Abstract

The starter contactor has power contacts (1a) connecting current to the starter motor and a winding (2,3) which controls displacement of the power contact. One of these windings is connected between the supply terminal of the battery and the electric motor (M). The control is provided by microprocessor (5) driving a power MOSFET (4) which controls current in one of the windings (2,3). The microprocessor receives a measure of voltage at a point between the motor and the windings, and blocks the transistor, releasing the power contacts, if within a set time after operation of the starter switch the volt the voltage at a point between the winding and the motor is not above a set level.

Description

La présente invention est relative aux dispositifs pour la commande d'un contacteur de démarreur de véhicule automobile.The present invention relates to devices for controlling a vehicle starter switch automobile.

On a illustré sur la figure 1 un démarreur D, qui comporte un moteur électrique M monté entre une borne B+ d'alimentation à la tension de la batterie et la masse.Illustrated in Figure 1 a starter D, which includes an electric motor M mounted between a terminal B + power supply to battery voltage and ground.

L'alimentation du moteur électrique est commandée par un contacteur 1 monté entre ladite borne B+ et le moteur M.Electric motor supply is controlled by a contactor 1 mounted between said terminal B + and the motor M.

Ce contacteur 1 est un relais qui comporte un noyau plongeur (non représenté) actionné par un bobinage d'appel 2 et un bobinage de maintien 3 pour pousser et maintenir en position de fermeture un contact de puissance 1a.This contactor 1 is a relay which includes a plunger core (not shown) actuated by a winding call 2 and a holding coil 3 for pushing and maintain a power contact in the closed position 1a.

Le bobinage d'appel 2 est monté entre l'extrémité du moteur M qui est opposée à la masse et le bobinage 3, ledit bobinage 3 étant relié à la masse par son extrémité opposée.The call winding 2 is mounted between the end of the motor M which is opposite to the ground and the winding 3, said coil 3 being connected to ground by its end opposite.

A leur extrémité commune, les bobinages 2 et 3 sont reliés à la source d'un transistor 4 dont le drain est relié à la borne B+, par l'intermédiaire de l'interrupteur de clé de contact 6.At their common end, the coils 2 and 3 are connected to the source of a transistor 4 whose drain is connected to terminal B +, via the ignition key switch 6.

Ce transistor 4 est commandé, par exemple en tout ou rien, par un microprocesseur 5 - également relié à la borne d'alimentation B+ - qui injecte une tension de commande sur la grille du transistor 4. Ce microprocesseur 5 est par exemple, ainsi qu'illustré sur la figure 1, intégré avec le relais 1 et le transistor 4 à l'intérieur de la carcasse du démarreur. Il peut également être disposé hors du démarreur, en un endroit quelconque du véhicule.This transistor 4 is controlled, for example in all or nothing, by a microprocessor 5 - also connected to the supply terminal B + - which injects a voltage of control on the gate of transistor 4. This microprocessor 5 is for example, as illustrated in FIG. 1, integrated with relay 1 and transistor 4 inside of the starter housing. It can also be located outside the starter, anywhere in the vehicle.

Lorsque ledit transistor 4 devient passant, la bobine d'appel 2 et la bobine de maintien 3 sont alimentées simultanément.When said transistor 4 turns on, the take-up coil 2 and holding coil 3 are powered simultaneously.

Pour permettre une force d'appel importante, la bobine d'appel 2 est choisie avec une résistance très inférieure à celle de la bobine de maintien 3. La résistance du moteur électrique M à l'arrêt étant négligeable par rapport à la résistance des bobinages 2 et 3, l'intensité qui passe dans ledit transistor 4 est maximale tant que le contacteur 1 n'est pas fermé. Ceci produit un échauffement important et rapide du transistor 4.To allow a significant appeal force, the call coil 2 is chosen with very resistance lower than that of the holding coil 3. The resistance of electric motor M at standstill negligible compared to the resistance of the windings 2 and 3, the intensity which passes through said transistor 4 is maximum as long as contactor 1 is not closed. This produces a significant and rapid heating of the transistor 4.

