Abstract
The present invention provides, as one aspect, an apparatus for controlling electric power generation for vehicles, which controls energization of an excitation winding of a generator driven by an internal-combustion engine controlled by a controller to control output voltage of the generator. The apparatus includes a restraining unit that restrains electric power generation of the generator in response to a given signal, and a releasing unit the releases the restraint by the restraining unit when generated voltage of the generator is equal to or less than a first predetermined value. The apparatus further includes a detecting unit that detects starting of the internal-combustion engine, a measuring unit that measures elapsed time from the detection of the starting by the detecting unit, and a prohibiting unit that prohibits the release of the restraint by the releasing unit until a predetermined time is measured by the measuring unit.
