摘要：: <p>PROBLEM TO BE SOLVED: To provide a control method and a control system of self calibrating a hydraulic operating device. SOLUTION: In a control method and a control system 10 self calibrating a hydraulic operating device of clutch actuator 24 or the like in an automatic transmission, a pressure switch 30 is provided in a hydraulic circuit, a feedback signal is supplied to a controller 32 in the case that a fluid pressure reaches a set point level. The pressure switch 30 supplies the signal to the controller 32, to compare a control signal of pressure in the set point level with a control signal of a calibration curve, and it is adjusted.</p>
