| 摘 要： | 文章首先利用模糊法则建立能够反映驾驶员反应时间的隶属度函数,并根据制动过程理论建立安全距离模型,通过安全距离模型建立期望加速度模型。然后分别建立加速和制动模型,在此基础上制定控制模式转换策略,基于PID算法设计巡航控制器。最后在Matlab/Simulink和CarSim联合仿真环境中验证所设计的控制系统的有效性。

| Abstract: | The membership function that can reflect the driver’s reaction time is firstly established by using the fuzzy rule,and the safety distance model is established according to the braking process theory,and the expected acceleration model is established through the safety distance model in this paper.Then the acceleration model and the braking model are established respectively,based on which the control mode conversion strategy is formulated,and the cruise controller is designed based on PID algorithm.Finally,the effectiveness of the designed control system was verified in the Matlab/Simulink and CarSim co-simulation environment. |
