Abstract

The system has two speed sensors (3,4) respectively mounted on an accelerator pedal (1) and a brake pedal (2). A calculator (5) connected to the two sensors, directs a speed of movement of a foot on the accelerator pedal and a time of movement of the foot from the accelerator pedal to the brake pedal, to a braking system (6). The system (6) carries out an emergency braking.

Description

La présente invention concerne un dispositif de freinage d'urgence d'unThe present invention relates to an emergency braking device for a

ensemble mécanique notamment d'un véhicule automobile.  mechanical assembly in particular of a motor vehicle.

Lors d'une situation d'urgence, la réaction du conducteur d'un véhicule est le freinage. Cependant, on observe que ce freinage est insuffisant.  In an emergency, the reaction of the driver of a vehicle is braking. However, it is observed that this braking is insufficient.

Certains systèmes d'aide au freinage d'urgence déjà développés, propose de déclencher une assistance de freinage en fonction de atteinte ou non d'un fixe de variation de pression dans le circuit hydraulique de freinage. Un autre système de freinage d'urgence basé sur la détection de la vitesse de la pédale de frein qui est comparé à un seuil de référence.  Some emergency braking assistance systems already developed, offer to initiate braking assistance depending on whether or not a fixed pressure variation in the hydraulic braking circuit has been reached. Another emergency braking system based on the detection of the speed of the brake pedal which is compared to a reference threshold.

La présente invention propose d'améliorer l'assistance de freinage.  The present invention proposes to improve the braking assistance.

Le système d'analyse de freinage d'urgence d'un véhicule propose un capteur (3) qui mesure la vitesse de relâchement de la pédale d'accélérateur (1) ainsi que la vitesse de déplacement de la pédale d'accélérateur (1) à la pédale de frein (2) connectée à un capteur (4) Le capteur (3) et le capteur (4) sont relié à un calculateur(5). Le calculateur(5) est relié à l'assistance de freinage(6) comme le montre le dessin fig. 1.  The emergency braking analysis system of a vehicle offers a sensor (3) which measures the speed of release of the accelerator pedal (1) as well as the speed of movement of the accelerator pedal (1) to the brake pedal (2) connected to a sensor (4) The sensor (3) and the sensor (4) are connected to a computer (5). The computer (5) is connected to the braking assistance (6) as shown in the drawing fig. 1.

Si le relâchement de la pédale d'accélérateur (1) est trop rapide en fonction d'un seuil de référence, le capteur (3) donne l'information au calculateur (5)qui à son tour transmet à l'assistance de freinage (6).  If the release of the accelerator pedal (1) is too fast according to a reference threshold, the sensor (3) gives information to the computer (5) which in turn transmits to the braking assistance ( 6).

Selon la rapidité en fonction d'un seuil de référence du relâchement de la pédale d'accélérateur (1), puis du contact avec la pédale de frein (2) avec son enfoncement, le calculateur (5) donne l'ordre de freinage à l'assistance de freinage (6). L'ordre de freinage doit être en fonction de la rapidité du mouvement en fonction d'un seuil de référence de relâchement de la pédale d'accélérateur (1) puis la rapidité du mouvement de la pédale d'accélérateur.(1) à la pédale de frein (2) avec son enfoncement en fonction d'un seuil d'urgence. Le calculateur (5) doit savoir en permanence la vitesse du véhicule puisque plus la vitesse est importante plus le freinage doit être important. Le système peut être couplé aux feux de détresse et commander leur fonctionnement des lors qu'il y a une situation de freinage d'urgence.  According to the speed as a function of a reference threshold of the release of the accelerator pedal (1), then of the contact with the brake pedal (2) with its depressing, the computer (5) gives the braking order to the brake assist (6). The braking order must be a function of the speed of movement as a function of a reference threshold for releasing the accelerator pedal (1) and then the speed of movement of the accelerator pedal. brake pedal (2) with its depressing according to an emergency threshold. The computer (5) must constantly know the speed of the vehicle since the higher the speed the more the braking must be important. The system can be coupled to the hazard warning lights and control their operation as soon as there is an emergency braking situation.

Si le mouvement n'est pas rapide, le freinage se fait normalement par l'enfoncement de la pédale de frein (2) qui est relié à l'assistance de frein (6) par une tige de fer (7).  If the movement is not rapid, braking is normally done by depressing the brake pedal (2) which is connected to the brake assistance (6) by an iron rod (7).
