摘　　要：为了预防他车突然夹塞变道斜插入自车与前车之间间隙的危险驾驶行为,提出了加速跟车的车辆控制策略.在跟车安全距离模型的基础上,考虑车头时距、停车间距等跟车特性,建立基于3种类型驾驶员的跟车安全距离模型和防夹塞安全距离模型.通过Sigmoid函数建立了基于变安全距离控制策略的车速控制器,检测到他车夹塞变道,选择防夹塞安全距离模型;无夹塞车辆时,选择跟车安全距离模型.利用MATLAB/Simulink和CarSim联合仿真平台进行了试验,结果表明基于3种类型驾驶员变安全距离防夹塞变道的车辆控制策略可行.To prevent the dangerous driving behavior of cut-ins inserting into the gap between the ego car and the lead car,a vehicle control strategy for accelerating was proposed.According to the following safety distance model,considering the following characteristics of time headway and parking distance,a following safety distance model and an anti-cut-ins safety distance model were established based on three types of driver.A vehicle speed controller based on the variable safety distance control strategy was established by the Sigmoid function.When another vehicle was detected to cut-in,the anti-cut-ins safety distance model was selected,otherwise the following safety distance model was selected.The MATLAB/Simulink and CarSim co-simulation platform was used to carry out experiments.The results show that the vehicle control strategy based on three types of driver′s variable safety distance and anti-cut-ins is feasible.
