Description
La présente invention concerne un système de détermination de la quantité de carburant rajoutée dans un réservoir de véhicule automobile, lors d'une opération de remplissage de celui-ci. The present invention relates to a system for determining the amount of fuel added to a tank of a motor vehicle, during a filling operation thereof.
On connaît<B>déjà,</B> dans l'état de la technique, des systèmes de ce type qui comportent des moyens<B>à</B> commutateur de détection de la présence/absence d'un bouchon en position d'obturation d'un orifice de remplissage du réservoir, des moyens<B>à</B> résistance variable<U>de</U> mesure du niveau de carburant dans le ré servoir et des moyens de raccordement de ces moyens de détection et de me sure<B>à</B> des moyens de détermination de la quantité de carburant rajoutée dans le réservoir, par détermination de la différence de niveau de carburant dans le ré servoir après retrait et remise en position d'obturation du bouchon. Already known <B> already, </ B> in the state of the art, systems of this type which include means <B> to </ B> switch detection of the presence / absence of a plug in position shutter of a tank filling orifice, means <B> to </ B> variable resistance <U> of </ U> measurement of the fuel level in the tank and means of connection of these means of detecting and measuring <B> to </ B> means for determining the amount of fuel added to the tank, by determining the difference in fuel level in the tank after removal and return to the closed position of the fuel tank. plug.
De tels systèmes ont par exemple été développés dans le cadre la dépollution des moteurs Diesel de véhicules automobiles pour lesquels un additif doit être injecté dans le réservoir pour abaisser la température de combustion des suies piégées dans un filtre<B>à</B> particules intégré dans la ligne d'échappement du moteur. Such systems have for example been developed in the context of the depollution of diesel engines of motor vehicles for which an additive must be injected into the tank to lower the combustion temperature of soot trapped in a filter <B> to </ B> particles integrated in the engine exhaust line.
La quantité d'additif<B>à</B> rajouter est alors déterminée en fonction la quantité de carburant rajoutée dans le réservoir. The amount of additive <B> to </ B> add is then determined according to the amount of fuel added to the tank.
De façon classique, le retrait du bouchon active un réseau interne du véhicule qui surveille alors l'évolution du niveau de carburant dans le réservoir et en mesurant ce niveau peu avant l'ouverture et peu après la fermeture de celui- ci, en déduit la quantité de carburant rajoutée et donc la quantité d'additif in jecter dans le réservoir. Conventionally, the removal of the cap activates an internal network of the vehicle which then monitors the evolution of the fuel level in the tank and by measuring this level shortly before opening and shortly after closing it, deduces the amount of fuel added and therefore the amount of additive injected into the tank.
Les moyens<B>à</B> commutateur de détection de la présence/absence du bouchon en position d'obturation servent également<B>à</B> déclencher la signalisa tion, au tableau de bord du véhicule, de l'état d'ouverture ou de fermeture ce réservoir pour attirer par exemple l'attention du conducteur du véhicule sur un défaut d'obturation du réservoir.<B>-</B> Dans l'état de la technique, deux circuits séparés sont utilisés pour relier d'une part, les moyens<B>à</B> commutateur de détection et, d'autre part, les moyens<B>à</B> résistance variable de mesure de niveau, aux moyens de détermina tion de la quantité de carburant rajoutée. Ceci necessite donc l'utilisation de quatre fils de raccordement entre ces moyens de mesure et de détection et les moyens de détermination. The means <B> to </ B> switch for detecting the presence / absence of the cap in the closed position also serve <B> to </ B> trigger the signaling, on the dashboard of the vehicle, of the state of opening or closing this tank to attract for example the attention of the driver of the vehicle on a fault filling of the tank. <B> - </ B> In the state of the art, two separate circuits are used to connect on the one hand, the means <B> to </ B> detection switch and, on the other hand, the means <B> to </ B> variable resistance level measurement, to the means of determination of the amount of fuel added. This therefore requires the use of four connection wires between these measuring and detection means and the determination means.
Le but l'invention est de simplifier cette structure. The purpose of the invention is to simplify this structure.
