能量最优速度轨迹:电力传动系统效率特性的影响

On Energy Optimal Speed Trajectories: The Impact of Electric Powertrain Efficiency Characteristics

Arian Ahmadi, Peter H. Bauer

摘要:

本文研究了动力系统效率图对能量最优速度轨迹,特别是停车轨迹的影响。探索了各种不同的效率图,并进行了能量优化过程。结果表明,虽然效率图可以有一个显着的整体运输能量的影响,他们的最佳速度曲线的形状影响不大。许多非常不同的效率图和它们对速度轨迹的影响进行了说明。此外,车辆和段参数以及平均速度对节省的影响进行了研究。本文还介绍了瞬态惩罚的能量最优轨迹的形状和相关的节省的影响。据观察,通过添加额外的瞬态惩罚的能量平衡,轨迹的形状的变化和能量节省减少。

英文摘要:

This paper investigates the effect of the powertrain efficiency map on energy optimal speed trajectories, especially stop-to-stop trajectories. A variety of different efficiency maps are explored and the energy optimization process is carried out. It is shown that while the efficiency maps can have a significant impact on the overall transportation energy, they have little impact on the shape of the optimal speed profiles. A number of very different efficiency maps and their effects on speed trajectories are illustrated. Also, the impact that vehicle and segment parameters as well as average speeds have on the savings are investigated. This paper also presents the impact of transient penalty on the shape of the energy optimal trajectories and associated savings. It is observed that, by adding an additional transient penalty to the energy balance, the shape of trajectories changes and energy savings decrease.
