Active motor damping control of a hybrid electric vehicle powertrain
Abstract:
A hybrid electric vehicle includes an engine and an electric motor both configured to generate a vehicle powertrain torque and a controller programmed to control the powertrain torque for a limited duration in anticipation of a powertrain torque variation scenario using a damping function, wherein the damping function adjusts the vehicle powertrain torque based on a difference between a measured motor speed and a desired motor speed using the electric motor to counteract a powertrain speed oscillation.
