The present invention discloses an engine control method, device, system, and a vehicle. The method includes: detecting execution information for controlling start-stop of an engine, wherein the execution information for controlling the start-stop of the engine at least includes a collected value of an acceleration sensor, a real-time vector velocity, and a value of torque requested by a driver; obtaining an instantaneous acceleration according to a ratio of the real-time vector velocity to time; calculating an acceleration of the vehicle according to the collected value of the acceleration sensor and the instantaneous acceleration; filtering the acceleration to obtain a filtered value of the acceleration and obtaining a value of slope by converting with a conversion relationship between the filtered value of the acceleration and the slope; and controlling the start-stop of the engine according to the value of the slope and the value of the torque requested by the driver. According to the technical solutions of the present invention, not only the value of the slope but also the value of the torque requested by the driver are considered in the conditions of the start-stop of the engine on a ramp, therefore the fuel consumption of the vehicle is effectively reduced.
