Abstract
An external-world recognition system includes: a satellite positioning device that measures the position of a vehicle by receiving radio waves transmitted from artificial satellites; a yaw rate sensor that detects or estimates the movement of the vehicle; a camera that acquires external-world information about the surroundings of the vehicle; and an external-world recognition device that recognizes external-world information considering a reference direction as the center. The external-world recognition device corrects a detection value from the yaw rate sensor on the basis of time-series positions of the vehicle as measured by the satellite positioning device and corrects the reference direction on the basis of the corrected detection value.
