Abstract

An inner end of the gear lever (6) is linked to the device (4,5) which transmits the gear lever's movement to the gearbox. This end of the lever carries a magnet (7). A plate (8) is located underneath the end of the lever. The plate carries a number of switches (11,12,13,14) which are sensitive to the magnetic field generated by the magnet. They are positioned under the positions that the end of the lever attains when the various gears are selected. The switches are connected in parallel to a visual or sonic alarm device. The switches are of flexible blade type. ADVANTAGE - Enables unacceptable gear selections to be detected to activate alarm and/or to prevent unacceptable gear selections.

Description

L'invention concerne un dispositif permettant de détecter la position et/ou le changement de position d'un levier de manoeuvre tel que le levier de changement de vitesse d'un véhicule automobile. The invention relates to a device for detecting the position and / or the change of position of an operating lever such as the gear shift lever of a motor vehicle.

Ce dispositif permet, soit d'afficher une information concernant la vitesse enclenchée, soit de détecter une manoeuvre non autorisée du levier de vitesses en vue de commander une alerte et/ou un dispositif interdisant le démarrage du véhicule, soit d'assurer simultanément ces fonctions. This device makes it possible either to display information concerning the gear engaged, or to detect an unauthorized operation of the gear lever in order to control an alert and / or a device preventing the starting of the vehicle, or to simultaneously perform these functions .

Pour ce faire, l'invention propose de disposer, sous l'extrémité du levier de vitesses reliée au dispositif de transmission de mouvement à la boîte de vitesses, dans un plan parallèle au plan de déplacement de ladite extrémité et suivant les axes de déplacement de celle-ci autour de sa position neutre, une pluralité d'interrupteurs sensibles au champ magnétique créé par un aimant porté par ladite extrémité. To do this, the invention proposes to have, under the end of the gear lever connected to the movement transmission device to the gearbox, in a plane parallel to the plane of movement of said end and along the axes of movement of the latter around its neutral position, a plurality of switches sensitive to the magnetic field created by a magnet carried by said end.

Dans un mode de réalisation, les interrupteurs sont disposés au droit de chacune des positions occupées par l'extrémité du levier de manoeuvre lorsque la poignée dudit levier est actionnée pour sélectionner l'un des rapports de la boîte de vitesses. In one embodiment, the switches are arranged in line with each of the positions occupied by the end of the operating lever when the handle of said lever is actuated to select one of the ratios of the gearbox.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, pour la compréhension de laquelle on se reportera aux dessins annexés, dans lesquels
- la figure 1 représente un levier de manoeuvre équipé
selon l'invention,
- la figure 2 est un schéma électrique d'un circuit
d'alerte conforme à l'invention. Other characteristics and advantages of the invention will appear on reading the detailed description which follows, for the understanding of which reference will be made to the accompanying drawings, in which
- Figure 1 shows an operating lever equipped
according to the invention,
- Figure 2 is an electrical diagram of a circuit
alert according to the invention.

Dans l'exemple représenté figure 1, un levier de manoeuvre 1 est articulé sur un plancher 2 de véhicule automobile par une rotule 3. Il transmet, ainsi qu'il est connu, des mouvements de coulissement et de rotation à un organe de la boîte de vitesse (non représentés), par l'intermédiaire d'un système de bielles et d'articulations. On a représenté ici un fragment d'une telle bielle 4 et une articulation élastique 5 liée à l'extrémité du levier 1. In the example shown in Figure 1, an operating lever 1 is articulated on a floor 2 of a motor vehicle by a ball joint 3. It transmits, as is known, sliding and rotational movements to a member of the box speed (not shown), through a system of connecting rods and joints. There is shown here a fragment of such a connecting rod 4 and an elastic articulation 5 linked to the end of the lever 1.

Selon l'invention, l'axe 6 de l'articulation 5 porte un aimant 7, fixé sur ledit axe par tout moyen approprié (collage, encliquetage...). Une platine 8 est disposée sous l'extrémité inférieure du levier 1, parallèlement au plan de déplacement de ladite extrémité, lors des manoeuvres du levier, elle porte quatre interrupteurs 11, 12, 13, 14, capables de changer d'état en fonction de l'influence du champ magnétique créé par l'aimant 7. Ces interrupteurs sont, par exemple, du type à lames souples, communément appelés ILS. According to the invention, the axis 6 of the articulation 5 carries a magnet 7, fixed to the said axis by any appropriate means (bonding, snap-fastening, etc.). A plate 8 is disposed under the lower end of the lever 1, parallel to the plane of movement of said end, during the operations of the lever, it carries four switches 11, 12, 13, 14, capable of changing state as a function of the influence of the magnetic field created by the magnet 7. These switches are, for example, of the type with flexible blades, commonly called ILS.

L'exemple décrit concerne l'une des applications du dispositif conçue pour signaler la manoeuvre, non autorisée, du levier de vitesses et constituer ainsi l'élément ou l'un des éléments d'un système antivol. Dans ce cas, les interrupteurs 11, 12, 13, 14, sont disposés selon des positions équidistantes autour de la position occupée par l'axe 6 lorsque le levier 1 est au point mort et, de préférence, selon les axes de déplacement de celui-ci lorsque la poignée 9 est actionnée selon la flèche F1 de sélection, puis selon la flèche F2 de passage de vitesse, pour enclencher l'un des rapports de la boîte. The example described relates to one of the applications of the device designed to signal the unauthorized operation of the gear lever and thus constitute the element or one of the elements of an anti-theft system. In this case, the switches 11, 12, 13, 14, are arranged in equidistant positions around the position occupied by the axis 6 when the lever 1 is in neutral and, preferably, along the axes of movement of that -this when the handle 9 is actuated according to the arrow F1 for selection, then according to the arrow F2 for shifting, to engage one of the ratios of the gearbox.

Dès que l'aimant 7 se déplace ainsi au droit de l'un des interrupteurs, celui-ci change d'état, ce qui actionne en conséquence un dispositif d'alerte 15 disposé dans le circuit.  As soon as the magnet 7 thus moves in line with one of the switches, the latter changes state, which consequently activates an alert device 15 arranged in the circuit.

Comme représenté sur la figure 2, lorsque le dispositif est utilisé comme antivol, un seul système d'alerte visuelle et/ou sonore 15 est branché en parallèle sur les interrupteurs, il se déclenche lors de toute manoeuvre du levier 1. As shown in FIG. 2, when the device is used as an anti-theft device, a single visual and / or audible alert system 15 is connected in parallel with the switches, it is triggered during any operation of the lever 1.

A ce système d'alerte peut être adjoint ou substitué un dispositif permettant d'interdire le fonctionnement du véhicule.To this alert system can be added or substituted a device to prohibit the operation of the vehicle.

Dans une variante, non représentée du dispositif, un interrupteur est placé sur la platine 8 au droit de chacune des positions de l'axe 6 correspondant à l'une des vitesses sélectionnée par le levier de manoeuvre, chacun de ces interrupteurs est associé à un indicateur représentant le rapport de vitesse correspondant. Cette indication se trouve ainsi activée lorsque ledit rapport est enclenché. In a variant, not shown of the device, a switch is placed on the plate 8 in line with each of the positions of the axis 6 corresponding to one of the speeds selected by the operating lever, each of these switches is associated with a indicator representing the corresponding gear ratio. This indication is thus activated when said report is engaged.

Bien entendu, il est possible d'associer les deux fonctions d'alerte et d'indication de rapport sélectionné, de même le nombre d'interrupteurs n'est pas limitatif.  Of course, it is possible to combine the two alert functions and selected report indication, likewise the number of switches is not limiting.
