Abstract:
A control system is disclosed for minimizing the driveline vibrations in a hybrid electric vehicle during engine engagement. The control system involves determining the speed of the electric motor and taking the derivative of the speed to determine the acceleration. A signal representing the acceleration is created. The acceleration signal is filtered. The filtered acceleration signal is used to calculate a feedback control term through a controller. The controller can be either a PD controller or a PID controller with a low integral gain. The feedback control term is used to adjust the output torque of the electric motor to suppress the vibrations caused by engine engagement.
