<p>PROBLEM TO BE SOLVED: To provide a shift control method for an automatic transmission capable of restraining shift hunting by a transfer between an ordinary shift pattern and a speed reduction time shift pattern as much as possible. SOLUTION: In this shift control method of the automatic transmission for shifting according to a shift pattern by switching the ordinary shift pattern for shifting on the basis of a vehicle speed V and throttle openingθand the speed reduction time shift pattern for shifting on the basis of a vehicle speed reduction state according to the throttle openingθaccording to a vehicle traveling state, when the throttle openingθbecomes first opening 01 or less, the vehicle traveling state is switched to the speed reduction time shift pattern from the ordinary shift pattern, and when the throttle openingθbecomes second openingθ2 or more larger than the first openingθ1, the vehicle traveling state is switched to the ordinary shift pattern from the speed reduction time shift pattern.</p> |
