A vehicle guidance system for directing a vehicle along a predetermined path comprises an onboard computer, a number of distance sensors and a steering system controllable by the computer. The predetermined path is stored in a memory of the computer and, in operation, the steering system is controlled to follow the predetermined path. The sensors are adapted to measure the distance, laterally of the vehicle travel direction, between the sensors and curbs provided along the predetermined path, and the computer is adapted to control the steering system to correct any lateral deviation from the predetermined path as detected by the sensors.

Vehicle guidance system

An automated vehicle protection system is provided comprising a guideway (), a vehicle (), a guideway loop antenna (), and transponders (), mounted on the vehicle (). Means () are provided, couple to the guideway loop antenna (), for receiving a signal from the vehicle () and generating an inhibit signal in order to inhibit vehicle movement in a section of the guideway (). The inhibit signal may be passed to a circuit associated with another guideway loop antenna () to control transmission of a signal from this other guideway loop antenna ().
