Definitions

  • the automatic system to avoid accidents in motor vehicles due to sleep in the driver referred to in this description, will have its application in the automotive vehicle manufacturing industry, as well as in the spare parts and accessories industry, since It does not require special modifications in the construction of the car but simply special variations in the steering wheel and the insertion of an electrical or electronic circuit suitable for the operation of the system.
  • the automatic system to avoid accidents in motor vehicles due to the effect of sleep on the driver, to which this invention refers, is based on the fact that, when a person begins to fall asleep, the muscles relax, losing the tension and strength that in the normal state are maintained .

  • This same electrical circuit provides that by means of a porizer, after a time not exceeding three seconds, the ignition of the engine and the interruption of fuel entry into the carburetor occurs, while, through appropriate means two, an element that acts on the braking system, with a maximum of three seconds the vehicle is automatically stopped if before the driver has not reacted and taken control of the vehicle, as could happen if it is not drowsiness or sleep, but a collapse due to a heart attack, or any other type of illness that can leave the individual without control over their senses.

  • the first phase of the system is more than enough for the driver to react and take control of the vehicle that has not been lost more than in a few thousandths of a second, since the pressure of the hands is almost instantaneous with the first effects from the sleepiness of the dream; however, the second phase is planned, for cases where the cause is not only sleep, but any other major reason, such as a heart attack, a diabetic coma or any other cause of greater severity

Abstract

Système automatique permettant d'éviter les accidents de véhicules automobiles à cause de l'effet du sommeil sur le conducteur, ce système étant constitué d'un interrupteur périphérique annulaire (4) placé sous la surface inférieure du volant et doté de moyens pour le maintenir dans la position la plus séparée par rapport au volant, l'interrupteur restant ouvert lorsque les mains du conducteur tiennent le volant et, lorsque cette pression manuelle cesse à cause de l'effet du sommeil, il y a séparation de l'interrupteur et donc fermeture du circuit électrique monté à cet effet, ce qui entraîne instantanément l'allumage des feux de détresse (8) et la mise en route d'un équipement sonore (9), un temporisateur (10) étant prévu dans le circuit afin que, si le conducteur ne réagit pas dans un intervalle de temps prédéterminé, une seconde phase est déclenchée entraînant la coupure de l'allumage (11) et de l'alimentation en carburant (12), et une action directe sur les freins du véhicule (14).
