Description
La présente invention concerne un système d'aide à la conduite d'un véhicule automobile. The present invention relates to a driving assistance system for a motor vehicle.
Plus particulièrement, la présente invention concerne un système d'aide qui comporte des moyens formant détecteur d'obstacle, implantés sur le véhicule et reliés à des moyens d'analyse des signaux de sortie de ceux-ci, ces moyens d'analyse étant reliés à des moyens d'indication sonore de la distance séparant le véhicule d'un obstacle (voir par exemple le document FR-A-2 452 721). More particularly, the present invention relates to an assistance system which comprises means forming an obstacle detector, installed on the vehicle and connected to means for analyzing the output signals thereof, these analysis means being connected to means for audible indication of the distance separating the vehicle from an obstacle (see for example document FR-A-2 452 721).
Ce type de systèmes a été développé dans l'état de la technique pour apporter une aide par exemple au parcage d'un véhicule ou lorsque le conducteur d'un véhicule effectue des manoeuvres délicates. This type of system has been developed in the state of the art to provide assistance, for example in parking a vehicle or when the driver of a vehicle performs delicate maneuvers.
Les moyens formant détecteur d'obstacle sont bien connus dans l'état de la technique et comportent par exemple des moyens à infrarouge, à haute fréquence, à ultrason ou à laser, et permettent par analyse des signaux délivrés par ces moyens, de déterminer la distance qui sépare le véhicule de l'obstacle. The means forming an obstacle detector are well known in the state of the art and comprise, for example, infrared, high frequency, ultrasonic or laser means, and make it possible by analysis of the signals delivered by these means, to determine the distance between the vehicle and the obstacle.
En fonction de cette distance, les moyens d'analyse pilotent les moyens d'indication sonore pour que ceux-ci émettent un son par exemple dont la fréquence est proportionnelle à la distance qui sépare le véhicule de l'obstacle et qui devient continu lorsque le véhicule est en phase de heurter l'obstacle. Depending on this distance, the analysis means control the sound indication means so that they emit a sound for example whose frequency is proportional to the distance which separates the vehicle from the obstacle and which becomes continuous when the vehicle is in the process of hitting the obstacle.
D'autres moyens d'interfaçage permettant d 'in- former le conducteur de la distance séparant le véhicule de l'obstacle ont également été décrits dans l'état de la technique, comme par exemple des moyens d'interfaçage utilisant des matrices de points, des diodes électroluminescentes ou encore des écrans d'affichage. Other interfacing means making it possible to inform the driver of the distance separating the vehicle from the obstacle have also been described in the state of the art, such as for example interfacing means using point matrices. , light emitting diodes or display screens.
On pourra également se référer au document FR-A2 716 145 qui décrit un dispositif indicateur de distance libre en particulier pour faciliter les manoeuvres d'un véhicule automobile. Reference may also be made to document FR-A2 716 145 which describes a device for indicating a free distance in particular to facilitate the maneuvers of a motor vehicle.
Cependant, tous les moyens d'interfaçage développés dans l'état de la technique présentent un certain nombre d'inconvénients, car il est souvent difficile pour l'utilisateur de localiser géographiquement l'obstacle par rapport au véhicule. En effet, celui-ci est souvent situé en dehors du champ de vision de l'utilisateur alors que ce dernier est absorbé par des tâches de conduite. However, all of the interface means developed in the state of the art have a certain number of drawbacks, since it is often difficult for the user to locate the obstacle geographically relative to the vehicle. Indeed, it is often located outside the field of vision of the user while the latter is absorbed by driving tasks.
De plus, les sons émis par les dispositifs d'indication sonore connus ne sont pas toujours très agréables à entendre en raison de leur puissance ou encore de leur tonalité. In addition, the sounds emitted by known sound indication devices are not always very pleasant to hear because of their power or their tone.
Le but de l'invention est donc de résoudre ces problèmes. The object of the invention is therefore to solve these problems.
