Abstract

The embodiment of the present invention relates to the technical field of automobile diagnosis, and discloses a bus data analysis method. The method includes: applying to an automobile diagnostic system, wherein the automobile diagnostic system is used to obtain communication data on each automobile bus, and the automobile bus is used for communication between electronic control units of automobiles, the method includes: obtaining a query request from a user, the query request carrying target bus information; collecting communication data of the target bus according to the target bus information; the target bus It is any one or more buses in the automobile bus; analyzes the communication data to obtain an analysis result; generates display content according to the analysis result and a preset display mode; and displays the display content to the user. In the above manner, the embodiment of the present invention achieves the beneficial effect of effectively analyzing the communication quality.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile diagnosis, and in particular, to a bus data analysis method, apparatus, device, automobile diagnosis system, and computer-readable storage medium. Background technique [0002] With more and more electronic control units in the automotive system, the automotive bus connecting the electronic control units becomes more and more complex. The communication quality of the automotive bus is very important to the stability and security of the system operation. Some intermittent faults are often caused by the deterioration of the communication quality of the automobile bus. Analyzing the communication quality and performance of the automobile bus has guiding significance for the troubleshooting of the fault. However, the inventor found that the existing vehicle diagnostic tools do not have the function of analyzing the quality and performance of the bus communication. How to analy...
