Autonomous vehicle guidance system

摘要

A system guides self-propelled equipment through passageways, such as underground mine corridors. The vehicle contains a signal generator for bouncing signals off the walls of the passageways. A receiver collects the signals bounced off of the passageways to determine the distance to side walls of the passageways. A storage device contains a set of interlinking nodes that represent at least one path through the passageways. Each of the nodes contains steering information. A processor finds the distance to the side walls of the passageways in order to steer the vehicle through the passageways. The system's operational state and method of steering changes depending upon the location of the equipment in the interlinking nodes.
