摘要： A plurality of clutch hydraulic pressure gradual increase patterns for maintaining jerk value at a level of a target value are previously determined in dependence on vehicle weight and speed stages; a clutch hydraulic pressure gradual increase pattern corresponding to the vehicle weight and speed stage selected at the time of speed change is selected from the aforesaid plurality of clutch hydraulic pressure gradual increases patterns. Then, hydraulic pressure in a speed change clutch to be engaged is caused to increase gradually in accordance with the thus selected clutch hydraulic pressure gradual increase pattern.At the time point when a speed change command is issued, a speed change clutch to be subsequently brought in the engaged state is fed with hydraulic oil and gradually increasing hydraulic pressure is exerted on the speed change clutch after the time point when termination of filling time is confirmed with respect to this speed change clutch. Further, at this time point hydraulic pressure in the speed change clutch which is now brought in the engaged state decreased.

摘要： A lock-up clutch by way of which input/output shafts of a torque converter are operatively connected to each other is connected to an electronic type pressure control valve. During speed changing in a transmission, the problem of interruption of torque transmission can be solved by turning off the lock-up clutch at the time when filling of one of the speed changing clutches to be next brought into an operatively engaged state with hydraulic oil is completed. Hydraulic pressure (P.sub.t) in the torque converter is exerted on the back pressure portion of a piston of the lock-up clutch while hydraulic pressure (P.sub.t) in the torque converter is exerted on the proportional solenoid side of the pressure control valve, making it possible to reduce the initial hydraulic pressure. During speed changing, the lock-up clutch is not fully released from the engaged state but maintains its operative state at low pressure, causing shock from shifting the lock-up state to be reduced. When hydraulic pressure is gradually increased, the extent of opening the throttle, weight of the vehicle and the current gear ratio are derived so as to vary the rate of gradual increase of hydraulic pressure depending on values of these parameters.
