摘要： An engine control device capable of accurately detecting the missing of crank pulses and the erroneous detection of the crank pulses due to generation of noise, wherein a tooth-less part on the outer periphery of a toothed crankshaft for feeding the crank pulses, the erroneous detection of the crank pulses is detected by using the instantaneous value of the rotational speed of the crankshaft calculated by using the crank pulses from the tooth-less part and the teeth across the tooth-less part, and since the instantaneous value of the rotational speed of the crankshaft calculated by using the crank pulses is suddenly decreased and then suddenly increased when the crank pulses are less detected erroneously, the number of the crank pulses less detected is detected by using the number of the crank pulses during that time and, since the instantaneous value of the rotational speed of the crankshaft is suddenly increased and then suddenly decreased when the number of the crank pulses is more detected erroneously, the number of the crank pulses more detected is detected by using the number of the crank pulses during that time.
摘要翻译：本发明提供一种发动机控制装置，该发动机控制装置能够高精度地检测曲轴脉冲的丢失和由于噪音的产生而产生的曲轴脉冲的错误检测，其中，在齿形曲轴的外周上的用于提供曲轴脉冲的无齿部分，错误检测通过使用通过使用来自无齿部分和无齿部分上的齿的曲柄脉冲计算出的曲轴转速的瞬时值来检测曲轴脉冲的转速，并且由于转速的瞬时值通过使用曲柄脉冲计算出的曲轴在错误地检测到较少的曲柄脉冲时突然减小然后突然增加，通过使用在那段时间内的曲柄脉冲的数量来检测较少检测到的曲柄脉冲的数量，并且由于瞬时当曲柄脉冲的数量多时，曲轴的转速值突然增加然后突然降低通过使用在那段时间内的曲柄脉冲的数量来检测更多检测到的曲柄脉冲的数量。

摘要： There is provided an engine start control method and an engine start control apparatus which can judge cell starting and kick starting with a simple constitution to perform optimum engine start according the respective starting. The engine start control method and the engine start control apparatus have a cell starting program at the time when an engine is started by a cell motor and a human power starting program at the time when the engine is started by a human power, detect a difference between a battery voltage at the time of engine stop and a battery voltage at the time of commencement of engine start, and starts the engine in accordance with the cell starting program if this difference is larger than a predetermined value and starts the engine in accordance with the human power starting program if the difference is smaller than the predetermined value.
