ABSTRACT:
A road for guiding an automatically driven vehicle comprises a train of N-polarity magnetic nails arranged along a main path, and a train of S-polarity magnetic nails arranged on a branching path. An automatically driven motor vehicle, including magnetic sensors, runs and is automatically steered by detecting the magnetic nails. The vehicle can be precisely controlled to follow a desired running direction by detecting the presence of magnetic nails with the magnetic sensors. More specifically, at an upstream side of a branch point, when the desired direction is along a main path direction, a driving (steering control) mode of the vehicle is selected in which the magnetic sensors detect N-polarity magnetic nails. Similarly, when the desired direction of travel is along a path which branches off from the main path, a driving (steering control) mode is selected in which the magnetic sensors detect S-polarity magnetic nails. In this manner, the motor vehicle can be automatically driven even at branch points in the road, and wherein the branch points also comprise magnetic nails installed therein at predetermined intervals.
