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 electric 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.
