Description
La présente invention est relative à un procédé et à un dispositif pour la coupure d'un démarreur de véhicule automobile après démarrage du moteur thermique de celui-ci.The present invention relates to a method and to a device for switching off a vehicle starter automobile after starting the heat engine thereof.
Habituellement, l'arrêt de l'entraínement d'un moteur thermique par son démarreur est commandé par l'utilisateur du véhicule qui relâche la clé de contact lorsque le moteur thermique fait un bruit caractéristique.Usually, stopping the training of a thermal engine by its starter is controlled by the user of the vehicle who releases the ignition key when the engine makes a characteristic noise.
Toutefois, la tendance à rendre les moteurs thermiques de plus en plus silencieux fait qu'il devient difficile pour l'utilisateur de détecter la fin du démarrage. Il en résulte une sollicitation plus sévère du démarreur.However, the tendency to make engines more and more quiet thermal makes it becomes difficult for the user to detect the end of the start-up. This results in more severe solicitation of the starter.
On connaít déjà de nombreux dispositifs pour couper un démarreur de véhicule automobile lorsque le moteur thermique a démarré et est suffisamment autonome pour atteindre de lui-même son régime de ralenti.We already know many devices for cut a motor vehicle starter when the engine has started and is sufficiently autonomous to reach its idle speed by itself.
En particulier, il a déjà été proposé de commander la coupure du démarreur en comparant la tension de la batterie à une tension de référence, le démarreur étant coupé lorsque la tension de la batterie atteint cette tension de référence.In particular, it has already been proposed to order the starter cut-off by comparing the voltage of the battery at a reference voltage, the starter being cut off when the battery voltage reaches this reference voltage.
Un dispositif mettant en oeuvre une telle commande
a été décrit dans l'introduction de FR 2 626 417.A device implementing such a command
has been described in the introduction to
On sait en effet que lorsqu'un démarreur commence à entraíner un moteur thermique, la tension aux bornes de la batterie subit une brusque diminution du fait du courant important qui circule dans le démarreur. La tension de la batterie retrouve son niveau initial lorsque le moteur thermique a démarré.We know that when a starter starts to drive a heat engine, the voltage across the battery experiences a sudden decrease due to the large current flowing in the starter. The battery voltage returns to its original level when the engine has started.
Toutefois, un tel dispositif n'est pas satisfaisant.However, such a device is not satisfactory.
En particulier, la tension aux bornes de la batterie peut varier considérablement dans le temps, en fonction notamment de son état d'entretien ou de la température ambiante.In particular, the voltage across the battery can vary considerably over time, depending in particular on its state of maintenance or the ambient temperature.
De ce fait, si la tension de la batterie est trop basse, il se peut que le démarreur ne soit pas coupé immédiatement après le démarrage du moteur thermique et fonctionne bien au-delà de la durée qui serait nécessaire.Therefore, if the battery voltage is too high low, the starter may not be cut immediately after starting the engine and works well beyond the time that would be required.
Au contraire, si la tension de la batterie est trop importante, il se peut que le démarreur soit coupé intempestivement, bien avant le démarrage du moteur thermique.On the contrary, if the battery voltage is too large, the starter may be off accidentally, well before the engine starts thermal.
Un but de l'invention est de pallier ces inconvénients.An object of the invention is to overcome these disadvantages.
A cet effet, elle propose un procédé pour la commande de la coupure d'un démarreur de véhicule automobile selon lequel on mesure la tension d'alimentation de ce démarreur et on coupe le démarreur lorsque cette tension atteint une valeur seuil, caractérisé en ce que cette valeur seuil est fonction de la valeur de la tension d'alimentation en début de démarrage.To this end, it proposes a method for the vehicle starter cut-off control automobile according to which the voltage is measured of this starter and we cut the starter when this voltage reaches a threshold value, characterized in that this threshold value is a function of the value of the supply voltage at the start of start-up.
L'invention propose également un dispositif pour la mise en oeuvre de ce procédé.The invention also provides a device for the implementation of this process.
D'autres caractéristiques et avantages de l'invention ressortiront encore de la description qui suit. Cette description est purement illustrative et non limitative. Elle doit être lue en regard des dessins annexés sur lesquels :
- la figure 1 est un schéma d'un dispositif de commande de coupure d'un démarreur conforme à un mode de réalisation possible pour l'invention ;
- la figure 2 est un schéma synoptique sur lequel on a illustré un mode de réalisation possible pour les moyens de commande du dispositif de la figure 1.
- Figure 1 is a diagram of a cut-off control device of a starter according to a possible embodiment for the invention;
- FIG. 2 is a block diagram on which a possible embodiment for the control means of the device in FIG. 1 has been illustrated.
On a illustré sur la figure 1 un dispositif pour la commande de l'alimentation d'un démarreur D. Classiquement, un tel démarreur est un moteur électrique monté entre une borne d'alimentation B+ à la tension de la batterie du véhicule et la masse.FIG. 1 illustrates a device for controlling the supply of a starter D. Conventionally, such a starter is an electric motor mounted between a supply terminal B + at the voltage of the vehicle battery and the mass.
Ce dispositif comporte un contacteur 1 monté entre la borne B+ d'alimentation à la tension de la batterie et le démarreur D.This device comprises a contactor 1 mounted between the terminal B + of supply to the battery voltage and the starter D.