Les forces développées par les bobines 2 et 3 du contacteur mettent en mouvement le noyau plongeur qui, en fin de course, ferme le contact de puissance 1a.The forces developed by coils 2 and 3 of contactor set in motion the plunger core which, in limit switch, closes power contact 1a.

Le point - référencé par 7 - entre la bobine 2, le moteur M et le contact la se trouve alors porté au potentiel du B+. La bobine 2 ne consomme alors pratiquement plus de courant puisque ses deux extrémités sont très voisines de la tension d'alimentation de la borne B+.The point - referenced by 7 - between coil 2, the motor M and the contact is then brought to the potential of B +. Coil 2 then only consumes practically more current since its two ends are very close to the supply voltage of the terminal B +.

Le transistor 4 n'alimentant plus que la bobine de maintien 3, dont la consommation en courant est faible, l'échauffement dudit transistor 4 se trouve considérablement réduit.The transistor 4 supplying only the coil of maintenance 3, whose current consumption is low, the heating of said transistor 4 is considerably reduced.

Toutefois, il peut arriver, par exemple du fait de la présence de particules de matières isolantes sur les faces du contact la ou encore du fait d'un blocage mécanique de certains composants du relais, que le contact de puissance la soit empêché de se fermer convenablement. Le bobinage 2 reste alors constamment alimenté par le transistor 4, puisque son extrémité qui est reliée au moteur M (point 7) reste à un potentiel voisin de celui de la masse.However, it can happen, for example due to the presence of insulating material particles on the contact faces or due to a blockage mechanics of some components of the relay, that the contact power is prevented from closing properly. The winding 2 then remains constantly supplied by the transistor 4, since its end which is connected to the motor M (point 7) remains at a potential close to that of the mass.

Le transistor 4 est alors très rapidement détruit par un échauffement excessif.The transistor 4 is then very quickly destroyed by excessive heating.

Un but de l'invention est de pallier cet inconvénient.An object of the invention is to overcome this disadvantage.

Elle propose à cet effet un dispositif pour la commande d'un contacteur de démarreur de véhicule automobile, ledit contacteur comportant un contact de puissance qui commande l'alimentation du moteur électrique du démarreur et au moins une bobine qui commande le déplacement dudit contact, une des bobines dudit contacteur étant montée entre la borne d'alimentation à la tension de la batterie et le moteur électrique, ledit dispositif comportant une unité pour la gestion de la commande du démarreur, ainsi qu'un transistor, contrôlé par ladite unité de gestion, qui commande l'alimentation de la ou des bobines du contacteur, caractérisé en ce que l'unité de gestion comporte des moyens pour commander le blocage du transistor lorsque, à l'issue d'un temps prédéterminé, après la fermeture de l'interrupteur de contact du véhicule, la tension en un point donné entre la bobine et le moteur n'est pas supérieure à un seuil prédéterminé.To this end, it offers a device for vehicle starter switch control automotive, said contactor comprising a contact power which controls the supply of the electric motor of the starter and at least one coil which controls the displacement of said contact, one of the coils of said contactor being mounted between the supply terminal at the battery voltage and electric motor said device comprising a unit for managing the starter control, as well as a transistor, controlled by said management unit, which controls the supply of the contactor coil (s), characterized in that the management unit includes means for controlling the transistor blocked when, after a period of time predetermined, after closing the switch vehicle contact, the voltage at a given point between the coil and motor is not more than a threshold predetermined.

