摘要:
The present invention provides a method for reducing torsional vibration in a vehicle drivetrain. The method comprises detecting a rotational speed of the drivetrain to generate a rotational speed signal. The method also includes generating a vibration compensating torque command which is a function of a frequency content of the rotational speed signal. The present invention further provides a system for reducing torsional vibration in a vehicle drivetrain. The system includes a source of torque, a drivetrain coupled to receive torque from the source of torque and a speed detector adapted to detect a rotational speed of the drivetrain and generate a rotational speed signal. The system additionally includes an electronic controller coupled to the source of torque and programmed to provide operational command signals to the source of torque. The system further comprises a frequency detector having an input and an output, the input coupled in electrical communication with the speed detector to receive the rotational speed signal and the output coupled in electrical communication with the electronic controller.
