针对再生制动时能量回收效果的评价缺少有针对性的标准循环工况,构建了一种基于多元统计学概率分布理论的标准循环工况。提出了城市再生制动标准循环工况的构建方法,对采集的北京和天津道路工况数据进行了统计分析与处理。结合马尔可夫分析,构建了大型城市再生制动标准循环工况。对比试验结果表明,大型城市再生制动标准循环工况是有效的,对于其他城市再生制动标准循环工况的制订具有实用价值。
For the evaluation of energy recovery effect when regenerative braking is lack of targeted standard cycle conditions, a standard cyclic operating condition based on multivariate statistical probability distribution theory is constructed. The construction method of urban regenerative braking standard cycle condition was put forward, and the collected data of road conditions in Beijing and Tianjin were statistically analyzed and dealt with. Combined with Markov analysis, a large-scale urban regenerative braking standard cycle condition is constructed. The results of comparative tests show that the recirculation conditions of regenerative braking standards in large cities are effective and have practical value for the development of recirculation conditions of regenerative braking standards in other cities.
