<p>In a voltage controller for a vehicle, voltage controlling means controls 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 of a field current passing through a field winding of the power generator. This control is performed by operating switching means connected to the field winding so that the switching means is conducted intermittently. Signal generating means generates a power generator state signal by measuring a state of the power generator at predetermined measurement periods. Signal averaging means performs an exponentially weighted averaging of the power generator state signal. The signal averaging means executes the averaging within a predetermined averaging period and updates the averaging at every predetermined measurement period.</p> |
