摘要： A power transmission control device acquires rotation speed information of an idle gear corresponding to a target engagement member and rotation speed information of a sleeve corresponding to an engagement member, sets one rotation speed changeable by a power source as a synchronization side rotation speed, sets the other rotation speed as a target synchronization side rotation speed, allows a differential rotation between the synchronization side rotation speed and the target synchronization side rotation speed to match a predetermined differential rotation by changing the synchronization side rotation speed using the power source after a power transmission releasing state is selected due to a gear changing request, performs an engagement operation, inverts a sign of the predetermined differential rotation, and switches to the power transmission state while allowing the differential rotation to match the predetermined differential rotation of which the sign is inverted.

摘要： A vehicle electric motor including: a tubular-shaped stator core constituted by laminated steel sheets; a casing including an outer circumferential wall and a bottom wall, and storing therein an axial end portion of the stator core; a casing cover including an outer circumferential wall and a bottom wall, and storing therein another axial end portion of the stator core, and a rotor disposed inside the stator core. The stator core includes fastened portions protruding radially outwardly from respective portions of an outer circumferential surface of the stator core which are circumferentially spaced apart from each other. The stator core is fastened at the fastened portions to the bottom wall of one of the casing and the casing cover. The other of the casing and the casing cover includes protrusion portions protruding from its inner wall surface toward the stator core so as to restrain inclination of the stator core.

摘要： A vehicle driving apparatus including: a fluid pump; a rotary member; a bearing supporting the rotary member; a pump cover covering the fluid pump; a relief valve; and a casing storing the fluid pump, the rotary member, the bearing, the pump cover and the relief valve. The casing includes a casing body and a casing cover. The casing cover defines a fluid passage that is in communication with an outlet port of the fluid pump, and includes cylindrical-shaped first and second boss portions. The first boss portion includes a supporting portion supporting the rotary member through the bearing which is fitted in a space radially inside the first boss portion. The second boss portion defines a valve room that is in communication with the fluid passage, with the relief valve being stored in the valve room.

摘要： To provide a technique for allowing a search for a route taking into account turnarounds in the entire way from a point of departure to a destination. A route search system includes a node obtaining part that obtains nodes present between a point of departure and a destination of a vehicle; a passage cost obtaining part that obtains a passage cost of a road section between the nodes and the passage costs of intersections represented by the nodes; and a route searching part that searches for a route with the smallest sum of the passage costs between the point of departure and the destination, and the route searching part sets the passage cost for a case of making a turnaround, for all of the intersections included in a candidate for a route from the point of departure to the destination, based on the road section traveled after the turnaround.
