Shulou(Shulou.com)11/24 Report--

CTOnews.com, March 11, 2022, on December 29, 2022, the national standard "performance and installation requirements of Motor vehicle indirect Vision Devices" was released, and it was officially implemented on July 1 this year, with the addition of "camera-monitor system", "mirror and CMS dual-function system" and so on.

One of the highlights of the new GB is that cars can not only install electronic rearview mirrors (CTOnews.com Note: CMS, full name Camera-Monitor System), but also replace the traditional optical rearview mirrors. This means that from July 1 this year, cars carrying CMS in China can be officially and legally mass produced.

According to the official release of Oufeiguang, by integrating the advantages of the three major product lines of vehicle camera, display screen and system controller, Ofeiguang launched a comprehensive solution for electronic rearview mirrors. This scheme can not only bring a wider field of vision and clearer images, but also reduce the wind resistance of the car, and even integrate rich ADAS functions to make driving more safe and comfortable.

At present, Oufeiguang has successfully won the designated projects of passenger cars from a number of car factories, and the product performance has been highly recognized by customers. At the same time, the company will accelerate the landing of the project and will achieve mass production after the implementation of the new regulations.

Compared with the common problems of the traditional optical rearview mirror, such as "incomplete vision", "unclear", "multiple interference", "large wind resistance" and so on, the electronic rearview mirror has the advantages of wide field of vision, reducing blind areas, automatically realizing light compensation, and being less affected by the environment, and can effectively reduce wind resistance and wind noise, and achieve energy saving and emission reduction. Ou Feiguang produced media rearview mirrors for domestic car companies in 2018. In the same year, he tried to install electronic rearview mirrors for another car company and completed the development and mass production of the first generation of electronic rearview mirrors. Oufeiguang independently completed product technology development in the field of electronic rearview mirrors in 2022, and won the designated domestic high-end intelligent electric vehicle project, which will achieve mass production after the implementation of the new regulations.

The left and right outer arms of the Ofeiguang self-developed electronic rearview mirror are each equipped with a 2m camera with heating function, and two 7-inch display screens are used in the cabin, which has the characteristics of fast start, low delay, large field of view, excellent picture quality, multi-function and high reliability.

When the vehicle battery is powered off, powered on, or the whole vehicle wakes up during sleep, the user can quickly display the high-definition screen in 1 second as soon as the user pulls the car door. From the camera shooting, transmission to the display screen, the whole process takes only 35 milliseconds to ensure a stable display at high speed.

When ▲ pulls the door, the display screen within 1 second can expand the field of view to HFOV63 °x VFOV23 °in special driving scenes (such as parking and turning) on the basis of the default visual field HFOV39 °x VFOV34.9 °, so that the display field of view is in an ideal state and the blind area of visual field is reduced to the maximum.

▲ reversing mode, automatically expands the rear field of vision

▲ steering mode, automatically expand the rear view of the steering side from the camera input of the external rearview mirror to the picture end of the display screen. Ofco implements the whole process management of image quality and continuously optimizes the image quality. Even at night, extremely dark and other poor light driving environment, it can also achieve high-definition image display effect. At the same time, through the lens internal FPC heating design, so that the camera in the rain, snow, fog and other harsh environment, to achieve the effect of de-icing and fog, and capture a clear rear view picture.

▲ extremely black mode, CMS clear display

▲ heating design, to achieve the effect of deicing and fog removal Ofi optoelectronic rearview mirror with its own brightness sensor, can adaptively adjust the display brightness according to the ambient light, more in line with human eye habits, but also can manually adjust the backlight brightness according to the button. In addition, CMS can also integrate ADAS functions to achieve blind area alarm, door early warning and other functions. When monitoring and alarming in the blind area, it can provide early warning information display and visual field switching, and can provide five kinds of display visual field positions, which can be customized according to the driver's habits.

▲ tunnel driving, CMS adaptive display brightness Ofi has a systematic functional safety solution, and has mass-produced products with functional safety system to ensure the stability of the system.
