First, regulatory issues. We know that Chinese car regulations is basically in accordance with ECE regulations (car regulations of the United Nations Economic Commission for Europe) combined with the local characteristics of the development, at present, the GB regulations yet to matrix headlight legislation to make detailed technical requirements, refer to major domestic car companies in the design of this system is the ECE regulations.
Second, R & D and manufacturing capabilities. Matrix headlamp is a system engineering, not only more powerful than the lane assist system image processing ability, but also need the lamp supplier very high light distribution technology and high precision light source module manufacturing ability. As far as we know, most domestic suppliers do not have the development capability of the matrix headlamp system in China, except for individual suppliers.
Third, cost issues. The application of high-tech intelligent products can not escape a cost problem at last. The cost of the matrix headlamp system is even more than several times that of an ordinary LED headlamp, which is a great pressure for most of the hot models on the market. Of course, part of the cost, such as the camera can be shared with Lane assistance, automatic parking and other functions, so many of the current model of the matrix headlamp configuration and lane auxiliary lights function is a binding relationship.
In fact, SAIC provides matrix headlight configuration as early as two years ago Weilang GS, soon to be listed Regal is the configuration matrix of headlight second models. This should be the general attention to the application of advanced technology, for consumers to reflect a reflection of it.
As mentioned above, matrix LED headlamps cost very high, where is the specific height? We look at the new Regal headlights, this is a huge systematic project, two aspects of hardware and software are indispensable.
Need suspension stroke sensor, steering angle sensor, light sensor, light control module and the most important point -- high resolution camera hardware, and has a great demand for manufacturing capacity, especially the manufacturing precision of light source module.
The matrix headlamp can take into account both curve lighting
The software needs powerful image recognition and processing function. Because of the requirement of data transmission and response time, the communication between the system is completed through the CAN bus. These systems work together to create such an intelligent lighting system, so that the car can respond to changes in the environment, accurate and rapid response, providing the required lighting mode.
The difference between a conventional LED headlamp and a traditional headlamp is probably just the replacement of the light source. Its complexity and matrix headlamps are not comparable. The complexity of matrix headlamps is also a challenge to the supplier's R & D capability and manufacturing capability. As far as we know, the cost of the matrix headlamp system is even several times, or even ten times as much as that of an ordinary LED headlamp.
The development of matrix headlamps is in Europe, and even to say, the revolution in automotive lighting technology is European led. Buick Regal is a pure European Blood beauty car, keep a same level leader in the direction of it is not difficult to imagine the original designers in lighting technology.
With the accumulation and development of technology, especially the trend of intelligent vehicles, the equipment of matrix headlamps will be more and more. With the promotion of the competitiveness of independent brands, and gradually enter the high-end market, the application of matrix headlamps will become more and more common.
