Apparatus for controlling generation of power in vehicles

摘要

The present invention provides, as one aspect, an apparatus (2) for controlling generation of power in vehicles which include a generator (1) having a field winding (102) and a battery (3). The apparatus comprises a voltage comparing section (207, 208, 204, 206) that compares either output voltage of the generator (1) or terminal voltage of the battery (3) with a predetermined regulation voltage, a field current controlling section (202) that controls field current passing through the field winding (102) of the generator (1), a field current suppressing section (203, 205, 213) that drives the field current controlling section (202) based on a comparison result of the voltage comparing section (207, 208, 204, 206) to suppress the field current, and an external output terminal (C) that transmits either a first signal outputted from the voltage comparing section (207, 208, 204, 206) and inputted into the field current suppressing section (203, 205, 213) or a second signal corresponding to the first signal.
