摘要
为更加真实地反映爆胎车辆的运动状态,考虑爆胎工况下驾驶员行为对汽车的影响,在主动制动控制策略下,对爆胎汽车进行驾驶补偿控制。根据轮胎力学参数的变化,在轮胎模型基础上构建爆胎模型,结合车辆动力学方程建立爆胎车辆动力学模型,以主动差动制动的方式对爆胎汽车进行稳定性控制,通过驾驶员模型来模拟爆胎工况下司机对方向盘转角控制,分析动力学响应并设计驾驶转角补偿器来修正驾驶员操作引起的汽车失稳状态。结果表明,爆胎会使车辆的运行状态发生改变,驾驶员的行为会导致车辆严重失稳与偏航,差动制动和转角补偿控制可以平衡爆胎过程中产生的不稳定因素并修正驾驶员操作带来的影响,使车辆保持稳定并沿预期轨迹减速行驶。
In order to more truly reflect the motion state of the vehicle with a flat tire,considering the impact of driver behavior on the vehicle under the working condition of a flat tire,under the active braking control strategy,the vehicle with a flat tire is subject to driving compensation control.According to the changes of tire mechanical parameters,a tire burst model was built on the basis of tire model,and a tire burst vehicle dynamic model was constructed based on vehicle dynamics equations.The stability of the tire burst vehicle was controlled by active differential braking.The driver’s control of steering wheel angle under the condition of tire burst was simulated through the driver’s model,and the dynamic response was analyzed and the driving angle compensator was designed to correct the vehicle’s instability state caused by the driver’s operation.The results show that the running state of the vehicle will change greatly when the tire blows during driving,and the driver’s behavior will cause serious instability and even yaw.The differential braking and angle compensation control can balance the unstable factors during the tire blowing process and correct the impact of the driver’s operation,so that the vehicle can keep stable and decelerate along the expected trajectory.
