CA 2684327

A vehicle guidance system for directing a vehicle (10) along a predetermined path comprises an onboard computer (26), a number of distance sensors (18, 20, 22, 24), and a steering system (16) controllable by the computer. The predetermined path is stored in a memory (28) of the computer (26) and, in operation, the steering system is controlled to follow the predetermined path. The sensors (18, 20, 22, 24) are adapted to measure the distance, laterally of the vehicle travel direction A, between the sensors and kerbs (30, 32) provided along the predetermined path, and the computer (27) is adapted to control the steering system (16) to correct any lateral deviation from the predetermined path as detected by the sensors.

L'invention concerne un système de guidage de véhicule pour diriger un véhicule (10) le long d'un trajet prédéterminé, qui comprend un ordinateur embarqué (26), un certain nombre de capteurs de distance (18, 20, 22, 24) et un système de direction (16) pouvant être commandé par l'ordinateur. Le trajet prédéterminé est stocké dans une mémoire (28) de l'ordinateur (26) et, en fonctionnement, le système de direction est commandé pour suivre le trajet prédéterminé. Les capteurs (18, 20, 22, 24) sont conçus pour mesurer la distance, latéralement à la direction de déplacement de véhicule A, entre les capteurs et les bords de trottoir (30, 32) disposés le long du trajet prédéterminé, et l'ordinateur (27) est conçu pour commander le système de direction (16) pour corriger tout écart latéral par rapport au trajet prédéterminé tel que détecté par les capteurs.