Ce contacteur 1 est un relais actionné par un
bobinage 2. L'une des extrémités de ce bobinage 2 est
reliée à la borne d'alimentation B+. Son autre extrémité
est reliée d'une part à la source d'un transistor MOSFET 3
et d'autre part à un bobinage 5 relié à la masse.This contactor 1 is a relay actuated by a winding 2. One of the ends of this
Le drain du transistor 3 est relié à la borne
d'alimentation B+. Sa grille est reliée à la sortie d'une
unité 4, dont elle reçoit une tension de commande.The drain of
Bien entendu, le transistor 3 pourrait être
remplacé par tout autre type d'interrupteur.Of course,
Dans l'exemple illustré sur ces figures, l'unité 4
génère ladite tension de commande en fonction d'une part
de la tension de la borne d'alimentation B+, et d'autre
part de la position du contacteur actionné par la clé de
contact (contacteur 6).In the example illustrated in these figures, the
Les moyens de commande de l'unité 4 sont
représentés schématiquement sur la figure 2.The control means of the
L'unité 4 comporte des moyens 7 pour mesurer la
tension de la borne B+ d'alimentation du démarreur D
(tension Ubat).The
Il comporte également des moyens 8 pour mémoriser
la tension U0 de cette borne B+ au début du démarrage,
c'est-à-dire lorsque la clé de contact ferme le contacteur
6.It also includes means 8 for memorizing the voltage U 0 of this terminal B + at the start of starting, that is to say when the ignition key closes the
De façon particulièrement préférentielle, la mesure initiale intervient suffisamment tôt pour que la tension U0 corresponde à la tension de la batterie avant toute chute de tension.In a particularly preferred manner, the initial measurement takes place sufficiently early so that the voltage U 0 corresponds to the voltage of the battery before any voltage drop.
La tension de la borne d'alimentation B+ est ensuite mesurée en permanence pendant toute la phase de démarrage.The voltage of the supply terminal B + is then continuously measured throughout the start-up phase.
La tension Ubat ainsi mesurée est comparée par un comparateur 9 à une valeur Uf de fin de démarrage qui est fonction de la valeur de U0.The voltage U bat thus measured is compared by a comparator 9 to a value U f at the end of starting which is a function of the value of U 0 .
Dans un mode de mise en oeuvre avantageux, Uf est tel que Uf = k.U0, avec k inférieur ou égal à 1.In an advantageous embodiment, U f is such that U f = kU 0 , with k less than or equal to 1.
La valeur de k est par exemple choisie en fonction de la tension batterie moyenne en fin de démarrage, pour un niveau donné du moteur thermique.The value of k is for example chosen as a function of the average battery voltage at the end of startup, for a given level of the engine.
Tant que Ubat est inférieur à cette valeur seuil
Uf, le blocage du transistor 3 est inhibé.As long as U bat is less than this threshold value U f , the blocking of
Le transistor 3 étant fermé, le bobinage 2 est
court-circuité et le contacteur 1 est lui-même fermé.The
Lorsque Ubat devient supérieur à Uf, le blocage du
transistor 3 n'est plus inhibé. Le bobinage 2 n'est plus
court-circuité et le contacteur 1 est ouvert. Le démarreur
D est alors coupé.When U bat becomes greater than U f , the blocking of
Bien entendu, les moyens qui constituent l'unité 4
peuvent être soit analogiques, soit numériques.Of course, the means which constitute the
Comme on l'aura compris, la solution proposée par l'invention permet de réduire systématiquement la durée du démarrage au juste nécessaire. En particulier, cette solution permet de s'affranchir des variations de la tension de la batterie et en particulier de celles qui sont dues aux variations de température.As will be understood, the solution proposed by the invention makes it possible to systematically reduce the duration of the start up just right. In particular, this solution overcomes variations in the battery voltage and especially those that are due to temperature variations.
Le confort de l'usager en est amélioré. A terme, il devient possible d'envisager d'alléger ou de simplifier la partie lanceur du démarreur en supprimant la fonction roue libre.User comfort is improved. Ultimately, it becomes possible to consider reducing or simplifying the starter part of the starter by removing the function freewheel.
Par ailleurs, la solution proposée présente l'avantage d'être entièrement autonome et de ne nécessiter aucun câblage supplémentaire lors de l'installation sur le véhicule.In addition, the proposed solution presents the advantage of being entirely autonomous and of not requiring no additional wiring during installation on the vehicle.
L'ensemble constitué par un dispositif de commande du type proposé par l'invention et son alternateur est en effet interchangeable avec un démarreur classique.The assembly constituted by a control device of the type proposed by the invention and its alternator is in interchangeable effect with a conventional starter.
On notera également que le courant au niveau du
contacteur 6 de la clé est d'un niveau très bas : quelques
milliampères au lieu des valeurs habituelles de 10 à 40
ampères. De ce fait, le démarreur proposé par l'invention
peut être traité comme un organe de commande à faible
courant, ce qui permet d'envisager de nombreuses
évolutions de la commande de démarrage, par exemple :
commande par entrée de codes, par la pédale
d'accélération, etc.Note also that the current at the
