More Information
Summary:An external environment recognizing device for vehicle includes an image acquiring unit configured to acquire image obtained by picking up image of an area ahead of an own vehicle, a light-source extracting unit configured to extract light source from the acquired image, an own-vehicle-speed acquiring unit configured to acquire own vehicle speed, an oncoming-vehicle-presence-possible-region estimating unit configured to estimate oncoming vehicle presence possible region on the basis of own vehicle speed, and an oncoming-vehicle detecting unit configured to detect an oncoming vehicle on the basis of the oncoming vehicle presence possible region and the light source. The oncoming-vehicle-presence-possible-region estimating unit estimates oncoming vehicle presence possible region on the basis of the own vehicle speed, a minimum curvature radius of traveling road corresponding to a speed limit determined in advance, and traffic information indicating whether driving on the traveling road is driving on the right side or the left side.
