The invention relates to a hybrid vehicle energy management method and system. The method comprises the steps of S1, randomly introducing a hybrid vehicle driving process, and collecting a state set,an action set, a return function and energy consumption in the driving process; S2, when a certain state xi appears in the state set, assigning the sum of the energy consumption corresponding to all the states after the state xi as a value of the return function, and recording all states with the energy consumption being the return function value; if the state xi does not appear, directly enteringthe step S3; S3, judging whether the cycle index reaches a preset cycle index or not, if not, returning to the step S1, continuing to execute the steps S1 and S2, and if so, entering the step S4; andS4, calculating an energy consumption average value corresponding to the recorded states, wherein the energy consumption average value is the optimal energy consumption of the hybrid power vehicle. According to the method, a Monte Carlo method is adopted to search for the optimal value and the optimal driving process of vehicle energy consumption, the calculation is accurate, and the efficiency is high.

    本发明涉及一种混合动力车辆能量管理方法和系统,包括以下步骤:S1.随机引入混合动力车行驶过程,采集行驶过程中状态集、行动集、回报函数和能耗;S2.当状态集中出现某一状态x时,将状态x后面的所有状态对应的能耗之和赋值为回报函数的值,并记录所有能耗为回报函数值的状态;如未出现状态x则直接进入S3;S3.判断循环次数是否达到预设循环次数,如未达到预设循环次数,返回S1,继续执行步骤S1和S2,如达到预设循环次数,则进入S4;S4.计算经过记录的状态对应的能耗平均值,能耗平均值即为混合动力车辆的最优能耗。该方法采用蒙特卡洛方法用来寻找车辆能耗的最优值和最优行驶过程,计算准确,效率高。
