Problems solved by technology

[0002] When driving at night, if the high beam of the rear vehicle is illuminated, strong reflected light will be generated in the interior rearview mirror to dazzle the driver. The dazzle will delay the driver's operation response and seriously affect driving safety.
In addition, strong light is easy to make people's eyes tired and affect the driver's health.
[0003] In the prior art, most cars use manual anti-glare rearview mirrors, which require the driver to manually adjust the angle of the rearview mirror to prevent glare, the effect is general and easily distracts the driver

Abstract

The invention provides a control method and a control system of an anti-dazzling rearview mirror. The method comprises the steps: acquiring a light intensity signal in front of a vehicle and a light intensity signal behind the vehicle; calibrating the light intensity signal in front of the vehicle to obtain an actual light intensity signal in front of the vehicle; determining the current state of the anti-dazzling rearview mirror; calibrating the light intensity signal behind the automobile according to the current state of the anti-dazzling rearview mirror, and acquiring an actual light intensity signal behind the automobile; and determining a voltage output control strategy for the anti-dazzling rearview mirror according to the actual light intensity signal in front of the vehicle, the actual light intensity signal behind the vehicle and the current state of the anti-dazzling rearview mirror. Based on the technical scheme provided by the invention, the light intensity signal in front of the vehicle and the light intensity signal behind the vehicle are respectively calibrated to obtain an actual light intensity signal in front of the vehicle and an actual light intensity signal behind the vehicle, so that the detection error of the photosensitive sensor can be reduced as much as possible, the reliability of an anti-dazzling algorithm is ensured, and the anti-dazzling rearview mirror can respond normally; and therefore, user experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobile rearview mirrors, in particular to a control method and system for an anti-glare rearview mirror. Background technique [0002] When driving at night, if the high beam of the rear vehicle is illuminated, strong reflected light will be generated in the interior rearview mirror to dazzle the driver. The dazzle will delay the driver's operation response and seriously affect driving safety. . In addition, strong light is easy to cause eye fatigue and affect the driver's health. [0003] In the prior art, most automobiles use manual anti-glare rearview mirrors, which require the driver to manually adjust the angle of the rearview mirror to prevent glare, which is generally ineffective and easily distracts the driver. With the rapid development of automobile technology, users have higher and higher requirements for automobile experience. Therefore, how to propose a safer and better automatic anti-d...
