Automobile windshield anti-dazzle device not influencing vision of driver and method of automobile windshield anti-dazzle device

Abstract

The invention discloses an automobile windshield anti-dazzle device not influencing the vision of a driver. The automobile windshield anti-dazzle device not influencing the vision of the driver includes a light intensity detection part, an information processing part and an execution part; the light intensity detection part includes an ambient light intensity detection sensor and a strong light detection sensor, under the condition that a strong light spot and the ambient light in an automobile are detected, the information processing part converts an optical signal into an electrical signal and outputs an instruction to the execution part, so the light transmission of the corresponding position on a windshield is decreased and a region is dimmed, and the light intensity captured by eyes of the driver is weakened. According to the automobile windshield anti-dazzle device, the structure is simple, the occupied space is not large, and the vision and driving comfort of the driver are notaffected; from the perspective of self-protection of the driver, aiming at vision conditions of the driver and environment in the automobile, the light intensity is adjusted; and a variable-color windshield is adopted, by decreasing the light transmission of the corresponding position, dazzle produced by the driver when the driver drives at night is well avoided, and the automobile windshield anti-dazzle device is suitable for all types of vehicles and has high promotion.

Description

technical field [0001] The invention belongs to the technical field of automobiles and optics, and in particular relates to an anti-glare device and method for an automobile windshield that does not affect the driver's field of vision. Background technique [0002] There are two main reasons for the dazzling feeling: one is that the light intensity in a certain part of the space domain is relatively strong, which is much stronger than the ambient light. Human pupils have adapted to the ambient light in this background, so it will cause Discomfort, the specific manifestation is the dazzling situation between cars at night; the second is that the overall ambient light has exceeded the threshold that the human pupil can bear, and the specific manifestation is that the sunlight is too strong during the day. [0003] During the driving process of the car, especially at night, the driver is easily disturbed by the lights of other vehicles, especially when two cars are driving in t...

Problems solved by technology

[0003] During the driving process of the car, especially at night, the driver is easily disturbed by the lights of other vehicles, especially when two cars are driving in the opposite direction, even the low beam will cause trouble to the driver. It will affect the driving experience, and even cause traffic accidents

In response to this situation, the currently available technologies include active and passive technologies. The active technology is mainly the automatic adjustment technology of car lights, that is, when the car lights sense the car coming ahead, it will automatically reduce the lighting range, thereby reducing the impact on other cars. This technology is mainly from the perspective of considering other cars, and has no protective effect on itself, and not all vehicles are popularized with this technology, so its shortcomings are also obvious; passive technology mainly includes anti-glare light barriers and smart LCDs Color-changing light baffle, the main installation position of this kind of light baffle is stuck on the original light shading plate, this kind of light baffle effectively makes up for the shortcomings of active technology, and can prevent glare by itself, but due to its installation position, it will appear The driving space is too tight, which affects the comfort and may affect the driver's vision. The degree of weakening the light intensity of the general light barrier is certain, and the light intensity received by the human eyes changes when the car is driving at night, so it cannot It completes the task very well, because the light received at night is mainly a point in the space domain that is particularly strong and irradiates the eyes. The smart liquid crystal color-changing light shield is dimmed in its entirety. If a point of light is particularly strong, it may make the Other parts are not imaged, seriously affecting driving safety
