Description

La présente invention est relative à un alternateur de véhicule automobile utilisé comme générateur et comme moteur électrique pour le démarrage du moteur à combustion du véhicule.The present invention relates to a motor vehicle alternator used as a generator and as an electric motor for starting the combustion engine of the vehicle.

Classiquement, un démarreur de véhicule automobile est un moteur électrique à courant continu destiné, au démarrage, à entraîner l'arbre du moteur à combustion par exemple par l'intermédiaire d'un pignon coulissant engrènant avec une couronne d'entraînement portée par ledit arbre.Conventionally, a motor vehicle starter is a direct current electric motor intended, at start-up, to drive the shaft of the combustion engine for example by means of a sliding pinion meshing with a drive ring carried by said shaft .

Comme on le sait, il est facile de faire démarrer un moteur à combustion en entraînant son démarreur par court-circuit du contacteur du véhicule.As is known, it is easy to start a combustion engine by driving its starter by short circuit of the vehicle contactor.

Pour résoudre ce problème, il est connu d'équiper les véhicules de systèmes d'immobilisation empêchant le démarrage du moteur thermique tant qu'un signal codé de déverrouillage n'est pas reçu, par exemple par un calculateur commandant l'injection dudit moteur.To solve this problem, it is known to equip vehicles with immobilization systems preventing the engine from starting until a coded unlocking signal is received, for example by a computer controlling the injection of said engine.

Néanmoins, les calculateurs d'injection sont encore peu répandus, de sorte qu'à l'heure actuelle peu de véhicules sont équipés de tels systèmes d'immobilisation.However, injection computers are still not widespread, so that at present few vehicles are equipped with such immobilization systems.

Un but de l'invention est de proposer un autre type de système d'immobilisation.An object of the invention is to propose another type of immobilization system.

On sait depuis longtemps qu'il est possible de faire fonctionner un générateur de courant - qu'il soit de type dynamo ou de type alternateur - comme un moteur électrique.We have known for a long time that it is possible to operate a current generator - whether dynamo type or alternator type - like an electric motor.

Notamment, il a déjà été proposé d'utiliser des générateurs de courant en fonctionnement moteur pour remplacer les démarreurs de moteur à combustion.In particular, it has already been proposed to use current generators in engine operation to replace the combustion engine starters.

A titre illustratif, on pourra se référer à la demande de brevet FR - 2.722.738, dans laquelle il est décrit des moteurs hybrides comportant, en complément du moteur électrique, un alternateur monté sur l'arbre du moteur thermique. Cet alternateur joue trois fonctions : il sert à freiner le moteur électrique par entraînement du moteur thermique lors des phases de décélération du véhicule ; il joue également son rôle classique d'alternateur et charge la batterie du véhicule lorsqu'il est entraîné par le moteur à combustion ; il sert enfin à entraîner le moteur à combustion pour son démarrage.By way of illustration, reference may be made to patent application FR-2,722,738, in which hybrid motors are described comprising, in addition to the electric motor, an alternator mounted on the shaft of the heat engine. This alternator has three functions: it is used to brake the electric motor by driving the heat engine during the vehicle deceleration phases; it also plays its classic alternator role and charges the vehicle battery when it is driven by the combustion engine; it is also used to drive the combustion engine for starting.

A cet effet, le pont redresseur en sortie de l'induit de l'alternateur sert également de pont de commande des phases de l'alternateur, chaque diode étant associée à un transistor formant interrupteur monté en parallèle entre sa cathode et son anode.To this end, the rectifier bridge at the output of the armature of the alternator also serves as a control bridge for the phases of the alternator, each diode being associated with a transistor forming a switch mounted in parallel between its cathode and its anode.

Les différents transistors du pont ainsi constitué sont commandés lors du fonctionnement moteur selon des séquences permettant de faire fonctionner l'alternateur en moteur électrique.The different transistors of the bridge thus formed are controlled during engine operation according to sequences making it possible to operate the alternator as an electric motor.

Lorsque l'alternateur est utilisé comme générateur, les transistors sont ouverts et le courant en sortie de l'alternateur est redressé par les diodes.When the alternator is used as a generator, the transistors are open and the current at the output of the alternator is rectified by the diodes.

