摘要： A lock-up device supplies hydraulic pressure to a lock-up clutch when lock-up capacity becomes insufficient with increasing accelerator operation amount during slip control. The lock-up device (1) sets a hydraulic unit pressure command value corresponding to drive source torque so rotational speed difference becomes target slip speed when a variation in accelerator operation amount is in a predefined range, and deriving an estimated drive source output torque corresponding to the accelerator operation amount to set the pressure command value corresponding to the estimated drive source torque so the rotational speed difference becomes target slip speed when accelerator operation amount variation exceeds the range's upper limit, and (2) controls the hydraulic unit to supply hydraulic pressure corresponding to hydraulic pressure command value to the lock-up clutch.

摘要： An oil pressure command value for slip-control of a lock-up clutch of a torque converter is calculated based on a feed-forward oil pressure value calculated by an FF value calculating unit and a feed-back oil pressure value calculated by a feedback value calculating unit. When the feedback oil pressure value is calculated, a deviation out-of-range determining unit determines whether a deviation between actual rotational speed difference and target rotational speed difference is outside of a predetermined range. If the deviation is outside of the predetermined range, a feedback value correcting unit calculates a correction value and corrects the feedback oil pressure value. Therefore, when the deviation is outside of the predetermined range, the actual rotational speed difference is brought into convergence with the target rotational speed difference with rapid response. When the deviation falls within the predetermined range, normal feedback control is adopted to assure stability without overshooting, even in a high engine speed, high engine torque state.

The controller adopts a time, which one of the transmission's gear-mechanism selectors requires in shifting a current change-speed stage to another change-speed stage, as a pre-shift time for selecting the latter change-speed stage. The change-speed stage anticipator operates the one of the gear-mechanism selectors while adopting a temporary change-speed stage as a subsequent change-speed stage when the temporary change-speed stage, which is estimated from a state of vehicle after the pre-shift time, the state of vehicle being relevant to each element of an anticipated change-speed stage group that is made up of one or more of the change-speed stages that can be selected by the one of the gear-mechanism selectors being set on one of the transmission's input shafts that is disconnected from a power source, coincides with an anticipated change-speed stage that corresponds to the pre-shift time.

摘要： A transmission includes a controller that has a rapid-deceleration judge and a rapid-deceleration processor. The rapid-deceleration judge judges whether a vehicle is decelerating rapidly or not. The rapid-deceleration processor includes a torque-fluctuation inhibitor, and an after-rapid-deceleration change-speed stage anticipator. The torque-fluctuation inhibitor shuts off power transmission from a power source, or holds power transmission by way of a current change-speed stage or lower, when the vehicle is decelerating rapidly. The after-rapid-deceleration change-speed stage anticipator anticipates a subsequent change-speed stage being adapted for restarting or reaccelerating the vehicle that has come out of rapid deceleration.
