摘要： An automatic transmission control apparatus has first and second hydraulic servos for engaging forward and reverse driving friction engaging elements, respectively, a fluid pressure control unit, a range shift detector, and an electronic control unit. When the forward driving range is selected, the fluid pressure control unit supplies a forward driving range pressure to the hydraulic servo via a changeover valve operated by a signal pressure from a normal open-type solenoid valve, when the signal pressure is drained. When the reverse driving range is selected, the electronic control unit outputs a signal to magnetize the solenoid valve. The solenoid valve is thus turned on to discontinue the drain. The control apparatus thus prevents low pressure in the reverse driving range pressure to prevent delay of engagement of the clutch.

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： 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.

摘要： In a multiple speed-change operation for switching between an up-shift operation and a down-shift operation, engine torque control is adapted to an actual change in speed-change state, whereby an abrupt change in rotational speed of the input shaft is prevented. One embodiment relates to a speed-change operation from the second speed to the third speed, wherein the engagement-side hydraulic pressure B4 rises and the release-side hydraulic pressure B5 drops, the rotational speed NT of the input shaft changes from a second speed state toward a third speed state and the engine torque TE is reduced by a predetermined amount TCU. If a command to perform a speed-change operation from the third speed to the second speed is issued during the aforementioned speed-change operation from the second speed to the third speed, control of the hydraulic pressures is switched to the speed-change operation from the third speed to the second speed. If it is detected because of the hydraulic pressure control that the direction of the change &ohgr; in rotational speed of the input shaft has changed toward the second speed, it is determined that the speed-change operation has actually started. Then, the torque reduction operation is suspended, and the torque is gradually restored.

摘要： In a driven state, a hydraulic pressure of disengagement side is set at a stroke pressure, a one-way clutch in an operating state is over-run, an engine rotation speed is in an idle state, and an automatic transmission is in a neutral state. In a drive state, the hydraulic pressure of disengagement side is controlled so that a difference between an engine rotation speed and an input rotation speed reaches a difference between the both rotation speeds at a start of the shift control. In a state of a synchronized rotation after the shift, the hydraulic pressure of disengagement side is controlled so that the input rotation reaches the synchronized rotation.

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： A learning controller makes learning correction based on a time tST between start of a shift control routine and detection of start of a change in rotational speed of the transmission input shaft and further based on the amount of rotational speed change &ohgr;S′ at the detected start of the rotational speed change. When the time tST is longer than a basic time and when the rotational change amount &ohgr;S′ is too large, it is determined that a servo piston has not been sufficiently advanced and the shift control is corrected so that the time tST is lengthened. When the time tST to the detected start of the rotational speed change &ohgr;S′ is too small, it is determined that, while the piston has been advanced properly, the target engagement pressure PTA in torque phase control is too low because of a miscalculation, and the shift control is corrected so that the target engagement pressure is raised.

摘要： The control system for a linear solenoid valve controls output of an oil pressure according to a current value to be fed to the linear solenoid which operates the linear solenoid valve. A solenoid current monitor detects the current value fed to the linear solenoid and an IG voltage monitor detects the voltage level of the battery. A linear solenoid current value setting unit sets a target current value according to a target oil pressure level and a duty ratio setting unit sets a duty ratio for applying the battery voltage to the linear solenoid on the basis of signals coming from the current monitor, the voltage monitor and the current value setting unit. A solenoid driver applies the battery voltage to the linear solenoid for a predetermined period in accordance with the duty ratio set by the duty ratio setting unit. The duty ratio setting unit, in turn, includes: a feedback correction unit for feedback correction of the duty ratio, in accordance with the difference between the current value detected by the monitor and the target current value set by the current value setting unit, so that the current value fed to the linear solenoid approaches the target current value; and a voltage correction unit for further correcting the duty ratio, as previously corrected by the feedback correction unit, on the basis of the voltage level of the battery, as detected by the voltage monitor.

摘要： A shift control apparatus has first, second, third and fourth engagement elements, and a shift control processing unit engaging the first and the second engagement elements in order to realize a first shift speed, engaging the third and the fourth engagement in order to realize a second shift speed, and inhibiting an increase in torque capacity of one of the first and second engagement elements before starting of release of the second engagement element when shifting from the first to the second shift speed. During shifting from the first to the second shift speed, an increase in torque capacity of one of the first and second engagement elements is inhibited before starting of release of the second engagement element. This prevents a step-like shift shock from being caused by the slowed progression of shifting when release of the second engagement element is started.
