Before CA Auto China convened the GB 7258 seminar, various companies had submitted their opinions to relevant departments. Therefore, at this symposium, the participants discussed the feasibility of revising opinions from a technical perspective.
Chao Yang, deputy director of Traffic Safety Research Department II of the Ministry of Public Security Traffic Management Research Institute, told the “Commercial Automotive News†reporter: “We certainly hope that vehicles can use the safest structures and installations. The standard requirements for these devices are at this stage. If we have better products and technologies, we will certainly adopt them. We will listen to the opinions of all parties and consider them comprehensively. It will take a while for the revised version to be issued."
“The meeting was well discussed.†A bus company official at the conference told Commercial Automotive News: “The standard has dozens of pages. The seminar is discussed one by one, mainly discussing microscopic, technical, and design. To the extent that manufacturing and equipment are feasible and can not be achieved, the impact on macroeconomics is less discussed. This revision was led by the Ministry of Public Security, and the Ministry of Public Security, the Ministry of Industry and Information Technology, and the Ministry of Transport participated in the revision. The starting point for revising the draft is good. It will help promote the development of the automotive industry and improve the safety of automotive products, but it must also fully consider the actual situation in the country. Too strict requirements are not conducive to industrial development."
