1. A voltage controller for a vehicle comprising:

  • a voltage controlling means for controlling an output voltage of a power generator mounted on the vehicle and a terminal voltage of a battery connected to the power generator, by controlling a field current passing through a field winding of the power generator by operating a switching means connected to the field winding so that the switching means is conducted intermittently;

    a signal generating means for generating a power generator state signal by measuring a state of the power generator at a predetermined measurement period; and

    a signal averaging means for performing an exponentially weighted averaging of the power generator state signal generated by the signal generating means wherein the signal averaging means executes the averaging within a predetermined averaging period and updates the averaging at the every predetermined measurement period.
