METHOD FOR CONTROLLING AND DEVICE FOR CONTROLLING AUTOMATIC TRANSMISSION

摘要

The present invention is provided with: a transmission control unit that calculates a target transmission gear ratio on the basis of vehicle state, and controls a control value by outputting an instruction value in a manner so that the actual transmission gear ratio tracks the target transmission gear ratio; a transmission-gear-ratio-fluctuation prediction unit that predicts the occurrence of fluctuations in the actual transmission gear ratio when it has been detected or inferred that the amount of change per unit time in the control value of an infinitely variable transmission is greater than the amount of change per unit time in the instruction value; and a transmission-gear-ratio-fluctuation suppression unit that executes control suppressing fluctuations in the actual transmission gear ratio when fluctuations in the actual transmission gear ratio have been detected by the transmission-gear-ratio-fluctuation prediction unit.
