Problems solved by technology

However, these and other approaches to enhancing the performance of internal combustion engines often conflict with increasingly stringent emissions regulations, particularly those related to exhaust and visible smoke emitted from the engine in response to sudden and rapid increases in load on the working hydraulic system

Embodiment Construction

[0018] According to a preferred embodiment, the method comprises detecting at least one operating parameter indicative of a current operating condition of at least one of the power source and / or the power consumer. Sensing the operating parameters for these subsystems (i.e., power source, drive train, and working hydraulics) forms a useful tool for balancing or oncoming power at the summing point, compared to sensing the operating parameters for the summing point. Balance provides the conditions indicated earlier, especially if that summing point is the flywheel.

[0019] According to yet another preferred embodiment, the method comprises detecting at least one operating parameter by detecting at least one input command from an operator of the working machine. Detecting the commands given to the subsystems provides an earlier indication of the power balance at the summing point or the imminent power balance. In addition, by detecting operator commands, accurate predictions of...

Abstract

The invention discloses an operation method of construction machinery, the construction machinery is provided with: a power source providing power and a plurality of power consumption systems connected to the power source, the method is characterized in that The steps of: providing a prediction model for predicting the required power of at least one of the power consumption systems; balancing the provided power to the required power according to the prediction model, and connecting the power consumption system connected to said power source, and said predictive model includes a power summing point representing said branch portion, and when said predictive model indicates at said summing point, between said power source and said power consuming system When the power exchanged between is less than or will be less than zero, the provided power is balanced to the required power. Sudden rapid increases in load on various power demand and / or torque demand subsystems within the work machine may be balanced.

Description

technical field [0001] The invention relates to an operation method of construction machinery. Background technique [0002] A wheel loader typically has an internal combustion engine, drive train, gearbox, drive wheels and working hydraulics. [0003] The internal combustion engine powers the different functions of the wheel loader. Specifically, the internal combustion engine powers the drive train and working hydraulics of the wheel loader. [0004] The driveline transfers torque from the internal combustion engine to the transmission, which in turn provides torque to the drive wheels of the loader. In particular, the gearbox provides different gear ratios for changing the speed of the drive wheel and for changing between the forward and reverse drive directions of that wheel. [0005] The working hydraulic system is used for lifting operations and / or for steering the wheel loader. For this purpose, at least one hydraulic cylinder is arranged in the wheel loader for r...
