Abstract
A steering wheel locking control apparatus may include: 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 connected to a motor, turned on when power is received through the power supply switch, and configured to lock a steering wheel through a closed circuit formed by shorting phases of the motor.
Claims18
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;
- 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;
- and
- a protection circuit configured to control the one or more switches of the switch unit not to operate, regardless of the operation of the power supply switch, in response to a control signal according to turn-on of the ignition switch of the vehicle being received from an MCU.

A steering wheel locking control method comprising:
- receiving power from a battery through a power supply switch which is turned on when an ignition switch of a vehicle is turned off;
- locking a steering wheel through a closed circuit formed by shorting phases of a motor, as one or more switches of a switch unit connected to the motor are turned on when power is received through the power supply switch;
- and
- controlling, by a protection circuit, the one or more switches of the switch unit not to operate, regardless of the operation of the power supply switch, when a control signal according to turn-on of the ignition switch of the vehicle is received from an MCU.

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.
