In addition, the present invention presents a device which has the advantage of being assembled, disassembled and reassembled at will, even on model vehicles and different brand.
A cet effet le dispositif de double commande, objet de la présente invention, agissant à la demande sur le freinage et/ou sur l'embrayage et/ou sur l'accélérateur d'un véhicule école, se caractérise essentiellement en ce qu'il comporte au moins un capteur mécanique c'est-à-dire un capteur actionnable par sollicitation mécanique, fournissant un signal électrique représentatif d'action ou sollicitation de pieds d'un utilisateur, tel le moniteur, un circuit électrique de commande, recevant par une liaison électrique le dit signal représentatif de cette action et au moins un organe moteur électrique, connecté électriquement au circuit électrique de commande et activé par ledit circuit lorsque ce dernier reçoit le signal représentatif de l'action de pied appliquée par l'utilisateur sur le capteur, ledit organe moteur électrique comportant un élément mécanique de sortie, solidaire de l'extrémité d'un élément mécanique flexible d'actionnement, fixé par son autre extrémité à la pédale de frein ou à la pédale d'embrayage ou à la pédale d'accélérateur, ledit organe de sortie appliquant un effort axial sur l'élément flexible d'actionnement lorsque l'organe moteur est activé, l'effort axial exercé sur l'élément flexible étant appliqué par ce même élément sur la pédale ce qui actionne cette dernière vers le plancher du véhicule.To this end the dual control device, object of the present invention, acting on demand on braking and / or on the clutch and / or on the accelerator of a vehicle school, is essentially characterized in that it comprises at least one mechanical sensor that is to say a sensor actuable by mechanical stress, providing a signal electrical representative of action or solicitation of a user's feet, such as the monitor, an electrical control circuit, receiving by an electrical link the said signal representative of this action and at least one electric motor member, electrically connected to the electrical control circuit and activated by said circuit when the latter receives the signal representative of the foot action applied by the user to the sensor, said electric motor member comprising a mechanical output element, integral with the end of a flexible mechanical actuating element, fixed by its other end the brake pedal or the clutch pedal or the accelerator pedal, said member output applying an axial force on the flexible actuating element when the member motor is activated, the axial force exerted on the flexible element being applied by this same element on the pedal which activates the latter towards the floor of the vehicle.
Un dispositif de simple commande électrique ayant quelques caractéristiques de la présente invention est exposé dans WO-A- 92 05 482.A simple electrical control device having some Characteristics of the present invention is set out in WO-A-92 05 482.
Le dispositif de double commande est destiné notamment à équiper un véhicule automobile d'apprentissage de la conduite automobile pour doubler efficacement les commandes de freinage, d'embrayage, et d'accélération. Ainsi l'invention selon un autre de ses aspects prévoit trois capteurs mécaniques destinés respectivement à l'activation des fonctions de freinage, d'embrayage et d'accélération du véhicule, connectés électriquement au circuit électrique de commande et fournissant des signaux représentatifs d'actions de pieds d'un utilisateur, au dit circuit électrique de commande, lequel est connecté électriquement à trois organes moteurs électriques, lesquels sont activés par ledit circuit de commande respectivement à partir de l'action sur les trois capteurs, les trois organes moteurs étant associés mécaniquement par l'intermédiaire de trois éléments flexibles d'actionnement, respectivement aux trois pédales du véhicule, lesquelles sont actionnées chacune vers le plancher du véhicule par l'élément flexible associé lorsque l'organe moteur correspondant est activé par le circuit électrique de commande.The dual control device is intended in particular to equip a vehicle learning to drive a car to effectively double brake, clutch, and acceleration controls. Thus the invention according to another of its aspects provides three mechanical sensors intended respectively for activation vehicle braking, clutch and acceleration functions, electrically connected to the electrical control circuit and providing representative signals actions of a user's feet, to said electrical control circuit, which is connected electrically to three electric motors, which are activated by said control circuit respectively from the action on the three sensors, the three motor parts being mechanically associated via three elements actuation hoses, respectively to the three pedals of the vehicle, which are each actuated towards the vehicle floor by the associated flexible element when the corresponding motor member is activated by the electrical control circuit.
