REARVIEW MIRROR ADJUSTMENT SYSTEM FOR TRAILER ATTACHED VEHICLE
First Claim
1. A method for correcting a viewing angle of a rear-view mirror on a vehicle that is towing a trailer when the vehicle is traveling around a curve, said method comprising:
- identifying a hitch angle between the vehicle and the trailer;
calculating a corrected mirror viewing angle using the hitch angle; 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 towing a trailer when the vehicle is traveling around a curve. If the dimensions of the trailer are unknown, then the corrected viewing angle is the same as the hitch angle between the vehicle and the trailer. If the dimensions of the trailer are known, then trigonometry is used to determine the corrected viewing angle. 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 is adjusted.
