Bitauto News On December 6, the Ministry of Industry and Information Technology recently issued the "Interim Regulations on Automotive Radar and Radio Management" (hereinafter referred to as the "Regulations"). The "Regulations" propose that in order to promote the application of automotive intelligent technology and industrial development, the 76-79GHz frequency band is planned to be used for automotive radar.
The "Regulations" require that the main usage scenarios of the 76-79GHz frequency band include adaptive cruise control (ACC), collision avoidance (CA), blind spot detection (BSD), lane change assist (LCA), and parking assist. , rear vehicle warning (RTCA), pedestrian detection, etc. Setting up and using automotive radar in this frequency band does not require a radio frequency use license or radio station license, but it must comply with the requirements of the national road traffic safety, environmental protection, market supervision and management and other administrative departments.
It is understood that with the in-depth advancement of the new round of technological revolution and industrial transformation, the evolution of vehicle electrification, networking, and intelligent technologies is accelerating, and the performance of advanced driver assistance systems (ADAS) is continuously improved and widely used. , As one of the indispensable sensors, automotive radar is an important means to realize the intelligence of motor vehicles. Radio frequency is a key resource on which automotive radar work is highly dependent. In order to standardize and guide the use of radio frequency for automotive radar and reduce harmful interference between automotive radar and other radio services or stations, it is urgent to improve relevant management regulations.
The background for formulating the "Regulations" is that the rapid development of autonomous driving technology has put forward higher requirements for automotive radars in terms of resolution, detection accuracy and reliability. The existing frequencies of 24GHz and 77GHz frequency bands Planning is difficult to meet the technological development needs of automotive radar, and there is an urgent need to plan a larger bandwidth for its use frequency. Second, the 2015 World Radiocommunication Conference (WRC-15) made relevant resolutions to divide the 76-81GHz frequency band into a globally coordinated frequency band for automotive radar. Third, the 2019 World Radiocommunication Conference (WRC-19) divided the 24.25-27.5GHz frequency band into a globally coordinated 5G millimeter wave frequency. Some countries in the world have gradually guided the frequency band used by automotive radars to migrate to the higher 77GHz frequency band.