<B>A</B> cet effet, l'invention a pour objet un système de détermination de la quantité de carburant rajoutée dans un réservoir de véhicule automobile, lors d'une opération remplissage de celui-ci, du type comportan t des moyens<B>à</B> commutateur de détection de la présence/absence d'un bouchon en position d'obturation d'un orifice de remplissage du réservoir, des moyens<B>à</B> résistance variable de mesure du niveau de carburant dans le réservoir et des moyens de raccordement ces moyens de détection et de mesure<B>à</B> des moyens de<B>dé-</B> termination de quantité de carburant rajoutée dans le réservoir, par détermina tion de la différence de niveau de carburant dans le réservoir après retrait et re mise en position d'obturation du bouchon, caractérisé en ce une résistance ballast est connectée en série avec les moyens<B>à</B> commutateur détection, en ce que cette résistance ballast et ces moyens<B>à</B> commutateur sont raccordés en parallèle sur moyens<B>à</B> résistance variable de mesure de niveau et en ce que les moyens raccordement comprennent deux fils de raccordement sur les quels transitent les informations de présence/absence du bouchon en position d'obturation et niveau de carburant. For this purpose, the subject of the invention is a system for determining the quantity of fuel added to a tank of a motor vehicle, during a filling operation thereof, of the type comprising means <B> to </ B> switch for detecting the presence / absence of a plug in the closed position of a tank filling orifice, means <B> to </ B> variable resistance of measurement of the fuel level in the tank and means of connection these means of detection and measurement <B> to </ B> means <B> de - </ B> determination of the amount of fuel added to the tank, by determina tion of the fuel level difference in the reservoir after removal and re-closing of the plug, characterized in that a ballast resistor is connected in series with the means <B> to </ B> switch detection, in that that this ballast resistor and these means <B> to </ B> switch are connected in Parallel means <B> to </ B> variable resistance level measurement and in that the connection means comprise two connecting son on which transit the presence / absence information of the plug in the closed position and fuel level .
L'invention sera mieux comprise<B>à</B> la lecture de la description qui va suivre, donnée uniquement<B>à</B> titre d'exemple et faite en se référant aux dessins annexés, sur lesquels<B>:</B> <B>-</B> la<B>1</B> représente un schéma synoptique illustrant structure d'un système d'injection d'additif dans un réservoir de carburant véhicule auto- mobile; _ la 2 représente un schéma synoptique illustrant raccordement de moyens de détection de la position d'un bouchon d'obturation réservoir et de moyens de mesure du niveau de carburant dans celui-ci<B>à</B> moyens de traitement d'informations, selon l'état de la technique; et la<B>3</B> représente un schéma synoptique illustrant raccordement de moyens de detection de la position d'un bouchon d'obturation réservoir et de moyens de mesure du niveau de carburant dans celui-ci<B>à</B> moyens de traitement d'informations, selon l'invention. On a en effet représenté, sur la figure<B>1,</B> un système d'injection d'addi tif dans un réservoir de carburant d'un véhicule automobile. The invention will be better understood by reading the description which will follow, given only by way of example and with reference to the appended drawings, in which <B> to </ B> >: <B> - <B> 1 </ B> represents a schematic diagram illustrating the structure of an additive injection system in a motor vehicle fuel tank; _ 2 represents a block diagram illustrating connection of means for detecting the position of a tank closure cap and means for measuring the fuel level in it <B> to </ B> means of treatment of information, according to the state of the art; and the <B> 3 </ B> represents a block diagram illustrating connection of means for detecting the position of a tank plug and means for measuring the level of fuel therein <B> to </ B> information processing means, according to the invention. In FIG. 1, an injection system has been shown in a fuel tank of a motor vehicle.
Ce réservoir est désigné par la référence générale<B>1</B> sur cette figure et comporte un orifice de remplissage obturé par un bouchon 2. This tank is designated by the general reference <B> 1 </ B> in this figure and comprises a filling orifice closed by a plug 2.
bouchon 2 est associé<B>à</B> des moyens<B>à</B> commutateur détection de la présence/absence de ce bouchon en position d'obturation l'orifice de remplissage réservoir, ces moyens étant désignés par la référence générale <B>3.</B> plug 2 is associated with <B> to </ B> means <B> to </ B> switch detection of the presence / absence of this plug in the closed position of the tank filling orifice, these means being designated by the general reference <B> 3. </ B>
plus, le réservoir est associé<B>à</B> des moyens 4<B>à</B> résistance variable de mesure niveau de carburant dans le réservoir. more, the tank is associated with <B> to </ B> means 4 <B> to </ B> variable resistance measuring fuel level in the tank.
