IGNITION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE
摘要：
The ECU (40) outputs an ignition signal Si to an ignition apparatus (30) through an ignition communication line (Li), and outputs a discharge waveform control signal Sc with a binary value of "1" through a waveform control communication line (Lc). The ignition apparatus (30) performs the closing operation of the ignition switching element (60), in a period during which the ignition signal Si is input. In an input period of the discharge waveform control signal Sc after the input stop of the ignition signal Si, the ignition apparatus (30) controls the electric current flowing through a primary coil (52), by the opening-closing operation of a control switching element (80). When the voltage of the waveform control communication line Lc still is a binary "1" during an output stop period of the discharge waveform control signal Sc, the ECU (40) determines that the waveform control communication line (Lc) is abnormal, and executes a fail-safe process.
摘要（中）：

ECU（40）通过点火通信线路（Li）向点火装置（30）输出点火信号Si，并通过波形控制通信线路（Lc）输出二进制值“1”的放电波形控制信号Sc ）。 在点火信号Si输入的期间，点火装置（30）进行点火开关元件（60）的闭合动作。 在点火信号Si的输入停止后的放电波形控制信号Sc的输入期间，点火装置（30）通过控制切换的开闭动作来控制流经初级线圈（52）的电流 元件（80）。 在放电波形控制信号Sc的输出停止期间，当波形控制用通信线路Lc的电压为二进制“1”时，ECU（40）判定为波形控制用通信线路（Lc）异常， 一个故障安全的过程。
