Problems solved by technology

In the existing vehicle diagnosis system, only when a confirmed vehicle failure occurs, the on-board terminal will send the predefined vehicle failure information to the diagnosis server. or defects, the vehicle-mounted terminal will not send any information to the diagnostic server, which will cause the diagnostic server to fail to detect software problems or undefined hardware problems in the running of the car or lose information when undefined faults and defects occur

Embodiment 1

[0025] figure 1 It is a flow chart of the method for collecting automobile logs provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of collecting automobile logs, and the method can be executed by a vehicle-mounted terminal and a log collection server, such as figure 1 Shown, the collection method of automobile log can comprise the steps:

[0026] S110. The vehicle-mounted terminal obtains log codes corresponding to each vehicle log from each in-vehicle microprocessor.

[0027] In this embodiment, when a vehicle log is generated by the microprocessor in the vehicle, the vehicle log is encoded to form a log code and stored in the non-initialized memory of the microprocessor itself. The corresponding log codes of each automobile log are obtained in the internal microprocessor. Exemplarily, the log code includes at least: a log header and a log ID. The size of the log header is 1 byte, the log ID is 2 bytes, and a log code is at le...

Embodiment 2

[0038] figure 2It is a flow chart of the method for collecting automobile logs provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments, such as figure 2 As shown, the collection method of the optimized car log can include the following steps:

[0039] S210. The vehicle-mounted terminal detects the working state of the controller area network CAN bus between the vehicle-mounted terminal and each microprocessor in the vehicle; wherein, the working state includes: running state and dormant state.

[0040] In this embodiment, the vehicle-mounted terminal detects whether the controller area network CAN bus between the vehicle-mounted terminal and each microprocessor in the vehicle is working in the running state or in the dormant state. The dormant state means that the CAN bus enters a mode with very small power consumption after the car is turned off for a period of time, and no information transmission is ...

Embodiment 3

[0054] image 3 It is a schematic structural diagram of the vehicle-mounted terminal provided by Embodiment 3 of the present invention. This embodiment can be applied to the situation of collecting automobile logs, such as image 3 As shown, the vehicle-mounted terminal may include the following structure: an acquisition module 310 and a sending module 320; wherein,

[0055] The acquiring module 310 is configured to acquire log codes corresponding to each car log in each in-vehicle microprocessor.

[0056] The sending module 320 is configured to send the log code corresponding to each automobile log to the log collection server.

[0057] Further, the acquisition module 310 includes: a detection unit and an acquisition unit; wherein,

[0058] The detection unit is used to detect the working state of the controller area network CAN bus between the vehicle-mounted terminal and each in-vehicle microprocessor; wherein, the working state includes: running state and dormant state. ...

Abstract

The invention discloses an automobile log collection method, a vehicle-mounted terminal and a log collection server. The method comprises the following steps: the vehicle-mounted terminal obtains a log code corresponding to each automobile log in each onboard microprocessor; the vehicle-mounted terminal sends the log code corresponding to each automobile log to the log collection server; and the log collection server collects the log code corresponding to each automobile log, and restores each automobile log according to the log code corresponding to each automobile log. According to the technical scheme, the vehicle-mounted terminal sends the obtained log code to the log collection server, and the log collection server can collect the automobile log of each automobile part, so that the log collection server can find the software problems or undefined hardware problems in the automobile operation process in time; and when an automobile has a problem, the problem can be analyzed based on the log saved before or at present to avoid the trouble of having to go to the site to disassemble the parts one by one to troubleshoot the problem.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Internet of Vehicles, and in particular, to a method for collecting automobile logs, a vehicle-mounted terminal, and a log collection server. Background technique [0002] With the rapid development of the Internet of Things technology and wireless communication technology, the Internet of Vehicles, as one of the application demonstration fields of the Internet of Things, has attracted the attention of all parties. As an important branch of the Internet of Vehicles, automotive remote diagnosis has become a hot technology of common concern to many automotive professionals. [0003] Car remote diagnosis means that when the car is started, the fault information of the car is obtained, and the car log of the fault type is uploaded to the car diagnosis system. The car diagnosis system rechecks the fault information without disturbing the car owner. After the fault is confirmed, it will a...
