The invention relates to a sensor system () for a motor vehicle, comprising a sensor housing and an active or passive sensor () arranged therein and held on a movable sensor holder (), having a sensor technology based on radiation detection and a measurement apparatus assigned to the sensor () and a control apparatus, coupled to said measurement apparatus, for the sensor holder (), wherein the sensor housing has a cover () that is signal-transmissive for the sensor () on its side located in the detection direction of the sensor (), and wherein the detection range () of the sensor () in the region of the signal-transmissive cover () has a lower extent than the signal-transmissive cover (), wherein the sensor system () is characterized in that the measurement apparatus is designed such that it is suitable for checking, in the detection range of the sensor (), whether and in which section the signal-transmissive cover () has a region with reduced signal transmissivity (), wherein the measurement apparatus interacts with the control apparatus in such a way that the control apparatus is able to change the position of the sensor () in such a way that the region with reduced signal transmissivity () lies outside the detection range () of the sensor (). The invention furthermore relates to a method for operating such a sensor system () and to a motor vehicle that is equipped with such a sensor system ().

The invention relates to a sensor system () for a vehicle, in particular a motor vehicle, comprising a sensor housing and an active or passive sensor () arranged therein, having a sensor technology based on radiation detection and a measurement apparatus assigned to the sensor (), wherein the sensor housing has a cover () that is signal-transmissive for the sensor () on its side located in the detection direction of the sensor (), and wherein the detection range of the sensor () in the region of the signal-transmissive cover () has a lower extent than the signal-transmissive cover (), wherein the sensor system () is characterized in that the sensor () is assigned a movable deflection apparatus (), coupled to a control apparatus, for deflecting the radiation of the sensor (), wherein the measurement apparatus is designed such that it is suitable for checking, in the detection range of the sensor (), whether and in which section the signal-transmissive cover () has a region with reduced signal transmissivity (), wherein the measurement apparatus interacts with the control apparatus of the deflection apparatus () in such a way that the control apparatus is able to change the position of the deflection apparatus () in such a way that the region with reduced signal transmissivity () lies outside the detection range of the sensor (). The invention furthermore relates to a method for operating such a sensor system () and to a motor vehicle that is equipped with such a sensor system ().

Surroundings sensor with a movable deflection apparatus for motor vehicles

The invention relates to a vehicle utilizing a LiDAR sensor system for driver assistance systems. A composition consisting of a thermoplastic material based on polycarbonate is used here for forming the substrate layer of a cover for the sensor with respect to the surroundings. The cover has a polysiloxane-based topcoat layer comprising a combination of organically modified silane with a silica sol, the silicon dioxide having a d90 particle size of less than 0.50 micron, in order to achieve high abrasion resistance and weathering stability.
