Abstract:
The invention relates to an ultrasonic measuring system ( 10 ), in particular for measuring distance and/or as a parking aid in vehicles, having an electroacoustic ultrasonic transducer ( 12 ) which has a oscillating element ( 14 ), does not have a voltage converter, can be alternately operated as an ultrasonic transmitter and an ultrasonic receiver and has a signal connection ( 16 ), which is used either as an input or as an output of the ultrasonic transducer ( 12 ), and an earth connection ( 18 ) which is connected to earth, and a control and evaluation unit ( 20 ) for exciting the oscillating element ( 14 ) of the ultrasonic transducer ( 12 ) to emit ultrasonic waves for operating the ultrasonic transducer ( 12 ) during a transmission interval for the purpose of subsequently deactivating the excitation of the oscillating element ( 14 ) and attenuating the latter during a decay phase and for receiving and processing ultrasonic waves in a reception interval. The control and evaluation unit ( 20 ) has a bridge circuit ( 28 ) which is connected to a DC supply voltage ( 80 ) and has controllable switches ( 30  to  40 ) and a charge storage capacitance ( 42 ), the polarity of which can be reversed and which is intended to alternately output a positive and a negative excitation voltage for the signal connection ( 16 ) of the ultrasonic transducer ( 12 ) during the transmission interval. The control and evaluation unit ( 20 ) outputs a voltage pulse of substantially 0 V at the end of the transmission interval for the signal connection ( 16 ) of the ultrasonic transducer ( 12 ).

Claim (Index 3):
The ultrasonic measuring system of  claim 1 , characterized in that the control and evaluation unit comprises a damping inductance which is activated by the control and evaluation unit at the end of the transmission interval at the earliest and can be deactivated during the duration of the decay phase.
