Title
(EN) INTERNAL COMBUSTION ENGINE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の制御装置
Abstract
(EN)
An internal combustion engine control device provided with an output current abnormality signal retention unit (112) which determines whether or not a current abnormality signal is output from a current abnormalityity detection unit (108, 110) continuously for a predetermined period or longer, and outputs the current abnormality signal when the current abnormality signal is output continuously for the predetermined period or longer and does not output the current abnormality signal when the current abnormality signal is output continuously for a period shorter than the predetermined period, wherein the current abnormality detection unit (108, 110) compares a current value detected by a current detection unit (R1, R2) with a predetermined threshold value and outputs the current abnormality signal when the current value is equal to or lower than the predetermined threshold value.
(FR)
L'invention concerne un dispositif de commande de moteur à combustion interne pourvu d'une unité de rétention de signal d'anomalie de courant de sortie (112) qui détermine si un signal d'anomalie de courant est émis en sortie par une unité de détection d'anomalie de courant (108, 110) de façon continue pendant une durée prédéterminée ou davantage, et émet en sortie le signal d'anomalie de courant lorsque ledit signal est émis de façon continue pendant la durée prédéterminée ou davantage et n'émet pas en sortie le signal d'anomalie de courant lorsque ledit signal est émis de façon continue pendant une durée inférieure à la durée prédéterminée, l'unité de détection d'anomalie de courant (108, 110) comparant une valeur de courant détectée par une unité de détection de courant (R1, R2) avec une valeur seuil prédéterminée et émettant en sortie le signal d'anomalie de courant lorsque la valeur de courant est égale ou inférieure à la valeur seuil prédéterminée.
(JA)
 内燃機関の制御装置は、電流検出部(R1、R2)により検出された電流値と所定の閾値とを比較し、電流値が所定の閾値以下である場合に電流異常信号を出力する電流異常検出部(108、110)から、電流異常信号が所定時間以上継続して出力されているか否かを判別し、電流異常信号が所定時間以上継続して出力されている場合には電流異常信号を出力すると共に、電流異常信号が所定時間未満継続して出力された場合には電流異常信号を出力しない出力電流異常信号保持部(112)を備える。
