SENSOR ARRANGEMENT FOR DETECTING A STATE OF A ROADWAY USING AN ULTRASONIC SENSOR, A DRIVER ASSISTANCE SYSTEM, A MOTOR VEHICLE, AND AN ASSOCIATED METHOD

摘要

The invention relates to a sensor arrangement (8) for detecting a state of a roadway (18), comprising a sensor device (10) designed to sense, when a motor vehicle (1) is travelling on the roadway (18), an impingement of water (17) on a wheel arch lining (12) of the motor vehicle (1), and comprising a control device (3) for detecting the state of the roadway (18) on the basis of the impinging water (17) sensed by said sensor device (10), the sensor device (10) comprising an ultrasonic sensor (13) designed to receive an ultrasonic signal and also designed to sense water (17) impinging on said wheel arch lining (12).
