Abstract
A power-on 2-3 upshift control method for an automatic transmission comprises: determining whether a power-on 2-3 upshift condition exists; extracting an initial hydraulic pressure control duty and hydraulic pressure control duty depending on an input torque from a map table for an on-coming friction element and an off-going friction element, if it is determined that the power-on 2-3 upshift condition exists, and performing a shift control for the upshift; and completely releasing a hydraulic pressure of the off-going friction element at a point at which a hydraulic pressure for the on-coming friction element is capable of tolerating a turbine torque.
