Abstract
A method and system for detecting a target obstacle in front of a vehicle traveling on a road includes a radar positioned at a center of the vehicle for transmitting radar waves ahead of the vehicle for use in determining a first position of the objects in front of the vehicle relative to the radar. A lane position measurement device determines a lateral deviation between the center of the vehicle and a lane boundary of the road. Control logic then determines a curvature of the road based on the lateral deviation, independent of the traveling path of the vehicle. The control logic then determines a second position of the objects based on the curvature of the road and the target obstacle based on the second position of the objects.
