Claim:
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, wherein if the length and width of the trailer are known, calculating a corrected mirror viewing angle includes identifying two triangles where a first triangle is for when the vehicle is traveling straight and the trailer is not angled relative to the vehicle and the second triangle is for when the vehicle is traveling around a curve and the trailer is angled relative to the vehicle, said first and second triangles both including a first side from the rear-view mirror being corrected to a front-center location of the trailer, a second side from the front-center location of the trailer to a rear corner of the trailer on the side of the trailer that the mirror being corrected is on and a third side from the rear corner of the trailer to the mirror being corrected; and changing the viewing angle of the rear-view mirror using the corrected viewing angle.
