Definitions
- the invention relates to the field of starting and restarting an internal combustion engine. It relates to a method for controlling a starter for an internal combustion engine and to a device for protecting a ring gear of the internal combustion engine and a pinion of the starter.
- Starting an internal combustion engine thus generally uses a starter, for example an electric starter comprising a direct current electric motor.
- the electric starter is connected to the battery of the motor vehicle via a control device. When activated, the starter engages the pinion of the electric motor with the ring gear of the flywheel. The electric motor then supplies a drive torque to the pinion, which then rotates the ring gear so as to start the motor.
- a starter for example an electric starter comprising a direct current electric motor.
- the electric starter When activated, the starter engages the pinion of the electric motor with the ring gear of the flywheel.
- the electric motor then supplies a drive torque to the pinion, which then rotates the ring gear so as to start the motor.
- the Stop and Start system generates frequent restarts and therefore involves the use of an oversized starter, called "reinforced".
- This oversizing implies greater inertia in rotation and therefore a longer duration of stopping in rotation than for a conventional starter.
- the starter can still be in rotation when it is activated again when a previous activation has been aborted before the internal combustion engine has started, or when the internal combustion engine has failed to start in a time allotted during a first attempt to start or restart.
- the duration of stopping in rotation of an internal combustion engine used with a Stop and Start system, being optimized is generally shorter than that of an engine without such a system. In the end, the starter rotation time may be longer than that of the internal combustion engine. The known means of protection are then ineffective.
- the speed of rotation of the starter is considered to be substantially equal to the speed of rotation of the ring gear divided by the transmission ratio between the ring gear and the starter motor .
- the invention has the particular advantage that it protects the starter pinion and the ring gear of the internal combustion engine without requiring the addition of a sensor at the starter level.
- the invention also makes it possible to optimize the period during which activation of the starter is prevented.
- the predetermined threshold speed is for example either substantially equal to the idle speed of the starter multiplied by the transmission ratio between the ring gear and the starter, or substantially equal to a predetermined speed of rotation beyond which the engine internal combustion is considered autonomous.
- the speed of rotation of the starter can be considered to be equal to the speed of rotation of the starter when empty, increased by a value depending on the speed of rotation of the starter. toothed crown.
- the increase value can be limited to 2000 revolutions per minute.
- the model giving an estimate of the duration of stopping the starter as a function of its speed of rotation takes into account the aging of the starter by means of the number of starts it has made, the more the greater the number of starts, the longer the estimated stop time.
- FIG. 1 represents such a starter 100. It essentially comprises a solenoid 110, comprising a plunger core 111, a call winding 112 and a holding winding 113, a launcher 120 comprising a pinion 121 and a free wheel 122, a fork 130 capable of transmitting a translational movement from the plunger core 111 to the launcher 120, an electric motor 140 capable of supplying a drive torque to the pinion 121, a control circuit 150 capable of connecting the windings 112 and 113 of the solenoid 110 to a supply battery 160 such as the battery of the motor vehicle, and a power circuit 170 capable of connecting the electric motor 140 to the supply battery 160.
- a solenoid 110 comprising a plunger core 111, a call winding 112 and a holding winding 113
- a launcher 120 comprising a pinion 121 and a free wheel 122
- a fork 130 capable of transmitting a translational movement from the plunger core 111 to the launcher
- an electric current only flows in the only holding winding 113, which makes it possible to maintain the plunger core 111 and therefore the engagement between the pinion 121 and the ring gear 201.
- the power circuit 170 supplies the electric motor 140, which drives the ring gear 201 in rotation via the pinion 121.
- the motor internal combustion becomes autonomous, in other words when it becomes capable of turning without the aid of the starter 100, its speed of rotation becomes greater than that of the starter.
- Freewheel 122 of starter 100 then enters into operation and the electric motor 140 of the starter 100 operates at no load, that is to say without exerting torque.
- the figure 2 represents, in the form of a graph, an example of evolution as a function of time of a speed of rotation of the starter 100 and that of the internal combustion engine during a start.
