[0055] 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.

[0056] 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.

[0057] The main solutions of the embodiments of this application are:

[0058] Receive vehicle diagnostic instructions;

[0059] Based on a pre-generated interaction mode configuration table, according to the vehicle diagnostic instruction, determining a corresponding interaction mode as a target interaction mode;

[0060] Based on the target interaction mode and according to the vehicle diagnostic instruction, the vehicle is diagnosed to generate a vehicle diagnostic result.

[0061] The existing technology requires data transmission and interaction when diagnosing a vehicle. There are many modes of data interaction, such as send-one-receive, send-multiple-receive, send-multiple-receive, etc. Each mode has its own advantages and disadvantages. However, there are many different diagnostic scenarios. Using a single transmission mode is inefficient and in some diagnostic scenarios it will affect the efficiency and success rate of the diagnostic function.

[0062] The present application provides a solution, based on the interaction mode configuration table, according to the vehicle diagnosis instruction, automatically selects the corresponding interaction mode as the target interaction mode. According to the interaction mode configuration table, the appropriate interaction mode is automatically selected as the target interaction mode, which solves the technical problems of the existing vehicle diagnosis method with fixed data transmission mode and poor data transmission efficiency, and improves the data transmission efficiency and the success rate of the diagnosis function execution.

[0063] It should be noted that the execution subject of this embodiment may 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 capable of realizing the above functions, a vehicle diagnostic system, etc. The following takes the vehicle diagnostic system as an example to illustrate this embodiment and the following embodiments.

[0064] Based on this, the embodiment of the present application provides a vehicle diagnosis method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle diagnostic method of the present application.

[0065] In this embodiment, the vehicle diagnosis method includes steps S10 to S30:

[0066] Step S10, receiving a vehicle diagnosis instruction;

[0067] It should be noted that the vehicle diagnostic instruction is a command issued by the user or the system, indicating the diagnostic operation that needs to be performed.

[0068] Step S20, based on the pre-generated interaction mode configuration table and according to the vehicle diagnostic instruction, determining the corresponding interaction mode as the target interaction mode;

[0069] The vehicle diagnostic system queries the interaction mode configuration table according to the characteristics of the vehicle diagnostic instructions (such as reading fault codes, real-time data, etc.) and matches the corresponding interaction mode as the target interaction mode.

[0070] It should be noted that the interaction mode configuration table is used to record the operation processes and modes corresponding to different instructions to ensure that the system can select the appropriate response method.

[0071] In a feasible implementation, step S20 may include steps S201 to S202:

[0072] Step S201, performing diagnostic scenario analysis on the diagnostic function data in the vehicle diagnostic instruction to obtain diagnostic scenario data;

[0073] Step S202: Match the diagnostic scenario data with the interaction mode configuration table to determine the corresponding interaction mode as the target interaction mode.

[0074] The vehicle diagnostic system performs diagnostic scenario analysis on the diagnostic function data in the vehicle diagnostic instructions to obtain diagnostic scenario data, and then compares the diagnostic scenario data with the interaction mode configuration table based on the key features in the diagnostic scenario data to determine one or more corresponding interaction modes as the target interaction mode, ensuring that the selected mode can effectively meet user needs and system functional requirements.

[0075] In this embodiment, by matching the diagnostic scenario data with the interaction mode configuration table, the interaction mode that best suits the current scenario can be accurately identified. The system can provide corresponding operation guidance or feedback based on different diagnostic scenarios, optimize the user experience, and make it more efficient when handling faults.

[0076] In another feasible implementation manner, before step S20, steps S401 to S405 may also be included:

[0077] Step S401, obtaining initial diagnostic function data;

[0078] Step S402, classifying the initial diagnostic function data based on a preset scene classification rule to obtain classified diagnostic function data;

[0079] Step S403, associating the classified diagnostic function data with the preset initial diagnostic scenario data to generate a function scenario association relationship;

[0080] Step S404, associating the diagnostic scenario data with a preset initial interaction mode to generate a scenario mode association relationship;

[0081] Step S405, generating the interaction mode configuration table according to the initial diagnosis scenario data, the initial interaction mode, the function scenario association relationship and the scenario mode association relationship.

