Abstract
The utility model discloses an electronic anti-dazzle system for a vehicle. The front wind shield of a vehicle consists of two ordinary glass layers, and a liquid crystal layer is arranged between the two ordinary glass layers; a sunlight illumination angle sensor and a driver eye view angle sensor are arranged on the front wind shield, and the output ends of the sunlight illumination angle sensor and the driver eye view angle sensor are connected with an electrical control unit (ECU); an output end of the ECU is connected with the liquid crystal layer; and a black matrix area is formed on the liquid crystal layer by the ECU according to signals input by the sunlight illumination angle sensor and the driver eye view angle sensor. The system effectively avoids the interference of the sunlight on the driver so that a user only needs to turn on the system without any operation. Relative to the traditional sunshade system, the system can prevent sunshade failures caused by turning or swinging of the vehicle, thereby greatly improving the driving safety and comfortableness and meeting the requirement on hommization.
Description
Technical field
The utility model relates to a kind of automotive window sunshade tool, especially relates to a kind of auto electronic no-glare system.
Background technology
During driving, if you travel eastwards in the morning or westwards travel between the lights, dazzling sunlight always sees through front windshield and injects in the car, influences driver's sight line, brings inconvenience, even influences driving safety.For sunshade, also propose to use many sunshade tools, though be to have played certain effect, no matter which kind of mode, more or less because automobile turns round or rocks and causes light still to be injected in the car, still can have influence on driver's traffic safety.
The utility model content
The utility model has designed a kind of auto electronic no-glare system, and it has solved outside window that sunray can produce the technical matters of disturbing to vehicle driver's vision.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
A kind of auto electronic no-glare system, the front windshield of self-propelled vehicle is made of two simple glass layers, between described two simple glass layers, be provided with a liquid crystal layer, on described front windshield, be provided with solar light irradiation angular transducer and driver's eyes visual angle sensor, the mouth of described solar light irradiation angular transducer and driver's eyes visual angle sensor is connected with an ECU (Electrical Control Unit) ECU, and the mouth of described ECU (Electrical Control Unit) ECU is connected with described liquid crystal layer; Described ECU (Electrical Control Unit) ECU forms a matrix black region according to the signal of described solar light irradiation angular transducer and the input of driver's eyes visual angle sensor at described liquid crystal layer.
Further, described solar light irradiation angular transducer is positioned at the outside of described front windshield, and described driver's eyes visual angle sensor is positioned at the inboard of described front windshield.
Further, described matrix black region is rectangle or rhombus.
Further, described ECU (Electrical Control Unit) ECU is connected with described liquid crystal layer by a signal wire (SW).
This auto electronic no-glare system has following beneficial effect: the utility model is owing to can produce the sunlight that directive driver eye position is blocked in a translucent black zone on Windshield, effectively avoided of the interference of sunshine light to chaufeur, the user only needs open system, need not any operation, traditional relatively shading system, this system needn't worry to cause the sunshade failure problem because of vehicle turns round or rocks, and improves drive safety, traveling comfort greatly, meets the hommization requirement.

The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3, the utility model is described further:
As depicted in figs. 1 and 2, a kind of auto electronic no-glare system, the front windshield 9 of self-propelled vehicle is made of two simple glass layers 5, between described two simple glass layers 5, be provided with a liquid crystal layer 6, on described front windshield 9, be provided with solar light irradiation angular transducer 1 and driver's eyes visual angle sensor 2, the mouth of described solar light irradiation angular transducer 1 and driver's eyes visual angle sensor 2 is connected with an ECU (Electrical Control Unit) ECU3, and the mouth of described ECU (Electrical Control Unit) ECU3 is connected with described liquid crystal layer 6; Described ECU (Electrical Control Unit) ECU 3 forms a matrix black region according to the signal of described solar light irradiation angular transducer 1 and 2 inputs of driver's eyes visual angle sensor at described liquid crystal layer 6.
Described solar light irradiation angular transducer 1 is positioned at the outside of described front windshield 9, and described driver's eyes visual angle sensor 2 is positioned at the inboard of described front windshield 9.
Described ECU (Electrical Control Unit) ECU3 is connected with described liquid crystal layer 6 by a signal wire (SW) 7.
As shown in Figure 3, the principle of work of this auto electronic no-glare system is as follows: when sunshine light beam 8 from front upper place directive front windshield 9, solar light irradiation angular transducer 1 collects the irradiation angle of sunshine, driver's eyes visual angle sensor 2 collects the driver vision angle simultaneously, both send signal to ECU (Electrical Control Unit) ECU3, ECU (Electrical Control Unit) ECU3 judges those little liquid crystal displays that will start on the described liquid crystal layer 6 by setting program, again signal is passed to liquid crystal layer 4, just can generate the light black radiance so receive the little liquid crystal display of signal, form matrix black region 11, this matrix black region 11 is the zones of joining of sunshine light beam 8 and pilot's line of vision 10, this zone is shown with translucent black, effectively prevented the interference of sunshine pilot's line of vision.
When vehicle traveling direction change or car body rocked, solar light irradiation angular transducer 1 and driver's eyes visual angle sensor 2 be acquired signal again, regenerates new matrix area, has improved drive safety, traveling comfort greatly, meets the hommization requirement.
