Apparatus for controlling generator for vehicle
This patent describes a control apparatus for a vehicle generator having an output voltage connected to a battery, the apparatus controlling the output voltage of the generator by controlling the field winding current of the generator comprising: an operating state detector for detecting an operating state of the vehicle and for generating an output signal representative; a reference clock generator for producing reference clock pulses; regulator means connected to the field winding for varying the field current and controlling the output voltage of the vehicle generator to a predetermined regulated value in accordance with modulated reference clock pulses; and a modulator means operated responsive to an output signal from the operating state detector for gradually changing the width of the reference clock pulses upon the occurrence of the operating state for gradually varying the field current to gradually reduce the output voltage of the generator connected to the battery over a predetermined period after the occurrence of the operating state of the vehicle.
