Description
La présente invention a pour objet un dispositif de prévention des accidents, notamment des accidents résultant de la collision de véhicules routiers. The present invention relates to a device for preventing accidents, including accidents resulting from the collision of road vehicles.
On ait que les accidents routiers font chaque année un grand nombre de victimes et résultent, pour la plupart, de collision entre des véhicules roulant<B>à</B> des vitesses plus ou moins importantes. It is true that road accidents cause a large number of casualties each year and most of them result in a collision between vehicles traveling at speeds of greater or lesser magnitude.
un premier objet de l'invention est de pallier cet inconvénient en évitant les chocs. Pour ce faire, il est nécessaire d'attirer l'attention du conducteur le fait qu' contact risque de se produire. a first object of the invention is to overcome this disadvantage by avoiding shocks. To do this, it is necessary to draw the attention of the driver that contact may occur.
Selon l'invention, le dispositif de prévention accidents monte sur un véhicule, muni d'un compteur de vitesse et d'un thermomètre, est caractérisé en ce qu'il comprend un microprocesseur, dont les entrées sont connectées<B>à</B> des capteurs et qui prend en compte les différents paramètres, les combine pour générer une valeur instantanée qui est comparée<B>à</B> une valeur de référence contenue dans une mémoire, et, si la valeur instantanée captée est supérieure <B>à</B> la valeur de référence, déclenche des signaux d'alarme. According to the invention, the accident prevention device mounted on a vehicle, provided with a speedometer and a thermometer, is characterized in that it comprises a microprocessor, the inputs of which are connected <B> to </ B> sensors and which takes into account the different parameters, combines them to generate an instantaneous value which is compared to a reference value contained in a memory, and, if the instantaneous value is higher than </ b> B> to </ B> the reference value, triggers alarm signals.
Les compteurs de vitesse numériques<B>,</B> reliés<B>à</B> la boite de vitesse sont connus et sont également connus des détecteurs de pluie servant<B>à</B> commander le fonctionnement des essuie- glace, de même que les détecteurs de température extérieure au véhicule. The digital speed counters <B>, </ B> connected to the gearbox are known and are also known rain detectors serving to control the operation of the wipers. - ice, as well as the temperature sensors outside the vehicle.
Selon une autre caractéristique de l'invention, le dispositif comprend de plus un capteur de distance permettant de mesurer la distance entre le véhicule concerné et un véhicule précédent. Cette mesure est, bien entendu combinée avec les autres paramètres. Dans un premier temps, lors de la mise en route du contact moteur, les mesures de température et d'humidité sont mesurées périodiquement et mises en mémoire puis le dispositif prend en compte, en permanence la vitesse (variable) du véhicule et explore par exemple au mo yen d'un télémètre Laser Infrarouge l'espace avant du véhicule. Si il existe un obstacle, fixe ou mobile, les rayons laser sont réflechis et traités dans le microprocesseur. According to another characteristic of the invention, the device further comprises a distance sensor for measuring the distance between the vehicle concerned and a previous vehicle. This measurement is, of course, combined with the other parameters. Firstly, when starting the engine contact, the temperature and humidity measurements are measured periodically and stored and the device takes into account, constantly the speed (variable) of the vehicle and explores for example by means of an Infrared Laser range finder the front space of the vehicle. If there is an obstacle, fixed or mobile, the laser beams are reflected and processed in the microprocessor.
Selon encore une autre caractéristique de l'invention, une entree du microprocesseur est reliée<B>à</B> un circuit inhibiteur du système d'alarme lorsque le clignotant est en fonctionnement. Le microprocesseur prend également en compte le fait que les feux anti brouillard sont allumés ou non pour calculer la distance de freinage convenable. According to yet another characteristic of the invention, an input of the microprocessor is connected to an inhibitor circuit of the alarm system when the flashing light is in operation. The microprocessor also takes into account whether the fog lights are on or off to calculate the proper braking distance.
Selon l'invention, un microprocesseur reçoit des informations météorologiques et des informations sur la présence d'obstacles fixes ou mobiles qui sont combinées avec la vitesse instantanée du véhicule et un signal d'alarme en cas de risque de collision. According to the invention, a microprocessor receives meteorological information and information on the presence of fixed or moving obstacles which are combined with the instantaneous speed of the vehicle and an alarm signal in case of risk of collision.
D'autres caractéristiques et avantages l'invention apparaitront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement<B>à</B> titre d'exemple non limitatif, en regard dessins qui représente sur figure unique le schéma par blocs du dispositif selon l'invention. Other features and advantages of the invention will become apparent from the following description of a particular embodiment, given only <B> to </ B> by way of non-limiting example, with reference to drawings which represents FIG. unique block diagram of the device according to the invention.
La mise en marche par la clé de contact outre ses fonction habituelles provoque l'alimentation électrique d'un étage<B>1</B> dont les sorties sont connectées respectivement<B>à</B> un détecteur de pluie 2 ou plus généralement d'humidité et<B>à</B> un thermomètre<B>3</B> délivrant un signal numérique de température. Ces deux étages sont connectés en sortie<B>à</B> une mémoire d'un microprocesseur<B>7</B> qui les combine pour donner une valeur atmosphérique<B>A</B> qui sera modifiée en fonction des variations de ces paramètres. Cette valeur<B>A</B> sera prise en compte par le microprocesseur pour évaluer l'adhérence du véhicule sur le sol et, par suite les distances de freinage. Sur une autre entrée du microprocesseur est connecté une sortie numérique du compteur de vitesse<B>5.</B> Sur une quatrième entrée du microprocesseur est branchée la sortie d'un télémetre laser directionnel infrarouge<B>6</B> qui monté sur l'avant du véhicule. The ignition by the ignition key in addition to its usual functions causes the power supply of a stage <B> 1 </ B> whose outputs are connected respectively <B> to </ B> a rain detector 2 or more generally humidity and <B> to </ B> a thermometer <B> 3 </ B> delivering a digital temperature signal. These two stages are connected at the output <B> to </ B> a memory of a microprocessor <B> 7 </ B> which combines them to give an atmospheric value <B> A </ B> which will be modified according to variations of these parameters. This value <B> A </ B> will be taken into account by the microprocessor to evaluate the adhesion of the vehicle on the ground and, consequently, the braking distances. On another input of the microprocessor is connected a digital output of the speedometer <B> 5. </ B> On a fourth input of the microprocessor is connected the output of a directional infrared laser telemeter <B> 6 </ B> which mounted on the front of the vehicle.