Un tel dispositif est avantageusement complété par les différentes caractéristiques suivantes prises seules ou selon toutes leurs combinaisons possibles :

  • l'unité de gestion est un microprocesseur qui reçoit sur une entrée un convertisseur analogique/ numérique, la tension audit point entre ladite bobine et ledit moteur électrique.
  • le transistor est commandé par l'unité de gestion de façon tout ou rien ;
  • l'unité de gestion commande le transistor de façon à réaliser une alimentation progressive de la ou des bobines du contacteur.
Such a device is advantageously supplemented by the following different characteristics taken alone or in all of their possible combinations:
  • the management unit is a microprocessor which receives on an input an analog / digital converter, the voltage at said point between said coil and said electric motor.
  • the transistor is controlled by the management unit in an all or nothing manner;
  • the management unit controls the transistor so as to produce a progressive supply of the contactor coil (s).

L'invention concerne également un dispositif pour la commande de l'alimentation d'un démarreur de véhicule automobile qui comprend un contacteur comportant un contact de puissance qui commande l'alimentation du moteur électrique du démarreur et au moins une bobine qui commande le déplacement dudit contact, caractérisé en ce qu'il comporte en outre un dispositif de commande de contacteur du type précité.The invention also relates to a device for control of the power supply of a vehicle starter automobile which comprises a contactor comprising a power contact which controls the motor supply starter motor and at least one coil which controls the movement of said contact, characterized in that that it further comprises a device for controlling contactor of the aforementioned type.

Elle concerne en outre un démarreur qui intègre un tel dispositif de commande.It also relates to a starter which incorporates a such control device.

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, déjà analysée, représente schématiquement un démarreur comportant un dispositif de commande électronisé ;
  • la figure 2 est une représentation semblable à celle de la figure 1 pour un démarreur comportant un dispositif de commande conforme à un mode de réalisation possible de l'invention ;
  • la figure 3 est un organigramme qui illustre différentes étapes mises en oeuvre par le microprocesseur du dispositif de la figure 2.
Other characteristics and advantages of the invention will emerge from the description which follows. This description is purely illustrative and not limiting. It must be read in conjunction with the appended drawings in which:
  • FIG. 1, already analyzed, schematically represents a starter comprising an electronic control device;
  • Figure 2 is a representation similar to that of Figure 1 for a starter having a control device according to a possible embodiment of the invention;
  • FIG. 3 is a flowchart which illustrates different steps implemented by the microprocessor of the device of FIG. 2.

Le démarreur illustré sur la figure 2 comporte une structure analogue à celle illustrée sur la figure 1 et comporte en plus une liaison 8 entre d'une part le point 7 commun au moteur M et à la bobine 2 et d'autre part un convertisseur analogique/numérique en entrée du microprocesseur 5.The starter illustrated in Figure 2 has a structure similar to that illustrated in FIG. 1 and additionally includes a connection 8 between point 7 on the one hand common to motor M and to coil 2 and on the other hand a analog / digital converter at input of microprocessor 5.

Cette liaison 8 permet d'injecter la tension audit point 7 dans le microprocesseur 5.This link 8 makes it possible to inject the audit voltage point 7 in the microprocessor 5.

Le fonctionnement du microprocesseur 5 est le suivant.The operation of the microprocessor 5 is the following.

Lorsqu'il détecte l'apparition d'une tension sur son entrée qui est reliée à la borne B+ - c'est-à-dire lorsqu'il détecte la fermeture de l'interrupteur 6 de contact du véhicule par le conducteur - le microprocesseur 5 injecte sur la grille du transistor 4 une tension qui ferme ledit transistor 4 (étape 10 sur la figure 3). Les bobines d'appel et de maintien 2 et 3 sont alors alimentées.When it detects the appearance of a voltage on its input which is connected to terminal B + - that is to say when it detects the closing of switch 6 of contact of the vehicle by the driver - the microprocessor 5 injects a voltage on the gate of transistor 4 which closes said transistor 4 (step 10 in FIG. 3). The call and hold coils 2 and 3 are then powered.

