The invention discloses an automatic stalling method for an engine. The method comprises: a running state detection step of detecting the running state of a vehicle, wherein the running state comprises a stationary state and a motion state; a driving position detection step of judging whether a driver is at the driving position of the vehicle or not; an engine state detection step of detecting the movement state of the engine, wherein the movement state comprises a stopped state and a rotating state; an execution step of transmitting a stalling signal to an execution mechanism by using a controller in the stationary state and the rotating state under the condition of no driver, and stalling the engine by using the execution mechanism. Whether the vehicle is in the stationary state or not, whether the driver is at the driving position or not and whether the engine rotates or not are judged, and the engine is stalled under the conditions that the vehicle is in the stationary state, the engine is in the rotating state and the driver is not at the driving position, so that engine abrasion caused by the long-time operation of the engine is prevented, and meanwhile, energy sources are saved.
