Embodiment 1

[0072] Please refer to figure 1 , the present embodiment proposes a sunshade method, comprising the steps of:

[0073] S1, acquiring illumination information and eye position information of persons in the vehicle. During specific implementation, the acquired illumination information includes illumination intensity and illumination angle. Specifically, the illumination angle can be judged by image recognition, or the illumination angle can be obtained by arranging multiple point sensors, and the illumination intensity can be obtained by arranging an illumination intensity sensor.

[0074] During specific implementation, the acquired eye position information of persons in the vehicle may be position information, or relative position information or distance information relative to the glass of the vehicle. During specific implementation, the method of acquiring the eye position information may be real-time acquisition through a sensor, or the driver's eye ellipse position infor...

Embodiment 2

[0119] The difference between this embodiment and embodiment 1 is that after the shading starts, in embodiment 1, the eye position information (which can be a fixed value or a measured value at a set time) is directly based on the current illumination information and the eye position information of the personnel in the vehicle. , such as measuring after the seat is adjusted or the vehicle is started) to calculate the slope length of the shielding area and the target light transmittance on the vehicle glass and perform light shielding according to this, while in this embodiment, it is in the current light shielding state Next, calculate the slope length of the shielding area that needs to be changed and the corresponding target light transmittance. That is, the slope length of the shielding area on the carrier glass and the target light transmittance are calculated, and then the shielding area is adjusted according to the slope length of the shielding area on the carrier glass a...

Embodiment 3

[0136] Please refer to Figure 5 and Figure 6 , this embodiment proposes a sunshade device, which includes an illumination sensor 1, a controller and a sunshade component 2; specifically, the illumination sensor 1 is used to obtain illumination angle information and illumination intensity information.

[0137] The sunshade component 2 is a transparent liquid crystal display element, and the sunshade component 2 is installed on the carrier glass 3 . Through the transparent liquid crystal display part, the light transmittance of the transparent liquid crystal display part can be adjusted according to the needs, and a light-shielding area with a suitable size and position can be formed on the transparent liquid crystal display part, so that on the one hand, it can ensure sunshade with proper light transmittance , while preventing sunlight from interfering with the vision of people in the vehicle, it can also ensure that the shielding area has a certain degree of transparency, e...

Abstract

The invention discloses a sun-shading method, device and system for personnel in a traffic vehicle and an automobile. The sun-shading method comprises the steps: acquiring illumination information andeye position information of the personnel in a traffic vehicle; according to the illumination information and the eye position information of the personnel in the traffic vehicle, calculating the length of a slope of a shielding area located on vehicle glass and the target light transmittance; and forming a shielding area according to the length of the slope of the shielding area and the target light transmittance, so that the eyes of the personnel in the corresponding traffic vehicle are located in a shadow formed by the shielding area. The size of the shielding area and the light transmittance of the shielding area can be adjusted according to the illumination information, the view of a driver can be guaranteed to the utmost extent while sun shading is conducted, manual operation of thedriver is not needed in the sun shading process, and the driving safety is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile sunshade technology, in particular to a sunshade method, device, system and automobile for people in a traffic vehicle. Background technique [0002] During the driving process of the car, sunlight often passes through the front windshield and enters the driver's cabin. The sunlight will interfere with the driver's line of sight. Under strong light, it is very easy to cause traffic accidents. In order to avoid this phenomenon, sun visors are usually used to block sunlight in the prior art, so as to avoid or reduce the stimulation of sunlight to the driver's eyes. However, the existing sun visor requires the driver to turn it by hand, which will cause the driver to be distracted, and traffic accidents are prone to occur during the process of turning the sun visor. Contents of the invention [0003] The object of the present invention is to provide a sunshade method, device, system and automobile for pe...
