Abstract
Official abstract text for this publication.
In a control apparatus for an automatic transmission in which a read-ahead vehicle speed which is a future vehicle speed is estimated on a basis of an acceleration and an actual vehicle speed and a gear shift control is carried out on a basis of the read-ahead vehicle speed and other driving parameters, a start of an up-shift is inhibited even if a determination of the up-shift is made for a predetermined time after a down-shift in a coast state has occurred and executing the up-shift after the predetermined time is elapsed. Consequently, while an unpleasant feeling given to a driver is suppressed, an appropriate gear shift is executable.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control apparatus for an automatic transmission in which a read-ahead vehicle speed which is a future vehicle speed is estimated on a basis of an acceleration and an actual vehicle speed and a gear shift control is carried out on a basis of the read-ahead vehicle speed and other driving parameters, the control apparatus comprising a delay up-shift control means for inhibiting a start of an up-shift even if a determination of the up-shift is made for a…
