摘要： A method of controlling a direct-coupling mechanism of hydraulic power transmission device of an automatic transmission for an automotive vehicle, wherein the transmission capacity of the direct-coupling mechanism is controlled such that the valve of a predetermined parameter indicative of an amount of relative slip between input and output members of the hydraulic power transmission device which are mechanically engaged with each other by the direct-coupling mechanism lies within a predetermined reference range. The predetermined parameter value is detected and the detected value is compared with the predetermined reference range. A desired value of the predetermined reference range and a predetermined period of time are determined on the basis of the comparison result. The transmission capacity is controlled to the determined desired value for the determined predetermined period of time. The transmission capacity is maintained so long as the detected predetermined parameter value lies within the predetermined reference range. At least first and second transmission capacity increasing regions are provided which correspond to larger values of the amount of relative slip than that the predetermined reference range corresponds to, wherein the first region is closer to the predetermined reference range than the second region is. A rate of increase of the transmission capacity in the first region is set to a value smaller than that in the second region. A fine-control region is provided adjacent at least one of extreme limits of the predetermined reference range, wherein the transmission capacity is finely adjusted toward the predetermined reference range.

摘要： An automatic transmission has lower side and higher side friction engagement devices, with the lower side one being engaged and the higher side one being disengaged when a lower speed stage is engaged, while the lower side one is disengaged and the higher side one is engaged when the speed stage one higher than that lower speed stage is engaged. A control device for the transmission includes a shift valve for switching actuating fluid pressure between the lower side and the higher side friction engagement device and for draining the other one thereof, to provide the lower or the higher speed stage. An upshift smoothing valve is interposed in the drain path for the lower side friction engagement device for providing a higher flow resistance when a value representing engine output is relatively high and for providing a lower flow resistance when the value representing engine output is relatively low. Thus upshifting shock is reduced, particularly under low engine output conditions, in which overlapping of the engagement of the lower side and the higher side friction engagement devices is reduced. Optionally, the upshift smoothing valve may provide its higher or lower flow resistance, according as to whether the value representing engine output prevails over the actuating pressure for the higher stage friction engagement device, in a relationship between them, or not.

摘要： An automatic transmission includes a mechanical transmission mechanism coupled to a fluid coupling such as a torque converter. The mechanical transmission mechanism has several power trains and several friction engagement mechanisms. By selective supply of actuating fluid pressure to selective ones of the friction engagement mechanisms, various speed stages are provided. A control system for this transmission includes an assembly for producing a signal representative of engine output, an anti creep device for varying the actuating hydraulic fluid pressure for a one of the friction engagement mechanisms which is engaged for providing the lowest speed stage, according to the signal representative of engine output, from a low value when engine output is low upward as engine output increases, and can include an assembly for inhibiting the action of the anti creep device so as to cause that actuating hydraulic fluid pressure for that one of the friction engagement mechanisms to be at its high value when the mechanical transmission mechanism is providing one of its speed stages higher than the lowest speed stage. Also, the control system can include a manually controllable assembly for, when so desired, inhibiting the action of the anti creep device so as to cause the actuating hydraulic fluid pressure for that one of the friction engagement mechanisms to be at its unaltered value.

The control system includes a first sensor for detecting the value of a first parameter indicative of the engine load, and a control mechanism adapted to compare the value of the first parameter detected by the first sensor with a predetermined reference value for selectively engaging and disengaging the input and output members with and from each other through the direct-coupling mechanism. A second sensor detects the value of a second parameter indicative of the vehicle speed, and a reference value setting device sets the predetermined reference value to a value dependent on the value of the second parameter detected by the second sensor.
