Abstract

The invention provides a vehicle diagnosis method, a device and equipment. The method comprises the steps of fault symptom information of a vehicle, determining a target fault problem according to thefault symptom information of the vehicle, and determining a solution corresponding to the target fault problem. According to the method, the vehicle is not required to be detected completely; an acquisition scope of fault codes and data flows is reduced; the diagnosis efficiency is high; the vehicle can be directly diagnosed according to the fault symptom information; a diagnosis process is simplified; a diagnosis result is more reliable and complete; and the method is wider in applicability.

Description

technical field [0001] The invention relates to the technical field of automobile fault diagnosis, in particular to a vehicle diagnosis method, device and equipment. Background technique [0002] With the development of vehicle diagnostic technology, when performing vehicle fault diagnosis, various diagnostic parameters of the vehicle are often detected, tested, and analyzed with the help of professional diagnostic instruments to determine the cause of the vehicle's fault. Then select the corresponding solution to repair the vehicle according to the determined cause of the failure. [0003] At present, the diagnostic process of vehicle diagnostic instruments on the market is generally: first determine the vehicle model, then perform operations such as fault code scanning and data stream reading; finally determine the fault problem by manually analyzing the fault codes and data streams output by the diagnostic instrument . [0004] However, the existing vehicle diagnostic i...
