[0092] In this embodiment, Figure 3 The various vehicle controllers shown in the figure exchange signals via the vehicle communication bus. The signals exchanged between the controllers are raw values, which need to be parsed into physical values ​​according to a specific protocol. Different vehicle communication buses have corresponding parsing files. For example, the commonly used CAN bus can use a DBC file as a parsing file. The parsing file mainly contains the signal name, data frame identifier, vehicle communication network channel number where the signal is located, signal start bit in the data field, signal bit length, signal parsing method, signal unit, etc. The parsing file is editable.

The protocols specify the format of the data frames. The identifiers in the data frames are used to distinguish between different data frames, and the data fields in the data frames contain the actual signals to be transmitted.

[0105] According to the data content of the configuration file, obtain the channel number of the vehicle communication network where the data frame required to troubleshoot this fault is located;

[0106] Construct a request message containing a channel number and a list of data frame identifiers;

[0107] According to the communication protocol of the corresponding on-board controller, the request message including the channel number and the data frame identifier list is converted to obtain the collection request of the corresponding on-board controller.

[0108] Optionally, in step 8, generating a data upload request for the vehicle controller based on the required data frame identifier list and the required timestamp set includes:

[0109] Obtain the data frame identifier list, required timestamp set, and vehicle communication network channel number of the data frame required for troubleshooting the fault according to the configuration file;

[0110] Construct a request message containing the channel number, a list of data frame identifiers required to troubleshoot the fault, and a required timestamp set;

[0111] According to the communication protocol of the corresponding vehicle controller, the request message containing the channel number, the data frame identifier list required for troubleshooting this fault and the required timestamp set is converted to obtain the data upload request of the corresponding vehicle controller.

[0112] Optionally, the method further includes: the vehicle controller performs bus communication with other devices in the vehicle according to the issued acquisition request to obtain the original data of the data frame associated with the acquisition request;

[0113] The original data of each data frame is stored in the order of timestamp to obtain the information set of each device in the vehicle;

[0114] The on-board controller filters the information sets of each device in the vehicle according to the data upload request issued, obtains the original data of the data frame associated with the data upload request, and packages the original data of the data frame associated with the data upload request and uploads it to the remote communication platform server.

[0115] Optionally, the fault analysis table is stored in a remote communication platform server;

[0116] The fault analysis table consists of a fault code, a data frame type required for fault troubleshooting, a judgment threshold related to the data required for fault troubleshooting, and description information related to the fault.

[0118] Editing the generated parsing file to increase or decrease the data frame identifier in the parsing file without iterating the remote communication platform program and the vehicle controller program;

[0119] Edit the generated configuration file to modify the vehicle signal associated with the fault code.

[0120] Example 2

[0121] This embodiment provides another vehicle remote diagnosis method, such as Figure 4 When a vehicle failure occurs and a repair report is submitted, a service worker or other automated program enters the vehicle failure repair information into the remote communication platform according to the repair content. The remote communication platform processor then performs the following steps:

[0122] Obtain vehicle fault repair information;

[0123] Generate a collection file and signal configuration format instructions based on the vehicle fault repair information, and first send the collection file to the associated vehicle controller;

[0124] When the onboard controller feeds back the response of the acquisition file, the signal configuration format instruction is sent to the associated onboard controller again;

[0126] Compare the physical values ​​of each signal according to the preset fault analysis table to obtain remote fault diagnosis results;

[0127] The working steps of the on-board controller include:

[0128] Receive the collected files sent by the remote communication platform and provide real-time feedback on the receiving progress to the remote communication platform;

[0129] After sending a response indicating that the acquisition file has been received to the remote communication platform, the signal configuration format instruction sent by the remote communication platform is received;

[0130] Read the acquisition file to obtain the signal analysis table;

The on-board controller can use this file to parse the collected vehicle signal raw data into the actual content of the signal.

[0137] In summary, the remote communication platform of the present invention automatically obtains parsed and configured files from vehicle fault repair information, thereby realizing a series of automated data transfer processes between the remote communication platform and the vehicle, including data collection, data screening, data upload, information extraction, fault diagnosis, and vehicle troubleshooting, thereby reducing the storage space requirements of the remote communication platform and the on-board controller. The required vehicle information is obtained by parsing the file and sent to the on-board controller. The on-board controller collects and stores data according to the data frame identifier list to be collected. The collected and stored data are all necessary data for troubleshooting.

[0138] The data frame identifiers required for troubleshooting vehicle faults are obtained through a configuration file and sent to the onboard controller. The onboard controller only needs to upload the necessary data, preventing unnecessary data from occupying transmission channels and database storage space, and quickly obtaining diagnostic results. The parsing file of the present invention is editable.
