A SELF-CALIBRATING SYSTEM AND METHOD FOR CONTROLLING A HYDRAULICALLY OPERATED DEVICE |
摘要 |
<p>A self-calibrating method and system 10 for controlling a hydraulically operated device, such as a clutch actuator 24 in an automatic power transmission, provides a pressure switch 30 in the hydraulic circuit that provides feed-back to the controller 32 when the hydraulic fluid pressure has reached a set point level. Pressure switch 30 provides a signal to controller 32 that allows the controller to compare the control signal at the pressure set point level with that of the calibrated curve for adjusting the calibration curve.</p> |
