Description
La présente invention concerne un système d'alimentation en gaz comburant d'un moteur à combustion interne de véhicule, comprenant, dans une tubulure d'admission, un papillon d'admission solidaire en déplacement d'un arbre d'un moteur de régulation lui-même solidaire en déplacement d'un organe de commande mécanique et des moyens de détermination du déplacement du moteur, par rapport à une position de repos, sous l'action de commande mécanique, l'organe de commande mécanique commandant directement le déplacement du moteur.The present invention relates to a combustion gas supply system of a vehicle internal combustion engine, comprising, in an intake manifold, an intake throttle integral with the displacement of a shaft of a regulation motor itself integral with the movement of a mechanical control member and means for determining the displacement of the motor, relative to a position of rest, under the action of mechanical control, the mechanical control member directly controlling the movement of the motor.
Dans le cas d'un moteur à essence, la vitesse du moteur est notamment déterminée à partir de la pédale d'accélération, qui agit sur le papillon d'admission.In the case of a petrol engine, the speed of the engine is notably determined at from the accelerator pedal, which acts on the intake throttle.
Pour fonctionner dans des conditions optimales, afin de ne pas caler ou de ne pas polluer exagérément, le moteur doit être alimenté par un mélange d'air et d'essence au débit voulu et restant dans des proportions bien définies.To operate in optimal conditions, so as not to stall or not polluting excessively, the engine must be powered by a mixture of air and gasoline desired flow rate and remaining in well defined proportions.
Or, au ralenti, la mise en route d'un appareil électrique, comme un climatiseur, charge brutalement le moteur, qui risque de caler. Pour y remédier, il est connu de prévoir un circuit supplémentaire d'arrivée d'air. Un calculateur de contrôle de la vitesse du moteur commande, par un moteur pas à pas, un pointeau de réglage du circuit supplémentaire et évite le calage par l'arrivée d'air correspondante.However, at idle, switching on an electrical device, such as an air conditioner, charges suddenly the engine, which could stall. To remedy this, it is known to provide a additional air supply circuit. A speed control computer motor controls, by a stepping motor, a circuit adjustment needle additional and prevents stalling by the corresponding air supply.
Le document FR-A-2 599 805 enseigne un système d'alimentation du type mentionné ci-dessus, dans lequel l'arbre du moteur est solidaire en rotation du papillon et le stator associé est monté rotatif et entraíné par une pédale d'accélération.Document FR-A-2 599 805 teaches a feeding system of the type mentioned above, in which the motor shaft is integral in rotation with the butterfly and the stator associated is rotatably mounted and driven by an accelerator pedal.
Cependant, en cas d'enfoncement ou de relâchement brusque de la pédale d'accélération, le moteur ne peut pas fonctionner dans des conditions optimales.However, if the pedal is suddenly depressed or released acceleration, the engine cannot operate under optimal conditions.
La présente invention vise à résoudre ce problème.The present invention aims to solve this problem.
A cet effet, le système d'alimentation de l'invention est caractérisé par le fait qu'il est prévu un microprocesseur pour comparer cycliquement le déplacement du moteur à un seuil de déplacement de son arbre et du papillon en un laps de temps donné et commander ainsi le déplacement de l'arbre du moteur et donc du papillon pour limiter la vitesse de déplacement de l'arbre en commandant un déplacement complémentaire et progressif de ce dernier. To this end, the supply system of the invention is characterized in that it is provided a microprocessor to cyclically compare the displacement of the motor to a threshold of movement of its tree and the butterfly in a given period of time and thus control the movement of the motor shaft and therefore of the throttle valve to limit the speed of movement of the shaft by controlling a complementary movement and progressive of the latter.
Ainsi, tout déplacement de l'organe de commande qui ferait sortir le moteur de sa plage optimale de fonctionnement est compensé par l'action du moteur de régulation et une commande mécanique d'accélération excessive est transmise au moteur de régulation sous une forme intégrée, c'est-à-dire étalée dans le temps.Thus, any movement of the control member which would bring the engine out of its range optimal functioning is compensated by the action of the regulation motor and a mechanical command of excessive acceleration is transmitted to the regulation motor in an integrated form, that is to say spread over time.
L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée du sytème d'alimentation de l'invention, en référence au dessin annexé, sur lequel :
- la figure 1 est une vue éclatée en perspective du dispositif de l'invention,
- la figure 2 est un diagramme fonctionnel en expliquant le fonctionnement et
- la figure 3 illustre la loi de régulation de la déviation angulaire du papillon.
- FIG. 1 is an exploded perspective view of the device of the invention,
- Figure 2 is a functional diagram explaining the operation and
- FIG. 3 illustrates the law for regulating the angular deviation of the butterfly.
