Abstract: In order to find the most economical curve of the diesel engine in the power match control of construction vehicle, the Matlab′s matrix operation,3D graphics drawing and equivalent method was investigated. After the analysis of the universal characteristic curve, the relationship of electriccontrol and engine was established. A method was presented to realize energy saving control based on the most economical curve for the real operation. The value of fuel consumption were evaluated on the vehicle, the effect of control were tested. The experimental results show that it is an effective way to improve the vehicle′s matching identity and ensure its working point in the economic region.
Key words: dieselengine; universal characteristic curves; most economical curve; Matlab; simulation; powersave
