Abstract
The opening of the intake air control valve of an engine which actuates a generator on a hybrid vehicle is basically controlled by an intake air control valve control assembly to cause the engine to produce a power output corresponding to a target generated output which is determined by a target generated output setting assembly based on an operating condition of the hybrid vehicle. When regenerative braking of a propulsive electric motor is detected by a regenerative braking detector, the opening of the intake air control valve is corrected in a direction to decrease. Even when the load on the engine drops sharply or is greatly reduced by regenerative braking of the propulsive electric motor, the engine is prevented from racing, and from discharging unwanted exhaust emissions and also from suffering undue vibrations.