Les éléments flexibles d'actionnement pourront être constitués chacun par un câble monté en coulissement dans une gaine flexible en spirales d'acier. Un tel élément flexible est connu sous le nom de câble de BOWDEN. Le câble de cet élément flexible sera par exemple fixé par une de ses extrémités à la pédale correspondante et cette dernière sera actionnée par ce câble en traction vers le plancher du véhicule.The flexible actuating elements may each be constituted by a cable slidably mounted in a flexible steel spiral sheath. Such an element flexible is known as BOWDEN cable. The cable of this flexible element will for example be fixed by one of its ends to the corresponding pedal and the latter will be actuated by this cable in traction towards the floor of the vehicle.
Selon cette forme de réalisation, à chacun des éléments flexibles d'actionnement est associé un boítier arrêt de gaine monté en pivotement sur une embase de fixation au plancher du véhicule et ce en regard et en avant de la pédale correspondante de façon à suivre le mouvement de cette dernière et permettre l'auto-orientation du câble suivant la direction de l'effort de traction sur la pédale ce qui minimise son usure.According to this embodiment, to each of the flexible actuating elements is associated with a sheath stop box pivotally mounted on a mounting base to the vehicle floor and this opposite and in front of the corresponding pedal so as to follow the movement of the latter and allow the cable to self-orient according to the direction of the traction force on the pedal which minimizes its wear.
Selon une variante d'exécution, le câble, par son extrémité libre, est fixé au plancher du véhicule, en arrière de la pédale correspondante, et cette dernière est équipée d'une bague arrêt de gaine traversée par le câble, dans laquelle est bloquée l'extrémité de la gaine. Selon cette forme de réalisation, l'élément flexible d'actionnement, entre l'organe moteur d'actionnement et la pédale correspondante, est disposé selon un trajet présentant au moins une courbe.According to an alternative embodiment, the cable, by its free end, is fixed to the floor of the vehicle, behind the corresponding pedal, and the latter is equipped a sheath stop ring crossed by the cable, in which the end of the sheath. According to this embodiment, the flexible actuating element, between the member actuation motor and the corresponding pedal, is arranged along a path having at least one curve.
Selon une première forme de réalisation, le moniteur d'auto-école dispose, pour contrôler les trois pédales, d'un bandeau de faible largeur doté de trois tampons respectivement associés mécaniquement aux trois capteurs lesquels sont fixés à ce bandeau. La consigne d'enfoncement d'une pédale est directement proportionnelle à la pression exercée par le pied du moniteur sur le tampon correspondant à la pédale d'origine laquelle conserve par ailleurs, sa fonction initiale.According to a first embodiment, the driving school instructor has, for control the three pedals, a narrow strip with three buffers respectively mechanically associated with the three sensors which are fixed to this strip. The pedal depressing setpoint is directly proportional to the pressure exercised by the monitor's foot on the pad corresponding to the original pedal which also retains its original function.
L'amplitude ou l'intensité du signal électrique délivré par chaque capteur mécanique est représentative de la valeur de la pression exercée par le pied du moniteur. L'élément de sortie de chaque organe moteur électrique est déplacé par son moteur lorsque ce dernier est activé, et la valeur de son déplacement est en corrélation avec la valeur de l'amplitude ou de l'intensité du signal électrique, délivré par le capteur mécanique.The amplitude or intensity of the electrical signal delivered by each mechanical sensor is representative of the value of the pressure exerted by the monitor foot. The element output of each electric motor member is moved by its motor when this last is activated, and the value of its displacement is correlated with the value of the amplitude or intensity of the electrical signal, delivered by the mechanical sensor.
Les capteurs mécaniques ou de mouvement de pied liés au dispositif objet de la présente invention sont donc des capteurs de pression, des capteurs d'enfoncement ou des capteurs de position.The mechanical or foot movement sensors linked to the device object of the present invention are therefore pressure sensors, penetration sensors or position sensors.
