Abstract

A vehicle having an electric generator control apparatus is provided for gradually reducing an engine load imposed due to electricity generation while a throttle valve is in the process of becoming fully open, thereby increasing a vehicle acceleration capability. The electric generator control apparatus is incorporated in a vehicle which has an ACG starter motor for generating electric power from power of an engine and supplying the generated electric power to a battery and other electric loads. When an engine throttle opening exceeds a preset value, the electric generator control apparatus continuously gradually reduces the amount of electric power generated by the ACG starter motor depending on the throttle opening in a fully opening direction which exceeds the preset value. The load imposed on the engine by electricity generation is gradually reduced, resulting in a corresponding increase in the acceleration capability of the vehicle.

Description

technical field [0001] The invention relates to a control device of a generator for generating electricity by using engine power and a vehicle equipped with the device. Background technique [0002] Vehicles such as two-wheeled vehicles are equipped with generators that generate electricity using engine power. A generator is used to supply electrical loads such as batteries or lighting, and usually generates electricity as the engine rotates. However, power generation by the generator consumes the power of the engine, so when the generated electric power is large, driving of the vehicle by the engine is limited accordingly. Specifically, for example, when accelerating with a fully open throttle, if the generated power of the generator is set to be large, the increase in engine output and the peak value of the output are suppressed accordingly. Furthermore, the influence on the engine output due to the increase in generated electric power is particularly noticeable in a veh...
