ABSTRACT:
An automatic transmission shift control apparatus includes a shift point learning-correcting unit and a high acceleration time upshifting unit. The shift point learning-correcting unit executes learning-correction of a shift point during an upshift such that an input rotational speed of the automatic transmission reaches a predetermined target maximum rotational speed. The high acceleration time upshifting unit executes, when predetermined high acceleration is requested, an upshift control based on the shift point in which a learning value of the shift point learning-correcting unit is reflected. When the high acceleration is not requested, the upshift control is performed based on a reference value of the shift point in which the learning value of the shift point learning-correcting unit is not reflected. The shift point learning-correcting unit executes the learning-correction of the shift point when the learning value is reflected in the upshift control.