Le système d'alimentation représenté sur la figure 1 est ici monté sur le moteur à
combustion interne d'une voiture et comporte un papillon 1 monté mobile, ici en
rotation, dans une tubulure 2 d'admission d'air d'un carburateur non représenté. Le
papillon 1 est solidaire, en rotation selon un axe 3, de l'arbre 4 d'un moteur 5, pas à pas
dans cet exemple, logé dans un boítier 6 avec un microprocesseur 7 qui le commande
et avec un capteur de déplacement angulaire 8. The power system shown in Figure 1 is here mounted on the motor
internal combustion of a car and comprises a
L'arbre 4 est respectivement porté à ses deux extrémités par deux paliers non
représentés solidaires de la tubulure 2 et porte le boítier 6 en le laissant libre
de tourner autour de l'arbre 4.The
Le capteur de déplacement 8 détermine cycliquement la position angulaire du
boítier 6 par rapport à la tubulure 2 et transmet un signal correspondant au
microprocesseur 7.The
Un câble 11 relie une pédale d'accélération 10 à une extrémité d'une biellette
12 dont l'autre extrémité comporte une calotte sphérique creuse 13 ajustée sur
un téton sphérique 14, excentrique par rapport à l'axe 3, du boítier 6.A cable 11 connects an
A l'arbre 4 du moteur pas à pas 5 est fixé un index radial 15 se déplaçant entre
deux butées 16-17 du boítier 6 et limitant ainsi la plage P (figure 3) de rotation
angulaire de l'arbre 4 par rapport au boítier 6.A
Le fonctionnement du système d'alimentation de l'invention va maintenant être décrit.The operation of the power system of the invention will now be described.
Comme le montre le diagramme de la figure 2, la pédale d'accélération 10
entraíne directement en rotation le boítier 6. La rotation correspondante par
rapport à la tubulure 2 est mesurée par le capteur 8 et la suite de signaux de
mesure correspondants permet au microprocesseur 7 de déterminer l'amplitude
et la vitesse de cette rotation.As the diagram in FIG. 2 shows, the
Le microprocesseur 7 comporte en mémoire une valeur de seuil correspondant
à une valeur maximale admissible DO (figure 3) de variation angulaire de la
position du papillon 1 en un laps de temps TO donné, une fraction de seconde,
valeur qu'il compare cycliquement à l'angle de rotation mesuré du boítier 6. Le
microprocesseur 7 commande alors le moteur pas à pas 5 si la variation
angulaire dépasse la valeur de seuil DO en un temps inférieur à la durée TO,
c'est-à-dire a une amplitude significative et une vitesse excessive.The microprocessor 7 has in memory a corresponding threshold value
at a maximum admissible value DO (FIG. 3) of angular variation of the
position of
Comme le montre la figure 3, dont la courbe 20 représente la déviation
angulaire D du boítier 6 en fonction du temps t, avec une origine des angles
arbitrairement fixée à zéro pour une position initiale de repos, la position
angulaire 21 du papillon 1 est confondue avec la courbe 20 tant que la
déviation angulaire 20 du boítier 6 est inférieure au seuil DO. Après le début de
la variation de l'angle D pour la courbe 20, ce seuil est ici dépassé après une
durée inférieure à la durée TO, si bien que le microprocesseur 7 commande
ensuite le moteur pas à pas 5 pour faire tourner son arbre 4 en sens inverse de
celui du boítier 6 (flèche F1), afin que la rotation du papillon 1 suive une
courbe 22 présentant une pente moindre que celle de la courbe 20 dans sa
partie variable, jusqu'à rejoindre plus tard la courbe 20.As shown in Figure 3, whose
Les courbes 23 et 24, parallèles à la courbe 20 et ici à égale distance de celle-ci,
délimitent la plage P de régulation du moteur 5, définie par les butées 16,
17. La courbe 22 est toujours dans cette plage P, quitte à en suivre
temporairement un bord et à ne pas corriger de façon optimale la déviation du
papillon 1 si la correction à apporter excède la moitié de cette plage P.The
Connaissant la position absolue du papillon 1 dans la tubulure 2 et l'intensité
de la commande mécanique provenant de la pédale 10, on comprendra qu'il
est possible de mémoriser, dans le mircroprocesseur 7, des tables de valeurs
ou des algorithmes permettant d'adapter au mieux la vitesse de rotation du
papillon 1.Knowing the absolute position of the
Entre autres, on peut prévoir de modifier la valeur du seuil angulaire DO, de la
durée TO et de la pente de la courbe 22 en fonction de la position absolue
initiale du papillon 1 et, par exemple, permettre une rotation plus rapide lorsque
le papillon 1 est déjà en position de semi-ouverture de la tubulure 2, donc avec
un moteur de voiture tournant à allure soutenue et ainsi mieux apte à
accélérer.Among other things, provision can be made to modify the value of the angular threshold DO, of the
duration TO and the slope of
Inversement, le capteur 8 de position angulaire absolue pourrait être remplacé
par un détecteur de déplacement relatif, tel qu'un accéléromètre, à partir des
mesures duquel le microprocesseur 7 déterminerait des rotations relatives.Conversely, the absolute
On comprendra que les éléments du système d'alimentation auraient pu avoir des déplacements autres que rotatifs.It will be understood that the elements of the supply system could have displacements other than rotary.
