In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] Please refer to Figure 1 , which shows a flow chart of a vehicle diagnosis method provided by an embodiment of the present application. The vehicle diagnosis method can be applied to a vehicle system, the vehicle system includes a vehicle module and a diagnostic information processing module, the vehicle module includes a central control screen, and specifically may include: Step 101, the vehicle module obtains a specified mode startup request, and the central control screen outputs an identity authentication control and a diagnostic control of the diagnostic application of the vehicle module based on the specified mode startup request, and obtains the identity information of the operator based on the identity authentication control, and sends the identity information to the fleet management terminal, so that the fleet management terminal can monitor the vehicle diagnosis process based on the identity information.

[0024] Step 102: The vehicle computer module obtains the operator's operation data on the diagnostic control.

[0025] Step 103: The vehicle computer module sends the operation data to the diagnostic information processing module.

[0026] Step 104: The diagnostic information processing module parses the received operation data to obtain diagnostic instruction information.

[0027] Step 105 : The diagnostic information processing module sends the diagnostic instruction information to the controller of the vehicle to receive diagnostic result information based on the diagnostic instruction information returned by the controller of the vehicle.

[0028] Step 106: The diagnostic information processing module sends the diagnostic result information to the vehicle computer module.

[0029] It should be noted that the vehicle machine module may include a vehicle-mounted portable media player (MPEG Layer 5, MP5).

[0030] It should be noted that the diagnostic information processing module may be a T-BOX. The vehicle system may be a system integrated with the T-BOX.

[0031] It should be noted that the vehicle module may include a central control screen. The diagnostic control may be an operable control output on the central control screen of the vehicle module. The operation data may be generated by an operator triggering the diagnostic control. The triggering operation may include but is not limited to a click operation, a sliding operation, a gesture operation, etc.

[0032] In this way, the operator's operation data on the diagnostic control can be obtained through the vehicle-machine module of the vehicle-machine system, and the operation data can be sent to the diagnostic information processing module of the vehicle-machine system. The diagnostic information processing module parses and processes the received operation data to obtain diagnostic instruction information. The diagnostic information processing module sends the diagnostic instruction information to the controller of the vehicle to receive the diagnostic result information based on the diagnostic instruction information returned by the controller of the vehicle. The diagnostic information processing module sends the diagnostic result information to the vehicle-machine module. Since the diagnostic operation of the vehicle can be performed directly through the interactive processing of the vehicle-machine module and the diagnostic information processing module of the vehicle's own vehicle-machine system, the vehicle diagnosis can be directly completed by using the vehicle's own vehicle-machine system, which can avoid the use of control terminals outside the vehicle to complete the diagnostic operation of the vehicle, thereby optimizing the convenience and flexibility of electric commercial vehicle diagnosis.

[0033] Optionally, in a possible implementation of this embodiment, the diagnostic information processing module may include a pre-processing interface. In step 102, the vehicle machine module sends the operation data to the pre-processing interface via a first protocol.

[0034] In this implementation, the first protocol may include a communication protocol, a Unified Diagnostic Services (UDS) protocol, etc.

[0035] In this implementation, the preprocessing interface may include a software development kit (Software Development Kit, SDK) interface.

[0036] In a specific implementation process of this implementation method, the vehicle machine module sends the operation data to the preprocessing interface through a first communication protocol.

[0037] In a specific implementation process of this implementation method, further, in step 103, first, the preprocessing interface preprocesses the received operation data. Secondly, the preprocessing interface sends the preprocessing result to the diagnostic information processing module. Thirdly, the diagnostic information processing module parses the received preprocessing result. Thirdly, the diagnostic information processing module obtains diagnostic instruction information based on the parsing result.

[0038] In one case of the specific implementation process, the preprocessing interface converts the received operation data to obtain the diagnostic action information corresponding to the operation data. The result of the preprocessing may include the diagnostic action information corresponding to the operation data.

[0039] Furthermore, the diagnostic information processing module parses and processes the diagnostic action information corresponding to the received operation data. Thirdly, the diagnostic information processing module obtains diagnostic instruction information based on the result of the parsing process.

[0040] Another situation of the specific implementation process is that the preprocessing interface sends the preprocessing result to the diagnostic information processing module through a second protocol. Here, the second protocol may include a communication protocol and the like.

