Abstract

The present invention relates to the field of new energy construction machinery, in particular to a serial heavy hybrid construction machinery transmission system and a control method thereof, the system includes a mechanical transmission system, an electrical connection system and a control system, the engine output shaft is connected to a clutch, and an ECU system They are respectively connected with the engine, clutch, hydraulic system, motor generator, motor controller, power battery, electric motor, gearbox and other systems. The ECU system collects signals in real time for data analysis and processing. Combined with the characteristics of construction machinery's own working conditions, it formulates fuzzy logic control strategies, plans the working modes of engines, motor generators and motors, and solves online real-time adaptive and robust control problems.

Description

technical field [0001] The invention relates to the field of new energy construction machinery, in particular to a series-type heavy hybrid construction machinery transmission system and a control method thereof, which are suitable for scraping construction machinery with multiple power outputs. Background technique [0002] Construction machinery has the disadvantages of high energy consumption, poor emissions, low engine efficiency, and high noise. More and more attention has been paid to energy saving issues. Therefore, hybrid technology, new transmission technology, intelligent control technology and other related new technologies need to be widely promoted and applied. . [0003] The working environment of construction machinery is complex and changeable, and it is often necessary to work in special working conditions such as underground mines, flammable and explosive areas, low-noise areas, thin air areas, and indoor operations. [0004] Hybrid systems can achieve ene...
