摘要： A control system for an automatic transmission includes a fluid transmission unit connected to an engine; a clutch; a hydraulic servo; output RPM detector for detecting the output RPM of the fluid transmission unit; oil pressure generator for generating the oil pressure fed to the hydraulic servo; and a control unit. The control unit includes a booster for raising the oil pressure according to preset characteristics; change rate detector for detecting the RPM change rate of the output RPM in a preset range at the application of the clutch; and a corrector for correcting the preset characteristics by comparing the detected RPM change rate and a reference RPM change rate. The change rate detector detects the RPM change rate only when the output RPM at the time of starting the engagement of the clutch is higher by a preset value than the maximum of the output RPM in the preset range.

摘要： In a disengagement side control, in a power on state, a disengagement side pressure P.sub.W is output, P.sub.W being set higher than a base pressure dependent on input torque, and a disengagement side frictional engagement element is engaged and maintained. In a power off state, a disengagement side pressure lower than the base pressure is output, and the disengagement side frictional engagement element slips. In the disengagement side control, when the vehicle driving state is changed from the power off state to the power on state, the disengagement side pressure P.sub.W is changed from that for a slip state to that for a maintain state.

摘要： An transmission control unit includes a sensor for detecting a vehicle condition, a traffic condition monitor for determining whether or not traffic is heavy, a transmission pattern selector, and a transmission controller. The traffic condition monitor adds or subtracts a predetermined value in response to vehicle speed detected at set intervals of time so as to provide a vehicle speed value. The heavier the traffic, the larger the additional value. Also, the lighter the traffic, the larger the subtractive value. The vehicle traffic value is used in order to determine how heavy the traffic is.

摘要： 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.

摘要： A control system for an automatic transmission operates a clutch for disengaging a transmission mechanism when a vehicle is stopped and idling with the brake pedal depressed while the gear shift is in a forward gear. The clutch is maintained at a drag state (friction elements disengaged but oil causing some torque transmission) bordering a slip state (friction elements engaged) When a neutral control is started, the clutch is released until the retraction of the piston of the hydraulic servo is started. When the rate of change in a rotational difference does not exceeds a reference rate of change even after a set time has elapsed, booster means of specific release state holding means decides that the clutch is in a drag region, and raises an oil pressure to be fed to the hydraulic servo, by a set pressure. On the other hand, when the rate of change exceeds the reference rate and the rotational difference increases, irrespective of the lapse of a set time, the first pressure reducing means of the specific release state holding means decides that the clutch is in a slip region, and lowers the oil pressure to be fed to the hydraulic servo, by a set pressure. As a result, the clutch is always held in a state which is immediately before the transfer from the drag region to the slip region.

摘要： A hydraulic pressure control apparatus for an automatic transmission including a microprocessor-based control unit for controlling hydraulic pressure supplied to hydraulic servos of friction engagement elements. The control apparatus calculates a target hydraulic pressure P.sub.TA for a condition at the start of the inertia phase in accordance with the input torque, and a gradient based on the target hydraulic pressure and a predetermined time t.sub.TA. A first up-sweep of hydraulic pressure is performed by the apparatus with the gradient. A relatively gradual gradient .delta.P.sub.TA is set based on a target rotation change rate for the input rotational speed to provide a predetermined change amount when the hydraulic pressure becomes the target hydraulic pressure P.sub.TA. The control apparatus performs a second up-sweep with the gradient .delta.P.sub.TA. When the rotational speed change .DELTA.N of the input rotation becomes a rotation change start-determining rotational speed dN.sub.S, the control apparatus feedback-controls the hydraulic pressure with a predetermined gradient while referring to the input rotation change. Further, the control apparatus detects the target shift start time and the rotational speed change rate at the target shift start time to correct the target hydraulic pressure P.sub.TA, the gradient .delta.P.sub.TA of the second sweep section, and the target shift start time t.sub.aim.

摘要： 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.

摘要： An automatic transmission control apparatus has an input clutch, a hydraulic servo for the clutch, a fluid temperature detector, an engine start detector, a range shift detector, and a control device for controlling the fluid pressure supply to the hydraulic servo. The control device raises the fluid pressure supply to the hydraulic servo on the basis of predetermined rising characteristics in normal operation. When it is determined that the shift has been performed for the first time since the start of the engine and it is determined that the fluid temperature is lower than a predetermined temperature, the control device rapidly raises the fluid pressure supply to the hydraulic servo up to the required engaging pressure.
