In a four-wheel-drive vehicle having auxiliary drive wheels to which power of a drive power source is transmitted via a transmission member, in which connecting/disconnecting devices are provided between the drive power source and the transmission member and between the transmission member and the auxiliary drive wheels such that one of the connecting/disconnecting devices is a friction engagement clutch while the other is a dog clutch, when switching from two-wheel-drive running mode in which both the clutches are disconnected to four-wheel-drive running mode, an acceleration/deceleration adaptive synchronization portion sets an allowable deceleration based on a vehicle acceleration/deceleration and controls an engagement torque of the friction engagement clutch to make the deceleration of the vehicle equal to the allowable deceleration when the rotation speed of the transmission member is increased.
