A part time four-wheel-drive vehicle includes a first driving force transmission system and a second driving force transmission system. A control device controls the second driving force transmission system. The control device includes a road surface state determination section (S19) that determines whether a coefficient of friction of a road surface is equal to or higher than a predetermined value based on an index value regarding the coefficient of friction of the road surface, controls a dog clutch such that the dog clutch is engaged irrespective of the index value regarding the coefficient of friction of the road surface (S11) when an ignition switch is brought into the on-state (S10), and when the ignition switch is in the on state, the control device controls the dog clutch such that the dog clutch is brought into the disengaged state (S21) when it is determined that the coefficient of friction of the road surface is equal to or higher than the predetermined value S(19). |
