    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 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.

    摘要： The present invention is concerned with a transmission constructed in the two-staged structure including main speed changing units (1st, 2nd) and auxiliary speed changing units (H, L) which are provided with clutches (H, L 1st, 2nd) which in turn are individually connected to electronic type pressure control valves (21 and 24) so as to enable the respective clutches to be controlled separately. When it is found that pressurized hydraulic oil delivered from a hydraulic pump has a shortage in amount at the time of starting of forward movement of a vehicle, feeding of hydraulic oil to the clutches (H, L) on the main speed changing unit side and the clutches (1st, 2nd) on the auxiliary speed changing unit side is effected with a certain time difference kept therebetween in order to suppress fluctuation in filling time due to reduction of an amount of hydraulic oil delivered from the hydraulic pump.

    摘要： During shift change, a discrimination is made as to a load, a quantity of residual hydraulic oil in respective shift change clutches (F, R, 1 to 4) and a state of shift change which has been effected from what speed stage to what speed stage so that a pattern of electrical commands to be issued to pressure control valves (51 to 56) for required shift change clutches is variably controlled depending on results derived from the above discrimination. Thus, smooth shift change can always be achieved regardless of running conditions. Electrical commands (C.sub.1 to C.sub.6) to be fed to the respective pressure control valves (51 to 56) are compared with electrical currents (I.sub.1 to I.sub.6) outputted from drive circuits and outputs (S.sub.1 to S.sub.6) from clutch pressure detecting means (101 to 106) for each clutch, whereby an abnormality is detected with the relevant clutch based on results derived from the comparison. Once an abnormality is detected, an adequate disposal for processing the abnormality is executed so as to reliably prevent double engagement from taking place with clutches.

    摘要： A method for controlling a transmission system mounted on such as a traveling machine or a construction machine, the transmission system having a two-stage clutch configuration in which a speed is selected through a combination of a plurality of sub transmission clutches and a plurality of main transmission clutches. At the time of speed change, engagement is started beginning with the main transmission clutch side, and the engagement of the sub transmission clutch is commenced upon completion of the filling of the oil in the main transmission clutch, thereby reducing the two speed-change shocks, including a reverse shock, which are conventionally experienced.
