Automobile wheel alignment judging device and judging method thereof

Abstract

The invention relates to an automobile wheel positioning judgment device and a judgment method thereof. The automobile wheel positioning judgment device comprises a wheel angle sensor, a steering wheel angle sensor, a central processing unit and a prompting unit, wherein the wheel angle sensor is mounted on an automobile front axle wheel steering column; the steering wheel angle sensor is mounted on an automobile steering wheel steering shaft; output ends of the wheel angle sensor and the steering wheel angle sensor and the output end of a vehicle speed sensor of an automobile are connected with an input end of the central processing unit respectively; the output end of the central processing unit is connected with the input end of the prompting unit. The judgment method comprises the following steps: receiving values sent by the steering wheel angle sensor and the wheel angle sensor by the central processing unit and analyzing and judging with a vehicle speed considered; once if the two angle values are not matched, starting the promoting unit to alarm. According to the automobile wheel positioning judgment device, a driver can obtain abnormal conditions of steering wheel positioning in time and can conveniently repair and maintain the automobile wheel positioning judgment device in time; the driving safety is improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile wheel alignment judging device and a judging method thereof. Background technique [0002] The rotation of the steering wheel of the front axle of the car is controlled by the rotation of the steering wheel. For ordinary cars, the steering wheel angle is generally within 900 degrees, and the wheel angle range is about 90 degrees. The ratio of the two is about 10:1. After the car has been running for a period of time, especially after there has been a collision or tire replacement, the steering wheel of the front axle of the car will generally have a certain degree of angle deviation, that is, the ratio of the steering wheel angle to the steering wheel angle has exceeded 10:1. However, there is no relevant real-time monitoring system on the car at present, and the driver cannot know whether the wheel steering is normal in time. Whether the steering wheel align...
