Abstract
Proposed is an ultrasonic sensor system () for a motor vehicle (), comprising an ultrasonic sensor () and a test control device (). The ultrasonic sensor () comprises an electroacoustic converter arrangement () for generating and detecting ultrasonic waves and an electric test device (), which is designed to output an electric test signal to the electroacoustic converter arrangement () and to detect an electric response signal of the electroacoustic converter arrangement () to the electric test signal. The test control device () is designed to detect a characteristic variable of the electric response signal at a plurality of measurement points () by means of the electric test device () by varying a frequency and an amplitude of the electric test signal.
