Abstract
A hybrid vehicle is provided that can be made to travel by means of motor generators (MG, MG) while an engine (E) is stopped, the engine (E), which can reduce pumping loss by running with a cylinder in a cut-off state, being connected to a front wheel (Wf) via the first motor/generator (MG), an oil pump (), a first clutch (), a belt type continuously variable transmission (M), and a second clutch (), and the second motor/generator (MG) being connected to a rear wheel (Wr). When the vehicle is made to travel by driving or braking the rear wheel (Wr) with the second motor/generator (MG), by driving the oil pump () with the first motor/generator (MG) in a state in which the engine (E), which has stopped running, is put into a cylinder cut-off state and the second clutch () is disengaged, a hydraulic pressure for shifting the belt type continuously variable transmission (M) is generated. It is thereby possible to generate a hydraulic pressure for shifting the belt type continuously variable transmission (M) while the engine (E) is stopped, without requiring a special electric oil pump.
