<p><P>PROBLEM TO BE SOLVED: To provide an automatic transmission that suppresses the occurrence of a busy shift, and reduces the load of a clutch mechanism and a shift mechanism by reducing the number of gear shifts. <P>SOLUTION: The automatic transmission 1 includes a gear shift control device 80 that operates shift mechanisms 70a-70d, and when a gear shift command is transmitted, executes the gear shift control corresponding to the gear shift command by changing the engagement state of the clutch mechanism 30. When the gear shift command is transmitted, the shift control device 80 calculates a shift time Ps required for gear shift control corresponding to the gear shift command and the next command time Pn from the present time to the transmission of the next gear shift command, and waits for the execution of the gear shift control by a standby time Pw when the shift time Ps is longer than the next command time Pn. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
