The embodiment of the invention discloses an energy-saving control method and device for an electric truck and a medium. Comprising the following steps: determining a preset reference motor efficiency high-efficiency area based on vehicle information of the electric truck; obtaining current road condition information and accelerator pedal opening information, and adjusting a preset reference motor efficiency high-efficiency area based on the current road condition information and the accelerator pedal opening information to obtain an actual motor efficiency high-efficiency area; under the condition that the electric truck is in the non-full-load state, a vehicle preset economic mode is started; when the vehicle is in the running process of the vehicle preset economic mode, the current rotating speed and the current torque of the electric truck are obtained; and based on the actual motor efficiency high-efficiency area, the current rotating speed, the current torque and a preset double-speed-ratio drive axle, the driving state of the electric truck is adjusted, so that energy-saving control over the electric truck is achieved. By means of the method, the power performance of the vehicle can be kept while the vehicle saves energy.
