    Abstract: A shift control system for an automatic is designed to prevent engine racing and clutch tie-up during a clutch-to-clutch shift (clutch switching shift) involving engagement/disengagement of first and second frictional engagement elements. The shift control system includes an engagement force controller for independently controlling both of the frictional engagement elements. A gear ratio calculator continuously calculates a gear ratio r of the transmission and a shift characteristic value calculator calculates a shift characteristic value .alpha. based on changes in the gear ratio between the start of the shift and completion of the shift. A control value calculator calculates a control value .beta., based on the shift characteristic value .alpha. calculated by the shift characteristic value calculator and a shift characteristic value .alpha.I on an ideal gear ratio curve. The control value .beta. is calculated so that the shift characteristic value .alpha. coincides with the shift characteristic value .alpha.I on the ideal gear ratio curve.

    Abstract: 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 100 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 100 on values of these parameters.

    Abstract: An R-N-D control valve of a hydraulic control system is disclosed which ensures the prevention of shock that may occur at the time of an "N-R" and an "N-D" manual shift, by unifying a shift control pressure with one valve in the case of an "N-R" shift and an "N-D" shift and first-second speed shift. The present invention discloses that a line pressure generated from a manual valve is changed to a control pressure controlled by the proportional control of a linear valve, and transmitted to each clutch and brake according to the movement position of a spool of a valve by the line pressure.
