Abstract
In a method for determining the position and/or the movement of at least one object in the surroundings of a vehicle with the aid of at least one transmitted acoustic signal, the time behavior of at least one electrical signal of an electroacoustic transducer during the transmission of the acoustic signal and/or during a decay of the electroacoustic transducer following the transmission and/or during the reception of the acoustic signal reflected on the object is analyzed at least during a suitable fraction of a signal period in such a way that changes of the electrical signal of the electroacoustic transducer is detected.
