    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.

    摘要： A method of controlling electric motor torque in an electric vehicle for improved vehicle performance and energy conservation includes receiving a throttle torque request and a brake torque request, and sensing the speed of the vehicle. The brake torque request is split into a creep cancellation component and a brake regenerative component. The throttle torque request is adjusted based upon the creep cancellation component and the brake regenerative component to produce a torque sum. The electric motor torque is then controlled based upon the torque sum.