Selon une autre forme de réalisation, chaque capteur est actionné par une pédale, qui lui est propre, montée en articulation dans un support amovible, sous forme de boítier par exemple, monté sur le plancher du véhicule du côté de l'emplacement du passager avant. Ce boítier avec pédales à pour but de remplacer le bandeau sus évoqué. Selon cette forme de réalisation, chaque pédale du boítier sera montée sur un axe d'articulation supporté par une chape fixée au dit boítier. Dans le boítier, sur la trajectoire de chaque pédale, sera disposée une butée, destinée à matérialiser la fin de course. De plus la butée associée à la pédale correspondant à la pédale de frein du véhicule, est déformable élastiquement et délivre à la pédale un effort de réaction simulant l'effort exercé par le circuit de freinage sur la pédale de frein du conducteur lorsque ce dernier cherche à bloquer les roues. Le capteur associé à la pédale, délivrera dans cette situation un signal d'intensité ou d'amplitude maximale ou quasi maximale, de sorte que le moteur d'actionnement, par l'intermédiaire de l'élément flexible associé, repoussera la pédale vers le plancher, au maximum de la course de cette dernière.According to another embodiment, each sensor is actuated by a pedal, which is specific to it, mounted in a hinge in a removable support, in the form of a housing for example, mounted on the vehicle floor on the passenger side before. The purpose of this box with pedals is to replace the aforementioned headband. According to this embodiment, each pedal of the housing will be mounted on a hinge pin supported by a yoke attached to said housing. In the case, on the path of each pedal, there will be a stopper, intended to materialize the end of stroke. In addition the stop associated with the pedal corresponding to the vehicle brake pedal, is elastically deformable and delivers a reaction force to the pedal simulating the force exerted by the circuit brake on the driver's brake pedal when the driver is trying to block the wheels. The sensor associated with the pedal, will deliver in this situation an intensity signal or of maximum or almost maximum amplitude, so that the actuation motor, by through the associated flexible element, push the pedal towards the floor, at maximum travel of the latter.
A chacune des pédales du véhicule, c'est-à-dire celles destinées à être actionnées par l'élève conducteur, est associé un moyen de blocage en pivotement, activable par le moniteur, dans le but d'interdire, lorsque cela s'avère nécessaire, la manoeuvre de cette pédale vers le plancher. En variante, il n'est plus prévu un moyen de blocage de chaque pédale pour prévenir sa fausse manoeuvre par l'élève mais un vibreur, activable par le moniteur.To each of the vehicle's pedals, i.e. those intended to be actuated by the student driver, is associated a pivoting locking means, activatable by the monitor, in order to prohibit, when necessary, the operation of this pedal to the floor. As a variant, there is no longer a means for blocking each pedal to prevent mishandling by the student but a vibrator, activated by the monitor.
De préférence, chaque organe moteur électrique est un moto-réducteur. Chaque moto-réducteur comporte un treuil sur lequel s'enroule le câble de l'élément flexible de la pédale associée, ce treuil constituant l'élément de sortie de l'organe moteur électrique. A ce treuil ou à l'un des pignons du réducteur constituant transmission de mouvement entre le treuil et l'arbre du moteur, est associé un potentiomètre pour repérer la position angulaire du treuil et, par voie de conséquence, le degré d'enfoncement de la pédale.Preferably, each electric motor member is a gear motor. Each gear motor comprises a winch on which the cable of the flexible element of the associated pedal, this winch constituting the output element of the electric motor member. To this winch or to one of the pinions of the reduction gear constituting motion transmission between the winch and the motor shaft, a potentiometer is associated to identify the position angularity of the winch and, consequently, the degree of depression of the pedal.

