The invention provides a tire pattern depth measuring method based on a laser distance measuring sensor, and the method comprises the following steps: driving a tire between a first roller and a second roller, and enabling a servo mechanism to drive the laser distance measuring sensor to approach the tire until a tread and a pattern groove reach a measuring range; enabling the servo mechanism to drive the laser distance measuring sensor to move and scan in the axial direction of the tire to obtain the distance between the laser distance measuring sensor and the tread and the pattern groove bottom so as to obtain the pattern depth detection value of the tire; obtaining a correction coefficient according to the two distance values, the radius of the roller, the position coordinates of the laser distance measuring sensor, the included angle between the detection light of the laser distance measuring sensor and the horizontal line and the known quantity of the axis coordinate positions ofthe first roller and the second roller; and correcting the pattern depth detection value through the correction coefficient to obtain a pattern depth actual value of the tire. The tire pattern depth measuring method based on the laser distance measuring sensor is good in measuring precision and high in detecting efficiency.
Description
technical field [0001] The invention belongs to the technical field of motor vehicle detection, and more specifically relates to a tire tread depth measurement method based on a laser ranging sensor. Background technique [0002] The function of the pattern of the car tire is to increase the friction between the tread and the road surface, remove water to prevent the wheels from slipping, the tire pattern improves the ground elasticity of the tread, and the tangential force between the tread and the road surface (such as driving force, braking force) Under the action of the tread and lateral force, the pattern can produce a large elastic deformation, and the greater the elastic deformation, the friction force of the contact surface will increase accordingly, thereby inhibiting the slipping tendency between the tread and the road surface, making the relevant vehicle performance (such as Power performance, braking performance, steering maneuverability and driving safety) are r...
