ABSTRACT:
A vehicle guidance control system is described for an operatorless vehicle comprising a sensor for determining the presence of defined points along a selected path that the vehicle is to travel, a memory having a plurality of locations, each location for receiving one of a set of commands whereby the vehicle may be commanded to turn, pause, or to continue its movement. An address circuit is responsive to the detection of a point for addressing the corresponding location within the memory means, whereby command stored therein is executed to effect vehicle control. The vehicle guidance control system is adapted to guide the vehicle along a selected path within a set of corridors as would be found in a mine, wherein the corridors are disposed respectively along X and Y directions to form thereby a series of intersection points. The sensor means is disposed upon at least one side of the vehicle to sense the presence of an intersecting corridor, the address circuit accesses the location of the memory circuit corresponding to the detected point of intersection of the mine corridors to access the vehicle command stored at that location. The control guidance system includes a second location within the memory circuit for retaining the location of the vehicle in terms of its X,Y coordinate position within the grid of corridors, the output of the sensor serving to update the stored current vehicle position. Upon reaching an intersection of corridors, the second memory location is also updated as to the current location of the vehicle.
