摘要
针对大客车在山区公路危险工况下不能兼顾防侧翻控制与路径偏离控制的问题,文章提出了一种大客车防侧翻及路径偏离恢复协调控制策略。利用防侧翻及路径偏离恢复临界值权重控制方法,对大客车在危险工况下侧翻危险系数及偏离车道危险系数进行了实时预估,并根据危险系数临界值进行控制方法的权重分析,利用Matlab/Simulink平台建立了多自由度整车模型,对所提出的大客车稳定性控制策略进行了仿真分析。分析结果表明,所提出的方法在一定程度上能实现大客车侧翻稳定性与路径偏离的协调控制,在降低大客车侧翻危险性的同时减少大客车路径偏离程度,有效提高了大客车在山区公路或其他工况下的行驶稳定性。
In order to solve the problem that the motor coach driver can not take into account the control of rollover and lane departure in dangerous mountain road conditions simultaneously, a coordinate control strate- gy of rollover prevention and lane restoration for motor coach is proposed. With the critical value weights con- trol method of rollover prevention and lane restoration, the rollover risk factor and the lane departure risk fac- tor are estimated in real time, and according to the critical value of the risk factor, the control method weights are analyzed. The multi-degree of freedom（DOF） vehicle model is established by using the Matlab/Simulink platform, and the proposed motor coach stability control strategy is simulated. The results show that the pro- posed method can achieve the coordinate control of rollover prevention and lane restoration for motor coach to a certain extent, and can reduce the rollover risk and the degree of deviation of the motor coach from the path, thus effectively improving the motor coach stability in mountain highway or other dangerous conditions.