- the abscissa axis indicates the time t in milliseconds (ms); the ordinate axis indicates the rotational speeds N in number of revolutions per minute (rpm) in the reference frame of the internal combustion engine.
- the initial instant t 0 corresponds to the instant when the electric motor 140 starts to rotate, that is to say at the instant when the power circuit 170 is closed.
- a first curve 11 represents the evolution of the speed of rotation N word of the internal combustion engine, in particular the speed of rotation of the ring gear 201.
- a second curve 12 represents the evolution of the rotation speed N dem of the starter 100 operating at no load.
- This speed N dem corresponds for example to the speed of rotation of the armature of the electric motor 140 of the starter 100 or to the speed of rotation of the pinion 121. It is represented on the graph of the figure 2 in the engine repository. In other words, it multiplied by the transmission ratio between the gear ring 201 and the armature of the electric motor 140 or between the gear ring 201 and the starter pinion 121. This transmission ratio is defined as the ratio, in the engaged position.
- the transmission ratio makes it possible to compare the tangential speeds of the toothed ring 201 and the armature of the electric motor 140 or the pinion 121, and to determine whether the freewheel 122 is in operation or not, in other words if the pinion 121 drives the toothed crown 201 or not.
- the rotation speed N dem of the starter 100 is considered in the frame of reference of the internal combustion engine.
- the internal combustion engine becomes autonomous at an instant t 1 , comprised in a time range substantially comprised between 150 and 300 ms, that is to say for a rotation speed N word substantially comprised between 300 and 400 rpm.
- the rotation speed N word of the internal combustion engine substantially follows the rotation speed N dem of the starter 100, except for the transmission ratio.
- the speed of rotation N word of the engine may for example be momentarily greater than that of the starter 100 during an explosion phase. Beyond the instant t 1 , the speed of rotation N word of the engine becomes generally greater than the speed of rotation N dem of the starter 100.
- the freewheel 122 enters into operation and the speed of rotation N dem of the starter 100 increases by tending towards the no-load speed of rotation of the starter 100.
- a torque is transmitted from the internal combustion engine to the starter 100 due to friction in the freewheel 122.
- the starter 100 therefore rotates significantly faster than no-load operation.
- the starter 100 can be deactivated. In this case, the control circuit 170 can be opened. The current then no longer flows in the holding winding 113.
- a return spring returns the plunger core 111 to its rest position. This results in a disengagement between the pinion 121 and the ring gear 201 and an opening of the power circuit 170 cutting the supply of the electric motor 140 of the starter 100.
- the electric motor 140 and the pinion 121 continue to rotate for a certain time, of the order of one or two seconds.
- the speed of rotation N dem of the pinion 121 risks being different from the speed of rotation N word of the ring gear 201.
- the invention makes it possible to prevent a new activation of the starter 100 while it is still rotating.
- the starter according to the invention comprises a device for protecting the ring gear 201 and the pinion 121.
- the protection device comprises in particular means for preventing the closing of the control circuit 170 when the pinion 121 is considered to be still in rotation.
- a starter generally does not include a speed sensor making it possible to determine its speed of rotation and whether it is rotating. Consequently, according to the invention, a stopping time necessary for stopping the starter 100 is estimated as a function, on the one hand, of the rotation speed N dem of the starter 100 estimated at the end of the start considered and, on the other hand, a model giving an estimate of the duration of stopping the starter 100 as a function of its speed of rotation at the end of a start-up. The closing of the control circuit 150 is then prevented during this entire period.
- the rotational speed N dem of the starter 100 is estimated from the rotational speed N word of the ring gear 201.
- the rotational speed N dem of the starter 100 can be estimated from any related rotational speed to that of the ring gear 201 and making it possible to determine this speed of rotation.
- the speed of rotation N word of the gear ring 201 is not always equal to the speed of rotation N dem of the starter 100. In fact, when the speed of rotation N word of the gear ring 201 becomes greater than the rotation speed N dem of the pinion 121, apart from the transmission ratio, the freewheel 122 enters into operation.
