The invention discloses a plug-in hybrid electric vehicle real-time energy management strategy based on model-free adaptive control. The energy management strategy is divided into an upper layer of the energy management strategy and a lower layer of the energy management strategy by adopting a hierarchical optimization control architecture; the strategy upper layer can output a control variable lambda in real time for control of the strategy lower layer through feedback of a vehicle target state and an actual state based on a feedback control principle; and the key control parameter of the strategy lower layer is a co-state variable lambda. On-line optimization of lambda under an unknown working condition can be realized through on-line control adjustment of the model-free adaptive controller, so that the adaptive capability of a lower-layer PMP strategy to the unknown working condition can be ensured, and the economical efficiency of a vehicle is ensured while the algorithm performance is improved. 本发明公开了一种基
