摘要:
自适应巡航控制( ACC )为汽车驾驶提供了便捷性,通过对跟车控制上层控制算法以及下层执行策略进行设计,加强巡航控制功能的跟随性、安全性和舒适性。设计了考虑制动安全距离和舒适加速度的变时距跟车策略,基于滑模变结构控制算法实现跟车功能,建立包含速度偏差与距离偏差的滑模控制面,并改进趋近率缓解系统抖振。基于 Carsim 动力学仿真软件搭建 ACC 自适应巡航仿真车辆与交通环境,通过节气门开度、制动主缸压力作为 Carsim 的输入信号实现对车辆的闭环控制,与 MATLAB / Simulink 实现联合仿真。将使用传统 PID 算法跟车策略的实车实验与改进后的仿真跟车算法对比,结果验证了发动机逆模型和制动器逆模型的合理性,同时,车辆控制的精确性和舒适性都显著提升,跟车距离更具安全性。
Abstract:
The Adaptive Cruise Control( ACC ) brings convenience to driving a car.By designing the upper-level control algorithm as well as the lower-level execution strategy for following control , the following , safety and comfort of the cruise control function are enhanced.A variable time distance following strategy considering braking safety distance and comfortable acceleration is designed , the following function based on sliding mode variable structure control algorithm is realized , a sliding mode control surface including speed deviation and distance deviation is established , and the approach rate mitigation system is improved.The ACC adaptive cruise simulation vehicle and traffic environment are built based on the Carsim dynamics simulation software.The closed-loop control of the vehicle is realized by using the throttle opening and brake master cylinder pressure as the input signals of Carsim , and the joint simulation is realized with Matlab / Simulink.Comparing the real vehicle experiment using the traditional PID algorithm following strategy with the improved simulation following algorithm , the results verify the rationality of the engine inverse model and the brake inverse model.At the same time , the accuracy and comfort of vehicle control are significantly improved , and the following distance is safer.
