Abstract
A device for the detection of an at least partial flooding of a motor vehicle. The device includes an ultrasonic sensor that is designed to transmit and to receive ultrasonic signals. The device also includes an electronic recognition device, which can recognize an at least partial flooding of the motor vehicle on the basis of an ultrasonic signal received by the ultrasonic sensor. The recognition device is designed to determine the amplitudes of ultrasonic signals received within a defined time window, and to compare the amplitudes to a defined threshold value. The recognition device is designed to detect a flooding of the ultrasonic sensor as a function of the result of the comparison.
