摘要：An automatic transmission control device of a vehicle performs a gear changeoperation based on a deceleration of the vehicle. The automatic transmission controldevice detects the deceleration of the vehicle and an engine rotational speed. The devicealso stores a peak value of the engine rotation speed during a period in which a vehicle
travels with one predetermined gear step, and includes a relationship map showing therelationship between the deceleration and a shift-down rotational speed. The deviceperforms an automatic shift-down when the engine rotational speed is lowered from thepeak value by a predetermined rotational speed which is obtained from the map basedon the deceleration.