Dans la figure 1 sont représentés un bandeau de contrôle 1 comportant trois capteurs
2, 3 et 4 et supporté par un support 5 relié au plancher du véhicule 6 ou bien directement
fixé à ce plancher, des conducteurs électriques de liaison 7, un boítier moteur 8
relié électriquement à une alimentation électrique 9 par des conducteurs électriques
d'alimentation et aux capteurs 2, 3, 4 par les conducteurs électriques 7. Par ailleurs, le
boítier moteur 8, comportant les organes moteurs électriques 22, 23, 24 est relié mécaniquement
à trois éléments mécaniques, flexibles 10, 11 et 12 constitués, par exemple chacun
par un câble de "BOWDEN". Ces câbles de " BOWDEN " sont constitués chacun
par un câble en acier monté en coulissement dans une gaine de guidage. L'élément 10 est
constitué par un câble 101 et une gaine 102. L'élément 11 est constitué par un câble 111
et une gaine 112 et l'élément 12 est constitué par un câble 121 et une gaine 122. Ces
éléments 10, 11, 12 sont respectivement engagés dans trois boítiers arrêt de gaine 13, 14
et 15 et reliés respectivement à trois pédales de conduite 16, 17 et 18. Plus précisément,
les éléments mécaniques de sortie des organes moteurs électriques reçoivent en fixation
respectivement les trois câbles 101, 111, 121 des éléments flexibles d'actionnement 10,
11, 12. Pour actionner les pédales, les éléments mécaniques de sortie des organes moteurs
électrique agissent en traction sur les câbles des éléments flexibles d'actionnement.In Figure 1 are shown a control panel 1 comprising three
Le bandeau de contrôle 1 est, pour le moniteur de l'auto-école, l'équivalent des
pédales de conduite 16, 17 et 18 pour l'élève. Les capteurs d'enfoncement ou de pression
2, 3 et 4 correspondent respectivement aux trois pédales de conduite 16, 17 et 18. Le
bandeau 1 sert ainsi à contrôler le véhicule 6 parallèlement à l'action de l'élève. Pour des
raisons ergonomiques, la distance latérale entre les capteurs 2, 3 et 4 est sensiblement
égale à celle séparant les pédales 16, 17 et 18. Le bandeau de contrôle 1 sert uniquement
de support rigide aux capteurs 2, 3 et 4 et est lui-même supporté, par exemple, par un
support 5 qui l'éloigne du plancher du véhicule 6, selon la position la plus appropriée au
confort du moniteur.The control strip 1 is, for the driving school instructor, the equivalent of
driving
Les capteurs 2, 3 et 4 sont aptes à transmettre chacun un signal électrique en
fonction de l'action du pied sur leur surface. Ces capteurs peuvent, par exemple, être des
capteurs de mouvement, par exemple à base de potentiomètres, des capteurs de force,
des capteurs de pression, des capteurs d'enfoncement ou des capteurs de position. Ils sont
de type connu. Ces capteurs sont protégés par un tampon en matière plastique ou élastique
ou encore en caoutchouc. Les capteurs 2, 3 et 4 sont chacun aptes à émettre un signal
électrique représentatif du mouvement, de la position ou de la force exercée par le pied
du moniteur sur leur surface.
Le conducteurs électriques de liaison 7 relient électriquement les capteurs 2, 3 et
4 au boítier moteur 8 et transmettent les signaux sortant des capteurs 2, 3 et 4.The electrical connecting
Le boítier moteur 8 est présenté en figure 4. Il comporte trois moto-réducteurs
commandés en fonction des signaux sortant des capteurs 2, 3 et 4 et commandant la position
des pédales de conduite 16, 17 et 18. Il reçoit donc en entrée les conducteurs électriques
de liaison 7 et l'alimentation électrique et commande, en sortie, la position des
trois câbles 101, 111, 121 des éléments flexibles 10, 11 et 12.The
L'alimentation électrique 9 est préférentiellement constituée par la batterie d'accumulateur
du véhicule 6.The
Les trois éléments mécaniques flexibles d'actionnement 10, 11, et 12 s'engagent
respectivement dans trois boítiers arrêt de gaine 13, 14 et 15. Les trois boítiers arrêt de
gaine 13, 14 et 15 sont situés respectivement en avant des pédales 16, 17 et 18 et sont
fixés sur le plancher du véhicule 6. Chaque boítier arrêt de gaine reçoit du boítier moteur
8, l'un des éléments 10, 11 ou 12 comportant la gaine externe et le câble central et il en
ressort uniquement le câble central qui est mécaniquement lié à la face inférieure de la
pédale correspondante. De cette manière, une traction exercée sur le câble central par
l'un des moto-réducteurs provoque l'enfoncement d'une des pédales de conduites 16, 17
ou 18.The three flexible
Les pédales de conduite 16, 17 et 18 sont celles d'origine du véhicule.The driving
Chaque boítier arrêt de gaine est monté en pivotement autour d'un axe 20 sur une
embase 13A de fixation au plancher 19 du véhicule et ce en regard et en avant de la pédale
correspondante. Le boítier arrêt de gaine comporte un canal interne 13B s'étendant
depuis un orifice d'introduction du câble et de sa gaine vers un orifice de sortie du câble
lequel orifice est pratiqué dans la face frontale dudit boítier, c'est-à-dire, celle disposée
en regard de la pédale. Dans le canal interne 13B du boítier sont introduits le câble et sa
gaine et cette dernière est bloquée par son extrémité dans ledit canal, contre un épaulement
de ce dernier, par exemple. L'orifice d'introduction du câble et de sa gaine est pratiqué
dans une des faces latérales du boítier cette face étant perpendiculaire à l'axe de pivotement.
