Description
La présente invention est relative aux procédés et dispositifs de gestion de la coupure d'un démarreur de véhicule automobile.The present invention relates to methods and starter cut-off management devices of motor vehicle.
Habituellement, la coupure de l'entraínement d'un moteur thermique par son démarreur est commandée par l'utilisateur du véhicule qui relâche la clé de contact lorsque le moteur thermique fait un bruit caractéristique.Usually the cutout of the drive of a heat engine by its starter is controlled by the vehicle user who releases the key contact when the engine makes a noise feature.
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 stress 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 d'un 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 control the shutdown of a starter by comparing the battery voltage at a reference voltage, the starter being cut off when 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 was 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 begins to drive a heat engine, the voltage at battery terminals undergoes a sudden decrease in the makes a large current flowing in the starter. Battery voltage returns to its original level when the engine has started.
Toutefois, un tel dispositif n'est pas complètement satisfaisant.However, such a device is not completely satisfactory.
En particulier, la comparaison à une tension de référence prédéterminée ne permet pas une coupure du démarreur contrôlée de manière assez précise. En outre, 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 comparison to a voltage of predetermined reference does not allow cutting of the starter controlled fairly precisely. In addition, battery terminal voltage may vary considerably over time, depending in particular on its state of maintenance or ambient temperature.
Un but de l'invention est de pallier tout ou partie de ces inconvénients.An object of the invention is to alleviate all or some of these drawbacks.
On connaít déjà par l'abrégé de la demande japonaise JP 03070868 un procédé pour la gestion de la coupure d'un démarreur de véhicule automobile selon lequel on mesure la tension d'alimentation de ce démarreur et on coupe l'alimentation du démarreur lorsque cette tension atteint une valeur seuil.We already know by the abstract of the request Japanese JP 03070868 a process for the management of shutdown of a motor vehicle starter according to which we measure the supply voltage of this starter and the starter power is cut off when this voltage reaches a threshold value.
La solution proposée par l'invention consiste en ce qu'on ouvre une fenêtre temporelle à la fermeture du contacteur du démarreur pendant laquelle on mesure la valeur maximale que prend ladite tension d'alimentation, et en ce qu'on détermine ladite valeur seuil en fonction de la valeur maximale mesurée dans ladite fenêtre temporelle.The solution proposed by the invention consists of what we open a time window when the starter switch during which the maximum value taken by said supply voltage, and in that said threshold value is determined as a function of the maximum value measured in said window time.
Ce procédé est avantageusement complété par les différentes caractéristiques suivantes prises seules ou selon toutes leurs combinaisons techniquement possibles :
- la valeur seuil est une combinaison linéaire de ladite valeur et de la valeur de la tension de l'alimentation avant la commande du démarrage ;
- on ouvre en outre à la fermeture du contacteur du démarreur une deuxième fenêtre temporelle pendant laquelle on mesure la valeur maximale que prend la tension d'alimentation du démarreur et si cette valeur maximale n'est pas supérieure à un seuil déterminé, on considère que le moteur thermique est bloqué ou qu'une vitesse est engagée et on coupe l'alimentation du démarreur ;
- le seuil auquel est comparée la valeur maximale que prend la tension d'alimentation dans cette deuxième fenêtre temporelle, est déterminé en fonction de la valeur maximale que prend la tension d'alimentation dans la première fenêtre temporelle ;
- on ouvre une fenêtre temporelle à la fermeture de l'interrupteur de commande de démarreur, pendant laquelle on mesure la valeur moyenne de la tension d'alimentation de la batterie et si cette valeur est inférieure à un seuil donné, on considère que le contacteur du démarreur est défaillant et on coupe l'alimentation du démarreur ;
- la tension d'alimentation du démarreur est mesurée à travers une diode Zéner ;
- la valeur seuil utilisée pour la coupure du démarreur est fonction de la température de fonctionnement.
- the threshold value is a linear combination of said value and the value of the supply voltage before the start command;
- in addition, when the starter contactor is closed, a second time window is opened during which the maximum value taken by the starter supply voltage is measured and if this maximum value is not greater than a determined threshold, it is considered that the the combustion engine is blocked or a gear is engaged and the starter power is cut off;
- the threshold to which the maximum value taken by the supply voltage in this second time window is compared is determined as a function of the maximum value taken by the supply voltage in the first time window;
- a time window is opened when the starter control switch is closed, during which the average value of the battery supply voltage is measured and if this value is less than a given threshold, the contactor of the starter is faulty and the starter power is cut off;
- the starter supply voltage is measured through a Zener diode;
- the threshold value used for switching off the starter depends on the operating temperature.
