[0043] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0044] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0045] The main solution of the embodiment of the present application is: based on a preset functional diagnosis sequence, a controller execution diagnostic instruction is sent to the vehicle end, and the vehicle end sends the controller execution diagnostic instruction to the corresponding controller, and the controller performs diagnosis according to the controller execution diagnostic instruction to obtain a controller diagnosis result, and the controller execution diagnostic instruction includes at least one or more of a diagnostic function execution instruction and a learning routine instruction; and the controller diagnosis result returned by the vehicle end is received, and the controller diagnostic function result includes at least one or more of a diagnostic function execution result and a learning result.

[0046] As cars are now electronic, the application of automotive electronic technology will make cars more intelligent, and the use of vehicles is becoming more and more popular. ECU (Electronic Control Unit), also known as the "driving computer" of the car, is used to control the driving state of the car and realize its various functions. It mainly uses various sensors and bus data collection and exchange to judge the vehicle state and the driver's intention and control the car through the actuator. Currently, multiple ECUs are installed on vehicles. New vehicles leaving the factory need to perform function configuration, function learning, and related parameter writing of each ECU system before they can be shipped out for customer use to ensure that all functions of the vehicle are normal.

[0047] The existing method of vehicle diagnosis is to execute all functions of the ECU controller in sequence, and execute the function configuration of the next ECU after the current ECU is completed, until all controllers are completed. For example, if some body controllers need a certain time (10s-60s) to complete the sunroof and window learning execution functions, the diagnostic equipment will always wait for the results of the body controller execution function, resulting in a long vehicle diagnosis time, failure to meet the production line's production rhythm, and low production efficiency.

[0048] The present application diagnoses the controller on the vehicle side by sending a controller execution diagnostic instruction to the vehicle side through a functional diagnostic sequence, thereby realizing controller function diagnosis based on diagnostic sequence and instruction control, solving the problem of low efficiency of vehicle controller function diagnosis in the prior art, and improving the diagnostic efficiency of the vehicle controller function.

[0049] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a vehicle-mounted device, etc. that can realize the above functions. The following takes the vehicle-mounted device as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the present application embodiment provides a controller diagnosis method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the controller diagnosis method of the present application.

[0051] In this embodiment, the controller diagnosis method is applied to the diagnosis end, including steps S10 to S20:

[0052] Step S10, sending a controller execution diagnosis instruction to the vehicle end based on a preset function diagnosis sequence, the vehicle end sending the controller execution diagnosis instruction to the corresponding controller, the controller performing diagnosis according to the controller execution diagnosis instruction to obtain a controller diagnosis result, the controller execution diagnosis instruction at least includes one or more of a diagnosis function execution instruction and a learning routine instruction;

[0053] It should be noted that the functional diagnostic sequence refers to the controller diagnostic sequence arranged in a certain order to ensure that it is carried out step by step to avoid diagnostic conflicts or interference. The vehicle end refers to the diagnostic system or central control unit on the vehicle, which is responsible for receiving instructions from the diagnostic end and forwarding them to the corresponding controller. The controller executes diagnostic instructions pointing to specific instructions issued by the controller, including executing diagnostic functions and running learning routines. Diagnostic function execution instructions refer to instructions that allow the controller to detect and verify specific functions. Learning routine instructions refer to instructions that allow the controller to perform self-learning or calibration processes to adapt to new situations or optimize performance. The controller diagnostic results refer to the feedback information returned by the controller on the vehicle end, which may include information such as the status, error information or performance data of the controller.

[0054] It can be understood that controller diagnostic instructions are sent from the diagnostic end to the vehicle end so that the vehicle end conveys these instructions to specific controllers. Different controllers will perform their respective diagnostic tasks after receiving different controller diagnostic instructions, thereby ensuring that all controllers are diagnosed in accordance with the preset functional diagnostic order to obtain diagnostic results.