[0041] In this way, the pre-processing interface embedded in the diagnostic information processing module can interact with the vehicle computer module, ensuring the flexibility of data exchange and allowing customized development according to actual needs. At the same time, the data transmission between the vehicle computer and the diagnostic information processing module will be encrypted and protected using more secure technologies and protocols, improving the security and reliability of data transmission.

[0042] Optionally, in a possible implementation of this embodiment, in step 104, the diagnostic information processing module sends the diagnostic instruction information to a vehicle body bus, so that the vehicle body bus sends the diagnostic instruction information to a controller of the vehicle.

[0043] Optionally, in a possible implementation of this embodiment, in step 104, first, the controller of the vehicle may obtain the diagnostic identifier of the diagnostic instruction information. Secondly, the controller of the vehicle performs a diagnostic operation based on the diagnostic identifier to obtain diagnostic result information. Thirdly, the controller of the vehicle sends the diagnostic result information to the diagnostic information processing module. Thirdly, the diagnostic information processing module receives the diagnostic result information returned by the controller of the vehicle based on the diagnostic identifier.

[0044] In this implementation, the diagnostic instruction information may include diagnostic services such as reading vehicle / electronic control unit (ECU) fault codes, reading ECU software and hardware version numbers, and executing action test instructions. The diagnostic instruction information may be diagnostic message information.

[0045] Here, the diagnostic identifier may be a diagnostic service identifier. For example, when reading vehicle data, the 22 service in the UDS diagnostic protocol (ISO14229) is used, and the diagnostic service identifier may be "22". The diagnostic instruction information may be "22 FF FF FF FFFF FF FF".

[0046] In this implementation, the diagnostic result information may include a positive response and the result of the diagnostic execution, a negative response, etc. The result of the diagnostic execution may include the read vehicle / ECU fault code, the read ECU software and hardware version number, the completion status of the executed action, etc.

[0047] Here, after the controller correctly receives the diagnostic instruction information, the controller can feedback "62 XX XX XX XX XX XXXX" to the diagnostic information processing module, and the diagnostic information processing module captures the reply message information according to the corresponding diagnostic identifier, that is, the diagnostic result information returned by the controller.

[0048] Optionally, in a possible implementation of this embodiment, the vehicle machine module may further include a central control screen. After step 105, the vehicle machine module outputs the diagnosis result information through the central control screen.

[0049] In a specific implementation process of this implementation method, before step 101, further, the vehicle machine module can obtain a designated mode start request, and then the central control screen outputs the diagnostic control based on the designated mode start request.

[0050] In this implementation, the designated mode may be a vehicle factory mode of the vehicle system.

[0051] In this implementation, the designated mode start request may be generated based on an operator's operation of a hardware button of the vehicle computer.

[0052] One scenario of this specific implementation process is that the vehicle computer module can obtain a specified mode startup request, and then perform identity authentication processing based on the specified mode startup request to obtain verification information. When the verification information meets the preset verification conditions, the central control screen can output the diagnostic control based on the specified mode startup request.

[0053] Another situation of the specific implementation process is that the central control screen outputs an identity authentication control based on the specified mode startup request, and then the central control screen can obtain the identity information of the operator based on the identity authentication control, and send the identity information to the fleet management terminal, so that the fleet management terminal can monitor and process the vehicle diagnosis process based on the identity information.

[0054] Another situation of the specific implementation process is that the central control screen receives the diagnosis termination instruction sent by the fleet management terminal, and terminates the vehicle diagnosis based on the diagnosis termination instruction.

[0055] Optionally, exemplarily, if the diagnosis detects a defect, the vehicle shift mechanism is locked, and a test report needs to be sent to the fleet management terminal for confirmation. After the fleet management terminal sends the confirmation message, the vehicle can be unlocked and drive normally.

[0056] It is understandable that here, the vehicle computer module can also interact with the fleet management terminal, and the vehicle computer module outputs relevant instructions and controls through the central control screen.

[0057] In this way, by outputting the diagnostic control of the diagnostic application when starting in the specified mode, the designated operator is guaranteed to perform the diagnostic operation on the vehicle, thus improving the safety and reliability of vehicle diagnosis. Moreover, the vehicle diagnostic process can be monitored through the fleet management terminal, and diagnostic problems can be dealt with in a timely manner, thereby further improving the safety and reliability of vehicle diagnosis.

