Abstract

A transmitter and receiver unit is positioned at each of the four extremities of a motor vehicle. The transmitter transmits a wave at a predetermined angle and the wave is reflected by an obstacle for return to the receiver. The receivers provide signals for a central unit inside the vehicle. This provides a reading of distance from the obstacle. Audible and visual signals are activated within a predetermined and adjustable range from the obstacle. These operate with increasing urgency as the distance decreases to allow the vehicle driver to stop the particular manoeuvre.

Description

       

  Système de détection d'obstacle pour véhicule automobile. 

  
La présente invention concerne les véhicules automobiles et a pour but d'aider le conducteur à mieux percevoir l'encombrement de son véhicule et, de ce fait, de faciliter ses manoeuvres.

  
L'invention trouve son application dans les voitures, les automobiles tractant une caravane ou une remorque;, les camionettes et les camions, les poids lourds et les longs véhicules, et est particulièrement avantageuse pour des manoeuvres sur une aire de chargement. 

  
Le système de détection suivant l'invention est caractérisé en ce qu'il consiste en un appareillage électronique comportant, d'une part, un émetteur d'onde et, d'autre part, un récepteur de l'onde projetée et renvoyée par un obstacle, ledit appareillage étant pourvu d'un système de lecture de la distance parcourue par l'onde renvoyée et

  
de moyens de signalisation visuels et/ou auditifs entrant en action pour une distance prédéterminée.

  
Suivant l'invention, l'appareillage est constitué d'un certain nombre d'éléments, par exemple quatre, à placer aux extrémités du véhicule, chaque élément comportant un émetteur et un récepteur, et d'une centrale disposée à l'intérieur du véhicule et renfermant le système de lecture et les moyens de signalisation.

  
L'invention est décrite maintenant sur la base du dessin annexé, à titre d'exemples uniquement, montrant des cas d'application. On voit en :  Figure 1 l'application de l'invention lors d'un dépassement sur route  Figure 2 l'application de l'invention lors d'un chargement sur une aire de chargement ; Figure 3 l'application de l'invention lors du parcage d'un véhicule entre deux autres véhicules.

  
Le système détecteur suivant l'invention est constitué d'un appareillage projetant par son émetteur une onde à une certaine distance, suivant un angle déterminé.

  
L'onde se projetant sur un obstacle est renvoyée par celui-ci vers le récepteur de l'appareillage. A ce moment ledit récepteur prévient la centrale, installée à l'intérieur du véhicule, que ledit véhicule est à une certaine distance de l'obstacle.

  
La centrale étant constituée de moyens de signalisation visuels et auditifs, une fois une distance prédéterminée X atteinte - distance entre véhicule et obstacle la centrale émet un son et un voyant s'allume.

  
Ces opérations s'effectuent bien entendu en un temps extrêmement court, afin que le conducteur ait le temps de réagir, d'arrêter sa manoeuvre lors d'un parcage, d'un chargement ou d'un dépassement.

  
L'appareillage du système détecteur comporte quatre éléments 1, dotés chacun d'un émetteur et d'un récepteur, produisant et respectivement recevant les ondes. Ces éléments sont placés aux quatre extrémités du véhicule

  
2 (figure 1). On voit que, au moment où le véhicule 2 veut dépasser le véhicule 2', un autre véhicule 2" est déjà en train de doubler et reste invisible à cause de l'angle mort. Le système détecteur, par son élément 1d, prévient

  
le conducteur du danger, afin qu'il suspende sa manoeuvre

  
de dépassement.

noeuvres en ville dans les encombrements.

  
Dans la figure 3 les manoeuvres pour garer son véhicule 2 entre deux autres véhicules 2', 2", ou pour ressortir de ce parcage, sont fortement facilitées par le système détecteur suivant l'invention. Ici, les quatre éléments 1 sont utiles pour une série de petites manoeuvres

  
 <EMI ID=3.1> 

  
Le système détecteur suivant l'invention présente encore l'avantage de contrôler l'espace entre le véhicule et le véhicule précédant, afin de permettre au conducteur de maintenir la distance utile de freinage.

