Description

1 Dispositif de commande électrique La présente invention concerne un1 Electrical control device The present invention relates to a

dispositif de commande, en particulier pour véhicule automobile comprenant un organe de commande mobile en rotation. Actuellement, les véhicules automobiles sont équipés de plus en plus avec des systèmes électroniques d'assistance et de confort pour le conducteur et ses passagers. Alors qu'il y a un certain nombre d'années, rares étaient par exemple les véhicules équipés en même temps d'un système de climatisation et d'un système de navigation, ces systèmes sont en train de se démocratiser et sont accessibles à un plus grand nombre de personnes et proposés ensemble déjà pour certaines versions de base.  control device, in particular for a motor vehicle comprising a movable control member in rotation. Currently, motor vehicles are increasingly equipped with electronic systems of assistance and comfort for the driver and his passengers. While a few years ago, for example, there were few vehicles equipped with air conditioning and a navigation system at the same time, these systems are becoming more accessible and accessible to a number of people. more people and proposed together already for some basic versions.

De plus, les systèmes électroniques sont améliorés constamment et offrent de plus en plus de paramètres de réglage. Ainsi, les systèmes audio comportent maintenant pratiquement tous différents groupes de haut parleurs dont on peut régler la balance gauche/ droite et avant / arrière. Les systèmes radio permettent des réglages pour des recherches rapides en fonction du programme diffusé ou selon que la station diffuse ou non des messages sur l'état du trafic de la région parcourue. Pour les systèmes de climatisation, on a vu récemment apparaître la gestion des réglages des paramètres de la climatisation par zones. Tous ces systèmes nécessitent des moyens de commande adaptés qui soient ergonomiques et faciles d'utilisation. Pour faciliter les commandes dans un véhicule automobile et diminuer le nombre de commandes individuelles, des commandes multifonctions associées à un écran d'affichage ont fait leur apparition dans le domaine automobile. Ces commandes connues ont par exemple la forme d'une manette de commande ou joystick permettant de naviguer dans un menu affiché à l'écran. La sélection d'une fonction choisie se réalise par exemple par un appui sur l'élément de préhension de la commande. De plus, on a doté ce joystick d'un organe rotatif de commande qui permet par exemple d'augmenter ou de diminuer le volume d'un système audio lorsque cette fonction de réglage du volume a été choisie. SFR5067 2903220 2 Ainsi, avec une seule commande multifonctions, on arrive à commander une multitude de systèmes électroniques et de fonctions dans un véhicule automobile. Du fait du nombre de fonctions pouvant être commandées, ce joystick devient une interface privilégiée du conducteur. Il en résulte que l'extrémité libre de ce joystick devient un emplacement aussi important pour la 5 marque du véhicule que par exemple le volant. Or, sur les dispositifs de commande multifonction connus dans l'état de la technique, en apposant par exemple un logo sur cette extrémité, le logo tourne, ce qui n'est pas souhaitable. La présente invention vise à proposer une solution à ce problème. A cet effet, l'invention a pour objet un dispositif de commande électrique comprenant 10 • un organe de commande déplaçable selon un mouvement de rotation, et • un circuit électrique pour transformer les mouvements de l'organe en signaux de commande, caractérisé en ce que l'organe de commande comprend un élément circulaire, monté mobile en rotation et un engrenage relié en rotation d'une part à l'organe et d'autre part à l'élément 15 circulaire, mobile en rotation, et en ce que le rapport de transmission de l'engrenage est choisi de manière que la position angulaire dudit élément circulaire reste sensiblement identique indépendamment de la position angulaire de l'organe de commande ou de la rotation appliquée à celui-ci. D'autres avantages et caractéristiques apparaîtront à la lecture de la description de l'invention, ainsi 20 que sur les figures annexées sur lesquelles : • la figure 1 est une vue schématique en perspective d'un dispositif selon l'invention à l'état assemblé, et • la figure 2 est un schéma des engrenages du dispositif selon l'invention. La figure 1 montre une vue en perspective d'un dispositif de commande électrique selon 25 l'invention. Ce dispositif comprend un organe de commande 3 réalisé de préférence sous forme d'une manette de commande (également appelé joystick) dont l'extrémité libre 5 présente une partie de préhension 7 pour un utilisateur. Le dispositif selon l'invention permet d'être utilisé dans un système multifonctions de préférence avec un écran d'affichage et une unité de traitement et de gestion. Dans ce cas, le dispositif sert à commander par exemple le curseur sur un écran d'affichage et permet de sélectionner des fonctions à commander, par exemple la fonction de réglage des volumes des hauts parleurs dans un système audio. SFR5067 2903220 3 Cet organe de commande est déplaçable librement selon un mouvement de rotation (voir flèches 9 et 11 sur la figure 1). De préférence, il est en plus déplaçable librement selon un mouvement de pivotement représenté par des flèches TX et TY ainsi qu'en translation selon une direction TZ parallèle à la manette en position de repos (la figure 1 présente la manette en position de repos).  