An alternator control apparatus is provided which includes a first controller and a second controller that periodically transmits an instruction signal related to electric power generation to the first controller, wherein the instruction signal selectively includes a power generation instruction signal and a non-power generation instruction signal, the first controller, if a detection value of power supply voltage is less than a threshold and receives the power generation instruction signal from the second controller, controls a power generation amount of the alternator to be greater than a predetermined reference, and, if the detection value is less than the threshold and receives the non-power generation instruction signal from the second controller, forms or maintains the non-power generated or the power generation suppressed state, the second controller periodically transmits the non-power generation instruction signal to the first controller until a predetermined condition is met after completion of engine start.
