    • In order to accurately detect an abnormal state of a rotation direction detection unit for detecting a rotation direction of a crank shaft, provided is an internal combustion engine control apparatus including: a rotation detection unit including the rotation direction detection unit for detecting the rotation direction of the crank shaft of an engine to output a rotation direction signal, and a rotation speed detection unit for outputting a pulse signal according to a rotation speed of the crank shaft; a stop position calculation unit for calculating, based on an output from the rotation detection unit, a stop position of the crank shaft when the engine stops; and an abnormal state detection unit for detecting the abnormal state of the rotation direction detection unit when an actual rotation direction of the crank shaft differs from the rotation direction of the crank shaft based on the rotation direction signal.
    • 为了精确地检测用于检测曲轴的旋转方向的旋转方向检测单元的异常状态,提供了一种内燃机控制装置,包括:旋转检测单元,包括:旋转方向检测单元,用于检测曲轴的旋转方向 用于输出旋转方向信号的发动机的曲轴;以及转速检测单元,用于根据曲轴的转速输出脉冲信号; 停止位置计算单元,用于基于来自所述旋转检测单元的输出,计算当所述发动机停止时所述曲轴的停止位置; 以及异常状态检测单元,用于当曲轴的实际旋转方向与曲轴的旋转方向基于旋转方向信号不同时,检测旋转方向检测单元的异常状态。
