摘要： PROBLEM TO BE SOLVED: To provide a failure detecting device for an automatic transmission for a vehicle capable of correctly detecting abnormality in an engagement element by detecting rotation speed of one rotation element in addition to input rotation speed and output rotation speed in the automatic transmission for a vehicle.
SOLUTION: When rotation speed N
S2 of one intermediate rotation element (second sun gear S2) is detected among rotation elements that are not integrally rotated with an input shaft 18 or an output gear 20, among rotation elements in the automatic transmission 16, rotation speed of a prescribed rotation element that is different from above intermediate rotation element is determined based on rotation speed N
M of the intermediate rotation element with relation indicated by an expression in drawing 4. Differential rotation ΔN for an engagement element is determined to selectively connect the prescribed rotation element to another rotation element or a non-rotating member based on the rotation speed of the prescribed rotation element, and abnormality related to the engagement element is determined based on the differential rotation ΔN of the engagement element. Actuation defective of the engagement element in the automatic transmission 16 can thus be detected with favorable precision.

摘要： PROBLEM TO BE SOLVED: To prevent malfunction such as a racing anomaly during a power-on downshift of clutch-to-clutch shifting. SOLUTION: Since feedback control is carried out on a duty ratio DSL1 of a linear solenoid SL1 controlling a release side oil pressure PB1 of a brake B1 during the 4 to 3 power-on downshift and an ante-feedback correction value FB* at a start of the feedback control is changed when the racing anomaly or a tie-up anomaly occurs, the oil pressure PB1 is suitably controlled irrespective of a response delay of the feedback control and the downshift can be quickly carried out while preventing the racing anomaly and the tie-up anomaly. When a turbine rotating speed NT rises and it reaches a neighborhood of a synchronous rotating speed NTDWN after shifting, phase lag control is carried out (TRQ1), and when the racing anomaly occurs, the phase lag control is immediately carried out (TRQ2) to reduce an output of an engine.

摘要： PROBLEM TO BE SOLVED: To provide a down controller for a vehicular automatic transmission capable of suitably suppressing a shifting shock irrespective of dispersion in shifting time. SOLUTION: Since a back pressure of an accumulator AC3 is corrected by learning so that a slipping period TT from a shifting output for a power-on 5 to 4 downshift to a start of raising a counter rotational speed NC is brought closer to a target period TTM and a change rate R of the counter rotational speed NC is brought closer to a target change rate RM by an accumulator back pressure learning control means 122, the shifting shock is suitably suppressed irrespective of the dispersion in the shifting time in comparison with conventional learning and correction of the accumulator back pressure responding to a shifting period. Namely, even when the dispersion of shifting time increases, the shifting period does not exceed an operating range of the accumulator AC3, an original engagement pressure change alleviating function of the accumulator AC3 is provided and the shifting shock is suitably alleviated.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic stroke device capable of improving responsiveness by reducing sliding resistance regardless of reduction in the number of seal materials without the leak of an operating fluid, and a planetary gear automatic transmission and a clutch device using the hydraulic stroke device. SOLUTION: Since a rise of back pressure given from an oil passage 10i in a hydraulic piston 10 is not sufficient in the movement of the hydraulic for driving a brake of the planetary gear automatic transmission, responsiveness is improved with the low sliding resistance of O-rings 18 and 20 as shown in Fig. (A). Since the back pressure from the oil passage 10i is sufficiently increased while the hydraulic piston 10 is stopped in a pressurized state of a working fluid to enhance a sealing property by the O-rings 18 and 20 as shown by Fig.(B) the risk of the leak of the operating fluid is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a frictional engaging device of a vehicular automatic transmission superior in responsiveness of hydraulic pressure by bleeding air in a piston hydraulic chamber without causing leakage of a hydraulic fluid when supplying the hydraulic pressure.
SOLUTION: A piston 72 is positioned on the support wall 36a side at the beginning of supplying the hydraulic fluid in the hydraulic chamber 76, and at this time, since a ventilation passage 90 is positioned over a rubber member 88, air in the hydraulic chamber 76 is exhausted via a ventilation passage 90. Afterwards, when the piston 72 advances to the frictional engaging element 66 side, since the ventilation passage 90 is positioned in the hydraulic chamber 76 on the support wall 36a side more than the rubber member 88, the hydraulic pressure in the hydraulic chamber 76 can be held without leaking the hydraulic fluid. As a result, hydraulic pressure reduction in the hydraulic chamber 76 is prevented, and the deterioration in controllability caused by the hydraulic pressure reduction in the hydraulic chamber 76 can be prevented.
