  • Integrated vehicle positioning and navigation system, apparatus and method
    Patent number: 5610815
    Abstract: A system (400) for positioning and navigating an autonomous vehicle (310) allows the vehicle (310) to travel between locations. Position information (432) is derived from global positioning system satellites (200, 202, 204, and 206) or other sources (624) when the satellites (200, 202, 204, and 206) are not in the view of the vehicle (310). Navigation of the vehicle (310) is obtained using the position information (432), route information (414), obstacle detection and avoidance data (416), and on board vehicle data (908 and 910).

  • System and method for managing access to a resource in an autonomous vehicle system
    Patent number: 5586030
    Abstract: The invention is a system and method for managing a resource shared by a plurality of autonomous vehicles. Each vehicle includes a navigator for causing the vehicle to travel a specified route to the resource and for generating a queue position request upon approach to the resource. A queue or fleet manager establishes a queue to control access to the resource. The queue manager generates a queue position in response to receipt of the queue position request from an approaching vehicle. Under control of the queue manager, autonomous vehicles are passed through the queue and allowed to access the resource in a first-in, first-out manner.

  • Multi-tasked navigation system and method for an autonomous land based vehicle
    Patent number: 5548516
    Abstract: A system (400) for positioning and navigating an autonomous vehicle (310) allows the vehicle (310) to travel between locations. Position information (432) is derived from global positioning system satellites (200, 202, 204, and 206) or other sources (624) when the satellites (200, 202, 204, and 206) are not in the view of the vehicle (310).
