초록 ▼

A method for controlling a vehicle generator, by obtaining a first correction volume of an opening of an ISC valve (ISCPI) based on a deviation of a rotation number of an internal combustion engine from a target rotation number, obtaining a driving volume of an excitation coil of a generator based on a deviation of a battery voltage from a target voltage, and obtaining a second correction volume of an opening of the ISC valve (EL) that takes account of an electrical load variation based on a driving volume of the excitation coil and a rotation number of the internal combustion engine, to obtain a driving volume of the ISC valve (ISCDTY) based on the first and second correction volumes of the opening of the ISC valve.

대표청구항 ▼

[ We claim:] [1.] A control system for a vehicle generator, comprising: an internal combustion engine mounted on a vehicle; an operating unit for controlling a driving of said internal combustion engine; driving status detecting means for detecting a driving status of said internal combustion engine by detecting at least a rotation number of said internal combustion engine, an opening of a throttle valve and a temperature of a cooling water; intake air quantity adjusting means for adjusting a quantity of an intake air during an idling; a generator driven by said internal combustion engine, for generating power; an excitation coil incorporated in said generator, for controlling a generation volume; means for driving said excitation coil; a battery to be charged by power generated by said generator; and means for detecting a voltage of said battery, wherein said operating unit includes:means for setting a driving volume of said intake air quantity adjusting means;means for calculating a target generation voltage according to a driving status of said internal combustion engine;means for calculating driving volume (ALTDTY, 224) of said excitation coil so that a voltage of said battery comes close to said target generation voltage by comparing said target generation voltage with said battery voltage; andmeans for correcting a driving volume of said intake air quantity adjusting means by a first correction volume (ISCPI, 209) based on a rotation number of said internal combustion engine and a second correction volume (EL, 210) based on a driving volume of said excitation coil and said detected driving status.
