<p>PURPOSE:To prevent a battery voltage from decreasing very much while lowering a generated voltage to enhance acceleration performance under a condition that a power supply voltage is sufficiently high. CONSTITUTION:There are provided a means 2 for controlling a generation voltage of a generator 1 based on operational conditions, a means 3 for accumulating times T1 during which an instruction value of lowering the generation voltage is output, a means 4 for accumulating times T2 during which an instruction value of not lowering the generation voltage is output, a means 5 for comparing an accumulation time difference T2-T1 with a reference value, and a means 6 for prohibiting output of the instruction value of lowering the generation voltage if the accumulation time difference T2-T2 is not less than the reference value.</p> |
