PROBLEM TO BE SOLVED: To compatibly save fuel consumption and secure driveability in a previously assumed travel pattern. SOLUTION: This shift control device for an automatic transmission comprises a means having a fuel consumption saving travel mode in which a gear-change diagram for fuel consumption saving travel, set to suppress an engine speed, is applied for travel, and a normal travel mode in which a gear-change diagram for normal travel is applied for travel, for storing a travel mode determination diagram representing a time change of a speed in a travel pattern for a predetermined fuel consumption saving travel, and a means for collating a time change of a speed after starting with the travel mode determination diagram and determining whether fuel consumption saving travel is in process or not as intended to save fuel consumption. It selects the fuel consumption saving travel mode or the normal travel mode to execute shift control depending on whether the fuel consumption saving travel is in process or not.
