Method and apparatus for correcting a curve radius
First Claim
1. A method for correcting the curve radius of the lane on which the vehicle is traveling, the method comprising:
- detecting the curve radius by a curve detection sensor;
determining whether the curve radius is wrong based on the first detected position and the present position of a leading vehicle;
computing a virtual curve radius based on the detected information about the leading vehicle; and
synthesizing the horizontal relative position for the curve radius and the horizontal relative position for the virtual curve radius.

Abstract
The present invention relates to traveling control for a vehicle and, in particular, to a method and apparatus, in an adaptive cruise control (ACC) system for a vehicle, for correcting the curve radius of the lane on which the vehicle is traveling, wherein the curve radius is corrected accurately and speedily based on the information about the movement of a leading vehicle detected with a radar, etc. The apparatus, in the ACC system, for correcting the curve radius comprises a means of computing a virtual curve radius based on the information about the horizontal movement of the leading vehicle, a means of computing the horizontal relative position for the curve radius obtained by the ACC system and the horizontal relative position for the virtual curve radius, and a means for correcting the curve radius based on the value obtained by synthesizing the computed horizontal relative positions.
