Method and apparatus for controlling electric power generation for vehicles

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, comprising:

• a restraining unit that restrains electric power generation of the generator in response to a given signal;
• a releasing unit that releases the restraint by the restraining unit when generated voltage of the generator is equal to or less than a first predetermined value;
• 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, wherein
• the restraining unit restrains the electric power generation by limiting an exciting current value of the generator to a value corresponding to the given signal, and
• the releasing unit prohibits the release of the restraint only when a limit value of excitation current of the restraining unit is equal to or less than a third predetermined value.
