Problems solved by technology

When the system controlling this power mode recommendation method only recommends the power mode that consumes the lowest amount of fuel, the engine angular velocity may decrease
Therefore, the operator may not be satisfied with the operating speed at light load conditions, because the maximum operating speed is determined by the engine angular velocity at light load conditions

Abstract

A power mode recommendation system for a construction machine including a hydraulic system driven by working fluid supplied by a hydraulic pump. A controller configured to analyze engine torque, flowrates of working fluid in use, amounts of fuel consumption of the plurality of power modes and to recommend a power mode indicating lowest fuel consumption, from among the plurality of power modes, using the analysis. A human-machine interface (HMI) device displays the power mode recommended by the controller to an operator. The system recommends an efficiency power mode to an operator by analyzing not only the amount of fuel consumed by the construction machine, but also flow rates of working fluid in use and operating speeds.

Description

technical field [0001] The present disclosure relates to a power mode recommendation system for construction machinery. More specifically, the present disclosure relates to a power mode recommendation system for a construction machine that analyzes not only the amount of fuel consumed by the construction machine but also the flow rate and operating speed of a working fluid in use, the power mode recommendation system An efficient power mode can be recommended to the operator. Background technique [0002] When working with construction machines such as excavators, some operators may set the high power mode even when performing light load operations. However, this habit can lead to wasted fuel. [0003] In the prior art, a method of recommending an appropriate power mode to an operator has been proposed in order to overcome the problem of wasting fuel. This power mode recommendation method is designed to recommend the power mode that indicates the lowest fuel consumption o...
