摘要： A method of calibrating an electrically controlled hydraulic valve (28, 32, 36, 40) having a known relationship between flow rate through the valve and displacement of a valve element (63, 73, 83, 93) is disclosed. The method includes ascertaining a first current level (IQ) for actuating the electrically controlled hydraulic valve to move the valve element to a position adjacent an inlet port, and a first displacement (Xo) of the valve element responsive to the first current level. The method also includes ascertaining a second current level (/2) for actuating the electrically controlled hydraulic valve to move the valve element from the position adjacent the inlet port to a position permitting flow through the inlet port, and ascertaining a second displacement (X2) of the valve element responsive to the second current level. The method further includes establishing a relationship between current and displacement associated with the electrically controlled hydraulic valve.
