摘要：AbstractEquivalence factor plays a key role in equivalent consumption minimization strategy and due to its strong relevance with driving cycle, the change of driving cycle can be reflected by the equivalence factor and at the same time different driving cycle has different equivalence factor. In this paper, the optimal equivalence factor as one of the control variables is calculated by dynamic programming. The three initial maps of the optimal equivalence factor concerning state of charge and power demand are formulated over NEDC, UDDS, 10-15 mode cycle respectively. These maps are fused together to obtain the final one for simulation analysis. Compared with the rule-based control strategy, the proposed method has a better fuel economy over NEDC, UDDS, 10-15 mode cycle.
