Description

[0002] In the field of vehicle diagnostics, with the gradual popularization of ODX (Open Diagnostic Data Exchange) diagnostic technology, many OEMs have adopted it as the main method for vehicle diagnostics.

[0003] However, the current method of generating diagnostic data results in an extremely inefficient and time-consuming diagnostic process. In real-world diagnostic scenarios, users often only want to diagnose ECUs (Electronic Control Units) with fault codes, while those ECUs that are functioning normally do not require diagnostic operations. However, the current standard procedure requires downloading a complete diagnostic data package for the entire vehicle every time a diagnostic is performed, regardless of the ECU's status. This data package typically reaches tens of megabytes in size. This means that a significant amount of time is spent downloading and parsing the data package each time a vehicle is diagnosed. This problem is particularly pronounced in scenarios with poor network conditions, not only making the diagnostic process exceptionally slow and significantly impacting work efficiency, but also consuming substantial network resources and increasing unnecessary costs and time.

[0004] In summary, optimizing the way vehicle diagnostic data is generated is a pressing technical problem that needs to be solved. Summary of the Invention

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Current vehicle fault diagnosis procedures often require downloading a complete diagnostic data package for the entire vehicle during each diagnosis, regardless of the electronic control unit's status. This data package typically reaches tens of megabytes in size. This means that a significant amount of time is spent downloading and parsing the data package during each vehicle diagnosis. This problem is particularly pronounced in scenarios with poor network conditions, not only making the diagnostic process extremely slow and significantly impacting work efficiency, but also consuming substantial network resources and increasing unnecessary costs and time. Therefore, this application provides a vehicle diagnostic data generation method, apparatus, device, and storage medium that optimizes the generation of vehicle diagnostic data.

[0050] See Figure 1 and Figure 2 As shown, this embodiment of the invention discloses a method for generating vehicle diagnostic data, applied to in-vehicle equipment, including:

[0051] Step S11: After the diagnostic software starts, it determines the first electronic control unit list through the target configuration word obtained by the vehicle gateway, and sends a fault code reading command to the corresponding electronic control unit based on the first electronic control unit list; the target configuration word is a configuration word that represents the installation status based on the installation status of the electronic control unit on the target vehicle.

[0052] In this embodiment, after the diagnostic software starts, it sends an electronic control unit (ECU) retrieval command to the vehicle gateway. The vehicle gateway then parses the target configuration word (EcuConfigCode) based on the ECU retrieval command and determines a first list of ECUs based on the parsing result. This first list represents the ECUs included in the vehicle.

[0053] It should be noted that the target configuration word is a configuration word representing the installation status, determined based on the number of electronic control units (ECUs) installed and a preset ECU sequence arrangement rule. The number of ECUs installed reflects the total number of ECUs actually installed in the vehicle. The preset ECU sequence arrangement rule refers to the pre-defined rules governing the position of each ECU in the target configuration word. Through this rule, each ECU has a specific position and representation in the configuration word. It can be understood that one byte has 8 bits, and each bit can represent a specific ECU; therefore, the state of each bit indicates whether a particular ECU exists in a particular vehicle. For example, as... Figure 3As shown, assuming a bit is "1" to indicate that the vehicle contains this electronic control unit (ECU), and a bit is "0" to indicate that the vehicle does not contain this ECU. That is, if a vehicle has 8 ECUs, then one byte is needed to represent the target configuration word indicating the installation status of the ECUs. If the order of the ECUs in the target configuration word is set as EMS (Engine Management System), VCU (Vehicle Control Unit), GW (Gateway), BCM (Body Control Module), TCU (Transmission Control Unit), ESC (Electronic Stability Control), FCS (Fuel Cell System), and BMSH (Battery Management System for Hybrid), and the vehicle does not have VCU and BMSH, then the target configuration word in binary is 1011 1110, and in hexadecimal it is 0xBE.

