Abstract
A transmission control device controls a CVT installed in a vehicle. The device has, as modes for the CVT, a CVT mode Mfor changing a transmission gear ratio steplessly based on the operating state of the vehicle, and a stepped transmission mode Mfor changing the transmission gear ratio stepwise based on the operating state of the vehicle. The device includes a transmission mode switching control unit (controller)for controlling switching between the CVT mode Mand the stepped transmission mode Mbased on an actual accelerator opening. The transmission mode switching control unit (controller)performs switching from the CVT mode Mto the stepped transmission mode M, if the actual accelerator opening reaches or exceeds a first threshold value Tset in a plurality of stages so as to increase stepwise in accordance with an increase in a vehicle speed.