L'invention propose quant à elle un alternateur de véhicule automobile utilisé d'une part comme générateur et d'autre part comme moteur électrique pour le démarrage du moteur à combustion du véhicule, comportant un rotor bobiné et un stator à plusieurs phases reliées à un pont de diodes et d'interrupteurs pour le redressement et la commande desdites phases, ainsi qu'une unité de gestion pour la commande desdits interrupteurs, caractérisé en ce que l'unité de gestion comporte des moyens pour la reconnaissance d'un signal codé transmis par des moyens d'émission à l'intérieur du véhicule, ladite unité ne commandant les phases du stator pour le démarrage du moteur à combustion que si elle reçoit desdits moyens d'émission un signal codé autorisant ce démarrage.The invention proposes, for its part, a motor vehicle alternator used on the one hand as a generator and on the other hand as an electric motor for starting the combustion engine of the vehicle, comprising a wound rotor and a multi-phase stator connected to a diode and switch bridge for rectifying and controlling said phases, as well as a management unit for controlling said switches, characterized in that the management unit comprises means for recognizing a transmitted coded signal by emission means inside the vehicle, said unit controlling the phases of the stator for starting the combustion engine only if it receives from said emission means a coded signal authorizing this starting.

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 illustrant un alternateur conforme à l'invention ;
  • les figures 2a et 2d illustrent une séquence de commande en fonctionnement moteur de l'alternateur de la figure 1.
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:
  • Figure 1 is a diagram illustrating an alternator according to the invention;
  • FIGS. 2a and 2d illustrate a sequence of control in engine operation of the alternator of FIG. 1.

Sur la figure 1, on a représenté une machine tournante triphasée, qui constitue l'alternateur proprement dit, un pont de commande et de redressement 2, ainsi qu'une unité 3 pour la commande de ce pont 2.In FIG. 1, a three-phase rotary machine is shown, which constitutes the alternator proper, a control and rectifying bridge 2, as well as a unit 3 for controlling this bridge 2.

De façon connue en soi, la machine tournante 1 formant alternateur comprend :

  • un rotor bobiné 4 constituant l'inducteur associé à deux bagues et deux balais par lesquels est amené le courant d'excitation (de l'ordre de quelques ampères) ;
  • un stator 5 portant plusieurs bobines, constituant l'induit, qui sont connectées en étoile ou triangle dans le cas le plus fréquent d'une structure triphasée et qui délivrent vers le pont redresseur 2, en fonctionnement alternateur, la puissance électrique convertie (quelques dizaines d'ampères sous une tension de l'ordre de la tension batterie).
In a manner known per se, the rotating machine 1 forming an alternator comprises:
  • a wound rotor 4 constituting the inductor associated with two rings and two brushes through which the excitation current is brought (of the order of a few amps);
  • a stator 5 carrying several coils, constituting the armature, which are connected in star or triangle in the most frequent case of a three-phase structure and which deliver to the rectifier bridge 2, in alternator operation, the converted electrical power (a few tens of amperes under a voltage of the order of the battery voltage).

Le pont 2 est relié aux différentes phases de l'induit 5 et est monté entre la masse et une borne d'alimentation de la batterie B du véhicule. Il est constitué par une pluralité de diodes 6 formant pont redresseur, ainsi que par une pluralité d'interrupteurs tels que des transistors 7 qui sont montés en parallèle sur les diodes 6 et qui commandent les différentes phases de l'alternateur.The bridge 2 is connected to the different phases of the armature 5 and is mounted between earth and a supply terminal for the vehicle battery B. It consists of a plurality of diodes 6 forming a rectifier bridge, as well as a plurality of switches such as transistors 7 which are mounted in parallel on the diodes 6 and which control the different phases of the alternator.

En mode moteur, les diodes fonctionnent en diodes de roues libres et en mode générateur, elles fonctionnent en pont redresseur.In motor mode, the diodes operate as freewheeling diodes and in generator mode, they operate as a rectifier bridge.

Les transistors 7 sont avantageusement des transistors de type MOSFET. On notera que de tels transistors intègrent par construction une diode entre leur drain et leur source. Ils permettent par conséquent de réaliser le pont 2 de redressement et de commande de phase avec uniquement des composants transistors qui jouent le rôle à la fois d'interrupteurs et de diodes de roue libre.The transistors 7 are advantageously MOSFET type transistors. It will be noted that such transistors integrate by construction a diode between their drain and their source. They therefore make it possible to produce bridge 2 for phase rectification and control with only transistor components which play the role of both switches and freewheeling diodes.

