The method comprises the following steps: acquiring required running speed and load required power; and setting a revolving speed value of the engine to be minimum revolving speed on the premise of meeting the required running speed and the load required power. By the energy-saving control method and system for the revolving speed of the engine, the engine runs at economical revolving speed as much as possible on the promise of meeting a vehicle speed requirement and a power requirement, so that the purpose of saving fuel is achieved. Meanwhile, when the revolving speed set value of the engine is changed, a hydraulic system is adjusted in real time so as to guarantee stable running speed and link before and after change of the revolving speed, and stability and driving comfort are good. A power requirement serves as a first priority, and the revolving speed of the engine can be relatively high when high speed or large torque is required. Therefore, a vehicle can meet optional speed requirements. But the required speed of the vehicle is not maximum in most cases, and the advantage of fuel saving can also be played fully.
