Abstract: The invention relates to an operating method and a vehicle cleaning system comprising at least one treatment device, a control unit and a device for the optical detection of a vehicle. According to said method a vehicle entering or situated in the system is optically detected by a camera system inside the vehicle cleaning system. The data are entered into the control unit so as to control or regulate one or more system functions. Said data can be used in particular to control a drive-in aid or the treatment device which comprises washing brushes, high-pressure nozzles, dryer nozzles, etc.

Abstract: The invention relates to an operating method and a vehicle treatment installation (1) comprising at least one portal (3) and a signaling device (7) for guiding the vehicle operator. The vehicle treatment installation (1) has a drive-in aid (19) which transmits to the vehicle operator optical direction and correcting instructions. The drive-in aid can, for example, generate optically visible guide lines (34) aligned along the direction of travel. It can also comprise a measurement device (12, 13) in the form of a sensor system or an optical detection system with cameras (24, 25), which detect and evaluate the position and alignment of the vehicle (2) when it is driven in and via a signaling device (7) transmit to the vehicle operator corresponding instructions (10) relative to the direction of travel.
