Description

PROCEDE DE PILOTAGE D’UN GROUPE MOTOPROPULSEUR D’UN VEHICULE AUTOMOBILE DANS LE CAS D’UN PATINAGE D’UNE ROUE  STEERING METHOD OF A DRIVE GROUP OF A MOTOR VEHICLE IN THE CASE OF A WHEEL SKATING
[0001 ] L’invention a trait au pilotage d’un groupe motopropulseur d’un véhicule automobile, et plus particulièrement audit pilotage lors des phases de patinage P d’au moins une première roue du véhicule automobile couplée au groupe motopropulseur. The invention relates to the control of a powertrain of a motor vehicle, and more particularly to said control during the skating phases P of at least one first wheel of the motor vehicle coupled to the powertrain.
[0002] Le groupe motopropulseur d’un véhicule automobile fournit un couple Ce d’entraînement à la au moins une première roue du véhicule automobile. Ce couple Ce d’entraînement comprend généralement un couple Ce commandé par un conducteur du véhicule automobile et un couple de compensation inertiel. The powertrain of a motor vehicle provides a driving torque Ce to the at least one first wheel of the motor vehicle. This driving torque Ce generally comprises a torque Ce controlled by a driver of the motor vehicle and an inertial compensation torque.
[0003] Le couple de compensation inertiel est ajouté au couple Ce commandé par le conducteur pour contrer une inertie de ladite au moins une première roue et d’organes du groupe motopropulseur couplés à la au moins une première roue. The inertial compensation torque is added to the torque Ce commanded by the driver to counter an inertia of said at least one first wheel and of members of the powertrain coupled to the at least one first wheel.
[0004] Le couple de compensation inertiel évite ainsi le ressenti, par le conducteur, de ladite inertie lors de sa commande de couple Ce. The inertial compensation torque thus avoids the feeling, by the driver, of said inertia when ordering the torque Ce.
[0005] Le couple de compensation inertiel est fonction d’un gradient Gr1 d’un régime R1 de la au moins une première roue. The inertial compensation torque is a function of a gradient Gr1 of a speed R1 of the at least one first wheel.
[0006] Un procédé connu de pilotage d’un groupe motopropulseur est représenté sur la figure 2. A known method of driving a powertrain is shown in Figure 2.
[0007] La figure 2 est un graphique représentant un couple C et un régime R en fonction du temps t. Figure 2 is a graph showing a torque C and a speed R as a function of time t.
[0008] Sur la figure 2 est illustré : le couple Ce d’entraînement de la au moins une première roue du véhicule automobile par le groupe motopropulseur (en trait plein, en haut) ; le couple Ce commandé par le conducteur du véhicule automobile (en trait pointillé large) ; le régime R1 de la au moins une première roue (en trait mixte) ; le gradient Gr1 du régime R1 de la au moins une première roue (en trait pointillé fin) ; un régime R2 d’au moins une deuxième roue non couplée au groupe motopropulseur (en trait plein, en bas). In FIG. 2 is illustrated: the drive torque Ce of the at least one first wheel of the motor vehicle by the powertrain (in solid line, at the top); the torque Ce ordered by the driver of the motor vehicle (in large dotted lines); the R1 speed of the at least one first wheel (in phantom); the gradient Gr1 of the R1 regime of the at least one first wheel (in thin dotted lines); an R2 speed of at least one second wheel not coupled to the powertrain (solid line, below).
[0009] Dans le mode de réalisation représenté, le couple Ce commandé par le conducteur est constant. In the embodiment shown, the torque Ce controlled by the driver is constant.
[0010] On remarque que, lors d’un patinage P de ladite au moins une première roue, entre les instant t1 et t3, le couple de compensation inertiel, fonction du gradient Gr1 du régime R1 de la au moins une première roue et s’ajoutant au couple Ce commandé par le conducteur, augmente le couple Ce d’entraînement augmentant ainsi le régime R1 de la au moins une première roue et donc le patinage P de cette au moins une première roue. Note that, during a slip P of said at least one first wheel, between times t1 and t3, the inertial compensation torque, a function of the gradient Gr1 of the R1 regime of the at least one first wheel and s 'adding to the torque Ce controlled by the driver, increases the driving torque Ce thus increasing the speed R1 of the at least one first wheel and therefore the slip P of this at least one first wheel.
[001 1 ] L’objectif est de proposer un procédé de pilotage d’un groupe motopropulseur d’un véhicule automobile couplé à au moins une première roue du véhicule automobile, le procédé de pilotage réduisant un patinage P de ladite au moins une première roue. The objective is to propose a method for driving a powertrain of a motor vehicle coupled to at least one first wheel of the motor vehicle, the driving method reducing slippage P of said at least one first wheel. .
