A Rollover Warning Algorithm for Improving Steering Wheel Angle TTR and Dynamic Mass Centroid Height

  • 摘要: 为了消除传统Time to Rollover侧翻预警算法中,方向盘与汽车动态响应之间的滞后性以及质心高度变化对算法精度的影响,本文中提出了方向盘转角TTR和动态质心高度预警算法。建立三自由度的动态模型,用Maple求解出方向盘转角与各个运动参量的关系,接着将数学模型导入动力学软件TruckSim中,在数个典型工况下进行仿真实验。对比传统算法的运动参量和改进算法的TTR,并将仿真的质心高度和理论算法计算结果比较。仿真实验结果表明,动态模型计算结果准确,改进后的侧翻预警算法提前于传统算法,有效改善了TTR算法的滞后问题,提前了预警时间,研究成果具有工程应用前景。
