Patent ID: 7329966

Claim:
A vehicle-mounted electrical generator control system for controlling an electrical generator that is driven by a vehicle engine, said electrical generator producing a generated current for supplying respective load currents to a plurality of electrical loads and a charging current of a battery of said vehicle, said system including: voltage regulator means for controlling said electrical generator to produce a regulated output voltage, and generator control means for deriving a currently obtained value of said generated current and for calculating a target value of said generated current and for sending target command information indicative of said target value to said voltage regulator means, said target value being determined based upon factors including a condition of said storage battery and a utilization status of said electrical load(s); wherein said generator control means comprises: load disconnection timing detection means for detecting a disconnection time point, at which a specific one of said plurality of electrical loads is to be disconnected from said electrical generator while continuing to supply said respective load currents to remaining ones of said plurality of electrical loads and continuing to supply said charging current, with said disconnection time point being detected at a pre-disconnection time point prior to said load disconnection time point, based on condition information relating to said specific electrical load, generated output calculation means for calculating, as a specific load current value, a value of current that is being supplied to said specific one of said plurality of electrical loads, based on a value of electrical power that is being consumed by said specific one of said plurality of electrical loads prior to said disconnection, and generated output control command means responsive to information from said load disconnection timing detection means and said generated output calculation means for transmitting to said voltage regulator means, prior to said disconnection time point, target command information specifying a value of said generated output current that is decreased from said currently obtained value thereof by an amount equal to said specific load current value.