[0012] A cet effet, il est proposé, en premier lieu, un procédé de pilotage d’un groupe motopropulseur d’un véhicule automobile selon lequel le groupe motopropulseur fournit un couple d’entraînement à au moins une première roue du véhicule automobile en fonction d’un couple commandé par le conducteur du véhicule automobile et, lorsqu’il y a changement du couple commandé, est ajouté au couple commandé un couple de compensation inertiel ; dans le cas d’un patinage de la au moins une première roue, l’ajout du couple de compensation inertiel est désactivé. To this end, it is proposed, firstly, a method of driving a powertrain of a motor vehicle according to which the powertrain provides a drive torque to at least one first wheel of the motor vehicle. function of a torque controlled by the driver of the motor vehicle and, when there is a change in the commanded torque, an inertial compensation torque is added to the commanded torque; in the case of slipping of the at least one first wheel, the addition of the inertial compensation torque is deactivated.
[0013] Le procédé de pilotage limite ainsi le couple d’entraînement de la au moins une première roue couplée au groupe motopropulseur lorsque le patinage de la au moins une première roue est détecté. The steering method thus limits the driving torque of the at least one first wheel coupled to the powertrain when the slip of the at least one first wheel is detected.
[0014] Il est proposé, en second lieu, un véhicule automobile comprenant un groupe motopropulseur, au moins une première roue apte à être couplée au groupe motopropulseur et un moyen de mise en oeuvre d’un procédé de pilotage du groupe motopropulseur tel que précédemment décrit.

[0017] La figure 1 représente un véhicule 100 automobile comprenant un groupe 1 10 motopropulseur et au moins une première roue 120 apte à être couplée au groupe 1 10 motopropulseur. Figure 1 shows a motor vehicle 100 comprising a group 1 10 powertrain and at least one first wheel 120 adapted to be coupled to the group 1 10 powertrain.

[0029] Un procédé de pilotage du groupe 1 10 motopropulseur du véhicule 100 automobile lors d’un patinage P de la au moins une première roue 120 à laquelle est couplé le groupe 1 10 motopropulseur est représenté sur le graphique de la figure 3. A method of driving the powertrain group 1 10 of the motor vehicle 100 during a slip P of the at least one first wheel 120 to which the powertrain group 1 10 is coupled is shown in the graph in FIG. 3.
[0030] La figure 3 est un graphique représentant un couple C et un régime R en fonction du temps t. Figure 3 is a graph showing a torque C and a speed R as a function of time t.
[0031 ] Sur la figure 3 est illustré : un couple Ce d’entraînement de la au moins une première roue 120 du véhicule 100 automobile par le groupe 1 10 motopropulseur (en trait plein, en haut) ; un couple Ce commandé par un conducteur du véhicule 100 automobile (en trait pointillé large) ; un régime R1 de la au moins une première roue 120 (en trait mixte) ; un gradient Gr1 du régime R1 de la au moins une première roue 120 (en trait pointillé fin) ; un régime R2 de la au moins une deuxième roue 130 (en trait plein, en bas). [0032] Dans le mode de réalisation représenté, le couple Ce commandé par le conducteur est constant. In Figure 3 is illustrated: a torque Ce of the drive of the at least one first wheel 120 of the motor vehicle 100 by the group 1 10 powertrain (solid line, above); a torque Ce commanded by a driver of the motor vehicle 100 (in large dotted lines); a speed R1 of the at least one first wheel 120 (in phantom); a gradient Gr1 of the speed R1 of the at least one first wheel 120 (in thin dotted lines); a speed R2 of the at least one second wheel 130 (in solid lines, at the bottom). In the embodiment shown, the torque Ce controlled by the driver is constant.
[0033] Dans le mode de réalisation représenté, la deuxième motorisation 1 13 n’est pas couplée à la au moins une deuxième roue 130 laissant cette au moins une deuxième roue 130 libre en rotation. In the embodiment shown, the second motorization 1 13 is not coupled to the at least one second wheel 130 leaving this at least one second wheel 130 free to rotate.
[0034] A un instant tO, le conducteur du véhicule 100 automobile commande le couple Ce. Le procédé de pilotage comprend une première étape de commande du couple Ce d’entraînement. At an instant tO, the driver of the motor vehicle 100 controls the torque Ce. The piloting process comprises a first step of controlling the driving torque Ce.
[0035] Au cours de cette première étape, la au moins une première roue 120 n’est pas en rotation. La au moins une première roue 120 n’a donc pas d’inertie et le couple Ce d’entraînement de la au moins une première roue 120 est ainsi égal au couple Ce commandé. During this first step, the at least one first wheel 120 is not in rotation. The at least one first wheel 120 therefore has no inertia and the driving torque Ce of the at least one first wheel 120 is thus equal to the torque Ce commanded.
[0036] A un instant t1 , la au moins une première roue 120 se met en rotation. At an instant t1, the at least one first wheel 120 starts to rotate.
[0037] Le patinage P de la au moins une première roue 120 est détecté. Le procédé de pilotage comprend une deuxième étape de commande du couple Ce d’entraînement. The slippage P of the at least one first wheel 120 is detected. The piloting process comprises a second step of controlling the driving torque Ce.
