[guide] the opening of the test area is imminent. The opening of various scenes and road sections helps to make the vehicle run in with the actual environment more frequently, and focus on the running in in when there are more potential safety hazards, so as to make the vehicle more intelligent.
Last week, we just focused on flying cars to explore their travel convenience in severe weather and heavy ground traffic pressure. Obviously, driving license, laws and regulations and other environmental conditions are not mature, so automatic driving is still feasible on the "road".
Therefore, domestic and foreign automobile manufacturers and technology giants have increased their size and layout. Now Tesla has set up a factory in Shanghai, and today Jaguar Land Rover has set up a research and development center in Ireland. Waymo also announced that the road test mileage of its automatic driving team has reached 8 million miles, further to the real no one on the road.
New and old players continue to break through the technology and testing, followed by a wider range of scenarios, the diversification of application services. Recently, it has expanded in taxi and robot intelligent logistics. It also highlights the development of manned testing and shared cars.

Driverless taxis carrying passengers test sharing cars are also driverless
Japanese taxi giant "Nippon transportation" and start-up ZMP announced on July 18 that at the end of August, they will carry out the passenger carrying test of self driving taxis in the central area of Tokyo Metropolitan Area, and start the recruitment of test passengers. This is the world's first self driving taxi with passengers, and in the road to pay for passenger driving test.
Unlike private cars and public transportation, the self driving taxi is a good supplement to personal commuting. The development of self driving taxis in Tokyo is still for the preparation of the Tokyo Olympic Games. We hope to reflect the high-tech driverless technology in front of the world, and also deal with the traffic pressure brought by the peak passenger flow.
In addition to the expansion of taxi applications, driverless has also recently focused on the sharing of cars. In the early stage of the development of shared cars, because of the high operating cost, narrow crowd, inconvenient use and other problems, the market has questioned, so it is necessary to strengthen the user experience of shared cars. A platform has put forward the shared cars of new energy vehicles or driverless shared cars.
Recently, Baidu and Wanda automobile have jointly developed valet parking, a commercial automatic driving product, and tested it in a closed Park in Chongqing.
The product has the functions of fixed-point remote calling, autonomous parking and automatic charging. Meanwhile, it can complete traffic light recognition, pedestrian and obstacle avoidance and other actions. Baidu claims that it has realized the transformation of shared cars from "people find cars" to "car find people", and solved the problem of "the last kilometer" of shared cars. At the same time, it can reduce the operation cost for the sharing car operators, so as to realize the commercial landing of automatic driving products in the actual operation scenario.
High precision maps and test sections are back-up AIDS
With the increasing application scenarios of automatic driving, the ability of road recognition of vehicles is also challenged. For example, for the needs of taxis and automatic parking, there are higher requirements for the precise route and map accuracy of some sections. Therefore, the map accuracy required for automatic driving is usually centimeter level. In the unmanned state, the difference is millimetre and the error is thousands of miles, and the mappers have become the focus of the joint efforts of automobile manufacturers. There are Baidu map, Gaode map and Tencent map in China, here, Google map and new Apple map in foreign countries, but there will be more new members of the above camp in the future - Jingdong map. After bat gathered in the map market, Jingdong came to layout again, which is also an emerging field after the four giants gathered in social, e-commerce, entertainment, streaming media and other fields.
In a recent appearance, JD said that JD map mainly provides automatic driving services for robots, and unmanned logistics for robots will increase research and development.
At the same time, it also claims to have a full process production system from data collection, processing, release and application. The production process is highly automated, covering social roads, park roads, indoor and many other scenes. With the help of the multi carrier 3D laser mobile measurement system independently developed by Jingdong, the map of Jingdong can realize the automatic recognition of the real road surface, obstacles, surrounding environment and other features.
The accuracy of high-precision map needs data collection from the grass-roots level, rooted in the specific road section to collect road information, and also needs real-time update, using crowdsourcing is particularly effective.
After all the preparations are complete, the next step is the road test phase of automatic driving, and the practical test is the proof of ****. Therefore, since this year, there have been open test sections in Beijing, Shanghai, Guangzhou, Chongqing and other places, and test licenses have been issued to vehicles. In the open sections that are as close to the real scene as possible, Baidu, Weilai automobile, BAIC, SAIC, BMW, Mercedes Benz Daimler and other foreign countries have successively obtained licenses. They have continuously accumulated test experience in complex scenes and repeatedly ground vehicle performance Improve vehicle stability and emergency handling capacity.
Recently, Zhaoqing auto driving city road test demonstration zone was officially established, which is also the city level demonstration zone of * * * auto driving in mainland China. Zhaoqing high tech Zone and Zhaoqing new area are selected as the demonstration area, with 33 urban roads covering 60 kilometers. On the other hand, for the enterprises that meet the conditions of open road test, the total open road test conditions of more than 60 kilometers are provided, and its rich traffic road resources cover the most of the urban traffic road components and lines
