Abstract (en)
[origin: WO2020064153A1] The invention relates to a method for operating an ultrasonic sensor (4) of a vehicle (1), in which a sound transducer element (11) of the ultrasonic sensor (4) is excited by a predetermined excitation signal, wherein the excitation signal has a predetermined current strength, a test voltage (U) is measured at the sound transducer element (11) as a consequence of the excitation signal and diagnostics are carried out on the ultrasonic sensor (4) on the basis of the test voltage (U), wherein the ultrasonic sensor (4) is excited by the excitation signal during a measuring operation to emit an ultrasonic signal, the test voltage (U) is measured during the transmission, reduced diagnostics are carried out on the basis of the test voltage (U), wherein the ultrasonic sensor (4) either continues to be operated during the measuring operation or is operated during a diagnostic operation for a complete diagnosis, depending on a result of the reduced diagnostics.
