Recently, the international standard "Road Vehicle auto drive system Test Scenario Evaluation and Test Case Generation" (ISO 34505), which was led by China, was officially released. The standards released this time mainly stipulate the evaluation process and test methods of auto drive system test scenarios, define the judgment requirements of the evaluation indicators such as exposure rate, complexity and danger of test scenarios, and define the general methods and necessary features of test case generation. The global technical regulation coordination and international standard setting projects led and participated in by China's automotive industry have reached as many as 50. ”Sun Hang, Chief Engineer of China Automotive Standardization Research Institute of China Automotive Technology Research Center Co., Ltd., the leading developer of this international standard, said in an interview with reporters, "This international standard was led and successfully released by China, due to the good foundation laid by China's automotive industry in the early stage of international standardization work, as well as China's first mover advantage in the establishment of the autonomous driving industry." Sun Hang explained that autonomous driving test scenarios can present the occurrence environment and process of traffic scenarios in the real world. The scenario based testing method is a method of testing a vehicle by requiring it to achieve specific goals through pre-set testing scenarios. In the development and validation, testing and evaluation, as well as detection and certification stages of autonomous driving functions, scenario testing is required to meet specific tasks. The function and performance of autonomous vehicle are mainly evaluated through a series of scenario based tests. In the development stage of autonomous driving functions, it is necessary to verify the performance of the functions in specific applications. Various scenario tests based on the application scope are an important means of verifying the effectiveness of autonomous driving functions, which can support developers to adjust and improve the functions; After completing the development of autonomous driving functions, further testing and evaluation are needed. By constructing scenarios that reflect specific vehicle performance and developing reasonable testing tasks, it is possible to evaluate the performance of autonomous driving functions in different dimensions, such as safety, economy, comfort, etc; Before the vehicle is officially on the road, it needs to be tested and certified. By building a typical test scenario, you can examine the behavior of the auto drive system in various traffic situations, and prove its safety and reliability in the real traffic environment. The relevant person in charge of the First Equipment Industry Division of the Ministry of Industry and Information Technology introduced that the release and implementation of this standard reflected the important consensus reached by the automated driving test verification technology worldwide, helped to form a complete set of scenario application frameworks from conceptual design to modeling and simulation, from the construction of scenario library to the construction of actual test sites, provided basic standards for the simulation development and test evaluation of the auto drive system, and effectively met the urgent needs of auto drive system safety assessment and test verification. In recent years, China has entered the fast lane of development in the field of autonomous driving: technological breakthroughs continue to be made, and domestic automotive companies have continuously iterated and accumulated a large amount of practical experience in the research and development of complete vehicles and key system components, end-to-end software architecture, and basic scenario library construction; Multiple application scenarios have blossomed, and some areas of cities such as Beijing, Shanghai, and Shenzhen have achieved commercial operations in shared travel, regional connections, express delivery, and specialized logistics, promoting China to become a core battlefield for exploring the commercialization of autonomous driving worldwide; The standard system is accelerating its improvement. China has established an autonomous driving standard system that covers basic, functional specification, test method, and critical system categories, and has taken the lead in proposing the development of autonomous driving test scenarios and a series of technical standards for core perception components of autonomous driving internationally. Sun Hang introduced that in addition to promoting the development of scene series standards, China has also led the preparation of more than 10 international standards in the field of autonomous driving, including functional safety, electromagnetic compatibility, laser/millimeter wave radar, testing equipment, etc., within the scope of the International Organization for Standardization. In addition, within the scope of the United Nations World Forum for Harmonization of Vehicle Regulations, China has also taken the lead in formulating important technical regulations on the safety of auto drive system, which will provide unified specifications for the safety deployment of global auto drive system. The Ministry of Industry and Information Technology stated that the next step will be to organize units such as China Automotive Technology Research Center Co., Ltd. to deeply participate in the revision of international standards in the automotive field, and continuously enhance China's participation and contribution in the coordination of international automotive standards and regulations.