Le canal interne 13B du boítier 13 se développe suivant un arc de circonférence
de cercle de rayon relativement important. L'axe 20 de pivotement du boítier 13 est
parallèle à l'axe de pivotement de la pédale correspondante et le centre géométrique de
l'orifice de sortie appartient au plan géométrique dans lequel évolue l'attache du câble à
la pédale. Ainsi le boítier, lorsque la pédale est sollicitée en traction, peut librement pivoter
et le câble s'orienter selon la direction de l'effort de traction sur la pédale, ce qui limite
l'usure par frottement sur l'arête de l'orifice de sortie. Par ailleurs le câble, de part
cette disposition, ne sera pas soumis à des efforts de cisaillement au niveau de l'orifice de
sortie. Selon ce mode de réalisation, le câble de l'élément flexible d'actionnement agit en
traction sur la pédale correspondante. Selon une variante d'exécution représentée en figure
5, le câble de l'élément flexible d'actionnement, par son extrémité libre, est fixé au
plancher du véhicule, en arrière de la pédale correspondante, et cette dernière reçoit en
fixation une bague 38 arrêt de gaine traversée par le câble, dans laquelle est bloquée
l'extrémité de la gaine de l'élément flexible. L'élément flexible d'actionnement, entre l'organe
moteur d'actionnement et la pédale correspondante, est disposé selon un trajet présentant
au moins une courbe et le dit élément est monté dans le véhicule de manière à
pouvoir s'y déplacer librement. Ainsi, lorsque l'organe moteur électrique correspondant
agit en traction sur le câble, la courbe formée par l'élément flexible peut se réduire, ce
qui force la gaine à venir en poussée sur la pédale.Each sheath stop box is pivotally mounted about an
Le moniteur d'auto-école dispose, pour contrôler les trois pédales, d'un bandeau 1 de faible largeur doté de trois tampons. La consigne d'enfoncement d'une pédale est directement proportionnelle à la pression exercée par le pied du moniteur sur le tampon correspondant à la pédale d'origine.The driving school instructor has a strip 1 to control the three pedals narrow width with three buffers. The pedal depressing instruction is directly proportional to the pressure exerted by the monitor's foot on the pad corresponding to the original pedal.
Le capteur 2 est associé fonctionnellement à la pédale de conduite 16 à l'élément
flexible d'actionnement 10. Le capteur 3 est associé fonctionnellement à la pédale de
conduite 17 et à l'élément flexible d'actionnement 11. Le capteur 4 est associé fonctionnellement
à la pédale de conduite 18 et à l'élément flexible d'actionnement 12.
