    摘要: The invention relates to a shift control apparatus for an automatic transmission, that executes a torque reduction control when the transmission executes a second downshift in response to a second downshift determination made during first downshift. The shift control apparatus includes a multiple shift execution unit that starts the second downshift operation in response to the second downshift determination, and a torque reduction control execution unit that executes a torque reduction control when the rotational speed of the input member is increased to at least a predetermined first determination speed, which is determined in accordance with a shift ratio of a gear stage after the second downshift operation, after the second downshift starts. This allows the rotational speed of the input shaft to be quickly changed to the appropriate synchronous rotational speed. Thus, the desired driving force is provided upon completion of the second downshift without overspeeding the engine.

    摘要: When a downshift instruction has been detected, the oil pressure of a lookup clutch is controlled, and the state of operation of the automatic transmission is detected. If a starting condition has been met, a slip rotation speed of the lockup clutch is calculated, and if the calculated slip rotation speed is greater than or equal to a reference rotation speed, the calculated slip rotation speed is set as a target slip rotation speed. If a condition for converging the target slip rotation speed has been met, the target slip rotation speed is then converged to a steady target rotation speed.

    摘要: When it is decided that it is impossible to shift the automatic transmission directly to the target speed position according to the second shifting-action decision made during a shifting control to shift the automatic transmission to a target speed according to a first shifting-action decision, one of a plurality of candidate intermediate speed positions to which the automatic transmission can be shifted directly is determined as an intermediate speed position. The determined intermediate speed position is established with the largest amount of change of an engine speed NE, and accordingly with the longest time required for completion of the change of the engine speed NE during which a hydraulic pressure of a clutch to be engaged to establish the intermediate speed position can be raised, whereby the clutch engaging pressure can be changed at a rate low enough to reduce a shifting shock of the automatic transmission.

    摘要: A shift control device of a vehicular automatic transmission, if during a first shift in a power-off state, a second shift judgment for a second shift that is a power-on downshift is made, performs a second shift control of lowering an input shaft rotation speed to a synchronous rotation speed of a post-second shift gear step through an engagement control of the friction engagement devices, and when the second shift is performed, performs a control of reducing a throttle valve opening degree of the engine to a predetermined degree that causes the engine to output a torque that is able to bring the input shaft rotation speed to a rotation speed that is higher than the synchronous rotation speed of the post-second shift gear step. The control device also executes a retardation control of retarding an ignition timing of the engine when the input shaft rotation speed is dropped through the second shift control.

    摘要: A shift control apparatus for a vehicular automatic transmission provided with a fuel cut apparatus which cuts off fuel supplied to an engine when an engine speed exceeds a predetermined value during deceleration of a vehicle, and an automatic transmission in which a gear shift is achieved with a clutch-to-clutch downshift in which a hydraulic friction device to be released is released and a hydraulic friction device to be applied is applied, further includes a controller. The controller corrects, through learning control, an apply pressure of at least one of the hydraulic friction devices to be operated for the clutch-to-clutch downshift such that an amount of drop in a rotational speed of an input shaft of the automatic transmission decreases when that amount of drop exceeds a predetermined value during the clutch-to-clutch downshift.
