is no scenario of account crowding.

[0091] In order to clarify the corresponding relationship between connected devices. The owner's account is account 1; the first shared user is account 2; the second shared user is account 3, etc. For example, XCU uses the specific field in the keychain information released by the server to distinguish which account ID is connected. The CAN signal with a specific label sent by XCU to CAN, all signals with multiple connection numbers need to correspond to the information of the specific field of the server to clarify which specific mobile phone is connected to the vehicle and perform related vehicle control operations. In some application scenarios, since the Bluetooth key of the watch is shared to the watch by the mobile phone, the keychain of the watch is consistent with the shared mobile phone. After the watch is connected, XCU uses the device type in the Bluetooth keychain to distinguish. It should be noted that the multi-connection CAN message with serial number sent by the BLE end may only be related to the order of mobile phone connection, and has nothing to do with the mobile phone ID connection.

[0092] In this embodiment, for the multi-connection transparent transmission BLE controller, the CAN protocol stack needs to support full-duplex function, optimize the multi-link function, and ensure that it cannot be interrupted during the sending and receiving processes of multiple frames.

[0093] After receiving the synchronization message, the BLE slave module waits for the communication signal of 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.

[0094] The connection period of the BLE main module for Phone1 is Nms (N is the connection period interval); the connection period of the BLE main module for Phone2 is (N+x)ms (N is the connection period interval); the connection period of the BLE main module for Phone3 is (Nx)ms, where the connection periods are fixed values ​​and x is an odd number. Figure 5As shown, taking x as 5ms as an example, the connection period of the BLE main module for Phone1 is Nms; the connection period of the BLE main module for Phone2 is (N+5)ms (N is the connection period interval); the connection period of the BLE main module for Phone3 is (N-5)ms, where the connection periods are fixed values, and the interval between each of the three mobile phones is 5ms.

[0095] 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.

[0096] In some embodiments, when 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: adding 1 to the number of terminals currently connected to the Bluetooth key; if the number of terminals connected to the vehicle via the Bluetooth key after adding 1 is greater than or equal to the preset threshold, sending a second Bluetooth broadcast that cannot be connected through the Bluetooth main module. Further optionally, the second Bluetooth broadcast carries a prompt message that the Bluetooth key has reached the maximum number of connections.

[0097] 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 maximum number of connections has been reached and the Bluetooth key connection is no longer possible. At this time, the mobile phone may not initiate the Bluetooth key connection process to save resource consumption.

[0098] Step 205: Receive second communication information respectively sent by each Bluetooth slave module, where 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.

[0099] The second communication information may be communication information such as CAN message, LIN message, 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 indication (RSSI) or other signal measurement information.

[0100] Step 206: Position the target terminal according to the signal measurement information to obtain positioning information of the target terminal.

[0101] In some embodiments, a Bluetooth key control command sent by different terminals connected to the vehicle via a Bluetooth key is received through a Bluetooth main module; and based on the positioning information of the different terminals, vehicle control operations corresponding to the Bluetooth key control command are respectively executed.

[0102] This embodiment can realize the simultaneous connection of multiple devices (including mobile phones and watches); mobile phones and watches are considered as independent devices for the vehicle-side connection. For active vehicle control, there is no restriction, and all commands need to be sent to the XCU adaptation layer, such as unlocking and locking sent at the same time to be processed by the front body control module (FBCM). For the corresponding control authority, any mobile phone that meets the relevant positioning logic can start the keyless entry system (Passive Entry, PE) unlocking / locking / charging cover / trunk / keyless start system (Passive Start, PS).

[0103] For this embodiment, the positioning and related logic strategies of multiple mobile phones are processed by parallel and identical software modules, and the relevant vehicle control commands and positioning results of each mobile phone are output to the logic processing modules of multiple mobile phones in real time. Figure 6 and Figure 7 As shown, the logic processing module uniformly handles the coexistence of multiple mobile phone positioning and related vehicle control logic, and then uniformly outputs the summarized positioning information and related vehicle control instructions. For XCU or other modules, the multiple mobile phone logic processing module can be considered as a single-connection logic output module. The output control signal, instruction and positioning information are for a single-connection digital key. It still outputs the vehicle control and positioning strategy of a mobile phone, which does not affect the current vehicle control logic and instructions of other modules at all. The signals such as the number of mobile phones that trigger the vehicle to lock and the number of related connections, and the mobile phones close to the main driver are observed through CAN signal output.

[0104] The technical solution of this embodiment synchronizes the Bluetooth connection information of each mobile phone through CAN signals to the Bluetooth slave module, and 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, which does not affect the logic processing of other modules of the vehicle. Maintain Bluetooth broadcasting under multiple connections and display the number of connected mobile phones in the broadcast. After reaching the maximum number of connections, the broadcast is still maintained, and the broadcast is modified to a non-connectable attribute. Other authorized mobile phones can know after scanning that the maximum number of connections has been reached. Among them, the fixed interval of the connection cycle can be x, the connection intervals of multiple mobile phones are the same, and x is an odd number. Through the multiple mobile phone logic processing module in the XCU, the control instructions of multiple mobile phones are abstracted into a set of control instructions for synchronization, which does not affect other controllers and is developed with minimal changes. In order to realize the multi-connection protocol stack, it is necessary to support CAN full-duplex communication.

[0105] The technical solution provided in this embodiment can have the following technical effects (but not limited to):

[0106] Supports simultaneous positioning of multiple mobile phones when multiple mobile phones are connected to the vehicle at the same time. Supports multiple mobile phones to support passive functions (unlock when approaching, lock when far away, power on by braking, etc.) at the same time. Multiple mobile phones can be connected at the same time and can perform vehicle control functions at the same time. After multiple keys are connected, the device type field in the keychain is used to distinguish between mobile phones and watch devices.

[0107] The technical solution of this embodiment solves the functional defects of the traditional Bluetooth key with single connection. The main improvements are as follows (but not limited to):
