Abstract: A transmission unit is able to switch between a non-neutral state where power of an engine is transmitted via a path K1 and a neutral state where power of the engine is not transmitted via the path K1. A clutch is able to switch between an engaged state where power is transmitted from the engine to a first MG and a released state where transmission of power from the engine to the first MG is interrupted. When the transmission unit is controlled to the non-neutral state and, at the same time, the clutch is set to the released state, a vehicle is operable in series-parallel mode. When power is transmitted via the path K2 by directly coupling the engine to the first MG by the clutch and the path K1 is interrupted by controlling the transmission unit to the neutral state, the vehicle is operable in series mode.

Abstract: A hybrid vehicle includes an engine (10), a first motor generator (MG1), a second motor generator (MG2), a transmission unit (power transmission unit) (40), a differential unit (50), a clutch (CS) and a mechanical oil pump (501). The hybrid vehicle is able to switch between series-parallel mode in which power of the engine is transmitted via the transmission unit and the differential unit and series mode in which power of the engine is transmitted via the clutch. The differential unit (50) is a planetary gear mechanism including a sun gear (S2) connected to the first motor generator (MG1), a ring gear (R2) connected to the second motor generator (MG2), and a carrier (CA2) connected to a ring gear (R1) that is an output element of the transmission unit (40). The mechanical oil pump (501) is driven by power that is transmitted from the carrier (CA2) of the differential unit.

Abstract: A manual release device for a parking lock mechanism includes an operating lever, a cable and an idle motion mechanism. The idle motion mechanism includes a body portion, a lever provided on the body portion, a helical compression spring, and a contact portion provided on the shaft. The cable is coupled to the lever. A distal end of the lever is arranged below a turning center of the lever. The parking lock mechanism is configured, when the parking lock mechanism is in a locked state, to be switched into an unlocked state as the body portion contacts the contact portion to cause the shaft to turn when the lever is turned against an urging force of the urging member as a result of operation of the operating lever to cause the body portion to turn from the normal position to the actuated position.

Abstract: A manual unlocking device for a parking lock mechanism includes an operation lever that rotates when the parking lock mechanism is switched from a locked state to an unlocked state. The operation lever is arranged outside an occupant space of a vehicle cabin and is configured that a tool can be coupled to a rotation center thereof from the occupant space. The manual unlocking device for the parking lock mechanism is configured to switch the parking lock mechanism from the locked state to the unlocked state by integral rotation of the operation lever with the tool when the tool, which is coupled to the operation lever, rotates in a state where the tool is arranged on the rotation center of the operation lever.
