摘要
现有的AEB系统在驾驶员介入后,无论驾驶员操作是否正确,系统都会自动取消介入。为了优化这一性能,文章根据所设计的有驾驶员介入的自动紧急制动系统算法流程图,基于临界安全距离模型,利用PID控制方法在Simulink中建立车辆自动紧急制动模型,并与Carsim整车模型进行联合仿真。通过仿真验证了所设计算法及自动紧急制动模型的合理性,从一定程度上对现有AEB系统进行了优化。
The existing AEB system automatically cancels the intervention of the system after the driver intervention,regardless of whether the driver is operating correctly.in order to optimize this performance,According to the designed algorithm of automatic emergency braking system with driver intervention,based on the critical safety distance model,the vehicle automatic emergency braking model is established in Simulink by PID control method,and co-simulation with Carsim vehicle model.The rationality of the designed algorithm and the automatic emergency braking model is verified by simulation,and the existing AEB system is optimized to some extent.
