Abstract
The automatic and intelligent degree of tractor hitch system determines the operations quality, efficiency, tractor power output and energy consumption, and automatic control of electro-hydraulic hitch is one of the key technical problems in the realization of automated tractor. In this study, the adjustment methods and characteristics of electro-hydraulic hitch system were summarized. The development of electro-hydraulic hitch control technologies was elaborated and analyzed from both the electro-hydraulic control strategy and slip control strategy perspectives. The implementation methods and control characteristics were discussed. A new idea for the development of automated tractor was put forward that integrating cutting-edge technologies such as big data, fusion control and artificial intelligence. In addition, based on the precise and efficient control of electro-hydraulic hitch system, a high reliability of the control system of the tractor with intelligent application of the control algorithm was obtained. The results can provide a reference for the precise operation of automated tractors under the big data in agriculture.
