1. A charge control microcomputer device for a vehicle, comprising:

  • an AC generator driven by an engine for generating an output current, said generator having armature coils and a field coil;

    a battery charged by a rectified output of said generator and generating a terminal voltage;

    a voltage regulator for controlling a current flowing in said field coil, to control an output voltage of said generator to a predetermined value;

    an engine controlling microcomputer for receiving engine parameter data from said engine, to control the operation of said engine;

    a charge control microcomputer for processing input data including data on at least one engine parameter output from said engine controlling microcomputer, and charge system data including at least one of battery terminal voltage data, generator voltage data and generator output current data, to provide a reference voltage for said voltage regulator.
