摘要

为了使汽车在爆胎后能继续维持爆胎前的行驶状态,对其稳定性控制做了一些研究工作.首先,建立轮胎模型,汽车二自由度理想模型、七自由度实际模型.其次,将FPID运用在爆胎汽车的稳定性控制上,以两模型的横摆角速度偏差(E)及偏差变化率(EC)作为FPID控制器的输入,决策出用以维持爆胎汽车的稳定性的最优附加横摆力矩.最后对所提的FPID控制进行仿真验证.结果表明:FPID控制可以降低爆胎汽车横摆角速度的变化幅度,保证了高速行驶中爆胎车辆的稳定性.

Abstract

In order to keep the Vehicle running after the tire burst,some research on its stability control has been done.Firstly,es-tablishing some models such as the tire model,the ideal 2DOF model of the car and the actual 7DOF model.Secondly,Applying FPID to the stability control of a punctured car.The E and EC are inputed to the FPID controller.The optimal additional yaw mo-ment that can maintain the stability of the car is decided by the differential control.Finally,the proposed FPID control is simu-lated and verified.The results show that:FPID control can reduce the change range of the yaw rate and ensure the stability of a punctured car that running at high speed.
