1. An electronic anti-theft apparatus for preventing theft of a vehicle, comprising:
- a locking means for selectively locking a movable component that is operated when the vehicle is being driven;
an actuator for moving the locking means; and
a control circuit including a processor for controlling the actuator, the control circuit including a first power supply line for supplying the actuator with current for moving the locking means, a second power supply line for supplying an electrical component of the vehicle with current to activate the electrical component, a processor supply line for supplying the processor with current, and a switching device for breaking the first power supply line when the vehicle is started;
wherein the processor supply line supplies power to the processor even when the switching device breaks the first power supply line.

Abstract
A steering wheel locking apparatus having high reliability. A steering lock apparatus (1) includes a lock pin (21) engaged with a steering wheel (5), a motor (23) for moving the lock pin, and an ECU (31) for controlling the motor. A switch (61) is arranged in a first power supply line (81) for supplying the motor with current. When supplying an electrical component with current, the switch breaks the first power supply line.

11. An electronic anti-theft apparatus for preventing the theft of a vehicle, comprising:
-
a locking means for selectively locking a movable component that is operated when the vehicle is being driven; an actuator for moving the locking means; a control circuit including a processor for controlling the actuator and a processor supply line for supplying the processor with current, wherein the control circuit supplies the actuator with current to actuate the actuator when the lock member locks the movable component and when releasing the locking; a first power supply line for supplying the actuator with current; and a switching device arranged in the first power supply line for breaking the first power supply line when the locking of the locking means is released and when the vehicle is started; wherein the processor supply line supplies power to the processor even when the switching device breaks the first power supply line. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An electronic anti-theft apparatus for preventing theft of a vehicle, comprising:
-
a locking means for selectively locking a movable component that is operated when the vehicle is being driven; an actuator for moving the locking means; and a control circuit for controlling the actuator, the control circuit comprising; a first power supply line for supplying the actuator with current for moving the movable component; a second power supply line for supplying an electrical component of the vehicle with current to activate the electrical component; a switching device for breaking the first power supply line when the vehicle is started, wherein the switching device is an electrical switching device (41) that is electrically turned ON and OFF; and a drive circuit for driving the electrical switching device, the drive circuit driving the switching device to open the first power supply line when receiving an ignition signal, which is generated when the vehicle is started, a drive permission signal, which is generated by the control circuit, and driving the switching device to close the first power supply line when the vehicle is stopped.
