Abstract
A control system for a hybrid vehicle, which enables the hybrid vehicle to optimally selectively use driven modes to attain excellent fuel economy and thereby make it possible to improve fuel economy. The hybrid vehicle is operated in an engine-driven mode or a motor-driven mode, and recovers electric energy for driving an electric motor, using the output from the engine. The control system calculates a driving fuel consumption amount of the engine required for driving the hybrid vehicle in the engine-driven mode and a recovering fuel consumption amount of the engine required for recovering electric energy to be consumed when the hybrid vehicle is driven in the motor-driven mode, and sets the driven mode to the motor-driven mode when the recovering fuel consumption amount is smaller than the driving fuel consumption amount, and to the engine-driven mode when the former is larger than the latter.
