A shift output torque control unit executes a shift output torque control to control an engine torque so as to reduce a driving force difference, which is a variation width of a driving force due to downshift of an automatic transmission. Thus, in comparison with the case in which the shift output torque control is not executed, it is possible to smooth a variation in driving force associated with the downshift. As a result, occupants' comfort and controllability to driving operation may be improved.
