Device and method for detecting vehicle tyre camber angle and toe-in angle

Abstract

The invention provides a device and method for detecting the vehicle tyre camber angle and toe-in angle. The device for detecting the vehicle tyre camber angle and toe-in angle comprises detection platforms symmetrically arranged at the outer sides of two traffic lanes respectively, wherein the surface, facing to the traffic lane, of each detection platform is provided with a structured light emitter and cameras arranged at the two sides of the structured light emitter and for collecting images of the structured light emitter irradiated on a vehicle wheel; and a processing unit which receives the images collected by the cameras on the two detection platforms. The beneficial effects of the detection device are that the device adopts a split-type design, and thus the size of the device is greatly reduced; the device adopts the fixed-type installation, and thus after installation, the cameras cannot be moved; the device can be used repeatedly for a long time with only one-time calibration during installation, thereby improving detection precision and reducing system maintenance; and the vehicle is detected in a manner of non-contact pass-type detection, and conventional accessory devices of reflector panels and the like no longer need to be arranged on the vehicle, thereby greatly improving the detection speed and reducing manual labor intensity.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a device and method for detecting the camber angle and toe angle of vehicle tires. Background technique [0002] At present, the four-wheel alignment detection device is usually used to detect the caster angle, the kingpin inclination angle, the front wheel camber angle, the front wheel toe-in angle, the wheel camber angle and the rear wheel toe-in angle to ensure the quality of the car leaving the factory or maintenance. . However, because the four-wheel alignment detection device is inconvenient to install and cannot be calibrated in time during use, the quality of vehicle inspection is greatly affected. Therefore need a kind of detection method simple in structure, save space, easy to install and use to detect and detect vehicle tire camber angle and toe angle, be applicable to the four-wheel alignment in automobile manufacturing and maintenance.
