摘要： PROBLEM TO BE SOLVED: To provide a shift controller for a vehicular automatic transmission sufficiently suppressing a shifting shock or the like even against disturbance such as vehicular braking even without providing a highly accurate control apparatus in clutch-to-clutch downshift control during coasting. SOLUTION: Since an oil pressure within a shifting period of a hydraulic frictional engagement device regarding a coast downshift is set in response to a minute vehicular driving state by an oil pressure setting means 120, an engagement pressure of the hydraulic frictional engagement device within the shifting period is suitably controlled. For example, an initial oil pressure PB11 of an engagement pressure PB1 of a brake B1 and an initial oil pressure PC11 of an engagement pressure PC1 of a clutch C1 regarding a clutch-to-clutch 4 to 3 downshift are suitably set within a 4 to 3 downshift period. By this, accuracy of engagement operation is secured irrespective of the disturbance such as the vehicular braking, and the shifting shock or the like is sufficiently suppressed.

摘要： PROBLEM TO BE SOLVED: To resolve problems in a power-on state during a coast down where a throttle opening is opened when both a high speed stage side engaging means and a low speed stage side engaging means are in disengaged states, and engine racing and an engagement shock following this occur. SOLUTION: During the coast down, a difference NE-NT between an engine speed and a turbine rotating speed is detected and recorded. The difference represents an absolute engine output based upon a vehicular load, and in the power-on state, the throttle opening θT1 is determined by adding a regulating amount θD determined on the basis of the difference to a basic throttle demanded opening θI and the engine speed NE and the turbine rotating speed NT are raised while maintaining the difference.

摘要： PROBLEM TO BE SOLVED: To reduce shocks and abnormal sounds caused by a change in a torque transmitting direction of a torque converter during a reverse input state when increasing engine output and spontaneously raising engine speed in a coast downshift. SOLUTION: In the coast downshift, whether or not it is in the reverse input state of the engine speed NE lower than a turbine rotating speed NT is determined (S2) and if it is in the reverse input state, the engine speed NE is gradually raised by controlling an opening of an ISC valve at a predetermined rate αof change at steps S3 and S4. By this, the torque transmitting direction of the torque converter is gradually changed, and shocks and abnormal sounds such as rattling noise following the change of the torque transmitting direction is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a down-shift controlling device for automatic transmission for vehicle with which the generation of a shock caused by the finish of a throttle opening restraining control is preferably suppressed. SOLUTION: When a clutch-to-clutch down-shift judgment has been performed by a down-shift judgment deciding means 106, the drop of an engaging pressure of a relief side hydraulic friction engaging device is suppressed by a relief side hydraulic pressure drop suppressing and controlling means 110 until the finish of the throttle opening limiting control is decided by a throttle opening limiting control finish judgment means 104. Consequently, an engaging torque is not insufficient even when a turbine torque T T has returned at the finishing time of the throttle opening limiting control, and the engaging torque in clutch-to-clutch down-shifting is smoothly continued in the state that the turbine torque T T (=T IN ) is stable. As a result, the generation of a shock caused by the finish of the throttle opening restraining control is preferably suppressed. COPYRIGHT: (C)2004,JPO

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 shift control system for a vehicular automatic transmission that has sufficient robustness against a disturbance such as braking of a vehicle even without high precision control equipment in clutch-to-clutch downshift control during coasting travel. SOLUTION: A slight driving state controlling means 134 controls or increases engine speed NE according to an actual input/output speed difference NSLIP in a clutch-to-clutch downshift performed during coasting travel, to thus maintain a slight driving state of the vehicle during the clutch-to-clutch downshift. The clutch-to-clutch downshift control during coasting travel in that slight driving state reduces torque fluctuation to provide high hydraulic control precision of a brake B1 and a clutch C1 related to the shift, so that even without high- cost equipment with high control precision, sufficient robustness can be obtained against a disturbance such as braking of the vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a shift control device for an automatic transmission suppressing a shifting shock when shifting the transmission while lowering a vehicle speed as in coast down shifting. SOLUTION: During coast down shifting, the number of synchronous revolutions of a transmission input shaft in each speed stage after A seconds is calculated from deceleration of a vehicle. A convergence value of the numbers of transmission input shaft revolutions after A seconds is predicted, and a speed stage with the number of synchronous revolutions most approximate to the convergence value is set as "the next speed stage" to carry out coast down shifting. By this, the shifting shock during coast down shifting can be mitigated. COPYRIGHT: (C)2010,JPO&INPIT
