Abstract
The disclosure relates to a method and an associated device for detecting uneven surfaces in vehicle environments. The method comprises emitting a first ultrasonic pulse or first ultrasonic burst and emitting a second ultrasonic pulse or second ultrasonic burst, and receiving a first reflection signal of the first ultrasonic pulse or a first reflection signal of the first ultrasonic burst and receiving a second reflection signal of the second ultrasonic pulse or a second reflection signal of the second ultrasonic burst. In the further course of the method, a comparison is made of the first reflection signal with the second reflection signal, and the presence of a surface unevenness in the vehicle's environment, or the presence of a surface curvature in the vehicle's environment, is determined.