In addition, electronic systems are constantly improved and offer more and more tuning parameters. Thus, audio systems now include virtually all different groups of speakers that can be adjusted left / right and forward / backward. Radio systems allow settings for quick searches based on the program being broadcast or whether or not the station is broadcasting traffic status messages for the region being traveled. For air conditioning systems, we have recently seen the management of the settings of the air conditioning parameters by zones. All these systems require adapted control means that are ergonomic and easy to use. To facilitate orders in a motor vehicle and reduce the number of individual orders, multifunctional controls associated with a display screen have appeared in the automotive field. These known commands have for example the form of a joystick or joystick for navigating a menu displayed on the screen. The selection of a chosen function is carried out for example by pressing on the gripping element of the control. In addition, this joystick has been equipped with a rotary control device which makes it possible, for example, to increase or decrease the volume of an audio system when this volume adjustment function has been chosen. SFR5067 2903220 2 Thus, with a single multifunction control, one can control a multitude of electronic systems and functions in a motor vehicle. Because of the number of functions that can be controlled, this joystick becomes a privileged interface of the driver. As a result, the free end of this joystick becomes a location as important for the brand of the vehicle as for example the steering wheel. However, on the multifunction control devices known in the state of the art, for example by affixing a logo on this end, the logo rotates, which is not desirable. The present invention aims to propose a solution to this problem. For this purpose, the subject of the invention is an electrical control device comprising: a control member displaceable according to a rotational movement, and an electrical circuit for transforming the movements of the body into control signals, characterized in that that the control member comprises a circular element mounted rotatably and a gear connected in rotation on the one hand to the member and on the other hand to the circular member, rotatable, and in that the Transmission ratio of the gear is chosen such that the angular position of said circular member remains substantially the same regardless of the angular position of the control member or the rotation applied thereto. Other advantages and characteristics will appear on reading the description of the invention, as well as in the appended figures in which: FIG. 1 is a schematic perspective view of a device according to the invention in the state assembled, and • Figure 2 is a diagram of the gears of the device according to the invention. Figure 1 shows a perspective view of an electrical control device according to the invention. This device comprises a control member 3 preferably made in the form of a joystick (also called joystick) whose free end 5 has a gripping portion 7 for a user. The device according to the invention can be used in a multifunctional system preferably with a display screen and a processing and management unit. In this case, the device serves to control for example the cursor on a display screen and allows to select functions to control, for example the speaker volume adjustment function in an audio system. SFR5067 2903220 3 This control member is freely movable according to a rotational movement (see arrows 9 and 11 in Figure 1). Preferably, it is moreover freely movable according to a pivoting movement represented by arrows TX and TY as well as in translation in a direction TZ parallel to the handle in the rest position (FIG. 1 shows the handle in the rest position) .

5 Le dispositif selon l'invention est doté d'un circuit électrique pour transformer les mouvements de l'organe en signaux de commande. Sur la figure 1, on perçoit par exemple des interrupteurs 13 du circuit qui ferment des boucles électriques et permettent ainsi de délivrer des signaux de commande. La partie de préhension est réalisée en deux parties.The device according to the invention is provided with an electric circuit for transforming the movements of the body into control signals. In Figure 1, for example, there are switches 13 of the circuit which close electrical loops and thus deliver control signals. The gripping part is made in two parts.

