Abstract (en)
[origin: WO2015039805A1] The invention relates to a method for operating an ultrasonic sensor of a motor vehicle (1) when emitting a transmission signal in an area surrounding the motor vehicle (1), characterized by estimating a Doppler shift (fD) which is presumably experienced by the transmission signal in the surrounding area, by stipulating a transmission frequency (fS) for the transmission signal such that a reception frequency (fE) of a reception signal, which corresponds to the transmission frequency (fS) shifted by the estimated Doppler shift (fD), is in a predefined range of frequency values, in particular corresponds to a basic transmission frequency (fB), and by emitting the transmission signal at the stipulated transmission frequency (fS).
