demande, afin d'éviter l'échanffement du moteur lorsque l'embrayage est débrayé pour un changement de vitesse, il est nocessaire de contrôler le couple d'embrayage de sorte qu'il suit le couple moteur. Classiquement, le couple moteur est commandé au moyen d'un système de commande de gestion du moteur ou au moyen du papillon des gaz, lorsque celui-ci est motorisé. Le temps de réponse du moteur sur une requête de couple est typiquement de l'ordre de 100 à 200 ms. Par conséquent, il existe un retard de 100 à 200 ms à partir du moment o le conducteur déclenche le changement de vitesse jusqu'à ce qu'il y ait un changement notable dans le moteur ou dans le couple d'embrayage. Ce retard est request, in order to avoid the exchanging of the engine when the clutch is disengaged for a gear change, it is necessary to check the clutch torque so that it follows the engine torque. Conventionally, the engine torque is controlled by means of an engine management control system or by means of the throttle valve, when the latter is motorized. The response time of the motor on a torque request is typically of the order of 100 to 200 ms. Therefore, there is a delay of 100 to 200 ms from the moment the driver initiates the gear change until there is a noticeable change in the engine or in the clutch torque. This delay is
perqu par le conducteur comme un changement lent. perceived by the driver as a slow change.
Lorsqu'une machine électrique telle que le démarreur/alternateur combiné est raccordée directement au moteur, il est possible de contrôler rapidement et précisément le couple moteur disponible pour la transmission par le biais de 1'embrayage en modifiant le couple appliqué par la machine électrique, par le réglage approprié du courant d'enroulement inducteur de la machine. Par conséquent, le retard dans le débrayage de 1'embrayage peut être considérablement réduit, l'échauffement du moteur étant commandé au moyen du couple appliqué par la machine électrique. En outre, la machine électrique peut être utilisée pour synchroniser la vitesse du moteur avec la vitesse de l'arbre d' entrée de la boîte de vitesses, après que l' embrayage ait été débrayé et également pour commander la remise en état du couple moteur après qu'une nouvelle vitesse When an electric machine such as the combined starter / alternator is connected directly to the engine, it is possible to quickly and precisely control the engine torque available for transmission by means of the clutch by modifying the torque applied by the electric machine, by the appropriate setting of the inductor winding current of the machine. Consequently, the delay in disengaging the clutch can be considerably reduced, the heating of the engine being controlled by means of the torque applied by the electric machine. In addition, the electric machine can be used to synchronize the speed of the engine with the speed of the input shaft of the gearbox, after the clutch has been disengaged and also to control the restoration of the engine torque. after a new gear
ait été mise en prise.has been engaged.

Comme représenté sur la figure 2a, un démarreur/alternateur combiné 100 peut être raccordé de manière entraînée au viletrequin 102 du moteur 10, entre le moteur 10 et l'embrayage 14. Le démarreur/alternateur combiné 100 peut être raccordé de manière entraînce au vilebrequin de n'importe quelle manière appropriée, par exemple, un engrenage 104 sur le démarreur/alternateur combiné 100 mettant en prise une bague d'engrenage 106 sur le volant moteur du moteur 10. En variante, une courroie ou chaîne peut être utilisée pour raccorder le démarreur/alternateur As shown in FIG. 2a, a combined starter / alternator 100 can be connected in a driven manner to the crankshaft 102 of the engine 10, between the engine 10 and the clutch 14. The combined starter / alternator 100 can be connected in a driving way to the crankshaft in any suitable manner, for example, a gear 104 on the combined starter / alternator 100 engaging a gear ring 106 on the flywheel of the engine 10. Alternatively, a belt or chain may be used to connect the starter / alternator