- the rotation speed N dem of the starter 100 can be estimated more precisely by considering that it follows the behavior of the transfer function of a high-pass filter of the first order whose gain corresponds to the no-load rotation speed of the starter 100 and the cutoff frequency at the threshold speed N s .
- the speed of rotation N word of the ring gear 201 is less than the threshold speed N s
- the speed of rotation N dem of the starter 100 in the reference frame of the internal combustion engine is considered to be substantially equal to the speed of rotation N word of the ring gear 201.
- the threshold speed N s is substantially equal to the no-load speed of rotation of the starter 100 in the reference frame of the internal combustion engine.
- the threshold speed N s is substantially equal to the speed of rotation beyond which the internal combustion engine is considered to be autonomous.
- the idle speed of starter 100 can be increased by a value depending on the speed of rotation of the ring gear 201.
- the increase value is for example limited to 2000 rpm.
- the model giving an estimate of the duration of stopping the starter 100 as a function of its speed of rotation at the end of a start can be indicated by the supplier of the starter 100. It can also be determined experimentally.
- the model is for example in the form of a function taking as input variable the rotation speed N dem of the starter 100 at the end of a start and giving at output a stop time.
- the brushes ensuring the current supply of the armature of the electric motor 140 wear out with the rotation of the armature and brake it less less.
- the model can thus include one or more functions, each function being representative of a state of wear of the starter 100.
- the state of wear of the starter 100 can be determined as a function of the number of starts made. by starter 100.
- the model giving an estimate of the duration of stopping the starter 100 can also be in the form of one or more functions directly taking as input variable the speed of rotation N word of the ring gear 201 at the end of 'a start.
- the figure 3 represents, in the form of a graph, an example of such a model comprising two functions.
- the abscissa axis indicates the speed of rotation N word of the ring gear 201 in revolutions per minute; the ordinate axis indicates the estimated downtime d in seconds (s).
- a first curve 21 represents the estimate of the stop time d of a starter 100 when it is considered to be new.
- a second curve 22 represents the estimate of the stop time d of the starter 100 when it is considered to be aged.
- Each curve 21, 22 comprises a first linear part 21a, 22a, representative of the fact that the speed of rotation N dem of the starter 100 is considered to be equal to the speed of rotation N word of the ring gear 201.
- the linear part 21a, 22a is thus between the zero speed and the threshold speed N s beyond which it is considered that the free wheel 122 is in operation.
- Each curve 21, 22 also includes a non-linear part 21b, 22b, representative of the fact that the starter 100 rotates substantially faster than in no-load operation due to the presence of friction in the freewheel 122.
- a contactor In order to control the open or closed state of the control circuit 150, a contactor, noted 151 on the figure 1 , is generally inserted in the control circuit 150.
- This contactor 151 can be controlled in an open or closed state by a control device.
- the signal sent by the control device to the contactor 151 to bring it into its closed state is called start command. It is considered that in the absence of a start command, the contactor 151 is in its open state.
- the control device receives, for example, information from an ignition switch which can be actuated by an ignition key. It can also receive other information such as depressing a brake pedal or an accelerator pedal, so that it can manage the automatic stopping and restarting of an internal combustion engine.
- the starter 100 comprises a protection device making it possible to prevent the engagement of its pinion 121 with the ring gear 201 of the internal combustion engine when the pinion 121 is still in rotation.
- the protection device may include means for preventing the control device from controlling the contactor 151 in its closed state during the estimated stop time d of the starter 100. These means may in particular consist of means for inhibiting any command starting during this estimated downtime d.

Description
La présente invention revendique la priorité de la demande française
L'invention se situe dans le domaine du démarrage et du redémarrage d'un moteur à combustion interne. Elle concerne un procédé de commande d'un démarreur pour un moteur à combustion interne et un dispositif de protection d'une couronne dentée du moteur à combustion interne et d'un pignon du démarreur.The invention relates to the field of starting and restarting an internal combustion engine. It relates to a method for controlling a starter for an internal combustion engine and to a device for protecting a ring gear of the internal combustion engine and a pinion of the starter.
