ABSTRACT:
A vehicle generator control device comprises a detector adapted to detect whether or not a lamp load has been applied; and a control circuit. When an electric load is applied (i.e., when the terminal voltage of a battery is lowered) under the condition that the application of the lamp load has been detected, the control circuit suspends a load response control operation (increasing the field current of the generator by turning the field current switch on and off), and instead increases the field current abruptly by maintaining the field current switch conductive, thereby to increase the terminal voltage of the battery immediately. Thereby, a vehicle generator control device is provided which is free from a difficulty that, when a load response control operation is carried out with lamps with head turned on, the output light of these lamps are decreased or the lamps flicker.
