Abstract

The passive security lighting control for a motor vehicle uses different combinations of actuation of the brake and emergency lights. The degree of braking force is detected and analyzed by a circuit board to allow four different lighting modes dependent on the degree of braking. The degree of braking force can be detected using movements of the speedometer.

Description

Amélioration de la sécurité passive pour les véhicules automobiles par modification du mode d'allumage des feux stop et / ou des feux de détresse lors de décélération .  Improvement of passive safety for motor vehicles by modifying the mode of lighting of the stop lamps and / or of the hazard warning lights during deceleration.

L'allumage des feux stop lors de la décélération des véhicules automobiles,ne permet pas d'apprécier l'importance de cette décélération dans l'état actuel de fabrication de la plupart des véhicules . The lighting of stop lamps during the deceleration of motor vehicles, does not allow to appreciate the importance of this deceleration in the current state of manufacture of most vehicles.

Proposer des allumages différents et non simultanés des feux stop ainsi que l'allumage des feux de détresse selon l'importance de la décélération, celle ci étant mesurée directement au compteur de vitesse, et non par capteurs sur la pédale de frein par exemple : une même pression sur la pédale de frein n'entrainant pas la même décélération selon les cas ( ABS ou non, montée ou descente ). Propose different and not simultaneous ignitions of the stop lamps as well as the ignition of the hazard warning lights according to the importance of the deceleration, the latter being measured directly on the speedometer, and not by sensors on the brake pedal for example: same pressure on the brake pedal does not cause the same deceleration as appropriate (ABS or not, up or down).

La décélératon mesurée au compteur de vitesse ( 1 Fig 6 ) sera analysée par une carte à puce ( 2 Fig 6 ) qui a mémorisé 4 plages de décélération, chaque type de décélération entrainant un allumage particulier des feux stop et / ou des feux de détresse . -MODE 1 FIG 2<U>Freinage normal</U> : 3 feux stop ( 3 et 4 Fig 6 ) s'allument simultanément et en continu ( modalité actuelle) . -MODE 2 FIG 3<U>Freinage important</U> - 2 feux stop latéraux ( 3 Fig 6 ) allumés en continu . The deceleraton measured at the speedometer (1 Fig 6) will be analyzed by a smart card (2 Fig 6) which has memorized 4 deceleration ranges, each type of deceleration causing a particular ignition of the stop lamps and / or hazard warning lights . -MODE 1 FIG 2 <U> Normal braking </ U>: 3 stop lamps (3 and 4 Fig 6) light up simultaneously and continuously (current mode). -MODE 2 FIG 3 <U> Heavy braking </ U> - 2 side brake lights (3 Fig 6) continuously lit.

-3 feu stop médian 4 Fig 6 ) en allumage intermittent lent. -3 median stop light 4 Fig 6) slow intermittent ignition.

-MODE 3 Fig 4<U>Freinage d'urgence</U> - 2 feux stop latéraux ( 3 Fig 6 ) allumés en continu. -MODE 3 Fig 4 <U> Emergency braking </ U> - 2 side stop lamps (3 Fig 6) lit continuously.

- 3 feu stop médian 4 Fig 6 ) en allumage intermittent rapide. - 3 median stop light 4 Fig 6) in rapid intermittent ignition.

-MODE 4 Fig 5 La décélération est supérieure aux normes données par le constructeur pour le véhicule ( obstacle , accident ). -MODE 4 Fig 5 The deceleration is higher than the norms given by the manufacturer for the vehicle (obstacle, accident).

-3 feux stop ( 3 + 4 Fig 6 ) en allumage continu. - feux de détresse ( 5 fg 6 ) allumage intermittent rapide ( à désactiver manuellement ) . -- <U>Remarque</U> : Le passage d' un mode à un autre se fait en un centième de seconde lors de variation dans le temps de la décélération et passage d'une plage à une autre . -3 brake lights (3 + 4 Fig 6) in continuous ignition. - hazard warning lights (5 fg 6) rapid intermittent ignition (to be deactivated manually). - <U> Note </ U>: Switching from one mode to another is done in one hundredth of a second when there is a change in the deceleration time and change from one track to another.

<U>Applications industrielles</U> : Montage sur tous les véhicules automobiles de l'invention pour prévénir le véhicule suiveur de - l'importance de la décélération du véhicule qui le précède. Eviter au maximum les carambolages .<U> Industrial Applications </ U>: Mounting on all motor vehicles of the invention to prevent the following vehicle from - the importance of the deceleration of the vehicle in front. Avoid as much as possible pileup.
