In the process of automobile intelligence, vehicles are bound to become more and more safe and convenient, and many traditional parts and components are also undergoing tremendous changes. For example, changes in car rearview mirrors:As the new national standard GB15084-2022 has been officially implemented in July 2023, it has become possible to replace traditional optical mirrors with electronic exterior rearview mirror CMS products with cameras + displays.

Congratulations on the successful holding of the 2nd Electronic Rearview Mirror CMS Industry Forum in 2024


CMS has obvious advantages over traditional optical mirrors, such as clear vision in rain and snow; driving at night without being affected by rear lights; reducing blind spots; in addition, through the combination with the ADAS system, it can also Important information is marked to serve as a reminder and warning to the driver. The most direct thing is that it can also reduce wind resistance and noise, achieve lightweight, etc., thereby improving driving economy, and has obvious advantages in commercial vehicles and electric vehicles.

Congratulations on the successful holding of the 2nd Electronic Rearview Mirror CMS Industry Forum in 2024

Of course, the CMS industry still faces many problems in the subsequent development. For example, users have insufficient knowledge of CMS products, and user usage habits also need to be further cultivated. On the other hand, in order to obtain a good user experience, the CMS system must With high reliability, low latency, high temperature and low temperature resistance, etc., this inevitably places higher performance requirements on the electronic components of the system - the screen module and the camera module, resulting in a higher cost of the overall CMS system. So, how to deal with the contradiction between cost and performance, promote user confidence in products from a technical level, and thereby accelerate industry development?
