摘要
随着自动驾驶技术的快速发展,潜在的安全风险不断增加并日益突出。通过分析自动驾驶车辆可能出现的安全问题,提出了预期功能安全(SOTIF)的概念,并对比其与功能安全及信息安全技术的差异,定义了实现预期功能安全的技术路线。由功能定义出发,通过危害分析和风险评估、验证已知案例和未知案例,找出自动驾驶车辆可能存在的安全功能不足并进行功能改进,最终,通过整车集成、测试、验证和确认,从而确保自动驾驶车辆达到合理的功能安全技术水平。所形成的研究成果作为中国提案,为正在制定的国际标准(道路车辆预期功能安全)提供了参考借鉴。
With the occurrence of automatic driving technology, potential safety risk is rising. The concept of safety of the intended functionality （SOTIF） is given based on analyzing the safety issues related with automatic driving, and the differences among SOTIF, Functional Safety and Security technology are compared, then technical routine of SOTIF is defined. Starting from function definition, the paper finds out the weakness of autonomous driving vehicle and improving the functionality by hazard analysis, risk evaluation and verifying the known and unknown cases, in order to make the autonomous driving vehicle to achieve a reasonable level of safety.
