Title:
METHOD FOR DETERMINING A RELATIVE GRADIENT OF A ROADWAY
Document Type and Number:
WIPO Patent Application WO/2015/052158
Kind Code:
A3
Abstract:
The invention relates to a method for determining the gradient of a roadway located at a distance in front of a motor vehicle relative to the roadway section being travelled over by the motor vehicle, wherein images of the roadway located in the front of the motor vehicle are recorded by a camera, route lines in front of the motor vehicle are detected in the recorded images and the relative gradient is calculated on the basis of differences in the direction of the route lines at different distances. According to the invention, the route lines are in each case interpolated in their entirety in a non-linear manner with respect to a horizon (20') of the roadway located at a distance in front of the motor vehicle, wherein the distance between the thus obtained horizon (20') of the route line and a horizon of the roadway section (20) being travelled is calculated, and wherein the relative gradient is calculated on the basis of the distance (D) between the two horizons (20, 20').
