摘　　要：提出了一种基于TTR的汽车侧翻预警算法。建立了3自由度线性汽车侧翻模型,推导了基于汽车侧倾角度变化的TTR侧翻预警计算公式,提出了TTR侧翻预警算法。以某轻型卡车为研究对象进行了汽车侧翻过程中侧倾角变化的仿真分析,获得了TTR侧翻预警算法的汽车侧翻预警时间。仿真结果表明:该侧翻预警算法能准确地对汽车侧翻时间进行预测,从而为汽车侧翻预警控制器开发提供理论依据。In this paper,a vehicle rollover warning algorithm is proposed.First,a three-DOF linear model of vehicle rollover is established.From the model,the rollover warning algorithm is proposed based on time to rollover （TTR）.Also,the TTR value is obtained from the variation of vehicle roll-over angel.Then the simulation is conducted for a light truck.And the results show that the rollover warning algorithm can accurately predict the time to rollover,thus providing a theoretical basis for the development of vehicle rollover warning controller.
