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

    【課題】低温環境下であっても、非駆動状態から車輪の駆動を開始する場合における摩擦係合装置の応答性を適切に確保することができる車両用駆動伝達装置の制御装置を提供する。【解決手段】駆動力源に駆動連結された入力軸Iと、車輪に駆動連結された出力軸Oと、入力軸Iと出力軸Oとを結ぶ動力伝達経路に設けられた摩擦係合装置と、を備えた車両用駆動伝達装置を制御対象とする制御装置であって、摩擦係合装置の温度To,Tfを示す温度情報を取得する温度取得部と、摩擦係合装置の係合の状態を制御する係合制御部と、を備え、係合制御部は、入力軸Iが回転状態、且つ、出力軸Oが停止状態で、温度情報に示される温度To,Tfが規定の閾値TH1,TH2以下の場合に、摩擦係合装置を滑り係合状態とする滑り制御を実行する。【選択図】図3
