Title: METHOD FOR RECOGNIZING DIFFICULTY LEVEL OF WORKING CONDITION OF LOADING MACHINE
Abstract:
A method for recognizing the difficulty level of a working condition of a loading machine, comprising: taking an excavation operation section obtained through extraction of an operation section as a main research object and recognizing a working condition so as to finally obtain a value of the difficulty level of the working condition. Recognition of the difficulty level of the working condition facilitates control of a power output mode of a diesel engine, thereby achieving on-demand distribution. The recognition is also taken as a judgement basis of an intelligent shifting control strategy, and has significance for intelligent shifting of an engineering vehicle, power mode control, improvement of an operation performance, etc., thereby facilitating the improvement of the operation performance, energy conservation and emission reduction. By means of the difficulty level of a working condition, variable power adjustment is achieved, and the application range of engineering machinery is extended. One machine can be used for multiple work media, so one machine having multiple functions is actually achieved. One machine can be used in working scenarios with multiple media, so the operation performance and the intelligent level of the machine are improved.
