[0002] With the development of automobile intelligence, vehicle functions are becoming more and more rich. Therefore, before a vehicle is delivered from a general assembly workshop, the vehicle controller needs to be subjected to a delivery electrical detection to complete software flashing, configuration writing, version checking, and clearing of read fault codes of the vehicle controller, so as to ensure that the vehicle version is consistent and the software, network security and other functions are normal.

[0003] At present, when the general assembly line of a vehicle performs electrical detection on the vehicle, an external electrical detection device is mainly used to connect the on-board diagnostics (OBD) port of the vehicle, and an electrical detection program is manually triggered. However, the external electrical detection device cannot collect electrical detection process data of the vehicle during the electrical detection process.

[0084] The technical solutions in the embodiments of the present application will be described below in detail with reference to the accompanying drawings in the embodiments of the present application.

[0085] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. The association relationship between the associated objects is described by "and / or", which means that there can be three kinds of relationships, for example, A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b, or c, can represent a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0086] In addition, unless otherwise stated, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish a plurality of objects, and are not used to limit the size, content, order, time sequence, priority or importance of the plurality of objects. For example, the second file and the second file are only used to distinguish different files, and do not mean that the sizes, contents, priorities or importance of the two files are different.

[0087] FIG. 1 schematically shows a production line of a vehicle. As shown in FIG. 1, the production line can include an assembly production line, a detection line, and a vehicle off-line. The assembly production line is used to assemble the vehicle, the detection line is used to detect the vehicle coming down from the assembly production line, and the vehicle off-line is used to off-line and warehouse the vehicle coming down from the detection line. The vehicle needs to go through a plurality of stations on the production line to complete assembly and detection, and finally enter the warehouse.

[0088] Referring to FIG. 1, the total assembly production line can include, but is not limited to, the following stations: chassis assembly station, battery installation & safety detection station, software flashing station, seat & door installation station, four-in-one filling station, configuration writing & function test station. As shown in FIG. 1, the detection line includes, but is not limited to, the following stations: air spring calibration station, four-wheel alignment + headlamp detection station, hub test station, charging detection + on-board diagnostics (OBD) detection station, head up display (HUD) calibration station, autonomous driving solution (ADS) calibration station. The vehicle off-line includes, but is not limited to, the following stations: rain test station, dynamic road test station, commercial electrical inspection station, aging test station, vehicle warehousing. Among them, the software flashing station, the configuration writing & function test station and the commercial electrical inspection station are electrical inspection stations. The stations and electrical inspection stations on the production line shown in FIG. 1 are only an example, and the embodiments of the present application do not limit this.

[0089] However, with the development of automobile intelligence, the functions of vehicles are becoming more and more rich, so before the vehicle off-line, the controller inside the vehicle needs to be off-line electrical inspection, complete the software flashing, configuration writing, version checking of the controller, clear reading fault code and other functions, to ensure that the vehicle off-line vehicle version is consistent, and the software, network security and other functions are normal. Therefore, the production line can perform electrical inspection test on the controller of the vehicle when the vehicle is in the electrical inspection station of the production line.

[0090] Currently, the production line of the vehicle mainly uses external electrical inspection equipment to connect the OBD port of the vehicle when performing electrical inspection on the vehicle, and manually triggers the electrical inspection program. During the electrical inspection process, the external electrical inspection equipment can collect the diagnostic messages generated during the electrical inspection process of the vehicle, but cannot collect the electrical inspection process data of the vehicle. Among them, the electrical inspection process data can include the vehicle log recorded by the gateway controller of the vehicle during the electrical inspection process, and the component log recorded by the controller of the vehicle during the electrical inspection process. Therefore, during the analysis of the vehicle off-line electrical inspection problem, professionals need to use professional equipment to collect the electrical inspection process data. For example, in general, the vehicle log generated during the electrical inspection process of the vehicle needs to be collected by external equipment such as CANoe, and the component log needs to be collected by a notebook computer using special software, and different components have different collection methods. In this case, the way of collecting the electrical inspection process data generated during the electrical inspection process of the vehicle by professional equipment has the problems of high manual time cost, etc., thereby leading to low efficiency of collecting the electrical inspection process data.

[0091] Therefore, the embodiments of the present application provide a vehicle electrical inspection method, device and system to improve the collection efficiency of electrical inspection process data. The method and device are based on the same technical concept. Since the principles of the method and device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again. In addition, in each embodiment of the present application, the terms and / or descriptions between the embodiments are consistent and can be mutually referred to if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0092] In the embodiments of the present application, the controller inside the vehicle can be one or multiple. That is, the vehicle contains one or more controllers. The electrical inspection log refers to the log generated by the vehicle during the electrical inspection process, which records the data generated by the vehicle during the electrical inspection process. The electrical inspection log is composed of diagnostic messages, vehicle logs and component logs. The vehicle log refers to the log recorded by the gateway controller in the vehicle during the electrical inspection process, which records the interaction data between the gateway controller and the controller hung on the gateway controller. The component log refers to the log recorded by each controller in one or more controllers during the electrical inspection process, which records the running of each controller itself and the interaction data between each controller and the gateway controller.

