Abstract
A hydro-mechanical hybrid transmission device and a control method thereof are provided. The device includes an input shaft, a split mechanism, a mechanical transmission assembly, a hydraulic transmission assembly, and an output shaft, wherein the input shaft is connected, through the split mechanism, to the mechanical transmission assembly and the hydraulic transmission assembly that are connected in parallel, and the mechanical transmission assembly and the hydraulic transmission assembly are both connected to the output shaft. The mechanical transmission assembly includes a front planetary-gear-set assembly and a rear planetary-gear-set assembly. The front planetary-gear-set assembly and the rear planetary-gear-set assembly are connected in series. The control method includes three modes of transmission: pure hydraulic transmission, hydro-mechanical hybrid transmission, and pure mechanical transmission are implemented through combination and engagement/disengagement of gear-shift components.
