Abstract: The present invention provides a steering risk decision system and method that determine and provide a steering risk of a vehicle to a driver. The system includes an obstacle sensor that senses an obstacle to generate first sensor data and a driving state sensor senses a driving state of a vehicle to generate second sensor data. In addition, a processor extracts feature points from first sensor data to indicate the obstacle in point and line shapes and predicts a driving region of the vehicle using second sensor data. Further, the processor calculates a relationship between the vehicle and the obstacle using information for the obstacle indicated in the point and line shapes and information for the driving region to determine a steering risk of the vehicle based on the calculated result.

Abstract: 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.
