    摘要: An ECT torque controlling system sets a torque demand amount. The torque demand amount set by the ECT torque controlling system is converted by a converter of a power train manager into a torque demand amount changing with a delay relative to the set torque demand amount. A selector of the power train manager switches between a state of converting the set torque demand amount into the torque demand amount changing with the delay relative to the set target value and a non-conversion state. An engine controlling system controls an engine so as to achieve the torque demand amount.

    摘要: When vehicle speed after determining that a downshift is to be performed is equal to or smaller than first permission vehicle speed VON or second permission vehicle speed VOFF, a controller of an ECT_ECU controls an automatic transmission so that the downshift is performed. When the vehicle speed after determining that the downshift is to be performed is larger than first permission vehicle speed VON or second permission vehicle speed VOFF, a first inhibitor inhibits the downshift.

    摘要: A shift control device of a vehicular automatic transmission that establishes a plurality of gear steps of different speed change ratios by selectively engaging a plurality of friction engagement devices ends the shift control by making an engagement end determination regarding an engagement-side friction engagement device if it has been determined continuously for a predetermined time that the input shaft rotation speed of the automatic transmission is in the vicinity of the synchronous rotation speed of the post-shift gear step. The predetermined time is set at a first time if the downshift is a power-on downshift due to a shift judgement in a power-on state, and is set at a second time that is shorter than the first time if the downshift is a power-off→on downshift selected in connection with a change to the power-on state during a power-off shift due to the shift judgment in a power-off state.

    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: In a shift control device and a shift control method of an automatic transmission that establishes a plurality of gear steps of different speed change ratios by selectively engaging a plurality of friction engagement devices, one of a shift start time point and an inertia phase start time point is used as a reference time. In a power-off shift, the shift action is compulsorily ended when the elapsed time from the reference time exceeds a first time. In a power-on shift, the shift action is compulsorily ended when the elapsed time from the reference time exceeds a second time that is set shorter than the first time. If a switch from the power-off shift to the power-on shift occurs halfway through the power-off shift, the shift action is compulsorily ended when the elapsed time from the time point of the switch exceeds a predetermined time.
