新型汽车主动避撞安全距离模型

针对现有模型的不足，以驾驶员车间距保持目的假设为基础建立了一种新型汽车主动避撞安全距离模型，通过驾驶员试验获得了反映驾驶员驾驶特点的模型参数。经仿真及试验对比，该模型计算结果体现了驾驶员的驾驶特点，能够适用于多种交通状况，满足了汽车主动避撞系统的要求。

A New Safety Distance Model for Vehicle Collision Avoidance

In view of the drawbacks of existing models, a modified safety dista nce model for vehicle collision avoidance is proposed, based on the assumption o f drivers intent of distance keeping maneuver in actual traffic situation. The model parameters are determined by the experiments on many skilled drivers oper ation. The results show that the proposed model fairly well represents the drivi ng characteristics of drivers and can be applied to different kinds of traffic s ituations and meet the requirements of automotive active collision avoidance sys tem.
