Patent number: 9278695Abstract: A method for detecting a narrow road includes calculating relative heights of points from a distance measuring sensor to a ground based on distance information. A left boundary point and a right boundary point, at which a difference in relative heights from adjacent points becomes maximal, are acquired. A road boundary line of a driving road is acquired based on the left boundary point and the right boundary point depending on a movement trajectory of the vehicle when a difference in relative heights at the left boundary point and the right boundary point is more than or equal to a reference value. A road width of the driving road is calculated based on the road boundary line. It is detected whether the driving road of the vehicle is a narrow road based on the road width.Type: GrantFiled: October 20, 2014Date of Patent: March 8, 2016Assignee: HYUNDAI MOTOR COMPANYInventors: Ki Cheol Shin, Chang Jae Lee, Ee Suk Jung
