<P>PROBLEM TO BE SOLVED: To provide a warm-up control device of a transmission capable of improving efficiency of fuel consumption or the like while minimizing the operation of the transmission during cold time by controlling so as to efficiently perform warm-up of the transmission when a vehicle is parked. <P>SOLUTION: The warm-up control device 1 performs warm-up of a multi-stage automatic transmission 10. When the vehicle is parked, the warm-up control device performs the control for engaging a second clutch C2 for a high speed stage, that is different from a first clutch C1 for forming a first speed stage as a start moving speed stage, as a warm-up operation on the automatic transmission 10. Thus, friction heat generated inside the automatic transmission 10 by differential rotation of the second clutch C2 rises oil temperature of operation oil inside the automatic transmission 10. Therefore, the automatic transmission 10 can be warmed up without waiting for the engine to be warmed up, which is different from warming up of the automatic transmission 10 with coolant water of the engine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
