To provide a controller for a vehicle drive transmission device that is capable of properly securing responsiveness of a frictional engagement device when starting driving of wheels from a non-driven state even in a low temperature environment.SOLUTION: A controller is used for controlling a vehicle drive transmission device comprising: an input shaft I coupled to a drive force source for driving; an output shaft O coupled to wheels for driving; and a frictional engagement device which is provided on a power transmission path connecting the input shaft I and the output shaft O. The controller comprises: a temperature acquisition unit for acquiring temperature information indicating temperatures To, Tf of the frictional engagement device; and an engagement control unit for controlling a state of engagement of the frictional engagement device. The engagement control unit executes slip control for placing the frictional engagement device in a slip engagement state when the input shaft I is in a rotating state, the output shaft O is in a stopped state, and the temperatures To, Tf indicated by the temperature information are equal to or less than prescribed thresholds TH1, TH2, respectively.SELECTED DRAWING: Figure 3
