The invention provides a power train control device which can inhibit displacement of an AWD vehicle when the vehicle returns from automatic neutral control. The power train control device (1) includes: an input clutch (31) that adjusts driving force transmitted from an engine (20) to a transmission mechanism (33) constituting an automatic transmission (30); a transfer clutch (41) that adjusts driving force transmitted from the transmission mechanism constituting to a driving system component which drives driven-wheels (10RL, 10RL); an input clutch control unit (71) that releases the input clutch (31) if predetermined automatic neutral control conditions are satisfied; and a transfer clutch control unit (72) that controls engaging force of the transfer clutch (41) based on a running state of the AWD vehicle (4) equipped with the power train control device. When returning from automatic neutral control, the transfer clutch (41) control unit temporarily releases and then re-engages the transfer clutch (41), during a period from start to completion of engaging of the input clutch (31).
