Selon un mode de réalisation de l'invention, l'utilisateur modifie la position du levier primaire en appuyant sur des touches déclenchant le positionnement de celui-ci sur les positions "reverse", "neutral", vitesse 1, vitesse 2, vitesse 3, vitesse 4, ou "drive".According to one embodiment of the invention, the user modifies the position of the primary lever by pressing keys triggering the positioning of the latter in the "reverse", "neutral" positions, speed 1, speed 2, speed 3 , speed 4, or "drive".
Selon un mode de réalisation de l'invention l'autorisation de démarrer n'est donnée que si le levier primaire est en position parking ou "neutral".According to one embodiment of the invention, the authorization to start is only given if the primary lever is in the parking position or "neutral".
L'invention sera mieux comprise à la lecture de la description suivante d'un mode de réalisation particulier de l'invention, en liaison avec les dessins annexés sur lesquels: - la figure 1 situe l'implantation des leviers de commande
sur une boîte de vitesses automatique, - la figure 2 illustre la course du levier primaire de
commande, - la figure 3 est une vue de face de la carte électronique
de commande de l'invention, - la figure 4 est une vue en coupe de la carte introduite
dans sa fente de lecture. The invention will be better understood on reading the following description of a particular embodiment of the invention, in conjunction with the appended drawings in which: - Figure 1 shows the location of the control levers
on an automatic gearbox, - Figure 2 illustrates the travel of the primary lever of
order, - Figure 3 is a front view of the electronic card
control of the invention, - Figure 4 is a sectional view of the card inserted
in its reading slot.
La boîte de vitesses automatiques 1 représentée sur la figure 1 présente un levier de commande primaire 2 pivotant autour du point d'articulation 3 sur le carter 4 de celle-ci. Sur le levier primaire 2 s'articule le levier secondaire de relais 5, qui est déplacé en translation par le vérin électrique pas à pas 6 monté sur le carter 4.The automatic gearbox 1 shown in FIG. 1 has a primary control lever 2 pivoting around the point of articulation 3 on the casing 4 thereof. On the primary lever 2 is articulated the secondary relay lever 5, which is moved in translation by the electric jack step by step 6 mounted on the casing 4.
La figure 2 illustre la fonction de commande du levier primaire 2 en faisant apparaître, vis-à-vis du débattement angulaire de celui-ci les positions de fonctionnement habituelles d'une boîte de vitesses automatique. On reconnaît les positions "reverse" (R), parking (P), "neutral" (N), vitesse 1 (1), vitesse 2 (2), vitesse 3 (3), vitesse 4 (4), et "drive" (D).Figure 2 illustrates the control function of the primary lever 2 by showing, vis-à-vis the angular displacement thereof the usual operating positions of an automatic gearbox. We recognize the positions "reverse" (R), parking (P), "neutral" (N), speed 1 (1), speed 2 (2), speed 3 (3), speed 4 (4), and "drive "(D).
La carte électronique 7 représentée sur la figure 3 présente à sa partie inférieure un code barre 8. Ce code permet la reconnaissance de la carte 7 par le véhicule, et assure sa connexion. En se reportant à la figure 4, on voit que le code barre 8 est localisé dans la partie de la carte 7 pénétrant à l'intérieur ~ de la fente de lecture 9. La fente de lecture 9, intégrée à l'habitacle peut être ménagée sur une console à proximité du volant, sur le tableau de bord, ou sur un satellite. La figure 4 montre également que la carte 7 est maintenue dans la fente de lecture 9, à l'aide d'un système d'agrafe souple amovible 10 en prise sur son bord supérieur 11.The electronic card 7 shown in Figure 3 has at its lower part a bar code 8. This code allows the recognition of the card 7 by the vehicle, and ensures its connection. Referring to Figure 4, we see that the bar code 8 is located in the part of the card 7 penetrating inside ~ of the reading slot 9. The reading slot 9, integrated into the passenger compartment can be provided on a console near the steering wheel, on the dashboard, or on a satellite. FIG. 4 also shows that the card 7 is held in the reading slot 9, using a removable flexible staple system 10 engaged on its upper edge 11.
Sur la face avant de la carte 6, on trouve des touches correspondant aux positions de fonctionnement habituelles de fonctionnement d'une boîte de vitesses automatique mentionnées plus haut : R, P, N, 1,2,3, 4, D. On the front of the card 6, there are keys corresponding to the usual operating positions for the operation of an automatic gearbox mentioned above: R, P, N, 1,2,3, 4, D.
La carte présente en outre une touche de contrôle C, une touche de mise en marche du moteur M, et une touche d'arrêt du moteur k
Le fonctionnement du dispositif est le suivant:
Un conducteur se préparant à conduire le véhicule doit en premier lieu introduire sa carte 7 dans la fente de lecture 9, puis composer son code d'utilisateur. Si la carte 7 et le code utilisateur sont reconnus par le véhicule ce dernier pourra être mis en route. On peut envisager bien entendu que la carte 7 puisse être utilisée par différents utilisateurs possédant chacun un code différent, reconnu par le véhicule.The card also has a control button C, an engine start button M, and an engine stop button k
The operation of the device is as follows:
A driver preparing to drive the vehicle must first insert his card 7 into the reading slot 9, then dial his user code. If the card 7 and the user code are recognized by the vehicle, the latter can be started. It can of course be envisaged that the card 7 can be used by different users, each having a different code recognized by the vehicle.
fl est intéressant de prévoir que la composition du code sur le clavier soit assortie d'un test d'état éthylique. A l'issue de ce test, consistant par exemple à composer son code utilisateur dans des conditions de durée déterminées, le système autorisera la mise en service du véhicule ou la refusera s'il établit que l'état éthylique du conducteur est incompatible avec la conduite automobile. It is interesting to foresee that the composition of the code on the keyboard is accompanied by an ethyl state test. At the end of this test, consisting for example of dialing the user code under specified duration conditions, the system will authorize the vehicle to be put into service or refuse it if it establishes that the driver's alcohol status is incompatible with the car driving.
Dans tous les cas on peut prévoir que le dispositif laisse la possibilité à l'utilisateur d'effectuer un second essai.In all cases it can be provided that the device leaves the possibility for the user to carry out a second test.
Le démarrage du véhicule s'effectue ensuite en appuyant sur la touche de contrôle C puis sans relâcher oelle-ci, sur la touche de mise en marche du moteur M. Un microprocesseur 12, intégré à la carte 7 exerce une fonction d'aide mémoire, en déclenchant automatiquement des opérations de contrôle et de surveillance sur l'ensemble du véhicule notamment au moment de l'appui sur la commande de la touche de contrôle. On peut prévoir par exemple que le démarrage ne soit autorisé que lorsque le levier est en position neutral N ou parking P. The vehicle is then started by pressing the control key C then without releasing it, on the engine start key M. A microprocessor 12, integrated into the card 7 performs a memory aid function , by automatically triggering control and monitoring operations on the entire vehicle, in particular when the command on the control button is pressed. It can for example be provided that starting is only authorized when the lever is in the neutral N or P parking position.
La boîte de vitesses se commande ensuite en sélectionnant le mode de fonctionnement retenu, comme sur un véhicule équipé d'un levier manuel classique. L'utilisateur modifie à volonté la position du levier primaire en appuyant sur les touches R,
N, 1, 2, 3, 4, ou D. The gearbox is then controlled by selecting the operating mode selected, as on a vehicle fitted with a conventional manual lever. The user can change the position of the primary lever at will by pressing the R keys,
N, 1, 2, 3, 4, or D.
