Abstract

The invention relates to a sensor assembly for recognizing a state of a roadway, including a sensor device, which is adapted to capture an impact of water on a wheel arch lining of a motor vehicle during a travel of the motor vehicle on the roadway, and including a control device for recognizing the state of the roadway based on the impact of the water captured by means of the sensor device, wherein the sensor device includes an ultrasonic sensor, which is adapted to receive an ultrasonic signal and which is additionally adapted to capture the impact of the water on the wheel arch lining.
