Abstract: A parking lock mechanism comprises: a parking gear disposed on a power transmission member mechanically coupled to a drive wheel; and a parking pawl provided with a lock claw configured to mesh with the parking gear and switching between a lock state in which the lock claw is meshed with the parking gear and an unlock state in which meshing between the lock claw and the parking gear is released. In the mechanism, the lock claw includes a first end surface and a second end surface opposite to each other in a face width direction, the lock claw includes a tooth tip surface provided with a retreated portion at a corner on the second end surface side, and a position of a center of gravity of the parking pawl is on the second end surface side relative to a center plane in the face width direction of the lock claw.

Abstract: A vehicle control apparatus configured to selectively establish one of a first drive state in which a vehicle drive force is generated primarily by a second motor/generator operated with an electric energy supplied from an electric-energy storage device while an engine is placed in a rest state, and a second drive state in which a first motor/generator is operated with a drive force of the engine, to generate an electric energy and in which the vehicle drive force is generated primarily by the second motor/generator operated with at least the electric energy generated by the first motor/generator. The vehicle control apparatus is further configured such that the vehicle drive force generated in the second drive state at a given value of an accelerator pedal operation amount θacc is larger than that generated in the first drive state.

Abstract: A parking device includes a parking gear, a parking pawl, and a torsion spring. The parking gear is directly coupled to an axle. The parking pawl is pivotably supported by a fulcrum pin and provided with a claw configured to be able to mesh with a tooth space of the parking gear. The torsion spring is fitted on the fulcrum pin, with a first end of the torsion spring mounted on the parking pawl and a second end of the torsion spring mounted on a holding member that holds the fulcrum pin.
