高速公路超长爬坡路段重载车辆行驶状态安全稳定性分析研究

准确分析重载车辆在高速公路超长爬坡路段的行驶状态,能够保证车辆的主动安全控制,当前车辆形式状态安全稳定性分析大多采用单一集中卡尔曼滤波方法,存在容错性差的弊端,稳定性和可靠性不高。为此,从新的角度对高速公路超长爬坡路段重载车辆行驶状态安全稳定性进行分析,通过失稳角对行驶状态安全稳定性进行分析,依据弯道路段事故特征分析重载车辆出现侧翻与侧滑的现象,得出高速公路路面情况、坡度和转弯半径对重载车辆行驶状态安全稳定性有影响的结论。引入加速度干扰概念,以更加有效的分析重载车辆行驶安全稳定性。实验结果表明,所提方法能准确分析重载车辆行驶状态的安全稳定性。

State highway long uphill road overload vehicle safety stability analysis research

the accurate analysis of overloading vehicles in highway long uphill road condition, can ensure the vehicle active safety control, the current state of vehicle form most security stability analysis using a single centralized kalman filtering method, disadvantages of poor fault-tolerance, stability and reliability is not high.Therefore, from the Angle of new highway long uphill road overload vehicle state security stability analysis, through buckling Angle of driving state security stability is analyzed, based on the curve characteristics of road accident analysis and overload vehicle rollover and sideslip phenomenon, it is concluded that the highway pavement condition, slope and turning radius of overloading vehicles driving stability conclusions about the effects of state security.Introducing concept of acceleration interference, in order to more effective stability analysis of overloading vehicles driving safety.Experimental results show that the proposed method can accurately analyze overload safety stability of the vehicle state.
