Patent ID: 8489294

Claim:
A transmission control device for an automatic transmission that changes the speed of rotation output from an engine having a turbocharger, the transmission control device comprising: intake-state detecting means configured to detect an intake state of the engine, wherein the intake-state detecting means detects at least one of an amount of intake air in the engine, an intake pressure of the engine, and an air-fuel ratio of the engine; intake-state determining means configured to determine whether or not a predetermined target intake state is satisfied on the basis of a detection result of the intake-state detecting means, wherein the intake-state determining means sets the target intake state on the basis of a target torque and an operating range of the engine; transmission-pattern selecting means having a first transmission pattern for setting a transmission gear ratio in accordance with an operational state and a second transmission pattern for setting the transmission gear ratio such that an engine rotation speed is higher than that in the first transmission pattern, the transmission-pattern selecting means configured to select the first transmission pattern when the target intake state is satisfied and to select the second transmission pattern when the target intake state is not satisfied; and transmission control means configured to control a transmission mechanism unit of the automatic transmission on the basis of the transmission pattern selected by the transmission-pattern selecting means.