[0055] Step S20, receiving the controller diagnosis result returned by the vehicle end, wherein the controller diagnosis function result at least includes one or more of a diagnosis function execution result and a learning result.

[0056] It should be noted that the diagnostic functions performed by the controller may include the diagnosis of typical faults and fault simulation tests. Typical faults may include power supply faults, input faults (sensors, switches), output faults (relays, motors) and network faults. Fault simulation tests verify the self-diagnosis function of the on-board diagnostic system by simulating faults, including fault confirmation conditions, recovery conditions, levels and alarm methods. The controller diagnostic results may include the results of the execution of diagnostic functions and the learning results, specifically in the form of fault information, data streams and other forms of information.

[0057] It can be understood that the diagnostic end receives the controller diagnostic results returned from the vehicle end to analyze whether the status and function of the controller are normal. By reasonably arranging the diagnostic sequence and feedback mechanism, it can ensure that all controllers are accurately diagnosed and the diagnostic results can be obtained and processed in time, so as to quickly discover and solve problems.

[0058] In a feasible implementation manner, before the step of sending a controller to execute a diagnostic instruction to the vehicle end based on a preset function diagnosis sequence, the step further includes:

[0059] Step S101, obtaining the VIN code of the vehicle end and verifying the VIN code;

[0060] It should be noted that the VIN code refers to the vehicle identification code used to identify and verify the identity of the vehicle. It is a code that uniquely identifies each vehicle.

[0061] Understandably, the latest regulations require that for vehicles equipped with electronic control units, at least one ECU should store the vehicle identification number in a tamper-proof manner, written in accordance with the developed program. Therefore, it is necessary to verify the correctness and validity of the VIN code when the vehicle controller unit is connected or replaced to ensure that the VIN code complies with the predetermined format and rules to prevent illegal or erroneous data.

[0062] Step S102, if the VIN code verification passes, then execute the step: send a controller execution diagnosis instruction to the vehicle end based on a preset function diagnosis sequence.

[0063] It can be understood that after the VIN code is successfully verified, a controller diagnostic instruction is sent to the vehicle end according to the preset functional diagnostic sequence, ensuring that the VIN code on the vehicle end is verified before a comprehensive and systematic diagnosis of the vehicle is performed in a predetermined sequence, and that the ECU controller has a confirmed VIN code.

[0064] In this implementation, by obtaining and verifying the VIN code, it is ensured that the diagnosis is only performed on legal vehicles, thereby avoiding invalid diagnosis or safety problems caused by the wrong vehicle, and sending controller diagnostic instructions to the vehicle end according to the preset functional diagnosis sequence, ensuring that each controller can perform functional verification or fault detection in the set order, thereby achieving faster and more accurate troubleshooting and maintenance in actual applications.

[0065] In a feasible implementation manner, the vehicle end includes a plurality of controllers, and before the step of sending the controller execution diagnosis instruction to the vehicle end based on the preset function diagnosis sequence, the step further includes:

[0066] Step S103, obtaining the vehicle model information of the vehicle end and the functional configuration of the plurality of controllers;

[0067] It should be noted that the vehicle model information may include the vehicle manufacturer, model, year, etc., which is used to determine the basic characteristics and configuration of the vehicle and determine the diagnostic plan suitable for the vehicle model. The functional configuration of the controller refers to the functions and characteristics of each controller, such as the MCU (Motor Control Unit) motor controller module, the VCU (Motor Control Unit) motor controller module, etc., which is used to ensure that the function of each controller is correctly identified for effective diagnosis.

[0068] It is understandable that the vehicle model information and the functional configuration of the controller are collected to understand the specific situation of the vehicle and the functions of each controller.

[0069] Step S104, determining the diagnosis priorities of the plurality of controllers according to the vehicle type information and the functional configurations of the plurality of controllers;

[0070] It is understandable that the priority of different controllers in diagnosis is determined based on the acquired vehicle model information and controller function configuration, where the priority determination rules may be based on factors such as the importance of the controller, the frequency of faults, and the impact on vehicle performance, thereby giving priority to diagnosing critical controllers or controllers that affect the overall diagnostic efficiency, ensuring that the most important controller problems are dealt with in a timely manner.

