초록 ▼

A system for measuring angular relationships of wheels of a vehicle includes a radiation source mounted with respect to a first wheel for providing a radiation signal, an image detector having an active array of pixels mounted with respect to a second wheel for receiving an image from the radiation source and for producing an output in response to the radiation signal, and a radiation detector disposed in the path of the radiation from the radiation source for detecting the presence of the radiation signal. A controller is responsive to the presence of the radiation signal to activate the image detector to receive the image from the radiation source and determine an alignment angle of a wheel of the vehicle from the output of the image detector. A mask is mounted between the radiation source and the detector for defining an image of the radiation source upon the detector, the mask preferably having at least three slits therein the system also uses radiation signals and the active pixel array detector to electronically determine wheel base and/or track width and corrects alignment characteristic values for errors which are affected by wheelbase. The system also uses such radiation signals and detectors to electronically determine ride height and/or wheel offset distances.

An improved vehicle wheel alignment system comprising: a first sensor unit adapted to be removably mounted to a front wheel of a vehicle whose alignment is to be tested; a second sensor unit adapted to be removably mounted to a rear wheel of the vehicle under test such that the front wheel and the rear wheel are disposed on the same side of the vehicle; said first and second sensor units obtaining wheel alignment data for their respective wheels; determining means for determining wheel alignment characteristics of said front and rear wheels from the wheel alignment data from the first and second sensor units; at least one of the first and second sensor units having an active pixel array detector, said active pixel array detector providing the wheel alignment data for said sensor unit; said first and second sensor units including means, including at least one radiation source, for projecting at least two spatially separated images upon the active pixel array detector, the spatial separation of said two images being a function of the wheelbase of the vehicle under test; said determining means being responsive to the active pixel array detector to determine the wheelbase of the vehicle under test from the spatial separation of the images on the active pixel array detector.
