Abstract

A device for positioning at least one adjustment device, in particular for motor vehicle seats, is proposed which can be moved into a predeterminable set position by means of a control circuit. This control circuit is fed an electrical auxiliary variable for reducing the control deviation so as to achieve switching-off of the adjustment device, preferably constructed as an actuator motor (21, 22), before the set position is reached. By means of the overtravel of the adjustment device (21, 22) as a result of the inertia mass, the desired set position is then reached exactly and hunting is avoided. In this process, this electrical auxiliary variable is preferably dependent on the adjustment speed of the adjustment device.

Description

INSTALLATION POUR POSITIONNER AU MOINS UN DISPOSITIF
DE MANOEUVRE, NOTAMMENT POUR SIEGES DE VEHICULES AUTOMOBILES
L'invention a pour objet une installation pour positionner au moins un dispositif de manoeuvre, notamment pour sièges de véhicules automobiles, ce dispositif étant déplaçable au moyen d'un circuit de réglage dans une position de consigne prédéterminée.INSTALLATION FOR POSITIONING AT LEAST ONE DEVICE
MANEUVERING, ESPECIALLY FOR MOTOR VEHICLE SEATS
The invention relates to an installation for positioning at least one operating device, in particular for motor vehicle seats, this device being movable by means of an adjustment circuit in a predetermined set position.

On connait déjà une installation de ce type d'après les documents DE-OS 27 34 264 ou
DE-OS 28 18 806. Dans cette installation, les divers mouvements de manoeuvre d'un siège de véhicule automobile sont assurés par des servo-moteurs. Ur.e position de consigne est prédéterminde par un circuit de réglage, ce circuit modifiant la position réelle dans la direction de la position de consigne et coupant le servo-moteur en cas de coincidence de réglage. En raison de l'inertie de masse du servo-moteur et des organes mécaniques qui y sont raccordés, le mouvement ne peut cependant pas être arrêté de façon brutale, mais se poursuit encore d'une certaine quantité au-delà de la position de consigne.Etant donné qu'il se produit ainsi un nouvel écart de réglage, il y a risque d'oscillations de réglage ou de réglage imprécis de la position voulue du siège. We already know an installation of this type from DE-OS documents 27 34 264 or
DE-OS 28 18 806. In this installation, the various operating movements of a motor vehicle seat are provided by servo motors. Ur.e setpoint position is predetermined by an adjustment circuit, this circuit modifying the actual position in the direction of the setpoint position and switching off the servo-motor in the event of adjustment coincidence. Due to the mass inertia of the servo motor and the mechanical components connected to it, however, the movement cannot be stopped abruptly, but still continues for a certain amount beyond the set position. .Since there is a new adjustment deviation, there is a risk of imprecise adjustment oscillations or adjustment of the desired seat position.

L'invention a pour but d'éviter cet inconvénient et concerne, à cet effet, une installation du type ci-dessus caractérisée en ce qu'une grandeur électrique auxiliaire peut être envoyée au circuit de réglage pour réduire l'écart de réglage. The invention aims to avoid this drawback and relates, for this purpose, an installation of the above type characterized in that an auxiliary electrical quantity can be sent to the adjustment circuit to reduce the adjustment difference.

Par rapport aux réalisations connues, l'installation conforme à l'invention a pour avantage que, par la superposition d'une grandeur auxiliaire pour réduire l'écart de réglage, l'équilibre de réglage est atteint plus t8t et que le servo-moteur est coupé avant que la position de consigne soit atteinte. Cette coupure prématurée est déterminée de manière que le servo-moteur continue, en raison de son inertie de masse, à tourner jusqu'à la position de consigne proprement dite. Compared with known embodiments, the installation according to the invention has the advantage that, by superimposing an auxiliary quantity to reduce the adjustment deviation, the adjustment equilibrium is reached more t8t and that the servo-motor is cut before the setpoint position is reached. This premature shutdown is determined so that the servo motor continues, due to its mass inertia, to rotate to the actual set position.

Des dispositions indiquées dans la-suite permettent d'obtenir des modes de réalisation avantageux et des perfectionnements de l'installation conforme à l'invention. Ii est particulièrement avantageux que la grandeur électrique auxiliaire pour réduire l'écart de réglage soit choisie en fonction de la vitesse de manoeuvre. On garantit ainsi, pour toutes les vitesses de déplacement, que la position de consigne désirée désirée soit exactement atteinte. Cette grandeur électrique auxiliaire peut être avantageusement obtenue par formation de la différentielle de la grandeur électrique correspondant à la position réelle. Provisions indicated in the following make it possible to obtain advantageous embodiments and improvements of the installation according to the invention. It is particularly advantageous that the auxiliary electrical quantity for reducing the adjustment deviation is chosen as a function of the operating speed. This guarantees, for all travel speeds, that the desired desired setpoint position is exactly reached. This auxiliary electrical quantity can advantageously be obtained by forming the differential of the electrical quantity corresponding to the actual position.

L'invention sera mieux comprise en regard de la description ci-après et du dessin unique annexé représentant un exemple de réalisation de l'invention, au moyen d'un schéma par blocs de cet exemple. The invention will be better understood with reference to the description below and to the single appended drawing representing an exemplary embodiment of the invention, by means of a block diagram of this example.

