ABSTRACT:
A method for functionally testing an ultrasonic sensor on a motor vehicle in which, in a test operating mode, an ultrasonic signal is emitted whose magnitude is large enough that under conventional conditions this ultrasonic signal is reflected by a ground surface in front of the vehicle and is received again. In this way, it can easily be determined that the ultrasonic sensor is functioning properly.
