Patent ID: 7625313

Claim:
In a vehicular automatic transmission that establishes a plurality of gear steps of different gear ratios by selectively engaging a plurality of engagement elements, a shift control device of a vehicular automatic transmission that performs a coast downshift by engagement switch between a release-side engagement element and an engagement-side engagement element at a time of deceleration of a vehicle, comprising: a deceleration intention determination device that determines whether or not there is a driver's intention to decelerate the vehicle during the coast downshift; a shift wait device that stops a rise of an engagement pressure of the engagement-side engagement element so as to cause the coast downshift not to progress, if the deceleration intention determination device makes an affirmative determination; and a shift progress device that raises again the engagement pressure of the engagement-side engagement element so as to cause the coast downshift to progress, if the deceleration intention determination device makes a negative determination while the rise of the engagement pressure has been stopped by the shift wait device.
