The invention discloses a hybrid-driven pedestrian overpass vertical ladder driving device and a control method, and belongs to the technical field of electro-hydraulic hybrid drive.The device comprises a high-voltage energy storage device, a low-voltage energy storage device, an elevator transmission device and a motor driving device; the elevator transmission device comprises a two-degree-of-freedom planetary gear train, the input end of the two-degree-of-freedom planetary gear train is connected with a motor driving device and an axial plunger pump and can be independently controlled, and the axial plunger pump is connected with a high-pressure energy storage device and a low-pressure energy storage device through control valves. The output end of the two-degree-of-freedom planetary gear train is connected with a transmission part of the elevator; the high-pressure energy storage device is connected with the photovoltaic power generation device through the metering pump and converts electric energy into hydraulic energy to be stored. The axial plunger pump is used for driving an elevator to work and storing hydraulic energy converted by the gravitational potential energy difference of two lift cars of the elevator into the low-pressure energy storage device. The device effectively improves direct dependence of a traditional elevator on a power grid, and energy consumption of the power grid is practically saved.
