Abstract

The invention discloses a vehicle deviation degree detection and analysis method and system and a storage medium. The method comprises steps of controlling a target vehicle to run linearly at a constant speed according to a preset vehicle speed, and obtaining a linear driving track of the target vehicle when the target vehicle runs linearly at a constant speed for a first test time length; controlling the target vehicle to freely run at a constant speed according to a preset vehicle speed when the steering wheel is in a free state, and acquiring a free running track of the target vehicle when the target vehicle freely runs at the constant speed for a second test duration; and obtaining the deviation degree information of the target vehicle according to the straight driving track and the free driving track. The method is advantaged in that intelligent control over the steering and speed of the target vehicle is achieved through the controller, interference control of operators is not needed, standard non-uniformity caused by subjective factors in manual operation is avoided, the evaluation result is quantified, and the evaluation result is more reliable.

Description

technical field [0001] The invention relates to the field of automobile performance evaluation, in particular to a detection and analysis method, system and storage medium for vehicle deviation degree. Background technique [0002] The problem of vehicle deviation mainly occurs in the off-line vehicles of various OEMs and after-sales maintenance vehicles. The detection method of each OEM for the off-line vehicle deviation problem is to set up a deviation detection runway. The first 100 meters of the runway is used to correct the direction of the vehicle to keep the vehicle running in a straight line, and the 100 meters behind the runway is used to detect the degree of deviation of the vehicle. , After the driver corrected the direction in the first 100 meters, he let go of the test vehicle in the last 100 meters and deviated. [0003] At present, for the detection of deviation problems of after-sales maintenance vehicles, it can only be subjectively evaluated by the driver ...