Dans l'exemple de réalisation représenté, une borne 10 reliée au pale positif d'une source de tension d'alimentation est raccordée, par l'intermédiaire de deux organes de commutation de positionnement 11, 12 agencés sous forme dstinterrupteurs i boutons-poussoirs à deux entrées, à un module de mémoire et de commande 13. En outrv, la borne 10 est reliée, par l'intermédiaire d'un organe de commutation de mémoire 14, au module de mémoire et de commande 13.Deux sorties de valeur de consigne 15, 16, associées aux organes de commutation de positionnement 11, 12 sont reliées, par ltintermédiaire d'étages comparateurs 17, 18 et de régulateurs 19, 20, aux dispositifs de manoeuvre 21, 22 agencés sous forme de servo-moteurst
En fonction de la position des dispositifs 21, 22, une position réelle est prélevée par l'intermédiaire d'un potentiomètre, non représenté de façon particulière, et le signal de valeur réelle correspondant est envoyé aux étages comparateurs 17, 18.In the embodiment shown, a terminal 10 connected to the positive blade of a supply voltage source is connected, by means of two positioning switching members 11, 12 arranged in the form of switches i push buttons with two inputs, to a memory and control module 13. In addition, terminal 10 is connected, by means of a memory switching device 14, to the memory and control module 13. Two value outputs of setpoint 15, 16, associated with the positioning switching members 11, 12 are connected, via comparator stages 17, 18 and regulators 19, 20, to the operating devices 21, 22 arranged in the form of a servo motor.
Depending on the position of the devices 21, 22, an actual position is taken by means of a potentiometer, not shown in a particular way, and the corresponding actual value signal is sent to the comparator stages 17, 18.

L'installation décrite jusqu'ici est connue d'après l'état de la technique indiqué dans le préambule, auquel on fait expressément référence ici. Le module de mémoire et de commande 13 peut, bien entendu, être réalisé au choix sous forme de circuit discret ou de micro-calculatrice. De même, les étages comparateurs 17, 18 ainsi que les régulateurs 19, 20 peuvent être contenus dans une telle micro-calculatrice. The installation described so far is known from the state of the art indicated in the preamble, which is expressly referred to here. The memory and control module 13 can, of course, be produced as desired in the form of a discrete circuit or a micro-calculator. Likewise, the comparator stages 17, 18 as well as the regulators 19, 20 can be contained in such a micro-calculator.

I,es valeurs réelles correspondant aux positions réelles des dispositifs de manoeuvre 21, 22 sont envoyées, de plus, aux étages comparateurs 17, 18 par l'intermédiaire d'organes de différentiations 23, 24. I, the real values corresponding to the real positions of the operating devices 21, 22 are also sent to the comparator stages 17, 18 by means of differentiation members 23, 24.

Suivant l'état de la technique indiqué, le stockage des positions de consigne dans le module de mémoire et de commande est effectué en actionnant l'organe de commutation de mémoire 14 et ensuite l'un des organes de commutation de positionnement 11, 12. Si l'on doit ensuite atteindre l'une des positions mises en mémoire, il suffit d'actionner l'un des organes de commutation de positionnement 11,- 12, ce qui fait que la valeur de consigne en mémoire est appliquée à la sortie de valeur de consigne correspondante 15, 16. Le dispositif de manoeuvre associé 21 ou 22 se met ensuite en mouvement pour faire varier la position réelle dans la direction de la position de consigne. According to the state of the art indicated, the storage of the setpoint positions in the memory and control module is carried out by actuating the memory switching member 14 and then one of the positioning switching members 11, 12. If one of the positions stored in memory must then be reached, it is sufficient to actuate one of the positioning switching members 11, - 12, which means that the setpoint value in memory is applied to the output of corresponding setpoint value 15, 16. The associated operating device 21 or 22 then sets in motion to vary the actual position in the direction of the setpoint position.

Par formation de la différentielle de la grandeur électrique correspondant à la position réelle, on obtient un signal électrique correspondant à la vitesse de manoeuvre, ce signal étant envoyé en tant que grandeur auxiliaire à l'étage comparateur 17, 18. Cette gran- deur auxiliaire provoque une réduction de l'écart de réglage et donc une diminution de la différence entre la valeur de consigne et la valeur réelle. il en résulte une compensation de réglage d'un temps fonction de la vitesse avant que soit atteinte la position de consigne proprement dite. Le dispositif de manoeuvre correspondant 21, 22 est coupé et continue encore à se déplacer, par suite de sa masse d'inertie en mouvement, jusqu'à la position de consigne désirée.By forming the differential of the electrical quantity corresponding to the actual position, an electrical signal is obtained corresponding to the operating speed, this signal being sent as an auxiliary quantity to the comparator stage 17, 18. This auxiliary magnitude causes a reduction in the adjustment deviation and therefore a reduction in the difference between the setpoint and the actual value. this results in compensation for adjusting a time depending on the speed before the actual setpoint position is reached. The corresponding operating device 21, 22 is cut and still continues to move, owing to its mass of inertia in motion, to the desired setpoint position.

Pour cela, la grandeur auxiliaire est établie en fonction de la vitesse de manière à correspondre à la durée de la poursuite du mouvement. La position est ainsi atteinte de façon très précise et on évite les oscillations de réglage. For this, the auxiliary quantity is established as a function of the speed so as to correspond to the duration of the continuation of the movement. The position is thus reached very precisely and the adjustment oscillations are avoided.