Les moteurs à combustion interne des véhicules automobiles ne peuvent démarrer de manière autonome. Le démarrage d'un moteur à combustion interne fait ainsi généralement appel à un démarreur, par exemple un démarreur électrique comprenant un moteur électrique à courant continu. Le démarreur électrique est relié à la batterie du véhicule automobile par l'intermédiaire d'un dispositif de commande. Lorsqu'il est activé, le démarreur vient engager le pignon du moteur électrique avec la couronne dentée du volant moteur. Le moteur électrique fournit ensuite un couple d'entraînement au pignon, lequel entraîne alors en rotation la couronne dentée de manière à démarrer le moteur. Dans le but d'éviter une usure prématurée de l'engrenage constitué du pignon du démarreur et de la couronne dentée du moteur à combustion interne, il est connu de prévoir des moyens de protection pour empêcher l'activation du démarreur lorsque le moteur à combustion interne est encore en rotation, notamment lorsque le moteur à combustion interne est déjà en fonctionnement ou en cours d'arrêt.
Le but de l'invention est notamment de fournir une solution pour empêcher un engagement entre le pignon d'un démarreur et la couronne dentée d'un moteur à combustion interne alors que le pignon est encore en rotation du fait de son inertie. A cet effet, l'invention a pour objet un procédé de commande d'un démarreur apte à démarrer un moteur à combustion interne, le démarreur comprenant des moyens pour engager un pignon avec une couronne dentée du moteur à combustion interne et pour entraîner le pignon en rotation en réponse à une commande de démarrage, le procédé étant caractérisé en ce que toute commande de démarrage est inhibée pendant une durée déterminée à compter de la fin de la commande de démarrage précédente, la durée étant déterminée à partir d'une vitesse de rotation du démarreur estimée à la fin de la commande de démarrage précédente, selon un modèle donnant une estimation d'une durée d'arrêt du démarreur en fonction de sa vitesse de rotation à la fin d'une commande de démarrage. La vitesse de rotation du démarreur à la fin de la commande de démarrage précédente est estimée comme suit :
- si la vitesse de rotation de la couronne dentée est supérieure à une vitesse seuil prédéterminée, la vitesse de rotation du démarreur est considérée comme étant sensiblement égale à une vitesse de rotation à vide du démarreur,
- if the speed of rotation of the ring gear is greater than a predetermined threshold speed, the speed of rotation of the starter is considered to be substantially equal to a speed of rotation of the starter when idle,
si la vitesse de rotation de la couronne dentée est inférieure à la vitesse seuil, la vitesse de rotation du démarreur est considérée comme étant sensiblement égale à la vitesse de rotation de la couronne dentée divisée par le rapport de transmission entre la couronne dentée et le démarreur.if the speed of rotation of the ring gear is less than the threshold speed, the speed of rotation of the starter is considered to be substantially equal to the speed of rotation of the ring gear divided by the transmission ratio between the ring gear and the starter motor .
L'invention présente notamment l'avantage qu'elle permet de protéger le pignon du démarreur et la couronne dentée du moteur à combustion interne sans nécessiter l'ajout de capteur au niveau du démarreur. L'invention permet en outre d'optimiser la durée pendant laquelle l'activation du démarreur est empêchée.The invention has the particular advantage that it protects the starter pinion and the ring gear of the internal combustion engine without requiring the addition of a sensor at the starter level. The invention also makes it possible to optimize the period during which activation of the starter is prevented.
La vitesse seuil prédéterminée est par exemple soit sensiblement égale à la vitesse de rotation à vide du démarreur multipliée par le rapport de transmission entre la couronne dentée et le démarreur, soit sensiblement égale à une vitesse de rotation prédéterminée au-delà de laquelle le moteur à combustion interne est considéré autonome.The predetermined threshold speed is for example either substantially equal to the idle speed of the starter multiplied by the transmission ratio between the ring gear and the starter, or substantially equal to a predetermined speed of rotation beyond which the engine internal combustion is considered autonomous.
