Abstract

Le problème décrit par la présente invention est de notifier à un administrateur des incidents en tenant compte de l'état physique d'un conducteur pendant la conduite. À cet effet, l'acquisition d'informations biologiques concerne le conducteur pendant la conduite (étape S1). Les informations biologiques sont analysées, une condition physique est détectée, un premier incident est évalué comme ayant eu lieu si la condition physique détectée satisfait des conditions prescrites, et des informations de fonctionnement concernant le conducteur sont acquises (étape S2). Les informations de fonctionnement sont analysées, une opération est détectée, un second incident est évalué comme ayant eu lieu si l'opération détectée satisfait des conditions prescrites, et des informations de comportement se rapportant à un véhicule sont acquises (étape S3). Les informations de comportement sont analysées, le comportement est détecté, le comportement détecté est collationné avec un système de reconnaissance des panneaux de signalisation, et un troisième incident est évalué comme ayant eu lieu si le comportement trouvé ne doit pas être en conformité légale. Si la combinaison de ces incidents satisfait des conditions prescrites, il est déterminé qu'un grave incident s'est produit, et l'administrateur est informé d'informations relatives à l'incident grave.
