First of all, the energy saving control of hydraulic excavator in China and aboard are related, and the control methods are summarized in this paper. For the sake of energy saving control research, a hydraulic excavator electronic energy-saving control model is established based on CAN-bus technique. And then the aspect of the speed control of the engine is focused on, a cascade control is used, an inner feedback loop gives control over the governing throttle and an outer feedback loop does the speed regulation. The use of feed forward of the load demand, when a signal is available which is proportional to the load, then the signal can be fed forward to the input of the control system to anticipate changes in load. The power limiting control ensures optimum use of the power required for the excavator under varying operating conditions and avoids overload of the diesel engine, with the diesel engine, variable pump, and the loads as the whole dynamic system, the overall power match technique is proposed, and transfered the point match to area match by the method of area power match, so the energy efficiency is improved.
