Abstract (en)
The invention relates to a digital control method for a hydraulic ON/OFF valve, wherein the ON/OFF valve is controlled by a digital control signal (v), wherein the digital control signal has a number of successive cycles (T j , T j+1 ), wherein each cycle of the number of successive cycles has a pulse lasting a variable pulse period ( t i ) and a pause lasting a variable pause period ( t p ), wherein the pause period ( t p ) of each cycle is set taking into account the time when the ON/OFF valve reaches the OFF state after the pulse of the cycle.
