Abstract:
A motor-generator system comprising an internal combustion engine, a motor-generator in driven engagement with the internal combustion engine by an endless belt, the motor-generator, a controller detecting a speed signal of the internal combustion engine, a driver input signal, a battery state signal and a motor-generator signal, the motor-generator operable to provide a motoring torque or a load torque to the internal combustion engine at a predetermined frequency according to a controller command, and the controller controlling the motor-generator torque at a frequency greater than 1 Hz such that when the internal combustion engine accelerates the motoring torque is applied to speed the motor-generator rotation and when the internal combustion engine decelerates the load torque is applied to slow motor-generator rotation such that motor-generator rotation is controlled to attenuate a system vibration.

Claim (Index 1):
A method of controlling a motor-generator torque comprising:\n measuring an engine speed; detecting a motor-generator acceleration or deceleration; calculating a motor-generator inertia torque using the acceleration or deceleration; determining a threshold torque; determining if the motor-generator inertia torque is greater than or less than the threshold torque; applying a driving torque to the motor-generator to damp a system vibration if the motor-generator inertia torque is greater than the threshold torque; applying a load torque to the motor-generator to damp a system vibration if the motor-generator inertia torque is less than the threshold torque; and applying the driving torque and load torque at a frequency in the range of approximately 1 Hz to approximately 50 Hz.
