The invention relates to a method for detecting a blocked state of an ultrasonic sensor () of a motor vehicle (), in which at least one oscillation parameter of the ultrasonic sensor () is recorded and an evaluation device () of the motor vehicle () carries out a detection algorithm which is used to evaluate the at least one oscillation parameter for the purpose of detecting the blocked state. An object () in an area surrounding the motor vehicle () is detected by the evaluation device () on the basis of sensor data from at least one sensor () of the motor vehicle (), in which case, when a distance (D) between the object () and the ultrasonic sensor () falls below a predefined threshold value (G), the detection algorithm is not carried out by the evaluation device () or a blocked state of the ultrasonic sensor (), as detected using the detection algorithm, is ignored by the evaluation device ().

Method for detecting a blocked state of an ultrasonic sensor of a motor vehicle, ultrasonic sensor apparatus and motor vehicle

The invention relates to a method for operating a motor vehicle, in which by at least one ultrasonic sensor, operated in the active operation mode, of an ultrasonic sensor device of the motor vehicle ultrasonic waves are emitted into an environmental region of the motor vehicle, wherein the motor vehicle as hybrid vehicle is equipped with an internal combustion engine (and an electric drive machine and in the active operation mode of the ultrasonic sensor arranged on a rear part of the motor vehicle the motor vehicle at least temporarily is operated by means of the electric drive machine. The invention also relates to a motor vehicle.

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