Les éléments flexibles d'actionnement 10, 11 et 12 sont associés mécaniquement respectivement
aux trois boítiers arrêt de gaine 13, 14, 15.The
Dans la figure 2 sont représentés un boítier arrêt de gaine 13 comportant un axe
de pivotement 20, un élément flexible d'actionnement 10, le plancher 19 du véhicule 6 et
une pédale de conduite 16 reliée à un axe de rotation 21. On comprend que la tension du
câble de l'élément flexible d'actionnement 10 provoque la descente de la pédale de conduite
16 vers l'axe de pivotement 20.In Figure 2 are shown a
Dans la figure 3, sont représentés le boítier arrêt de gaine 13, l'axe de pivotement
20, l'élément flexible d'actionnement 10, le plancher 19 du véhicule 6 et la pédale de
conduite 16, reliée à l'axe de rotation 21. La figure 3 représente en vue de dessus les
mêmes éléments que la figure 2 et ne nécessite donc pas d'explication complémentaire.In Figure 3, are shown the casing stop
Dans la figure 4 sont représentés, dans une vue de dessus, le boítier moteur 8, les
conducteurs électriques 7, les câbles mécaniques 101, 111 et 121, l'alimentation électrique
9. Le boítier moteur 8 comporte trois organes moteurs électriques 22, 23, et 24, trois
capteurs de position 34, 35 et 36 et un circuit électrique 37 relié à tous les éléments
électriques du dispositif selon l'invention. Chaque organe moteur électrique est constitué
par exemple par un moto-réducteur et comporte un élément mécanique de sortie auquel
est fixé l'un des trois câbles mécaniques de traction 101, 111, 121. Chaque moto-réducteur
comprend un moteur électrique du type de ceux possédant un arbre de sortie
rotatif sur lequel un couple mécanique est disponible et un réducteur accouplé par bride
ou autre moyen d'accouplement à l'arbre de sortie du moteur électrique, ledit réducteur
étant pourvu d'un arbre de sortie accouplé à l'élément mécanique de sortie de l'organe
moteur. Les arbres 22A, 23A, et 24A respectifs de sortie des réducteurs sont accouplés
respectivement aux éléments de sortie 25, 26 et 27 des trois organes moteurs, lesdits
éléments de sortie étant constitués chacun par un treuil. Sur les trois treuils s'enroulent
respectivement les câbles 101, 111, 121 des éléments flexibles d'actionnement 10, 11 et
12 et entraínent donc les descentes des pédales de conduite 16, 17, et 18 respectivement.In Figure 4 are shown, in a top view, the
Chaque réducteur est constitué par exemple de deux pignons de diamètres primitifs
différents, en engrènement l'un avec l'autre, dont un est calé sur l'arbre de sortie du
moteur correspondant et l'autre sur l'arbre de sortie 22A ou 23A ou 24A correspondant, le
pignon de plus grand diamètre étant calé sur ce dernier arbre. En figure 4 on peut remarquer
que le réducteur constitué des pignons 28 et 29 est accouplé à l'arbre 22A de l'organe
moteur 22 et fourni un couple moteur au treuil 25 tandis que le réducteur constitué
des pignons 30 et 31 est accouplé à l'arbre de sortie 23A et coopère en accouplement
avec le treuil 26. On remarque également que le réducteur constitué des pignons 32 et 33
est accouplé à l'arbre 24A et coopère en accouplement avec le treuil 27.Each gearbox consists for example of two pinions of primitive diameters
different, meshing with each other, one of which is wedged on the output shaft of the
corresponding motor and the other on the
Les trois capteurs de position 34, 35 et 36 sont mécaniquement reliés aux arbres
des organes moteurs, aux pignons des réducteurs ou aux treuils. Ils sont aptes à posséder
une réponse électrique variable en fonction de leur position mécanique. Ils sont, par
exemple, constitués de potentiomètres possédant une résistance variable en fonction de
cette position ou encore des pédales de conduite.The three
Le circuit électrique 37 asservit la position de la pédale de conduite 16 en fonction
du signal lui provenant du capteur 2, en effectuant une vérification de position par le
biais du potentiomètre 34. De même, le circuit électrique 37 asservit la position de la pédale
de conduite 17 en fonction du signal lui provenant du capteur 3, en effectuant une
vérification de position par le biais du potentiomètre 35. Enfin, le circuit électrique 37
asservit la position de la pédale de conduite 18 en fonction du signal lui provenant du
capteur 4, en effectuant une vérification de position par le biais du potentiomètre 36. The
Le schéma électronique du circuit électrique 37 est connu de l'homme de l'art
dans le domaine des asservissements de position.The electronic diagram of the
Dans la forme de réalisation, objet de la figure 6, les capteurs 2, 3, 4 ne sont plus
portés par un bandeau mais montés en fixation dans un boítier 39 fixé de manière amovible
sur le plancher du véhicule côté passager et ouvert en direction du siège du passager.
