Method for operating ultrasonic sensor of vehicle along with reduced diagnosis in measurement mode of ultrasonic sensor and ultrasonic sensor device

摘要

InventionA method of operating an ultrasonic sensor (4) of a vehicleThe acoustic transducer element (11) of the ultrasonic sensor (4) is excited by a predetermined excitation signal in the vehicle (1);The excitation signal has a predetermined current amplitudeThe electrical test voltage (U) at the acoustic transducer element (11) due to the excitation signal is measured;The diagnosis of the ultrasonic sensor (4) is based on the test voltage (U) andUltrasonic sensorThe excitation signal is excited by the excitation signal in the measurement mode for transmission of the ultrasonic signalElectrical test voltage (U) is measured during transmission.A reduced diagnosis is performed based on the electrical test voltage (U)Ultrasonic sensorAccording to the results of reduced diagnosisKeep running in the measurement modeIs it operated in diagnostic mode for complete diagnosis?Related to the method.
