Problems solved by technology

[0004] When the car is in the idling state, because the car needs to continue burning fuel to support the rotation of the engine, the energy generated by fuel combustion is wasted, so the fuel consumption of the car is relatively high in the idling state

Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0064] Such as figure 1 As shown, the embodiment of the present invention provides an engine shutdown system 00, the engine shutdown system 00 includes:

[0065] EMS (Engine Management System) 001 and engine 002.

[0066] EMS 001 is used to judge whether the engine 002 satisfies the shutdown enabling condition; when the engine 002 meets the shutdown enabling condition, judge whether the current state of the car is an idle state; when the current state of the car is an idle state, judge Whether the engine 002 meets the shutdown trigger condition; when the engine 002 meets the shutdown trigger condition, the engine 002 is controlled to stop.

[0067] To sum up, when the car enters the idling state, the EMS judges that the current state...

Abstract

The invention discloses an engine stop method and system, and belongs to the field of automobile starting and stop. The method comprises the steps that an engine management system (EMS) judges whether an automobile is in an idling state or not at present after the EMS determines that an engine meets stop enabling conditions, and if the automobile is in the idling state at present and the EMS determines that the engine meets stop triggering conditions, the EMS controls the engine to stop. The engine stop method and system solve the problem that oil consumption of an automobile is high when the automobile is in the idling state, achieve the effect that when the automobile is in the idling state, the engine is made to stop, and oil consumption of the automobile is reduced, and are used for stopping the engine.

Description

technical field [0001] The invention relates to the field of starting and stopping of automobiles, in particular to an engine stopping method and system. Background technique [0002] During the driving process of the car, traffic jams, red lights and other phenomena are often encountered. In this case, the car stops running and is in an idling state with the engine still running. [0003] In the prior art, an automobile includes an EMS (Engine Management System, engine management system), an engine, a gearbox, a clutch, a neutral switch, and the like. The transmission chain refers to the general term of the power transmission system of the car. The clutch or the gear position can control the disconnection and conduction of the transmission chain. When the clutch is pressed to the bottom or the gear position is in neutral, the transmission chain is disconnected. When the car is running, the transmission chain is in the conduction state, the power of the engine comes from th...
