Title:
クラッチの制御装置
Document Type and Number:
Japanese Patent JP5266843
Kind Code:
B2
Abstract:
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.
