Knowing about the development status and learning from the advanced experience of the autonomous driving（AD）industry in the United States and Europe would helps us to explore the road of the development of autonomous vehicle，and provide direction reference for national macro policy guidance，top-level design and strategic tasks. It also promotes the industrialization process of China’s AD and the independent R & D and iterative innovation of related technologies. The UNECE WP.29 issued the first mandatory AD regulation（ALKS-UN Regulation 157），also issued regulations on preventing cyber threats（UN Regulation 155）and faulty software updates（UN Regulation 156）. The United States has issued the “Surface Transportation Reauthorization Act” and “Federal Motor Vehicle Safety Standards” and etc. to lay the foundation for the development of the AD industry. The AD technology comprehensive plan is issued to prepare the traffic system for the safety of autonomous vehicles. At the same time，the Federal Communications Commission has designated specific frequency bands for intelligent transportation systems. In terms of vehicle manufacturers，GM，Ford，Hyundai，Tesla and other enterprises have launched a high level automatic driving vehicle program. In Europe，regulation（EU）2018/858 provides a unified legal framework for the type approval and marketing of new motor vehicles in the EU. Germany and France revised road traffic regulations to introduce AD into routine operation. The OpenX standards of ASAM unifies the data format and interface for AD simulation test. At present，the outbreak of COVID-19 and the frequent occurrence of traffic accidents on autonomous vehicles have delayed the OEMs to launch the expected autonomous vehicles. The overall commercialization and landing of AD in the world still need technical development，such as environmental sensors and other core components，and the improvement of laws and regulations.
