Abstract: The invention relates to a method for detecting a blocked state of an ultrasonic sensor (3) of a motor vehicle (1), in which at least one oscillation parameter of the ultrasonic sensor (3) is recorded and an evaluation device (4) of the motor vehicle (1) 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 (9) in an area surrounding the motor vehicle (1) is detected by the evaluation device (4) on the basis of sensor data from at least one sensor (3, 8) of the motor vehicle (1), in which case, when a distance (D) between the object (9) and the ultrasonic sensor (3) falls below a predefined threshold value (G), the detection algorithm is not carried out by the evaluation device (4) or a blocked state of the ultrasonic sensor (3), as detected using the detection algorithm, is ignored by the evaluation device (4).
