Electricity-generation control system for vehicle

Abstract

If a decelerating-state detecting device detects a decelerating state of a vehicle, an electricity-generation control device allows a dynamo to generate electricity through a regulator, thereby recovering a kinetic energy of the vehicle, wastefully consumed by braking, as electric energy to charge a battery. At the same time, a braking-force control device controls the opening of a throttle valve through an actuator, thereby decreasing the braking force generated by a pumping load of an engine to prevent a variation in total braking force, so that a sense of incompatibility is prevented from being felt by a driver. Even if the opening of an exhaust valve of an exhaust brake device is controlled instead of controlling the opening of the throttle valve, a similar function and effect can be achieved. Thus, it is possible to avoid a variation in braking force during deceleration of the vehicle, while suppressing the consumption of an engine power output due to the driving of the dynamo to a minimum.
