帶存儲功能的電動后視鏡
Electric rearview mirror with storage function
帶存儲功能的電動后視鏡在控制系統裝有驅動位置存儲器、回復開關和位置傳感器等。
The electric rearview mirror with storage function is equipped with drive position memory, return switch and position sensor in the control system.
操作電動后視鏡開關，電動后視鏡控制系統能調整后視鏡的位置。此外操作該系統的驅動位置存儲器和回復開關，可將調整位置存貯起來，在需要的時候回復到原來位置。
By operating the electric rearview mirror switch, the electric rearview mirror control system can adjust the position of the rearview mirror. In addition, operating the drive position memory and return switch of the system can store the adjusted position and return to the original position when necessary.
電變色后視鏡
Electrochromic rearview mirror
電變色后視鏡可根據眩目光的強度自動調節反射率。鏡片的處理工藝與變
The reflectivity of the electrochromic rearview mirror can be adjusted automatically according to the glare intensity. Processing technology and change of lens
色太陽眼鏡片所用的工藝相似。如果眩目光強烈，后視鏡便變暗，反射率減少大約6%。
The process of color sunglasses is similar. If the glare is intense, the mirror will darken and the reflectivity will be reduced by about 6%.
電變色后視鏡由采用兩塊導電玻璃中間夫一薄層電變色物質構成的鏡片和裝在后視鏡前后的兩只測定先強度的光電管傳感器及固體模塊等構成。夜間駕車時，后面汽車前照燈光來照到后視鏡上，后視鏡使會隨著光強而逐漸變暗。變暗的后視鏡，吸收眩目光。駕駛人可以通過一只三位置開關來選取后視鏡感光的靈教度。
The electrochromic rearview mirror is composed of two conductive glasses with a thin layer of electrochromic material, two photocell sensors and solid modules installed in front of and behind the rearview mirror to measure the initial strength. When driving at night, the rear-view mirror is illuminated by the front light of the rear-view car. The rear-view mirror will gradually dim with the light intensity. Darkened rearview mirror, absorb glare. The driver can select the sensitivity of the rearview mirror through a three position switch.

自動調節內后視鏡
Self adjusting interior mirror
當照到內后視鏡上的光線太強引起駕駛人不舒服時，自動調節內后視鏡便可自動地將后視鏡翹起。
When the light on the interior rearview mirror is too strong to cause discomfort to the driver, the automatic adjustment of the interior rearview mirror can automatically tilt the rearview mirror.
自動調節內后視鏡是利用裝在內后視鏡內的兩塊光電池來發出信號，其中一塊用來測定車內光線的強度；另一塊用來測定后視鏡受光的強度。若照到內后視鏡的光線強度大于車內光線的強度，并且超過預設值，則驅動內后視鏡的電磁線圈被激勵，將內后視鏡翹起。
The automatic adjustment of the interior rearview mirror uses two photocells installed in the interior rearview mirror to send out signals, one of which is used to measure the intensity of light in the car; the other is used to measure the intensity of light received by the rearview mirror. If the light intensity of the interior rearview mirror is greater than that of the interior light and exceeds the preset value, the electromagnetic coil driving the interior rearview mirror will be excited and the interior rearview mirror will be cocked up.
眩目內后視鏡
Glare interior rearview mirror
在液品里面放置偏光板，玻璃板被放置在經過真空鍍鋁的反光鏡的后面。當液晶間無電場時，入射光的垂直偏光被液晶染料部分吸收，透過光被著色反射出來。當染料進行光吸收時，透過光量增加，反射率提高35%一42%。
A polarizing plate is placed inside the liquid product, and the glass plate is placed behind the vacuum aluminized reflector. When there is no electric field between the liquid crystals, the vertical polarized light of the incident light is partially absorbed by the liquid crystal dye, and the transmitted light is colored and reflected. When the dye absorbs light, the amount of transmitted light increases and the reflectivity increases by 35% - 42%.
防眩目或非眩目交替操作不用人工，自動進行操作的裝置已實用化。反光鏡本體的一部分裝有光敏二極管的照度傳感器，能檢測后續車的前照燈照度并可進行切換控制。
The device of automatic operation without manual operation has been put into practice. A part of the reflector body is equipped with an illuminance sensor with a photosensitive diode, which can detect the illuminance of the headlamp of the follow-up vehicle and switch the control.
這種液品防眩目反光鏡的主要特征：一是防眩目或非防眩目時，反射面是同一的，所以視野不偏離；二是防眩目時不發生雙重映像；三是能夠自由選擇反射率（防眩目時反射率：棱鏡式約為4%，液晶式約為10%）。
The main characteristics of the liquid anti glare mirror are as follows: first, when anti glare or non anti glare, the reflecting surface is the same, so the field of vision does not deviate; second, when anti glare, there is no double reflection; third, the reflectivity can be freely selected (the reflectivity of prism type is about 4%, and that of liquid crystal type is about 10%).
