基于FDP的模块化电动重载车辆的能量分配与换挡策略
Energy distribution and shift strategy of modular electric heavy-duty vehicles based on FDP
摘要
Abstract
For the dual powertrain configuration proposed in this paper,there is currently no energy management strategy that effectively balances vehicle economy and comfort.When using dynamic programming algorithms,there are problems such as slow computational efficiency,difficulty in online application,and interpolation leakage.This paper describes a method to optimize dynamic programming algorithms using reduced state-space feasible domains and gear-holding func-tions.Firstly,an economy-oriented strategy is proposed,and then the state space feasible domain of dynamic planning is reduced using the extracted rules,the method of selecting state of charge(SOC)as the state variable is discarded,and a perfect energy management strategy is obtained by adding a block holding function to the cost function.The results show that this strategy reduces the transmission gear switching and the number of motor start-stops dramatically at the cost of consuming very little more energy,effectively balancing the economy and comfort of the vehicle.关键词
