The invention discloses a multi-scene recognition frameless anti-dazzle inside rear-view mirror which is characterized in that a power supply processing module is used for converting external voltage into 3.3 V direct-current voltage and supplying power to other modules; the reversing signal module processes reversing signals input from the outside and transmits the reversing signals to the single-chip microcomputer control module. The ambient light sensor senses external illumination intensity, converts the external illumination intensity into digital signals and transmits the digital signals to the single-chip microcomputer control module. The dazzling light sensor senses the dazzling light intensity behind, converts the dazzling light intensity into digital signals and transmits the digital signals to the single-chip microcomputer control module. The single-chip microcomputer control module carries out scene judgment according to the illuminance signal and monitors whether an anti-dazzling threshold value is met or not, and if yes, a voltage signal is output; the inside rear-view mirror driving circuit receives the voltage signal and drives the inside rear-view mirror; the outside rear-view mirror driving circuit receives the voltage signal and drives the outside rear-view mirror. The reflectivity of the inner rearview mirror and the outer rearview mirror can be automatically adjusted according to the illumination intensity in different scenes, and therefore the driving experience is optimized.
本发明公开了多场景识别无边框防眩内后视镜,包括:电源处理模块将外部电压转换为3.3V直流电压,为其他模块供电;倒车信号模块处理外部输入的倒车信号并传输至单片机控制模块;环境光传感器感应外界光照强度并将其转化为数字信号传输给单片机控制模块;眩目光传感器感应后方眩目光照强度并将其转化为数字信号传输给单片机控制模块;单片机控制模块根据光照度信号进行场景判定,并监测是否满足防眩目阈值,若满足则输出电压信号;内后视镜驱动电路接收电压信号并驱动内后视镜;外后视镜驱动电路接收电压信号并驱动外后视镜。本发明能够根据不同场景下的光照强度自动调整内外后视镜的反射率,从而优化驾驶体验。