A cet effet, l'invention a pour objet un système d'aide à la conduite d'un véhicule automobile, du type comportant des moyens formant détecteur d'obstacle, implantés sur le véhicule et reliés à des moyens d'analyse des signaux de sortie de ceux-ci, ces moyens d'analyse étant reliés à des moyens d'indication sonore de la distance séparant le véhicule d'un obstacle, le véhicule comportant également un système audiophonique comprenant des haut-parleurs répartis dans l'habitacle du véhicule, caractérisé en ce que les moyens d'indication sonore sont formés par les haut-parleurs du système audiophonique et en ce que les moyens d'analyse sont reliés à ce système, pour permettre un pilotage des haut-parleurs de celui-ci en fonction de la position de l'obstacle par rapport au véhicule et de la distance le séparant de celui-ci. To this end, the subject of the invention is a system for assisting the driving of a motor vehicle, of the type comprising means forming an obstacle detector, installed on the vehicle and connected to means for analyzing the signals of output thereof, these analysis means being connected to means for audible indication of the distance separating the vehicle from an obstacle, the vehicle also comprising an audio system comprising loudspeakers distributed in the passenger compartment of the vehicle , characterized in that the sound indication means are formed by the loudspeakers of the audiophonic system and in that the analysis means are connected to this system, to allow control of the loudspeakers of the latter as a function the position of the obstacle relative to the vehicle and the distance separating it from the latter.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels
- la Fig.l représente un schéma synoptique illustrant la structure générale d'un système d'aide à la conduite selon l'invention;
- la Fig.2 illustre de façon schématique le fonctionnement d'un tel système; et
- la Fig.3 illustre des informations de localisation d'un obstacle pouvant être délivrées à un utilisateur, sous la forme de données affichées.The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the accompanying drawings, in which
- Fig.l shows a block diagram illustrating the general structure of a driving assistance system according to the invention;
- Fig.2 schematically illustrates the operation of such a system; and
- Fig.3 illustrates obstacle location information that can be delivered to a user, in the form of displayed data.
On reconnaît sur la figure 1, un système d'aide à la conduite d'un véhicule automobile qui comporte des moyens formant détecteur d'obstacle, désignés de façon générale par la référence 1 sur cette figure, implantés sur le véhicule par exemple sur les pare-chocs avant et/ou arrière de celui-ci. Recognizing in Figure 1, a driving assistance system for a motor vehicle which comprises means forming obstacle detector, generally designated by the reference 1 in this figure, located on the vehicle for example on the front and / or rear bumper thereof.
Comme cela a été décrit précédemment, ces moyens formant détecteur d'obstacle peuvent comporter n'importe quel moyen approprié connu dans l'état de la technique. As described above, these obstacle detector means may comprise any suitable means known in the state of the art.
(voir les documents mentionnés précédemment).(see the documents mentioned above).
Ces moyens formant détecteur d'obstacle sont reliés à des moyens d'analyse des signaux de sortie de ceux-ci. These obstacle detector means are connected to means for analyzing their output signals.
Ces moyens d'analyse sont désignés de façon générale par la référence 2 sur cette figure et comportent par exemple des moyens classiques permettant de calculer la distance séparant le véhicule de l'obstacle et de déterminer la position de cet obstacle par rapport au véhicule par analyse des signaux émanant des moyens formant détecteur. These analysis means are generally designated by the reference 2 in this figure and include for example conventional means making it possible to calculate the distance separating the vehicle from the obstacle and to determine the position of this obstacle relative to the vehicle by analysis. signals from the detector means.
Dans l'état de la technique, ces moyens d'analyse sont reliés à des moyens d'indication sonore de la distance séparant le véhicule de l'obstacle. In the state of the art, these analysis means are connected to means for audible indication of the distance separating the vehicle from the obstacle.
Dans le système selon l'invention, le véhicule comporte également un système audiophonique désigné par la référence générale 3 sur cette figure, comportant des haut-parleurs répartis dans l'habitacle du véhicule et dont par exemple deux sont représentés sur cette figure 1 et désignés par les références 4 et 5. In the system according to the invention, the vehicle also comprises an audiophonic system designated by the general reference 3 in this figure, comprising loudspeakers distributed in the passenger compartment of the vehicle and of which two for example are represented in this figure 1 and designated by references 4 and 5.
Ces haut-parleurs sont par exemple disposés à l'arrière du véhicule de chaque côté de celui-ci. These speakers are for example arranged at the rear of the vehicle on each side thereof.
I1 va de soi bien entendu qu'un système comportant plusieurs paires de haut-parleurs régulièrement réparties dans l'habitacle du véhicule, peut également être envisagé. It goes without saying of course that a system comprising several pairs of speakers regularly distributed in the passenger compartment of the vehicle can also be envisaged.
Ce système audiophonique comporte également un afficheur d'informations permettant de délivrer des informations relatives par exemple aux stations reçues par ce système. This audiophonic system also includes an information display making it possible to deliver information relating for example to the stations received by this system.
Selon l'invention, les moyens d'indication sonore sont formés par les haut-parleurs du système audiophonique et les moyens d'analyse 2 sont reliés à ce système audiophonique 3 pour permettre un pilotage par exemple en puissance et/ou en fréquence des sons émis par les haut-parleurs de celui-ci, en fonction de la position de l'obstacle par rapport au véhicule et de la distance le séparant de celui-ci. According to the invention, the sound indication means are formed by the loudspeakers of the audiophonic system and the analysis means 2 are connected to this audiophonic system 3 to allow control for example of the power and / or frequency of the sounds. emitted by the speakers of the latter, as a function of the position of the obstacle with respect to the vehicle and the distance separating it from the latter.
