The invention belongs to the technical field of hybrid power vehicles, and particularly relates to a hybrid power vehicle energy management control method and device. The method comprises the steps that future working conditions are predicted firstly, then an energy consumption model of a vehicle is established and used for representing the relation between engine control power, motor control power and total oil consumption, and the total oil consumption is equal to the sum of real oil consumption of an engine and equivalent oil consumption of a battery; then, according to the speed in the prediction time period, the change condition of the vehicle speed is determined, the equivalent factors are adjusted in real time, the energy consumption model is solved with the minimum total oil consumption value as the target, and the optimal engine control power and the optimal motor control power are obtained; and performing vehicle control with reference to the optimal engine control power and the optimal motor control power. According to the method, the energy consumption model is changed and adjusted in real time according to the change condition of the vehicle speed, so that the vehicle obtains good fuel economy in real time during driving in the prediction time period, the complex and changeable future working conditions are coped, and it is guaranteed that energy consumption is low in real time.

    本发明属于混合动力车辆技术领域,具体涉及一种混合动力车辆能量管理控制方法及装置。该方法首先预测未来工况,然后建立车辆的能耗模型,用于表示发动机控制功率、电机控制功率与总油耗关系,且总油耗等于发动机真实油耗与电池等效油耗之和;接着根据预测时间段内的速度,确定车辆速度的变化情况,时时调整所述等效因子,并以总油耗值最小为目标求解所述能耗模型,得到最优的发动机控制功率和最优的电机控制功率;参照该最优的发动机控制功率和最优的电机控制功率执行车辆控制。本发明实现能耗模型依据车辆速度的变化情况而时时变化与调整,以使车辆在预测时间段内行驶时时获得良好的燃油经济性,应对复杂多变的未来工况,时时保证能耗较低。
