Abstract
The vehicle-use power generation control apparatus regulates an output voltage of a vehicle generator driven by a vehicle engine at a set value by on/off controlling an excitation current flowing through an excitation winding of the vehicle generator The vehicle-use power generation control apparatus includes a rotation detecting circuit detecting a rotational speed of the vehicle generator, and an excitation current control circuit reducing, when the rotation detecting circuit detects decrease of the rotational speed, the excitation current at a rate depending on a rate of the decrease of the rotational speed detected by the rotation detecting circuit.
