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. |
