Abstract
A navigation system for navigating an autonomous vehicle along a path that is confined by walls that are within range of on-board sensors is described. The system determines the relative location and orientation of the walls with respect to the vehicle. The system controls the steering angle and the ground speed of the vehicle by employing: (a) range data to establish free space in front of vehicle; (b) active contours to generate a desired path; (c) driving hints to guide the active contours along arcs and open areas; (d) steering hints to confine the active contours to a specific domain of free space, at, for instance, intersections; and (e) a desired path to generate steering demand or velocity.
