Abstract: 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.

Abstract: A hydraulic pressure control device for an automatic transmission is adapted to smoothly change the slip amount of the automatic transmission when a clutch to clutch shift control is performed. The hydraulic pressure control device uses a reference model showing a behavior with an output corresponding to a predetermined slip amount which smoothly varies over time with respect to a target slip amount which varies in a stepped manner. The hydraulic pressure is applied to a release side frictional engagement element using a controller CEMM (s) which shows a behavior such that the controller CEMM(s) and a controlled object P(s) are collaborated to correspond to the reference model. The controller CEMM(s) and the controlled object P(s) have the hydraulic pressure applied to the release side frictional engagement element of the automatic transmission as an input and the slip amount of the automatic transmission as an output.
