L'unité d'interface de véhicule (22) reçoit des signaux provenant du véhicule par l'intermédiaire du connecteur d'interface (24) avec le véhicule, tels que des signaux relatifs à la distance parcourue et à d'autres caractéristiques de fonctionnement, par exemple le fonctionnement des phares, les clignotants, les freins ou les ceintures de sécurité, et ces signaux sont communiqués par l'intermédiaire d'une liaison de communication à l'unité enregistreuse de données (20). L'unité (20) comprend une mémoire (250) dans laquelle de telles informations sont mémorisées, et l'unité enregistreuse de données (20) peut être déconnectée de l'unité d'interface (22) du véhicule et interconnectée à un dispositif externe tel qu'un ordinateur (100) ou une imprimante (102) pour sortir des informations stockées dans la mémoire (250). L'unité d'enregistrement des données (20) peut également être utilisée pour stocker d'autres informations concernant par exemple des dépenses professionnelles commerciales ou autres. L'unité d'enregistrement de données (20) permet à un opérateur de savoir si les kilomètres parcourus par le véhicule sont pour une utilisation professionnelle ou personnelle, ceci permettant à l'opérateur de suivre de près l'utilisation du véhicule pour des raisons professionnelles ou pour des raisons personnelles, ainsi que d'autres dépenses encourues par l'opérateur. Des informations stockées dans l'unité d'enregistrement de données (20) peuvent être imprimées à l'aide d'une imprimante (102) ou téléchargées dans un ordinateur (100) pour fournir ensuite un rapport imprimé.
