Abstract
A sensor system and method for detecting particles, in particular dirt particles or water droplets on a vehicle windscreen, comprising an optical sensor (). The sensor () operates on the basis of light transit time and receives light signals (S) that are emitted by an emitter element and that are at least partially reflected, wherein the emitter element and the sensor () are located and aligned on the exterior of the vehicle, on or in the vicinity of a tailgate, hatchback or trunk lid () of said vehicle () in such a way that particles on the tailgate, hatchback or trunk lid () can be detected by means of the sensor () by sensing the part of light signals (S) emitted by the emitter element that is backscattered by the particles.
