However, with the advent of intelligent cars, users' demand for intelligent products is constantly increasing, and remote diagnosis of cars is favored by more and more users. Each ECU (Electronic Control Unit) in the vehicle has its own diagnostic module to support offline diagnosis of the vehicle. Each diagnostic module has its own diagnostic message ID and diagnostic strategy, and technicians often need to use relevant vehicle diagnostic data to assist in fault analysis.

[0045] Embodiment 1

[0046] See also Figure 1 , a first embodiment of the present invention provides a method for remote diagnosis of an automobile, the method comprising steps S10-S15:

[0047] Step S10, inputting a diagnostic instruction to a remote diagnostic server, selecting a diagnostic service according to the diagnostic instruction, and sending the diagnostic service to the vehicle terminal;

[0048] The diagnostic instruction includes the target VIN code and the target control unit of the selected target vehicle, wherein the VIN code is the vehicle identification number (Vehicle Identification Number). The VIN code consists of 17 characters, which contains information such as the manufacturer, year, model, body type and code, engine code and assembly location of the vehicle. In this embodiment, the target control unit is an ECU (Electronic Control Unit), also known as a "driving computer" or "on-board computer". Like an ordinary computer, it is composed of a microcontroller (MCU), a memory (ROM, RAM), an input / output interface (I / O), an analog-to-digital converter (A / D), and large-scale integrated circuits such as shaping and driving.

[0049] According to the target VIN code and the target control unit, a diagnostic service is selected and sent to the vehicle terminal to facilitate accurate diagnosis of the vehicle. In this embodiment, the vehicle terminal is a TBOX (Telematics BOX), which is used for remote information processing interaction and communication between the vehicle terminal and the remote diagnosis server.

[0050] Before the step of inputting a diagnostic instruction to a remote diagnostic server, selecting a diagnostic service according to the diagnostic instruction, and sending the diagnostic service to the vehicle terminal, the method further includes:

[0051] A communication connection is established between the automobile database and the remote diagnosis server, and the vehicle information in the automobile database is sent to the remote diagnosis server, wherein the vehicle information includes the model, VIN code, control unit and part number of each vehicle.

[0052] A communication connection is established between the remote diagnosis server and the vehicle-mounted terminal so that the remote diagnosis server communicates with the vehicle-mounted terminal.

[0053] Step S11, translating the diagnostic service into a diagnostic message through the vehicle-mounted terminal, and sending the diagnostic message to a target control unit;

[0054] Specifically, the diagnostic service is translated into a diagnostic message according to the UDS protocol format by the vehicle-mounted terminal; wherein the UDS protocol is ISO14229, which stands for Unified Diagnostic Services, and is a standardized standard for diagnostic services.

[0055] The diagnostic message is sent to a target control unit.

[0056] The vehicle-mounted terminal is connected to the target control unit via a CAN bus. The CAN bus defines the format and requirements for message transmission between ECUs. ECUs mounted on the CAN bus can communicate with each other and receive messages.

[0057] Step S12, diagnosing the target control unit according to the diagnostic message, forming a response message and sending it to the vehicle terminal;

[0058] Among them, the diagnostic message includes the target diagnostic ID and the diagnostic service. The target control unit receives the diagnostic message, diagnoses the target control unit according to the diagnostic service, and sends a response message to the vehicle terminal. It should be noted that the response message includes the response ID, target condition one, target condition two, and the target resolution file, among which the target diagnostic ID adopts the physical addressing ID defined in the vehicle manufacturer's diagnostic specification, that is, when the remote diagnostic server sends the diagnostic message with the help of the vehicle terminal, the gateway physical request ID is used; the response ID adopts the physical response ID defined in the vehicle manufacturer's diagnostic specification, that is, the target control unit uses the response ID to send the response message to the vehicle terminal.

[0059] Step S13, sending the response message to the remote diagnosis server through the vehicle terminal, and splitting the response message through the remote diagnosis server to form target condition one, target condition two and a target parsing file;

[0060] Among them, target condition one includes the target diagnostic ID of the target control unit, and target condition two includes the target VIN code of the target control unit. In this embodiment, the target parsing file can be a DTC original file.

[0061] Step S14, according to the target condition 1 and the target condition 2, performing the analysis configuration through the remote diagnosis service;

[0062] Specifically, according to the target condition one, an initial parsing subconfiguration is found through a remote diagnosis server, and it is determined whether there are multiple initial parsing subconfigurations;

[0063] If not, determining that the initial parsing subconfiguration is a parsing configuration;

[0064] If so, the initial parsing sub-configuration is screened according to the second target condition, and the initial parsing sub-configuration corresponding to the second target condition is found as the parsing configuration.

