Abstract
A system for selectively consuming and storing electrical energy in a hybrid vehicle. The system includes an electric motor/generator unit having a rotary shaft and an internal combustion engine having a main shaft. A continuously variable transmission mechanically couples the electric motor/generator rotary shaft to the engine main shaft. A control circuit varies the amount of torque of the electric motor/generator unit rotary shaft between a negative and a positive value as a function of the operating condition of the vehicle. The control circuit also controls the transmission to vary the transmission ratio as a function of the engine operating conditions.
