DAMPING OF POWER TRAIN OSCILLATIONS

摘要

A method for damping of a power train oscillation in a vehicle provided with a prime mover which delivers a torque related to a torque request M from a vehicle system and rotates at a speed ω. A cyclic variation S in the rotation speed ω of said prime mover is determined. The torque request M is then given an oscillation-damping characteristic by use of the cyclic variation S, making it possible for the power train oscillation to be effectively damped out.