10 La première partie 15 est destinée à être entraînée en rotation par l'utilisateur, par exemple à l'aide de ses doigts. Elle permet de faire par exemple défiler un menu sur un écran d'affichage. La seconde partie 17 est réalisée sous forme d'un élément circulaire, monté mobile en rotation sur la manette 3. Avantageusement, les axes de rotation de cet élément circulaire ainsi que l'axe de rotation de la manette sont confondus.The first part 15 is intended to be rotated by the user, for example by means of his fingers. It allows for example to scroll a menu on a display screen. The second part 17 is made in the form of a circular element mounted rotatably on the handle 3. Advantageously, the axes of rotation of this circular element and the axis of rotation of the joystick are merged.

15 Comme cela est représenté de façon schématique sur la figure 2, le dispositif selon l'invention comprend en outre un engrenage relié en rotation d'une part à l'organe 15 et d'autre part à l'élément circulaire 17. Le rapport de transmission de l'engrenage est choisi de manière que la position angulaire dudit élément circulaire reste sensiblement identique indépendamment de la position angulaire de l'organe de 20 commande ou de la rotation appliquée à celui-ci. Ainsi, l'utilisateur a l'impression que cette partie 17 est fixe en rotation. Ceci a pour avantage que l'élément circulaire peut être réalisé sous forme d'un logo ou autre signe distinctif ou peut porter un tel logo. Un tel logo ou signe distinctif est donc toujours présenté avec la même orientation indépendamment de la position angulaire de l'organe de commande 15.As shown diagrammatically in FIG. 2, the device according to the invention further comprises a gear connected in rotation on the one hand to the member 15 and on the other hand to the circular element 17. The ratio The transmission gear of the gear is selected so that the angular position of said circular member remains substantially the same regardless of the angular position of the control member or the rotation applied thereto. Thus, the user has the impression that this part 17 is fixed in rotation. This has the advantage that the circular element can be made in the form of a logo or other distinctive sign or can bear such a logo. Such a logo or distinctive sign is always presented with the same orientation regardless of the angular position of the control member 15.

25 De préférence l'engrenage comprend une roue dentée à deux étages 21 dont le premier étage 23 engrène avec une crémaillère 25 disposée sur le pourtour intérieur de la manette et dont le second étage 27 engrène avec le pourtour denté de l'élément circulaire mobile en rotation 17. Dans cette configuration avec un pignon à deux étages, les rayons des pignons d'engrenage remplissent la relation suivante : 30 R,*R4=(R,+R2)(R2+R3) où R, ù est le rayon de la partie dentée de l'élément circulaire R2 ù est le rayon du premier étage de la roue dentée R3 ù est le rayon du second étage de la roue dentée R.1 ù est le rayon de la crémaillère interne de l'organe de commande. SFR5067 2903220 4 On comprend donc que cette disposition selon l'invention permet d'avoir un organe rotatif de commande qui présente à l'intérieur un élément circulaire 17 dont l'utilisateur a l'impression qu'il est fixe en rotation. Même si l'invention a été expliquée en détail au regard d'une manette de commande, elle peut 5 aussi bien être réalisée avec un simple bouton rotatif dont le centre est formé par l'élément circulaire, mobile en rotation. SFR5067Preferably the gear comprises a two-stage gear 21 whose first stage 23 meshes with a rack 25 disposed on the inside periphery of the handle and whose second stage 27 meshes with the toothed periphery of the movable circular element. rotation 17. In this configuration with a two-stage gear, the spokes of the gear wheels fulfill the following relation: R, * R4 = (R, + R2) (R2 + R3) where R, where is the radius of the toothed portion of the circular element R2 ù is the radius of the first stage of the toothed wheel R3 where is the radius of the second stage of the toothed wheel R.1 where is the radius of the internal rack of the control member. SFR5067 2903220 4 It is therefore understood that this arrangement according to the invention allows to have a rotary control member which has inside a circular element 17 which the user has the impression that it is fixed in rotation. Although the invention has been explained in detail with respect to a joystick, it can be performed with a simple rotary knob whose center is formed by the circular element, rotatable. SFR5067
