Abstract: In this paper, the design and implementation of electro-hydraulic control system for heavy mine dump truck are presented. According to the functional requirements of mine dump truck products, a distributed network structure based on CAN bus is designed, and the specific functions of vehicle control unit are designed, including the function design related to driving, such as transmitter start, throttle pedal, brake pedal and lighting, and the control method of hydraulic lifting valve block and the principle of electro-hydraulic combined braking, which are finally carried out. Selection of controller and development of application program to realize all control functions of electro-hydraulic control system of mine dump truck.
