Automatic emergency braking system （AEB） can automatically detect the front the obstacles to determine the risk of collision and can sound the alarm and automatically implement the brake.Studies have shown that vehicles equipped with AEB can reduce the incidence of accidents by 27% and can significantly reduce casualties.The active safety technology，which is the core of the prevention of accident risk，has become an important direction for the development of modern automobile technology.AEB has greatly improved the active safety of the automobile，it has been widely used.This paper is divided into four parts.The first part summarizes the current situation of AEB both in home and abroad，and expounds the background and significance of this paper.The second part analyzes the existing AEB standards and regulations both in home and abroad and the classification of the regulations to be launched soon.The third part includes the in-depth analysis of key AEB standards and regulations and the research of the key technical indicators in China's applicability.The fourth partfocuses on the progress of the establishment of China's automatic emergency braking system standard and programs to establish a national standard for rational and economically feasible test method to promote，guide and standardize the development of China's active safety technology，improve vehicle safety performance and improve road safety.
