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).