[0065] It should be noted that through target conditions one and two, namely the target diagnostic ID and the target VIN code, the parsing configuration of the target parsing file can be accurately found to obtain relevant information such as the cause of the fault and maintenance suggestions. Since cars of the same model with different configurations have the same target control unit and the same target diagnostic ID, this will result in multiple initial parsing sub-configurations being found through the target diagnostic ID when the response message is parsed by the remote diagnostic system, which will cause significant differences in the information parsed from the target parsing file, resulting in the inability to accurately diagnose the fault, resulting in low efficiency in the troubleshooting process and poor user experience. Therefore, target condition two is added to screen multiple initial parsing sub-configurations, find the initial parsing sub-configuration corresponding to target condition two as the parsing configuration, and accurately parse the target parsing file and accurately diagnose the fault.

[0066] The step of screening the initial parsing sub-configuration according to the second target condition and finding the initial parsing sub-configuration corresponding to the second target condition as the parsing configuration specifically includes:

[0067] Obtaining an initial part number in the initial parsing sub-configuration;

[0068] Acquire a target part number of the target control unit according to target condition 2, and match the target part number with the initial part number to screen out an initial parsing sub-configuration matching the target part number;

[0069] Use the filtered initial parsing subconfiguration as the parsing configuration.

[0070] Since cars of the same model with different configurations have different part numbers, the parsing configuration can be filtered out by the target part number. The target part number of the target control unit can be retrieved by the target VIN code to know the car model and configuration. The initial parsing sub-configuration that matches the target part number can be matched with the initial part number of the initial parsing sub-configuration to filter out the initial parsing sub-configuration.

[0071] Among them, the part number includes prefix, infix and suffix. The prefix represents the model code, and the part number prefix of all control units under a model is the same; the infix represents the control unit, and the infix of each control unit under a model is different, and the prefix and infix are unique; the suffix is ​​usually composed of two letters AA, the first A represents the configuration, if A is high configuration, then B is medium configuration, and C is low configuration, the second letter represents the software version, A is the first software version, if an upgrade is performed, it will change from A to B.

[0072] Due to frequent changes in software versions, there is no need to identify the last letter. Therefore, the initial parsing sub-configuration is found according to the target diagnostic ID, and the accurate parsing configuration is screened out through the target VIN code, so that the target parsing file can be accurately parsed. This solves the technical problem that the parsing configuration of cars of the same model with different configurations cannot be accurately configured through the diagnostic ID, and accurate fault diagnosis cannot be achieved.

[0073] Step S15, parsing the target parsing file through the parsing configuration to obtain diagnostic data.

[0074] The initial parsing sub-configuration is found according to the target diagnostic ID, and the accurate parsing configuration is screened out through the target VIN code. The target parsing file can be accurately parsed to obtain diagnostic data. This method is simple and only requires the addition of the target VIN code screening to accurately find the parsing configuration, accurately parse the target parsing file, achieve accurate fault diagnosis, and improve the accuracy of remote diagnosis.

[0075] Compared with the prior art, the automobile remote diagnosis method described in this embodiment has the following beneficial effects: specifically, a diagnostic instruction is input to a remote diagnosis server, a diagnostic service is selected according to the diagnostic instruction, and the diagnostic service is sent to the vehicle terminal; the diagnostic service is translated into a diagnostic message by the vehicle terminal, and the diagnostic message is sent to the target control unit; the target control unit is diagnosed according to the diagnostic message, a response message is formed and sent to the vehicle terminal; the response message is sent to the remote diagnosis server by the vehicle terminal, and the response message is split by the remote diagnosis server to form target condition one, target condition two and a target parsing file; according to target condition one and target condition two, a parsing configuration is found by the remote diagnosis server; the target parsing file is parsed by the parsing configuration to obtain diagnostic data, and the parsing configuration of the target parsing file is accurately found by target condition one and target condition two, so that the target parsing file can be accurately parsed to obtain diagnostic data, that is, related information such as fault cause and maintenance suggestion, etc. The method is simple and effectively realizes the accuracy of fault diagnosis, and improves the accuracy of remote diagnosis. This solves the technical problem in the prior art that the parsing configuration of cars of the same model with different configurations cannot be accurately configured through the diagnostic ID, and accurate fault diagnosis cannot be achieved.

[0087] Among them, the diagnostic message includes the target diagnostic ID and the diagnostic service.

It should be noted that the response message includes the response ID, target condition one, target condition two, and the target resolution file, among which the target diagnostic ID adopts the physical addressing ID defined in the vehicle manufacturer's diagnostic specification, that is, when the remote diagnostic server sends the diagnostic message with the help of the vehicle terminal, the gateway physical request ID is used; the response ID adopts the physical response ID defined in the vehicle manufacturer's diagnostic specification, that is, the target control unit uses the response ID to send the response message to the vehicle terminal.
