The invention discloses a self-adaptive energy management system and method for a hybrid electric vehicle. The system comprises a mode discrimination module, a drive control module, a brake control module and a torque distribution module. The mode judgment module judges the working mode of the vehicle, and the drive control module and the brake control module adopt corresponding control strategiesto solve the ideal output torque of different power sources; the torque distribution module further distributes the output torque of the different power sources according to the output quantity of the drive control module or the brake control module; and the driving control module adopts an equivalent fuel consumption minimum control strategy. For the defect of poor working condition adaptabilityof a fixed equivalent factor in an equivalent fuel consumption minimum control strategy, an equivalent factor solving module is adopted to carry out fuzzy adaptive solution of the equivalent factor according to the road section average demand power predicted by an average power prediction module and the current state of charge of a battery; therefore, the fuel economy of the whole hybrid electricvehicle under the large-range road driving condition is remarkably improved.
本发明公开了一种混合动力汽车自适应能量管理系统及方法，该系统包括模式判别模块、驱动控制模块、制动控制模块、转矩分配模块。模式判别模块判断车辆工作模式，并由驱动控制模块和制动控制模块采用相应的控制策略求解不同动力源的理想输出转矩，转矩分配模块进一步根据驱动控制模块或制动控制模块的输出量进行不同动力源输出转矩的分配，驱动控制模块采用等效燃油消耗最小控制策略。针对等效燃油消耗最小控制策略中固定等效因子工况适应性差的缺点，采用等效因子求解模块根据平均功率预测模块预测的路段平均需求功率和电池当前荷电状态进行等效因子的模糊自适应求解，从而显著改善大范围道路行驶条件下混合动力汽车的整车燃油经济性。
