Control apparatus for controlling a shift operation in an automatic transmission |
摘要 |
A control apparatus for controlling a shift operation sets an output Mout from a reference model M(s), which is ideally changed, as a target slip amount of a feedback controller Cpi(s). The controller Cpi(s) controls torque transmitted to an off-going friction engagement element for matching a control slip amount sp with the target slip amount. The characteristics of the controller Cpi(s) is determined for optimally performing a clutch-to-clutch shift operation during a lock-up clutch being engaged. When the lock-up clutch has been disengaged, an input shaft rotation speed is filtered by a notch filter NF for removing a frequency component in a predetermined frequency domain, wherein the control slip amount sp is obtained based upon the filtered input shaft rotation speed. |