[0082] The vehicle diagnostic system obtains initial diagnostic function data, and then classifies the initial diagnostic function data based on preset scenario classification rules, organizes the data into different scenarios, obtains classified diagnostic function data, and then associates the classified diagnostic function data with the preset initial diagnostic scenario data to generate a function-scenario association relationship, and then associates the diagnostic scenario data with the preset initial interaction mode to generate a scene-mode association relationship, and finally generates an interaction mode configuration table based on the initial diagnostic scenario data, the initial interaction mode, the function-scenario association relationship and the scene-mode association relationship.

[0083] In this implementation, through systematic data classification and association, the misjudgment in traditional methods is reduced and the accuracy of diagnosis is enhanced. By dynamically generating an interactive mode configuration table, the system can flexibly adapt to different diagnostic scenarios and meet diverse needs. Through efficient classification and association, the system can respond to user requests faster, thereby improving overall work efficiency and shortening fault handling time. As a result, the intelligence and accuracy of vehicle diagnosis are improved, the user's interactive experience is optimized, and many technical defects in traditional methods are solved.

[0084] Step S30, based on the target interaction mode and according to the vehicle diagnosis instruction, diagnose the vehicle and generate a vehicle diagnosis result.

[0085] The vehicle diagnostic system performs specific diagnostic operations on the vehicle and generates diagnostic results based on the determined target interaction mode and vehicle diagnostic instructions.

[0086] This embodiment provides a vehicle diagnosis method, which automatically selects a corresponding interaction mode as a target interaction mode based on an interaction mode configuration table and according to a vehicle diagnosis instruction. According to the interaction mode configuration table, a suitable interaction mode is automatically selected as the target interaction mode, which solves the technical problems of the existing vehicle diagnosis method in which the data transmission mode is fixed and the data transmission efficiency is poor, and improves the data transmission efficiency and the success rate of the execution of the diagnosis function.

[0087] 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 above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , step S30 includes steps S301 to S303:

[0088] Step S301, screening a plurality of vehicle electronic control units in the vehicle according to the name of the electronic control unit to be diagnosed in the vehicle diagnosis instruction to obtain a target electronic control unit;

[0089] Step S302, based on the target interaction mode, interacting with the target electronic control unit according to a plurality of diagnostic function instructions to be executed in the vehicle diagnostic instructions, to obtain reply data of the diagnostic function instructions to be executed;

[0090] Step S303, performing diagnostic analysis according to the reply data of the diagnostic function instruction to be executed to generate the vehicle diagnostic result.

[0091] The vehicle diagnostic system selects a target electronic control unit corresponding to the name of the electronic control unit to be diagnosed from multiple electronic control units in the vehicle according to the name of the electronic control unit to be diagnosed in the vehicle diagnostic instruction, and then based on the target interaction mode, interacts with the target electronic control unit according to several diagnostic function instructions to be executed in the vehicle diagnostic instruction, executes the diagnostic function instructions to be executed and obtains reply data, obtains reply data of the diagnostic function instructions to be executed, and finally performs diagnostic analysis based on the reply data of the diagnostic function instructions to be executed to generate a vehicle diagnostic result.

[0092] In a feasible implementation manner, the target interaction mode is a multi-send and multi-receive mode, the target electronic control unit includes a plurality of second target electronic control units, the to-be-executed diagnostic function instruction reply data is the second to-be-executed diagnostic function instruction reply data, and step S302 may include steps S30221 to S30223:

[0093] Step S30221, based on the multi-transmit and multi-receive mode, each of the to-be-executed diagnostic function instructions is sent to the corresponding second target electronic control unit;

[0094] Step S30222, receiving the second function instruction reply data sent by each second target electronic control unit within a preset waiting time, and obtaining a plurality of the second function instruction reply data;

[0095] Step S30223, obtaining the second to-be-executed diagnostic function instruction response data according to a plurality of the second function instruction response data.

