Sensor arrangement for motor vehicle, has optical sensor and optical body that is coupled to vehicle disk over coupling unit, where optical sensor is arranged in vehicle interior behind vehicle disk

摘要

The sensor arrangement has an optical sensor and an optical body (3) that is coupled to a vehicle disk (2) over a coupling unit (4), where the optical sensor is arranged in vehicle interior behind the vehicle disk. The linear thermal expansion coefficient and the output lengths (L,L') of a support element (5) and the coupling unit are aligned on each other in the direction perpendicular to the surface of the vehicle disk.
