A multi-point serial link protocol, such as USB, is used to transfer vehicle diagnostic information back and forth between vehicle diagnostic sensors and a host computer. Multiple distinct vehicle servicing applications may be added to or removed from the service bay without requiring substantial software changes or revisions. The amount of vehicle diagnostic hardware is also minimized. The multi-point serial link may originate in the vehicle's on-board computer, allowing the vehicle itself to function as a data hub for the diagnostic automotive service sensors.

La présente invention concerne un protocole à liaison série multipoints, tel que celui de bus série universel (USB), destiné à transférer, en aller et retour, une information de diagnostic de véhicule entre des capteurs de diagnostic de véhicule et un ordinateur central. Des applications multiples, distinctes, de maintenance de véhicule peuvent être ajoutées ou éliminées de la station de travail sans nécessité de changement ou de révision de logiciel. La quantité d'équipement de diagnostic de véhicule est aussi minimisée. La liaison série multipoints peut être installée au départ dans l'ordinateur embarqué du véhicule, ce qui permet au véhicule, lui-même, de fonctionner comme un groupeur de données provenant des capteurs de diagnostic de maintenance de véhicule.
