Autonomous vehicles make use of sensors to perceive the surrounding environment and make decisions. Currently，the widely used vehicle sensors including camera，ultrasonic radar，MMW radar and laser radar. With the improvement of the level of autonomous driving，the dashboard sensor has become much more important，and its market size has evidently expanded. With analysis of the development of status of domestic and foreign automotive sensors，this report believes that no single sensor can meet the needs of high-level autonomous driving，and the development direction of automotive sensors is multi-sensor fusion，Although the automotive sensor market is mainly monopolized by several major foreign manufacturers，but with the development of domestic sensor technology and quality improvement，relying on cost-effective advantages，the Chinese manufacturers will gradually replace imports products. Therefore，in order to promote the development of Chinese automatic driving vehicle sensors，first of all is to establish a sound vehicle sensor test evaluation system and test database，secondly，it is necessary to increase R&D investment for breaking through foreign technical barriers as soon as possible. It is also necessary to reduce sensor costs，especially the cost of laser lidar.
