摘要： The present invention prevents shift shock and reduces time required to execute the complete speed change operation in the case where a second speed change is commanded while a first speed change operation is still in progress. If a down-shift to a first speed stage is commanded during an up-shift operation from the first to the second speed, the hydraulic pressure in the second speed change operation is controlled in accordance with the state of the first speed change operation at the time of generation of the command for the second speed change. For example, if a down-shift to the first speed stage is commanded during the torque phase of an up-shift operation from first to second speeds, namely, before change in the rotational speed of the input shaft has started, only completion control of the down-shift operation is executed. On the other hand, if the down-shift to the first speed stage is commanded during the inertia phase of the up-shift operation, namely, after the speed change has been started, hydraulic control of the down-shift is started with the initial speed change control.
摘要翻译： 本发明在第一变速操作仍在进行中，在第二变速指令的情况下，能够防止变速冲击，并减少执行完全变速操作所需的时间。 如果在从第一速度到第二速度的升档操作期间指令到第一速度档位的下降，则根据第二变速操作中的第一变速操作的状态来控制第二变速操作中的液压 生成第二速变化命令的时间。 例如，如果在从第一速度到第二速度的升档操作的扭矩阶段期间，即在输入轴的转速的变化已经开始之前指令到第一速度级的下降，则仅完成控制 执行降档操作。 另一方面，如果在升档操作的惯性阶段（即在变速开始之后）指令到第一速度级的下降，则下降的液压控制开始于初始 变速控制。

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.

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： If a shift to the 3rd speed is decided during the 5th-4th speed shift, in which the hydraulic servo for a second clutch is released by pressure regulation control, a changeover valve is switched by a solenoid valve so that the fluid pressure P.sub.C2 from the pressure regulating valve is conducted to a third clutch hydraulic servo. Thereby, the third clutch hydraulic servo pressure P.sub.C3 stands by at a predetermined engaging pressure P.sub.H and, at the same time, the servo-start of a fourth brake fluid pressure P.sub.B4 is performed by another pressure regulating valve. Meanwhile, the fluid pressure P.sub.C2 is released by an accumulator. After the servo-start ends and the 4th speed is established, the 4-3 speed shift control is performed, thus preventing shift shock and reducing shift duration.

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： A control apparatus executes appropriate speed change control under any operating conditions encountered during an up-shift by change-over, without requiring an increase in control logic. Engagement side hydraulic pressure is swept up as a result of an arithmetic operation in torque phase speed change control. Disengagement side hydraulic pressure is calculated by initial speed change control, dependent on the engagement side hydraulic pressure. The engagement side hydraulic pressure is directly controlled and the disengagement side hydraulic pressure is indirectly controlled, i.e. responsive to the engagement side control. Consequently, the same control scheme can be executed regardless of power-on state or power-off state and regardless of vehicle operating conditions.

摘要： A control system for an automatic transmission includes: an input clutch applied, responsive to selection of a forward running range, to transmit the rotation of an engine to a transmission mechanism; a hydraulic servo for selectively applying/releasing the input clutch; a stop state detector for detecting a stop state of a vehicle in terms of the selection of the forward running range, lack of vehicle speed, the release of an accelerator pedal and the depression of a brake pedal; starting operation detector for detecting an operation to start the vehicle in motion; application state detector for detecting the application state of the input clutch; and a controller for controlling oil pressure fed to the hydraulic servo on the basis of signals coming from the various detectors. If arrival at a predetermined released state is decided, the hydraulic servo is fed with a summed oil pressure which is the total of an initial application oil pressure and a release oil pressure, to initiate piston movement and start of engagement of the input clutch, and the oil pressure is thereafter gradually raised from the summed pressure on the basis of a predetermined pressure relationship. If a failure to arrive at the predetermined released state is decided, the oil pressure is gradually raised on the basis of the predetermined pressure relationship from the oil pressure which is fed to the hydraulic servo when a starting operation is detected.

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： The automatic transmission of the present invention prevents fluctuation of torque transmission through a band brake. In the hydraulic operator for the band brake, a resilient elastic cushion is provided between a rod abutting one end of the band of the band brake and a piston. Any slippage between the band and drum of the band brake will result in oscillation of the rod. However, the elastic cushion absorbs oscillation of the rod, thereby isolating the piston from that oscillation.

摘要： When a shift to a second gear ratio (second ratio) is determined during a shift control for a first shift (shift from fourth ratio to third ratio), the process status, or circumstances, of the first shift is determined using a hydraulic pressure for a fourth brake being engaged at the determination. When the process status, that is, the process circumstances, is in early phase, the first shift is interrupted and shift control for the direct shift to the second ratio (shift from fourth ratio to second ratio) is performed (first shift pattern). When the process status is in a late phase, the first shift control is continued, and after ending of the first shift control, the control for the shift to the second gear ratio (shift from third ratio to second ratio) is performed (second shift pattern). In the case of power off state, the second shift pattern is performed irrespective of the process status.