[0096] Based on the send-multiple-receive mode, the vehicle diagnostic system sends each diagnostic function instruction to be executed to the corresponding second target electronic control unit respectively. Within the preset waiting time, the system receives the second function instruction reply data from each second target electronic control unit, obtains several second function instruction reply data, and finally integrates the received multiple second function instruction reply data to generate unified second diagnostic function instruction reply data to be executed.

[0097] It should be noted that the send-multiple-receive mode is a communication mode that allows multiple requests to be sent and multiple responses to be received at the same time, thereby enhancing parallel processing capabilities.

[0098] For example, the vehicle ECU (Electronic Control Unit) is an electronic control unit, also known as a computer control module, a driving computer, a car computer, etc. It is one of the core electronic components of modern cars. The role and function of ECU are very wide. The following is a detailed analysis of vehicle ECU.

[0099] The main functions of ECU:

[0100] Data collection and processing: ECU can collect data from various sensors in real time, such as engine speed, vehicle speed, air flow, water temperature, etc., and process and analyze these data.

[0101] Control actuators: Based on the processed data, the ECU will send control signals to each actuator (such as injector, ignition coil, throttle, etc.) to achieve the predetermined control function.

[0102] Fault diagnosis and protection: ECU has fault self-diagnosis function, which can detect and record the fault information of each vehicle system, and take protective measures when necessary to maintain the basic operation of the vehicle.

[0103] Adaptive learning: The ECU also has a learning function that can record and analyze the driver's driving habits to optimize the vehicle's control strategy and improve driving comfort and fuel economy.

[0104] In this embodiment, the multi-send and multi-receive mode allows the system to interact with multiple second target ECUs at the same time, thereby significantly improving the concurrent processing capability of the diagnosis. This means that the diagnosis of multiple ECUs can be performed simultaneously, greatly shortening the overall diagnosis time, receiving feedback data within the preset waiting time, ensuring that the diagnosis results of each ECU are obtained within the specified time, achieving rapid response, and improving the user experience. Based on the received multiple second function instruction reply data, the final second diagnostic function instruction reply data to be executed is obtained through comprehensive analysis, making the diagnosis results more comprehensive and accurate. This mode can flexibly adapt to different types of ECUs, has good scalability, and can support the rapid access of new models or new ECUs. As a result, not only the efficiency and accuracy of vehicle diagnosis are improved, but also multiple technical defects in the traditional diagnosis process are effectively solved, such as long diagnosis time, inaccurate data, and poor user experience.

[0105] In this embodiment, by accurately screening the electronic control unit, it is ensured that only relevant units are subsequently interacted with, which improves the pertinence of the diagnosis. By using the target interaction mode, efficient communication with the electronic control unit can be carried out, and the feedback data of the required diagnostic function instructions can be quickly obtained. As a result, not only the efficiency and accuracy of vehicle diagnosis are optimized, but also multiple technical defects in traditional diagnostic methods are effectively solved, making the entire process more intelligent.

[0106] Based on the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above-mentioned second embodiment can refer to the above introduction, and will not be repeated in the following. Figure 3 , the target interaction mode is a send-multiple-receive-one mode, the target electronic control unit is a first target electronic control unit, the to-be-executed diagnostic function instruction reply data is a first to-be-executed diagnostic function instruction reply data, and step S302 further includes steps S30211 to S30216:

[0107] Step S30211, based on the send-multiple-receive-one mode, divide a plurality of diagnostic function instructions to be executed by frame number to obtain a plurality of first diagnostic function instruction sets to be executed;

[0108] Step S30212, sequentially selecting each of the plurality of the first to-be-executed diagnostic function instruction sets as a first to-be-sent instruction set;

[0109] Step S30213, first instruction sending step: sending the first to-be-sent instruction set to the first target electronic control unit;

[0110] Step S30214, first data receiving step: receiving first function instruction reply data sent by the first target electronic control unit;

[0111] Step S30215, based on the send-multiple-receive-one mode, repeatedly executing the first instruction sending step and the first data receiving step until all of the first to-be-sent instruction sets are sent to the first target electronic control unit, and a plurality of the first function instruction reply data are obtained;

[0112] Step S30216: Obtain the first to-be-executed diagnostic function instruction response data according to a plurality of the first function instruction response data.

