Abstract
An external environment recognition deviceestimates a blind spot region around a host vehicle based on information detected by a sensor that detects a target around the host vehicle. The external environment recognition deviceincludes a visibility index determination unitthat calculates a visibility index of the target based on a coordinate point and a reflection intensity of the target detected by the sensor, and assigns the visibility index to a region from the host vehicleto the coordinate point of the target, a visibility map storage unitthat stores the visibility index as a visibility map in association with the region, and a blind spot region estimation unitthat estimates the blind spot region based on the visibility map.
