Road curvature estimation for rearview mirror adjustment system
First Claim
1. A method for correcting a viewing angle of a rear-view mirror on a vehicle when the vehicle is traveling around a curve, said method comprising:
- determining the curvature of the road using only a speed of the vehicle and a steering angle of the vehicle;
calculating a corrected mirror viewing angle based on the curvature of the road; and
changing the viewing angle of the rear-view mirror using the corrected viewing angle.

Abstract
A system and method for automatically correcting the viewing angle of a rear-view mirror on a vehicle when the vehicle is traveling around a curve. The system estimates the curvature of the road using only vehicle speed and vehicle steering angle information. The road curvature estimation is used to determine the radius of curvature of the road, which can then be used to determine the corrected viewing angle of the rear-view mirror. Depending on whether the road is curving to the right or to the left will determine whether the left side rear-view mirror or the right side rear-view mirror will be adjusted.
