Motor-generator system
First Claim
1. 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 comprising;
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 of rotary vibration 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.
