ABSTRACT:
A traveling device for calculating the relative displacement of a vehicle in a road using a magnetic sensor and a CCD camera and performing automatic steering. The vehicle is equipped with a magnetic sensor and a CCD camera. A magnetic ECU processes a signal from the magnetic sensor, an image ECU processes a signal from the CCD camera and the resulting relative displacements are both output to a vehicle control computer. When a relative displacement output from the image ECU is not irregular, the vehicle control computer performs steering control after calculating an amount of corrective steering using this relative displacement and, when it is irregular, the vehicle control computer performs steering control after calculating an amount of corrective steering using the relative displacement output from the image ECU.
