<p>The rig (P) has a roller (L) driven by a drive (A) for driving a wheel (R) of a vehicle, where the wheel is fixed at the roller, and a contact-less triangulation sensor unit (S) detecting a position of the wheel relative to the roller. The sensor unit detects a horizontal drifting of the wheel from a preset reference position in a horizontal direction, and a control unit (T) controls the rig and evaluates signals of the sensor unit.</p> |
