Abstract
Description
La présente invention concerne un dispositif permettant de gérer automatiquement la stabilité des véhicules inclinables, c'est & dire d'en maitriser l'inclinaison. The present invention relates to a device for automatically managing the stability of tilting vehicles, that is to say controlling the inclination.
La stabilité de tels engins en mouvement est traditionnellement maitrisée par le pilote, par action sur le guidon et mouvement de son corps, notamment lorsqu'il s'agit de négocier un virage. The stability of such moving machines is traditionally controlled by the pilot, by action on the handlebars and movement of his body, especially when it comes to negotiating a turn.
De plus à très faible vitesse ou & l'arrêt, la stabilité dynamique de l'ensemble véhicule-pilote tend & s'annuler et c'est le pilote qui doit maintenir ltéquilibre de l'engin en posant ses pieds sur le sol de part et d'autre du véhicule de façon à agir sur le centre de gravité, et ainsi contrecarrer les petits déplacements latéraux autour de la position d'équilibre. In addition, at very low speed or at standstill, the dynamic stability of the pilot-vehicle assembly tends to cancel out and it is the pilot who must maintain the balance of the machine by placing his feet on the ground. and other of the vehicle so as to act on the center of gravity, and thus counteract small lateral displacements around the equilibrium position.
Le dispositif selon l'invention permet de remedier à ces deux inconvénients, à savoir
- l'action trés physique du pilote qui doit agir avec tout son corps pour maitriser la stabilité dynamique du véhicule.The device according to the invention overcomes these two drawbacks, namely
- the very physical action of the driver who must act with his whole body to control the dynamic stability of the vehicle.
- l'instabilité dans les phases à très basse vitesse ou à l'arrêt oû là encore le pilote est sollicité, pour agir avec ses pieds, pour assurer une stabilité statique à l'engin. - the instability in the phases at very low speed or at the stop where again the pilot is requested, to act with his feet, to ensure a static stability to the machine.
Le dispositif comporte selon une première caractéristique un pendule, libre selon l'axe latéral de l'engin, qui permet de mesurer l'inclinaison du véhicule par rapport à l'axe vertical du pendule (angle a). According to a first characteristic, the device comprises a pendulum, free along the lateral axis of the machine, which makes it possible to measure the inclination of the vehicle relative to the vertical axis of the pendulum (angle a).
En effet, au gré des déplacements de l'ensemble véhicule-pilote, la verticale dynamique de cet ensemble, résultante de l'action de la force centrifuge, tend à se dissocier de la verticale réelle. L'axe vertical du pendule représentera en permanence la verticale dynamique de l'ensemble en mouvement. Indeed, as the vehicle-pilot assembly moves, the dynamic vertical of this assembly, resulting from the action of centrifugal force, tends to dissociate from the real vertical. The vertical axis of the pendulum will permanently represent the dynamic vertical of the moving assembly.
Ce pendule est associé à un système électronique de mesure et de gestion de l'angle a , dont le but est d'annuler en permanence cet angle a en agissant, selon une deuxième caractéristique, sur deux bras articulables, terminés par de petites roues, situés de part et d'autre du véhicule, qui en inclinant l'engin par action sur le sol rameneront en permanence l'angle a à la valeur nulle. This pendulum is associated with an electronic system for measuring and managing the angle a, the aim of which is to permanently cancel this angle a by acting, according to a second characteristic, on two articulated arms, terminated by small wheels, located on either side of the vehicle, which by tilting the vehicle by action on the ground will permanently reduce the angle a to zero.
Ainsi selon la présente invention, la conduite des véhicules à stabilité dynamique se trouve complètement révolutionnée, notamment en courbe. Thus according to the present invention, the driving of vehicles with dynamic stability is completely revolutionized, especially in curves.
A l'abord d'un virage le pilote n'a plus à déplacer son corps pour agir sur le centre de gravité de l'engin, il lui suffit de tourner l'organe de direction. Le pendule se trouve amené, sous l'effet de la force centrifuge, à amorcer un angle a par rapport à la verticale du véhicule. Le système électronique de mesure-gestion de l'angle a agit sur le mécanisme des bras de stabilisation de façon à ramener cet angle à la valeur nulle et ainsi à incliner l'engin d'un angle a. When entering a turn, the pilot no longer has to move his body to act on the center of gravity of the craft, he just has to turn the steering member. The pendulum is caused, under the effect of centrifugal force, to initiate an angle a with respect to the vertical of the vehicle. The electronic system for measuring and managing the angle a acts on the mechanism of the stabilization arms so as to bring this angle to zero and thus to tilt the machine by an angle a.
