ABSTRACT:
Before an amount of play in a rotation transmitting system is learned, for selecting a gear range, an overshooting control process is performed to cause the angular displacement of a motor to overshoot a target gear range position and then reverse the electric motor. The angular displacement of the motor overshoots the target get gear range position by an overshooting amount that is identical to am amount by which the electric motor is reversed. The overshooting amount is set to a maximum value of a designed amount of play in the rotation transmitting system After the amount of play is learned, for selecting a gear range, a target count is established in view of the learned amount of play and the direction in which the motor rotates, and the motor is stopped at a position where an encoder pulse count coincides with the target count without performing the overshooting control process.
