Problems solved by technology

[0005] However, in conventional construction machines, there was a problem that the engine control unit caused inconvenience and accidents
Specifically, when the engine control unit is operated, it always takes a predetermined time to stop the engine 10, and the engine 10 cannot be stopped in between.
That is, when the engine 10 needs to be stopped immediately although the engine control unit is in operation (for example, when the driver needs to get off the construction machine in an emergency, when a fire occurs, when the start of the construction machine is abnormal, etc.), the engine 10 continues is activated, and there is a problem of causing inconvenience to the driver or causing an accident

Abstract

The present invention relates to a construction machine comprising: an engine for generating power; an ignition switch for turning on and off a power supply of an electric component; an engine control unit that, when the ignition switch is switched from an on (ON) state in which the power supply of the electric component is turned on to an off (OFF) state in which the power supply of the electric component is turned off, stops the driving of the engine after maintaining for a predetermined time; and a vehicle control unit that transmits a signal to forcibly stop the engine when in a predetermined condition, whereby inconvenience and accidents caused by the engine control unit can be prevented.

Description

technical field [0001] The present invention relates to a construction machine, and more specifically, to a construction machine capable of performing civil engineering or construction work. Background technique [0002] Generally, a construction machine is, for example, a machine used for civil engineering or construction work like an excavator, a loader, and includes: an engine that generates power; a drive section that is activated by receiving power generated by the engine; and an engine control A unit for an engine control unit for preventing damage to an aftertreatment device by delaying engine stop in a state in which the aftertreatment device aftertreatment of gas exhausted from the engine is at a high temperature. [0003] figure 1 is a system diagram showing a conventional construction machine, and is a system diagram showing a case where the ignition switch is turned on, figure 2 is showing figure 1 A system diagram of the construction machine in which the ign...
