The invention discloses an expected function safety optimization method for performance limitation of an automatic driving decision-making system, and the method comprises the steps: building a decision-making system control structure, and defining the level loss of a whole vehicle system; constructing a decision system limitation simulation dangerous scene, and performing a decision system limitation virtual simulation test; judging whether the whole vehicle system level loss exists in the simulation test result or not, if the whole vehicle system level loss exists, analyzing an unsafe control behavior and a reason for generating the unsafe control behavior according to the simulation test whole vehicle performance so as to correspondingly carry out function improvement on the decision-making system, and repeating the steps; and if the whole vehicle system level loss does not exist, judging that the limitation of the decision-making system meets the function requirement. According to the expected function safety optimization method provided by the invention, the safety of the automatic driving decision-making system is improved, and the safety of the whole vehicle is greatly ensured.

    本发明公开了一种自动驾驶决策系统性能局限的预期功能安全优化方法,包括建立决策系统控制结构,定义整车系统级别损失;构建决策系统局限性仿真危险场景,进行决策系统局限性虚拟仿真测试;判断仿真测试结果是否存在整车系统级别损失,若存在整车系统级别损失,则根据仿真测试整车表现分析不安全控制行为和不安全控制行为产生的原因,以相应对该决策系统进行功能改进,重复步骤;若不存在整车系统级别损失,则判定该决策系统局限性满足功能需求。本发明提供的预期功能安全优化方法提高了自动驾驶决策系统的安全性,极大地确保整车安全。
