ABSTRACT:
The process according to the invention controls a drying device for a vehicle wash for a vehicle, a travelling portion of the drying device being movable relative to the vehicle with the aid of a travel motor and a lift motor. The travelling portion carries a drying means and a light barrier whose light beam passes with clearance under the drying means and a device controller operating the travel and lift motors guided on a path which keeps a guaranteed clearance from the contour of the vehicle. At the beginning of the drying process the portion of the drying device in a lowered initial position in front of or behind the vehicle is moved. As a result at least the raising and lowering of that portion is controlled by a gating signal. Before beginning each drying process the sensitivity or response threshold of a gating device for the gating signal and/or a conditioning device adjusting the gating signal is adjusted automatically to a value sufficient to define the release of the light beam. A drying device which performs the process according to the invention is also described.
