Abstract:
1. An upshift control method of an automatic transmission, comprising: determining whether a predetermined control condition of a damper clutch is satisfied during an upshift under a power-off; determining whether a seriate upshift signal is detected, when the predetermined control condition is satisfied; determining whether the damper clutch is in a direct engagement state before a current upshift, when the seriate upshift signal is detected; determining whether a fuel-cut control is executed, when the damper clutch is in the direct engagement state before the current upshift; and performing a hydraulic pressure duty control for the damper clutch, on the basis of at least one control parameter, such that a shift feel is enhanced, while seriate upshifts corresponding to the seriate upshift signal are being progressed, when the fuel cut control is executed.
