Optimization of Control Parameters of Atkinson Engine for Incremental Electric Vehicle

本文利用ADVISOR软件对某款汽车的性能参数进行研究,为研究整车发动机的使用性能,对功率跟随控制策略的主要参数变化进行分析,对SOC的上下限值、发动机的输出功率和发动机瞬时功率变化速度参数优化,得到一组控制参数使整车100km油耗与排放性能达到较为理想的状态,为后续研究增程式电动汽车动力性能及经济性能提供参考。

In this paper, ADVISOR software was used to study the performance parameters of a car. In order to study the performance of the vehicle engine, the main parameters of the power following control strategy were analyzed. The upper and lower limits of the SOC, the output power of the engine and the speed parameters of the instantaneous power of the engine were optimized, and a set of control parameters were obtained. The fuel consumption and emission performance of the 100km could reach an ideal state, so as to provide reference for subsequent research on the dynamic performance and economic performance of the extended electric vehicle.
