Abstract
The present invention provides a transmission control device for a vehicle capable of changing a threshold of a shift map for determining shift-up, thereby preventing occurrence of the shift-up during depression of an accelerator and preventing occurrence of a torque interruption. In a transmission control device for a vehicleincluding a T/M-ECUwhich automatically performs shift control for switching a plurality of shift gears of a transmissionfor shift-up or shift-down, the T/M-ECUhas a shift threshold setting unitwhich sets a shift threshold to be used for the shift control, on the basis of an operation plan or a surrounding state of the vehicle, and the shift threshold setting unitsets the shift threshold to perform the shift control on the transmissionso as not to perform the shift-up of the transmissionduring acceleration of the vehicle
