RAIN SENSOR DEVICE FOR DETECTING PRECIPITATION, COMPRISING A COMMUNICATION DEVICE, DRIVER ASSISTANCE SYSTEM, MOTOR VEHICLE, AND METHOD

摘要

The invention relates to a rain sensor device (3) for detecting precipitation on a translucent pane (6) of a motor vehicle (1), comprising at least one transmission element (17) for transmitting electromagnetic radiation, a receiving element (18) for receiving at least one part of the transmitted radiation, a computing device (28) for determining an intensity of the precipitation dependent on the received radiation, and a housing (5) in which the at least one transmission element (17), the receiving element (18), and the computing device (28) are arranged. The rain sensor device (3) has a communication device (8) for identifying radio frequencies in a contactless manner, said communication device additionally being arranged in the housing (5).
