Detection method and system for wheel alignment and automobile

Abstract

The invention relates to the technical field of automobiles, in particular to a detection method and system for wheel alignment and an automobile. The detection method comprises the following steps that the front end of a wheel to a first ranging point is ranged to obtain first ranging data; the top end of the wheel to a second ranging point is ranged to obtain second ranging data; the first ranging data is compared with a first reference value and the second ranging data is compared with a second reference value; whether the positive and negative toe-in of the wheel are normal or not is judged according to the comparison result of the first ranging data and the first reference value; and whether the positive and negative camber angle of the wheel is normal or not is judged according to the comparison result of the second ranging data and the second reference value. By installing a wheel alignment system in the automobile, the automobile can carry out wheel alignment detection in the running process of the automobile, the detection method and system for wheel alignment aim at solving the problems that an existing automobile requires an owner of the automobile to specially spend time to detect in a repair shop or a 4S shop, and the cost of the existing wheel alignment detection is relatively high.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a detection method and system for wheel alignment and an automobile. Background technique [0002] Due to the current economic development and the improvement of people's living standards, automobiles have already become a part of people's lives, and the problems of automobiles have attracted more and more attention from the public. [0003] After the car has been used for a long time, it is inevitable that the structural parts will age and the parts will be damaged. When the car is driving in a straight line, if the steering wheel does not move and the car runs off, the steering wheel is not straight, the car eats tires, or the steering does not return automatically, etc., the car should be checked for wheel alignment. In the existing technology, the wheel alignment detection needs to go to a special repair shop or 4S shop for detection, and the car owner needs to spend tim...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention proposes a detection method, system and automobile for wheel alignment. By setting the wheel alignment system in the automobile, the wheel alignment detection can be performed by itself during the driving process of the automobile, aiming at solving the problems of existing automobiles. The car owner needs to spend time to go to the repair shop or 4S shop for inspection, and the existing problem of high cost of wheel alignment inspection
