Abstract

The invention relates to a sensor system (200, 300) for a vehicle, in particular a motor vehicle, comprising a sensor housing and an active or passive sensor (102) arranged therein, having a sensor technology based on radiation detection and a measurement apparatus assigned to the sensor (102), wherein the sensor housing has a cover (106) that is signal-transmissive for the sensor (102) on its side located in the detection direction of the sensor (102), and wherein the detection range of the sensor (102) in the region of the signal-transmissive cover (106) has a lower extent than the signal-transmissive cover (106), wherein the sensor system (200, 300) is characterized in that the sensor (102) is assigned a movable deflection apparatus (201), coupled to a control apparatus, for deflecting the radiation of the sensor (102), wherein the measurement apparatus is designed such that it is suitable for checking, in the detection range of the sensor (102), whether and in which section the signal-transmissive cover (106) has a region with reduced signal transmissivity (203, 302), wherein the measurement apparatus interacts with the control apparatus of the deflection apparatus (201) in suc…