[0038] Au cours de cette deuxième étape, le couple Ce d’entraînement est égal au couple Ce commandé. During this second step, the driving torque Ce is equal to the commanded torque Ce.
[0039] Le couple Ce d’entraînement n’est, lors de cette deuxième étape de commande, pas fonction de l’inertie de la au moins une première roue 120 et d’organes du groupe 1 10 motopropulseur couplés à ladite au moins une première roue 120. The torque This drive is not, during this second control step, not a function of the inertia of the at least one first wheel 120 and of organs of the drive train 1 10 coupled to said at least one first wheel 120.
[0040] A un instant t2, le régime R2 de la au moins une deuxième roue 130 devient positif. Le véhicule 100 automobile commence donc à rouler. At an instant t2, the speed R2 of the at least one second wheel 130 becomes positive. The motor vehicle 100 therefore begins to roll.
[0041 ] Néanmoins, le patinage P de la au moins une première roue 120 est toujours détecté. La deuxième étape de commande du couple Ce d’entraînement est donc toujours effective. However, the slip P of the at least one first wheel 120 is still detected. The second step of controlling the driving torque Ce is therefore still effective.
[0042] A un instant t3, le régime R1 de la au moins une première roue 120 et le régime R2 de la au moins une deuxième roue 130 deviennent égaux. [0043] Le patinage P de la au moins une première roue n’est plus détecté. Le procédé de pilotage comprend alors une troisième étape de commande du couple Ce d’entraînement. At an instant t3, the speed R1 of the at least one first wheel 120 and the speed R2 of the at least one second wheel 130 become equal. The slippage P of the at least one first wheel is no longer detected. The piloting process then comprises a third step of controlling the driving torque Ce.
[0044] Au cours de cette troisième étape, le couple Ce d’entraînement est fonction du couple Ce commandé par le conducteur et d’un couple de compensation inertiel compensant l’inertie de la au moins une première roue 120 et d’organes du groupe 1 10 motopropulseur couplés à ladite au moins une première roue 120. During this third step, the drive torque Ce is a function of the torque Ce controlled by the driver and of an inertial compensation torque compensating for the inertia of the at least one first wheel 120 and of organs of the group 1 10 power train coupled to said at least one first wheel 120.
[0045] Le couple Ce d’entraînement de cette troisième étape est donc fonction du couple Ce commandé et du gradient Gr1 du régime R1 de la au moins une première roue 120. The driving torque Ce of this third step is therefore a function of the commanded torque Ce and of the gradient Gr1 of the speed R1 of the at least one first wheel 120.
[0046] Les graphiques représentés sur les figures sont des exemples d’application du procédé de pilotage dont les courbes peuvent avoir une allure différente que celles représentées en fonction, par exemple, des commandes du conducteur ou encore de la vitesse du véhicule 100 automobile. The graphs shown in the figures are examples of application of the piloting process, the curves of which may have a different appearance than those shown as a function, for example, of the driver's commands or of the speed of the motor vehicle 100.
[0047] Le procédé de pilotage limite ainsi le couple Ce d’entraînement de la au moins une première roue 120 couplée au groupe 1 10 motopropulseur lorsque le patinage P de la au moins une première roue 120 est détecté. The steering method thus limits the driving torque Ce of the at least one first wheel 120 coupled to the drive train 1 10 when the slip P of the at least one first wheel 120 is detected.
[0048] La limitation du couple d’entraînement, dans le cas du patinage P de la au moins une première roue, permet de réduire le temps de patinage P de la au moins une première roue et permet, ainsi, de réduire la consommation du véhicule 100 automobile ainsi qu’une usure prématurée de certaines pièces du véhicule 100 automobile telles que les pneumatiques. The limitation of the drive torque, in the case of the slipping P of the at least one first wheel, makes it possible to reduce the skating time P of the at least one first wheel and thus makes it possible to reduce the consumption of the 100 motor vehicle as well as premature wear of certain parts of the motor vehicle 100 such as tires.
[0049] Le procédé de pilotage permet également, lorsqu’aucun patinage P n’est détecté, de compenser l’inertie de la au moins une première roue 120 et d’organes du groupe 1 10 motopropulseur couplés à ladite au moins une première roue 120. The steering method also makes it possible, when no slip P is detected, to compensate for the inertia of the at least one first wheel 120 and of organs of the drive train 1 10 coupled to said at least one first wheel 120.
[0050] Dans un mode de réalisation différent, lorsque la au moins une deuxième roue 130 est couplée au groupe 1 10 motopropulseur, le procédé de pilotage est mis en oeuvre pour la deuxième motorisation 1 13 de manière indépendante à une mise en oeuvre de ce procédé pour la première motorisation 1 1 1 , 1 12. In a different embodiment, when the at least one second wheel 130 is coupled to the drive train 1 10, the control process is implemented for the second engine 1 13 independently of an implementation of this process for the first motorization 1 1 1, 1 12.
