摘要:

研究了车辆编队的生态驾驶问题。为了降低车队避开红灯的概率,提高燃油效率,提出了一种双层控制结构。第一层负责利用交通灯和道路坡度信息优化领导者的长期运动轮廓。在分析车队对绿灯窗口可达性的基础上,建立了车队的长期规划模型。提出了一种事件触发机制来运行长期规划模型。第二层是短期适应,其中领导者尝试实时跟随规划运动轮廓,而跟随者跟踪最近的前车和领导者,以保持期望的车间距。一个牛顿的方法为基础的算法,有效地解决长期规划和短期适应问题。仿真结果表明了所提出的公式和算法的有效性。

英文摘要:

This paper investigates the problem of ecological driving (eco-driving) of vehicle platoons. To reduce the probability of the platoon avoiding red lights and increase fuel efficiency, a two-layer control architecture is proposed. The first layer is in charge of optimizing the leader's long-term motion profile using the traffic light and road slope information. The long-term planning model is defined based on the reachability analysis of the platoon to the green light windows. An event-triggered mechanism is proposed to operate the long-term planning model. The second layer is the short-term adaptation, in which the leader attempts to follow the planning motion profile in real time, while the follower keeps track of the nearest preceding vehicle and the leader, to preserve the desired inter-vehicular distances. A Newton's method-based algorithm is implemented to effectively solve both the long-term planning and short-term adaptation problems. The effectiveness of the proposed formulation and algorithm is illustrated by the simulations.
