ABSTRACT:
A motor vehicle is automatically steered to run along a running path on a road while detecting magnetic nails that are arranged on the road at spaced intervals along the running path. The motor vehicle has a pair of magnetic nail sensors on respective front and rear portions thereof for detecting lateral deviations of magnetic nails with respect to the motor vehicle at the respective front and rear portions thereof. The magnetic nail sensors are spaced from each other by a distance which is substantially an integral multiple of the interval between adjacent two of the magnetic nails. An azimuth deviation or a lateral deviation of the motor vehicle with respect to the running path is calculated based on lateral deviations of the magnetic nails which are detected substantially simultaneously by the magnetic nail sensors, respectively.
