ABSTRACT:
A vehicle running guidance system using magnetic markers for the purpose of reducing the number of magnetic markers to be laid on a road surface. The magnetic nails are laid as magnetic markers on a road. The radio wave generator tags are also laid. The radio wave generator tags transmit road curve data for a distance of about 100 m in the running direction. Power for the radio wave generator tags is supplied from a magnetic generator on a vehicle. On the vehicle, the relative displacement from a magnetic nail is detected by a magnetic sensor, and at the same time the road curve data from radio wave generator tags is received by a radio wave receiving device. The controller determines the amount of steering, based on relative displacement with respect to magnetic nails and road curve data, and supplies it to the actuator. Transmission of road curve data contributes to reducing the number of magnetic nails.
