ABSTRACT:
In a generator control apparatus for a vehicle, the control apparatus includes an engine; an intake air temperature sensing section configured to sense a temperature of intake air of the engine; an engine startup temperature-state determining section configured to determine whether the engine is in warm-up state, at the time of startup of the engine; a battery; a battery liquid temperature estimating section configured to estimate a liquid temperature of the battery; a battery liquid temperature storing section configured to store the battery liquid temperature estimated by the battery liquid temperature estimating section; and a generator configured to charge the battery in accordance with the estimated battery liquid temperature. Moreover, in this control apparatus, the battery liquid temperature estimating section is configured to estimate, at the time of engine startup in warm-up state, the battery liquid temperature to be the lower one of the sensed intake air temperature and a battery liquid temperature previously stored by the battery liquid temperature storing section, by comparing the sensed intake air temperature with the previously stored battery liquid temperature.
