Claim 13:
14. A steering wheel locking control apparatus comprising:
a power supply switch configured to receive power from a battery when an ignition switch of a vehicle is turned off; and
a switch unit comprising one or more switches connected to a motor, the switch unit being configured to be turned on in response to power being received through the power supply switch, and configured to lock a steering wheel through a closed circuit formed by shorting phases of the motor,
wherein in response to the ignition switch of the vehicle being turned off, the power supply switch is turned on in response to a low signal applied thereto, the low signal being set as a default by a pull-down resistor within an ECU (Electronic Control Unit),
wherein the power supply switch comprises an EFT (Electric Field Transistor) including a gate electrically connected to an MCU (Micro Controller Unit) and a source electrically connected to a line at the battery, and configured to be turned on when the low signal set by the pull-down resistor within the ECU is applied to the gate.