[0093] The scheme provided by the present application will be introduced in combination with the drawings and specific embodiments. In the corresponding drawings of each embodiment of the present application, optional steps are represented by dashed lines.

As shown in FIG. 2, in the application scenario, the production management system 100, the server 200 and the vehicle 300 can be included. The vehicle 300, the server 200 and the production management system 100 can communicate through a network, and the vehicle 300 is located on the production line managed by the production management system 100. In the embodiments of the present application, the functions implemented by the server 200 in the application scenario shown in FIG. 2 can also be implemented by a terminal device or an electrical inspection device, which is not limited herein. For example, the network can be a local area network.

[0095] Some or all functions of the vehicle 300 are controlled by a computing platform 350 (or computer system) of the vehicle 300. The computing platform 350 can include at least one processor 351 that can execute instructions 354 stored in a non-transitory computer readable medium, such as a memory 353, to implement functions of the vehicle 300. In some embodiments, the computing platform 350 can also be a plurality of computing devices that control individual components or subsystems of the vehicle 300 in a distributed manner. The processor 351 can be any conventional processor, such as a central processing unit (CPU). Alternatively, the processor 351 can also include a graphics processing unit (GPU), a field programmable gate array (FPGA), a system on chip (SoC), an application specific integrated circuit (ASIC), or a combination thereof.

[0096] Optionally, the vehicle 300 described above can be a car, a truck, a motorcycle, a bus, a ship, an airplane, a helicopter, a lawnmower, an amusement park vehicle, a construction equipment, a trolley, a golf cart, a train, etc., and the embodiments of the present application do not make special limitations. In a possible implementation, the vehicle 300 can be a new energy vehicle, including a pure electric vehicle, a hybrid electric vehicle, a fuel cell electric vehicle, etc. For an electric vehicle, it can be a two-wheel drive electric vehicle or a four-wheel drive electric vehicle, and the embodiments of the present application do not make special limitations.

[0097] The structure of the vehicle in FIG. 2 should not be understood as a limitation of the embodiments of the present application.

[0098] The vehicle electrical inspection method of the embodiments of the present application can be implemented by an electrical inspection module of the vehicle, which can be a standalone device, a chip or component in the vehicle 300 shown in FIG. 2, or a software module (such as an application). The software module can be deployed on a related vehicle-mounted device of the vehicle 300, such as a car machine system (such as a cockpit domain controller (CDC)) integrated in the computing platform 350 of the vehicle 300, or deployed on a control unit of other components of the vehicle, and the embodiments of the present application do not make special limitations on the product form and deployment manner of the electrical inspection module.

[0099] In the embodiments of the present application, the electrical inspection module of the vehicle can also be referred to as an in-vehicle electrical inspection instrument, and the electrical inspection module can be an electrical inspection function platform of the car machine system.

[0100] The vehicle can include at least one display screen. The electrical inspection module can implement the vehicle electrical inspection method of the embodiments of the present application, and can also display the electrical inspection process and electrical inspection result of the vehicle on any one of the at least one display screen to inform the user of the electrical inspection process of the vehicle.

[0101] In some embodiments, the electrical inspection module is a separate device in the vehicle. As shown in FIG. 3, the operating system of the electrical inspection module of the vehicle can install and run a first application (application, APP) for electrical inspection testing of the vehicle. The electrical inspection module can display an icon of the installed first application on the associated vehicle display screen (for example, the center control screen). In addition, during the running of the first application, the electrical inspection module can display the user interface of the first application on the vehicle display screen.

[0102] The production management system can control the line operation according to the line body beat of the production line. The vehicle will run between multiple stations on the production line as the production line operates. For example, when the vehicle is on the assembly line of the production line, after completing the assembly and safety detection of the parts at the battery installation & safety detection station, the vehicle will run to the software flashing station with the production line. When the vehicle runs to the electrical inspection station with the production line, the user can perform the power-on processing on the vehicle to start the electrical inspection module. For example, after the vehicle is powered on, the first application icon will be displayed on the vehicle display screen. The vehicle infotainment system can start the electrical inspection module and run the first application in response to the user executing the start operation on the first application icon on the vehicle display screen. After the electrical inspection module is successfully connected to the network, it can communicate with the server and the production management system through the network. After connecting to the network, the electrical inspection module can perform electrical inspection testing on the vehicle. For example, as shown in FIG. 4, the electrical inspection module can perform electrical inspection testing on the vehicle through the following steps.

[0103] S401: The electrical inspection module obtains an electrical inspection task file.

[0104] The electrical inspection task file can be an electrical inspection program script, and the electrical inspection task file can include at least one electrical inspection item.

