The invention relates to a layered vehicle queue economical driving cooperative control method. The method comprises the following steps that S1, a vehicle queue composed of pure electric vehicles is constructed; s2, constructing an upper-layer control strategy, and planning an economical vehicle speed track for the pilot vehicle; s3, constructing a lower-layer control strategy; s4, transmitting the economic optimal torque sequence of the pilot vehicle obtained in the step S2, the current most economic vehicle speed and the current state information of the pilot vehicle obtained in the step 3 to each following vehicle through vehicle-to-vehicle communication V2V; and S5, receiving the information transmitted in the step S4 through the lower-layer vehicle following control strategy in the step S3, and carrying out optimization control on the queue following vehicles, thereby completing cooperative control on the economical driving of the layered vehicle queue. According to the hierarchical optimization control strategy designed by the invention, the economic driving technology and the queue cooperative control technology are fused, the overall energy consumption characteristic of the vehicle queue can be improved, and the calculation complexity can be greatly reduced by only performing speed planning on the pilot vehicle.

    本发明涉及一种分层式车辆队列经济性驾驶协同控制方法,包括以下步骤:S1:构建纯电动车组成的车辆队列;S2:构建上层控制策略,对领航车辆规划经济性车速轨迹;S3:构建下层控制策略;S4:将步骤S2获得的领航车辆经济最优扭矩序列、当前的最经济车速和步骤3获取的领航车辆的当前状态信息通过车车通信V2V传达给各跟随车辆;S5:通过步骤S3中的下层跟车控制策略接收步骤S4传达的信息,并对队列跟随车辆进行优化控制,即完成对分层式车辆队列经济性驾驶的协同控制。本发明设计的分层优化控制策略,融合经济驾驶技术与队列协同控制技术,能提升车辆队列整体能耗特性,且只对领航车辆进行速度规划能大幅度降低计算复杂度。
