Functional verification method of automobile diagnosis instrument

Abstract

The invention discloses a functional verification method of an automobile diagnosis instrument and aims to solve the technical problems of heavy working load, low working efficiency, high error rate and the like due to manual one-to-one comparison of service instructions during functional verification of a diagnosis instrument in the prior art. According to the method, the automobile diagnosis instrument is connected to an electronic control unit through a communication line; a functional verification unit is used for analyzing the service instructions which are sent by the automobile diagnosis instrument in real time, reading corresponding functional specification data of the electronic control unit, and analyzing corresponding service instructions which are defined by a functional specification according to the functional specification data; and the functional verification unit judges whether the service instructions which are sent by the automobile diagnosis instrument are in accordance with the service instructions which are defined in the functional specification by comparison and verifies a diagnosis function of the automobile diagnosis instrument.

Description

technical field [0001] The invention relates to an automobile electronic technology, in particular to a verification method for the function of an automobile diagnostic instrument. Background technique [0002] When a new type of car is about to be mass-produced, the car diagnostic instrument equipped for car after-sales service also needs to be developed. After the vehicle diagnostic instrument is developed, its function needs to be verified. The traditional verification method is to connect the vehicle diagnostic instrument to be verified to the real vehicle for testing, by performing each function of the diagnostic instrument, and then compare the service instructions read from the data analysis equipment with the corresponding service instructions defined in the diagnostic specification One-to-one comparison is used to confirm its correctness. This manual comparison method has a large workload, low work efficiency and high error rate. [0003] The patent document whose...
