Le procédé consiste à : déterminer un quatrième degré de fatigue d'un conducteur en fonction des quatrièmes informations physiologiques obtenues du conducteur ; lorsqu'il est déterminé que le quatrième degré de fatigue ne satisfait pas à une exigence de conduite sûre, il convient de commander un quatrième dispositif de liaison dans un véhicule et/ou de commander le véhicule de manière à le déplacer selon le quatrième degré de fatigue, le quatrième dispositif de liaison étant utilisé pour ajuster l'environnement à l'intérieur du véhicule et/ou empêcher le véhicule de se déplacer ; et lorsqu'il est détecté que le conducteur est dans un état fatigué, la fatigue pouvant être soulagée au moyen d'un dispositif de liaison embarqué, il convient d'interdire temporairement la conduite du véhicule, ce qui permet d'assurer la sécurité de conduite. En outre, le mode de réalisation de la présente invention concerne un dispositif et un système de commande de véhicule, et un support d'enregistrement lisible par ordinateur.
