Abstract

A controller of a vehicle that includes a return control unit configured to carry out a complete engagement control of a power connecting/disconnecting device. At the time a return condition from inertia traveling to normal traveling is established and a down shift of an automatic transmission is requested, the return control unit carries out a down shift control of the automatic transmission so that a difference between an increasing gradient of a rotating speed of a first engaging portion and an increasing gradient of a rotating speed of a second engaging portion is within a predetermined range. At the time it can be regarded that the rotating speed of the first engaging portion and the rotating speed of the second engaging portion are synchronized, the return control unit completely engages the power connecting/disconnecting device.
