A vehicle power generation voltage control apparatus is obtained, which has improved reliability, when in a faulty condition, of controlling an exciting current flowing through a field winding even if a monitor and detection circuit becomes faulty. An output voltage of a vehicle power generator or a battery terminal voltage connected to the vehicle power generator is detected by plural monitor and detection circuits, and according to the output of the plural monitor and detection circuits, an exciting current flowing through a field winding of the vehicle power generator is switched on and off, to control the output voltage of the vehicle power generator or the battery terminal voltage connected to the vehicle power generator to be a target voltage. |
