(EN) CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE POUR UN MOTEUR À COMBUSTION INTERNE
要約
(EN)
A control system of an internal combustion engine is provided with an air flowmeter which is arranged in an engine intake passage, has a transition period from the initial operating state to the end operating state for obtaining the output value of the air flowmeter in the period from the time of startup of the internal combustion engine to when the warmup operation ends, calculates the cumulative air amount in the transition period from the detected output value of the air flowmeter, and uses the calculated cumulative air amount and the reference intake air amount corresponding to the transition period as the basis to correct the output value of the air flowmeter.

(FR)
L'invention concerne un dispositif de commande pour un moteur à combustion interne qui est muni d'un débitmètre d'air situé dans un passage d'admission du moteur. La période de transition entre un état de fonctionnement initial et un état de fonctionnement final pour acquérir la valeur en sortie du débitmètre d'air est fixée dans la période allant du démarrage du moteur à combustion interne à la fin de la période de chauffage. La totalité de la quantité d'air dans la période de transition est calculée à partir de la valeur en sortie détectée du débitmètre d'air, et la valeur en sortie du débitmètre d'air est corrigée sur la base de la totalité de la quantité d'air calculée et de la quantité d'air d'admission de référence correspondant à la période de transition.
