摘要： A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo. A signal pressure is applied to the regulator valve to establish a predetermined gear stage by switching the applied/released states of the first frictional engagement element and the second frictional engagement element by feeding/releasing oil pressure to/from the first hydraulic servo and the second hydraulic servo. The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.

摘要： A control system in an automatic transmission for controlling the change-over of the three speed change patterns which are a speed change pattern having a cross gear ratio on a low speed side, a speed change pattern having a cross gear ratio on a high speed side and a speed change pattern having a normal gear ratio. According to this controlling system, when one of the three speed change pattern is selected based one a throttle opening and a vehicle speed, and when it is judged that the gear shift from a speed range in the present speed change pattern to a speed range in the selected speed change pattern falls under on of prohibited conditions, e.g., requiring engagement and/or disengagement of three or more frictional engaging elements for the gear shift, the gear shift is performed using a temporary speed change pattern (including the present speed change pattern) including a speed range not falling under the prohibited conditions. Thereafter, the pattern selection is repeated and the change-over between speed change pattern is performed under a gear shift condition not falling under the prohibited conditions.

摘要： At the time of the 6→3 speed shift, an automatic transmission achieves a 6→4→3 speed shift by controlling the servo pressures of four engageable elements. A control apparatus controls the servo pressure of one engageable element in accordance with the servo pressures of other engageable elements. The engagement and release timings are adjusted by determining and controlling the oil pressures of the hydraulic servos, taking into consideration the 6→4 shift state (torque sharing) during a shift transitional period. Therefore, engine blow and prolongation are prevented during the 6→3 shift control.

摘要： A control system for an automatic transmission includes: a clutch adapted to be applied when a forward running range is selected, to transmit the rotation of an engine to the transmission mechanism of a speed change unit and a hydraulic servo for applying/releasing the clutch. A control unit controls oil pressure fed to the hydraulic servo and includes: an application starting pressure detector for detecting application starting pressure at the instant when the application of the clutch is started; an initial application pressure setter for setting an initial application pressure on the basis of the detected application starting pressure; and an oil pressure regulator for adjusting the oil pressure fed to the hydraulic servo, when a change is made to a forward running range, and then gradually raising that oil pressure. The application starting pressure detected by the application starting pressure detector is the value at which the application of the clutch is actually started, so that the initial application pressure can be properly set even if the actual oil pressure fed to the hydraulic servo regardless of the urging force of a return spring or variation in manufacture of the hydraulic control system.

摘要： A control system for an automatic transmission includes: an input clutch applied, responsive to selection of a forward running range, to transmit the rotation of an engine to a transmission mechanism; a hydraulic servo for selectively applying/releasing the input clutch; a stop state detector for detecting a stop state of a vehicle in terms of the selection of the forward running range, lack of vehicle speed, the release of an accelerator pedal and the depression of a brake pedal; starting operation detector for detecting an operation to start the vehicle in motion; application state detector for detecting the application state of the input clutch; and a controller for controlling oil pressure fed to the hydraulic servo on the basis of signals coming from the various detectors. If arrival at a predetermined released state is decided, the hydraulic servo is fed with a summed oil pressure which is the total of an initial application oil pressure and a release oil pressure, to initiate piston movement and start of engagement of the input clutch, and the oil pressure is thereafter gradually raised from the summed pressure on the basis of a predetermined pressure relationship. If a failure to arrive at the predetermined released state is decided, the oil pressure is gradually raised on the basis of the predetermined pressure relationship from the oil pressure which is fed to the hydraulic servo when a starting operation is detected.

摘要： The invention eliminates the feeling of two-phase speed-change operations by causing a speed-change operation to proceed continuously when the speed-change operation is performed through two-phase control of engagement and release of four engagement elements. An automatic transmission is such that a predetermined speed-change operation is achieved through a pre-phase speed-change operation in which a first engagement element and a third engagement element are released and engaged respectively and through a post-phase speed-change operation in which a second engagement element and a fourth engagement element are released and engaged respectively. A control apparatus has a torque control capability for adjusting an input torque of a transmission during the pre-phase speed-change control, and ensures continuous changes in the input speed during the pre-phase and post-phase speed-change operations through adjustment of the input torque (torque reduction) to prevent bluntness from being caused between the pre-phase and post-phase speed-change operations.
