To Improve the comprehensive economy of Hybrid Electric Velicle (HEV) in driring, aiming at the problem of insufficient adaptability of existing HEV energy management strategies to drivers with different driving styles an adaptive equivalent consumption minimization energy management strategy based on real-time recognition of driving styles is proposed. Firstly, the changes in driving demand caused by the real-time pedal signal variation are analyzed, and the real-time driving styles in the rolling time window by data characteristic extraction is identified. Then, in the equivalent consumption minimization strategy considering the cost of battery degradation, and an adaptive function of equivalent factor is constructed by quantifying the driving style coefficient, and the optimal equivalent factor and battery degradation cost weighting coefficient corresponding to different driving styles are solved. Based on this, an adaptive law for equivalent factor based on artificial potential field method is designed. The simulation results showed that, compared with the equivalent energy consumption minimization without consideration of driving style, the proposed method improves fuel economy by 2.82% while reducing the battery loss by 25% under the same driving condition.
