摘　　要：针对特种车辆功率浪费严重的现状,提出将负载敏感技术应用到特种车辆的液压系统以减少节流、溢流损失,并详细分析了负载敏感系统的工作原理。同时,为降低特种车辆发动机的燃油消耗率,提出了基于转速、油门双闭环的PID控制系统方案,以保证发动机的工况点始终落在万有特性曲线的经济区内,从而达到节约燃油的目的。After technology was the detailed analysis of the principle of load sensing system, the load sensing suggested to be used in especial vehicles to reduce the losses of throttle and overflow in the hydraulic systems, which was based on the serious situation in power losses in the especial vehicles. Besides, to reduce the fuel consumption rate of the engine, the PID control system including a speed loop and an accelerograph loop was put forward to ensure the engine condition he in the saving area in the curve of engine mapping characteristics.
