摘要:

为了推动汽车节能国家标准的制定,研究了插电式和非插电式的混合动力汽车的道路预见性节能技术,并提出了一种测试评价方法。提出了用于道路预见性技术使用的地图数据信息及其标准化;采用全局动态规划算法,得到荷电状态(SOC)参考曲线;基于比例积分(PI)控制,实现参考SOC的跟踪控制;基于仿真结果分析初始SOC(20%~30%)、测试工况和测试里程等影响因素,提出转鼓实验法,实现标准化测试评价。对某车辆的转鼓测试的节能效果进行评价。结果表明:该车辆的转鼓测试,节能3.97%,SOC变化趋势符合预期。从而,证明了转鼓测试评价方法的可行性。

Abstract:

A standardized test-evaluation method was proposed for the hybrid electric vehicles with or without “plug-in” to investigate the predictive energy saving technologies for the national standards pre-research for automobile energy saving. By integrating map traffic information into road foresight technology, a set of critical data fields required for predictive energy saving was identified as well as the necessity of standardization was emphasized. The energy-saving mechanism was improved through dynamic optimization: the state of charge (SOC) reference trajectory was computed using global dynamic programming, and tracking control was achieved via PI control. Simulation analyzed influence of initial SOC (20%~30%) and test conditions on the energy-saving performance. Based on these findings, a dynamometer test method was developed to standardize evaluation processes. An evaluation was conducted on the energy-saving effects of dynamometer tests for a specific vehicle. The results indicate that the dynamometer test on the vehicle achieved a 3.97% energy saving, with the SOC variation trend aligning with theoretical expectations. This demonstrates the feasibility of evaluating energy-saving performance through dynamometer testing methods.
