Abstract

The invention discloses an automobile fault diagnosis method and equipment, a storage medium and a device. The method comprises the following steps: detecting the state of a communication message at preset time intervals, and judging whether a communication fault exists or not according to the state of the communication message: if the communication fault exists, obtaining a fault index value, searching a fault code and a timestamp corresponding to the fault index value in a preset storage area, and sending the fault code and the timestamp to a preset client, so that the preset client performsautomobile fault diagnosis according to the fault code and the timestamp. According to the invention, the fault index value is obtained during the communication fault, and the fault code and the timestamp are searched according to the fault index value, so the automobile fault diagnosis is more reasonable, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile fault diagnosis method, equipment, storage medium and device. Background technique [0002] At present, the traditional communication fault detection process is as follows: the underlying protocol unit of the Electronic Control Unit (ECU) obtains communication messages from the Controller Area Network (CAN) bus, and the upper-layer application module of the ECU performs a check on the received messages. The periodical monitoring of the message is carried out. When the loss of the communication message is detected, the timer module is started to count. Within the specified time, it is generally 10 times the message sending cycle. When a frame message is 50ms, the defined time The threshold is 500ms. If no valid message is received continuously, the fault code will be recorded to the storage unit. In the prior art, the time point of locating the fault can...
