摘　　要：驱动防滑控制系统ASR(Anti-slip Regulation)与坡道起步辅助系统HAC(Hill-startAssist Control)的集成化系统能降低对驾驶员的操纵技术的要求和驾驶疲劳强度,满足人们对汽车乘坐舒适性,操纵方便性和主动安全性的要求。在Matlab/Simulink及德国车辆动力学仿真软件CarMaker建立的虚拟车辆仿真环境下,针对ASR/HAC集成化系统进行了软件在环仿真研究。提出了基于模型参考自适应PID控制的ASR算法和HAC算法,并采用CarMaker和Simulink联合仿真的方式对ASR/HAC系统进行了验证。仿真结果显示汽车的加速性和可操控性明显提高。Anti-slip regulation （ASR） systems can maintain the slip rate within a certain range when a vehicle accelerates on low adhesive road surfaces and thus prevent the drive wheels from rotating uncontrollably. Hill-start assist control （HAC） systems, the latest active safety device, can help avoid sliding backwards, especially when a vehicle starts on a slope. The integration of ASR and HAC systems garners merit from sides-stronger acceleration capacity, increased steerability and easier handling. We develope a virtual vehicle environment on the CarMaker and Matlab/Simulink platforms and used it to test the efficacy of an ASR/HAC system. Based on the Model Reference Adaptive PID（proportional integral derivative） Control, new ASR and HAC system algorithms also are introduced and integrated as one. The simulation results show that the vehicle acceleration and control characteristics are enhanced.
