In order to adapt the differential characteristics to the changing external conditions in the driving process, this paper mainly studies the key technology of the wheeled engineering machinery electronic anti-skid differential system. ATMEL89 C205 single-chip microcomputer is selected as the control core of the electronic anti-skid differential system. The system adopts fuzzy PID method to implement control. The working principle and hardware structure are explained. It introduces the software structure and the implementation methods of the main functional modules to achieve the optimal slip rate control target and improve the automatic control degree and the efficiency, so that the stability of the wheeled construction machinery operation is improved. The system better meets the automation and intelligent requirements of the control process, and provides reference for improving the function of the engineering machinery anti-skid differential system.