[0113] Based on the send-many-receive-one mode, the vehicle diagnostic system divides a number of diagnostic function instructions to be executed by frame number to obtain a number of first diagnostic function instruction sets to be executed, and then selects each of the first diagnostic function instruction sets to be executed in turn as a first instruction set to be sent, and then sends the first instruction set to be sent to a first target electronic control unit, and receives first function instruction reply data sent by the first target electronic control unit. Based on the send-many-receive-one mode, the first instruction sending step and the first data receiving step are repeatedly executed until all of the first instruction sets to be sent are sent to the first target electronic control unit, and a number of first function instruction reply data are obtained.

[0114] It should be noted that the send-multiple-receive-one mode allows the system to send multiple commands at the same time, but only needs to receive feedback once. This method can significantly improve communication efficiency, especially when a large number of commands need to be executed.

[0115] In a feasible implementation manner, the target interaction mode is a send-receive-receive mode, the target electronic control unit is a third target electronic control unit, the to-be-executed diagnostic function instruction reply data is a third to-be-executed diagnostic function instruction reply data, and step S302 further includes steps S30231 to S30235:

[0116] Step S30231, based on the send-one-receive-one mode, sequentially selecting each of the plurality of diagnostic function instructions to be executed as a first target function instruction;

[0117] Step S30232, second instruction sending step: sending the first target function instruction to the third target electronic control unit;

[0118] Step S30233, second data receiving step: receiving third function instruction reply data sent by the third target electronic control unit;

[0119] Step S30234, based on the send-one-receive-one mode, repeatedly executing the second instruction sending step and the second data receiving step until a plurality of the first target function instructions are all sent to the third target electronic control unit, and a plurality of the third function instruction reply data are obtained;

[0120] Step S30235, obtaining the third diagnostic function instruction response data to be executed according to a plurality of the third function instruction response data.

[0121] Based on the send-one-receive-one mode, the vehicle diagnostic system selects each of the several diagnostic function instructions to be executed as the first target function instruction in turn, then sends the first target function instruction to the third target electronic control unit, and receives the third function instruction reply data sent by the third target electronic control unit. Based on the send-one-receive-one mode, the second instruction sending step and the second data receiving step are repeated until the several first target function instructions are all sent to the third target electronic control unit, and several third function instruction reply data are obtained. Finally, the several third function instruction reply data are summarized and analyzed to obtain the third diagnostic function instruction reply data to be executed.

[0122] It should be noted that the send-receive mode is a communication mode that emphasizes receiving a feedback after each instruction is sent to ensure the execution of the instruction and the accuracy of the feedback.

[0123] In this embodiment, by selecting and sending the diagnostic function instructions to be executed in sequence, the system can process each instruction in an orderly manner, ensure that the response of each instruction is received and recorded in time, avoid conflicts or confusion between instructions, and immediately receive and confirm feedback data after each instruction is sent, which helps to accurately record the status of each instruction and reduce the possibility of misoperation, thereby improving the accuracy of overall feedback. The send-receive mode simplifies the diagnostic steps, makes the operation more intuitive, reduces the learning curve of technicians, and improves diagnostic efficiency. Since feedback is received immediately after each instruction is sent, the system can achieve faster real-time monitoring and response, and timely discover and handle potential faults. Therefore, through orderly instruction sending and feedback reception, not only the system's operating efficiency and data processing accuracy are improved, but also many technical defects in traditional diagnostic modes are effectively solved.

