[0019] The vehicle infotainment module determines whether it detects message information from the TBOX module.

[0020] Upon detecting message information from the TBOX module, authenticate the TBOX module.

[0021] If the TBOX module is identified as the target TBOX module, the first communication method is disconnected, and the existence of the second communication method is identified.

[0022] In this embodiment, the vehicle infotainment module includes a first communication unit and a first microcontroller unit that communicate with each other, and the TBOX module includes a second communication unit and a second microcontroller unit that communicate with each other.

[0042] Figure 1 A flowchart illustrating a method for vehicle-mounted module compatibility according to an embodiment of this application is shown schematically. Figure 1 As shown in the embodiments of this application, a method for vehicle module compatibility is provided, applied to a vehicle module compatibility system. The vehicle module compatibility system may include a vehicle infotainment module and a TBOX module, which are connected on the same bus. The vehicle infotainment module uses a first communication method, and the TBOX module uses a second communication method. The method may include the following steps:

[0043] Step 101: Determine whether the message information from the TBOX module is detected through the vehicle infotainment module;

[0044] Step 102: Upon detecting the message information of the TBOX module, authenticate the TBOX module;

[0045] Step 103: If the TBOX module is determined to be the target TBOX module, disconnect the first communication method and mark the existence of the second communication method.

[0046] The vehicle module compatibility method of this application embodiment is applied to an vehicle module compatibility system, which may include a vehicle infotainment module and a TBOX module connected to the same bus. The vehicle infotainment module and the TBOX module communicate using different methods: the vehicle infotainment module uses a first communication method, and the TBOX module uses a second communication method. For example, the vehicle infotainment module may use 4G communication, and the TBOX module may use 5G communication. It should be noted that the first and second communication methods in this application embodiment represent two different communication methods, which may include, but are not limited to, the aforementioned 4G and 5G communication methods, or any two different communication methods. The vehicle infotainment module and the TBOX module can be connected to the same bus. In one example, the vehicle infotainment module and the TBOX module can be connected to the same bus via a Controller Area Network (CAN) network, and the vehicle infotainment module and the TBOX module can respectively send their respective message information to the CAN bus.

[0047] In this embodiment, since the vehicle infotainment module and the TBOX module are connected to the same bus, when the TBOX module sends a message, the vehicle infotainment module can detect the message from the TBOX module. At this time, the vehicle infotainment module needs to disable its built-in first communication mode to avoid network IP and service conflicts caused by simultaneously enabling two communication modes. However, external TBOX modules may not be legitimate optional TBOX modules, posing a threat to the vehicle system's security. Therefore, before disabling the built-in first communication mode, the vehicle infotainment module needs to authenticate the TBOX module to determine if it is a legitimate optional TBOX, thereby improving system security. In this embodiment, the target TBOX module is the legitimate optional TBOX module. When the vehicle infotainment module detects the message from the TBOX module, it authenticates the TBOX module. If the TBOX module is determined to be the target TBOX module, the vehicle infotainment module disconnects its own first communication mode and identifies the existence of a second communication mode to remind the operator that the current communication mode is the TBOX module's communication mode.

[0048] In this embodiment, the vehicle infotainment module and the TBOX module are connected to the same bus. The vehicle infotainment module uses a first communication method, and the TBOX module uses a second communication method. First, the vehicle infotainment module determines whether it detects message information from the TBOX module. If it does, it authenticates the TBOX module. Then, if the TBOX module is identified as the target TBOX module, the first communication method is disconnected, and the existence of the second communication method is indicated. In this way, even if the vehicle has multiple communication methods, the vehicle infotainment module can automatically select the appropriate method based on the actual situation, thereby eliminating IP and service conflicts between multiple communication methods and improving the vehicle's communication efficiency and security.

[0049] In this embodiment, the vehicle infotainment module may include a first communication unit and a first microcontroller unit that communicate with each other, and the TBOX module may include a second communication unit and a second microcontroller unit that communicate with each other. The first microcontroller unit and the second microcontroller unit are connected via a bus. The method may further include:

[0050] When the vehicle infotainment module is powered on, the first microcontroller sends the first message to the bus;

[0051] When the TBOX module is powered on, the second microcontroller sends a second message to the bus.

[0052] The first message includes a first ID, the second message includes a second ID, and the first ID and the second ID have different prefixes.

