摘　　要：为解决智能网联环境下混合动力汽车(HEV)队列通过连续交通信号灯路口时的舒适和经济性问题,提出一种基于网联HEV队列的生态驾驶与能量管理分层控制方法。上层控制器针对连续交通信号灯路口建立目标车速规划模型;根据目标车速范围建立纵向约束限制,建立以安全、舒适、跟随、经济和通过性为指标的目标函数;并采用模型预测控制(MPC)算法求解多目标函数获得最优车速。下层控制器采用深度强化学习(DQN)算法优化混合动力汽车能量管理,将上层求解的最优车速作为下层输入获取发动机电机的最优输出。结果表明:该文所提控制策略可以保证汽车队列的行驶安全,生态驾驶汽车队列平均油耗比普通队列降低了8.51%,在避免停车等待的同时改善了乘坐舒适性和燃油经济性。In order to solve the problem of comfort and economy of hybrid electric vehicle(HEV)queues passing through continuous traffic signal intersections in a smart grid environment,a hierarchical control method of ecological driving and energy management based on networked HEV queue was proposed.The upper-level controller developed a target speed planning model for intersections with continuous traffic lights.Based on the defined target speed range,longitudinal constraint limits were established,and an objective function encompassing safety,comfort,following behavior,economy,and passability was formulated.The multi-objective function was solved using a model predictive control(MPC)algorithm to determine the optimal vehicle speed.Meanwhile,the lower controller adopted deep reinforcement learning(DQN)algorithm to optimize the energy management of the HEV,and took the optimal speed solved by the upper layer as the input of the lower layer to obtain the optimal output of the engine motor.The results show that the proposed control strategy can ensure the driving safety of the car queue,and the average fuel consumption of the eco-driving car queue is reduced by 8.51%compared with that of the ordinary queue,improving the ride comfort and fuel economy while avoiding the parking wait.
