SENSOR ARRANGEMENT FOR DETECTING A STATE OF A ROADWAY, COMPRISING AT LEAST TWO ULTRASONIC SENSORS SPACED APART FROM ONE ANOTHER, A DRIVER ASSISTANCE SYSTEM, A MOTOR VEHICLE, AND AN ASSOCIATED METHOD

摘要

The invention relates to a sensor arrangement (3) for detecting a state of a roadway (11), comprising a sensor device (9) designed, when a motor vehicle (1) is travelling on the roadway (11), to sense an impingement of water (12) on a wheel arch lining (13) of the motor vehicle (1), and comprising a control device (7) for detecting the state of the roadway (11) on the basis of the impinging water (12) sensed by said sensor device (9), the sensor device (9) comprising a first and a second ultrasonic sensor (4, 5) each designed to receive an ultrasonic signal and also each designed to sense water (12) impinging onto said wheel arch lining (13), the first and the second ultrasonic sensor (4, 5) being arranged spaced apart from one another on or in said wheel arch lining (13).
