ABSTRACT:
A hybrid vehicle has an engine as a propulsive power unit for the hybrid vehicle, an electric energy storage device for storing electric energy, and a generator motor operable alternatively as an electric motor for generating an assistive output power to be added to an output power generated by the engine, from the electric energy stored by the electric energy storage device, and as an electric generator for regenerating electric energy to be charged into the electric energy storage device. A control system regards an integrated charged quantity which represents an integrated value of electric energy quantity charged from the generator motor into the electric energy storage device when the generator motor operates as the electric generator, as an allowable discharged quantity of the electric energy storage device when the generator motor operates as the electric motor, and limits an integrated discharged quantity which represents an integrated value of electric energy quantity discharged from the electric energy storage device when the generator motor operates as the electric motor, within the allowable discharged quantity. The control system also corrects the allowable discharged quantity depending on the electric energy quantity stored by the electric energy storage device when the generator motor starts operating as the electric motor.