Cette opération de mesure de l'angle a et l'ordre transmis aux bras d'incliner d'autant le véhicule, est réalisée plusieurs centaines de fois par seconde de façon à ce que l'engin "colle" à sa verticale dynamique dans un mouvement d'inclinaison continu. This operation of measuring the angle a and the order transmitted to the arms to tilt the vehicle by as much, is carried out several hundred times per second so that the machine "sticks" to its dynamic vertical in a continuous tilting motion.
La somme algébrique des angles o' représente à un instant donné l'inclinaison du véhicule par rapport à la verticale réelle et constitue en permanence l'angle que doit avoir l'engin pour négocier au mieux la courbe dans laquelle il se trouve. The algebraic sum of the angles o 'represents at a given instant the inclination of the vehicle with respect to the real vertical and permanently constitutes the angle which the machine must have to best negotiate the curve in which it is located.
En ligne droite ou à l'arrêt l'analyse permanente de l'angle a et l'action résultante exercée par les bras sur le sol permet de contrecarrer toute stabilité défaillante de l'ensemble vehicule-pilote. In a straight line or at a standstill, the permanent analysis of the angle a and the resulting action exerted by the arms on the ground makes it possible to counteract any defective stability of the pilot vehicle assembly.
Les figures 1 à 7 sont des vues par l'arrière représentant le dispositif selon l'invention à différents moments caractéristiques d'une évolution de l'engin. Figures 1 to 7 are views from the rear showing the device according to the invention at different times characteristic of an evolution of the machine.
La figure 8 est une vue de côté mettant en évidence les possibilités d'uscillation des bras de stabilisation. Figure 8 is a side view showing the possibilities of oscillation of the stabilization arms.
La figure 9 est une vue par l'arrière représentant une autre forme d'exécution des bras de stabilisation. Figure 9 is a rear view showing another embodiment of the stabilization arms.
En référence à ces dessins la figure 1 représente le dispositif selon l'invention pour le véhicule (1), vu par l'arrière, en ligne droite. L'axe vertical (2) de l'ensemble véhicule-pilote se confond avec l'axe vertical (3) du pendule (4), la roue arrière (5) (et la roue avant) de l'engin (1) est perpendiculaire au sol (6). Les longueurs L1 (12) et L2 (13) es à l'ouverture verticale des bras de stabilisation (8-9), terminés par de petites roues (lO-11), sont égales. With reference to these drawings, FIG. 1 represents the device according to the invention for the vehicle (1), seen from the rear, in a straight line. The vertical axis (2) of the pilot vehicle assembly merges with the vertical axis (3) of the pendulum (4), the rear wheel (5) (and the front wheel) of the machine (1) is perpendicular to the ground (6). The lengths L1 (12) and L2 (13) are at the vertical opening of the stabilization arms (8-9), terminated by small wheels (lO-11), are equal.
La figure 2 représente le dispositif selon l'invention à l'instant ti quand le véhicule (1) amorçe une courbe. Le pilote vient d'agir sur l'organe de direction. Sous l'effet de la force centrifuge le pendule (4) est déporté vers l'extérieur de la courbe. il se cré alors entre l'axe vertical (3) du pendule (4) et l'axe vertical (2) du véhicule (1) un angle ai (7a) non nul. A cet instant l'ordre d'agir sur le mécanisme des bras de stabilisation (8-9) n'a pas encore bté transmis. L1 (12) est toujours égal à L2 (13). Figure 2 shows the device according to the invention at time ti when the vehicle (1) starts a curve. The pilot has just acted on the management body. Under the effect of centrifugal force the pendulum (4) is offset towards the outside of the curve. there is then created between the vertical axis (3) of the pendulum (4) and the vertical axis (2) of the vehicle (1) a non-zero angle ai (7a). At this instant the order to act on the mechanism of the stabilization arms (8-9) has not yet been transmitted. L1 (12) is always equal to L2 (13).
La figure 3 représente ce qui se passe à l'instant t2, éloigné de quelques centièmes de seconde de l'instant tl. Figure 3 shows what happens at time t2, a few hundredths of a second away from time tl.
Le système de gestion électronique de l'angle a a reçu l'information selon laquelle un angle ai (7a) non nul vient de se crier. il a transmis au mécanisme des bras de stabilisation (8-9) l'ordre de modifier les longueurs L1 (12) et L2 (13), c'est à dire d'incliner l'engin (1) afin de ramener l'angle ai (7a) à la valeur nulle.The electronic angle management system a has received information that a non-zero angle ai (7a) has just screamed. he transmitted to the mechanism of the stabilization arms (8-9) the order to modify the lengths L1 (12) and L2 (13), that is to say to tilt the machine (1) in order to bring the angle ai (7a) at zero.
Pendant ce temps le pendule (4) a continué de se déporter par rapport à la nouvelle verticale (2) de l'engin (1), d'un angle additionnel a2 (7b).During this time the pendulum (4) continued to move away from the new vertical (2) of the machine (1), by an additional angle a2 (7b).