[0071] Step S105: generating a functional diagnosis sequence according to the diagnosis priority.

[0072] It can be understood that an ordered functional diagnosis sequence is generated according to the diagnostic priority of the controller, and the controller is arranged at an appropriate position in the diagnostic process according to the priority, ensuring that the diagnosis is performed according to the predetermined priority and sequence, thereby improving the diagnostic efficiency and accuracy.

[0073] In this implementation, firstly, by obtaining detailed vehicle model and controller function configuration information, accurate understanding of each vehicle model and controller is ensured to make the diagnosis plan more targeted; the diagnosis priority is determined based on the controller's function and fault history record to ensure that the most critical controllers or controllers with special needs are checked first and resource allocation is optimized; finally, a reasonable diagnosis sequence is generated according to the priority, which can be systematically diagnosed to avoid omissions and duplications, further improving the overall diagnostic efficiency and accuracy, thereby improving the systematicness and accuracy of the diagnostic process, making vehicle troubleshooting more efficient and adaptable.

[0074] In a feasible implementation manner, the step of determining the diagnostic priorities of the plurality of controllers according to the vehicle type information and the functional configurations of the plurality of controllers comprises:

[0075] Step S1041, acquiring learning waiting time of the plurality of controllers according to the vehicle type information and the functional configurations of the plurality of controllers;

[0076] It is understandable that individual controllers require a certain amount of time to go through the diagnostic learning process and complete the self-adjustment or adaptation process before diagnosis. Therefore, it is necessary to determine the learning waiting time of each controller of the vehicle before diagnosis to determine which controllers need to be checked and processed first.

[0077] Step S1042: Prioritize the controllers based on their learning waiting times to determine their diagnosis priorities.

[0078] It is understandable that the controllers are sorted according to the length of their learning waiting time. For example, controllers with long waiting times will be given higher priorities, ensuring that during the diagnosis process, those controllers with long learning waiting times are given priority. This can reduce the impact of the diagnostic learning of these controllers on the diagnosis of other controllers and improve the effectiveness and accuracy of the overall diagnosis.

[0079] In this implementation, the learning waiting time of each controller on the vehicle side is accurately obtained, and the controllers are prioritized according to these times to ensure that those controllers with longer learning waiting times are given priority during the diagnosis process, and that diagnosis is performed after the controllers have completed self-adjustment, thereby improving the accuracy and reliability of the diagnosis results. By dynamically adjusting the priority, it is possible to adapt to the actual working state of the controller, further optimize the diagnosis process, and ultimately improve the efficiency and effectiveness of vehicle controller diagnosis.

[0080] In a feasible implementation manner, the controller includes at least one or more of a controller to be learned and a controller to be diagnosed, the learning routine instruction includes at least one or more of a start learning routine instruction and a learning result query instruction, and the method further includes steps A1 to A4:

[0081] Step A1, sending a start learning routine instruction for the controller to be learned to the vehicle end, the vehicle end sending the start learning routine instruction to the controller to be learned, and the controller to be learned performing learning diagnosis according to the learning routine instruction;

[0082] It can be understood that a start learning routine instruction is sent to the controller on the vehicle side that requires diagnostic learning. After receiving the start learning routine instruction, the controller starts its learning process. During the learning process, the controller will adjust its internal parameters so that it can adapt to the operating status of the vehicle and ensure that the controller to be learned enters the learning mode, so that it can complete the necessary adjustments in the subsequent operations to improve the overall performance of the system.

