Vehicle generator controller
First Claim
1. A vehicle generator controller for regulating a voltage output by a generator for charging a battery mounted on a vehicle, comprising:
- battery voltage detection means for detecting the drop of the voltage of the battery;
a switching element for controlling the field current of the generator;
gradual increase control means for gradually increasing the field current by intermittently operating said switching element when the battery voltage is lowered to thereby gradually increasing the current generated by the generator; and
gradual increase prohibition means for outputting a conducing signal for canceling the gradual increase control at the beginning of the drop of the battery voltage, wherein when the battery voltage drops, the conducting ratio of said switching element is set to 100% and thereafter the field current is gradually increased.

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.
