摘要： An automatic transmission has a transmission control section performing a control so that a transmission ratio defined as input rpm/output rpm of the automatic transmission becomes a target transmission ratio, a slip control section slip-controlling a frictional engagement element in the automatic transmission so that the input rpm becomes a value obtained by multiplying the output rpm by the target transmission ratio also adding a predetermined slip revolution speed; and an abnormality judgment section judging abnormality in the automatic transmission. When the slip-control is not in progress, if an actual transmission ratio is out of a predetermined range of the target transmission ratio, the abnormality judgment section judges that abnormality occurs. When the slip-control is in progress, if a value obtained by correcting the actual transmission ratio on the basis of the slip revolution speed is out of the predetermined range, the abnormality judgment section judges that abnormality occurs.

摘要： An automatic transmission control unit determines whether or not a constantly open failure, in which a switch valve cannot switch a pressure regulating valve and a second hydraulic chamber to a non-communicative state, has occurred on the basis of a parameter (an inertia phase time, for example) representing a dynamic characteristic during a shift from a first gear position to a second gear position. The determination of the constantly open failure is begun after initial variation in the parameter representing the dynamic characteristic during the shift has been eliminated through learning control in which the dynamic characteristic during the shift is caused to approach a target dynamic characteristic.

摘要： An automatic transmission system includes a transmission having transmission elements with lubrication-requiring portions and hydraulic actuators therefor, a switching valve that supplies hydraulic fluid to the hydraulic actuators, a valve actuator that actuates the switching valve, a shift range detection unit that detects a selected shift range of the transmission, and a control unit that controls the valve actuator to actuate the switching valve in accordance with the selected transmission shift range. The switching valve has a bypass position to provide a supply of the hydraulic fluid to the lubrication-requiring portions by bypassing a transmission oil cooler. The control unit judges whether the transmission is in a low lubrication state based on a given operating parameter of the transmission and controls the valve actuator to switch the switching valve to the bypass position at the time the transmission is judged as being in the low lubrication state.
