Beschreibung
Zusammenfassung:	A control device of a vehicle including a multi-speed automatic transmission includes a first engagement control portion selecting a selected gear shift position having a synchronous rotation speed lower than an actual input rotation speed of the multi-speed automatic transmission at the time of return from the coasting running due to the depressing operation of the accelerator pedal and increasing an engagement force of an engagement element establishing the selected gear shift position to immediately increase a drive force of the vehicle; and a second engagement control portion engaging the engagement element establishing the target gear shift position when the actual input rotation speed of the multi-speed automatic transmission reaches a determination rotation speed set for determination of attainment to the synchronous rotation speed of the target gear shift position.