Une entrée du microprocesseur<B>7</B> est connectée a étage<B>8</B> qui inhibe le fonctionnement des moyens d'alarme visuelle et/ou sonore<B>10,11</B> si l'indicateur de changement du direction, est en fonctionnement avec allumage feux clignotants d'un côté ou de l'autre du véhicule. L'étage<B>8</B> est egalement connecté au dispositif de commande des feux anti brouillard de manière<B>à</B> ce que le microprocesseur calcule une nouvelle distance de freinage inférieure<B>à</B> la distance de freinage en cas de visibilité normale Le fonctionnement du dispositif est le suivant: <B>-</B> lors du départ du véhicule, les étages 2 et<B>3</B> sont alimentés et détectent les paramètres de pluie et de temperature et, éventuellement de verglas. Ces paramètres sont transmis au microprocesseur<B>7</B> qui les analyse pour déterminer une valeur de synthèse. Simultanément, le microprocesseur<B>7</B> reçoit une valeur numérique de la vitesse et, si un obstacle se trouve devant le véhicule un signal indiquant la distance<B>à</B> laquelle se trouve lobstacle. La combinaison de ces différents paramètres donne une valeur instantanée. A microprocessor input <B> 7 </ B> is connected to a stage <B> 8 </ B> which inhibits the operation of the visual and / or audible alarm means <B> 10,11 </ B> if direction indicator, is in operation with flashing lights on either side of the vehicle. The <B> 8 </ B> stage is also connected to the fog lamp control unit so that the microprocessor calculates a new lower braking distance <B> to </ B>. > the braking distance in case of normal visibility The operation of the device is as follows: <B> - </ B> when leaving the vehicle, stages 2 and <B> 3 </ B> are powered and detect the parameters rain and temperature and possibly ice. These parameters are passed to the microprocessor <B> 7 </ B> which analyzes them to determine a summary value. Simultaneously, the microprocessor <B> 7 </ B> receives a numerical value of the speed and, if an obstacle is in front of the vehicle a signal indicating the distance <B> to </ B> which is the obstacle. The combination of these different parameters gives an instantaneous value.
En fonction de cette valeur instantanée, le microprocesseur décide, par comparaison avec la valeur de référence R, s'il convient d'alerter ou non le conducteur. Si l'obstacle est suffisamment éloigné par rapport au véhicule, il se passe rien. Si l'obstacle est constitué par un autre véhicule roulant<B>à</B> la même vitesse<B>,</B> il ne se passe rien. Par contre, si le véhicule précédent roule<B>à</B> une vitesse inférieure<B>à</B> celle du véhicule considéré, le microprocesseur<B>7</B> émettra un signal d'alerte par l'intermédiaire des signaux<B>-10</B> ou<B>11</B> dès que la distance entre les deux véhicules devient inférieure <B>à</B> la distance de freinage. Le conducteur du second véhicule ainsi alerté devra réduire sa vitesse en freinant pour eviter tout risque de collision. According to this instantaneous value, the microprocessor decides, by comparison with the reference value R, whether or not to warn the driver. If the obstacle is far enough away from the vehicle, nothing happens. If the obstacle is made by another vehicle running <B> at </ B> the same speed <B>, nothing happens. On the other hand, if the preceding vehicle rolls <B> to </ B> a speed <B> to </ B> that of the considered vehicle, the microprocessor <B> 7 </ B> will emit an alert signal by the intermediate of <B> -10 </ B> or <B> 11 </ B> signals as soon as the distance between the two vehicles becomes <B> less than the braking distance. The driver of the second vehicle thus alerted will have to reduce his speed by braking to avoid any risk of collision.
Selon une autre caractéristique de l'invention, la mise en marche d'un indicateur de changement de direction signalé au microprocesseur<B>7</B> par l'étage<B>8</B> inhibe le fonctionnement du dispositif d'alarme. En effet, pour doubler un second véhicule, le conducteur du premier véhicule doit mettre en marche son clignotant pour indiquer qu'il va se déporter (ce n'est malheureusement pas toujours le cas) Au cours de cette manoeuvre, le véhicule pénètre dans champ de collision ce qui, sans cette précaution déclencherait le déclenchement des alarmes. Par ailleurs, cette disposition oblige le conducteur<B>à</B> activer son clignotant lorsqu'il veut procéder<B>à</B> un dépassement. According to another characteristic of the invention, the start of a direction change indicator signaled to the microprocessor <B> 7 </ B> by the stage <B> 8 </ B> inhibits the operation of the device. 'alarm. Indeed, to double a second vehicle, the driver of the first vehicle must turn on its flashing to indicate that it will move away (this is unfortunately not always the case) During this maneuver, the vehicle enters the field collision, which without this precaution would trigger the alarms. In addition, this provision forces the driver <B> to </ B> activate his flashing when he wants to proceed <B> to </ B> an overtaking.
Il va de soi que de nombreuses variantes peuvent être apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de 'invention.It goes without saying that many variants can be made, in particular by substituting equivalent technical means, without departing from the scope of the invention.
