【摘要】：为了探索协同自适应巡航控制(cooperative adaptive cruise control,CACC)车辆对交通系统的潜在影响,分析了CACC车辆市场普及过程中存在的CACC车辆、自适应巡航控制(adaptive cruise control,ACC)车辆与人工驾驶车辆混合交通流驾驶舒适性.应用加州伯克利PATH实车验证的ACC模型和CACC模型进行数值仿真实验,采用国际ISO-2631-1标准评价混合交通流舒适性,并对ACC和CACC期望车间时距进行参数敏感性分析.最后,从交通流稳定性的角度,对舒适性仿真结果进行了讨论.结果表明:随着CACC市场率的增加,舒适性呈现先恶化、再逐渐提升的趋势.较大的ACC车间时距有利于抑制舒适性的恶化程度,CACC车辆对舒适性的提升作用不受其车间时距取值的影响.混合交通流稳定性定性地决定了舒适性的变化趋势,人工车辆安装车车通信设备,有助于舒适性的逐渐提升.
[Abstract]:In order to explore the potential impact of cooperative adaptive cruise control (adaptive cruise control) vehicles on traffic system, this paper analyzes the existence of CACC vehicles in the process of the popularization of CACC vehicle market. Adaptive Cruise Control (cruise Control ACC-AC) vehicle and manual driving vehicle mixed traffic flow driving comfort. The ACC model and CACC model verified by PATH in Berkeley, Calif., are used to carry out the numerical simulation experiment, and the international ISO-2631-1 standard is used to evaluate the comfort of mixed traffic flow. The parameter sensitivity analysis of the expected workshop time interval between ACC and CACC is carried out. Finally, the simulation results of comfort are discussed from the point of view of traffic flow stability. The results show that with the increase of market rate of CACC, the comfortableness becomes worse first and then increases gradually. The larger time distance of ACC workshop is helpful to restrain the deterioration of comfort and the lifting effect of ACC vehicle to comfort is not affected by the value of workshop time distance. The stability of mixed traffic flow determines the changing trend of comfort qualitatively. The installation of vehicle-vehicle communication equipment by artificial vehicles is helpful to the gradual improvement of comfort.