[0124] For example, the commonly used interaction modes currently include: send one receive one mode, which means sending a diagnostic command and waiting for the ECU's reply before sending the next diagnostic command. It is generally more suitable for continuous diagnostic operations on the same ECU, such as reading the fault code first and then clearing the fault code; send multiple receive one mode, which is mainly suitable for sending a large amount of data to an ECU. For example, when flashing the ECU, you may need to send several thousand bytes at a time. If each frame sent needs to wait for the ECU to reply, it will be too slow, so you can send multiple frames of commands to receive a reply from the ECU, reducing the time for receiving multiple ECU replies; send multiple receive multiple mode, which is generally used to request data from multiple ECUs at the same time, such as sending a read fault code command to all ECUs of the vehicle to read the fault code data in each ECU. You can send multiple read fault code commands to each ECU at the same time, and then receive multiple fault code data from multiple ECU replies.

[0125] Different diagnostic scenarios can be configured with different interaction modes to generate an interaction mode configuration table. In the configuration table, a specific diagnostic scenario is configured with a specified interaction mode, such as configuring the flashing function of each ECU to send multiple and receive one mode, configuring the ECU scanning and reading of fault codes of the entire vehicle to send multiple and receive multiple modes, and the others default to send one and receive one mode.

[0126] 1. When diagnosing a vehicle through diagnostic equipment, query the interactive mode configuration table to determine which interactive mode to use based on the selected diagnostic function, and then communicate with the vehicle's ECU to perform the diagnostic function based on the interactive mode.

[0127] 2. If the ECU flashing function is executed, and the interactive mode configuration table shows that it is a send multiple receive one mode, the diagnostic device first sends a command request to send multiple receive one, and the ECU will reply how many frames it supports to send before receiving one frame, such as sending 8 frames of data and receiving one frame of reply. Then the diagnostic device can directly send 8 frames of data and then receive one frame of ECU reply. In this way, the time of receiving multiple ECU replies can be reduced and the efficiency of data transmission can be improved.

[0128] 3. If it is a vehicle fault code reading function, the interactive mode configuration table can be queried to find out that it is a multiple-send and multiple-receive mode. The diagnostic device can then send fault code reading commands to multiple ECUs, and then receive the fault code data replied by each ECU within the maximum waiting time. This avoids the problem of long waiting time when reading ECUs one by one in sequence.

[0129] 4. Other diagnostic functions are in send-receive-one mode by default, which means the diagnostic device sends a command and waits for the ECU to reply. No other diagnostic commands will be sent before receiving the ECU reply. This is generally used in scenarios with a certain diagnostic sequence, such as reading the fault code first and then clearing the fault code function.

[0130] Therefore, the interaction mode is specified according to different diagnostic function scenarios. For example, when a single ECU executes multiple diagnostic functions, the send-one-receive-one mode can be selected. When flashing requires the transmission of a large amount of data, the send-multiple-receive-one mode can be selected. When multiple ECUs need to be accessed at the same time, the send-multiple-receive-multiple mode can be used. This can greatly improve the data transmission efficiency and the success rate of the diagnostic function execution.

[0131] In this embodiment, multiple diagnostic function instructions to be executed are grouped by dividing the number of frames, which effectively reduces the amount of data for each interaction, optimizes the sending and receiving process, improves the overall efficiency, and repeats the sending and receiving steps to ensure that even if the response of a certain instruction is delayed or lost, a complete data set can still be obtained by sending subsequent instructions, thereby enhancing the stability of the system. By collecting the function instruction reply data from the target electronic control unit multiple times, cross-validation can be performed to reduce errors caused by a single feedback and improve the accuracy of the final diagnostic data. This mode can flexibly adapt to different types of electronic control units, support rapid response to different diagnostic needs, and has good scalability. As a result, the efficiency, stability and accuracy of the diagnostic process can be significantly improved, while solving various technical problems existing in the traditional diagnostic mode.