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 figures annexées sur lesquelles :
- La figure 1 est un schéma d'un dispositif de gestion de la coupure d'un démarreur conforme à un mode de réalisation possible pour l'invention ;
- la figure 2 est un graphe sur lequel on a porté l'allure de la tension de la batterie au cours d'un démarrage.
- FIG. 1 is a diagram of a device for managing the shutdown of a starter in accordance with a possible embodiment for the invention;
- Figure 2 is a graph on which the shape of the battery voltage was plotted during a start.
On a illustré sur la figure 1 un dispositif pour la commande de l'alimentation d'un démarreur qui comporte un moteur électrique M monté entre une borne d'alimentation B+ à la tension de la batterie du véhicule et la masse. Is illustrated in Figure 1 a device for the control of the supply of a starter which includes an electric motor M mounted between a terminal B + to the battery voltage of the vehicle and 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 B + terminal of supply to the voltage of the battery and starter D.
Ce contacteur 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 is a relay actuated by a
winding 2. One end of this winding 2 is
connected to the power supply terminal B +. Its other end
is connected on the one hand to the source of a
Le drain du transistor 3 est relié à la borne
d'alimentation B+. La grille est reliée à la sortie
d'une unité 4 dont elle reçoit une tension de commande.The drain of
L'unité 4 est par exemple un microprocesseur.
Elle génère la tension de commande en fonction de la
tension de la borne d'alimentation B+ et de la position
d'un interrupteur de démarrage 6, qui est par exemple
une clé de contact.The
L'interrupteur 6 est disposé entre la borne
d'alimentation B+ et une entrée 42 de l'unité 4.
Une entrée 40 de ladite unité 4 est reliée à la
borne B+ par l'intermédiaire d'une diode Zéner 7 qui est
passante de ladite entrée 40 vers ladite borne B+.An
Avantageusement, il est prévu entre la diode Zéner 7 et la borne B+ un filtre de type RC qui permet de filtrer la tension de la batterie pour y supprimer les parasites.Advantageously, it is provided between the diode Zéner 7 and terminal B + an RC type filter which allows to filter the battery voltage to remove it parasites.
Ce filtre est sur la figure 1 constitué par une
résistance R1 montée entre la diode 7 et la borne B+ et
par un condensateur C monté entre le point commun à la
résistance R1 et à la diode 7 et la masse.This filter is in FIG. 1 constituted by a resistor R 1 mounted between the
L'anode de la diode 7 est par ailleurs reliée à
la masse par l'intermédiaire d'une résistance R2, la
tension mesurée à l'entrée 40 étant la tension aux
bornes de cette résistance R2.The anode of
Par ailleurs, la borne B+ d'alimentation est
également reliée à une entrée 41 de l'unité 4 par
l'intermédiaire d'un pont diviseur de tension qui
comprend une résistance R3 et une résistance RT variable
en fonction de la température. Ce montage permet à
l'unité 4 de connaítre la température de fonctionnement
du démarreur.Furthermore, the supply terminal B + is also connected to an
Sur la figure 2, on a appelé Uinit la tension de
la batterie avant que l'interrupteur 6 ne soit fermé.In Figure 2, U init was called the battery voltage before the
Lorsque l'opérateur ferme en un instant t0
l'interrupteur de démarrage 6, l'unité de gestion 4
commande par l'intermédiaire du transistor 3
fonctionnant en interrupteur, le déplacement du
contacteur de puissance 1.When the operator closes the
Ce contacteur de puissance 1 a une double fonction.This power contactor 1 has a double function.
D'une part, il constitue un actionneur linéaire qui déplace le pignon lanceur. D'autre part, il constitue un relais de puissance qui commande l'alimentation du moteur électrique du démarreur.On the one hand, it constitutes a linear actuator which moves the starter gear. On the other hand, constitutes a power relay which controls the starter electric motor supply.
Lorsque le contacteur 1 est déplacé vers sa position de fermeture (phase de déplacement du pignon lanceur vers sa position d'engrenage), la tension de la batterie chute à un premier niveau Udep.When the contactor 1 is moved to its closed position (phase of movement of the starter pinion towards its gear position), the battery voltage drops to a first level U dep .
Puis, lorsque le contacteur 1 atteint sa position de fermeture en un instant t1, le courant circule dans le moteur M et la tension de la batterie chute à nouveau.Then, when the contactor 1 reaches its closed position at an instant t 1 , the current flows in the motor M and the battery voltage drops again.
