Abstract: A shift-by-wire system configured to switch shift positions includes a detent plate, a detent spring, a rotating electrical machine, a gear device, and an electronic control unit. The electronic control unit provided in the shift-by-wire system is configured to control a rotating electrical machine torque. The electronic control unit is configured to reverse the rotating electrical machine torque after the electronic control unit makes the rotating electrical machine output the rotating electrical machine torque for turning the detent plate in a turning direction to switch the shift position, then the detent torque generated in the detent plate by a push of the engagement portion is reversed in the turning direction from a counter-turning direction opposite to the turning direction, and before backlash elimination in a backlash portion of the gear device by the reversed detent torque is finished.

Abstract: A vehicle drive-force transmitting apparatus including: a casing; a drive-force transmitting mechanism disposed in the casing; and first and second oil pumps configured to suck, through respective inlet ports thereof, oil stored in a bottom portion of a casing, such that the drive-force transmitting mechanism is lubricated by the oil pumped up by the first and second oil pumps. The casing is provided with a drain hole through which the oil stored in the bottom portion of the casing is to be discharged to an exterior of the casing. A position of opening of the inlet port of the first oil pump is lower than a position of a lower end of the drain hole, and a position of opening of the inlet port of the second oil pump is higher than the position of the lower end of the drain hole.

Abstract: A rotation speed of an electric oil pump in the case where an accelerator operation amount falls within a predetermined range is controlled to a rotation speed lower than the rotation speed of the electric oil pump in the case where the accelerator operation amount falls outside the predetermined range. When the range outside the predetermined range of the accelerator operation amount is set to a range in which noise that occurs from a source other than the electric oil pump is large, noise that occurs from the electric oil pump is masked by the noise that occurs from a source other than the electric oil pump and becomes inconspicuous in this range even when the rotation speed of the electric oil pump increases.
