Activation control of a vehicular rear view video display
First Claim
1. A rear view display control for a vehicle, comprising the steps of:
- providing a video display for a driver of the vehicle;
providing an imaging device for producing video image signals responsive to an in-path portion of a scene rearward of the vehicle;
activating said video display with the produced video image signals to display a video image of the in-path portion of said rearward scene when said vehicle is being operated in reverse; and
deactivating said video display when a speed of said vehicle during reverse operation exceeds a reference speed to encourage the driver to consider both in-path and out-of-path portions of said rearward scene when the reverse speed of the vehicle exceeds said reference speed.

Abstract
The activation of a rear view video display in a vehicle is interrupted under specified operating conditions to discourage inappropriate driver reliance on the video display. The video display is automatically activated when the reverse transmission range of the vehicle is selected, but is deactivated if the vehicle speed in the reverse range exceeds a calibrated threshold such as 2-3 MPH. When the vehicle speed falls back below the threshold, the video display is automatically re-activated, thereby encouraging the driver to use the video display only for the purposes for which it was designed, and to use other ways of obtaining a more comprehensive rearward view when backing at speeds in excess of the threshold.