Le fonctionnement en mode moteur d'un tel alternateur s'effectue en imposant un courant continu dans l'inducteur 4 et en délivrant sur les phases du stator 5 des signaux déphasés de 120°, idéalement sinusoïdaux mais éventuellement trapézoïdaux ou carrés.The operation in motor mode of such an alternator is effected by imposing a direct current in the inductor 4 and by delivering on the phases of the stator 5 signals phase shifted by 120 °, ideally sinusoidal but possibly trapezoidal or square.

On a illustré sur les figures 2a, 2b et 2c un exemple de séquence de commande des interrupteurs que constituent les transistors 7 par des signaux carrés délivrés par l'unité de commande. Les signaux A, B, C illustrés sur ces deux figures sont des signaux de commande de ceux des transistors 7 du pont 2 qui sont reliés à la masse. Les signaux A', B', C' qui commandent les autres transistors, c'est-à-dire reliés à la batterie, sont des signaux inverses par rapport à ces signaux A, B, C et sans recouvrement avec ceux-ci.Illustrated in FIGS. 2a, 2b and 2c is an example of a sequence for controlling the switches constituted by the transistors 7 by square signals delivered by the control unit. The signals A, B, C illustrated in these two figures are control signals of those of the transistors 7 of the bridge 2 which are connected to ground. The signals A ', B', C 'which control the other transistors, that is to say connected to the battery, are inverse signals with respect to these signals A, B, C and without overlapping with them.

C'est ce qu'on a illustré sur la figure 2d sur laquelle on a représenté le signal C' qui commande le transistor relié à celui commandé par le signal C.This is what has been illustrated in FIG. 2d in which the signal C 'is shown which controls the transistor connected to that controlled by the signal C.

Avec une telle commande, le rotor 4 réalise une rotation d'un tour lorsque chacune des phases décrit un nombre de périodes égales au nombre de paires de pôles du rotor (par exemple 8).With such a command, the rotor 4 performs a rotation of one revolution when each of the phases describes a number of periods equal to the number of pairs of poles of the rotor (for example 8).

Ce fonctionnement moteur est utilisé pour entraîner au démarrage le moteur thermique du véhicule, ce qui permet, par rapport aux véhicules classiques, de supprimer le démarreur et la couronne d'entraînement du véhicule, ainsi que le câblage de puissance généralement associé au démarreur.This engine operation is used to drive the thermal engine of the vehicle when starting, which makes it possible, compared to conventional vehicles, to suppress the starter and the drive crown of the vehicle, as well as the power wiring generally. associated with the starter.

Pour réaliser un tel démarrage du moteur de combustion, les signaux de commande des transistors 7 sont avantageusement des signaux de fréquence variable, dont la fréquence est régulée de façon croissante par l'unité 3, de façon à éviter tout décrochage du rotor 4 par rapport au champ magnétique tournant créé par la stator 5.To carry out such starting of the combustion engine, the control signals of the transistors 7 are advantageously signals of variable frequency, the frequency of which is increasingly regulated by the unit 3, so as to avoid any stalling of the rotor 4 relative to to the rotating magnetic field created by stator 5.

La régulation de fréquence est par exemple définie par l'unité 3 de façon à garantir à l'alternateur un profil de vitesse permettant le démarrage du moteur thermique.The frequency regulation is for example defined by the unit 3 so as to guarantee the alternator a speed profile allowing the engine to start.

Conformément à l'invention, l'unité de commande 3 comporte des moyens pour la reconnaissance d'un signal codé autorisant le démarrage du moteur thermique. Ce signal est transmis à l'unité 3 par des moyens d'émission à l'intérieur du véhicule. L'unité 3 ne commande les transistors 7, de façon à démarrer le moteur thermique, que si elle reçoit ce signal codé. Par conséquent, l'unité de gestion 3 et les moyens d'émission qui transmettent le code de déverrouillage à ladite unité constituent un système d'immobilisation du moteur thermique.According to the invention, the control unit 3 includes means for recognizing a coded signal authorizing the starting of the heat engine. This signal is transmitted to unit 3 by transmission means inside the vehicle. The unit 3 only controls the transistors 7, so as to start the heat engine, if it receives this coded signal. Consequently, the management unit 3 and the transmission means which transmit the unlocking code to said unit constitute a system for immobilizing the heat engine.

