Based on regional coordination,ecological coordinated development and status analysis,the development orientation of Xiaowang Town is studied and perfected deeply from space structure layout,road traffic planning,ecological landscape construction and residential space reconstruction. It is devoted to creating a suburban recreational resort and ecological livable new town with prominent industry function,distinctive style and feature,urban-rural integration,and hopes to provide certain reference for ecological construction of related towns at home and abroad.展开更多
文摘为降低重型商用车燃油消耗、减少运输成本,本文协调“人-车-路”交互体系,将车辆与智能网联环境下的多维度信息进行融合,提出了一种基于迭代动态规划(iterative dynamic programming,IDP)的自适应距离域预见性巡航控制策略(adaptive range predictive cruise control strategy,ARPCC)。首先结合车辆状态与前方环境多维度信息,基于车辆纵向动力学建立自适应距离域模型对路网重构,简化网格数量并利用IDP求取全局最优速度序列。其次,在全局最优速度序列的基础上,求取自适应距离域内的分段最优速度序列,实现车辆控制状态的快速求解。最后,利用Matlab/Simulink进行验证。结果表明,通过多次迭代缩小网格,该算法有效提高了计算效率和车辆燃油经济性。
