<p>A shift control device for an automatic transmission, wherein a shelf pressure control means increases the coupling pressure of the friction elements at a first gradient preset based on the output of a shift command, outputs a torque-down command to a torque-down control means when an inertia phase start is detected after a shift command is output, raises a shelf pressure at a second gradient set for each shift stage using as an initial shelf pressure a coupling pressure at an inertia phase detection time, adds a torque variation-equivalent oil pressure only when a variation in throttle opening is detected, and outputs a torque-down terminating command to the torque-down control means when the termination of an inertia phase is detected after an inertia phase starts. Accordingly, it is possible to properly set a shelf pressure in an inertia phase without requiring an enormous amount of data despite a change in throttle opening.</p> |
