摘要： A device with a stepped automatic transmission to transfer power from a power source to an axle using changeable shift speeds includes an input-side fluid transmission element connected to the power source, an output-side fluid transmission element connected to the transmission input shaft, a lock-up clutch engaging and disengaging the input-side and the output-side fluid transmission elements; a unit adjusting the lock-up clutch; a unit setting, when a downshift is to be performed in response to a predetermined request for a large drive force, a predetermined target slip speed value larger than a non-shifting-time value before a rotational speed of the power source exceeds a input shaft rotational speed after the downshift, and setting the target slip speed to decrease toward the non-shifting-time value along with lapse of time after the power source rotational speed source exceeds the post-shifting input shaft speed; and a unit controlling the engagement force so the slip speed becomes the set target slip speed. The target slip speed is a difference between the rotational speeds of the power source and the input shaft, and the non-shifting-time value is set when no shifting is performed.

摘要： ECU executes in-neutral control in a case where a first clutch is brought into a half-engagement state on the basis of execution of neutral control. During the in-neutral control, ECU detects engine speed and input-shaft rotating speed, and detects differential rotation before an oil pressure change. Subsequently, in a case where the differential rotation before an oil pressure change detected by ECU has exceeded a first differential rotation threshold value, the operating oil pressure for a hydraulic servo is reduced by the first oil pressure.

摘要： Quick shifting is achieved while preventing a shift shock when shifting is caused by grip change of four engagement elements. The automatic transmission requires activation of the four engagement elements when shifting from a first shifting position (sixth speed) to a second shifting position (third speed) is performed. This shifting control apparatus includes shift control means for starting disengagement of a second engagement element after starting disengagement of a first engagement element; completing engagement of a fourth engagement element after completing engagement of a third engagement element; and starting disengagement of the second engagement element before completing engagement of the third engagement element.

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： 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 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 which includes a fluid transmission unit. The control system includes a clutch applied in a forward running range; a hydraulic servo for applying the clutch responsive to an oil pressure; input and output R.P.M. sensors for detecting the input and output R.P.M.s of the fluid transmission unit; a stop state detector for detecting that the vehicle is stopped; a start detector for detecting start of the vehicle from a stop; and a control unit for controlling the oil pressure fed to the hydraulic servo. The oil pressure of the hydraulic servo is reduced, when the vehicle is stopped, to establish a neutral control state in which the clutch is released. A completely applied state of the clutch is established by boosting the oil pressure fed to the hydraulic servo when the shift of the vehicle from a stop to start is detected, in two stages. In the first stage the oil pressure fed to the hydraulic servo is boosted by adding a set shelf pressure to the base pressure until the clutch comes into a partially applied state and then, in the second stage, the oil pressure fed to the hydraulic servo is further boosted until the clutch becomes completely applied.

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.
