Etat de la technique L'invention concerne un moyen d'assistance aux manoeuvres de garage pour un véhicule automobile comportant un appareil de frein pour commander ou régler la force de freinage, au moins un capteur pour détecter la distance par rapport à un obstacle et un appareil de commande qui émet STATE OF THE ART The invention relates to a means for assisting garage maneuvers for a motor vehicle comprising a brake apparatus for controlling or adjusting the braking force, at least one sensor for detecting the distance to an obstacle and an obstacle. control device that transmits
un signal de commande en fonction de la distance détectée. a control signal as a function of the detected distance.
Selon le document DE 34 20 004 Al, on connaît déjà un dispositif de mesure de distance ou de télémétrie pour des véhicules automobiles selon lequel lorsqu'on passe en dessous d'une distance prédéterminée, il y a émission d'un signal avertisseur acoustique et/ou optique. Il peut toutefois arriver que les signaux optiques ou acoustiques ne soient pas remarqués car l'attention du conducteur est détournée par l'environnement. Il peut également arriver que le conducteur ne réagisse pas correctement malgré les signaux avertisseurs et qu'il touche ainsi l'obstacle. Il DE 34 20 004 A1 already discloses a distance measuring or telemetry device for motor vehicles according to which, when passing below a predetermined distance, an acoustic warning signal is emitted and / or optical. However, it may happen that the optical or acoustic signals are not noticed because the attention of the driver is diverted by the environment. It may also happen that the driver does not react properly despite the warning signals and that he thus touches the obstacle. he

De ce fait, le véhicule ne peut rouler de lui-même contre l'obstacle reconnu (par exemple sur un trajet en pente) ce qui évite de façon avantageuse les accidents. La manoeuvre de garage est également simplifiée car le conducteur n'a plus à agir en finesse sur le frein ou la pédale Therefore, the vehicle can not roll itself against the recognized obstacle (for example on a sloping path) which advantageously avoids accidents. The garage maneuver is also simplified because the driver no longer has to act finely on the brake or the pedal

Il est particulièrement avantageux que l'appareil de commande prédétermine la force de freinage en fonction de la distance pour avoir une force de freinage proportionnelle à la distance par rapport au véhicule. En It is particularly advantageous that the control device predetermines the braking force as a function of distance to have a braking force proportional to the distance from the vehicle. In

Lorsqu'il enlève le pied de l'accélérateur, le véhicule est immédiatement protégé sure that will decrease the distance. The driver can then only get closer to the obstacle if he increases the power supplied by accelerating. When he takes his foot off the accelerator, the vehicle is immediately protected

De façon avantageuse, pour une distance limite, minimale, prédéterminée, l'action du frein est tellement Advantageously, for a limit distance, minimum, predetermined, the action of the brake is so

Si par contre, notamment à cause de la très faible place disponible on souhaite se rapprocher très près de l'obstacle, on peut le faire avantageusement en coupant l'action sur le frein. Cela peut se faire à l'aide d'un simple commutateur qui coupe le signal de commande vers le If on the other hand, especially because of the very small space available we want to get very close to the obstacle, it can be done advantageously by cutting the action on the brake. This can be done with a simple switch that cuts the control signal to the

Le moyen d'assistance aux manoeuvres de garage selon l'invention peut être combiné avantageusement à un dispositif de commande du système antipatinage ASR car ce système ASR possède déjà une fonction agissant sur les freins. Dessins Un exemple de réalisation de l'invention est représenté aux dessins et sera décrit ci-après de manière plus détaillée. Ainsi: - la figure 1 montre un premier exemple de réalisation de l'invention. The means for assisting the garage maneuvers according to the invention can be advantageously combined with a control device of the ASR traction control system because this ASR system already has a function acting on the brakes.

Le fonctionnement de ce moyen sera décrit plus en détail à l'aide de la figure 2. L'installation de mesure de distance ou de télémétrie 2 connue en soi se compose par Mande 3 and traction control system (ASR system) 6. This line or line can be interrupted by a switch 9. The operation of this means will be described in more detail with the help of Figure 2. The distance measuring installation or telemetry 2 known per se is composed by

chocs arrière du véhicule 1 pour mesurer la distance d par rapport à un mur W. Selon la figure 2 on mesure à l'étape 11, tout d'abord la distance d. Cette distance est affichée par le moyen d'affichage 5 au cours de l'étape 12. A l'étape 13, on demande si l'interrupteur 9 coupant l'action des freins rear impact of the vehicle 1 to measure the distance d with respect to a wall W. According to Figure 2 is measured in step 11, first of all the distance d. This distance is displayed by the display means 5 during step 12. In step 13, it is asked whether the switch 9 cutting the action of the brakes

Cela correspond alors au fonctionnement des moyens d'assistance de manoeuvre de garage, connus. Si par contre, l'interrupteur 9 est fermé, on prend, à l'étape 14, la force de freinage par exemple dans le tableau d'une mémoire 21 et on applique un signal correspondant à l'appareil ASR 6 comme l'indique l'étape 15. A l'étape 16, on vérifie par This then corresponds to the operation of the known garage maneuvering assistance means. If on the other hand, the switch 9 is closed, it takes, in step 14, the braking force for example in the table of a memory 21 and applies a signal corresponding to the ASR device 6 as indicated step 15. In step 16, check by

Si cette valeur limite prédéterminée n'est pas atteinte, le programme revient en arrière et recommence à l'étape 11 par une nouvelle mesure de distance d. Par contre, si la valeur limite prédéterminée est atteinte, le véhicule s'arrête si bien qu'il ne peut plus être déplacé même si l'on poursuit If this predetermined limit value is not reached, the program goes back and starts again at step 11 by a new measurement of distance d. On the other hand, if the predetermined limit value is reached, the vehicle stops so that it can no longer be moved even if one continues
