The invention provides an energy management control method and system of a hybrid power vehicle and the vehicle, and relates to the technical field of hybrid power vehicles. According to the method, after the wheel end required torque of a driver is determined, the torque combinations of an engine and a motor under all available gears are traversed, the equivalent fuel consumption value under each torque combination is calculated, and the target torque combination corresponding to the minimum equivalent fuel consumption value under the current actual gear is found through comparison and optimization; the engine and the motor are controlled to output torque according to the engine torque and the motor torque under the target torque combination, the optimal target gear corresponding to the torque combination when the equivalent fuel consumption is minimum in the available gear range is found, and the gearbox is controlled to conduct gear shifting according to the optimal target gear. Not only are the dynamic requirement and the fuel economy requirement of the whole vehicle considered, but also the optimal system efficiency of the whole vehicle is realized.
本申请提供了一种混合动力车辆的能量管理控制方法、系统以及车辆,涉及混合动力汽车技术领域。本申请在确定驾驶员的的轮端需求扭矩之后,通过遍历所有可用挡位下发动机和电机的扭矩组合,并计算各个扭矩组合下的等效燃油消耗值,通过对比寻优,寻找到当前实际挡位下的最小等效燃油消耗值所对应的目标扭矩组合,并控制发动机和电机按照目标扭矩组合下的发动机扭矩和电机扭矩进行扭矩输出,以及寻找到可用挡位范围内等效燃油消耗最小时的扭矩组合所对应的最优目标挡位,并控制变速箱按照最优目标挡位进行换挡,不仅兼顾整车的动力性需求和燃油经济性需求,还实现了整车的系统效率最优。