[0105] In some embodiments, the electrical inspection module can obtain the electrical inspection task file from the server after connecting to the network. For example, when the vehicle is at the electrical inspection station and the vehicle is connected to the network, the electrical inspection module can send an electrical inspection request to the server. The electrical inspection request is used to request the electrical inspection task file, and the electrical inspection request includes but is not limited to: the vehicle identification number (VIN) of the vehicle, and the station information.

[0106] For example, as shown in FIG. 5, when the vehicle is at the electrical inspection station, the electrical inspection module can further start a first application and display a user interface 500 of the first application on the vehicle display screen. The user interface 500 at least includes a "start electrical inspection" control 501 and a "get electrical inspection task file" control 502. The "start electrical inspection" control 501 is used to prompt the user to perform electrical inspection test on the vehicle. The "get electrical inspection task file" control 502 is used to prompt the user to obtain the electrical inspection task file for performing electrical inspection test on the vehicle. After the electrical inspection module establishes a connection with the network, the electrical inspection module can send an electrical inspection request to the server in response to the user's click operation on the "get electrical inspection task file" control 502.

[0107] After receiving the electrical inspection request from the electrical inspection module of the vehicle, the server can determine the electrical inspection task file of the vehicle according to the vehicle identification code in the electrical inspection request. For example, the server can determine one or more controllers in the vehicle corresponding to the vehicle identification code for performing electrical inspection test, and determine the station information corresponding to the vehicle identification code. The one or more controllers in the vehicle can include at least one of the following controllers: an intelligent driving domain controller (for example, a mobile data center (MDC)), a vehicle domain controller (VDC), a CDC, a telematics box (TBOX), and other controllers. The other controllers can be controllers in the vehicle other than the MDC, VDC, CDC, and TBOX. The server can determine the electrical inspection task file of the vehicle according to the one or more controllers in the vehicle for performing electrical inspection test and the station information corresponding to the vehicle identification code, and send the electrical inspection task file to the electrical inspection module. The electrical inspection module receives the electrical inspection task file from the server.

[0108] For example, when it is determined according to the station information that the vehicle is at the software flashing station, the electrical inspection task file is used to perform corresponding software flashing and diagnostic services on the one or more controllers in the vehicle. For another example, when it is determined according to the station information that the vehicle is at the write configuration & function test station, the electrical inspection task file is used to perform corresponding write configuration and function test on the one or more controllers in the vehicle.

[0109] S402: The electrical inspection module performs electrical inspection test on the one or more controllers in the vehicle according to the electrical inspection task file, and generates an electrical inspection log.

[0110] The electrical inspection log includes at least one of a diagnostic message and a diagnostic log. The diagnostic log includes, but is not limited to, a vehicle log and a component log. The diagnostic message may, for example, include, but is not limited to, interaction data between the electrical inspection module and the gateway controller during the electrical inspection of the vehicle, and an electrical inspection result. The vehicle log records interaction data between the gateway controller and a lower-hanging controller during the electrical inspection of the vehicle. The lower-hanging controller is a controller that is directly connected to the gateway controller and exchanges data with the gateway controller, such as an electric power steering (EPS) system. The component log records interaction data between each of one or more controllers and the gateway controller during the electrical inspection of the vehicle, and a log of the operation of each controller itself.

[0111] In some embodiments, after receiving the electrical inspection task file, the electrical inspection module can parse the electrical inspection task file to obtain at least one electrical inspection item. The electrical inspection module can perform electrical inspection testing on one or more controllers according to each of the at least one electrical inspection item until all electrical inspection items are completed. For example, the electrical inspection module can generate a corresponding diagnostic instruction for each of one or more controllers according to the content of the current electrical inspection item. The diagnostic instruction may, for example, include an internet protocol (IP) address of the controller corresponding to the diagnostic instruction. The electrical inspection module can send the diagnostic instruction to the gateway controller, and the gateway controller can forward the diagnostic instruction to the controller corresponding to the IP address of the diagnostic instruction according to a routing table. The controller receiving the diagnostic instruction can perform a corresponding operation according to the diagnostic instruction, generate a diagnostic response, and reply the diagnostic response to the electrical inspection module through the gateway controller. The electrical inspection module continues to perform the above process for the next electrical inspection item until all electrical inspection items are completed. For example, the diagnostic instruction and the diagnostic response may, for example, be transmitted in the form of a diagnostic over internet protocol (DOIP) message based on an IP protocol, or in the form of a diagnostic CAN message based on a controller area network (CAN) bus protocol when transmitted between the electrical inspection module and one or more controllers. For example, during the electrical inspection, the electrical inspection module and the gateway controller send diagnostic DOIP messages, and the gateway controller and the lower-hanging controller send diagnostic DOIP messages and diagnostic CAN messages.

