摘要
针对汽车巡航智能控制问题,基于模糊理论提出了节气门与刹车综合调控的智能控制策略。建立了安全跟随距离与相对速度的双输入单输出模糊控制器,结合某轿车实车数据,采用Simulink设计了巡航系统智能控制仿真模块,针对城市道路典型运行工况实施了仿真验证。结果表明:该策略具备自动起步与停车及智能跟随前车且保持安全车距等集成控制功能,可有效提高汽车行驶的主动安全性,其研究成果可为系统dSPACE原型搭建及开发提供必要的理论参考。
An intelligent control strategy is put forward based on the throttle and braking combined control for automobile cruise system adopting the fuzzy control theory.A fuzzy logic controller is presented,which consists of two input variables and one output variable on the safety following distance and relative velocity.Combining with car data,the simulation module on the intelligent cruise control system is designed adopting Matlab/Simulink,and the varying of the typical traffic running cases is validated through simulation.The simulation results show that the control strategy possesses integrated capability of automated stop go control,and following the preceding car keeping the safety distance,and increases automobile active safety.The research result can offer the theory reference for setting dSPACE type and the product development of cruise system.
