Vehicle diagnostic method, diagnostic cartridge and computer-readable storage medium

Abstract

The invention belongs to the technical field of vehicle diagnosis, and particularly relates to a vehicle diagnosis method, a diagnosis kit and a computer readable storage medium. The method comprisesthe steps of acquiring a diagnosis instruction sent by an upper computer, and analyzing the diagnosis instruction to obtain an interface function type called by the diagnosis instruction; judging whether the called interface function type is consistent with interface function types supported by the diagnosis kit or not; if the called interface function type is not consistent with interface function types supported by the diagnosis kit, converting the diagnosis instruction into a diagnosis instruction containing an interface function type consistent with interface function types supported by the diagnosis kit; and enabling the diagnosis kit to be compatible with diagnosis instructions for calling different interface function types. That means, the diagnosis kit is simultaneously compatiblewith upper computers developed based on different interface functions. Therefore, the good universality is realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle diagnosis, and in particular relates to a vehicle diagnosis method, a diagnosis box and a computer-readable storage medium. Background technique [0002] In the prior art, the upper computer communicates with the vehicle through a diagnostic box to obtain diagnostic data of the vehicle, which includes fault information of the vehicle, so that vehicle maintenance personnel can accurately analyze the faults of the vehicle based on the fault information. [0003] However, in the prior art, the upper computers produced by different manufacturers are equipped with diagnostic software developed based on different function interfaces, and a diagnostic box corresponding to the diagnostic software is required to diagnose vehicle faults. For example, when the diagnostic software of a car factory is based on J2534 The diagnostic software developed by the interface function needs to use a diagnostic box that ...
