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 re
