Automatic anti-dazzling system of front windshield of car

Abstract

The invention provides an automatic anti-dazzling system of a front windshield of a car. The automatic anti-dazzling system comprises a front vision module, a cab vision module, a control module and an anti-dazzling module. The front vision module is used for monitoring position and strength of light emitted into the front windshield. The cab vision module is used for monitoring positions of eyes of a driver. The anti-dazzling module is arranged on the front windshield and used for regulating shading of the front windshield. According to the technical scheme, the control module is used for determining the position of the anti-dazzling module where dimming is needed for realizing light shading according to the strengths and positions of light sources in front of the car and position information of eyes of the driver, so that strong light can be prevented from irradiating to the eyes of the driver in time.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automatic anti-glare system for a front windshield of a vehicle. Background technique [0002] When the vehicle is driving at night, it is necessary to turn on the headlights for lighting. In most cases, turning on the low beams can meet the driving lighting needs. In the case of poor lighting, temporarily turn on the high beams. Or when passing cars, switch to low beams in time; however, due to negligence or lack of safety awareness of some drivers, they still turn on high beams when meeting cars, causing the oncoming driver to be dazzled, and traffic accidents are very likely to occur. On existing vehicles, there are no protective measures for this situation. For the dazzle caused by turning on the high beam of the opposite vehicle, only the experience of the driver can be used to perform "blind" operation, which is extremely dangerous.

[0002] When the vehicle is driving at night, it is necessary to turn on the headlights for lighting. In most cases, turning on the low beams can meet the driving lighting needs. In the case of poor lighting, temporarily turn on the high beams. Or when meeting cars, switch to the low beam headlights in time; however, due to negligence or lack of safety awareness of some drivers, they still turn on the high beam lights when meeting cars, causing the oncoming driver to be dazzled, and traffic accidents are likely to occur

On the existing vehicles, there is no protective measure against this situation. For the dazzle caused by turning on the high beam of the oncoming vehicle, only the driver's experience can be used for "blind" operation, which is extremely dangerous.

[0003] In the prior art, in order to avoid the occurrence of dazzling phenomenon, colored glass is used as a whole, but the light transmittance of the front windshield glass is reduced, making it difficult for the driver to see the road conditions in general, and it is still easy to cause accidents; therefore, At present, there is an urgent need for a device that can ensure normal light transmission under normal circumstances, and can effectively prevent the driver from being dazzled when strong light appears to ensure driving safety.
