并联式混合动力汽车的基本控制策略和实时控制策略的比较分析

Comparison and Analysis of Baseline Control Strategy and Real-Time Control Strategy of HEV

基于上海市道路行驶工况,采用对混合动力汽车性能仿真的方法,对混合动力汽车的基本控制策略和实时控制策略进行了比较分析。结果表明基本控制策略主要针对混合动力系统的经济性能,是一种对发动机良好工作区域控制的方法,具有简单易行的特点;实时控制策略主要针对混合动力系统的经济性能和排放性能特别是NOx的排放性能,对发动机工作点进行了实时优化控制,更为全面和精确。

This paper compares and analyzes characteristics of baseline control strategy and real-time control strategy of HEV (hybrid electronic vehicle) on the basis of Shanghai road condition. The result shows that the baseline control strategy is designed for fuel economy but real-time control strategy for both fuel economy and emission performance, especially NOx. Also, the baseline control strategy is a control method of economic working region on the map and simple and easy in the engineering application; the real-time control strategy focuses on the real-time optimize of engine operating point on the map and has an accurate and multi-target characteristic.
