A method of operating an ultrasonic sensor for a motor vehicle with suppression of disturbances in a second receiving path, ultrasonic sensor and driver assistance system

摘要

The invention relates to a method for operating an ultrasound sensor (4) for a motor vehicle (1), wherein the ultrasound sensor (4) is designed to receive a first ultrasound signal and a second ultrasound signal, in which case the receiver is received in an ambient region (9) of the motor vehicle (1) a raw signal is determined, a first correlation signal (K1) which describes a correlation of the raw signal with a first reference signal for the first ultrasonic signal, and a second correlation signal (K2), which correlates the raw signal with a second reference signal describes for the second ultrasonic signal to be determined, based on an amplitude (A) of the first correlation signal (K1) a second correction signal (Q2) for correcting the second correlation signal (K2) is determined and based on an amplitude (A) of the second correlation signal (K2 ) a first correction signal (Q1) to the corr igieren the first correlation signal (K1) is determined.
