Abstract

L'invention concerne un appareil d'obtention d'informations (100) qui acquiert des informations comportementales concernant le comportement d'un objet mobile par le biais d'une section d'acquisition (101). Puis, une section d'évaluation (102) évalue l'état de conduite de l'objet mobile, sur la base des informations comportementales acquises par la section d'acquisition (101) et, par exemple, des informations de carte stockées précédemment. Une section d'enregistrement (103) accumule et enregistre des résultats d'évaluation de la section d'évaluation (102). Une section de sortie (104) émet les informations (information de sécurité de conduite) concernant la sécurité de conduite objective de l'objet mobile, sur la base des résultats d'évaluation de la section d'évaluation (102) et des résultats d'évaluation enregistrés par la section d'enregistrement (103).