[0053] In this embodiment, the first microcontroller unit (MCU) is the MCU of the vehicle infotainment module, and the second microcontroller unit is the MCU of the TBOX module. The vehicle infotainment module may include a first communication unit and the first microcontroller unit that communicate with each other. The TBOX module may include a second communication unit and the second microcontroller unit that communicate with each other. The first and second microcontroller units are connected via a bus and can send their respective message information to the CAN bus. When the vehicle infotainment module is powered on, the first microcontroller unit can send a first message to the bus, which is the message information of the vehicle infotainment module. When the TBOX module is powered on, the second microcontroller unit can send a second message to the bus, which is the message information of the TBOX module. To distinguish between the first and second messages, different ID prefixes can be set for the first and second messages. Therefore, in this embodiment, the first ID prefix and the second ID prefix are different. For example, the first ID can start with 123, such as 01 23 00 00 00 00 00 000011, and the second ID can start with 456, such as 04 56 00 00 00 00 00 00 00 22. In this way, different message information can be distinguished by the ID prefix.

[0054] In this embodiment of the application, step 101, determining whether the message information of the TBOX module is detected by the vehicle-mounted module, includes:

[0055] The first microcontroller unit monitors the message information on the bus;

[0056] If the detected message information includes the second ID, it is determined that the vehicle infotainment module has detected the message information from the TBOX module.

[0057] Specifically, since the first microcontroller unit and the second microcontroller unit are connected to the same bus, the first microcontroller unit can send a first message to the bus and also monitor the message information on the bus in real time. If the first microcontroller unit detects a message on the bus that includes a second ID prefix, it indicates that a second message sent by the TBOX module is present on the bus. Therefore, it can be determined that a message from the TBOX module has been detected. Using different ID prefixes to determine the presence of a TBOX module message facilitates timely judgment of the communication method by the vehicle's infotainment system, improving monitoring efficiency.

[0058] In this embodiment of the application, the method may further include:

[0059] If no message information from the TBOX module is detected, maintain the first communication mode.

[0060] Specifically, if the first microcontroller does not detect the message information of the TBOX module, that is, if the first microcontroller does not detect the second ID prefix, it can be determined that only one communication method exists at this time. Therefore, the vehicle module can continue to maintain the first communication method.

[0061] In this embodiment, the vehicle infotainment module and the TBOX module are connected to the same bus via a CAN network.

[0062] Specifically, the data communication between nodes in a CAN network has strong real-time performance, a short development cycle, and can achieve free and unrestricted communication. Therefore, the vehicle module and the TBOX module can be connected to the same bus through the CAN network and send CAN messages to the bus.

[0063] Figure 2 This diagram schematically illustrates a structural diagram of an in-vehicle module compatible system according to an embodiment of this application. Figure 2 As shown, in one embodiment of this application, an in-vehicle module compatible system is provided. The in-vehicle module compatible system includes a vehicle infotainment module 200 and a TBOX module 300, which are connected to the same bus. The communication method of the vehicle infotainment module 200 is a first communication method, and the communication method of the TBOX module 300 is a second communication method. The in-vehicle module compatible system can be configured as follows:

[0064] The vehicle infotainment module 200 determines whether it detects message information from the TBOX module 300.

[0065] Upon detecting message information from the TBOX module 300, authenticate the TBOX module 300.

[0066] If the TBOX module 300 is identified as the target TBOX module, the first communication method is disconnected, and the existence of the second communication method is identified.

[0067] This application provides an in-vehicle module compatible system, which may include a vehicle infotainment module 200 and a TBOX module 300 connected to the same bus. The vehicle infotainment module 200 and the TBOX module 300 use different communication methods. The vehicle infotainment module 200 uses a first communication method, while the TBOX module 300 uses a second communication method. For example, the vehicle infotainment module 200 may use 4G communication, and the TBOX module 300 may use 5G communication. It should be noted that the first and second communication methods in this application represent two different communication methods, which may include, but are not limited to, the aforementioned 4G and 5G communication methods, or any two different communication methods. The vehicle infotainment module 200 and the TBOX module 300 can be connected to the same bus. In one example, the vehicle infotainment module 200 and the TBOX module 300 can be connected to the same bus via a CAN network, and the vehicle infotainment module 200 and the TBOX module 300 can each send their respective message information to the CAN bus.

[0068] In this embodiment, since the vehicle infotainment module 200 and the TBOX module 300 are connected to the same bus, when the TBOX module 300 sends a message, the vehicle infotainment module 200 can detect the message from the TBOX module 300. At this time, the vehicle infotainment module 200 needs to disable its built-in first communication mode to avoid network IP and service conflicts caused by simultaneously enabling two communication modes. However, the external TBOX module 300 may not be a legitimate optional TBOX module, posing a threat to the security of the vehicle system. Therefore, before disabling the built-in first communication mode, the vehicle infotainment module 200 also needs to perform authentication on the TBOX module 300 to determine whether the current TBOX module 300 is a legitimate optional TBOX, thereby improving system security. In this embodiment of the application, the target TBOX module is a legitimate optional TBOX module. When the vehicle module 200 detects the message information of the TBOX module 300, it authenticates the TBOX module 300. If it determines that the TBOX module 300 is the target TBOX module, it disconnects the first communication mode of the vehicle module 200 itself and marks the existence of a second communication mode to remind the operator that the current communication mode is the communication mode of the TBOX module 300.

