Beschreibung
Zusammenfassung:	A control device 10 is mounted on a four-wheel-drive vehicle 1, and includes a detector and a vibration suppression controller. The detector detects the occurrence of a vibrating state, in which drive wheels and auxiliary drive wheels slip alternately in a four-wheel-drive state in which a drive force is transferred to the auxiliary drive wheels, or the occurrence of a preliminary state for the vibrating state. The vibration suppression controller reduces the drive force which is transferred to the auxiliary drive wheels via a drive force transfer device 2 when the vibrating state or the preliminary state is detected by the detector. The vibration suppression controller reduces the drive force which is transferred to the auxiliary drive wheels on condition that a thermal load of the drive force transfer device 2 is less than a predetermined threshold.
