Description

Technical Field

Background

With the increasing requirements for vehicle driving safety, in the aspect of improving the driving safety of automobiles, the automobiles are all equipped with front windshield glass at present. The front windshield glass of the automobile is an indispensable part of the automobile body, has the functions of shielding wind and rain for passengers and drivers, and ensures the comfort of passenger riding and driver driving; however, the weather factor and the change of the driving environment are uncontrollable, the vision of the driver and the co-driver passengers is poor when the illumination intensity in the driving environment changes (such as the illumination intensity changes caused by entering and exiting tunnels, mountain holes and suddenly changing the driving direction, etc.) in the driving of the automobile, and the problem of fogging of the front windshield glass of the automobile is caused when the external environment temperature is lower than the temperature in the automobile, so that the potential safety hazard is caused to the driving of the driver, the front driver and the co-driver are extremely easy to be damaged when the automobile collides, and the privacy of the passengers is also lack of protection.

In order to avoid the above defects, two light shielding plates (one of which is hinged on the ceiling interior board above the driver's seat and the other of which is hinged on the ceiling interior board above the co-driver seat) are generally hinged at the front end of the carriage, and the vision of the driver is improved by manually opening a car lamp and an air conditioner, or the front windshield glass material is changed, so that the injuries to the driver and the co-driver during the collision are reduced, and privacy protection and the like are realized by manually sticking a film.

Improving driver vision in the above several ways has a significant drawback; when a driver needs to use the automobile, particularly in the driving process, the air conditioner, the light shielding plate and the automobile lamp are opened by hands, so that short-time attention of the driver is extremely likely to be not concentrated, driving safety is influenced, the light shielding plate can shield a certain visual field of the driver after being turned downwards (due to the light-tight characteristic of the material of the light shielding plate), driving experience is influenced, driving safety cannot be guaranteed, the head of a front driver and the head of a passenger can easily strike the windshield glass when collision occurs, safety of a front passenger cannot be guaranteed, and the like.

The inventor has not been provided with a device and a method for adaptively and rapidly changing the refractive index and the transmissivity of the front windshield glass through an illumination sensor through searching at present, so that the vision of a front driver and a passenger is effectively and rapidly improved, and the driving safety is improved. And there is no device for avoiding the fogging of the front windshield glass in a self-adapting way through a temperature sensor. The illumination and temperature sensor has the accurate and stable performance, and can accurately detect the changes of the light intensity and the temperature, etc.