[0112] For example, when the vehicle contains a controller, and the electrical inspection station where the vehicle is located is a software flashing station, the electrical inspection task file includes a software package that needs to be flashed on the controller, and at least one electrical inspection item includes but is not limited to: a filling certificate key item, a software flashing item. The electrical inspection module can generate a first diagnostic instruction according to the filling certificate key item. The first diagnostic instruction is used to instruct the controller to perform filling certificate key operations. The electrical inspection module can send the first diagnostic instruction to the controller through the gateway controller; the controller performs filling digital certificate and key operations in response to the received first diagnostic instruction, and generates a first diagnostic response. The controller can return the first diagnostic response to the electrical inspection module through the gateway controller. The electrical inspection module can determine that the filling certificate key item is completed according to the first diagnostic response, and can generate a second diagnostic instruction according to the software flashing item. The second diagnostic instruction is used to instruct the controller to perform software flashing operations. The controller performs pre-programming, main programming, post-programming and other operations in response to the received second diagnostic instruction, and generates a second diagnostic response. The pre-programming includes but is not limited to the following operations: checking whether it is in a flashing environment, closing communication, disabling application messages, reducing load, main programming includes software flashing operation, post-programming includes but is not limited to the following operations: reset (such as clearing fault codes), software consistency verification, software compatibility judgment. The controller can send the second diagnostic response to the electrical inspection module through the gateway controller. The fault code is a fault identifier of the controller defined internally in the controller. The fault code can indicate that the controller loses communication, short circuit or open circuit failure.

[0113] For another example, when the electrical inspection station where the vehicle is located is a write configuration & function test station, at least one electrical inspection item includes but is not limited to: a write configuration item, a routine learning item. The electrical inspection module can generate corresponding diagnostic instructions according to the write configuration item and the routine learning item respectively. The electrical inspection module sends the diagnostic instructions to the controller. The controller performs write VIN, configuration word, control seat, tailgate, steering wheel self-learning and other actions in response to the received diagnostic instructions, and generates a diagnostic response. The controller can return the diagnostic response to the electrical inspection module.

[0114] For another example, when the electrical inspection station where the vehicle is located is a write configuration & function test station, at least one electrical inspection item includes but is not limited to: a write configuration item, a routine learning item. The electrical inspection module can generate corresponding diagnostic instructions according to the write configuration item and the routine learning item respectively. The electrical inspection module sends the diagnostic instructions to the controller. The controller performs write VIN, configuration word, control seat, tailgate, steering wheel self-learning and other actions in response to the received diagnostic instructions, and generates a diagnostic response. The controller can return the diagnostic response to the electrical inspection module.

[0115] During the electrical inspection process, the electrical inspection module can record interaction data between the electrical inspection module and the gateway controller, and synchronously store the recorded interaction data in a local storage area of the electrical inspection module. The interaction data between the electrical inspection module and the gateway controller can include at least one of a diagnostic instruction and a diagnostic response. For example, when the electrical inspection module parses the electrical inspection task file to obtain at least one electrical inspection item, the electrical inspection module can start recording the interaction data between the electrical inspection module and the gateway controller. When the electrical inspection module completes all electrical inspection items, the electrical inspection module can stop recording the interaction data between the electrical inspection module and the gateway controller. During the recording of the interaction data, the electrical inspection module can synchronously store the recorded interaction data in a storage area of the controller in which the electrical inspection module is located.

[0116] During the electrical inspection process, the electrical inspection module can also determine an electrical inspection result according to the recorded interaction data, and synchronously store the determined electrical inspection result in the local storage area of the electrical inspection module. For example, the electrical inspection module can determine the electrical inspection result according to the diagnostic response or the diagnostic message in the interaction data. For example, when the electrical inspection module determines that the response content in the diagnostic response indicates that the software configuration in the controller meets the test requirements, the electrical inspection module determines that the electrical inspection result of the controller corresponding to the diagnostic response is electrical inspection success. For another example, when the electrical inspection module determines that the response content in the diagnostic response indicates that the software configuration in the controller does not meet the test requirements, the electrical inspection module determines that the electrical inspection result of the controller corresponding to the diagnostic response is electrical inspection failure. For another example, after the electrical inspection module sends a diagnostic message, the electrical inspection module determines that no diagnostic response corresponding to the diagnostic message is received, and the electrical inspection module can determine that the electrical inspection result of the controller corresponding to the diagnostic message is electrical inspection failure.

[0117] After the electrical inspection ends, the electrical inspection module can generate a diagnostic message according to the recorded interaction data between the electrical inspection module and the gateway controller and the electrical inspection result. The diagnostic message can be stored in the local storage area of the electrical inspection module.

[0118] As an example, during the electrical inspection process, when the electrical inspection module determines the electrical inspection result, the electrical inspection module can also display the electrical inspection result on the vehicle display screen. For example, as shown in FIG. 6, at a first time, the electrical inspection module performs electrical inspection testing on the controller in the vehicle based on electrical inspection item 1, and obtains an electrical inspection result of electrical inspection item 1 as success. At a second time, the electrical inspection module performs electrical inspection testing on the controller based on electrical inspection item 2, and obtains an electrical inspection result of electrical inspection item 2 as failure. The first time is earlier than the second time. While the electrical inspection module displays the electrical inspection result on the vehicle display screen, the electrical inspection module can also send the electrical inspection result to the production management system or the server. The server or the production management system can display the electrical inspection result on the display screen related thereto.

