Title (EN) VEHICLE ENGINE CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE MOTEUR DE VÉHICULE
(JA) 車両用エンジンの制御装置
Abstract:
(EN) This vehicle engine control device is equipped with: an air intake channel (11); a throttle valve (13); a bypass passage (15) for bypassing the throttle valve (13); an idle speed control valve (14) provided in the bypass passage (15); a rotation speed sensor (32); a throttle sensor (33); a fuel cut means (31); a control means (31) for keeping the engine rotation speed while idling at a pre-set target rotation speed by controlling the aperture of the idle speed control valve (14); and an abnormality determination means (31) for determining that an idling abnormality has occurred, when the throttle aperture is less than or equal to a prescribed first aperture threshold and the fuel cut rotations are greater than or equal to a prescribed rotation threshold within a prescribed time period.
(FR) La présente invention concerne un dispositif de commande de moteur de véhicule doté : d'un canal d'admission d'air (11) ; d'une vanne papillon (13) ; d'un passage de dérivation (15) pour contourner la vanne papillon (13) ; d'une soupape de commande de vitesse de ralenti (14) disposée dans le passage de dérivation (15) ; d'un capteur de vitesse de rotation (32) ; d'un capteur d'étranglement (33) ; d'un moyen de coupure de carburant (31) ; d'un moyen de commande (31) pour maintenir la vitesse de rotation du moteur pendant le ralenti à une vitesse de rotation cible prédéfinie en commandant l'ouverture de la soupape de commande de vitesse de ralenti (14) ; et un moyen de détermination d'anomalie (31) pour déterminer qu'une anomalie de ralenti s'est produite, lorsque l'ouverture d'étranglement est inférieure ou égale à un premier seuil d'ouverture prescrit et que les rotations de coupe de carburant sont supérieures ou égales à un seuil de rotation prescrit pendant une durée prescrite.
(JA) 車両用エンジンの制御装置は、吸気通路(11)と、スロットル弁(13)と、スロットル弁(13)をバイパスするバイパス通路(15)と、バイパス通路(15)に設けられるアイドルスピードコントロール弁(14)と、回転数センサ(32)と、スロットルセンサ(33)と、燃料カット手段(31)と、アイドルスピードコントロール弁(14)の開度を制御することによりアイドル中におけるエンジン回転数を予め設定した目標回転数に維持する制御手段(31)と、エンジン(1)のアイドル中に、スロットル開度が所定の第1開度閾値以下であり、且つ燃料カットの回数が所定時間内で所定の回数閾値以上となるとき、アイドル異常が発生したと判定する異常判定手段(31)とを備える。
