ABSTRACT:
A motor needs to provide a first torque at the time of releasing a shift range from a parking range and needs to provide a second torque smaller than the first torque at the time of placing the shift range into the parking range. Also, the motor needs to provide a third torque smaller than the second torque at the time of changing the shift range from one non-parking range to another non-parking range and needs to provide a fourth torque smaller than the third torque at the time of executing the parking range wall abutment learning. When the parking range wall abutment learning is executed from the parking range, a motor control apparatus controls the torque to the third or fourth torque. When the parking range wall abutment learning is executed from any non-parking range, the motor control apparatus controls the torque to the first or second torque.
