<P>PROBLEM TO BE SOLVED: To provide a transmission control device for an automatic transmission that suppresses a reduction in fuel efficiency and improves the state of exhaust gas. <P>SOLUTION: The transmission control device 250 for an automatic transmission 200 for changing speed of rotation output from an engine 10 having a turbocaburetter 20 includes: an intake-state detecting means 33 for detecting an engine intake state; an intake-state determining means 100 for determining, based on the detection result of the intake-state detecting means, whether a predetermined target intake-state is satisfied; a transmission-pattern selecting means 250 having a first transmission pattern for setting a transmission gear ratio according to an operational state and a second transmission pattern for setting a transmission gear ratio so that an engine rotation speed is higher than that in the first transmission pattern, and selecting the first transmission pattern when the target intake-state is satisfied, and the second transmission pattern when not; and a transmission control means for controlling the transmission mechanism unit of the automatic transmission based on the transmission pattern selected by the transmission pattern selecting means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
