Abstract:
1. A electronic automobile anti-theft apparatus comprising: a locking means for selectively locking a steering mechanism or a driving mechanism of an automobile; an actuator for operating the locking means; a control unit for controlling the operation of the actuator, wherein the control unit generates a control signal for controlling the operation of the actuator; a detector for detecting the position of a shift lever for a transmission shift device of the automobile and generating a detection signal when the shift lever is located at a parking position; a switching device connected to one of the actuator and the control unit to permit power to be supplied to the one of the actuator and the control unit in response to the detection signal; a lock position detector connected to one of the actuator and the control unit to detect whether the locking means has been released and to permit power to be supplied from a power supply to one of the actuator and the control unit until the locking means is released; and a switching circuit connected to the actuator and the switching device to switch routes for supplying power to the actuator in accordance with the control signal, wherein the switching device and the lock position detector arc connected between the power supply and the switching circuit.
