The invention discloses a control circuit of automobile reversing radars. The control circuit comprises a triode VT1. A resistor R1 and a resistor R2 which are connected in series are arranged between a base electrode and a collector electrode of the triode VT1. The collector electrode of the triode VT1 is connected with a base electrode of a triode VT2. A collector electrode of the triode VT2 is connected with an inductor L, an ultrasonic transmitting device B and a diode VD1, wherein the ultrasonic transmitting device B and the diode VD1 are connected in series. An emitting electrode of the triode VT2 and an emitting electrode of the triode VT1 are grounded. The control circuit is simple in structure, reasonable in design, capable of being widely applied to the installation and using of the automobile reversing radars and stable in working, and installation and debugging are convenient.
