System and method for alarming front impact danger coupled with driver viewing direction and vehicle using the same

A method for alarming a front impact danger coupled with a driver viewing direction, comprising:

• receiving, by an engine control unit, crossroads information and moving direction information of a vehicle when the vehicle enters in crossroads;
• checking, by the engine control unit, the driver viewing direction;
• sensing, by the engine control unit, obstacles existing in another direction that the driver does not view using a sensing device;
• and
• checking, by the engine control unit, if the vehicle enters in the moving direction of the vehicle according to presence of the obstacle as the sensing result of the obstacle,
• wherein when both eyes are detected from the face direction data, the checking the driver viewing direction includes:
• forming 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
• calculating 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.

A vehicle using 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 requests obstacle sensing for a direction opposite to the driver viewing direction to the sensing device 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 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.