Si la vitesse de rotation de la couronne dentée est supérieure à la vitesse seuil, la vitesse de rotation du démarreur peut être considérée comme étant égale à la vitesse de rotation à vide du démarreur majorée d'une valeur fonction de la vitesse de rotation de la couronne dentée. La valeur de majoration peut être limitée à 2000 tours par minute.If the speed of rotation of the ring gear is greater than the threshold speed, the speed of rotation of the starter can be considered to be equal to the speed of rotation of the starter when empty, increased by a value depending on the speed of rotation of the starter. toothed crown. The increase value can be limited to 2000 revolutions per minute.
Selon une forme particulière de réalisation, le modèle donnant une estimation de la durée d'arrêt du démarreur en fonction de sa vitesse de rotation prend en compte le vieillissement du démarreur par l'intermédiaire du nombre de démarrages qu'il a effectués, plus le nombre de démarrages étant important, plus la durée d'arrêt estimée étant longue.According to a particular embodiment, the model giving an estimate of the duration of stopping the starter as a function of its speed of rotation takes into account the aging of the starter by means of the number of starts it has made, the more the greater the number of starts, the longer the estimated stop time.

Le démarreur selon l'invention comprend un dispositif de protection de la couronne dentée 201 et du pignon 121. Le dispositif de protection comprend notamment des moyens pour empêcher la fermeture du circuit de commande 170 lorsque le pignon 121 est considéré comme étant encore en rotation. Un démarreur ne comprend généralement pas de capteur de vitesse permettant de déterminer sa vitesse de rotation et le fait qu'il est ou non en rotation. Par conséquent, selon l'invention, on estime une durée d'arrêt nécessaire à l'arrêt du démarreur 100 en fonction, d'une part, de la vitesse de rotation Ndém du démarreur 100 estimée à la fin du démarrage considéré et, d'autre part, d'un modèle donnant une estimation d'une durée d'arrêt du démarreur 100 en fonction de sa vitesse de rotation à la fin d'un démarrage. La fermeture du circuit de commande 150 est alors empêchée pendant toute cette durée. La vitesse de rotation Ndém du démarreur 100 est estimée à partir de la vitesse de rotation Nmot de la couronne dentée 201. De manière alternative, la vitesse de rotation Ndém du démarreur 100 peut être estimée à partir de toute vitesse de rotation liée à celle de la couronne dentée 201 et permettant de déterminer cette vitesse de rotation. Comme indiqué précédemment, la vitesse de rotation Nmot de la couronne dentée 201 n'est pas toujours égale à la vitesse de rotation Ndém du démarreur 100. En effet, lorsque la vitesse de rotation Nmot de la couronne dentée 201 devient supérieure à la vitesse de rotation Ndém du pignon 121, au rapport de transmission près, la roue libre 122 entre en fonctionnement. Par conséquent, pour estimer la vitesse de rotation Ndém du démarreur 100 à la fin d'un démarrage, on considère deux cas distincts, dépendants de la vitesse de rotation Nmot de la couronne dentée 201 par rapport à une vitesse seuil Ns. Cette vitesse seuil Ns correspond sensiblement à la vitesse à laquelle la roue libre 122 entre en fonctionnement. Dans le cas où la vitesse de rotation Nmot de la couronne dentée 201 est supérieure à la vitesse seuil Ns, la vitesse de rotation Ndém du démarreur 100 est considérée comme étant sensiblement égale à une vitesse de rotation à vide du démarreur 100. La vitesse de rotation Ndém du démarreur 100 peut être estimée plus précisément en considérant qu'elle suit le comportement de la fonction de transfert d'un filtre passe-haut du premier ordre dont le gain correspond à la vitesse de rotation à vide du démarreur 100 et la fréquence de coupure à la vitesse seuil Ns. Dans le cas où la vitesse de rotation Nmot de la couronne dentée 201 est