Abstract
A vehicle gear-shifting control apparatus is equipped with an engine, an automatic transmission, and a controller which changes a shift stage by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft to the automatic transmission. The controller executes a torque-regulating control of temporarily increasing or decreasing an input torque input to the input shaft during a shift-change, and when executing the control, determines whether or not a target increase/decrease amount of the input torque can be realized based on calculation results of a target output torque and a target gear-shifting time, executes the control to realize the target amount when it is determined that the target amount can be realized, and executes the control based on an allowable gear-shifting time set in advance to be longer than the target gear-shifting time when it is determined that the target amount cannot be realized.
