Abstract
An up-shift control apparatus installed to an automatic transmission, where an up-shift is executed by disengaging a first friction element and by engaging a second friction element, includes an A/T control unit for deciding the up-shift, a gear ratio detecting unit for detecting a gear ratio of the automatic transmission, a discharging pressure control actuator, and an up-shift discharging pressure control unit. The up-shift discharging pressure control unit outputs a command to the discharging pressure control actuator to temporally increase the discharging pressure of the first friction element when the detected gear ratio becomes a preset gear ratio indicative of a time just before the end of the inertia phase during an up-shift.
