Method and system for automatic engine flameout

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to an engine automatic flameout method and system. Background technique [0002] Most mid-to-high-end cars now use a one-button start device. The NVH performance of this car is absolutely beyond doubt. Under idling conditions, if you don’t listen carefully or feel it, it may be difficult for you to judge whether the engine of the vehicle is working. [0003] In this case, a small number of "Ma Daha" friends will make the mistake of Ma Daha --- when encountering an emergency, the driver forgets to turn off the engine after parking the car in the parking space, especially in the urban area or in the background In places where the noise is relatively loud, when the driver came back, he found that the engine of the car had been working, and even came back and found that there was no fuel in the fuel tank. [0004] Therefore there are following deficiencies: the driver forgets to...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a method and system for automatically turning off the engine, which solves the technical problem that the driver forgets to turn off the engine, and the engine continues to run after leaving, and cannot automatically turn off the engine, resulting in a waste of energy.
