Abstract

La présente demande divulgue un procédé et un dispositif de rappel de conduite, le procédé consistant à : acquérir, par un dispositif électronique, des informations de conduite d'un premier véhicule, les informations de conduite comprenant un état de regard, la vitesse de conduite du premier véhicule et la vitesse de conduite et la position relative d'un second véhicule ; déterminer, par le dispositif électronique, si les informations de conduite du premier véhicule sont conformes ou non à une condition dangereuse prédéfinie, la condition dangereuse prédéfinie étant utilisée pour indiquer si le premier véhicule est dans un état dangereux ou non ; et si les informations de conduite du premier véhicule satisfont la condition de danger prédéfinie, fournir en sortie, par le dispositif électronique, des informations d'avertissement. Le procédé de rappel de conduite prévu dans la présente demande tient compte non seulement de la situation d'un conducteur regardant un dispositif électronique, mais également de l'association entre le premier véhicule dans lequel se trouve le conducteur et le second véhicule, de façon à analyser les dangers qui peuvent survenir entre le premier véhicule dans lequel se trouve le conducteur et le second véhicule. Par conséquent, des informations d'invite de conduite sûre appropriées sont données sur la base de la situation entre le premier véhicule et le second véhicule, ce qui peut réduire la possibilité pour le conducteur d'avoir un accident de la circulation.
