First Claim
1. A method of using a rear vision system for a host vehicle, the rear vision system includes a rear facing camera, a vehicle-to-vehicle (V2V) unit, and an electronic display mirror, and the method comprises the steps of:
- determining if a towed object behind the host vehicle is obstructing the rear facing camera;
identifying an area of interest behind the host vehicle when the rear facing camera is obstructed;
gathering information from a remote vehicle with the V2V unit;
using the gathered information to determine if the remote vehicle is in the area of interest;
generating a rendering of the remote vehicle when the remote vehicle is in the area of interest; and
displaying the video output and the rendering of the remote vehicle on the electronic display mirror in the form of enhanced video output.

Abstract
A rear vision system and a corresponding method for use with a host vehicle towing a trailer or other object. The rear vision system may include a rear facing camera, a vehicle-to-vehicle (V2V) unit, vehicle dynamic sensors, a navigation unit, a control unit, and an electronic display mirror. When the towed trailer obstructs the rear facing camera, the system and method look for unseen vehicles behind the trailer and use the V2V unit to gather information from these vehicles. This information is then used to generate a rendering that graphically depicts or represents the unseen vehicle, and the rendering is superimposed on top of the video output from the rear facing camera in the form of enhanced video output, which is then displayed on the electronic display mirror. Thus, the driver is able to “see” behind the obstructing trailer without the use of additional cameras installed on the trailer.

18. A rear vision system for use with a host vehicle, comprising:
-
a rear vision system control unit; a rear facing camera that is coupled to the control unit and provides the control unit with video output of an area behind the host vehicle; a vehicle-to-vehicle (V2V) unit that is coupled to the control unit and provides the control unit with traffic output relating to one or more remote vehicles; and an electronic display mirror that is coupled to the control unit and receives enhanced video output from the control unit; wherein the control unit is configured to use the traffic output from the V2V unit to generate a rendering of an obstructed vehicle, to add the rendering of the obstructed vehicle to the video output from the rear facing camera so as to create the enhanced video output, and to provide the enhanced video output to the electronic display mirror.
