<P>PROBLEM TO BE SOLVED: To increase the temperature of a transmission lubricant when it is low, in a power transmission controller for a vehicle using a double clutch transmission. <P>SOLUTION: In a selection system, a selection clutch is controlled to an engaged state while a "selected gear shift stage" is established in a selection mechanism part. In a non-selection system, a non-selection clutch is controlled to a disengaged state while a "higher adjacent gear shift stage" or a "lower adjacent gear shift stage" is established in a non-selection mechanism part. When the temperature of the transmission lubricant is equal to or higher than a predetermined value, in the non-selection mechanism part, a gear shift stage is established based on a prediction result as to which of shift-up and shift-down is performed next among the "higher adjacent gear shift stage" or the "lower gear shift stage". Meanwhile, when the temperature of the transmission lubricant is lower than the predetermined value, in the non-selection mechanism part, the "lower adjacent gear shift stage" is forcibly established without depending on the prediction result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
