基于TTR和LTR的轻型客车侧翻预警及仿真

摘要

Untripped rollover mechanism of a light bus is analyzed in this paper,and a vehicle rollover prediction method based on TTR and LTR is proposed,and co-simulation model is built in TruckSim and Simulink,that is used to simulate the rollover behavior of light bus in fishhook conditions.The simulation results show that the built rollover warning system can warn the light bus in a timely manner,and it can provide the most reliable warning when TTR=0.4 in fishhook conditions.%针对某轻型客车的非绊倒性侧翻机理进行了分析,提出了基于TTR和LTR的车辆侧翻预测方法,并建立了TruckSim和Simulink的联合仿真模型,利用该模型对轻型客车在鱼钩工况下的侧翻性能进行了仿真.仿真结果表明,所建立的侧翻预警系统能适时地对轻型客车进行侧翻预警,且在鱼钩工况下TTR=0.4时的预警最可靠.
