摘要

System comprises a drive-on plate with a housing (1) and a recess (2) in the middle. A sensor (3) under the recess registers the correct position (i.e. in the middle of the recess) of a wheel of a motor vehicle. The system has two moving bars (4) with spikes, which are coupled to a control device (6). The bars are transported by the control device over and below the surface of the drive-on plate through openings (5) in the plate.
