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 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.

[ What is claimed is:] [1.] A method for detecting a target obstacle in front of a vehicle traveling on a road, the vehicle having a radar positioned at a center of the vehicle for transmitting radar waves ahead of the vehicle, the method comprising:determining a first position of at least one object in front of the vehicle relative to the radar based on the radar waves;determining a tangent of the lane boundary of the road; determining a line intersecting the tangent perpendicularly through the center of the vehicle and the lane boundary so as to define a point corresponding to a first lateral deviation between the center of the vehicle and a lane boundary of the road;determining a curvature of the road based on the first lateral deviation;determining a second position of the at least one object relative to the radar and the road based on the curvature of the road; anddetermining the target obstacle based on the second position of the at least one object.
