基于优化计算的驾驶员模型及其在功能安全设计中的应用

Driver Model and Its Application in Functional Safety Design Based on Optimization Calculation

设计了一种可兼顾不同驾驶水平的新型驾驶员模型,能够通过调节应用参数对不同驾驶员的整体表现进行仿真,最终评定某电控功能失效后的影响及功能安全等级。以双移线变道行驶场景为基础,应用设计的驾驶员模型进行了制动能量回收功能失效条件下的典型工况仿真,得到了制动能量回收功能的功能安全等级与故障容忍时间。

A novel driver model which can imitate different driving skills is designed, which can simulate overall performance of different drivers through adjustment of application parameters, finally the effect of an electric-control function and function safety grade after eletric-control function fails. Based on the double lane change driving scenario, the designed driver model is simulated in typical condition under condition that braking energy recovery fails, the function safety grade and failure tolerance time of braking energy recovery function are obtained.
