Photosensitive protective windshield color changing system

Abstract

The invention provides a photosensitive protective windshield color changing system, which is suitable for a windshield divided into a plurality of blocks, and comprises a light sensing unit used for obtaining a light source position and an ambient luminosity value; the eyeball tracking unit is used for tracking and obtaining an eyeball position of the driver; the vehicle-mounted processing unit is electrically connected with the light sensing unit and the eyeball tracking unit, and generates a windshield block brightness operation instruction according to the light source position, the environment luminosity value and the eyeball position; and the windshield control unit is electrically connected with the windshield and the vehicle-mounted processing unit, and the windshield control unit controls the brightness of each block on the windshield according to the windshield block brightness operation instruction.

Description

technical field [0001] The present invention relates to a photosensitive protection windshield discoloration system which can make the windshield discolor in blocks according to the ambient light, the opposite light source or the illuminating light source. Background technique [0002] At present, the cars on the market do not have light source induction color-changing windshields, and they can only choose to paste heat insulation paper for heat insulation. The sunshade cannot be installed on the front windshield of the car when driving, that is, it cannot be used when driving, and it cannot block the light source outside the car for the driver (such as the lights, sunlight or street lights projected by other vehicles), because It will cause the driver to produce glare, which will affect the vision, especially in the case of strong light reflection during high-speed driving, which is more likely to cause driving danger. [0003] Furthermore, sunshade or heat insulation devi...

Problems solved by technology

[0002] At present, the cars on the market do not have light source sensor color-changing windshield settings, so they can only choose to paste heat insulation paper for heat insulation, which cannot provide suitable and diverse heat insulation effects, sunshade or heat insulation device structures, such as The sunshade cannot be installed on the front windshield of the car when driving, that is, it cannot be used when driving, and it cannot block the light source outside the car for the driver (such as the lights projected by other vehicles, sunlight or street lamps, etc.), because It will cause glare to the driver, which will affect the vision, especially in the case of strong light reflection during high-speed driving, it is more likely to cause driving hazards

[0003] Furthermore, the structure of the sunshade or heat insulation device, such as the sun visor, is easy to block the driver's line of sight when driving, and the driver must be distracted to adjust the line of sight to observe the road conditions and oncoming vehicles, and the adjustable range of its size and position is limited. Covering the height of the driver's line of sight will cause the danger of blind driving, that is, only part of the light source outside the car can be blocked for the driver when driving, which may distract the driver or block the driver's line of sight, thus affecting vision and easily cause driving hazard

[0004] The thermal insulation paper in the known technology is coated or colored thermal insulation paper, which cannot be changed because it only has a fixed lightness and darkness. Therefore, when the color of the thermal insulation paper is too dark, the glass is too dark to affect the line of sight, thereby endangering driving safety; , if the heat insulation paper is not dark enough, it cannot block the light; therefore, under the limited capacity, the heat insulation paper cannot provide the driver with a controllable sunshade or block the strong light of the oncoming car
