The invention discloses a vehicle following model stability control method considering driver perception error, which is used for solving the influence of the driver random perception error on the traffic flow stability. According to the method, under the condition of considering that a driver has an information perception error for the motion state of a preceding vehicle in the vehicle followingprocess, vehicle head distance and preceding vehicle speed confidence level parameters are introduced, a vehicle following model considering the driver perception error is established, and on the basis, a feedback control method is designed to enhance the stability of the model. Compared with a model which does not consider a feedback control method, the provided feedback control method can effectively improve the stability of the queue, and technical support is provided for queue stability control methods in the fields of traffic management and control, vehicle intelligent control and the like.
本发明公开了一种考虑驾驶人感知误差的车辆跟驰模型稳定性控制方法,用于解决驾驶人随机感知误差对交通流稳定性的影响。本发明是在考虑驾驶人在跟车过程中对前车运动状态存在信息感知误差的情况下,引入车头间距与前车车速置信水平参数,建立一种考虑驾驶人感知误差的车辆跟驰模型,并在此基础上,设计了一种反馈控制方法来增强模型的稳定性。对比未考虑反馈控制方法的模型,提出的反馈控制方法能有效的提高队列的稳定性,为交通管理与控制和车辆智能控制等领域的队列稳定性控制方法提供技术支持。
