摘要
针对纯电动公交车性能水平良莠不齐,用户选车时缺乏指导的问题,力求建立运营性能评价指标体系,科学客观评价纯电动公交车在运营过程中的性能表现。在充分借鉴相关研究成果的基础上,针对用户对纯电动公交车性能的关注点,结合公交运营特性和纯电动汽车的技术特点,分析提出了初始指标体系,然后通过调查问卷收集了257位交通运输管理部门和公交企业专家的意见与建议,综合两轮调查意见优化指标内容,形成完整的指标体系。该指标体系分为动力性、经济性、安全性、舒适性、便捷性5个方面,包括加速时间、单位载质量能量消耗量、万公里当量故障率等14个指标。并利用实测数据、产品公告数据以及运行监测数据对部分指标进行试算。研究成果能够为公交运输企业、车辆生产厂家、车辆测评机构等开展纯电动公交车性能评价活动提供参考与借鉴,推动构建优胜劣汰的良好市场环境。
This paper aims to propose an indicator system to scientifically evaluate the performance of electric buses in the operation process,help bus companies to select and purchase high quality products.The initial evaluation indicator system of electric bus performance is built based on the analysis on the users’concerns,bus operation characteristics and the technical features of electric vehicles.Then the complete indicator system optimized and formed according to the opinions and suggestions by 257 experts from transportation management departments and bus companies through two rounds of questionnaire.The proposed indicator system is divided into five aspects:power,economy,safety,comfort,and convenience;and includes 14 indicators,such as acceleration time,unit load mass energy consumption,fault frequency per 104 kilometers and so on.Some indicators were calculated using the measured data,product announcement data and daily vehicle monitoring data.The research results can provide a reference for vehicle evaluation agencies,vehicle manufacturers,bus companies to carry out electric bus performance evaluation activities,and create favorable market environment of electric buses.