[0119] When the electrical inspection module starts recording interaction data, the electrical inspection module can also instruct the gateway controller to record interaction data between the gateway controller and the lower-hung controller, and generate a vehicle log. For example, when the electrical inspection module starts recording interaction data, the gateway controller simultaneously collects and encapsulates messages of the CAN bus, local interconnect network (LIN) bus, etc. of the lower-hung vehicle body, power, etc. to obtain a vehicle log. For example, when the gateway controller is a VIU, the VIU can collect bus mirror data of the lower-hung LIN node and CAN node, and then encapsulate the bus mirror data into an Ethernet packet in a bus mirroring protocol definition manner. The format of the Ethernet packet complies with the AutoSar specification, and the Ethernet packet is the vehicle log.

[0120] After obtaining the vehicle log, the gateway controller can also store the vehicle log in the internal storage space of one or more controllers. For example, when the gateway controller is a VIU, the VIU can also store the collected and encapsulated vehicle log in the internal storage space of the CDC or VDC in a bus message mirroring multicast manner. The CDC and VDC have multicast ports and can receive the vehicle log encapsulated by the VIU.

[0121] During the electrical inspection process, each of the one or more controllers can record interaction data between each controller and the gateway controller, and a log of the running of the controller itself, to generate a component log. The one or more controllers can store the generated component log in the storage space of the corresponding controller. For example, the component log of the CDC is stored in the storage space of the CDC, the component log of the MDC is stored in the storage space of the MDC, the component log of the TBOX is stored in the storage space of the TBOX, and the component log of the VDC is stored in the storage space of the VDC.

[0122] S403: The electrical inspection module sends the electrical inspection log to the server. The server receives the electrical inspection log from the electrical inspection module.

[0123] In some embodiments, when the vehicle electrical inspection test ends, there are two cases of the electrical inspection result of the vehicle: one is electrical inspection failure, and the other is electrical inspection success. When the electrical inspection result is electrical inspection success, the electrical inspection module can send a diagnostic packet to the server. When the electrical inspection result is electrical inspection failure, the electrical inspection module can send a diagnostic packet and a diagnostic log to the server. The sending process of the electrical inspection log is described below according to the above two cases.

[0124] Case 1: The electrical inspection result is electrical inspection success.

[0125] In some embodiments, after the electrical inspection test ends, the electrical inspection module can determine the content of the electrical inspection log sent to the server according to the electrical inspection result, and can also send a diagnosis message to the server, and the server can determine whether the diagnosis log is needed according to the electrical inspection result in the diagnosis message.

[0126] As an example, after the electrical inspection test ends, the electrical inspection module can send a diagnosis message to the server. The server can determine whether the diagnosis log is needed from the electrical inspection module according to the electrical inspection result in the diagnosis message. For example, when the electrical inspection result in the diagnosis message is electrical inspection success, the server can determine that the diagnosis log is not needed.

[0127] As another example, when the electrical inspection result is electrical inspection success, the electrical inspection module can determine that the electrical inspection log sent to the server only contains the diagnosis message and does not contain the diagnosis log. The electrical inspection module can send the diagnosis message to the server.

[0128] After receiving the diagnosis message, the server can send the electrical inspection result in the diagnosis message to the production management system. After receiving the electrical inspection result, the production management system can control the line operation according to the electrical inspection result. For example, when the electrical inspection result is electrical inspection success, the production management system can control the line operation to move the vehicle from the electrical inspection station to the next station for assembly detection.

[0129] Case 2: The electrical inspection result is electrical inspection failure.

[0130] In some embodiments, after the electrical inspection test ends, the electrical inspection module can determine the content of the electrical inspection log sent to the server according to the electrical inspection result, and can also send a diagnosis message to the server, and the server can determine whether the diagnosis log is needed according to the electrical inspection result in the diagnosis message.

[0131] As an example, the electrical inspection module can send a diagnosis message to the server. After receiving the diagnosis message, the server can also determine whether the vehicle electrical inspection is successful according to the electrical inspection result in the diagnosis message. When the electrical inspection result in the diagnosis message is that the target controller in one or more controllers fails in electrical inspection, the server can send a log calling request to the electrical inspection module. The log calling request is used to request the diagnosis log.

