摘要： A power transmission unit in which an oil pump is arranged without extending a shaft length. In the power transmission unit, an input shaft, a first rotary machine, a differential mechanism, and an output shaft are arranged coaxially. The power transmission unit comprise: a first clutch that engages a first movable member connected to an input element of the differential mechanism with a first engagement section formed on another rotary element; a second clutch that engages a second movable member connected to the output element of the differential mechanism with a second engagement section formed on another rotary element; a drive gear mounted on the input element; a driven gear meshed with the drive gear; and an oil pump connected to the driven gear.

摘要： A driving force control system for a hybrid vehicle for reducing a required time to launch the hybrid vehicle after selecting a reverse range while maintaining a driving force. The control system is configured to change an engine start threshold to restrict a startup of the engine upon satisfaction of a restricting condition, in which a low mode is established by a transmission mechanism, and a reverse drive range is selected.

摘要： A control apparatus for a hybrid vehicle drive system, which permits effective reduction of deterioration of the drivability of the hybrid vehicle. The control apparatus includes a drive mode switching portion 60 configured to switch the hybrid vehicle drive system from a hybrid drive mode to a first EV drive mode if an electric energy amount stored in a battery is smaller than a predetermined threshold value α or if a vehicle drive force required to be generated by the hybrid vehicle drive system is smaller than a predetermined threshold value β, and to a second EV drive mode if the electric energy amount stored in the battery is equal to or larger than the threshold value α and if the drive force required to drive the hybrid vehicle is equal to or larger than the threshold value β, when the drive mode switching portion has determined that the hybrid vehicle drive system should be switched from the hybrid drive mode to the first or second EV drive mode.