La figure 4 représente ce qui se passe à l'instant t3. Figure 4 shows what is happening at time t3.
Selon le même principe qu'à l'instant t2 immédiatement précédent le système de gestion électronique de l'angle a a resu l'information selon laquelle un angle a2 (7b) non nul vient d'apparaitre. Il a à nouveau transmis au mécanisme des bras de stabilisation (8-9) l'ordre de modifier les longueurs Ll (12) et L2 (13), c'est à dire d'incliner encore l'engin (1) afin de ramener l'angle a2 (7b) à la valeur nulle.According to the same principle as at instant t2 immediately preceding the electronic angle management system has received the information according to which a non-zero angle a2 (7b) has just appeared. He again transmitted to the mechanism of the stabilization arms (8-9) the order to modify the lengths L1 (12) and L2 (13), that is to say to tilt the machine (1) further in order to reduce the angle a2 (7b) to zero.
A ce moment le véhicule (1) est complbtement rentré dans la courbe, un angle ax additionnel ne se cré plus. L'axe vertical (2) de l'engin (l) et celui (3) du pendule (4) se confondent. Le véhicule (1) est incliné d'un angle a égal à ai (7a) + 2 (7h). At this time the vehicle (1) is completely returned to the curve, an additional axial angle is no longer created. The vertical axis (2) of the machine (l) and that (3) of the pendulum (4) merge. The vehicle (1) is inclined at an angle a equal to ai (7a) + 2 (7h).
La figure 5 représente ce qui se passe à l'instant t4. Figure 5 shows what is happening at time t4.
Le véhicule (l) commence à ammorcer sa sortie du virage. Le pendule (4) est alors ramené vers l'intérieur de la courbe.The vehicle (l) begins to initiate its exit from the turn. The pendulum (4) is then brought back towards the inside of the curve.
il se cré donc entre l'axe vertical (3) du pendule (4) et l'axe vertical (2) du véhicule (l) un angle 3 (7c) non nul. A cet instant l'ordre d'agir sur le mécanisme des bras de stabilisation (8-9) n'a pas encore été transmis.there is therefore created between the vertical axis (3) of the pendulum (4) and the vertical axis (2) of the vehicle (l) a non-zero angle 3 (7c). At this time the order to act on the mechanism of the stabilization arms (8-9) has not yet been transmitted.
La figure 6 représente ce qui se passe à l'instant t5. Figure 6 shows what is happening at time t5.
Le système de gestion électronique de l'angle a a reçu l'information selon laquelle un angle a3 (7c) non nul vient d'apparaîte. il a transmis au mécanisme des bras de stabilisation (8-9) l'ordre de modifier les longueurs Li (12) et L2 (13), c'est à dire de redresser l'engin (1) afin de ramener l'angle 3 (7c) à la valeur nulle.The electronic angle management system a has received information that a non-zero angle a3 (7c) has just appeared. he transmitted to the mechanism of the stabilization arms (8-9) the order to modify the lengths Li (12) and L2 (13), that is to say to straighten the machine (1) in order to bring back the angle 3 (7c) to zero.
Pendant ce temps le pendule (4) est revenu à la verticale réelle en se déportant d'un angle additionnel a4 (7d).During this time the pendulum (4) returned to the real vertical by moving away from an additional angle a4 (7d).
La figure 7 représente ce qui se passe à l'instant t6. Figure 7 shows what is happening at time t6.
Selon le même principe qu'à instant t5 immédiatement précédent le système de gestion électronique de l'angle c' a reçu l'information selon laquelle un angle 4 (7d) non nul vient de se créer entre la verticale (2) de l'engin (1) et la verticale (3) du pendule (4). il a à nouveau transmis au mécanisme des bras de stabilisation (8-9) l'ordre de modifier les longueurs Ll (12) et L2 (13), c'est à dire de redresser encore l'engin (l) afin de ramener l'angle a4 (7d) à la valeur nulle.According to the same principle as at instant t5 immediately preceding the electronic management system of the angle c 'received the information according to which a non-zero angle 4 (7d) has just been created between the vertical (2) of the machine (1) and the vertical (3) of the pendulum (4). it again transmitted to the mechanism of the stabilization arms (8-9) the order to modify the lengths L1 (12) and L2 (13), that is to say to straighten the machine again (l) in order to bring back the angle a4 (7d) at zero.
A ce moment le véhicule (l) est complètement sorti de la courbe, un angle ax additionnel n'apparaît plus. L'axe vertical de l'engin (l), celui (3) du pendule (4) et la verticale réelle se confondent. Le véhicule (1) est redressé, la somme algébrique de tous les an est nulle.At this moment the vehicle (l) is completely out of the curve, an additional ax angle no longer appears. The vertical axis of the machine (l), that (3) of the pendulum (4) and the real vertical merge. The vehicle (1) is rectified, the algebraic sum of every year is zero.