Les moyens d'émission sont par exemple constitués par une unité d'émission reliée à un clavier de numérotation situé au niveau du tableau de bord du véhicule et sur lequel le conducteur introduit son code avant d'actionner la clé du contacteur 11 du véhicule pour commander le démarrage du moteur thermique.The transmission means are for example constituted by a transmission unit connected to a numbering keypad located at the dashboard of the vehicle and on which the driver enters his code before actuating the key of the contactor 11 of the vehicle to order the engine to start.

En variante, les moyens d'émission peuvent être constitués par une unité à laquelle le code de déverrouillage est transmis part voie hertzienne par l'intermédiaire d'une télécommande actionnée par le conducteur, par exemple au moment de l'ouverture des portes.As a variant, the transmission means may consist of a unit to which the unlocking code is transmitted by radio means by means of a remote control actuated by the driver, for example when the doors are opened.

Immédiatement après le démarrage du moteur, l'unité 3 commande les transistors 7 de façon à fonctionner en mode alternateur.Immediately after the engine has started, the unit 3 controls the transistors 7 so as to operate in alternator mode.

A cet effet, dans un mode de mise en oeuvre de l'invention, l'unité 3 commande les transistors 7 de façon qu'ils soient ouverts aux bornes de toutes les diodes.To this end, in one embodiment of the invention, the unit 3 controls the transistors 7 so that they are open across all the diodes.

Le pont 2 est alors un pont redresseur classique. Dans un autre mode de mise en oeuvre possible, les transistors 7 sont commandés de façon à court-circuiter les diodes passantes. Ils sont uniquement ouverts aux bornes des diodes non passantes.Bridge 2 is then a conventional rectifier bridge. In another possible embodiment, the transistors 7 are controlled so as to short-circuit the pass-through diodes. They are only open at the terminals of non-passing diodes.

Ainsi, il ne circule plus de courant dans les diodes passantes, de sorte que les court-circuits ainsi réalisés permettent d'y réduire les pertes.Thus, there is no longer any current flowing in the pass-through diodes, so that the short circuits thus produced make it possible to reduce losses there.

Pour synchroniser la commande des transistors 7 par rapport au passage de l'état passant à l'état non passant des diodes 6, l'unité 3 est reliée à des moyens pour détecter le passage des diodes 6 d'un état à un autre. Ces moyens sont par exemple constitués par un capteur, tel qu'une cellule à effet hall, pour mesurer la position angulaire du rotor 4 par rapport au stator 5.To synchronize the control of the transistors 7 with respect to the transition from the on state to the non-on state of the diodes 6, the unit 3 is connected to means for detecting the passage of the diodes 6 from one state to another. These means are for example constituted by a sensor, such as a hall effect cell, for measuring the angular position of the rotor 4 relative to the stator 5.

Un tel capteur peut en outre être utilisé pour déterminer la vitesse du rotor, par exemple par comptage d'impulsions dans une fenêtre temporelle donnée, pour permettre à l'unité 3 de détecter le démarrage du moteur thermique et donc de passer du fonctionnement en mode moteur au fonctionnement en mode générateur.Such a sensor can also be used to determine the speed of the rotor, for example by counting pulses in a given time window, to allow the unit 3 to detect the start of the heat engine and therefore to switch from operation to mode. engine running in generator mode.

Par ailleurs, de façon également connu en soi, on prévoit des moyens 9 de régulation de tension destinés à maintenir la tension batterie à un niveau convenable.Furthermore, in a manner also known per se, provision is made for voltage regulation means 9 intended to maintain the battery voltage at a suitable level.

Il est également prévu un interrupteur 10, par exemple également de type MOSFET, dont l'état passant ou bloqué est commandé par l'unité de gestion 3. Cet interrupteur 10 est destiné à court-circuiter le régulateur en mode moteur de sorte que l'induit 5 est alors directement excité par la tension de la batterie.A switch 10 is also provided, for example also of the MOSFET type, the on or off state of which is controlled by the management unit 3. This switch 10 is intended to short-circuit the regulator in motor mode so that the armature 5 is then directly excited by the battery voltage.