Dans le mode de réalisation illustré sur la figure 2b, un démarreur/alternateur 100 est raccordé de manière entraînée au vilebrequin 102 du moteur 10, mais à l'extrémité de celui-ci opposé à l'embrayage 14. Une poulie 110 sur le démarreur/alternateur combiné, est raccordée de manière entraînée à une poulie 112 sur le In the embodiment illustrated in FIG. 2b, a starter / alternator 100 is connected in a driven manner to the crankshaft 102 of the engine 10, but at the end of the latter opposite to the clutch 14. A pulley 110 on the starter / combined alternator, is connected in a driven manner to a pulley 112 on the
vilebrequin 102 par une courroie 114. crankshaft 102 by a belt 114.
Dans le mode de réalisation illustré sur la figure 2c, un rotor 202 d'un démarreur alternateur combiné 200, est monté directement sur un artre d'entraînement 204 raccordant le moteur 10 à 1'embrayage 14. Un stator 206 du démarreur/alternateur combiné 200 entoure le rotor 202 et est fixé à un boîtier non rotatif de la transmission. Comme représenté sur la figure 3, lorsque le véhicule se déplace réqulièrement avec l'embrayage mis en prise, le couple d'embrayage illustré par la ligne In the embodiment illustrated in FIG. 2c, a rotor 202 of a combined alternator starter 200 is mounted directly on a drive bar 204 connecting the engine 10 to the clutch 14. A stator 206 of the combined starter / alternator 200 surrounds the rotor 202 and is fixed to a non-rotating transmission housing. As shown in Figure 3, when the vehicle moves smoothly with the clutch engaged, the clutch torque illustrated by the line
300 dépasse le couple moteur illustré par le ligne 302. 300 exceeds the engine torque illustrated by line 302.
Suite à l'enclenchement d'un changement de vitesse à l' instant to, l'unité de commande 36 demande une réduction dans le couple moteur illustré par la ligne 304. Ceci peut être obtenu au moyen du système de commande de gestion du moteur ou de la commande directe Following the engagement of a gear change at the instant to, the control unit 36 requests a reduction in the engine torque illustrated by line 304. This can be obtained by means of the engine management control system. or direct order
du papillon des gaz 19, lorsque celle-ci est motorisée. of the throttle valve 19, when the latter is motorized.
Il existe cependant un retard de temps t de 100 à 200 ms dans le moteur 10 pour répondre à la requête concernant la réduction du couple. Si, par conséquent l' embrayage 10 est déUrayé suite à l' enclenchement du changement de vitesse, alors le couple d'embrayage chute considérablement au dessous du couple moteur, comme représenté sur la figure 3. Ceci oblige la vitesse du moteur illustrée par la ligne 306 à augmenter rapidement, ce qui se traduit par However, there is a time delay t of 100 to 200 ms in the motor 10 to respond to the request concerning the reduction of the torque. If, consequently, the clutch 10 is released following the engagement of the gear change, then the clutch torque drops considerably below the engine torque, as shown in FIG. 3. This forces the engine speed illustrated by the line 306 to increase rapidly, which results in
l'échauffement du moteur.engine overheating.
Jusqu'à présent, afin d'éviter l'échauffement du moteur, suite à l'enclenchement d'un changement de vitesse, le couple d'embrayage est réduit au couple moteur, le détrayage de l'embrayage étant alors contrôlé, de sorte que le couple d'embrayage suit le couple moteur, comme illustré sur la figure 4. Par conséquent, il existe un retard de temps at de 100 à ms à partir du moment o le conducteur enclenche le changement de vitesse, jusqu'à ce que tout changement perceptible soit ressenti, ceci étant percu par le Up to now, in order to avoid overheating of the engine, following the engagement of a gear change, the clutch torque is reduced to the engine torque, the clutch disengagement being then controlled, so that the clutch torque follows the engine torque, as illustrated in FIG. 4. Consequently, there is a time delay at of 100 to ms from the moment when the driver engages the gear change, until any perceptible change is felt, this being perceived by the
conducteur comme un changement lent. driver like a slow change.
Selon la présente invention, suite au déclenchement d'un changement de vitesse à l' instant to, l'unité de commande 36 demande une réduction du couple moteur et en même temps commence le débrayage de l'embrayage 14 d'une manière contrôlée. De plus, l'unité de commande 36 commande le couple appliqué au moteur 10 par le démarreur/alternateur combiné 100, 200, pour faire descendre le couple moteur disponible jusqu'au couple d'embrayage, comme représenté sur la figure 5. Le couple appliqué au moteur 10 par le démarreur/alternateur combiné 100, 200, comme représenté par la ligne 308, peut être contrôlé rapidement, par la variation du courant d'enroulement inducteur du démarreur/générateur 100, 200. Le retard de temps t en mise en prise de l'embrayage 14 peut par conséquent être considérablement réduit, en proposant According to the present invention, following the initiation of a speed change at the instant to, the control unit 36 requests a reduction in the engine torque and at the same time begins the disengagement of the clutch 14 in a controlled manner. In addition, the control unit 36 controls the torque applied to the engine 10 by the combined starter / alternator 100, 200, to bring the available engine torque down to the clutch torque, as shown in FIG. 5. The torque applied to the engine 10 by the combined starter / alternator 100, 200, as shown by line 308, can be quickly controlled by varying the inductive winding current of the starter / generator 100, 200. The time delay t clutch 14 can therefore be considerably reduced, by proposing
un changement plus rapide.faster change.
De préférence, le couple appliqué par le démarreur/alternateur 100, 200 peut être contrôlé par un circuit d'asservissement à boucle fermée, la différence entre la vitesse du moteur et la vitesse du disque moteur d'embrayage comme représenté par la ligne 310 étant surveillée et le courant d'enroulement Preferably, the torque applied by the starter / alternator 100, 200 can be controlled by a closed loop control circuit, the difference between the engine speed and the speed of the clutch drive disc as shown by line 310 being monitored and the winding current

La vitesse du moteur peut également être contrôlée au moyen du démarreur/alternateur contrôlé 100, 200 de la même manière que celle décrite ci-dessus, lorsque l'embrayage 14 est débrayé, afin de synchroniser la vitesse du moteur par rapport à la vitesse du disque The engine speed can also be controlled by means of the controlled starter / alternator 100, 200 in the same manner as that described above, when the clutch 14 is disengaged, in order to synchronize the engine speed with the speed of the disk

Par ailleurs, suite à la remise en prise de l'embrayage lorsque la vitesse cible a été sélectionnée, la remise en état du couple est contrôlée au moyen de Furthermore, after the clutch has been brought back into gear when the target speed has been selected, the torque restoration is controlled by means of
l'embrayage 14 afin de proposer une prise sans à-coups. the clutch 14 to provide a smooth grip.
Le couple moteur est contrôlé afin de réduire la vitesse sélectionnée à zéro, et en même temps garantir que la vitesse du moteur et la vitesse de l'arbre d'entrée de la boîte de vitesses ont la même accélération lorsque la vitesse de glissement est de zéro. Etant donné les décalages, ceci est réalisé en utilisant un système de commande à boucle ouverte. Le démarreur/alternateur combiné 100, 200 peut encore être utilisé pour compenser les erreurs du contrôle du couple moteur et pour réduire les déviations que la stratégie de commande à boucle ouverte ne peut pas The motor torque is controlled in order to reduce the selected speed to zero, and at the same time guarantee that the motor speed and the speed of the input shaft of the gearbox have the same acceleration when the sliding speed is zero. Given the offsets, this is achieved using an open loop control system. The combined starter / alternator 100, 200 can still be used to compensate for errors in the engine torque control and to reduce deviations that the open loop control strategy cannot
