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.

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 is provided with at least one friction element and a piston. The engagement of the friction element is proceeded in a manner that operating pressure is applied to an apply chamber to stroke the piston. The disengagement of the friction element is proceeded in a manner that operating pressure is applied to a cancel chamber to stroke the piston. The cancel chamber is disposed opposite to the apply chamber with respect to the piston and formed such that an outer diameter of a pressure receiving surface of said cancel chamber is generally the same as that of said apply chamber. Therefore, piston pushing force due to centrifugal force in the apply chamber is balanced with a piston reversely pushing force due to the centrifugal force in the cancel chamber. This prevents the friction element from being dragged during friction element disengaged condition.

摘要： An automatic transmission includes first and second planetary gear sets, and a third planetary gear set which is closer to an output end of the transmission, and which is smaller in diameter than the first and second gear sets. One brake is disposed around the first and second planetary gear sets, and another brake has a pack of brake plates surrounding the smaller third planetary gear set. A transmission case is therefore made gradually smaller toward the output end. This planetary gear system makes it possible to arrange the brakes very compactly, and the tapered transmission case improves the rigidity of the automatic transmission.
