Abstract

L'invention concerne les moyens permettant d'assurer l'orientation de véhicules sur la chaussée. Le résultat technique de l'invention consiste à réduire la consommation de main d'oeuvre de montage des sources de champ magnétique. L'invention est mise en œuvre de la façon suivante. On applique à la surface de la route (12) au moyen d'un matériau marquant un marquage routier (2) qui se présente comme de différents segments, écriteaux, indicateurs de direction sous forme de couches (8). On introduit dans le matériau des couches (8) des substances à propriétés magnétiques et une aimantation résiduelle, qui se présentent dans le cas d'espèce comme des ferromagnétiques en poudre à aimants solides. Grâce à une force de cohésion importante et une aimantation résiduelle relativement élevée, les ferromagnétiques à aimants solides peuvent garder de champs magnétiques forts pendant une durée relativement élevée. Lors du déplacement de l'automobile (4) sur la chaussée les capteurs de champ magnétique (premier capteur de champ magnétique (1), deuxième capteur de champ magnétique (2), troisième capteur de champ magnétique (6), quatrième capteur de champ magnétique (7)), on forme un signal qui dépend de l'intensité du champ magnétique du marquage routier.