[0058] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementation to implement the vehicle diagnosis method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0059] Figure 2 is a schematic diagram of the architecture of a vehicle system provided by another embodiment of the present application. Figure 2 In this embodiment, the vehicle system is applied to an electric commercial vehicle and can be used to execute the vehicle diagnosis method in the aforementioned embodiment. The vehicle system can specifically include a vehicle module and a diagnostic information processing module. The vehicle module includes a central control screen (not shown in the figure).

[0060] The vehicle-mounted computer module may be used to obtain the operator's operation data on the diagnostic control and send the operation data to the diagnostic information processing module; wherein the diagnostic control is a control of the diagnostic application of the vehicle-mounted computer module.

[0061] The central control screen is used to output the identity authentication control and the diagnostic control of the diagnostic application of the vehicle module based on the specified mode startup request, and based on the identity authentication control, obtain the identity information of the operator, and send the identity information to the fleet management terminal, so that the fleet management terminal can monitor the vehicle diagnosis process based on the identity information.

[0062] The diagnostic information processing module can be used to parse and process the received operation data to obtain diagnostic instruction information; send the diagnostic instruction information to the vehicle controller to receive the diagnostic result information based on the diagnostic instruction information returned by the vehicle controller, and send the diagnostic result information to the vehicle computer module.

[0063] Here, the diagnostic information processing module can be T-BOX. The diagnostic information processing module is integrated in the vehicle system. The vehicle system is dominant. Inserting a SIM card enables the vehicle to have the function of a remote control terminal. It can be directly connected to the vehicle through the automobile telematics service provider (Telematics Service Provide, TSP) platform. The vehicle system is also equipped with GPS antenna input and 4G antenna to receive location information and network signals in real time. And the vehicle module and T-BOX can communicate and connect. The vehicle module and T-BOX can share the vehicle system USB external interface, which can meet the vehicle system audio and video entertainment USB resource reading and the T-BOX diagnostic processing resource reading.

[0064] It is understandable that, here, the vehicle module and T-BOX can also be connected using a USB harness.

[0065] Optionally, in a possible implementation of this embodiment, the diagnostic information processing module may include a preprocessing interface. The vehicle computer module may also be used to send the operation data to the preprocessing interface through a first protocol. The preprocessing interface may be used to preprocess the received operation data and send the preprocessing result to the diagnostic information processing module. The diagnostic information processing module may be used to parse the received preprocessing result and obtain diagnostic instruction information based on the parsing result.

[0066] Optionally, in a possible implementation of this embodiment, the vehicle system may further include a vehicle body bus. The diagnostic information processing module may be configured to send the diagnostic instruction information to the controller of the vehicle via the vehicle body bus.

[0067] Optionally, in a possible implementation of this embodiment, the vehicle computer module may include a central control screen, and the vehicle computer module may also be used to output the diagnosis result information through the central control screen.

[0068] Here, the vehicle machine module can also be used to obtain a designated mode start request. Then the central control screen can be used to output the diagnostic control based on the designated mode start request.

[0069] Optionally, in a possible implementation of this embodiment, the diagnostic information processing module may be a T-BOX. The designated mode may be a vehicle machine factory mode.

[0070] In this way, T-BOX is integrated into the vehicle system, and the diagnostic application is implanted into the vehicle factory mode. By setting the entry operation password, it can be configured for operation by vehicle maintenance personnel.

[0071] Figure 3 FIG. 1 is a schematic diagram of the architecture of a vehicle system in an application scenario provided by another embodiment of the present application. Figure 3 As shown, the vehicle computer system may include a vehicle computer, a T-BOX, a SDK interface of the T-BOX, a bus, and various controllers of the vehicle.

[0072] In this embodiment, if Figure 3 As shown, the vehicle computer, that is, the vehicle computer module, can send the soft switch operation data to the SDK interface of the T-BOX through protocol one. The SDK interface can package the actions to be executed and send them to the T-BOX for parsing through protocol two. The actions to be executed can be obtained by converting the soft switch operation data. T-BOX parses the diagnostic instructions and sends the diagnostic instructions to the bus. Each controller receives the diagnostic instructions through the bus. After executing the diagnostic instructions, it can reply to the corresponding diagnostic message to the bus. The diagnostic message may include replying an affirmative response and its corresponding data to the bus, as well as replying a negative response. Send the corresponding diagnostic message to the T-BOX through the bus. T-BOX packages the received data and sends the data to the SDK interface through protocol two. The SDK interface sends the data to the vehicle computer through protocol one.

