    摘要： A method of controlling speed changes in a hydraulically actuated type multiple-stage speed change gear, which renders it possible to prevent the occurrence of "shift hunting" without impairing the acceleration characteristics of the vehicle and also reduce the magnitude of shocks which occur at the time of speed changes even in case hydraulic clutches of small capacity are used. According to this method of controlling speed changes, a controller (30) is used to conduct speed changes when conditions for speed changes, i.e., upshift/downshift are satisfied, and in cases where a downshift is made after an upshift and an upshift is made after a downshift, speed changes are conducted after the lapse of a long speed change inhibiting time, and in other cases than the aforementioned, speed changes are conducted after the lapse of a short speed change inhibiting time. Further, only in case the vehicle is decelerated from a high speed stage to a coasting speed, deceleration operations are conducted with a direct coupled clutch (8) of the torque converter (3) kept in engaged condition, and in other cases than the aforementioned, speed changes are conducted with the direct coupled clutch kept in released condition.

    摘要： In a configuration in which electronically operated pressure control valves (31-36) are respectively connected to clutches of a two-stage transmission (3) composed of main transmissions (1st, 2nd, R, 4th, 3rd) and sub transmissions (L, H), when a downshift is effected from a present speed stage to a next speed stage with power on, the supply of oil pressure to a speed-changing clutch for the present speed stage is stopped on the basis of a speed-change command, the pressure control valve is actuated when a relative number of revolutions of the speed-changing clutch for the next speed stage becomes zero, which commences the supply of oil pressure to that speed-changing clutch, and the supply of oil pressure is gradually increased upon confirming the completion of a filling time of the speed-changing clutch. Thus discomfort owing to a speed-change shock is prevented in whatever state the amount of an accelerator operated and the state of operation of a brake are.In addition, in a downshift accompanying the operation of clutches of both transmissions, torque off time is not provided for the sub transmission clutch, and the supply of oil pressure to a next stage clutch is commenced immediately so as to supply oil pressure at a gradually increasing rate. After engagement of the clutch, the supply of oil pressure to the main transmission clutch at a gradually increasing rate is effected upon completion of the filling time, thereby preventing discomfort attributable to a speed-change shock.

    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 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.
