Abstract
A device for determining the detection range of a sensor unit for a motor vehicle includes: a memory unit configured to provide a map having map data regarding a landmark and a target detection range, a reflectivity property and/or a radiant intensity respectively associated with the landmark; a sensor unit configured to detect the landmark in surroundings with an actual detection range and/or to measure a received signal intensity for the landmark; and a computing unit configured to determine a detection range of the sensor unit based on the target detection range and the actual detection range and/or based on a comparison of the received signal intensity with a calculated signal intensity derived from the reflectivity property and/or the radiant intensity associated with the landmark.