réservoir est également associé<B>à</B> des moyens d'injection<B>5</B> d'addi tif dans le réservoir, raccordés<B>à</B> un réservoir d'additif<B>6.</B> tank is also associated <B> with <B> 5 </ B> injection devices in the tank, connected <B> to </ B> an additive tank <B> 6. </ B>
différents moyens de détection, de mesure et d'injection sont rac cordés<B>à</B> une unité centrale de traitement d'informations désignée la réfé rence générale<B>7,</B> qui comporte un calculateur<B>8</B> relié par des ports<B>10</B> et<B>Il</B> aux différents moyens décrits précédemment. various detection, measurement and injection means are connected to a central information processing unit designated as general reference, which includes a calculator <B> > 8 </ B> connected by ports <B> 10 </ B> and <B> Il </ B> to the various means described above.
conçoit alors que ce calculateur<B>8</B> est adapté pour déterminer la quantité de carburant rajoutée dans le réservoir du véhicule lors d'une opération de remplissage<B>à</B> partir de la différence de niveau de carburant dans réservoir après retrait remise en position d'obturation du bouchon. then conceives that this calculator <B> 8 </ B> is adapted to determine the amount of fuel added to the tank of the vehicle during a filling operation <B> to </ B> from the difference in fuel level in the reservoir after removal to the closed position of the cap.
Le calculateur<B>8</B> est en effet adapté pour détecter une opération de remplissage du réservoir lorsque le bouchon d'obturation 2 est retiré sa posi tion d'obturation et pour détecter la fin de cette opération de remplissage lorsque le bouchon est remis en position d'obturation. The calculator <B> 8 </ B> is in fact adapted to detect a filling operation of the tank when the blanking plug 2 is removed from its sealing position and to detect the end of this filling operation when the plug is returned to the closed position.
La différence entre les niveaux avant et après cette opération de rem plissage permet alors d'avoir la quantité de carburant rajoutée lors cette<B>opé-</B> ration, afin d'injecter la quantité d'additif correspondante. The difference between the levels before and after this filling operation then makes it possible to have the quantity of fuel added during this operation, in order to inject the corresponding quantity of additive.
Comme on l'a indiqué précédemment, dans l'état de la technique, les moyens de détection et les moyens de mesure sont raccordés par circuits séparés<B>à</B> l'unité de traitement d'informations. As previously indicated, in the state of the art, the detection means and the measurement means are connected by separate circuits <B> to </ B> the information processing unit.
Cette structure est illustrée'sur la figure 2, où l'on voit en effet que l'unité centrale<B>7</B> est reliée aux moyens<B>3 à</B> commutateur de détection de la pré- sence/absence du bouchon en position d'obturation par deux fils de raccorde- ment, et aux moyens 4<B>à</B> résistance variable de mesure du niveau de carburant dans le réservoir par deux autres fils de raccordement. This structure is illustrated in FIG. 2, in which it can be seen that the central unit <B> 7 </ B> is connected to the means <B> 3 to the </ B> detection switch of the present invention. the presence / absence of the plug in the closed position by two connecting wires, and means 4 <B> to </ B> variable resistor for measuring the level of fuel in the tank by two other connection wires.
On a représenté sur la figure<B>3</B> un système selon l'invention dans quel l'unité centrale de traitement d'informations<B>7</B> est reliée par un port unique 12 aux moyens<B>à</B> commutateur<B>3</B> et aux moyens<B>à</B> résistance variable 4. FIG. 3 shows a system according to the invention in which the central information processing unit <B> 7 </ B> is connected by a single port 12 to the means <B > to </ B> switch <B> 3 </ B> and to means <B> to </ B> variable resistor 4.
Deux fils de raccordement sont alors utilisés pour raccorder ces diffe- rents moyens. Two connecting wires are then used to connect these different means.
<B>A</B> cet effet, une résistance ballast<B>13</B> est connectée en série avec les moyens<B>à</B> commutateur de détection<B>3</B> et ces moyens<B>à</B> commutateur<B>3</B> et cette résistance<B>13</B> sont raccordés en parallèle sur les moyens<B>à</B> résistance variable 4 de mesure de niveau. <B> A </ B> this effect, a <B> 13 </ B> ballast resistor is connected in series with the <B> <B> 3 </ B> sense <B> and <B> means <B> to </ B> switch <B> 3 </ B> and this resistance <B> 13 </ B> are connected in parallel on the means <B> to </ B> variable resistor 4 to measure level.
