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.

An electric generation control system for use on a hybrid vehicle having a vehicle propelling apparatus including a battery and a propulsive electric motor energizable by the battery, and an electric energy generating apparatus including an engine and a generator actuatable by the engine, the generator being operable in a generator mode in which when the vehicle propelling apparatus is in operation, the generator is actuated by the engine to generate electric energy to be supplied to the battery and/or the propulsive electric motor, and when the hybrid vehicle is decelerated, the propulsive electric motor is subjected to regenerative braking and regenerated electric energy produced thereby is supplied to the battery, said electric generation control system comprising: target generated output setting means for determining a target generated output for the generator based on an operating condition of the hybrid vehicle; intake air control valve control means for controlling the opening of an intake air control valve of the engine to enable the engine to produce a power output corresponding to said target generated output; regenerative braking detecting means for detecting regenerative braking of the propulsive electric motor; and correcting means for correcting the opening of the intake air control valve of the engine depending on the target generated output in a direction to decrease when regenerative braking of the propulsive electric motor is detected by said regenerative braking detecting means.
