Abstract
A vehicle control system having a controller and a spatial database adapted to provide spatial data to the controller at control speed. The spatial data provided from the spatial database to the controller includes images collected from an optical sensor subsystem in addition to other data collected by a variety of sensor types, including a GNSS or inertial measurement system. The spatial data received by the controller from the database forms at least part of the control inputs that the controller operates on to control the vehicle. The advantage provided by the present invention allows control system to “think” directly in terms of spatial location. A vehicle control system in accordance with one particular embodiment of the invention comprises a task path generator, a spatial database, at least one external spatial data receiver, a vehicle attitude compensation module, a position error generator, a controller, and actuators to control the vehicle.
