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： There is provided a fail control apparatus for an automatic transmission, which, in the event of a friction element failure, is capable of coping with the failure by identifying a failed part without erroneous determination and within a short time. The set gear ratio of a designated gear position at the time of failure and the actual gear ratio are compared with each other to determine whether a friction element has failed, and an alternative gear position which enables a vehicle to start moving again is designated based on the determination result. In determining a failed friction element, one friction element disengaged or engaged due to failure is identified only when the designated gear position is the first speed gear position which is achieved by engaging one low clutch and a one-way clutch. It is therefore possible to determine the details of failure with accuracy and properly set an alternative gear position. On the other hand, when the designated gear position at the time of failure is other than the first speed gear position, in which a plurality of friction elements are engaged, one friction element which has failed is not identified, and it is therefore possible to quickly set an alternative gear position without the possibility of erroneous determination.

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 control system is provided with a disengagement malfunction determining section and a disengagement malfunction preventing section in an automatic transmission in which the frictional engaging elements are selectively engaged and disengaged to change a rotational speed of a main power source. The disengagement malfunction determining section determines a disengagement malfunction with a first frictional engaging element from among a plurality of frictional engaging elements of the automatic transmission. The disengagement malfunction preventing section prevents disengagement malfunction of a second frictional engaging element from among the frictional engaging elements of the automatic transmission by lowering the rotational speed of the main power source to a level which will prevent the disengagement malfunction in the second frictional engaging element, when the disengagement malfunction determining section determines that the disengagement malfunction of the first frictional engaging element exist while the automatic transmission is in non-running range.