[0069] In this embodiment, the vehicle infotainment module 200 and the TBOX module 300 are connected to the same bus. The vehicle infotainment module 200 uses a first communication mode, and the TBOX module 300 uses a second communication mode. First, the vehicle infotainment module 200 determines whether it detects message information from the TBOX module 300. If message information from the TBOX module 300 is detected, the TBOX module 300 is authenticated. Then, if the TBOX module 300 is identified as the target TBOX module, the first communication mode is disconnected, and the existence of the second communication mode is indicated. In this way, even if the vehicle has multiple communication modes, the vehicle infotainment module 200 can automatically select the appropriate communication mode according to the actual situation, thereby eliminating IP and service conflicts between multiple communication modes and improving the vehicle's communication efficiency and security.

[0070] Figure 3 A schematic diagram illustrating the structure of a vehicle-mounted module compatible system according to another embodiment of this application is shown. Figure 3 As shown, in another embodiment of this application, the vehicle module 200 may include a first communication unit 201 and a first microcontroller unit 202 that communicate with each other, and the TBOX module 300 may include a second communication unit 301 and a second microcontroller unit 302 that communicate with each other. The first microcontroller unit 202 and the second microcontroller unit 302 are connected via a bus. The vehicle module compatible system can also be configured as follows:

[0071] When the vehicle infotainment module 200 is powered on, the first microcontroller unit 202 sends a first message to the bus;

[0072] When the TBOX module 300 is powered on, the second microcontroller unit 302 sends a second message to the bus.

[0073] The first message includes a first ID, the second message includes a second ID, and the first ID and the second ID have different prefixes.

[0074] In this embodiment, the first microcontroller unit 202 is the MCU of the vehicle infotainment module, and the second microcontroller unit 302 is the MCU of the TBOX module. The vehicle infotainment module 200 may include a first communication unit 201 and a first microcontroller unit 202 that communicate with each other. The TBOX module 300 may include a second communication unit 301 and a second microcontroller unit 302 that communicate with each other. The first microcontroller unit 202 and the second microcontroller unit 302 are connected via a bus, and can send their respective message information to the CAN bus. When the vehicle infotainment module 200 is powered on, the first microcontroller unit 202 can send a first message to the bus, which is the message information of the vehicle infotainment module. When the TBOX module 300 is powered on, the second microcontroller unit 302 can send a second message to the bus, which is the message information of the TBOX module 300. To distinguish between the first message and the second message, different ID prefixes can be set for the first message and the second message. Therefore, in this embodiment, the first ID prefix and the second ID prefix are different. For example, the first ID can start with 123, such as 01 23 00 00 00 00 00 00 00 11, and the second ID can start with 456, such as 04 56 00 00 0000 00 00 00 22. In this way, different message information can be distinguished by the starting ID.

[0075] like Figure 3 As shown in the embodiments of this application, the vehicle module compatibility system can also be configured as follows:

[0076] The first microcontroller unit 202 monitors the message information on the bus;

[0077] If the detected message information includes the second ID, it is determined that the vehicle infotainment module has detected the message information of the TBOX module 300.

[0078] Specifically, since the first microcontroller unit 202 and the second microcontroller unit 302 are connected to the same bus, the first microcontroller unit 202 can send a first message to the bus and also monitor the message information on the bus in real time. If the first microcontroller unit 202 detects that the message information on the bus includes a second ID prefix, it indicates that a second message sent by the TBOX module 300 exists on the bus. Therefore, it can be determined that message information from the TBOX module 300 is being monitored at this time. Determining the presence of TBOX module 300 message information by using different ID prefixes facilitates timely judgment of the communication method by the vehicle infotainment module 200, improving monitoring efficiency.

[0079] In this embodiment of the application, the vehicle module compatibility system can also be configured as follows:

[0080] If no message information is detected from the TBOX module 300, maintain the first communication mode.

[0081] Specifically, if the first microcontroller unit 202 does not detect the message information of the TBOX module 300, that is, if the first microcontroller unit 202 does not detect the second ID prefix, it can be determined that there is only one communication method at this time. Therefore, the vehicle module 200 can continue to maintain the first communication method.
