CONTROL METHOD FOR A TRANSMISSION DEVICE BETWEEN A HEAT ENGINE SHAFT AND AN AXLE SHAFT OF A VEHICLE

摘要

The invention essentially relates to a method of controlling a device (1) for the transmission of power between a shaft (2) of a heat engine (3) and an axle shaft (4). The inventive method involves the use of two electrical machines (6, 7), namely a first machine having a rotation speed WA and a torque CA and a second machine having a rotation speed WB and a torque CB. A coupling device (11) comprises an electric controller (27) which produces set point signals RefCA and RefCB for controlling the inverters (12, 13). According to the invention, in order to produce set point signals RefCA and RefCB, an electric reference signal RefELEC corresponding to CA*WA+CB*WB and a mechanical reference signal RefMECA corresponding to CA*WB-CB*W A are applied at the inputs of the control device.
