    • A control system for an automatic transmission, which receives the rotation of the engine through a fluid coupling, and which has a clutch applied when a forward running range is selected and released when a neutral range is selected and a range selecting mechanism for selecting a range. The control system includes a range detector for detecting the selected range, a hydraulic circuit and a control unit. The hydraulic circuit includes a hydraulic servo which is fed an oil pressure for applying the clutch and a manual valve movable between at least a forward range position for generating a forward range oil pressure and a neutral range position, by operation of the range selecting mechanism. A regulator valve regulates the forward range oil pressure to generate a regulated oil pressure. A solenoid valve is turned ON/OFF by the control unit to generate a signal oil pressure for switching a change-over valve between a first position feeding the forward range oil pressure to the hydraulic servo and a second position feeding the regulated oil pressure to the hydraulic servo. The control unit delays output of the signal solenoid valve, if a switching from the forward running range to the neutral range is detected by the range detector, so that the change-over valve remains in the second position until lapse of a set time period, and is then moved to a first position after the set time period has elapsed.

    • A control system for control of a clutch interposed between a fluid transmission unit and a speed change unit in a vehicular automatic transmission. The control system includes a first R.P.M. detector for detecting clutch input side R.P.M. and a second R.P.M. detector for detecting clutch output side R.P.M. A stop state detector determines if the vehicle is at a standstill and a starting operation detector detects a starting operation by the driver. The hydraulic control unit includes a hydraulic servo for applying/releasing the input clutch, a control signal oil pressure generating solenoid valve for generating a control signal oil pressure, a control valve for regulating a forward running range pressure according to the control signal oil pressure to generate a control oil pressure; a change signal oil pressure generating solenoid valve for generating a change signal oil pressure and a change-over valve switchable by the change signal oil pressure, between a first position in which it feeds the forward running range pressure to the hydraulic servo, and a second position in which it feeds the control oil pressure to the hydraulic servo. A failure is decided if the clutch input/output R.P.M. difference is over a set value which is set on the basis of the clutch input/output R.P.M. difference when the starting operation is detected by the starting operation detector. A fail-safe feature causes a shift output to a higher speed gear stage, over-riding a control signal from the pressure booster, when a failure is decided, to output the change signal to the solenoid of the control signal oil pressure solenoid valve to thereby bring the change-over valve into the first position.

    • When a vehicle is halted with the transmission in a forward drive range, an input clutch is disengaged to enhance the fuel efficiency and, at the same times a hill-hold brake is engaged to prevent the vehicle from rolling backward on a steep up-slope. At that time, the hydraulic pressure P.sub.C-1 of the input clutch C1 is gradually reduced by .DELTA.P.sub.CIR (P.sub.C-1 =P.sub.C-1 -.DELTA.P.sub.CIR) while the hydraulic pressure P.sub.B-1 of the hill-hold brake B1 is increased gradually so as to satisfy an equation P.sub.B-1 =K1+K2 X e where .DELTA.P.sub.cir is a change in hydraulic pressure which is required for gradually disengaging the first clutch C1, K1 is a hill-hold brake pressure at which braking resistance begins, K2 is hill-hold brake pressure producing a fully braked condition, and e is the input/output rotational-speed ratio of a torque converter Subsequently during start of vehicle movement, the hydraulic pressure P.sub.C-1 of the input clutch C1 is gradually increased (P.sub.C-1 =p.sub.C-1 +.DELTA.P.sub.C-1A) while the hydraulic pressure P.sub.B-1 of the hill-hold brake B1 is gradually decreased (P.sub.B-1 ==P.sub.B-1-.DELTA.P.sub.B-1) until the ratio of the rotational speed N.sub.C-1 of the first clutch C1 becomes less than a rotational speed N.sub.C-1E corresponding to the clutch being almost engaged .DELTA.P.sub.C-1A and .DELTA.P.sub.B-1 are incremental values proportional to accelerator depression so that a delay in starting is reduced in accordance with driver demand.
