<p>PROBLEM TO BE SOLVED: To provide an automatic transmission device allowing the accurate transmission of power following accelerating operation. SOLUTION: The automatic transmission device comprises an automatic clutch 20, an automatic transmission 30 and an ECU 50. The automatic clutch 20 has a friction clutch 21 and a clutch actuator 23 for actuating the opening and engagement of the clutch 21. The automatic transmission 30 has shift actuators 41-43 for actuating the change-over of gear stages. The ECU 50 drives the clutch actuator 23 and the shift actuators 41-43 depending on vehicle driving conditions to control the automatic, clutch 20 and the automatic transmission 30. When an acceleration pedal 14 is operated and engine torque is at a negative value, the ECU 50 maintains the gear stage in the automatic transmission 30 and drives the clutch actuator 23 for slipping the clutch 21.</p> |