[0054] Furthermore, after obtaining the first list of electronic control units (ECUs), the vehicle gateway sends fault code reading commands to the corresponding ECUs via a polling method based on the first list, so as to perform corresponding reading operations on the ECUs using the fault code reading commands. It should be noted that fault codes are codes analyzed by the vehicle's ECUs after a vehicle malfunction, mainly used to reflect problems in the vehicle's internal systems. Moreover, the polling method is an orderly and efficient communication strategy, ensuring that each ECU receives the fault code reading command sequentially, avoiding information transmission chaos and omissions.

[0055] In this embodiment, by sending fault code reading commands, the vehicle gateway can perform corresponding reading operations on each electronic control unit (ECU). Upon receiving the command, the ECU will feed back its stored fault code information to the vehicle gateway according to a preset communication protocol and instruction requirements. The fault code reading command can be a 19 service command, where 19 is the service ID for UDS (Unified Diagnostic Services) diagnostics, and the 19 service is specifically used to read fault codes from vehicle ECUs.

[0056] Step S12: Determine the fault configuration word based on the fault code reading command, the preset logic calculation rules, and the target configuration word, and send the fault configuration word to the server so that the server can use the fault configuration word to determine the vehicle diagnostic data packet; the fault configuration word is the configuration word of the electronic control unit that records the fault code in the first electronic control unit list.

[0057] In this embodiment, the electronic control units containing fault codes in the first electronic control unit list are determined based on the fault code reading command, and the fault configuration word (i.e., EcuConfigCodeWithDtc) is determined based on the electronic control unit containing the fault code, the target configuration word, and preset logical calculation rules. For example, as Figure 4 As shown, in the process of determining the fault configuration word, the bits representing electronic control units without fault codes are set to "0" and the bits containing fault codes are set to "1" according to the order of electronic control units defined in the target configuration word. Then, an "AND" operation is performed with the target configuration word to obtain the corresponding fault configuration word.

[0058] Step S13: Obtain the vehicle diagnostic data packet sent by the server, and trigger corresponding diagnostic operations based on the vehicle diagnostic data packet.

[0059] In this embodiment, the diagnostic software obtains the vehicle diagnostic data packet (PDX, Packaged ODX, i.e., packaged ODX data) sent by the server, parses the vehicle diagnostic data packet, and obtains the relevant electronic control unit information in the diagnostic data packet through the target object (i.e., LOGICAL-LINK) in the target vehicle electronic control unit file (i.e., ODX-V file), and forms the vehicle topology with this information. The target vehicle electronic control unit file can be as follows: Figure 5 As shown, the files in the vehicle diagnostic data package can be as follows: Figure 6 As shown, the vehicle topology can be as follows: Figure 7 As shown. It should be noted that, Figure 7In this code, BX11-A2 is the vehicle model designation, VIN (Vehicle Identification Number) is LB6512FG541651462, Hybrid_CAN is the hybrid power domain, Chassis_CAN is the chassis domain, and Body_CAN is the body domain. Different CANs (Controller Area Networks) represent different domains, and the electronic control units in the vehicle can be divided into different domains according to their functions. Next, the diagnostic software parses the ODX file and the target open test sequence exchange format file (OTX file), and determines the corresponding diagnostic data and diagnostic scripts based on the parsing results, triggering corresponding diagnostic operations according to the diagnostic data and diagnostic scripts. Furthermore, diagnostic operations include, but are not limited to, generating diagnostic reports and providing corresponding fault solutions.

[0060] As can be seen from the above, after the diagnostic software starts, this application obtains the target configuration word through the vehicle gateway, determines the list of first electronic control units, and sends a fault code reading command to the electronic control units; based on the fault code reading command, preset logical calculation rules, and the target configuration word, it determines the fault configuration word and sends it to the server, which then determines the vehicle diagnostic data packet accordingly; finally, it obtains the vehicle diagnostic data packet sent by the server to trigger the corresponding diagnostic operation. In this way, this application can optimize the generation method of vehicle diagnostic data, thereby improving the efficiency of diagnosis.