Tant que le moteur thermique n'est pas démarré, cette tension reste basse. Elle présente des ondulations qui correspondent aux cycles de compression du moteur thermique.As long as the engine is not started, this voltage remains low. It has ripples which correspond to the engine compression cycles thermal.
Lorsque le moteur thermique a démarré, les ondulations disparaissent et la tension de la batterie remonte pour retrouver sa valeur Uinit.When the heat engine has started, the ripples disappear and the battery voltage rises to regain its U init value.
A la fermeture du contacteur de puissance au
temps t1, l'unité de gestion 4 ouvre jusqu'à un temps t2
une fenêtre temporelle pendant laquelle elle mesure la
valeur maximale Uosci que prennent les oscillations de la
tension de la batterie.When the power contactor closes at time t 1 , the
La durée de cette fenêtre temporelle est par exemple de l'ordre de 2 ou 3 secondes.The duration of this time window is by example of the order of 2 or 3 seconds.
Cette valeur Uosci est utilisée avec la valeur initiale de la tension de la batterie Uinit pour déterminer la tension seuil qui, lorsqu'elle est atteinte par la tension de la batterie, déclenche la coupure du démarreur.This value U osci is used with the initial value of the battery voltage U init to determine the threshold voltage which, when reached by the battery voltage, triggers the starter cut-off.
La tension seuil est par exemple une combinaison linéaire de Uinit et Uosci.The threshold voltage is for example a linear combination of U init and U osci .
On notera que la tension Uinit est de l'ordre de 10 à 14 Volts, tandis que la chute de tension Uinit-Uosci est de l'ordre de 4 à 5 Volts.It will be noted that the voltage U init is of the order of 10 to 14 volts, while the voltage drop U init -U osci is of the order of 4 to 5 volts.
Or, les tensions que peuvent mesurer les microprocesseurs usuels sont généralement comprises entre 0 et 5 Volts.However, the tensions that the common microprocessors are generally understood between 0 and 5 Volts.
La diode Zéner 7 permet de ramener la tension de
la batterie à une valeur mesurable en entrée de l'unité
4.The
La tension Zéner de cette diode est par exemple de 7 à 10 Volts.The Zener voltage of this diode is for example from 7 to 10 Volts.
Avantageusement, on utilise comme loi pour
déterminer la tension seuil :
D'autres fonctionnalités peuvent également être prévues.Other features may also be provided.
En particulier, il peut être prévu que si la tension de la batterie n'évolue pas significativement entre le temps t1 de fermeture du contacteur et un temps t3 au bout duquel on pourrait espérer que le moteur thermique soit démarré, le microprocesseur considère que le moteur thermique est bloqué ou qu'une vitesse est engagée, et coupe l'alimentation du démarreur.In particular, it can be provided that if the voltage of the battery does not change significantly between the time t 1 of closing of the contactor and a time t 3 at the end of which it could be hoped that the heat engine is started, the microprocessor considers that the engine is blocked or a gear is engaged, and cuts the power to the starter.
De la même façon, si dans une fenêtre temporelle suivant le temps t0 auquel le conducteur actionne l'interrupteur de démarrage, par exemple en tournant sa clé de contact, la valeur moyenne de tension de la batterie descend au-delà d'un seuil Usdep donné, l'alimentation du démarreur est également coupée.Likewise, if in a time window following the time t 0 at which the driver actuates the start switch, for example by turning his ignition key, the average value of battery voltage drops beyond a threshold U sdep given, the starter power is also cut.
On considère en effet dans ce cas que le
contacteur du démarreur est défaillant, par exemple
qu'il est en position fermée alors qu'il devrait être
ouvert, et qu'il convient de couper l'alimentation du
démarreur afin de protéger son électronique de commande,
ainsi que l'interrupteur 3 qui commande l'alimentation
de la puissance.It is indeed considered in this case that the
starter switch is faulty, for example
that it is in the closed position when it should be
open, and that the power supply to the
starter to protect its control electronics,
as well as
La durée Δt0 de cette fenêtre temporelle est par exemple de l'ordre de 20 ms.The duration Δt 0 of this time window is for example of the order of 20 ms.
Avantageusement, une image de la valeur moyenne
de la tension de la batterie est déterminée en réalisant
la moyenne arithmétique de n échantillons (par exemple
n=4) de la tension sur l'entrée 40 de l'unité de gestion
4, prélevés dans la fenêtre temporelle [t0 ; t0 + Δt0].Advantageously, an image of the average value of the battery voltage is determined by taking the arithmetic average of n samples (for example n = 4) of the voltage on the