[0132] The electrical inspection module can obtain the diagnostic logs from the one or more controllers according to the log call request after receiving the log call request, and send the diagnostic logs to the server. The diagnostic logs can include vehicle logs and component logs. For example, the electrical inspection module can perform security authentication with the one or more controllers, and obtain the diagnostic logs from the one or more controllers after the security authentication is successful. For another example, the electrical inspection module can also perform authentication authentication with the one or more controllers, and obtain the diagnostic logs from the one or more controllers when it is determined that the electrical inspection module has access to the one or more controllers. The electrical inspection module can obtain the diagnostic logs from the one or more controllers in the following ways.

[0133] The electrical inspection module can call the port of the internal storage area of the target controller to obtain the component logs in the electrical inspection period from the internal storage area of the target controller. The electrical inspection module can also call the port of the internal storage area of the first controller to obtain the vehicle logs in the electrical inspection period from the internal storage area of the first controller. The first controller is a controller in the one or more controllers for storing vehicle logs.

[0134] As another example, when the electrical inspection result is that the electrical inspection of the target controller in the one or more controllers fails, the electrical inspection module can determine that the electrical inspection logs sent to the server include the diagnostic message and the diagnostic logs. The electrical inspection module can obtain the diagnostic logs and send the diagnostic message and the diagnostic logs to the server. The process of the electrical inspection module obtaining the diagnostic logs is the same as that in the above-mentioned embodiments, and will not be described here.

[0135] The server can store the electrical inspection logs after receiving the electrical inspection logs, or can analyze the vehicle according to the electrical inspection logs to obtain a diagnostic result. For example, when the electrical inspection result of the vehicle is determined to be electrical inspection failure, the server can analyze the electrical inspection problem of the vehicle according to the electrical inspection logs of the vehicle, or can analyze the electrical inspection problem of the vehicle in response to a diagnostic operation triggered by a user. The diagnostic operation is used to instruct the server to diagnose and analyze the electrical inspection problem of the vehicle.

[0136] For example, the server can provide the user with the electrical inspection result query service on the display screen associated with the server. As shown in FIG. 7, the server can display a data query interface 710 on the display screen associated with the server. The data query interface 710 at least includes an "input VIN" control 701 and a "query" control 702. In one scenario, the server displays a data query interface 720 in response to the user inputting a VIN, such as 00XXX, in the "input VIN" control 701. The data query interface 720 includes the "input VIN" control 701 displaying 00XXX. The server displays a data query interface 730 in response to the user clicking the "query" control 702. The data query interface 730 at least includes a "diagnostic analysis" control 703 and a display area 704 displaying the electrical inspection result. The display area 704 displays the electrical inspection result as a failed electrical inspection. In this way, the user can query the electrical inspection result of the vehicle with the VIN of 00XXX on the display screen associated with the server. The user can also click the "diagnostic analysis" control 703 in the data query interface 730 to trigger the diagnostic operation. The server performs diagnostic analysis on the electrical inspection problem of the vehicle according to the electrical inspection log in response to the user clicking the "diagnostic analysis" control 703.

[0137] As an example, as shown in FIG. 8, the server can perform diagnostic analysis on the electrical inspection problem of the vehicle according to the electrical inspection log in the following manner.

[0138] S801: The server parses the electrical inspection log to determine the transmission record of the diagnostic message and the message content of the diagnostic message transmitted between the electrical inspection module, the gateway controller, and one or more controllers.

[0139] In some embodiments, the server can obtain the electrical inspection log of the vehicle from the data storage module of the server. The electrical inspection log includes the diagnostic message and the diagnostic log, the diagnostic message includes the diagnostic instruction and the diagnostic response, and the diagnostic log includes the transmission record of the diagnostic instruction and the diagnostic response between the gateway controller and the one or more controllers.

[0140] After obtaining the electrical inspection log, the server can decompress the electrical inspection log and convert the electrical inspection log into a format that can be parsed by CANoe. The server can parse the electrical inspection log in the converted format to determine the transmission record of the diagnostic message and the message content of the diagnostic message. The transmission record of the diagnostic message can include the transmission record of the diagnostic instruction and the transmission record of the diagnostic response, and the message content of the diagnostic message can be the content of the diagnostic instruction or the content of the diagnostic response.

[0141] S802: The server determines the transmission path of the target data according to the transmission record of the diagnostic message.

[0142] The target data is carried in the diagnostic message. For example, the target data is carried in the diagnostic instruction and the diagnostic response.

[0143] In some embodiments, the server can determine the transmission path of the target data among the electrical inspection module, the gateway controller and the target controller according to the diagnostic routing table of the vehicle, the channel correspondence table, the electrical inspection result of the vehicle and the like.

[0144] For example, the server can obtain the configuration information of the whole vehicle network in advance. For example, when the gateway controller is VDC and the lower-hung controller is BMS (power battery pack), the configuration information includes but is not limited to: the diagnostic routing table, the CAN / CAN with flexible data rate (CANFD) / LIN channel correspondence table, the CAN ID, the logical address, the network segment (CANFD_VIU1_EP network segment) where the BMS is located, and the specific channel of the network segment in the whole vehicle CAN data. The server can create an automation script in advance according to the configuration information of the gateway controller. When the server obtains the decompressed electrical inspection log of the vehicle from the data storage module, the server can extract the decompressed electrical inspection log through the automation script to obtain the transmission path of the target data. After obtaining the transmission path of the target data, the server can also display the transmission path of the target data in the visual interface.

