Abstract
Description
- 1 - Description La présente invention concerne un dispositif pour permettre aux véhicules automobiles des particuliers ou de compétition d'aborder et d'exécuter des virages dans de meilleures conditions de sécurité et de rapidité.The present invention relates to a device for allowing private motor vehicles or racing vehicles to approach and execute turns in better conditions of safety and speed.
Traditionnellement les véhicules abordent les virages en effectuant un freinage en amont et dans la première partie de la courbe, puis une accélération dans la seconde partie ou sortie de virage. Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique un système de freinage auxiliaire permettant à une des roues et une seule de l'arrière du véhicule, celle du coté ou se situe le virage a effectuer d'être freinée. Ceci aura pour effet de faire virer le véhicule plus rapidement et dans de meilleures conditions de sécurité. En fonction de l'orientation que le pilote applique aux roues, la pression de serrage des plaquettes de frein du système auxiliaire va évoluer. Pour des problèmes de sécurité ce système ne se substitue pas au circuit de freinage classique mais il en est complémentaire ; ce même système est applicable pour les véhicules électriques.Traditionally vehicles approach turns by braking upstream and in the first part of the curve, then an acceleration in the second part or corner exit. The device according to the invention overcomes this disadvantage. It comprises in fact according to a first characteristic an auxiliary braking system allowing one of the wheels and only one of the rear of the vehicle, the one on the side where is the turn to perform to be braked. This will have the effect of turning the vehicle faster and in safer conditions. Depending on the orientation that the driver applies to the wheels, the clamping pressure of the brake pads of the auxiliary system will change. For safety problems this system does not replace the conventional braking system but it is complementary; this same system is applicable for electric vehicles.
Un codeur ou un système analogue se situe sur la colonne de direction ou un organe de transmission de mouvement d'orientation des roues et permet de connaître le sens du virage (virage à droite ou à gauche). De part la position du volant le codeur connaît l'orientation que le conducteur applique aux roues par l'intermédiaire du volant et cela avec précision. Ces deux paramètres sont transmis au système de calcul de l'ordinateur de bord du véhicule ainsi que le paramètre de vitesse du véhicule. - 2 - Description Le codeur actionne le système de calcul qui analyse le sens que le pilote applique aux roues ainsi que leur orientation, en déduction le système de calcul donne une pression en fonction de l'intensité du virage et de la vitesse du véhicule.An encoder or similar system is located on the steering column or a wheel orientation motion transmission member and provides the direction of the turn (right or left turn). Due to the position of the steering wheel the encoder knows the orientation that the driver applies to the wheels via the steering wheel and that precisely. These two parameters are transmitted to the computer system of the on-board computer of the vehicle as well as the speed parameter of the vehicle. - 2 - Description The encoder activates the calculation system which analyzes the direction that the pilot applies to the wheels as well as their orientation, as a deduction the calculation system gives a pressure according to the intensity of the turn and the speed of the vehicle.
Le circuit de freinage possède deux électrovannes permettant de sélectionner la roue arrière droite ou gauche Le système possède sont propre groupe de mise en pression du circuit de freinage et le système de calcul actionne une des deux électrovannes permettant de sélectionner la roue arrière droite ou gauche qui est sollicitée. Le système de calcul possède une base de données près établie définissant la roue et l'effort à exercer en fonction du virage et de la vitesse du véhicule.The brake system has two solenoid valves for selecting the right or left rear wheel. The system has its own brake system pressurizing unit and the calculation system operates one of the two solenoid valves to select the right or left rear wheel. is asked. The calculation system has an established database defining the wheel and the effort to be exerted according to the turn and speed of the vehicle.
Les dessins annexés illustrent l'invention : La figure 1 représente le principe de fonctionnement du système de freinage. La figure 2 représente un principe de courbe pour l'effort de freinage en fonction de la valeur des virages et de la vitesse.The accompanying drawings illustrate the invention: FIG. 1 represents the operating principle of the braking system. Figure 2 shows a curve principle for the braking force as a function of the value of the turns and the speed.
La figure 3 représente un système de mise en pression par l'intermédiaire d'un moteur électrique et un système vis écrou. En référence à ces dessins le dispositif comporte un codeur (figl rep 1) fixé sur la colonne de direction ou à un autre endroit de la chaîne cinématique. Ce codeur détermine l'orientation des roues que le pilote applique grâce au volant. Celui-ci en déduit également le sens du virage (virage à droite où virage à gauche). Ces valeurs sont transmises au système de calcul de l'ordinateur de bord du véhicule (figl rep2) ainsi que la vitesse enregistrée par le capteur (figl rep3). - 3 - Description L'ordinateur pilote la mise en pression du système auxiliaire (figl rep4) et pilote l'électrovanne concernée (figl rep2 ou rep5). L'électrovanne (figl rep5) est sollicité si roue gauche et électrovanne (figl rep4) sollicité si roue droite. La mise sous pression s'effectue de la même manière que le système standard de freinage avec maître cylindre et piston sauf que ce piston est mu par un moteur électrique et un mécanisme vis écrou (fig3). Un capteur de pression (figl repC) est relié à l'ordinateur de bord pour vérifier et contrôler que le système a bien atteint la consigne.Figure 3 shows a pressurizing system via an electric motor and a screw nut system. With reference to these drawings the device comprises an encoder (figl rep 1) fixed on the steering column or at another point in the drive train. This encoder determines the orientation of the wheels that the driver applies through the steering wheel. He also deduces the direction of the turn (right turn or left turn). These values are transmitted to the calculation system of the on-board computer of the vehicle (figl rep2) as well as the speed recorded by the sensor (figl rep3). - 3 - Description The computer controls the pressurization of the auxiliary system (figl rep4) and controls the solenoid valve concerned (figl rep2 or rep5). The solenoid valve (figl rep5) is solicited if left wheel and solenoid valve (figl rep4) solicited if right wheel. The pressurization is carried out in the same way as the standard brake system with master cylinder and piston except that this piston is driven by an electric motor and a screw nut mechanism (fig3). A pressure sensor (figl repC) is connected to the on-board computer to check and verify that the system has reached the set point.
Au fur à mesure que le pilote tourne le volant la pression du circuit augmente (fig2) jusqu'à environ la valeur médiane du virage puis redescend jusqu'à zéro lorsque le volant retrouve sa position d' origine. Le principe vis écrou permet de faire varier la pression et de mettre le système à une pression zéro lorsque les roues et le volant se trouvent en orientation neutre. Pour faciliter le pilotage ce système est inopérant pour les faibles courbes, la marche arrière et les faibles vitesses. Ceci pour faciliter le contrôle du véhicule lors du stationnement où des 20 manoeuvres. 25As the pilot turns the steering wheel the circuit pressure increases (fig2) to about the median value of the turn and then back down to zero when the steering wheel returns to its original position. The screw nut principle allows to vary the pressure and to put the system at zero pressure when the wheels and the steering wheel are in neutral orientation. For ease of control this system is inoperative for low curves, reverse gear and low speeds. This is to facilitate control of the vehicle when parking or maneuvering. 25