  
Il présente encore l'avantage de prévenir, par un avertisseur sonore, un conducteur somnolent de l'écart dangereux qu'il ferait sur une route, vers un mur, un véhicule ou tout autre obstacle. 

REVENDICATIONS

  
1. Système de détection d'obstacle pour véhicule automobile, caractérisé en ce qu'il consiste en un appareillage électronique comportant, d'une part, un émetteur d'onde et, d'autre part, un récepteur de l'onde projetée et renvoyée par un obstacle, ledit appareillage étant pourvu d'un système de lecture de la distance parcourue par l'onde renvoyée et de moyens de signalisation visuels et/ou auditifs entrant en action pour une distance prédéterminée.



  Obstacle detection system for a motor vehicle.

  
The present invention relates to motor vehicles and aims to help the driver to better perceive the size of his vehicle and, therefore, to facilitate its maneuvers.

  
The invention finds its application in cars, automobiles towing a caravan or a trailer;, vans and trucks, heavy goods vehicles and long vehicles, and is particularly advantageous for maneuvers on a loading area.

  
The detection system according to the invention is characterized in that it consists of an electronic apparatus comprising, on the one hand, a wave transmitter and, on the other hand, a receiver of the wave projected and returned by a obstacle, said apparatus being provided with a system for reading the distance traveled by the returned wave and

  
visual and / or auditory signaling means coming into action for a predetermined distance.

  
According to the invention, the apparatus consists of a certain number of elements, for example four, to be placed at the ends of the vehicle, each element comprising a transmitter and a receiver, and a central unit disposed inside the vehicle and containing the reading system and the signaling means.

  
The invention is now described on the basis of the appended drawing, by way of examples only, showing application cases. We see in: Figure 1 the application of the invention when overtaking on the road Figure 2 the application of the invention when loading on a loading area; Figure 3 the application of the invention when parking a vehicle between two other vehicles.

  
The detector system according to the invention consists of an apparatus projecting by its transmitter a wave at a certain distance, at a determined angle.

  
The wave projecting on an obstacle is returned by this one towards the receiver of the apparatus. At this moment said receiver warns the central station, installed inside the vehicle, that said vehicle is at a certain distance from the obstacle.

  
The control unit being made up of visual and auditory signaling means, once a predetermined distance X is reached - distance between vehicle and obstacle, the control unit emits a sound and an indicator light comes on.

  
These operations are of course carried out in an extremely short time, so that the driver has time to react, to stop his maneuver during parking, loading or overtaking.

  
The apparatus of the detector system comprises four elements 1, each provided with a transmitter and a receiver, producing and respectively receiving the waves. These elements are placed at the four ends of the vehicle

  
2 (Figure 1). We see that, when vehicle 2 wants to overtake vehicle 2 ', another vehicle 2 "is already overtaking and remains invisible because of the blind spot. The detector system, by its element 1d, prevents

  
the driver of the danger, so that he stops his maneuver

  
overshoot.

  
In figure 2 the delivery truck 3 must enter a limited space 4 to an area

  
 <EMI ID = 1.1>

  
elements, will allow the driver to reach this loading area without bumping against the walls of the restricted space and against the area itself.

  
The detector system particularly helps

  
 <EMI ID = 2.1>

  
city works in congestion.

  
In FIG. 3, the maneuvers for parking one's vehicle 2 between two other vehicles 2 ′, 2 ", or for emerging from this parking area, are greatly facilitated by the detector system according to the invention. Here, the four elements 1 are useful for a series of small maneuvers

  
 <EMI ID = 3.1>

  
The detector system according to the invention also has the advantage of controlling the space between the vehicle and the preceding vehicle, in order to allow the driver to maintain the useful braking distance.

  
It also has the advantage of warning, by an audible warning, a drowsy driver of the dangerous distance he would make on a road, towards a wall, a vehicle or any other obstacle.
