A first retaining ring is disposed between a first outer circumferential groove provided in an outer circumferential surface of a radial bearing, and an inner circumferential groove of a cylindrical portion of a transmission case. A ring piece is provided with an outer ring of the radial bearing. The ring piece protrudes outward in a radial direction and is in contact with an output gear side end surface of the cylindrical portion in the axial direction. A return spring urges the piston in a direction opposite to a direction in which the pressure is applied by the piston. The return spring is retained in the axial direction by a second retaining ring. The second retaining ring is locked in a second outer circumferential groove of the ring piece.

Automatic transmission

To provide a parking support device for easily and quickly moving or rotating a target parking frame to an appropriate position. The parking support device includes a target parking position setting unit configured to set a target parking position at which a vehicle is to be parked with a target parking frame superimposed on an actual image displaying an area surrounding the vehicle. The parking support device guides the vehicle to the target parking position set by the target parking position setting unit. The target parking position setting unit moves the target parking frame initially displayed on a touch display to a position indicated by a coordinate point determined by a touch operation.

Parking support device

A parking assist apparatus for guiding a vehicle to a target parking position includes an initial position guiding unit configured to generate an initial position guiding path at a predetermined timing, the initial position guiding path leading from a current position of the vehicle to an initial position where vehicle guidance to the target parking position is started. The initial position guiding unit is also configured to guide the vehicle along the initial position guiding path to the initial position. The apparatus also includes an obstacle detecting unit configured to detect an obstacle around the vehicle. When the obstacle detected by the obstacle detecting unit is located along the initial position guiding path, the initial position guiding unit generates the initial position guiding path such that the obstacle detected by the obstacle detecting unit can be avoided.

Parking assist apparatus

A parking assisting device includes an ambient area detecting unit that detects an obstacle or a parking frame in an ambient area surrounding a vehicle, and a guiding unit guides the vehicle to a parking initial position from which parking of the vehicle to a parking space, adjacent to the detected obstacle, or the detected parking frame is permissible. In the parking assisting device, a guidance mode in which the guiding unit guides the vehicle to the parking initial position is set up based on a distance between the vehicle and the detected obstacle or the detected parking frame in a vehicle width direction of the vehicle.

Parking assistance device and parking assistance method

A parking assistance device includes a guiding unit to perform guidance of a vehicle to a parking initial position from which the vehicle can be parked into a parking space located adjacent to and on a far side of an object existing around the vehicle with respect to a running direction of the vehicle; an obstacle detecting unit to detect an obstacle around the vehicle in response to a reflected wave of a wave emitted from the vehicle in a predetermined direction; and a timing setting unit configured to set a timing to start the guidance in response to a detection result of the obstacle detecting unit, which is related to an obstacle existing in a predetermined distance from the object in the parking space.

Parking assistance device

An embodiment of a differential device of the present invention comprises a pair of side gears and a pair of pinion gears housed inside a differential case, with the pinion gears supported by a pinion shaft fixed to the differential case at axial end sections thereof so as to be capable of sliding freely thereabout. Lubricating oil channels are provided that pass through each of the end sections of the pinion shaft in the axial direction thereof. One end of each lubricating oil channel opens to the exterior of the differential case at a shaft-end corner section of the pinion shaft corresponding to an upstream side thereof in a direction of rotation of the differential case, and another end opens to a sliding surface of the pinion shaft with respect to one of the pinion gears. The differential device also comprises a mechanism for providing lubricating oil to the lubricating oil channels upon rotation of the differential case.

Differential device

When a deceleration slip executing minimum gear stage is not established in a state of continuously executing a deceleration slip control at a target slip amount, it is judged whether or not an input shaft rotational speed of a transmission becomes a down shift judging rotational speed. When it becomes equal to or less than a predetermined down shift judging rotational speed, a down shift is executed, and a clutch pressure is controlled such that an engine rotational speed becomes a target engine rotational speed.
