Due to the multiple types of support tasks and high energy efficiency equipment, energy saving research in a Bergepanzer has attracted much attention in recent years. In this paper, the energy consumption of the valve-controlled hydraulic luffing system (VHLS) of a Bergepanzer has been analyzed with the help of simulation and experiment, including the main reasons for low efficiency. In addition, a new hydraulic hybrid luffing system (NHLS) based on CPR, was designed. The structure and the working principle of the NHLS were analyzed. Furthermore, a hybrid control method, which combined the switching preset control angle based upon the input signal and pressure feedback and Fuzzy PID control was put forward for the NHLS. The commercially available software, Simulink, was used to carry out the simulation of the energy consumption of NHLS. Finally, the energy transfer efficiency of the system, and the energy transfer efficiency of the VHLS and NHLS systems were compared. The results showed that the NHLS exhibited good control, while the NHLS could significantly reduce the system's energy consumption and increase its energy utilization rate.
