Abstract
A vehicle power generating device includes an alternator which has a voltage regulator that keeps the voltage of generated power constant, and an electronic control unit that controls the voltage regulator. In this vehicle power generating device, the alternator has an abnormally high temperature determining portion that determines whether the temperature of the alternator is abnormally high, and an abnormal signal outputting portion which, when it has been determined by the abnormally high temperature determining portion that the temperature of the alternator is abnormally high, outputs a signal indicative of the determination that the temperature is abnormally high to the electronic control unit. Also, when the electronic control unit receives the signal indicative of the determination that the temperature is abnormally high, the electronic control unit controls the voltage regulator such that the voltage generated by the alternator is suppressed.