Les moyens de raccordement comprennent alors uniquement deux fils de raccordement 14 et<B>15</B> sur lesquels transitent les informations de - sence/absence du bouchon en position d'obturation et de mesure de niveau. The connection means then comprise only two connection wires 14 and <B> 15 </ B> on which the information of - presence / absence of the plug in the closed position and level measurement pass.
<B>A</B> titre d'exemple, la résistance ballast<B>13</B> peut avoir une valeur de l'ordre de<B>15</B> Ohms et la résistance variable 4 peut avoir une valeur variant entre <B>50</B> Ohms pour un réservoir plein et 400 Ohms pour un réservoir vide. <B> A </ B> As an example, the ballast resistance <B> 13 </ B> may have a value of the order of <B> 15 </ B> Ohms and the variable resistor 4 may have a value between <B> 50 </ B> Ohms for a full tank and 400 Ohms for an empty tank.
Lorsque le bouchon d'obturation 2 est retiré de l'orifice de remplissage du réservoir, le commutateur<B>3</B> se ferme et la résistance du circuit associé port 12 passe alors d'une valeur comprise entre<B>50</B> et 400 Ohms<B>à</B> une valeur' comprise entre<B>11,5</B> et 14,5 Ohms. When the blanking plug 2 is removed from the tank fill port, the <B> 3 </ B> switch closes and the resistance of the associated port circuit 12 then changes from a value of <B> 50 </ B> and 400 Ohms <B> to </ B> a value 'between <B> 11.5 </ B> and 14.5 Ohms.
Cette variation de résistance aux bornes du port 12, c'est-à-dire entre les deux fils de raccordement 14 et<B>15,</B> est interprétée par le calculateur comme une ouverture du réservoir et celui-ci engage alors une procédure de lecture du niveau de carburant avant remplissage. This variation of resistance across the terminals of the port 12, that is to say between the two connecting wires 14 and <B> 15, </ B> is interpreted by the computer as an opening of the tank and the latter then engages a procedure for reading the fuel level before filling.
Après la remise en position du bouchon d'obturation, c'est-à-dire après une opération de remplissage du réservoir, la résistance aux bornes du port 12 passe<B>à</B> nouveau<B>à</B> une valeur comprise entre<B>50</B> et 400 Ohms et le calculateur en déduit que le bouchon est remis en position d'obturation pour déclencher une étape d'acquisition du niveau de carburant après cette opération de remplissage et en déduire la quantité de carburant rajoutée lors de cette opération de rem plissage par calcul de la différence entre les niveaux de carburant avant et après cette opération de remplissage, de façon<B>à</B> déterminer la quantité d'additif<B>à</B> ra jouter dans réservoir. After resetting the blanking plug, that is to say after a filling operation of the tank, the resistance across the terminals of the port 12 goes <B> to </ B> again <B> to </ B > a value between <B> 50 </ B> and 400 Ohms and the computer deduces that the cap is returned to the closed position to trigger a step of acquiring the fuel level after this filling operation and deduce therefrom the quantity of fuel added during this filling operation by calculating the difference between the fuel levels before and after this filling operation, so as <B> to </ B> determine the quantity of additive <B> to </ B> Add a tank.
notera également qu'une fonction de diagnostic du fonctionnement de ce systeme peut être réalisée sur ces fils de raccordement 14<B>15</B> et le port 12 par analyse de la résistance présentée qui doit être comprise entre<B>11,5</B> et 400 Ohms. note also that a diagnostic function of the operation of this system can be performed on these connection wires 14 <B> 15 </ B> and port 12 by analysis of the resistance presented which must be between <B> 11, 5 </ B> and 400 Ohms.
n'est pas le cas, un-fil peut être en court-circuit<B>à</B> masse pour une valeur inférieure ou coupé pour une valeur supérieure, en tenant compte des tolérances habituelles. this is not the case, a wire can be short-circuited <B> to </ B> ground for a lower value or cut to a higher value, taking into account the usual tolerances.
conçoit alors qu'une telle structure présente un certain nombre d'avantages, notamment au niveau de la réduction du nombre de fils de raccor dement utilisés. then conceives that such a structure has a number of advantages, particularly in terms of reducing the number of connection wires used.
de soi bien entendu que d'autres modes de réalisation encore de ce système peuvent être envisagés.Of course, other embodiments of this system can be envisaged.
