Control method for mixer truck, processor and mixer truck

The invention discloses a control method for a mixer truck, a processor and the mixer truck, and belongs to the technical field of mixer trucks. The control method comprises the steps that under the condition that an engine is started, the residual electric quantity of a high-voltage battery pack, the current rotating speed of the engine and the current working state of the mixer truck are obtained; determining an electric quantity interval where the remaining electric quantity is located; determining the output power of the generator according to the electric quantity interval, a preset fuel economic rotating speed interval, the current rotating speed and the current working state; and controlling the generator to work according to the output power so as to charge the high-voltage battery pack by the generator. The output power of the generator is determined in real time according to the electric quantity interval, the preset fuel economic rotating speed interval, the current rotating speed and the current w