[0061] Further, see Figure 8 As shown in the illustration, this application also provides a vehicle diagnostic data generation method, applied to a server, including:

[0062] Step S21: Obtain the fault configuration word sent by the diagnostic software; the fault configuration word is a configuration word determined by the vehicle device based on the fault reading command, preset logical calculation rules, and target configuration word; wherein, the fault reading command is a fault code reading command sent by the vehicle device to the corresponding electronic control unit through the vehicle gateway and using the first electronic control unit list determined based on the target configuration word after the diagnostic software is started; the target configuration word is a configuration word representing the installation status of the electronic control unit on the target vehicle, and the fault configuration word is a configuration word that records the electronic control units with fault codes in the first electronic control unit list.

[0063] Step S22: Parse the fault configuration word to obtain the second electronic control unit list.

[0064] In this embodiment, the server uses a specific parsing algorithm to parse the acquired fault configuration words. Since the fault configuration words are generated according to certain rules and formats, the server needs to parse their content according to these rules. During the parsing process, the server may analyze the fault configuration words according to preset logical rules and algorithms to determine the second electronic control unit (ECU) list. Furthermore, the second ECU list provides an important basis for subsequent diagnostic data processing; the server can use this list to further determine the relevant content information of the vehicle diagnostic data package.

[0065] Step S23: Determine the vehicle diagnostic data package based on the second electronic control unit list, and send the vehicle diagnostic data package to the diagnostic software so that the diagnostic software can obtain the vehicle diagnostic data package and trigger corresponding diagnostic operations based on the vehicle diagnostic data package.

[0066] In this embodiment, the target diagnostic data file (i.e., an ODX-d file, a file used to describe diagnostic data) and the target Open Test Sequence Exchange Format file (i.e., an OTX file) are determined from a preset diagnostic database based on the second electronic control unit list. Furthermore, the process of determining the relevant files from the preset diagnostic database based on the second electronic control unit list is performed automatically by the server, making it more convenient for users to diagnose faulty vehicles and systems. Additionally, the target objects in the initial vehicle electronic control unit file are initialized using the second electronic control unit list, and electronic control units containing fault codes are determined based on the target objects. Finally, the target vehicle electronic control unit file is determined based on the initial vehicle electronic control unit file and the electronic control units containing fault codes.

[0067] Ultimately, in this embodiment, the vehicle diagnostic data package is determined based on the target diagnostic data file, the target open test sequence exchange format file, and the target vehicle electronic control unit file.

[0068] As can be seen from the above, this application obtains the fault configuration word through the server, parses it to obtain the list of second electronic control units, and then determines the vehicle diagnostic data package and sends it to the diagnostic software. After the diagnostic software starts, the on-board equipment determines the fault configuration word based on the fault reading command, preset logical calculation rules, and target configuration word, providing the server with accurate diagnostic basis. The server's parsing of the fault configuration word further clarifies the fault information, laying the foundation for subsequent diagnostic data processing. By determining the vehicle diagnostic data package based on the list of second electronic control units, the server can selectively integrate relevant data, making the diagnostic data package more concise and efficient. In this way, this application not only improves diagnostic efficiency but also optimizes resource utilization.

[0069] Accordingly, see Figure 9As shown, this application provides a vehicle diagnostic data generation device, applied to in-vehicle equipment, including:

[0070] The fault reading module 11 is used to determine the first electronic control unit list by obtaining the target configuration word through the vehicle gateway after the diagnostic software is started, and to send a fault code reading command to the corresponding electronic control unit based on the first electronic control unit list; the target configuration word is a configuration word that represents the installation status based on the installation status of the electronic control unit on the target vehicle.

[0072] The diagnostic trigger module 13 is used to obtain the vehicle diagnostic data packet sent by the server, and to trigger corresponding diagnostic operations based on the vehicle diagnostic data packet.
