Description of the Drawings

[0029] Figure 1 It is a framework diagram of the vehicle diagnosis system described in the present application.

[0030] Figure 2 It is a flowchart of the vehicle diagnosis method described in the present application. Detailed Embodiments

[0031] The following further describes in detail a vehicle diagnosis system, method, storage medium, and vehicle according to the present application in conjunction with specific embodiments and the accompanying drawings.

[0032] Please refer to Figure 1 , the present application provides a vehicle diagnosis system, which at least includes a main management module deployed on any one domain controller and slave management modules deployed on each domain controller; the main management module is used to communicate with each slave management module based on a wireless link to collect the status information of the corresponding domain controller collected by each slave management module, and perform diagnostic analysis on each domain controller based on the status information to obtain a diagnostic result; wherein, the slave management module is further used to store the collected status information when detecting an abnormality in the wireless link, so as to transmit the stored status information to the main management module after the wireless link returns to normal.

[0033] In some embodiments, it is assumed that the current vehicle includes a central gateway domain controller, an intelligent driving domain controller, and an intelligent cockpit domain controller; the main management module and the slave management module are deployed on the central gateway domain controller, and the slave management modules are also respectively deployed on the intelligent driving domain controller and the intelligent cockpit domain controller.

[0034] Among them, each domain controller forms an Ethernet local area network through a switch.

[0035] Specifically, the main management module collects the health status and operation status (i.e., the status information) in each domain controller through the cross-domain communication interface with the slave management module, including but not limited to the resource usage, task execution, and fault occurrence of each domain controller or module, etc., and analyzes the collected health status and operation status, and judges the status of each domain controller or module, such as normal, abnormal, faulty, etc., according to preset rules and algorithms, and then generates corresponding diagnostic results.

[0036] The slave management module regularly or on demand collects the health status and operation status of the domain controller and its modules through the intra-domain communication interface; if the slave management module detects that the Ethernet communication link (i.e., the wireless link) with the main management module is disconnected, it saves the fault information to the local database file, and waits for the communication link to recover, and then sends the fault information in the local database file to the main management module again.

[0037] It should be noted that the main management module is not necessarily only deployed on the central gateway domain controller, and those skilled in the art can also deploy the main management module on other domain controllers according to actual application requirements, and are not limited thereto.

[0038] Furthermore, the system further includes an interaction module, which is deployed on any domain controller with interaction functions, or on the host computer or in the cloud; the interaction module communicates with the main management module based on a wireless link.

[0039] In some embodiments, the interaction module is usually deployed on the intelligent cockpit domain controller, and can also be deployed on other domain controllers with interaction capabilities, or on the host computer or in the cloud.

[0040] The communication between each domain controller can adopt different gateway communication protocols according to requirements, such as DDS (Data Distribution Service), SOME / IP (Scalable service-Oriented MiddlewarE over IP), ZMQ (ZeroMQ), and so on.

[0041] Among them, DDS is suitable for applications with high real-time requirements and a large amount of dynamically changing data; SOME / IP is a communication protocol widely used in the automotive industry, which supports service discovery, security, and QoS features, and is suitable for complex automotive networks; ZMQ provides a flexible message transmission mechanism and can operate efficiently in various network environments and platforms; those skilled in the art can select a suitable gateway communication protocol according to actual application requirements, or can also select other types of protocols, and are not limited thereto.

[0042] In the above technical solution, the interaction module provides a visual interface, which is convenient for users to monitor and view the situation of each domain controller or module in real time; the addition of the interaction module not only improves the intelligence level of the vehicle diagnostic system, but also enhances the reliability and user-friendliness of the system, bringing significant convenience and benefits to vehicle maintenance and management.

[0043] Among them, the deployment and functions of the interaction module can be flexibly adjusted according to actual needs, and the system can be extended and customized according to different configurations and requirements of the vehicle.

[0044] Furthermore, the interaction module is used to receive a request input by the user, and generate a request instruction based on the request and send it to the main management module, or perform parameter configuration on each domain controller based on the request.

[0045] In some embodiments, through the visual interface of the interaction module, user inputs such as a fault viewing request or a configuration request can be received.

