Abstract:
A control system for controlling a hybrid vehicle having an engine as a vehicle propulsion source, an electric energy storage device for storing electric energy, and a generator/motor for selectively operating as an electric motor for generating an assistive output to assist in an output of the engine from the electric energy stored in the electric energy storage device and as an electric generator for generating electric energy to be stored in the electric energy storage device, said control system comprising:generator/motor control means for controlling operation of said generator/motor to maintain a current passing through said electric energy storage device at a level equal to or smaller than a predetermined limiting value established depending on the amount of electric energy stored in said electric energy storage device, when said generator/motor operates as the electric motor, and to maintain a current passing through said electric energy storage device at another level equal to or smaller than another predetermined limiting value established depending on the amount of electric energy stored in said electric energy storage device when generator/motor operates as the electric generator.
