摘要

The motor vehicle (1) has a sensor arrangement (6), which comprises a reflective film (14a) designed as retro-reflector, for deflecting radiation transmitted by a transmission unit to a receiver (13). The reflective film extends along a line, along which the ray beam is disposed with a scanning movement. A control area (3) is arranged between the reflective film on the one hand and the transmission unit as well as the receiver on the other hand. An evaluation unit has a comparing unit for comparing a measuring signal of the receiver with a given set value range signal.