[0046] Among them, assuming that the user operates the interaction module to enter the fault viewing mode and clicks to view the corresponding domain controller, the interaction module will send a request to the main management module through a specific inter-domain network communication method.

[0047] The configuration requests include resource allocation, task scheduling, fault recovery, etc. for each domain controller or module.

[0048] In addition, the interaction module can generally support multiple input methods such as touch screen, voice, and gesture to meet the needs of different users, and also allows users to customize the interface layout and display content according to their preferences.

[0049] In the above technical solution, the user can directly input requests through the interaction module to perform real-time control and configuration of the vehicle without going through complex intermediate steps; and after receiving the request instruction, the main management module can immediately execute the corresponding diagnostic or control operation, improving the response speed of the system.

[0050] Furthermore, the main management module is also used to receive the request instruction sent by the interaction module, and based on the request instruction, return the corresponding status information to the interaction module for display.

[0051] In some embodiments, after the main management module receives the corresponding request from the interaction module, such as a fault viewing request, it will read the local database file, find the corresponding domain controller's preset information sorted by time, such as setting to display ten fault messages per page, and send these ten fault messages to the interaction module for display.

[0052] If the user operates the interaction module to select the next page, the interaction module will continue to send a request to the main management module. After receiving the request, the main management module will read the local database file and find the corresponding domain controller's fault messages sorted by time, such as the 11th to 20th fault messages, and send them to the interaction module.

[0053] In addition, the user can also view the health status of each domain controller in real time by operating the interaction module, such as information on CPU occupancy, MEM occupancy, storage occupancy, memory bandwidth occupancy, etc.; among them, after the main management module receives the load information (i.e., the status information) of each domain controller, it packs it in a certain format and sends it to the interaction module through a specific inter-domain network communication method. After receiving the load information of each domain controller, if it is in the health monitoring mode at this time, the interaction module will display this information in the form of a graphical interface.

[0054] For another example, the user selects a certain domain controller through the interface of the interaction module and clicks the button for fault recovery or resource allocation. The interaction module generates a corresponding request instruction and sends it to the main management module through a wireless link. After receiving the request, the main management module parses the operation and parameters to be executed. For a fault recovery request, the main management module calls the corresponding recovery program to attempt to repair the fault. If it receives that an irreparable fault has occurred in a certain domain controller, it can notify the power control module to perform a restart operation or other related operations on the corresponding domain controller. For a resource allocation request, the main management module adjusts the resource allocation policy of the domain controller to ensure that it obtains the required computing resources. After receiving the operation result, the interaction module displays the corresponding operation result on the visualization interface, notifies the user of the success or failure of the operation, and displays the corresponding information, etc.

[0055] In the above technical solution, the main management module can process the requests sent by the interaction module in real time and immediately return the corresponding status information, enabling the user to view the status information of the vehicle in real time, enhancing the real-time performance and transparency of the interaction.

[0056] Furthermore, the main management module is further configured to generate a diagnosis report and / or a diagnosis prompt according to the diagnosis result and send them to the interaction module for display.

[0057] In some embodiments, the diagnosis report can display the status and detailed information of each domain controller in the form of a table, list, etc.; the diagnosis prompt can be displayed in the form of a pop-up window or a notification to remind the user of the measures to be taken.

[0058] In the above technical solution, the main management module can generate a detailed diagnosis report based on the collected status information, such as including the specific location, cause, severity, and recommended repair measures of the problem, which helps the user quickly understand the health status of the vehicle; the diagnosis prompt can include operation guidance to tell the user how to perform preliminary troubleshooting or maintenance operations, enhancing the user-friendliness of the system; the diagnosis prompt can include operation guidance to tell the user how to perform preliminary troubleshooting or maintenance operations, enhancing the user-friendliness of the system.

[0059] Furthermore, the main management module is further configured to perform abnormal processing on the corresponding domain controller according to the abnormal information when the collected status information is abnormal information.

[0060] In some embodiments, the main management module can perform abnormal processing on the domain controller with an abnormality after receiving a fault handling request from the interaction module, or it can be automatically executed; regarding whether to manually confirm the abnormal processing or automatically execute the abnormal processing, it can be set by the user in the system, improving the flexibility of abnormal processing.