inférieure à la vitesse seuil Ns, la vitesse de rotation Ndém du démarreur 100 dans le référentiel du moteur à combustion interne est considérée comme étant sensiblement égale à la vitesse de rotation Nmot de la couronne dentée 201. Selon une première variante de réalisation, on considère que la vitesse seuil Ns est sensiblement égale à la vitesse de rotation à vide du démarreur 100 dans le référentiel du moteur à combustion interne. Selon une deuxième variante de réalisation, on considère que la vitesse seuil Ns est sensiblement égale à la vitesse de rotation au-delà de laquelle le moteur à combustion interne est considéré comme étant autonome.The starter according to the invention comprises a device for protecting the
Dans le cas où la vitesse de rotation Nmot de la couronne dentée 201 est supérieure à la vitesse seuil Ns, il est possible de prendre en compte le fait que le démarreur 100 tourne sensiblement plus vite qu'en fonctionnement à vide en raison de la présence de frottements dans la roue libre 122. En particulier, la vitesse de rotation à vide du démarreur 100 peut être majorée d'une valeur fonction de la vitesse de rotation de la couronne dentée 201. Plus la vitesse de rotation Nmot de la couronne dentée 201 est grande et plus la valeur de majoration sera grande. La valeur de majoration est par exemple limitée à 2000 tr/min.In the case where the speed of rotation N word of the
Le modèle donnant une estimation de la durée d'arrêt du démarreur 100 en fonction de sa vitesse de rotation à la fin d'un démarrage peut être indiqué par le fournisseur du démarreur 100. Il peut également être déterminé expérimentalement. Le modèle se présente par exemple sous la forme d'une fonction prenant comme variable d'entrée la vitesse de rotation Ndém du démarreur 100 à la fin d'un démarrage et donnant en sortie une durée d'arrêt. Par ailleurs, il est possible de prendre en compte le vieillissement du démarreur 100. En effet, les balais assurant l'alimentation en courant de l'induit du moteur électrique 140 s'usent avec la rotation de l'induit et le freinent de moins en moins. Ainsi, plus le démarreur 100 a été sollicité, plus sa durée d'arrêt est longue. Le modèle peut ainsi comporter une ou plusieurs fonctions, chaque fonction étant représentative d'un état d'usure du démarreur 100. A titre d'exemple, l'état d'usure du démarreur 100 peut être déterminé en fonction du nombre de démarrages effectués par le démarreur 100.The model giving an estimate of the duration of stopping the
Le modèle donnant une estimation de la durée d'arrêt du démarreur 100 peut également se présenter sous la forme d'une ou de plusieurs fonctions prenant directement comme variable d'entrée la vitesse de rotation Nmot de la couronne dentée 201 à la fin d'un démarrage. La
Dans le but de contrôler l'état ouvert ou fermé du circuit de commande 150, un contacteur, noté 151 sur la
manière à pouvoir gérer l'arrêt et le redémarrage automatique d'un moteur à combustion interne. Selon l'invention, le démarreur 100 comporte un dispositif de protection permettant d'empêcher l'engagement de son pignon 121 avec la couronne dentée 201 du moteur à combustion interne lorsque le pignon 121 est encore en rotation. En particulier, le dispositif de protection peut comporter des moyens pour empêcher le dispositif de commande de commander le contacteur 151 dans son état fermé pendant la durée d'arrêt estimée d du démarreur 100. Ces moyens peuvent notamment consister en des moyens pour inhiber toute commande de démarrage pendant cette durée d'arrêt estimée d. Ils comportent par exemple un interrupteur empêchant soit la fermeture du circuit de commande 150, soit l'envoi d'une commande de démarrage au contacteur 151. Le dispositif de commande et le dispositif de protection peuvent notamment être réalisés dans une fonction qui peut être intégrée dans une carte électronique ou un calculateur.In order to control the open or closed state of the
