Intelligent car technology overlay complex car intelligent collaboration is the core

A new round of scientific and technological revolution and industrial changes are booming. Smart cars have become the strategic direction for the development of the automotive industry. They are also the hotspot of research in the world of vehicle engineering and the new driving force for the growth of the automotive industry. Many developed countries have incorporated them into their own intelligent transportation systems.

At present, the “three-step” strategy development route for the development of smart cars in China has been clear and the goals are exciting. Smart cars have become the only way for China to change from a big car country to a car power. It is also a rare opportunity for China's auto industry to overtake the car and seize the commanding heights of advanced technology!

However, as a comprehensive system integrating environmental awareness, planning decision-making and multi-level assisted driving functions, smart cars, such as computers, sensors, information fusion, communication, artificial intelligence, and automatic driving, must be operated at the same time to achieve the best condition. The complex technology integration has made the development of the global smart car industry still in the early stage of exploration.

Sun Liqing believes that it is equipped with advanced in-vehicle sensors, controllers, actuators, etc.; it combines modern communication and network technology, with the perception of complex environment, intelligent decision-making and automatic control functions; between the vehicle and the external nodes To achieve the sharing of information and control synergy, to achieve zero casualties, zero congestion, to achieve safe, efficient, energy-saving driving of the next generation of cars, can be called smart cars.

At present, the core technologies such as automatic parking technology, adaptive cruise system technology, intelligent interconnection technology, V2X technology and HMI interaction technology have not reached the optimal level. When the technology is mature, the smart car superimposed with these technologies can realize the information sharing and control coordination between the vehicle and the nodes of the external environment, achieving zero casualties, zero congestion, and achieving safe, efficient, and energy-saving driving.

Sun Liqing said that in addition to the complex technology of the car itself, the infrastructure such as roads needs to be intelligent, and the intelligent cooperation of vehicles and roads can promote the development of the smart car industry. Vehicle information acquisition based on wireless communication, sensor detection and other technologies, through vehicle and vehicle information interaction and sharing, and intelligent cooperation and cooperation between vehicles and infrastructure, can optimize the use of system resources, improve road traffic safety, Alleviate the problem of traffic congestion.

In addition to technological innovation, Professor Sun Liqing compared the policies and models of the United States, Japan, Switzerland and China in Beijing, Shanghai, Chongqing and Guiyang. He believes that the industry should be formed. The alliance mode finally realizes the purpose of “use”, that is, comprehensively and comprehensively utilizes intelligent road network, intelligent driving, big data application and high-precision positioning to ensure the automatic driving.

Sun Liqing said that communication technology is the key to smart cars. The current 5G technology is related to the development of smart cars. Large-scale multi-entry is the most important key technology of 5G. The development, optimization, performance evaluation and comparison, and layout optimization of large-scale multi-entry and multi-base stations are also inseparable from supporting large-scale multi-input and multi-channel simulators!

In addition, the car's perception of the environment is especially important! Sun Liqing introduced that the car's environmental perception mainly uses sensor fusion technology to obtain useful information of the vehicle's driving environment, such as traffic information, lane status information, speed information of surrounding vehicles, driving sign information, and so on.

In this way, the automotive environment sensing technology is inseparable from the corresponding sensors. The sensor converts various external signals into identifiable electrical signals, the most important of which is the road perception module, which combines advanced communication technology, information sensing technology, and computer control technology. The environment-aware technology mainly comes from the sensing module, the analysis module, and the control module.

Although the development of smart cars has not yet formed a complete industrial chain, and there are still many difficulties in the process of development, in the process, it is constantly gathering with the "government, industry, research and research" Together, discuss and discuss together, the collision of thinking can produce a spark of inspiration, the autopilot industry can continue to break through the technical bottleneck, usher in the era of smart cars!