[0073] In this embodiment, if Figure 3As shown in the figure, protocol 1 is the protocol for the interaction between the vehicle computer and the SDK, which is used to convert the soft switch operation data on the vehicle computer into the data received by the SDK, that is, the diagnostic action to be performed. Protocol 2 is the protocol required for data transmission between the SDK and the T-BOX, which is used to package the diagnostic action to be performed into a data packet and send it to the T-BOX. The T-BOX parses the data packet to obtain the diagnostic instruction information. The diagnostic instruction information, that is, the operation supported by the active diagnosis, can include reading the vehicle / ECU fault code, reading the ECU software and hardware version number, executing the action test instruction, etc. The T-BOX can send the diagnostic instruction information to each controller to obtain the diagnostic result information. For example, according to the UDS diagnostic protocol, when reading vehicle data, the 22 service is used. After the T-BOX sends the diagnostic message "22 FF FF FF FF FF FF FF" to the bus, the corresponding controller receives it. After correct reception, the controller replies "62 XX XX XX XX XX XX XX" to the bus, and the T-BOX captures the message according to the corresponding message identifier. After T-BOX packages the captured messages, it sends the packaged data to SDK through protocol 2. SDK parses the packaged data after receiving it, and transmits the parsed data to the vehicle computer through protocol 1. The central control screen of the vehicle computer can display the corresponding diagnostic result information, such as the vehicle / ECU fault code, the ECU software and hardware version number, and whether the action operation instruction is completed.

[0074] In this embodiment, T-BOX is integrated into the vehicle system, with the vehicle system as the main body, and a SIM card is inserted, so that the vehicle system has the function of a remote control terminal, and the vehicle system can be directly connected to the TSP platform. The vehicle system is equipped with a GPS antenna and a 4G antenna at the same time, which receives location information and network signals in real time. This solution can reduce the use of USB cables between T-BOX and the vehicle module, and the vehicle module and T-BOX share the vehicle USB external interface, which can not only meet the vehicle system audio and video entertainment USB resource reading, but also meet the T-BOX on-board diagnostic function. Software calibration and software update resources in the diagnostic service can be obtained through the vehicle USB external interface.

[0075] Here, the vehicle computer module can run diagnostic applications to communicate and exchange data with the T-BOX. Custom development can be carried out according to actual needs, and the data transmission between the vehicle computer and the T-BOX will be encrypted and protected using more secure technologies and protocols.

[0076] It is understandable that based on the importance of the diagnostic application to the whole vehicle, this diagnostic application can be set in the vehicle factory mode. R&D and debugging personnel can enter the vehicle factory mode in a set manner to operate the diagnostic application and perform vehicle diagnostic processing, such as reading the vehicle configuration information and the vehicle fault code. The diagnostic application is implemented based on the UDS diagnostic function supported by the vehicle controller and meets the ISO14229 and ISO15765 diagnostic protocols. The diagnostic application can implement the vehicle diagnostic function based on different diagnostic services. For example, the 22 service can read the vehicle configuration information, the controller software and hardware version number, etc.; the 2E service can change the vehicle configuration, such as changing the vehicle VIN code information, controller calibration, etc.

[0077] By adopting the solution in this embodiment, the T-BOX can be integrated into the vehicle system, thereby improving the vehicle's intelligence level and optimizing the vehicle's diagnostic processing method, allowing developers and after-sales service personnel to use the diagnostic instrument based on the vehicle system in a timely and accurate manner to understand the vehicle information. At the same time, the vehicle system directly performs operations such as software calibration and software updates, thereby enhancing the user experience.

[0078] By adopting the solution in this embodiment, the vehicle computer module can run the diagnostic application to communicate and exchange data with the SDK interface of the T-BOX, ensuring the flexibility of data exchange and allowing customized development according to actual needs. At the same time, the data transmission between the vehicle computer and the diagnostic information processing module will be encrypted and protected using more secure technologies and protocols, improving the security and reliability of data transmission.
