Latest Patents

Among Lorenzo's latest inventions is a patent for a hydromechanical transmission and control method. This innovation proposes methods and systems for controlling a hydromechanical transmission, featuring a hydrostatic unit that includes both a hydrostatic pump and a hydrostatic motor. The control method utilizes a feedforward control architecture, employing a non-linear, multi-coefficient model to regulate the hydrostatic unit. Inputs such as the desired differential pressure or the desired hydraulic pump displacement are used to produce a model output, which dictates the pressure difference for a pump control piston connected to the unit's swash plate. This non-linear model allows control based on load, speed, and torque, significantly increasing the adaptability of the control system.

Another significant patent is the hydraulic system featuring a smart relief valve and valve control method. This system includes a boost pump and a relief valve connected to a reservoir, along with multiple control valves that interface with various hydraulic devices. The innovative controller adjusts the relief valve's position based on the aggregate hydraulic pressure demands of these devices, enabling precise boosts in hydraulic fluid pressure supplied to the control valves.
