Control method for glare elimination and visual optimization of automobile electronic mirror

Abstract

The invention discloses a control method for glare elimination and visual optimization of an automobile electronic mirror, which relates to the technical field of automobile electronic mirrors. The control method is characterized by comprising a lens calibration part and an algorithm control part. The lens calibration part comprises the step of acquiring a calibration curve S1, a calibration curveS2, a calibration curve S3 and a calibration curve S4. The algorithm control part comprises a plurality of control and calculation steps. According to the invention, the problem of dazzling of the electronic mirror when the glare is strong is effectively solved by reducing the reflectivity; the screen brightness is insufficient by coordinately controlling the simultaneous reduction of the reflectivity and the transmissivity; meanwhile, when the ambient light is dark, the purpose of being suitable for human eyes is achieved by adjusting the backlight brightness; and when the perspective rate of the LCD screen lens is insufficient, the reduction of the compensation light transmittance is achieved by improving the backlight brightness, the screen backlight brightness is effectively adjustedto a range suitable for a driver to watch, and adverse effects on the driving safety of the driver are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of an automotive electronic mirror, and more specifically relates to a control method for glare elimination and visual optimization of an automotive electronic mirror. Background technique [0002] The electronic anti-dazzling rearview mirror of the car adopts electrochromic lenses, and the headlight information of the rear vehicle is collected through light perception. Through a certain algorithm, the reflectivity of the lenses is controlled by adding a certain voltage to the electrochromic lenses, and the rear The light intensity from the mirror reflectance to the driver's eyes is controlled within a certain comfortable range to ensure the driver's visual safety. [0003] The Chinese patent whose publication number is CN105242418A discloses an automatic anti-glare automotive electronic rearview mirror, which includes a housing, a front glass substrate arranged on the housing, a rear glass substrate, a fron...

Problems solved by technology

[0004] However, during night travel, since the screen of the electronic rearview mirror still uses glass as the substrate, there is still glare from the rear headlights, which makes it difficult for the driver to see the displayed picture clearly. At the same time, when the ambient light is dark, It is difficult to adjust the brightness of the screen backlight to a range suitable for the driver to see, and in severe cases, the driver will be temporarily blind and unable to see, which will affect the driving safety of the driver and needs to be improved
