Can you believe it?One of the biggest changes in domestic cars this year is that there are new cars that "abandon" the rearview mirrors!It's true to "ditch" the mirrors, but here we are referring to the traditional mirrors in favor of the new CMS electronic exterior mirrors. This fresh configuration actually appeared in some concept cars many years ago, but due to legal restrictions, it has not been mass-produced. In December last year, we promulgated the "performance and installation requirements for motor vehicle indirect vision devices" in the new "camera-monitor system", "mirror and CMS dual-function system" and other content, the new standard was implemented on July 1 this year, which means that the CMS electronic exterior rearview mirror has now been mass-produced in China. So what exactly is a CMS electronic exterior mirror?Why is it a better solution for blind spots?What kind of cars can you buy now that are equipped with CMS electronic exterior mirrors?Below we will bring you a full of dry goods.
Why develop CMS electronic exterior mirrors?
Before we understand the CMS electronic exterior mirror, we must first know why it appeared. Born in 1921, the traditional rearview mirror has a hundred years of development, at first it was only an optional configuration for cars, and the early rearview mirror was a one-sided, round plane mirror material, until the 60s of the last century began to become a mandatory accessory for cars on the road. In other words, the development of rearview mirrors is actually the process of people from not realizing the importance of the rear vision of the car to starting to find ways to ensure the rear vision. Over the years, although the rearview mirror has adopted measures such as double curvature, the installation of small round mirrors, and the addition of anti-glare protective film to improve the field of vision, the disadvantages such as blind spots, glare of rear car high beams, and interference in rain and snow weather have not been substantially improved.
On the other hand, the wind resistance and wind noise caused by traditional rearview mirrors are also one of the main factors affecting the driving comfort of car users and increasing the energy consumption of vehicles. We can see from the history of the development of the car form that the evolution of the shape of the car is basically the product iteration history of reducing wind resistance. Although some of the current rearview mirrors are already shaped to cater to aerodynamic design as much as possible, due to their physical characteristics, they cannot usher in a further breakthrough. In other words, while the traditional rearview mirror has more or less solved some problems, there are many problems that cannot be handled, and there is no "almost foolproof" solution and design.
Just as electricity solves kerosene lighting and opens the era of electrification by the way, the development of technology is often a dimensionality reduction blow that jumps out of tradition, and perhaps the solution is not to "external mirror" for a better vision. With the rapid development of global science and technology, ** and related technologies have been greatly improved, CMS electronic exterior mirror is one of the products of the era of automotive technology. CMS electronic exterior mirror is a combination of camera and display screen to replace the traditional optical rearview mirror - the external camera collects images, processes and displays them on the cabin display screen, which can provide a wider field of vision, realize automatic light compensation, and is less affected by the environment, and at the same time, with its smaller size, it can bring less wind resistance, front side blind spot and wind noise, becoming the best choice to replace the traditional rearview mirror and comprehensively improve driving safety.
At first, some brands only displayed this design on concept cars, until 2016, when the European Union's certification regulations for automotive electronic exterior mirrors were implemented, and Europe and Japan began to explore the road to mass production of CMS electronic exterior mirrors. In 2018, before the official debut of the Audi e-tron, the brand released an official image of the Audi e-tron with electronic exterior mirrors, claiming that it would be reduced by 0The drag coefficient of 01 can be increased by about 5 kilometers. However, at the time, this configuration was not roadable in a large part of the world.
In 2018, Lexus released the all-new ES, which became the world's first mass-produced passenger car model equipped with an electronic exterior mirrorIn 2019, Mercedes-Benz launched a new generation of top-of-the-line truck actors, which is the first truck in the world to be equipped with CMS as standard. There are many blind spots in the field of vision of the passenger car, and the difficulty of operation is much greater than that of the passenger car, and the inner screen of the electronic exterior mirror of the actors is designed with the calibration line of the trailer tail, and the owner can adjust the calibration line according to the trailer of different lengths, and effectively improve the distance measurement of the obstacle at the rear of the trailer to the centimeter level, which is conducive to accurate reversing and loading and unloading on the platform. For some extra-long trailers, the rear of the vehicle can be observed even when cornering at a small angle, such a "fragrant" configuration should be a blessing for all truck drivers, and no one will refuse technology that can turn a bulky truck into easy control. Because electronic exterior mirrors have also become a trend of a new generation of automotive products, and have formed a considerable popularity overseas, and the popularity of CMS for several years also means that CMS is not a whimsical marketing point, but a reliable and useful technology. For the domestic market, all that remains is the improvement of regulations.
In addition to a large field of view and low wind resistance, what else can CMS electronic exterior mirrors do?
In fact, there is still a lot of room for imagination in CMS electronic exterior mirrors. With the development of automotive intelligent driving technology and intelligent cockpit, CMS electronic exterior mirror will likely become an important part of the intelligent driving solution, such as integration with ADAS, integration with traditional driving cameras, integration of blind spot monitoring, parallel assistance and other functions, which can save car manufacturing costs in the long runOn the other hand, the integration of the intelligent cockpit will also become higher, and it can be integrated into the intelligent cockpit controller together with the in-car HUD, central control entertainment screen, LCD instrument, streaming ** rearview mirror and other screen display solutions to achieve unified management under the same chip, making data stream processing more efficient, and can achieve more direct rearview mirror angle adjustment through the touch screen. In other words, under the general trend of intelligent driving, CMS electronic exterior mirrors can be more organically integrated with the vehicle system compared with traditional rearview mirrors. These are the future development trends of CMS electronic exterior mirrors, in the foreseeable future, with the continuous breakthrough of CMS electronic exterior mirrors, our travel can become more convenient and safer.
What are the cars equipped with CMS electronic exterior mirrors in China?
On July 1 this year, with the official implementation of the "new national standard", the domestic CMS electronic exterior rearview mirror was officially launched. For example, the Lotus pure electric high-performance SUV Eletre has launched a stream ** exterior mirror option, and the optional ** is 160,000 yuan;AVATAR's luxury medium and large electric sedan AVATR 12 also provides optional electronic exterior mirrors, optional ** is 120,000 yuan. In the field dominated by multi-person travel MPV, SAIC MAXUS large family luxury electric MPV everyone 7 also provides CMS electronic exterior mirror option, becoming the world's first MPV equipped with CMS electronic exterior mirror, its optional ** is 5000 yuan.
The CMS electronic exterior mirror area of the 7 is reduced by more than 50% compared with the traditional rearview mirror, and this configuration reduces the wind resistance of the whole vehicle of the 7 by 3%, which can bring a very considerable range improvement and lower wind noise for pure electric models. In addition, the field of view of the electronic exterior mirror is also 28 times. The CMS electronic exterior mirror also brings a simpler and more convenient way to adjust, just like adjusting the camera function of a mobile phone, just swiping your finger on the screen to adjust the picture, improving operation efficiency and driving safety. In addition, it comes with a lens heating and water removal function, which can have a clearer, wider and stable field of vision when driving at night, rainy days and foggy bad weather, and also supports dynamic automatic adjustment during driving, and the shortcomings of traditional rearview mirrors have been solved, comprehensively improving driving safety.
CMS electronic exterior mirror is undoubtedly an innovative technology empowered by science and technology, and the smaller size can provide a more stable, clearer and larger vision, which has further improved both the car experience and driving safety. Friends who are interested in this technology can go to the brand store to test drive the experience, I believe you will be difficult to use it.
