摘　　要：针对在量产车基础上增加执行机构改装成的具有自主驾驶功能的智能汽车,提出执行机构的功能要求,并为各辅助操控机构设计了一整套解决方案。采用Micro Auto Box作为执行控制器,以实现执行机构的集成。针对制动系统的强非线性,提出了基于压力外环的主缸压力控制策略。基于Lab Windows开发了智能车远程监控界面。实验结果表明,所设计的执行机构精度较高、响应较快、功能全面,能较好地满足智能汽车实验要求。The functional requirements of actuators are proposed for an intelligent vehicle with autonomous driving function retrofitted by adding actuators on a mass-produced vehicle,and a complete set of solving scheme for all auxiliary handling mechanisms is designed. Micro Auto Box is used as actuator controller to fulfill the integration of actuators. In view of the strong nonlinearity of brake system,a control strategy for master cylinder pressure is put forward based on pressured outer ring,and a remote monitoring interface for intelligent vehicle is developed based on Lab Windows. The results of experiments show that the actuators designed have higher accuracy,quicker response and all-around functions and can better meet the requirements of intelligent vehicle experiments.
