Why is the electronic exterior mirror started to rise? Due to the situation we often encounter: the visual field of the traditional outer rearview mirror is fixed; poor definition at night or in dim environments; in severe weather, especially rainy or snowy days, the sight line can be disturbed due to the observation of side windows covered by rain and snow at intervals; side windows and exterior mirrors are prone to fogging in winter, affecting vision, etc., however these problems can be easily resolved in electronic exterior mirrors, thereby improving safety.

Specifically, an external camera with high resolution is adopted on the electronic outer rearview mirror, and a high dynamic range imaging technology HDR is used for automatically compensating light so as to realize brightness adjustment. Meanwhile, a plurality of coatings are added to the outer layer of the camera and the heating function is provided, so that the surface of the camera is still clean when the camera encounters rainy, snowy and sandy weather, and clear imaging is provided. And a high-definition screen positioned in the vehicle is not influenced by the window of the vehicle any more even under severe conditions. In addition, when turning on the steering lamp to turn or merge, the electronic outside rearview mirror can provide a wider visual field to eliminate blind areas.
