摘　　要：文章设计了基于滑膜变结构控制的车距智能保持系统,通过对系统架构的模块化拆分,将车距保持系统分为上层滑膜控制系统和下层前馈-反馈控制系统进行分别开发。通过在Carsim~?中搭建实车仿真环境,并与Simulink联合仿真,验证了全速自适应车距保持系统控制律,仿真结果表明滑膜控制算法可以在多种工况下稳定并且准确地实现驾驶员的跟踪目标。In this paper, the vehicle distance intelligent maintenance system is designed. Through the modular separation, the distance maintenance system is divided into upper synovial control system and lower feed - forward feedback control system, which are developed respectively. By building a real car simulation environment in Carsim＇s and co -simulation with Simulink, the full speed adaptive distance keeping system control rule designed in this paper is verified. The simulation results show that the synovial control algorithm can stably and accurately achieve the driver＇s tracking objec- tives under a variety of operating conditions.
