Abstract:
1. A power generation control apparatus for a vehicle, that controls an output voltage of a vehicle generator mounted on a vehicle by interrupting a current supply to an exciting winding of the vehicle generator, comprising: output voltage detecting means configured to detect an output voltage of the vehicle generator; exciting current detecting means configured to detect an exciting current flowing through the exciting winding; rotation speed detecting means configured to detect a rotation speed of the vehicle generator; torque estimating and exciting current limiting value determining means configured to estimate a generation torque of the vehicle generator based on the output voltage, the exciting current, and the rotation speed detected by the output voltage detecting means, the exciting current detecting means, and the rotation speed detecting means, respectively, and torque estimating and exciting current limiting value determining means configured to further estimate an inertia torque of the vehicle generator based on a change rate of the rotation speed detected by the rotation speed detecting means; and exciting current control means configured to control suppression of the exciting current flowing through the exciting winding so that a change rate of a sum of the generation torque and the inertia torque detected by the torque estimating and exciting current limiting value determining means does not exceed a predetermined value.