[0145] S803: The server determines the transmission interruption position of the target data according to the transmission path of the target data and the set transmission path.

[0146] For example, the transmission path of the target data can be: the electrical inspection module-gateway controller; the set transmission path can be: the electrical inspection module-gateway controller-target controller-gateway controller-electrical inspection module; the server can determine that the transmission interruption position of the target data is the position of the gateway controller, and the server can also determine that the gateway controller does not forward the diagnostic instruction of the electrical inspection module according to the message data on the transmission path of the target data. For another example, the transmission path of the target data can be: the electrical inspection module-gateway controller-target controller; the set transmission path can be: the electrical inspection module-gateway controller-target controller-gateway controller-electrical inspection module; the server can determine that the transmission interruption position of the target data is the target controller, and can determine that the target controller does not respond to the diagnostic instruction.

[0147] S804: The server obtains the failure information related to the target controller on the previous work station of the vehicle in the electrical inspection work station.

[0148] The failure information includes but is not limited to: the assembly failure (such as missing parts, missing installation, skew needle and the like) of the target controller on the previous work station, the failure information such as the untightening of the bonding bolt and the like.

[0149] In some embodiments, the server can send the electrical inspection result to the production management system. When the electrical inspection result is a failure of electrical inspection of a target controller in one or more controllers in the vehicle, the server determines failure information related to the target controller on a preceding station of the electrical inspection station. The production management system sends the obtained failure information to the server.

[0150] S805: The server determines a diagnosis result according to the failure information, the preset electrical inspection problem rule, the message content of the diagnosis message, and the transmission interruption position of the target data.

[0151] In some embodiments, the server can analyze the failure information, the preset electrical inspection problem rule, the message content of the diagnosis message, and the transmission interruption position of the target data based on big data modeling to obtain the diagnosis result. The server can determine the electrical inspection problem according to the message content of the diagnosis message and / or the transmission interruption position of the target data. For example, the server can determine that the target controller does not respond to the diagnosis instruction according to the transmission interruption position of the target data. For another example, when the target data does not have the transmission interruption position, the server can determine the electrical inspection problem according to the message content of the diagnosis message. For example, the server can determine that the target controller fails to write VIN according to the message content of the diagnosis message.

[0152] As an example, the server can match the failure information with the electrical inspection problem to obtain the diagnosis result. For example, when the server determines that the target controller has a needle skew problem in the assembly process according to the transmission interruption position of the target data, the server determines that the target controller does not respond to the diagnosis instruction according to the failure information. The needle skew problem can cause the target controller not to respond. At this time, the needle skew problem in the failure information matches the electrical inspection problem successfully, and the server can determine that the diagnosis result is that the needle skew problem of the target controller causes the target controller to fail to respond to the diagnosis instruction, resulting in the electrical inspection failure of the target controller.

[0153] As another example, the server can also match the electrical inspection problem with the preset electrical inspection problem rule to obtain the diagnosis result. For example, when the matching is successful, the server can know the reason why the target controller or the gateway controller does not respond.

[0154] As another example, the server can match the failure information, the preset electrical inspection problem rule, and the electrical inspection problem identified by the server to determine the diagnosis result. When the matching is successful, the diagnosis result can be the cause of the electrical inspection problem. When the matching fails, the diagnosis result can be that the cause of the electrical inspection problem is not identified.

[0155] As another example, when the server matches the failure information, the preset electrical inspection problem rule, and the electrical inspection problem in sequence, and determines that the matching fails, the server can further match the electrical inspection problem with an electrical inspection problem case library to determine a case similar to the electrical inspection problem. The server can generate a diagnosis result according to the determined case. The diagnosis result can include the case similar to the electrical inspection problem and a difference between the electrical inspection problem and the electrical inspection problem in the case.

[0156] After obtaining the diagnosis result, the server can send the diagnosis result to a user for further processing according to the diagnosis result. The user can be an engineer who can solve the electrical inspection problem or an electrical inspection personnel who performs the electrical inspection on the vehicle. For example, when the diagnosis result obtained by the server only includes the case similar to the electrical inspection problem and does not include a solution, the server can send the diagnosis result to the electrical inspection personnel for processing. For another example, when the diagnosis result includes the electrical inspection problem and a solution to the electrical inspection problem, the server can send the diagnosis result to the engineer for processing the vehicle according to the solution in the diagnosis result.

[0157] In some embodiments, after the electrical inspection test ends, the electrical inspection module can send a diagnosis packet to the server. When the server determines that the electrical inspection result in the diagnosis packet is a target controller electrical inspection failure, the server can perform a rework electrical inspection on the vehicle. For example, the server can perform the rework electrical inspection on the vehicle in the following manner.

