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。
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.
