Method and device for damping control of oscillating modes of a continuously variable transmission provided with an electric variator& x9;

摘要

The process involves calculating a control torque of electric machines which is the sum of a main control signal (Uo1) permitting to attain wheel torque threshold signal (RTo), and a heat engine torque signal (RWice). An additional control signal (Um) is obtained which depends on the signals (RTo, RWice) and physical amplitude estimations. The signal (Um) is made of a threshold component and a vector component. An independent claim is also included for a drive train controlling device.
