1. A parking system, comprising:
a torque-generating motor;
a final drive including side gears so coupled with the motor as to output torque from the motor to respective driving wheels of a vehicle, and including a differential gear with a lock to prevent a differential motion between the side gears, and an actuator for releasing the lock;
an ignition key having an ON position and an OFF position; a differential-lock switch having an open position and a closed position; a switching unit for selecting whether the actuator is turned on or off;
a controller electrically connected to the ignition key, the differential-lock switch, and the switching unit to control the actuator, the controller configured to, when the ignition key is detected to be in the OFF position, turn off the actuator if the differential-lock switch is in the open position, and execute no operation about the actuator if the differential-lock switch is in the closed position, whereby the differential motion of the differential gear is locked in either case to park the vehicle;
a shifter at least having a drive position and a neutral position; and
a brake for braking the motor, wherein the controller is electrically connected to the shifter and the brake and configured to
put the brake into operation if the ignition key is in the ON position and the shifter is in the neutral position.
