摘要
运用综合加权的方法分析了驾驶员个体因素对安全车距模型参数的影响,提出了基于修正因子的考虑驾驶员个体特性差异的避撞系统安全车距修正模型。通过不同行驶工况下的仿真验证了提出的安全车距修正模型对不同驾驶员个体状态的适应性。分析说明了驾驶员个体特性的差异主要影响报警安全车距,对极限安全车距的影响较小。
The influence on safety distance model from the driver states was analyzed by using compositive weighting method,and a modified model based on modification factor was proposed to take consideration the effects of driver characteristics.Simulations have been done for car following and collision warning in different driving situations,which demonstrates the flexibility of the new algorithm of vehicle safety distance.And the conclusion is also obtained that the effect of the driver individual characteristics are mainly focused on the warning safety distance,and little on critical safety distance.
