Abstract: The velocity of the vehicle on the road is non-constant,and the velocity of the following vehicle changes also.The driving behavior is difficult to be accurately described with mathematical model for the uncertainty behavior characteristics displayed in the driving process.This paper proposes a safe distance control algorithm of car-following based on two-dimension cloud model,and the algorithm is tested by simulation of anxious acceleration/deceleration in car-following process under the impact of unexpected events.

Key words: driving behavior, safe distance, vehicle-following, two-dimension cloud control

摘要: 车辆行驶在道路上时速度并非恒定的,于是跟随其行驶的车辆也会随着前车变化而变化。然而,在驾驶过程中驾驶员表现出的不确定性行为特征,使得人们对驾驶员的行为难以进行精确的数学描述。基于安全距离理论提出了跟车二维云控制算法,并对驾驶行程中由于突发事件的影响,驾驶员急加减速的跟车行为进行仿真。
