As the key hardware of the autonomous driving perception layer, the vehicle-mounted intelligent sensor is not only related to the military unmanned ground vehicle system but also related to the automatic driving technology of civilian vehicles, which seriously affects the national defense security and industrialization development of China. In recent years, the United States has issued export control measures related to chips and software, which have seriously affected the development and safety of China's automotive smart sensor industry. At present, autonomous driving is in the transition stage from L2 to L3. Grasping this technological transition period may enable China to achieve corner overtaking and break the monopoly position of European and American countries in the field of on-board smart sensors. This paper summarizes the development trend of vehicle-mounted smart sensors under the background of autonomous driving, analyzes in detail the major challenges that affect the development and safety of China's vehicle-mounted smart sensor industry, and puts forward relevant suggestions to deal with the safety of industrial development.
