Self-adaptive driver forward anti-dazzle system and method

Abstract

The invention relates to a self-adaptive driver forward anti-dazzle system and method, and the system comprises a driving assistance camera module which recognizes the intensity of light emitted by a light source of an opposite driving vehicle, and locates the position information of the light source of the opposite driving vehicle; the control module is used for determining a light transmittance target adjustment area on a front windshield according to the intensity of light emitted by the light source of the vehicle running in the opposite direction and the light source position information, and determining the corresponding target light transmittance; and dynamically adjusting the corresponding light transmittance target adjustment area on the front windshield in real time according to the target light transmittance. According to the method and the device, the light transmittance target adjustment area on the front windshield is determined by identifying the intensity of the light emitted by the light source of the vehicle running in the opposite direction and positioning the position information of the light source of the vehicle running in the opposite direction, and the corresponding target light transmittance is determined, so that the corresponding light transmittance target adjustment area on the front windshield is dynamically adjusted in real time; the inhibition of forward strong light source glare of a driver is realized, and meanwhile, the forward normal visual field is not influenced.

Description

technical field [0001] The invention relates to the technical field of automobile driving, in particular to an adaptive driver's forward anti-glare system and method. Background technique [0002] During the driving process of the car, turning on the high beam of the oncoming vehicle at night and reflecting strong light from the vehicle ahead in sunny days will cause the driver to feel strong glare and discomfort. [0003] At present, there is no technology or equipment to effectively prevent forward glare in the actual loading of cars; most of the actual loading function is the automatic anti-glare device of the rearview mirror. The technical principle is that after the rearview mirror recognizes the strong light behind through the light sensor, Adjust the reflectivity of rearview mirror glass to suppress the intensity of light reflection, so as to achieve the purpose of automatic anti-glare rearview mirror. Although some of them have forward anti-glare function, the princ...

AI Technical Summary

Problems solved by technology

Although some of them have forward anti-glare function, the principle is to recognize the intensity of forward light through induction, and then calculate the light transmittance to be adjusted according to the intensity of forward light, and use forward electrically controllable anti-glare glass to adjust the glass transmittance. light rate, thereby reducing the overall light transmittance and preventing forward glare

This technology can prevent the glare effect caused by the forward glare to the driver, but because the overall light transmittance of the front windshield decreases while suppressing the glare, it also reduces the light intensity of the overall field of vision other than the glare, which is equivalent to affecting The overall clarity of the driver's field of vision, on the other hand, brings factors that affect driving safety, so this method is rarely used in actual mass-produced cars
