Vehicle diagnosis method, diagnosis terminal and diagnosis box

Abstract

The application embodiment provides a vehicle diagnosis method, a diagnosis terminal and a diagnosis box; the vehicle diagnosis method comprises the following steps: the diagnosis terminal determinesa diagnosis type to which a to-be-diagnosed vehicle belongs according to a received diagnosis command, and further determines a target diagnosis mode of the needed diagnosis box according to the diagnosis type when the to-be-diagnosed vehicle is diagnosed; the diagnosis terminal obtains the present diagnosis mode of the diagnosis box; if said two diagnosis modes are different, the diagnosis terminal sends a diagnosis mode switching command to the diagnosis box so as to remind the diagnosis box to switch the target diagnosis mode, thus enabling the diagnosis terminal to diagnose the to-be-diagnosed vehicle via the diagnosis box working in the target diagnosis mode. The method integrates the diagnosis box that supports new model diagnosis standards and old model diagnosis standards with diagnosis software, thus automatically selecting a proper diagnosis mode according to the to-be-diagnosed vehicle model, preventing frequently switching of the diagnosis modes and diagnosis software of the diagnosis box, and improving the diagnosis efficiency.

Description

technical field [0001] The present application relates to the field of computers, in particular to a vehicle diagnosis method, a diagnosis terminal and a diagnosis box. Background technique [0002] In order to meet the needs of users and adapt to the development and changes of automobiles under the new situation, automobile diagnostic equipment has also been continuously developed. From the past, there was only one diagnostic standard for old models to two diagnostic standards for old cars and the new diagnostic standard of J2534. Before the emergence of new diagnostic standards, the diagnostic equipment had an independent diagnostic box. When diagnosing old models, the diagnostic software controlled the diagnostic box to run the old model diagnostic standards to diagnose the vehicle. With the emergence of new diagnostic standards, if the diagnostic software supports both old models The diagnosis supports the diagnosis of new models, which will cause incompatibility of diag...

Problems solved by technology

In this case, if the vehicle to be diagnosed has multiple old model vehicles and multiple new model vehicles, it is necessary to continuously switch between two diagnostic software and two diagnostic boxes, which not only cumbersome operation, but also reduces the diagnostic time. efficiency
