Patent ID: 7490685

Claim:
A hybrid vehicle in which an engine (E) equipped with pumping loss reduction means is connected to a first driven wheel via a first motor/generator (MG 1 ), an oil pump ( 13 ), a first clutch ( 14 ), a hydraulic automatic transmission (M), and a second clutch ( 20 ), and a second motor/generator (MG 2 ) is connected to a second driven wheel (Wr), the second driven wheel (Wr) being different from the first driven wheel (Wf), characterized in that when the vehicle is made to travel by driving or braking the second driven wheel (Wr) with the second motor/generator (MG 2 ), in order to shift the automatic transmission (M) a hydraulic pressure is generated by driving the oil pump ( 13 ) with the first motor/generator (MG 1 ) in a state in which the pumping loss of the engine (E), which has stopped running, is reduced by the pumping loss reduction means and the second clutch ( 20 ) is disengaged.
