[0017] Embodiment 1: This embodiment introduces a method for remotely acquiring vehicle data, including: The vehicle communication controller collects data from each channel in the vehicle bus network in real time and saves the data into a file. The file name contains the start time of data collection, and the data is divided into small files according to time for storage; when a serious fault is detected, the vehicle data within 30 seconds before and after the fault is stored separately as a file. In addition to the start time of data collection, the file name also needs to include the corresponding fault code; The operator enters the start time and end time of the required vehicle data on the remote communication platform; The remote communication platform sends a file retrieval instruction to the vehicle communication controller according to the input time information, wherein the instruction includes a start time, a deadline, an upload method and a storage path; The vehicle communication controller retrieves files that meet the time period requirements according to the received file retrieval instruction, and uploads the retrieved files to the server of the remote communication platform; The on-board communication controller feeds back the upload progress to the remote communication platform; The operator downloads the required data files through the remote communication platform.

[0018] The communication method between the vehicle-mounted communication controller and the remote communication platform is not limited to network communication, and files and information packets can also be exchanged through satellite communication.

[0019] The vehicle bus network includes but is not limited to communication buses such as CAN bus and vehicle Ethernet, and different vehicle communication buses select different file formats for data storage.

[0020] The application process of the method for remotely acquiring vehicle data provided in this embodiment specifically involves the following steps: (1) The on-board communication controller saves the data of each channel in the vehicle bus network into files in real time. The file format can be configured according to needs. Because the data is too large, it can be divided into small files according to time for storage. The file name contains the start time of data collection. If a serious fault occurs, the vehicle data 30 seconds before and after the fault can be stored in a separate file to prevent the data before and after the fault from not being in the same file due to time division, resulting in data incoherence. In addition to the start time of data collection, the file name also needs to include the fault code. The on-board communication controller does not actively upload data files to the remote communication platform; (2) The operator enters the start time and end time of the required vehicle data on the remote communication platform; (3) The remote communication platform sends a file retrieval instruction to the vehicle communication controller. The instruction includes the start time, end time, upload method, and storage path; (4) The vehicle communication controller uploads the retrieved files that meet the time period requirements to the remote communication platform, and the data files are stored on the server of the remote communication platform; (5) The on-board communication controller feeds back the upload progress to the remote communication platform; (6) The operator downloads the required data files through the remote communication platform. The specific flow chart is as follows: Figure 2 shown.

[0021] The above method is implemented as follows: (1) The remote communication platform and the vehicle communication controller can establish network communication to achieve the interaction of files and information packets, or can communicate via satellite, without limiting one communication method; (2) The commonly used vehicle communication bus is the CAN bus, and vehicle Ethernet and other communication buses are also being used in vehicle communication. Different vehicle communication buses use different file formats for storage. There is no restriction on one vehicle communication bus.

[0022] (3) The communication mode of the vehicle communication controller is selected based on the communication mode with the remote communication platform and the vehicle communication bus mode.
