Based on the two different evaluation methods of desensitization effect of video images outside the car proposed in the association standard"Technical Requirements and Methods of Desensitization of video and image in Vehicle Transmission"(T/CAAMTB 77-2022)and"Practice Guide of Network Security Standards-Verification of the effect of Local contour Processing of the exterior Picture"(draft for comment),the capability was built and the actual application test was carried out respectively.The paper compares and analyzes the advantages and disadvantages of the two methods in the implementation process and evaluation effect through specific cases and hopes to promote the exploration and research of the test methods,so as to further ensure the safety and compliance of data return at the end of intelligent connected vehicles.

虚拟仿真是智能网联汽车研发和测试的重要一环,仿真场景的数量多少和质量高低决定了 自动驾驶策略的优劣.汽车产业有很多生成虚拟仿真场景的方法.本文依据《智能网联汽车数据格式与定义》(T/CAAMTB 34-2021)团体标准进行了一种低成本、以数据驱动自动化生成场景的技术链路打通.该方案首先对自然驾驶中危险工况场景数据进行采集,并对其进行分析处理,依据标准生成结构化数据.该结构化数据可以批量自动化生成符合国际通用格式的OPEN X系列标准的仿真场景,为后续大规模数据驱动测试场景自动化生成奠定了基础.

伴随着汽车智能化、网联化发展,智能网联汽车会产生诸如未经授权的个人信息、重要数据采集和利用等数据安全问题,智能网联汽车数据安全监管和检测需要加强.为此,本文对基于4G和5G无线通信模拟基站CMW500的汽车无线通信传输数据安全测试的方法展开研究.
