Shift control apparatus and method for automatic transmission |
摘要 |
<p>A shift control apparatus includes an automatic transmission provided with a first friction-engagement element and a second friction-engagement element; and a friction-engagement element control section configured to control the first and second friction-engagement elements. The friction-engagement element control section includes a target-value setting section configured to set a first target differential speed; a first control section configured to bring a rotational speed difference of the first friction-engagement element gradually close to the first target differential speed; and a second control section. The second control section includes a torque-capacity calculating section configured to calculate a total transfer-torque capacity, and a distribution ratio setting section configured to set a distribution ratio between transfer-torque capacities of the first and second friction-engagement elements. The second control section sets transfer-torque capacities of the first and second friction-engagement elements on the basis of the calculated total transfer-torque capacity and the set distribution ratio, and adjusts each of engagement-control parameters for the first and second friction-engagement elements in accordance with the set transfer-torque capacities of the first and second friction-engagement elements.</p> |
