The invention relates to a system and method for adjusting the refractive index of a vehicle-mounted sun shield. The system comprises a power supply unit, a control unit and the sun shield, wherein the sun shield comprises a refractive index adjusting unit and transparent material layers, and the refractive index adjusting unit is a color-changing material layer of the sun shield and is located between the two transparent material layers; the control unit is mounted above the sun shield; the control unit is connected with the refractive index adjusting unit; the power supply unit is used for providing power for the vehicle-mounted intelligent sun shield system; and the control unit is used for applying voltage to the refractive index adjusting unit to adjust the transmittance of the refractive index adjusting unit. According to the invention, the refractive index of the sun shield can be changed by applying voltage; the system can reserve the original sight range of a driver; and the system can reduce the weight and thickness of the sun shield.

    本发明涉及一种车载遮阳板折射率调整系统及方法,系统包括供电单元、控制单元和遮阳板;所述遮阳板包括折射率调节单元和透明材料层,所述折射率调节单元为遮阳板的变色材料层,位于两层透明材料层之间;所述控制单元安装于遮阳板上方;所述控制单元与折射率调节单元连接。所述供电单元用于为车载智能遮阳板系统提供电力;所述控制单元用于给折射率调节单元施加电压,来调节折射率调节单元的透射率。本发明能够通过施加电压来改变遮阳板的折射率;系统能够保留驾驶员的原视线范围;系统能够降低遮阳板重量与厚度。
