ABSTRACT:
An optical system for aiding the driver of a vehicle in judging the proximity of the forward end of the vehicle to an object directly in front of the vehicle, particularly when parking close to a wall or barricade or when pulling up close to another vehicle stopped at an intersection. An illuminated target and a mirror mounted beneath opposite sides of the dashboard are used to reflect an image of the target off the interior surface of the windshield at a location so that the reflected image is in the normal field of view of the driver. A virtual image of the target is perceived by the driver to emanate from a position above the forward end of the vehicle. The driver may gradually advance the vehicle until the virtual image appears to the driver to be juxtaposed with the object at which time there will be a predetermined minimum safe distance between the forward end of the vehicle and the target.
