Abstract (en)
[origin: WO2014095605A1] The invention relates to a method for the detection of a noise component in an electrical receive signal (S), which is provided by means of an ultrasound sensor (4) of a motor vehicle (1) depending on an ultrasound receive signal received by the ultrasound sensor (4), wherein, after an ultrasound transmit signal has been emitted, a measurement time interval (10) is defined, within which target echoes (11, 14) in the electrical receive signal (S) are evaluated. Within the measurement time interval (10) a determination time interval (12) is defined and it is established depending on an evaluation of the electrical receive signal (S) within the determination time interval (12) whether the receive signal (S) has the noise component or not.
