Title
(EN) APPARATUS AND METHOD FOR CALIBRATING AN ENGINE MANAGEMENT SYSTEM
(FR) APPAREIL ET PROCEDE PERMETTANT D'ETALONNER UN SYSTEME DE GESTION DE MOTEUR
Abstract
(EN)
A method and control apparatus for an internal combustion engine that allows an operator to calibrate engine performance relative to an engine operating characteristic. The control apparatus comprises a base engine control map that correlates values of the characteristic with values of a base engine control, a trim control map that correlates the values of the characteristic with values of a trim control, an engine control unit that obtains from the base engine control and trim control maps the respective base engine control and trim control values that are based on the characteristic value, and a panel that is operatively coupled with the engine control unit and includes a first switch regulating a trim signal supplied to the engine control unit. The trim control map is separated from the base control map. The engine control unit calculates an engine operating control value based on the obtained values. The calculated engine operating control value is supplied to the internal combustion engine to vary the engine performance. The first switch is adapted to be manipulated by the operator. And the trim signal causes the engine control unit to modify the trim control values in the trim control map.

La présente invention concerne un procédé et un appareil de contrôle destinés à un moteur à combustion interne qui permet à un opérateur d'étalonner les performances d'un moteur par rapport à des caractéristiques de fonctionnement de ce moteur. Cet appareil de contrôle comprend une table de contrôle de moteur de base qui met en corrélation les valeurs des caractéristiques avec les valeurs d'un contrôle de moteur de base, une table de contrôle de réglage qui met en corrélation les valeurs des caractéristiques avec les valeurs d'un contrôle de réglage, une unité de contrôle de moteur qui obtient des tables de contrôle de moteur et de contrôle de réglage les valeurs de contrôle de moteur de base et de contrôle de réglage respectives fondées sur la valeur des caractéristiques, et un panneau couplé opérationnel avec l'unité de contrôle de moteur et qui comprend un premier commutateur qui régule un signal de réglage fourni à l'unité de contrôle de moteur. La table de contrôle de réglage est séparée de celle du contrôle de base. L unité de contrôle de moteur calcule une valeur de contrôle de fonctionnement du moteur fondée sur les valeurs obtenues. Cette valeur de contrôle de fonctionnement de moteur calculée est fournie au moteur à combustion interne de façon à modifier les performances de ce moteur. Le premier commutateur est adapté pour être manipulé par l'opérateur. Le signal de réglage fait en sorte que l'unité de contrôle de moteur modifie les valeurs de contrôle de réglage dans la table de contrôle de réglage.