On conçoit alors comme cela ressort de la figure 2, qu'en fonction de la localisation de l'obstacle par rapport au véhicule et de la distance séparant cet obstacle du véhicule, il est possible d'ajuster la puissance et la fréquence des sons émis par chaque haut-parleur du système audiophonique, pour indiquer à l'utilisateur que l'obstacle se situe plus à gauche ou plus à droite du véhicule en modulant la fréquence et/ou l'amplitude des sons émis par chaque haut-parleur. It can therefore be seen, as can be seen from FIG. 2, that depending on the location of the obstacle relative to the vehicle and the distance separating this obstacle from the vehicle, it is possible to adjust the power and the frequency of the sounds emitted. by each loudspeaker of the audiophonic system, to indicate to the user that the obstacle is located more to the left or more to the right of the vehicle by modulating the frequency and / or the amplitude of the sounds emitted by each loudspeaker.
On voit en effet sur cette figure 2 que si l'obstacle est situé du côté droit du véhicule, à l'arrière de celui-ci, il est possible de piloter les hautparleurs du système audiophonique embarqué à bord du véhicule, de manière que le haut-parleur 4 situé à l'arrière droit du véhicule émette un son de puissance plus importante que celui situé de l'autre côté du véhicule, afin d'indiquer à l'utilisateur que l'obstacle se situe de ce côté droit du véhicule. It can be seen in this FIG. 2 that if the obstacle is located on the right side of the vehicle, behind it, it is possible to control the loudspeakers of the audio system on board the vehicle, so that the speaker 4 located at the rear right of the vehicle emits a sound of greater power than that located on the other side of the vehicle, in order to indicate to the user that the obstacle is located on this right side of the vehicle .
La fréquence du son émis peut également être modulée de façon classique en fonction de la distance entre le véhicule et l'obstacle. The frequency of the sound emitted can also be modulated in a conventional manner as a function of the distance between the vehicle and the obstacle.
Cette information sonore peut être confirmée par une information visuelle affichée sur l'afficheur 6 du système audiophonique comme on peut le voir sur la figure 3. This audio information can be confirmed by visual information displayed on the display 6 of the audio system as can be seen in FIG. 3.
Sur cette figure, on voit en effet qu'il est possible d'afficher sur cet afficheur une information de distance séparant le véhicule de l'obstacle, par exemple 90 cm dans l'exemple illustré et un point situé quelque part sur l'afficheur en fonction de la localisation de l'obstacle par rapport au véhicule et matérialisant la présence de celui-ci. In this figure, we can see that it is possible to display on this display distance information separating the vehicle from the obstacle, for example 90 cm in the example illustrated and a point located somewhere on the display depending on the location of the obstacle relative to the vehicle and materializing the presence of the latter.
I1 va de soi bien entendu que les informations sonores et/ou visuelles délivrées à l'utilisateur peuvent être superposées ou non à des informations déjà délivrées à celui-ci, par exemple par les haut-parleurs et l'af fi- cheur du système audiophonique. It goes without saying of course that the audio and / or visual information delivered to the user may or may not be superimposed on information already delivered to the user, for example by the loudspeakers and the display of the system. audiophonic.
Bien entendu, le système d'aide à la conduite selon l'invention peut être utilisé pour détecter des obstacles à l'avant ou à l'arrière du véhicule. Of course, the driving assistance system according to the invention can be used to detect obstacles at the front or at the rear of the vehicle.
On peut également envisager l'intégration d'un tel système dans les systèmes de multiplexage embarqués à bord des véhicules automobiles, un tel système pouvant alors être associé à des écrans multi-fonctions permettant d'afficher le contexte de circulation dans lequel se trouve le véhicule, à un système de synthèse vocale pouvant délivrer à l'utilisateur des messages d'indication de la présence et de la localisation de l'obstacle ou encore à un système de contrôle d'une boîte de vitesses à commande automatique permettant d'arrêter le véhicule automatiquement lorsque le système détecte que celui-ci est en phase de heurter un obstacle, les manoeuvres se faisant toujours à très faible vitesse. We can also consider the integration of such a system in on-board multiplexing systems on board motor vehicles, such a system can then be associated with multi-function screens making it possible to display the traffic context in which the vehicle is located. vehicle, to a text-to-speech system capable of delivering messages to the user indicating the presence and location of the obstacle, or to an automatic control gearbox control system enabling the driver to stop the vehicle automatically when the system detects that it is in the process of hitting an obstacle, the maneuvers always being carried out at very low speed.
On conçoit alors que le système d'aide à la conduite selon l'invention présente un certain nombre d'avantages par rapport aux systèmes de l'état de la technique dans la mesure où il permet un bon interfaçage entre le véhicule et l'utilisateur. It is therefore conceivable that the driving assistance system according to the invention has a certain number of advantages compared with the systems of the state of the art insofar as it allows good interfacing between the vehicle and the user. .