Dans ce boítier, sont montées en articulation trois pédales 40, dont la première actionne
le capteur 2, la deuxième le capteur 3 et la troisième le capteur 4. Chaque pédale
40 est montée fixement sur un axe d'articulation 41 monté en rotation dans une chape 42
fixée au boítier 39. Le capteur 2 ou 3 ou 4 associé à la pédale 40 correspondante sera du
type de ceux comprenant un axe rotatif et délivrant un signal d'intensité ou d'amplitude
représentative de la position angulaire de l'axe par rapport à une position d'origine. Ce
capteur sera accouplé à l'axe d'articulation 41 pour délivrer une information représentative
de la position angulaire de la pédale associée. Chaque pédale 40 est déplaçable vers
le plancher du véhicule sous l'effet de l'action de l'effort de poussée, exercé par le pied du
moniteur. Pour ramener chaque pédale en position d'origine, est prévu un ressort de rap
pel (non représenté) monté en tension entre le boítier et la pédale.In the embodiment, object of FIG. 6, the
Les trois pédales 40 correspondent respectivement à la pédale de l'accélérateur
18, à la pédale de frein 17 et à la pédale d'embrayage 16 et sont respectivement associées
aux capteurs 4, 3 et 2. Sur la trajectoire de chaque pédale 40, est montée en fixation dans
le boítier 39, une butée destinée à matérialiser la fin de course de cette pédale. La butée
42 associée à la pédale du boítier correspondant à la pédale de frein 17, se présente sous
la forme d'un tampon tronconique et se déforme élastiquement sous l'effet de l'action de
la pédale 40 correspondante. En réaction à l'effort appliqué par la pédale 40, cette butée
42 applique sur la pédale 40, un effort de réaction simulant celui exercé par le circuit hydraulique
de freinage sur la pédale 17 lorsque cette dernière est repoussée par le conducteur
au maximum de sa course.The three
A chacune des pédales 16, 17, 18 pourra être associé un moyen de blocage en pivotement,
activable par le moniteur, dans le but d'interdire à l'élève de manoeuvrer cette
pédale lorsque cela s'avère nécessaire. Ce moyen pourra être constitué par un élément
flexible d'actionnement 43 fixé d'une part à la pédale correspondante, 16 ou 17 ou 18 et
d'autre part à un organe moteur électrique d'actionnement 44 lequel lorsqu'il est activé
agit en traction sur l'élément flexible pour maintenir la pédale correspondante par traction
sur cette dernière par l'intermédiaire du dit élément, dans la position la plus écartée
du plancher et interdire sa manoeuvre vers ce dernier. Le signal d'activation de l'organe
moteur électrique sera délivré par un capteur 45 monté en fixation contre la face inférieure
46A du tampon de manoeuvre 46 de la pédale 40. Ce capteur 45 délivrera le signal
d'activation lorsqu'il sera actionné par le pied du moniteur.Each of the
Enfin il y a lieu de noter que la mise en place du dispositif selon l'invention dans
le véhicule requiert peu de moyens matériels et se trouve ainsi facilitée. Par ailleurs,
l'usage de câble sous gaine, pour actionner les pédales du véhicule permet de placer le
boítier moteur 8 à distance des pédales dans l'emplacement le plus approprié. Ainsi ce
boítier pourra être placé sous le siège conducteur, dans le coffre à bagage du véhicule ou
tout autre emplacement disponible.Finally, it should be noted that the installation of the device according to the invention in
the vehicle requires few material means and is thus facilitated. Otherwise,
the use of cable under sheath, to actuate the pedals of the vehicle makes it possible to place the
