Abstract: In a method for setting a command-response characteristic of an oil pressure control apparatus for each oil temperature, the command-response characteristic actually measured at a reference oil temperature is treated as a reference I-P characteristic. Then, a stroke-response characteristic is calculated based on the reference I-P characteristic, a thrust-force correlation and a restoring-force correlation. An overlapping length and a clearance width of overlapping areas between a sleeve and a spool of the oil pressure control apparatus are estimated based on the reference I-P characteristic and the stroke-response characteristic. Finally, the command-response characteristics for each oil temperature are decided and set based on the overlapping length and the clearance width.
