<p><P>PROBLEM TO BE SOLVED: To provide a dual clutch type automatic transmission which reduces the transmission shock and stabilizes the revolutions of an engine after a gear shift by controlling the deceleration of the revolutions of the engine in upshift. <P>SOLUTION: A shift control device 80 of the dual clutch type automatic transmission 1 includes: a target transmission torque operation part 81 which the computes target transmission torque Tch of a high-speed stage side clutch 31 in upshift; an upshift controller 82 which controls the disengagement of a low-speed stage side clutch 32 and controls the high-speed stage side clutch 31 by controlling the target torque Tch of the high-speed stage side clutch 31 and controlling the synchronization of the engine speed Ne; and a deceleration suppressing torque controller 84 which suppresses the decelerationΔNe of the engine speed Ne by making the low-speed stage side clutch 32 transmit deceleration suppressing torque Tu when the decelerationΔNe of the engine speed Ne exceeds a target speed decelerationΔNet. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
