  • Electric power generation control device for motor vehicle
    Patent number: 8143741
    Abstract: An electric power generation control device for a motor vehicle is provided which ensures a satisfactory regenerative effect without entailing flickering of or reduction in life of headlights even if the headlights are turned on at all times. The electric power generation control device lowers the power generation voltage of an alternator when the electricity storage amount of a battery is at or above a predetermined level. While lighting of a headlight bulb is detected, lowering of the power generation voltage is restrained if the state of sunlight is equivalent to nighttime, and the power generation voltage is allowed to be lowered if the sunlight state is equivalent to daytime.
    Type: Grant
