It is reported that driverless technology is changing life and the face of the city. In China, driverless vehicles have been formally introduced into the logistics and express industry. The unmanned express car has reduced the labor cost, so it is quite attractive.
It is reported that the United States and Europe have always been in a dominant position in the R & D competition for autonomous vehicle. However, China is also catching up and will overtake on the curve through policy regulation. In the future, China may surpass Europe and the United States and other technological powers in the popularity of autonomous vehicle.
In recent years, "driverless" as a hot word of science and technology has frequently appeared in the public's field of vision. Referring to the classification definition of automatic driving by the society of automotive engineers, according to the degree of intelligence, automatic driving is divided into five levels: L1 refers to auxiliary driving, L2 refers to partial automatic driving, L3 refers to conditional automatic driving, L4 refers to highly automatic driving, and L5 refers to fully automatic driving, that is, real unmanned driving. The concept of "unmanned driving", which is increasingly active in the public eye, often refers to automatic driving at L3 and above.
The core technology system of unmanned driving can be divided into three levels: perception, decision-making and execution. The sensing system is equivalent to human eyes and ears, which is responsible for sensing the surrounding environment and collecting and processing environmental information and in vehicle information, mainly including vehicle camera, laser radar, millimeter wave radar, ultrasonic radar and other technologies. The decision-making system is equivalent to the human brain, which is responsible for data integration, path planning, navigation and decision-making. It mainly includes high-precision maps, Internet of vehicles and other core technologies. The executive system is equivalent to the human cerebellum and limbs. It is responsible for driving actions such as acceleration, braking and steering, mainly including core technologies such as chassis by wire.
Driverless technology in China started in 1992 and has been developed for 30 years. At present, the penetration rate and commercialization pace of unmanned driving in China are accelerating. The scale production of l2+ level autonomous driving is soaring and gradually transitioning to L3 level. At the same time, the commercialized application of advanced autonomous driving is gradually expanding in specific occasions. At the technical level, China's driverless technology has its own core technologies at all levels of perception, decision-making and implementation, including Baidu, Alibaba and other technology enterprises. At the application level, the application scenarios of driverless technology in China are very rich. In 2021, driverless commercialization will be applied in many production and living scenarios, including the "last mile" terminal distribution of logistics distribution, the unmanned transportation applied in closed environments such as ports and mines, the unmanned trucks applied in trunk logistics, and the unmanned sanitation vehicles applied to fixed roads in communities. At the supporting level, China has provided more policy and financial support for the technological development in the field of unmanned driving, and the supporting infrastructure and services in each field of unmanned driving technology are becoming more and more complete.
At present, improving stability and reliability is an important direction of unmanned driving technology. This requires that the perception level must be more accurate, the decision-making level must improve the algorithm ability of machine learning and route planning under special circumstances, and the implementation level must improve the effectiveness, security and response speed. In addition, driverless driving puts forward higher requirements for a series of supporting technologies and industries, such as high-power chips, sensors, vehicle manufacturing, artificial intelligence algorithms, vehicle road collaboration, etc. Driverless technology to achieve a breakthrough in bottleneck leapfrog development is closely related to the scientific and technological progress of related industries.
In the past two years, the field of unmanned driving has developed very rapidly in China. At present, the mine unmanned transportation technology has been put into operation, and the research and development of high computing power chips has also made rapid progress. China has an economic structure covering the whole industrial chain, a wealth of driverless application scenarios, the policy and infrastructure support provided by the state, a large amount of funds pouring into the driverless industry, and scientific research institutes vigorously cultivating corresponding talents, all of which provide great advantages for the development of China's driverless industry.
The development of driverless technology will bring about a disruptive change to the automobile manufacturing industry and a boost to the upgrading of modern industry. At present, intelligent assisted driving has become the mainstream of the transformation and development of the automotive industry. In the future, driverless technology will drive the R & D and application of information technologies such as artificial intelligence, Internet of things, big data and cloud computing, and promote China's economic transformation and upgrading. Based on the current technological breakthrough and application trend in the whole driverless industry chain in China, it can be predicted that China will make rapid progress in the industrialization of intelligent assisted driving.