Les 7 étapes représentée par les figures l à 7 ne sont que des motnents caractéristiques d'une évolution du véhicule. Dans la pratique, une étape similaire se produit tous les x centième de seconde au gré de l'évolution de l'engin (1). The 7 stages represented by FIGS. 1 to 7 are only characteristic features of an evolution of the vehicle. In practice, a similar step occurs every x hundredths of a second as the craft evolves (1).
La figure 8 est une vue de côté du véhicule (l). Le bras de stabilisation (9) (comme l'autre bras de stabilisation (8) non représenté sur cette vue) se déplace dans un mouvement oscillant autour de son axe (14) en phase avec l'inclinaison de la verticale (3) du pendule (4). Figure 8 is a side view of the vehicle (1). The stabilization arm (9) (like the other stabilization arm (8 not shown in this view) moves in an oscillating movement around its axis (14) in phase with the inclination of the vertical (3) of the pendulum (4).
Selon une variante illustrée par la figure 9 les bras de stabilisation (8-9) peuvent être réalisés comme constituant les deux côtés d'un triangle dont la base est le plan du sol (6) et dont le sommet mobile autour d'un axe (15) qui se déplace sur un arc de cercle (16) permet l'inclinaison du véhicule (1). According to a variant illustrated in FIG. 9, the stabilization arms (8-9) can be made as constituting the two sides of a triangle whose base is the ground plane (6) and whose vertex is movable around an axis (15) which moves on an arc (16) allows the vehicle (1) to be tilted.
Selon cette invention il est possible de réaliser des véhicules de la largeur d'un scotter mais en supprimant les inconvénients, énoncés plus haut, inhérent à ce type d'engins, alors qu'ils en conserveront tous les avantages, à savoir notamment le très faible encombrement. According to this invention it is possible to produce vehicles the width of a scotter but by eliminating the drawbacks, stated above, inherent in this type of machine, while they will retain all the advantages, namely in particular the very small footprint.
ils pourront être conduit par tous, car il n'est plus besoin de maîtriser l'équilibre de l'engin, et ce dans des conditions de sécurité et de confort inconnues jusqu'S ce jour pour un "deux roues". En effet du fait de sa stabilité assistée ce type de véhicule peut être réalisé autour d'une coque fermée comme une automobile classique. De plus il pourra disposer d'un volant et non plus d'un guidon et d'un confortable siège et non plus d'une selle, qui étaient nécessaires pour entrainer l'inclinaison du véhicule. they can be driven by all, because there is no longer any need to control the balance of the machine, and this under conditions of safety and comfort unknown hitherto for a "two wheeler". In fact, because of its assisted stability, this type of vehicle can be produced around a closed hull like a conventional automobile. In addition it may have a steering wheel and no longer a handlebar and a comfortable seat and no longer a saddle, which were necessary to cause the vehicle to tilt.
Selon une variante non illustrée il est également possible de gérer l'assiette de véhicules à stabilité statique, comme une automobile par exemple. According to a variant not illustrated, it is also possible to manage the attitude of vehicles with static stability, such as an automobile for example.
En effet, pour les véhicules à trois, quatre roues et plus, la stabilité à l'arrêt est parfaite. Par contre lorsqu'ils sont en mouvement dans une courbe, le centre d'inertie des ces engins tend, du fait de la force centrifuge et proportionnellement à celle-ci, à se déplacer vers l'extérieur du polygone de sustentation et ainsi à les déséquilibrer. Indeed, for vehicles with three, four wheels and more, the stability when stationary is perfect. On the other hand when they are moving in a curve, the center of inertia of these machines tends, due to the centrifugal force and proportional to this, to move towards the outside of the support polygon and thus to the unbalance.
Selon cette variante, n'utilisant pas le mécanisme des bras de stabilisation, le pendule devra être libre dans tous les axes du plan horizontal afin de mesurer les forces latérales mais aussi longitudinales qui s'exercent sur le véhicule. Selon cette variante le système de mesure-gestion de l'angle o' agira directement sur les organes de suspension de chaque roue du véhicule afin de réduire au maximum l'angle a mais non plus de l'annuler systématiquement. According to this variant, not using the mechanism of the stabilization arms, the pendulum must be free in all the axes of the horizontal plane in order to measure the lateral but also longitudinal forces which are exerted on the vehicle. According to this variant, the angle measurement-management system o 'will act directly on the suspension members of each wheel of the vehicle in order to reduce the angle a as much as possible but no longer to cancel it systematically.
