Problems solved by technology

At present, the data capture of the control system during the operation of the vehicle generally adopts offline data capture. When a fault occurs, the diagnostic instrument is used to read the vehicle fault and freeze the frame data, and the corresponding data cannot be captured according to the type of fault. , can only rely on experience to determine the troubleshooting direction, and cannot quickly analyze and troubleshoot sporadic faults, which is not conducive to troubleshooting

Abstract

The invention discloses a vehicle-mounted diagnosis method and device, electronic equipment and a readable storage medium. The method comprises the following steps: extracting a can network signal when a fault occurs to obtain fault code information; acquiring an internal signal of the controller according to the fault code information; on-board diagnosis is carried out according to the internal signals of the controller, analysis is carried out through the grabbed fault codes, and different types of fault code signals are recorded and uploaded through preset time while the internal signals of the fault codes are determined, so that the troubleshooting efficiency is greatly improved, and especially for accidental faults, the troubleshooting efficiency is greatly improved. The corresponding data can be recorded in real time according to the fault code, the accuracy of fault analysis is improved, the data uploading amount is reduced, and the data quality is ensured.

Description

technical field [0001] The present invention relates to the technical field of vehicle fault diagnosis, and in particular, to an on-board diagnosis method, device, electronic device and readable storage medium. Background technique [0002] With the increasing popularity of domestic vehicles, more and more individuals own vehicles. Therefore, it is very important for car owners to be able to know some basic states of their vehicles locally, such as whether there is a fault in the current vehicle and the location of the fault. At present, the data capture of the control system during the operation of the vehicle generally adopts offline data capture. When a fault occurs, the diagnostic instrument is used to read the fault of the whole vehicle and freeze the frame data. The corresponding data cannot be captured according to the type of fault that occurs. , the troubleshooting direction can only be determined by experience, and it is impossible to quickly analyze and troublesh...
