A hybrid vehicle with control of the amount of discharge from an oil pump in accordance with the amount needed. The hybrid vehicle includes an oil pump (55) driven by a rotation from a secondary side (a carrier CR) of a one-way clutch (F1), an engine (11), a generator (16), and an output shaft (14)

A hybrid vehicle with control of the amount of discharge from an oil pump in accordance with the amount needed. The hybrid vehicle includes an oil pump (55) driven by a rotation from a secondary side (a carrier CR) of a one-way clutch (F1), an engine (11), a generator (16), and an output shaft (14) connected by a planetary gear unit (13). The one-way clutch (F1) is provided between the carrier (CR) of the planetary gear unit (13) and the engine (11). The rotation of the carrier (CR) via the planetary gear unit (13) is adjusted by controlling the generator (16) under command of a vehicle control unit (41), to appropriately adjust the amount of discharge from the oil pump (55) based on a detected running load.
