    • A control apparatus for an internal combustion engine, includes: a crankshaft; a crank angle detection unit that outputs a crank signal; a generator that rotates in synchronization with the rotation of the crankshaft, and that outputs alternating voltage signals with one-phase; and a control unit, to which the alternating voltage signals are input, that ascertains ignition timings based on the crank signals, performs ignition control so as to spark the internal combustion engine at the ignition timings, determines a polarity of the alternating voltage signal each time the crank signal is detected, ascertains a polarity cycle of the alternating voltage signals based on the determination result of the polarity, and determines that a failure has occurred in the generator when the polarity cycles do not continuously coincide multiple times with the polarity cycles at the time of forward rotation of the crankshaft.
    • 一种内燃机的控制装置,包括:曲轴; 曲柄角检测单元,其输出曲柄信号; 与曲轴的旋转同步地旋转并且以一相输出交流电压信号的发电机; 以及输入交流电压信号的控制单元,其基于曲柄信号确定点火正时,执行点火控制,以便在点火正时触发内燃机,每次确定交流电压信号的极性 检测曲柄信号,根据极性的判断结果确定交流电压信号的极性周期,并且当极性周期不与极性周期的极性周期连续重合多次时,确定发生器发生故障 曲轴正转时间。