[0158] In some embodiments, the server can obtain a first time length from a production management system. The first time length is used to indicate a maximum time length during which the vehicle can be subjected to the rework electrical inspection at the electrical inspection station. For example, after determining that the vehicle fails the electrical inspection, the server can send a time request to the production management system. The time request is used to request the first time length. After receiving the time request, the production management system determines the first time length according to the station information of the vehicle and a line body beat. The production management system can send the first time length to the server. For example, the production management system can interact with an automatic vehicle identification (AVI) system of the vehicle in real time to obtain the station information of the vehicle. For example, the production management system can send a location request to the AVI system of the vehicle. The location request is used to obtain the station information of the vehicle. After receiving the location request, the AVI system can determine the station information of the vehicle by using a radio frequency identification (RFID) technology. The AVI system sends the station information of the vehicle to the production management system. After obtaining the station information of the vehicle and a current line body beat, the production management system determines the first time length.

[0159] The server can also determine a second time length according to the electrical inspection log. The second time length is a time length consumed for performing at least one electrical inspection repair item. As an example, the server can determine at least one electrical inspection failure item of the target controller according to the electrical inspection result in the diagnosis message. The server can select at least one electrical inspection repair item from the at least one electrical inspection failure item according to the priority of the electrical inspection item. For example, the priority of the filling certificate key item is higher than the priority of the software flashing item. As another example, the priority of the writing configuration item is higher than the priority of the routine learning item. The server can determine the second time length according to the at least one electrical inspection repair item. For example, the server can input the at least one electrical inspection repair item into a trained model to obtain the second time length. The trained model is obtained by actively learning, neural network learning, machine learning, or the like, in combination with the actual time consumed by each electrical inspection item in the vehicle electrical inspection process, to train an initial model. The initial required time of each electrical inspection item in the initial model is obtained by bench testing. As another example, the server can also display the electrical inspection failure items in the visual interface, and select at least one electrical inspection repair item from the electrical inspection failure items for repair by the user. The server can determine the second time length required for performing the at least one electrical inspection repair item in response to the operation of the user selecting at least one electrical inspection repair item for repair from the visual interface.

[0160] As an example, when the second time length is less than or equal to the first time length, the server sends a repair request to the electrical inspection module. The repair request is used to instruct the electrical inspection module to perform electrical inspection testing based on the at least one electrical inspection repair item. The at least one electrical inspection repair item is part or all of the at least one electrical inspection failure item.

[0161] After receiving the repair request, the electrical inspection module performs electrical inspection testing on one or more controllers according to the at least one electrical inspection repair item, and generates a repair electrical inspection log. The electrical inspection module sends the repair electrical inspection log to the server. The repair electrical inspection log includes at least one of a repair diagnosis message and a repair diagnosis log. As an example, the electrical inspection module can perform repair on the target controller according to the at least one electrical inspection repair item. The process of the electrical inspection module performing repair on the target controller according to the at least one electrical inspection repair item is the same as the process of the electrical inspection module performing electrical inspection testing on one or more controllers according to the at least one electrical inspection item in the above-described embodiments, and will not be described here.

[0162] In some scenarios, when the repair diagnosis message in the repair diagnosis packet in the repair electrical inspection log indicates that the repair electrical inspection result is a repair failure, the server can further select, from the at least one electrical inspection repair item, an item that can be subjected to repair electrical inspection, and perform repair electrical inspection on the vehicle again until the vehicle electrical inspection is qualified or the second duration of repair is greater than the first duration. In addition, in the embodiments of the present application, in order to avoid the problem of repeated instructions to the controller of the vehicle, causing the controller to be completely disabled, the number of times of repair performed by the server on the vehicle is limited. For example, the server can automatically repair the vehicle at most 3 times.

[0163] For example, when the server performs repair on the vehicle, and the repair electrical inspection result of the vehicle indicates that the electrical inspection fails, the server can obtain, from the electrical inspection module of the vehicle, an electrical inspection log generated by the vehicle during the electrical inspection, and a repair electrical inspection log generated by the vehicle during the repair electrical inspection. The server can analyze the diagnosis packet in the electrical inspection log, the diagnosis log, and the repair diagnosis packet in the repair electrical inspection log, and the repair diagnosis log, to determine the transmission record of the diagnosis packet, the packet content of the diagnosis packet, the transmission record of the repair diagnosis packet, and the packet content of the repair diagnosis packet transmitted between the electrical inspection module and one or more controllers. The server can determine the transmission path of the target data according to the transmission record of the diagnosis packet and the transmission record of the repair diagnosis packet. The target data is carried in the diagnosis packet and the repair diagnosis packet. The server can determine the transmission interruption position of the target data according to the transmission path of the target data and the set transmission path. The server can further obtain failure information related to the target controller of the vehicle on the previous station of the electrical inspection station.
