摘要： The disclosure provides an engine control method, system, and vehicle, and the vehicle comprises a battery and an engine, wherein the method includes: obtaining a current maximum discharge power value of the battery, and a current maximum external characteristic power value of the vehicle; obtaining a current opening value and a current opening change rate of an accelerator pedal of the vehicle; determining a driving intention based on the current opening value and the current opening change rate; and controlling start and stop of the engine according to the driving intention, the current maximum discharge power value, and the current maximum external characteristic power value of the vehicle. Since the driving intention is determined by the current opening value and the current opening change rate in advance, and based on the determined driving intention, in combination with the current maximum discharge power value of the battery and the current maximum external characteristic power value of the vehicle, the power response is carried out in advance so as to ensure that a larger power request can be satisfied at the next moment, thus avoiding the case where the engine is unnecessarily started or is not started in time.
