Abstract
A vehicle generator controller for regulating the output voltage from a generator which charges a battery mounted on a vehicle comprises battery voltage detection means for detecting the drop of a battery voltage, a switching element for controlling the field current of the generator, gradual increase control means for gradually increasing the current generated by the generator by gradually increasing the switching element by intermittently operating the switching element when the battery voltage drops and gradual increase prohibition means for canceling the gradual increase control at the beginning of the drop of the battery voltage and gradually increases the field current after the conducting ratio of the switching element is set to 100%. With this arrangement, the vehicle generator controller suppresses a torque shock caused in response to the turn-on of an electric load as well as sufficiently suppresses the drop of a battery voltage.
