用于爆胎车辆仿真的驾驶员模型

分析了驾驶员模型在汽车爆胎仿真应用中存在的问题及爆胎后车辆响应特性的变化,指出爆胎后车辆响应特性发生改变是导致驾驶员模型不能控制爆胎后汽车回到原路径的根本原因。建立了考虑爆胎后车辆左、右转向特性不对称的驾驶员模型,并进行了仿真。最后在原驾驶员模型中加入状态参考器,并对不同车速下的状态参考器参数进行辨识。解决了驾驶员模型在汽车爆胎仿真中的应用问题,为进一步研究汽车爆胎后驾驶员的操作规律及爆胎后汽车的稳定性控制提供了参考。

Driver model used in vehicle tire blow-out simulation

The problem of application of the driver model in the vehicle tire blow-out simulation and the changes of the vehicle response behavior after the tire blow-out were analyzed,and it was found that vehicle response changes after the tire blow-out are the main cause leading to the problem that the driver model can not drive the vehicle back to the original trajectory.A new driver model considering the fact that the vehicle is characterized by unsymmetric leftward and rightward turning after the tire blow-out was built and its simulation was performed.A vehicle state reference module was embedded in the original driver model and its parameters were identified under different driving speeds.Thus the problem of application of the driver model in the vehicle tire blow-out was solved,providing a reference for the study of driver operation behavior and stability control of the vehicle after tire blow-out.
