摘要

In a method for functional testing of an ultrasonic sensor on a motor vehicle, the ultrasonic sensor is controlled in such a way that it emits an ultrasonic signal having a frequency of a secondary mode of the ultrasonic sensor, the ultrasonic signal is reflected by a surface in the region around the vehicle, and at least one transmission path or one transmitting unit of the ultrasonic sensor is classified as functional if the reflected signal is received by the ultrasonic sensor itself or by another ultrasonic sensor on the motor vehicle.
