Title (EN) ENGINE CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE D'UN MOTEUR
Abstract: front page image
(EN)In an electronic throttle control system, a target intake pipe pressure as well as a presumed value for the intake pipe pressure is calculated, so that a deviation between the target value and the presumed value for the intake pipe pressure is calculated. The deviation is compensated in an advancing side by an amount corresponding to a delay of response in the throttle control system. An intake air amount passing through a throttle valve is calculated based on the above compensated deviation and a presumed intake air amount. A target opening degree of a throttle valve is finally calculated based on the above-calculated intake air amount passing through a throttle valve. Accordingly, a response and stability of the throttle control can be improved.
(FR)Dans un système électronique de commande des gaz, on calcule la valeur cible de la pression dans le collecteur d'admission, puis on calcule la valeur présumée de la pression dans le collecteur d'admission, ce qui permet de calculer la déviation entre les deux pressions laquelle est compensée dans le sens de l'avance d'une quantité correspondant au retard de la réponse du système de commande des gaz. La quantité d'air d'admission traversant le papillon des gaz se calcule en fonction de la susdite déviation et de la quantité présumée d'air d'admission. Les degrés cible d'ouverture du papillon des gaz se calculent finalement en fonction de la quantité d'air d'admission calculée ci-dessus traversant le papillon des gaz. On obtient ainsi une réponse et une stabilité améliorées de la commande de gaz.
