Patent ID: 8862380

Claim:
A system for alarming a front impact danger coupled with a driver viewing direction, comprising: an imaging device that recognizes a driver viewing direction; a sensing device that senses obstacles existing in directions that a driver does not view; and an engine control unit that receives and analyzes driver face direction data from the imaging device to identify the driver viewing direction when the vehicle enters in crossroads, and that request the sensing device to perform obstacle sensing for a direction opposite to the driver viewing direction and to analyze an obstacle sensing result, wherein when both eyes are detected from the face direction data, the engine control unit forms a right triangle by connecting a nose center to a center point of a left eye center and a right eye center and connecting a point drawing a line perpendicular to a line that connects the left eye center and the right eye center from the center point of the left eye center and the right eye center to the nose center and calculates an angle toward the center point of the left eye center and the right eye center on the right triangle as the both eyes based face direction angle.
