【摘要】 本文在分析悬架对操纵稳定性影响的基础上,提出了一种半主动悬架控制算法,用于提高车辆在极限工况下的操纵稳定性。采用matlab/simulink建立了十五自由度车辆动力学模型和控制器模型并进行了计算机仿真。仿真结果表明,本文提出的半主动悬架控制算法能够有效防止车辆在非稳态工况下失稳和抑制车辆侧倾,提高了车辆的操纵稳定性和驾驶舒适性。更多还原

【Abstract】 In this paper,a semi-active suspension control algorithm is proposed to enhance the handling stabilaty of the vehicle in extreme working conditions,on the the analysis of the impact of the suspension on the handling stability.The 15 degrees of freedom vehicle dynamics model and the controller model is built and a simulation is carried out in matlab/simulink environment.The simulation results show that a semi-active suspension control algorithm can effectively prevent the vehicle instability in non-steady state conditions,and inhibition of vehicle roll and can improve the handling stability of the vehicle and driving comfort.更多还原