[0083] Step A2, sending a diagnostic function instruction for the controller to be diagnosed to the vehicle end, the vehicle end sending the diagnostic function execution instruction to the controller to be diagnosed, the controller to be diagnosed performs the diagnostic function according to the diagnostic function execution instruction, obtains the diagnostic function execution result and returns it to the diagnostic end;

[0084] It can be understood that a diagnostic function execution instruction is sent to the controller that needs to be diagnosed on the vehicle side. After receiving the diagnostic function execution instruction, the diagnostic controller executes its diagnostic function, detects its working status and returns the result to ensure that the status of the controller to be diagnosed is checked to obtain detailed information on its working condition and potential problems.

[0085] Step A3, monitoring the learning status of the controller to be learned in the vehicle end;

[0086] It is understandable that the learning progress and status of the controller to be learned are monitored in real time to ensure that its learning process proceeds as expected, to determine whether the controller has completed the learning process, and to facilitate subsequent diagnostic operations.

[0087] Step A4, if the learning status of the controller to be learned is completed, a learning result query instruction for the controller to be learned is sent to the vehicle end, and the vehicle end queries the learning result of the controller to be learned according to the learning result query instruction and returns it to the diagnosis end.

[0088] It is understandable that when it is monitored that the learning process of the controller to be learned has been completed, the specific results of the learning are obtained by querying the learning result instruction, and the results of the controller in the learning process are obtained to evaluate its learning effect.

[0089] In this embodiment, efficient coordination processing is performed during the learning and diagnosis process of the controller to be learned and the controller to be diagnosed, ensuring that each controller can execute instructions efficiently, thereby improving the overall performance and reliability of the vehicle, optimizing the learning and diagnosis process of the controller, improving the diagnostic efficiency of the vehicle controller, and realizing intelligent management and fault prevention of the vehicle system.

[0090] This embodiment provides a controller diagnosis method, which diagnoses the controller on the vehicle side by sending a controller execution diagnosis instruction to the vehicle side through a functional diagnosis sequence, thereby realizing controller function diagnosis based on diagnosis sequence and instruction control, solving the problem of low efficiency of vehicle controller function diagnosis in the prior art, and improving the diagnostic efficiency of vehicle controller functions.

[0091] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can refer to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the controller diagnosis method of the present application.

[0092] In this embodiment, the controller diagnosis method is applied to the vehicle side, and further includes steps S30 to S50:

[0093] Step S30, receiving a controller execution diagnosis instruction sent by the diagnosis terminal based on a preset function diagnosis sequence, wherein the controller execution diagnosis instruction includes at least one or more of a diagnosis function execution instruction and a learning routine instruction;

[0094] It can be understood that the vehicle end receives the controller execution diagnostic instructions sent from the diagnostic end in a functional diagnostic sequence. The instructions may include commands for the controller to execute diagnostic functions or start a learning routine, ensuring that the vehicle end can correctly receive and understand the instructions from the diagnostic end, thereby performing corresponding controller operations.

[0095] Step S40, sending the controller execution diagnosis instruction to the corresponding controller, and the controller performs diagnosis according to the controller execution diagnosis instruction to obtain a controller diagnosis result, wherein the controller diagnosis function result at least includes one or more of a diagnosis function execution result and a learning result;

[0096] It can be understood that the controller execution diagnostic instructions received from the diagnostic end are passed to the relevant controllers in the vehicle to enable them to perform corresponding diagnostic tasks, ensuring that the controllers can operate according to the diagnostic instructions, thereby generating effective diagnostic results.

[0097] Step S50, returning the controller diagnosis result to the diagnosis terminal.

[0098] It is understandable that the vehicle end sends the diagnostic results of the controller back to the diagnostic end for further analysis and processing, so that the diagnostic end can obtain the diagnostic results of the controller for subsequent evaluation or processing.

[0099] In this embodiment, the vehicle-side receiving diagnostic end executes diagnostic instructions sent by the diagnostic end in a functional diagnostic sequence to diagnose the controller on the vehicle-side, thereby realizing controller function diagnosis based on diagnostic sequence and instruction control, solving the problem of low efficiency of vehicle controller function diagnosis in the prior art, and improving the diagnostic efficiency of vehicle controller functions.

