Fault detection method, device and equipment, and storage medium

Abstract

The invention discloses a fault detection method, device and equipment, and a storage medium. The method includes the following steps: obtaining a fault code set of a to-be-detected vehicle; obtaininga fault case, wherein the fault case records, a mapping relationship between a standard fault code set and a fault accessory set; acquiring a target fault case in the fault case according to the fault code set of the to-be-detected vehicle, wherein the similarity degree between the standard fault code set in the target fault case and the fault code set of the to-be-detected vehicle is highest; and marking the fault accessory set in the target fault case as a fault detection result. The method can make up for limitation of maintenance experience of a maintenance technician, thereby improving the positioning efficiency of a vehicle fault. In addition, the invention also provides the fault detection device and equipment, and the storage medium, and beneficial effects are the same as described above.

Description

technical field [0001] The present application relates to the field of vehicle detection, in particular to a fault detection method, device, equipment and storage medium. Background technique [0002] Existing vehicle diagnostic equipment often adopts a detection method similar to that of the on-board automatic diagnostic system OBD, and reads the operating indicators of vehicle system components through sensors of various electrical monitoring systems, and outputs the operating indicators, and then the maintenance technician reads the equipment output indicators data, and use the maintenance experience of maintenance technicians to locate the actual faulty parts. [0003] With the continuous increase in the number of new car models and new fault types, the accessories in the vehicle are constantly enriched, and the types of fault indicators are also increasing. Since the current diagnostic equipment only outputs fault indicators, and the analysis of faults by maintenance te...
