METHOD FOR CONTROLLING A CONTINUOUSLY VARIABLE COEFFICIENT TRANSMISSION DEVICE IN A HYBRID TRACTION CHAIN OF A MOTOR VEHICLE

摘要

The method relates to controlling a continuously variable coefficient transmission device (3) in a hybrid traction system of a motor vehicle comprising an energy storage device (2) connected at the input of the coefficient transmission device. continuously variable, and wheels (6) connected at the output of the continuously variable transmission device via a bridge (5), the control being performed by comparing a torque setpoint to the wheel with a current value of torque to the wheel, which is calculated using a time derivative of a ratio between an input value and an output value of a variable data of the continuously variable coefficient transmission device.
