International ClassB60K 041/02Foreign Application Priority Data1998-03-20 JPAbstractA hybrid vehicle propulsion system comprises an electric motor as a first propulsion source, an engine as a second propulsion source and a continuously variable transmission for receiving an input rotation from at least one of the motor and engine and for delivering a driving torque to a drive axle of the vehicle. A controller controls a transmission ratio of the transmission so that the transmission ratio in a motor drive mode is higher than the transmission ratio in an engine drive mode. | |
