Method of Transmitting the Power of a Hybrid Vehicle Between a Heat Engine Shaft and a Wheel Axle Shaft of the Vehicle

摘要

The invention relates to a method of transmitting power between a shaft ( 10 ) of a heat engine ( 2 ) and a wheel ( 6 ) axle shaft ( 12 ) of a hybrid vehicle. The inventive method involves the use of: a power transmission device ( 1 ) comprising an electric machine ( 4 ) which is connected to (i) the heat engine by means of a clutch ( 3 ) and (ii) a wheel ( 6 ) axle shaft ( 12 ); and a starting system ( 31 ) which is mechanically independent of the electric machine ( 4 ) and which is connected to the heat engine ( 2 ). According to the invention, the heat engine ( 2 ) is started by applying a torque to the shaft ( 10 ) simultaneously using the starting system ( 31 ) and the clutch ( 3 ).
