Abstract:
The invention relates to a method for operating an ultrasonic sensor apparatus (3) having a multiplicity of ultrasonic sensors (5, 6, 7) arranged in the rear region (4) of a motor vehicle (1) in which the ultrasonic sensor apparatus (3) is used to perform detection of an object (11) in the surroundings of the motor vehicle (1), wherein a first ultrasonic sensor (6), in an object detection mode for detecting an object (11) that is different from a trailer apparatus (10) arranged in the rear region (4), is operated only for the purpose of receiving echo signals from transmission signals transmitted by at least one other ultrasonic sensor (5, 7), and the sending of transmission signals from this first ultrasonic sensor (6) is prevented. The invention also relates to a driver assistance device (2) and a motor vehicle (1).
