Abstract
A control system controls 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 an electric energy storage unit for supplying electric energy to the electric motor and storing electric energy outputted by the electric motor. The control system has a deceleration demand sensor for detecting a deceleration demand for the hybrid vehicle, a braking sensor for detecting whether the hybrid vehicle is braked or not, and a decelerating regenerative control unit for causing the electric motor to regenerate electric energy when the deceleration demand sensor detects the deceleration demand. The decelerating regenerative control unit increases an amount of electric energy regenerated by the electric motor, by a greater quantity when the hybrid vehicle is braked as detected by the braking sensor than when the hybrid vehicle is not braked as detected by the braking sensor, while the deceleration demand sensor is detecting the deceleration demand.