[0061] In the above technical solution, when the main management module detects that the status information is abnormal, it can immediately trigger the exception handling mechanism, quickly respond to the fault, reduce the impact time of the fault on the system, and the system can automatically process according to the exception information without manual intervention, improving the efficiency and speed of fault handling; the main management module can take corresponding self-healing measures according to the exception information, such as restarting the domain controller, adjusting parameters or isolating the faulty part to restore the normal operation of the system, enhancing the self-repair ability of the system.

[0062] In addition, through automated exception handling, the impact of faults on users is reduced, and the user experience and satisfaction are improved.

[0063] Furthermore, during the process of transmitting the status information, the slave management module is also used to simultaneously transmit the characteristic information of the corresponding domain controller to the main management module; wherein, the status information at least includes the health status and the running status.

[0064] In some embodiments, during the process of transmitting the status information, relevant characteristic information of the domain controller (such as the hardware configuration name, number, etc.) can also be added.

[0065] In the above technical solution, the status information includes the health status and the running status, and the characteristic information may include the configuration of the domain controller. Through multi-dimensional data collection, the main management module can more comprehensively understand the status of each domain controller. Combining the status information and the characteristic information, the system can achieve real-time monitoring of the domain controller, timely detect abnormal situations, and enhance the early warning ability of the system.

[0066] Based on the same concept, please refer to Figure 2 This application also provides a vehicle diagnosis method. The vehicle diagnosis method is applied to the vehicle diagnosis system and includes:

[0067] The main management module collects the status information of the corresponding domain controller collected by each slave management module based on the wireless link, and performs diagnostic analysis on each domain controller based on the status information to obtain a diagnostic result; wherein, it also includes:

[0068] The slave management module detects the wireless link in real time, and when the wireless link is detected to be abnormal, stores the collected status information, and transmits the stored status information to the main management module after the wireless link returns to normal.

[0069] In some embodiments, the slave management modules inside each domain controller regularly collect or acquire the load information of the domain controller, including CPU occupancy, MEM occupancy, storage occupancy, memory bandwidth occupancy, etc., plus the relevant characteristic information of the domain controller (such as number and name, etc.), and send it to the master management module through a specific inter-domain network communication method; the main pipeline module receives the load information of each domain controller, packs it in a certain format, and sends it to the interaction module for display through a specific inter-domain network communication method.

[0070] The slave management module also regularly collects or acquires the fault information of the domain controller, including fault description, fault type, fault time, fault status and other information, and then adds the relevant information of the domain controller (name and number, etc.) and sends it to the master management module through a specific inter-domain network communication method; if the slave management module detects that the Ethernet communication link with the master management module is disconnected, it saves the fault information to the local database file and waits until the communication link is restored and then sends the fault information in the local database file to the master management module again.

[0071] After receiving the fault information of each domain controller, the master management module saves it to the local database file. At the same time, the master management module can perform relevant operations on each domain controller according to the corresponding fault information. For example, when it receives that a certain domain controller has an irrecoverable fault, it can notify the power control module to perform a restart operation on the corresponding domain controller.

[0072] Among them, the master management module analyzes the collected health status and operating conditions, and according to preset rules and algorithms, judges the status of each domain controller or module, such as normal, abnormal, faulty, etc., and generates corresponding reports and prompts according to the analysis results and sends them to the display module; it should be noted that the above load information and fault information are collectively referred to as status information.

[0073] In the above technical solution, when the wireless link is abnormal, the slave management module can store the collected status information, avoiding data loss and ensuring data integrity. After the wireless link returns to normal, the slave management module can transmit the stored status information to the master management module, ensuring data continuity and consistency; it can be seen that the system can continue to collect and store data when the wireless link is abnormal, enhancing the system's fault tolerance ability and improving the system's reliability. And the system can automatically resume data transmission after the wireless link returns to normal, reducing the need for manual intervention and improving the system's stability; at the same time, each module focuses on its specific task, can effectively collect the diagnostic information of the domain controller and its modules, improving the information processing efficiency and enhancing the overall stability of the system.
