Rearview mirrors have existed in cars for nearly a hundred years and are one of the oldest car parts. However, when cars were first invented, there was no such thing as a rearview mirror, and even the awareness of safe driving had not been established, let alone traffic rules. So at that time, when people wanted to turn when driving, they had to turn their heads to observe the situation behind the car.
It was not until the beginning of the 19th century that a legendary female racing driver appeared in Britain-Dorothy Levitt. Britain's first female racing driver set a record for the highest continuous mileage by a female driver in 1905 when she was 23 years old. Later, in 1906, she broke the women's highest speed record and was hailed as "the fastest woman in the world."
Due to long-term contact with cars, Dorothy Levy, with her unique female sensitivity and delicacy, observed the embarrassment and danger of not being able to understand the situation behind the car at any time while driving. Therefore, in his manual "Women and Cars" published in 1906, he mentioned the idea of using a mirror to observe the situation behind the car when there were many vehicles.
At present, traditional rearview mirrors have gone through a century of history, although the significance of rearview mirrors has been widely recognized by the public.
However, it also has four main disadvantages:The blind area of vision is large, which increases wind resistance, glare from the high beams of the vehicles behind, and disturbances caused by rain and snow.. These problems seriously affect the driver's judgment and control of the rear road conditions and vehicle driving status. Therefore, major automobile manufacturers have already planned to "eliminate rearview mirrors" and replace the rearview mirrors with imaging systems. However, due to legal regulations, they always stop at concept cars.
With the rapid development of vehicle-mounted intelligent terminal technology and the Internet, the automotive field has set off a revolution regarding the future direction of automobile rearview mirrors, which is the era of electronic rearview mirrors. Until 2016, when the EU ECE R46 was implemented, Japan and Europe successively began to explore the possibility of electronic rearview mirrors (CMS).
Since Daimler-Benz launched its electronic exterior rearview mirror project in 2008, there have been many car companies at home and abroad that have deployed electronic exterior rearview mirrors from concept cars to mass-produced models.
In the commercial vehicle market, the advantages of saving fuel and maintenance costs, ensuring night driving safety and reducing blind spots give CMS a broad commercial vehicle market. In 2018, Mercedes-Benz equipped its flagship model Actros with CMS. In 2020, Mann Trucks introduced the "zero blind spot" OptiView electronic exterior mirror system to replace the traditional rearview mirror. At present, there are a small number of domestic commercial vehicles equipped with electronic exterior rearview mirrors on the basis of traditional rearview mirrors, such as BYD K9 pure electric vehicles, Chenglong H9 tractors, and Shaanxi Automobile X6000 tractors.
In addition, in the passenger car market, CMS electronic exterior mirror cameras have also realized the transition from commercial vehicles to passenger cars. At present, overseas Europe and Japan have allowed CMS to replace traditional exterior rearview mirrors. Lexus ES, Audi e-tron and Honda E are currently in mass production. Domestic passenger cars equipped with CMS have already achieved mass production in 2022. BAIC Rubik's CubeBecame China's first mass-produced model equipped with electronic exterior rearview mirrors, In addition, Nezha S is equipped with electronic exterior rearview mirrors and was unveiled at the Shanghai Auto Show.

Traditional optical rearview mirrors on vehicles have a history of hundreds of years since their development in 1911. In terms of usage habits, humans may have long been accustomed to "seeing is believing". However, compared with traditional optical rearview mirrors, the advantages of electronic exterior rearview mirrors are obvious. They are called by the industry as rearview mirrors that truly have the ability to think. Its outstanding advantages are mainly reflected in three aspects:
First of all, it improves vehicle safety and gives drivers a wider field of vision. Electronic cameras can provide drivers with a wider field of view through wide-angle cameras, and unique algorithms can also bring a clearer driving experience.
Secondly, to reduce the probability of safety accidents, the use of digital correction technology can improve the imaging clarity in poor lighting conditions such as glare, darkness, rain and snow, tunnels, etc.; for example, traditional rearview mirrors are easily affected by raindrops on rainy days, and Electronic exterior rearview mirrors are less affected and can provide drivers with better visibility in rainy and foggy weather.
Finally, it reduces vehicle wind resistance, reduces fuel consumption, and improves vehicle power and economy. Data shows that car rearview mirrors can increase wind resistance by nearly 6%. If you switch to electronic exterior rearview mirrors, the wind resistance will be greatly reduced, and the fuel consumption will naturally be reduced.

01 New national standard introduced
While technology is evolving, regulations and supervision are also accelerating. At present, Europe and Japan are the first in the world to pass relevant regulations (ECE-R46 and Security Law) allowing vehicles to use electronic exterior rearview mirrors instead of traditional optical rearview mirrors, as cars develop in the direction of electrification and intelligence.
Today, as cars develop toward intelligence, automotive streaming rearview mirror products are gradually maturing. Countries have promulgated relevant standards, allowing electronic rearview mirrors to replace physical rearview mirrors. There are currently two main types of rearview mirrors on the market, namely mechanical optical rearview mirrors and electronic optical rearview mirrors. On December 29, 2022, our country promulgated the "Performance and Installation Requirements for Motor Vehicle Indirect Vision Devices" with the national standard number GB 15084-2022, adding "camera-monitor system" and "view mirror and CMS dual-function system" ” and other contents. This standard reclassifies the vehicle video surveillance system and adds safety warning information. It can detect the road conditions ahead, pedestrians and obstacles in real time while the vehicle is driving. The new standard will be implemented from July 1, 2023, bringing opportunities for domestic electronic exterior mirrors to be "onboard".
02 Mature plan and rapid growth
According to market estimates, global automotive electronic rearview mirrors will reach one trillion. As the CMS market faces full opening, some car companies have become pioneers, and some car companies have keenly sensed the market trend and started related layouts.
Audi, Mercedes-Benz, and Toyota are already at the forefront of mass-produced models equipped with CMS; later, Volvo, Honda, DAF, Dongfeng Liuzhou Automobile, Shaanxi Automobile, BYD, MAN, Hyundai and other manufacturers have also launched CMS-equipped models. models; in addition, manufacturers such as Weimar, Xiaopeng, and Lantu have also made relevant arrangements, waiting to catch up quickly when the wind blows.
The CMS electronic rearview mirror industry is still in its early stages of development, with high vehicle regulations and difficulty in development. The system's hardware and software technology are still being "updated". However, due to the scale effect and synergy with ADAS, it is expected to gradually become a mainstream.
Currently, CMS is still in its infancy, and the field of intelligent driving is also constantly advancing. It is committed to improving products and achieving volume step by step with controllable time costs, development costs, and hardware costs on the premise of meeting the differentiated needs of customers. Produce.
Recently, vehicles equipped with integrated black, large-sized displays have gained recognition among many consumers, becoming a hot topic in the industry.
