Le dispositif d'entrée (6) est conçu pour effectuer l'entrée interactive de l'ensemble ou des ensembles de données réelles générées par le conducteur. Une unité de traitement (5) est en outre prévue pour réaliser une comparaison théorique-réel entre l'ensemble ou les ensembles de données théoriques et l'ensemble ou les ensembles de données réelles générées par le conducteur lors d'un signal de modification. Lorsque la comparaison théorique-réel est positive, il se produit une modification pour passer du premier système d'exploitation au deuxième système d'exploitation. Cette invention concerne en outre un véhicule, un procédé pour faire fonctionner le système d'aide à la conduite, un programme informatique et un support d'enregistrement lisible par ordinateur.
