VERFAHREN ZUR STEUERUNG EINES MIT EINEM FAHRZEUGMOTOR VERBUNDENEN MAGNETORHEOLOGISCHEN FLUIDLAGERS

A method of the invention is for controlling an MR-fluid hydraulic mount (12) connected to a vehicle engine. The mount includes an internal MR-fluid cavity (14). The mount includes a partition plate assembly (16) partitioning the cavity into first and second MR-fluid chambers (18,20). The partition plate assembly has an orifice (40) extending from the first MR-fluid chamber to the second MR-fluid chamber. The mount includes an electric coil (42) positioned to magnetically influence the orifice. The method includes, when the vehicle engine is at idle, determining a reference pressure as a fluid pressure within the second MR-fluid chamber. The method includes, when the vehicle engine is above idle, determining a command electric current to be applied to the electric coil using at least a difference between the reference pressure and a current fluid pressure within the second MR-fluid chamber. The method includes applying the command electric output current to the electric coil.