A l'issue d'un temps T1 déterminé à partir de la fermeture de l'interrupteur de contact 6, le microprocesseur 5 détermine la valeur U de la tension au point 7 (étape 11) et compare cette valeur à une valeur seuil U0 donnée (test 12).At the end of a time T 1 determined from the closing of the contact switch 6, the microprocessor 5 determines the value U of the voltage at point 7 (step 11) and compares this value with a threshold value U 0 data (test 12).

La valeur seuil U0 est choisie de façon à être caractéristique de l'apparition d'une tension positive au point 7, apparition qui est due au passage d'un courant dans la bobine d'appel 2 et à travers le moteur M.The threshold value U 0 is chosen so as to be characteristic of the appearance of a positive voltage at point 7, appearance which is due to the passage of a current in the call coil 2 and through the motor M.

La valeur de U0 est par exemple avantageusement comprise entre 1 et 8 Volts.The value of U 0 is for example advantageously between 1 and 8 Volts.

Le temps T1 est quant à lui choisi supérieur au temps To qui s'écoule normalement entre la fermeture de l'interrupteur de contact 6 du véhicule et la fermeture du contact de puissance la. Ce temps To est habituellement compris entre 20 et 200 millisecondes.The time T 1 is chosen to be greater than the time T o which normally elapses between the closing of the contact switch 6 of the vehicle and the closing of the power contact la. This time T o is usually between 20 and 200 milliseconds.

Si la tension mesurée au temps T1 n'est pas supérieure à cette valeur U0, le microprocesseur 5 commande le blocage du transistor 4 en délivrant à la grille de celui-ci une tension nulle (étape 13).If the voltage measured at time T 1 is not greater than this value U 0 , the microprocessor 5 controls the blocking of the transistor 4 by delivering to the gate thereof a zero voltage (step 13).

Le fait que la tension au point 7 n'a pas atteint la valeur seuil U0 signifie en effet que le contact de puissance la n'est pas fermé, alors qu'il devrait l'être.The fact that the voltage at point 7 has not reached the threshold value U 0 indeed means that the power contact la is not closed, whereas it should be.

T1 ayant été convenablement choisi, une telle commande permet d'interrompre le processus de démarrage avant que l'échauffement du transistor 4 ne soit devenu trop important et ne détériore ledit transistor 4.T 1 having been suitably chosen, such a command makes it possible to interrupt the starting process before the heating of transistor 4 has become too great and deteriorates said transistor 4.

Bien entendu, si au contraire, à l'issue du temps T1, la tension au point 7 devient supérieure à U0, le microprocesseur 5 poursuit le processus de démarrage (étape 14). Of course, if on the contrary, at the end of time T 1 , the voltage at point 7 becomes greater than U 0 , the microprocessor 5 continues the starting process (step 14).

Bien entendu, l'invention s'appliquerait de la même façon dans le cas où la commande de courant que réalise le transistor serait non pas de type tout ou rien mais progressive, le relais pouvant alors ne comporter qu'une seule bobine à la place d'une bobine d'appel et d'une bobine de maintien.Of course, the invention would apply from the same way in the event that the current control that realizes the transistor would not be an all or nothing type but progressive, the relay may then not include only one coil instead of a call coil and a holding coil.

Par ailleurs, on notera que le dispositif de commande électronique de démarreur illustré sur la figure 1 présente l'avantage d'être de type "autonome", c'est-à-dire de ne nécessiter aucune autre liaison électrique que celles utilisées par les démarreurs conventionnels non électronisés, à savoir un câble de commande permettant la liaison avec l'interrupteur de contact du véhicule, un câble d'alimentation de puissance relié à une borne d'alimentation, telle que la borne positive de la batterie, et un retour à la masse par la carcasse du démarreur.Furthermore, it will be noted that the device for electronic starter control shown in figure 1 has the advantage of being of the "autonomous" type, that is to say not to require any other electrical connection than those used by conventional starters not electronic, namely a control cable allowing the connection with the vehicle's contact switch, a power supply cable connected to a terminal such as the positive terminal of the battery, and a return to ground by the carcass of the starter.
