Abstract:
A control system for controlling a hybrid vehicle having an engine for rotating a drive axle, an electric motor for assisting the engine in rotating the drive axle with electric energy and converting kinetic energy of the drive axle into electric energy, and electric energy storage means for supplying electric energy to the electric motor and storing electric energy outputted by the electric motor, comprising:remaining capacity detecting means for detecting a remaining capacity of the electric energy storage means; anddecelerating regenerative control means for establishing an amount of electric energy to be regenerated by said electric motor when the hybrid vehicle decelerates depending on at least a vehicle speed of the hybrid vehicle, and causing said electric motor to regenerate the established amount of electric energy;said decelerating regenerative control means comprises means for correcting said amount of electric energy to be regenerated by said electric motor depending on the remaining capacity of the electric energy storage means as detected by said remaining capacity detecting means and means for establishing said amount of electric energy to be regenerated by said electric motor such that said amount of electric energy to be regenerated by said electric motor, prior to being corrected depending on the remaining capacity of the electric energy storage means as detected by said remaining capacity detecting means, increases as said vehicle speed is higher.
