摘要： A control system for an automatic transmission operates a clutch in a speed change unit to disconnect a transmission mechanism from a fluid transmission unit during a neutral operating state while the vehicle in a forward gear is held stopped by braking with the throttle fully closed. Reengagement of the clutch such as by depression of accelerator pedal (throttle open), release of the brake pedal, etc., is produced by a gradual increase in oil pressure to the servo operating the clutch to prevent clutch application shock. Wear on the clutch is reduced by abrupt increase of the oil pressure in response to satisfaction of a clutch engagement completion condition based upon input RPM, output RPM and the gear ratio of the target gear. In one embodiment, this abrupt increase occurs immediately after satisfaction of the clutch engagement completion condition when the throttle is open but occurs after elapse of a set time period from satisfaction of the clutch engagement completion condition when the throttle is closed. In a second embodiment when the throttle is closed, an application standby condition based on the input RPM, the output RPM and the gear ratio indicating backward vehicle movement is determined after the clutch engagement completion condition is satisfied. If backward movement is indicated, the abrupt increase in oil pressure is made after a set time period, otherwise the abrupt increase occurs immediately. In a third embodiment, a second clutch engagement completion condition requirement is substituted for the delay of the set time period of the second embodiment to prevent application shock during the clutch engagement.

摘要： An automatic transmission includes a plurality of power transmitting gear trains making up a combination of forward power transmitting paths that can be selected one at a time, a plurality of frictional engaging elements for selecting one of the forward power transmitting paths at a time, and a one-way clutch for establishing a lowest-speed gear position among the forward power transmitting paths. When a gear shift is to be made from a neutral gear range to a forward gear range, one of the frictional engaging elements which is mechanically coupled to the one-way clutch is preliminarily engaged. When the gear shift can be made from the neutral gear range to the forward gear range, one of the frictional engaging elements for establishing the starting gear position starts being engaged, and thereafter those frictional engaging elements which are not necessary to establish the starting gear position are released. Because the frictional engaging element is mechanically coupled to the one-way clutch is preliminarily engaged, vibrations produced upon rotation of the one-way clutch are reliably suppressed when the gear shift is made from the neutral gear range to the forward gear range.

摘要： A working fluid pressure control system for an automatic power transmission includes a pre-charge pressure regulating mechanism for temporarily elevating a working fluid pressure abruptly and subsequently drop the working fluid pressure for generating a pre-charging constant pressure for a start-up friction element, and a detecting portion for detecting an operational range before selection of neutral range. When selection is made from neutral range to a traveling range, and the traveling range is different from the operational range before selection of the neutral range, the pre-charge pressure regulating mechanism is actuated when judgement is made that the start-up friction element engaged in the operational range before selection of neutral range is released, thus selection being performed within a short period without accompanying with a shock.

摘要： An automatic transmission control apparatus has a clutch, a hydraulic servo for the clutch, a fluid pressure control unit, a range shift detector, and an electronic control unit. The fluid pressure control unit has a manual valve, a pressure regulating valve device, and a changeover valve device. The electronic control unit controls the changeover valve device and the pressure regulating valve device. Immediately after a shift to the forward driving range, the electronic control unit holds the changeover valve device in such a state that a forward driving range pressure is supplied without passing through the pressure regulating valve device. Then, the electronic control unit shifts the changeover valve device to such a state that a regulated pressure is supplied from the pressure regulating valve device, which has been switched to a pressure regulating state by the electronic control unit. This control operation precisely sets the fluid pressure changeover timing and the initial fluid pressure.

摘要： A control system for an automatic transmission, has a fluid transmission unit for transmitting the rotation of an engine to a speed change unit; a clutch adapted to be applied when a forward running range is selected to transmit the rotation of the fluid transmission unit to the transmission mechanism of the speed change unit; a stopped state detector for detecting a stopped state of a vehicle wherein the stopped state is defined as a forward running range being selected, the throttle opening being fully closed, the brake pedal being depressed, and the vehicle speed being substantially zero; engine speed detector for detecting the engine speed; clutch operation force generating means for generating the application force of the clutch; and a control unit. The control unit releases the clutch by reducing the engaging force of the clutch when the stopped state of the vehicle is detected by the stopped state detecting means. The engine RPM when the clutch is released is stored as an initial engine RPM in storage means so that a neutral ending engine RPM is set on the basis of the initial engine RPM. The clutch is applied by strengthening its application force if the stopped state of the vehicle is not detected when the clutch is released and if the engine RPM exceeds the neutral ending engine RPM.
