Abstract: A method for detecting an object within a surrounding area of a vehicle, includes: repeatedly transmitting wave pulses into the surrounding area; repeatedly receiving wave pulses, which correspond to the transmitted wave pulses reflected by the objects; detecting the object with the aid of a signal representation of the received wave pulses, and ascertaining at least one signal characteristic of a first received wave pulse. The detecting of the object includes: comparing the curve in the form of the signal characteristic of the first received wave pulse to the curve of a further received wave pulse, which was received after the first received wave pulse, location information of the object being corrected in light of the comparison.

Abstract: An ultrasonic sensor has: a diaphragm that includes at least two partial regions for emitting and/or receiving ultrasonic signals, the two partial regions possessing different resonance characteristics; and at least one electromechanical transducer coupled to the diaphragm, to which transducer a control signal having at least two different control signal frequencies is applied. In this context, a first control signal frequency is in the range of a resonant frequency of a first partial region of the diaphragm, and a second control signal frequency is in the range of a resonant frequency of a second partial region of the diaphragm. Alternatively, two electromechanical transducers are used, which are coupled to a diaphragm and have different resonance characteristics.
