摘要
侧翻预警是防止运输车辆发生事故的主要手段。基于车辆侧倾角和侧向加速度的监测,建立车辆动态侧翻模型,设计侧翻事故线性判别函数,提出了直接根据侧倾角信号和侧向加速度信号对侧翻事故进行判断的预警算法。通过对某车型进行仿真试验验证了预警算法的有效性,同时本算法具有计算量小、计算速度快等优点,对减少同类交通事故的发生具有重要意义。
Rollover warning is primary means of preventing the transport vehicles accidents.Based on monitoring of rollover angle and lateral acceleration,a vehicle dynamic rollover model is established,linear discriminant function is designed.Rollover accident forewarning algorithm can be put forward,it can judge rollover accidents directly according to rollover angle and lateral acceleration.Effectiveness of rollover forewarning algorithm is verified by a simulation,and the algorithm has less computation,computing speed,etc.,it is very significant to reduce the occurrence of similar accidents.
