Abstract:
A P-range side delimiting position of a movable range of a range change mechanism is learned by rotating a motor to a corresponding rotational position, which corresponds to the P-range side delimiting position. A climb correction amount is set for a learning value of the P-range side delimiting position to correct the learning value of the P-range side delimiting position in view of presence of a relatively small angle of rotation of the motor beyond the corresponding rotational position, which corresponds to the P-range side delimiting position. The climb correction amount is set according to motor temperature information, which is one of a temperature of the motor and a temperature that relates to the temperature of the motor.