[0100] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the first and second embodiments mentioned above can be referred to the above introduction and will not be repeated later.

[0101] For example, taking the VCI (Vehicle Communication Interface) vehicle diagnostic instrument as an example, the VCI diagnostic instrument is a tool used for vehicle diagnosis and maintenance. Its main function is to serve as a bridge between the vehicle's electronic system and the diagnostic equipment, and is used to connect the vehicle's diagnostic port with a computer or other diagnostic tools. The VCI diagnostic instrument communicates with the vehicle's ECU controller by connecting to the vehicle's OBD (On-Board Diagnostics) interface to perform system inspection, fault diagnosis and data reading.

[0102] like Figure 3 As shown, Figure 3 A flowchart of the third embodiment of the controller diagnostic method of the present application is provided. In this embodiment, the controller diagnostic method is applied to a VCI vehicle diagnostic instrument and may include the following steps:

[0103] 1. Configure each ECU diagnostic function (write configuration, write VIN, etc.) according to the vehicle model and system.

[0104] 2. Configure the order in which each system executes functions. The ECU diagnostic function operation with time limit has the highest priority (i.e., it is diagnosed first).

[0105] 3. Scan the VIN and verify. After the verification is qualified, VCI will perform relevant diagnostic configuration functions on each configured ECU in sequence.

[0106] 4. VCI has a time limit (10s-60s) to complete the diagnosis of ECU controllers. VCI first only sends the instruction to enter the learning routine, and then queries and reads the learning result status after all ECUs are diagnosed.

[0107] 5. If the BCM controller (Body Control Module) needs to perform the learning diagnosis function of the sunroof and windows, the ECU needs to learn the waiting time.

[0108] 6. VCI executes ECU according to configuration. If the vehicle model has been configured with BCM, it needs to execute the learning diagnosis function of sunroof and windows:

[0109] 1) Take the BCM executing the window learning diagnosis function as an example, and the others are similar.

[0110] 2) VCI sends a window start learning routine command to the BCM controller, and the BCM controller receives and replies with a positive response.

[0111] 3) After the VCI receives the positive response feedback of the window start learning routine, it records and marks the BCM to execute the window learning function status (WindowStart=1) and the negative response status (WindowStart=0).

[0112] 7. VCI sequentially executes the diagnostic functions controlled by other ECUs, and the ECUs feed back their diagnostic execution and display results (pass or fail).

[0113] 8. After VCI executes the diagnosis-related functions of the system configured for this vehicle model, it intelligently determines the window learning status (WindowStart) value.

[0114] 9. If WindowStart = 1, the window learning result query needs to be executed, and the VCI sends the corresponding instructions to the BCM controller to read the window learning result and display the learning result (success or failure).

[0115] 10. If WindowStart = 0, there is no need to execute the window learning result query, and the result of the vehicle diagnosis is returned directly.

[0116] 11. Replace vehicle diagnosis and follow steps 3-10 in order.

[0117] Among them, during the VCI diagnosis process of the vehicle, if there is a time limit for the operation of the ECU controller, VCI only sends the ECU controller to enter the learning routine instruction, and does not wait for the query of the learning result status. After VCI obtains the positive response of the ECU to enter the learning routine instruction, it directly executes the next ECU controller for diagnosis. After all controllers are diagnosed, it reads the controller ECU learning result status and displays the corresponding controller ECU learning result status, which can effectively shorten the vehicle diagnosis time, improve the diagnosis efficiency and user experience, and thus improve production efficiency.

[0118] In this embodiment, the controller on the vehicle side is diagnosed by sending a controller execution diagnostic instruction to the vehicle side in a functional diagnostic sequence, thereby realizing controller function diagnosis based on diagnostic sequence and instruction control, solving the problem of low efficiency of vehicle controller function diagnosis in the prior art, and improving the diagnostic efficiency of vehicle controller functions.

[0119] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the controller diagnostic method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
