摘要

匹配多挡位变速器的纯电动客车可有效地提高加速能力和续驶里程，但换挡规律的设计面临着标定工作量大、成本高且过度依赖标定工程师经验等难题。为此，提出了一种基于模型的换挡规律设计方法，该方法可有效地缩短换挡规律开发周期。首先，采用动态规划优化标准循环工况下车辆的挡位切换序列；然后，以获得的换挡点为数据样本，采用聚类分析方法提取可直接用于实车控制器的换挡规律；最后，通过仿真验证了所提取换挡规律的有效性。结果表明，所设计的换挡规律能够兼顾动力性和经济性，与原换挡规律相比，循环工况耗电量可降低5.51%。

Abstract

The pure electric bus with multi gear transmission can effectively improve the acceleration ability and driving range. However， the design of shift schedule is faced with the problems of heavy workload， high cost and over dependence on the experience of calibration engineers. Therefore， a model-based shift schedule design method， which can effectively shorten the development cycle of shift schedule is proposed. Firstly， dynamic programming is used to optimize the shift sequence of vehicles under standard cycle conditions. Then， the shift points obtained are taken as data samples， and the shift schedule that can be directly used in vehicle controller is extracted by cluster analysis method. Finally， the effectiveness of the extracted shift schedule is verified by simulation. The simulation results show that the vehicle using the shift schedule designed in this paper can give consideration to both dynamic and economy. Compared with the original shift schedule， the cycle power consumption can be reduced by 5.51%.
