Improve fuel economy method using Road gradient extraction by driving front image

摘要

The present invention relates to a method for extracting road slope and improving fuel economy through a vehicle driving image, and more particularly, in a method for extracting road slope and improving fuel efficiency when driving a vehicle, wherein image information is obtained by using an imaging device mounted on the vehicle. The first step of collecting, the second step of setting the horizontal reference line of the vehicle in a horizontal section based on the image information, a telephone pole on the left or right side of the road to determine the slope based on the image information, the state of the preceding vehicle, and In the third step of determining any one or more reference objects among the width of the shadow or the width of the driving road and extracting the reference object, the fourth step of determining the slope of the road using the reference object of the third step, and the fourth step By inducing/controlling the ECU for inertial driving by analyzing the curvature of the driving front road in real time, consisting of technical features including the fifth step of controlling the electronic control unit (ECU) of the vehicle according to the calculated slope. There is an effect of increasing the fuel economy of the vehicle.
