    • 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.
    • 电动机需要在从停车范围中释放换档范围时提供第一扭矩,并且需要在将换档范围放置在停车范围时提供小于第一扭矩的第二扭矩。 此外,电动机需要在将变速范围从一个非停车范围改变到另一个非停车范围时提供小于第二转矩的第三转矩,并且需要提供比此时的第三转矩小的第四转矩 执行停车场墙基台学习。 当从停车范围执行停车场壁基台学习时,马达控制装置将扭矩控制到第三或第四扭矩。 当从任何非停车范围执行停车范围壁基台学习时,马达控制装置将扭矩控制为第一或第二扭矩。

    • A shift range switching device is provided to a shift-by-wire system for an automatic transmission device. The shift range switching device includes a range switching unit for switching a shift range of the automatic transmission device between a P range and the other range. The shift range switching device further includes an actuator including an electric motor and a reduction device. The reduction device transmits driving force of the electric motor to the range switching unit for actuating the range switching unit as instructed. The reduction device has a variable reduction ratio. The reduction device transmits the driving force in switching of the shift range from the P range to the other range at a reduction ratio, which is greater than a reduction ratio in switching of the shift range from the other range to the P range.
