摘　　要：首先建立了八自由度的汽车动力学模型,设计了模糊PI控制器和汽车稳定性控制策略。建立了基于Matlab/Simulink平台下的硬件在环试验平台,针对转向制动和双移线转向行驶两种工况进行了硬件在环仿真试验。结果表明:所设计的模糊PI控制器及控制策略可以通过制动力控制有效地抑制汽车的过多转向或不足转向趋势,提高汽车的操纵稳定性。An 8-DoF vehicle dynamics model was established and a fuzzy PI controller and a control strategy of a vehicle stability control system were developed. A hardware-in-loop simulator was built based on Matlab/Simulink platform, and the hardware-in-loop simulations were performed for the cases of the vehicle steering brake and double-lane steering. The results show that the fuzzy PI controller and the control strategy suppress the vehicle oversteering or understeering by the effective control of the brake force and the vehicle control stability is improved significantly.
