摘　　要：当前实际应用中的车辆纵向自动跟随方法 ACC(自适应巡航)在应对小间距或速度频繁变化时,后车响应速度及队列跟随整体性不够理想。针对此类问题,充分考虑实际路况中车辆加速和制动性能的差异,研究一种通过V2V(车-车)通信接收动力输出差异信息的协同式纵向队列跟随控制方法,并结合车辆最小安全间距对实施过程进行了分析。最后对4辆不同车辆组成的纵向队列在Matlab/Simulink中进行仿真。实验结果表明,这里方法在车辆纵向队列行驶及间距调节过程中的车辆最大速度差及加速度绝对值较小,队列整体性较强。The speed response and stability of vehicle platooning is not ideal when ACC（Adaptive Cruise Control） is applied to the vehicle-following control that has small spacing and frequent changes.Taking into account the current problems, this paper presents the control strategy for vehicle platooning relying on V2V（vehicle-to-vehicle）communication and performance rating based on CACC （Cooperative Adaptive Cruise Control）, the control process is analyzed in combination with the minimum safety spacing. Finally,the simulation of 4 different vehicles is carried out in Matlab/Simulink. The experimental results show that the maximum speed error and absolute maximum acceleration is smaller than before, and the stability of the platoon is better.
