Vision enhancement device for use in vehicle
First Claim
1. A vision enhancement device for use in a vehicle, comprising:
- dividing means for making a projection substantially horizontally on a surface of a windshield of the vehicle and thereby dividing the windshield into a plurality of areas, the dividing means being formed such that when the projection is made onto the windshield so as to correspond to a position of a road surface that is a predetermined distance ahead with a vantage point position of an operator used as a starting point, a projection width on the windshield is the same as or smaller than a lane width of the road,wherein the dividing means comprise false image generating means disposed beneath the windshield for showing a false image on the windshield, and first light emitting means for emitting light for at least a portion of the dividing means, the false image generating means being configured so as to form a rectilinear false image that can be recognized in a substantially rectilinear manner from the vantage point position of the operator, the first light emitting means being designed to emit light more brightly in one portion of the rectilinear false image than in another portion.

Abstract
A vision enhancement device for use in a vehicle that improves the frontward vision of an operator during operation. The device has two dividing lines set apart from each other on an instrument panel. These dividing lines show as false image lines on an inside surface of a front window, and divide the inside surface of the front window into a plurality of areas in a vertical direction. A second area formed between these two false image lines forms an appropriate visual field range when the operator looks forward while operating the vehicle. First light emitting means comprising light emitting diodes are disposed at both ends of each of the two dividing lines. The light emitted by these light emitting diodes is directed onto the front window as a false image in accordance with changes in the vehicle state and the environment around the vehicle.

7. A vision enhancement device for use in a vehicle, comprising:
-
dividing means for making a projection substantially horizontally on a surface of a windshield of a vehicle and thereby dividing the windshield into a plurality of areas, the dividing means being formed so that when the projection is made onto the windshield so as to correspond to a position of a road surface that is a predetermined distance ahead with a vantage point position of an operator used as a starting point, a projection width on the windshield is the same as or smaller than a lane width of the road, wherein the dividing means is disposed beneath the windshield for showing a false image on the windshield, the false image being substantially rectilinear as seen from the vantage point position of the operator and having at least a first section having a first color and a second section having a second color different from the first color, and wherein the dividing means communicates with at least one vehicle sensor and changes a color of one of the first and second sections in response to a predetermined output of the vehicle sensor. - View Dependent Claims (8, 9)
