Description

technical field [0001] The present invention relates to the field of automobiles, and more specifically, to an automatic driving system. Background technique [0002] Automobile is an indispensable means of transportation in people's daily work and life. The rise and fall of the huge auto market also largely affects the development of the global economy. The research and development of self-driving car technology has a history of decades in the 20th century, and it has shown a trend of being close to practical application in the early 21st century. For example, Google's self-driving car obtained the first self-driving vehicle in the United States in May 2012 The license is expected to enter the market from 2015 to 2017. [0003] Self-driving cars rely on artificial intelligence, visual computing, radar, surveillance and global positioning systems to work together to allow computers to automatically and safely operate motor vehicles without any active human intervention.
