Zusammenfassung:Control device for a 4WD vehicle is provided. The 4WD vehicle includes a driving force source, main driving wheels, auxiliary driving wheels, a driving force transmission shaft, a first disconnection mechanism, and a second disconnection mechanism. The first disconnection mechanism and the second disconnection mechanism are engaged during 4WD traveling. One of the first disconnection mechanism and the second disconnection mechanism is a clutch. The control device includes an electronic control unit. The electronic control unit is configured to execute engagement control for controlling the engagement force of the clutch so that the driving force transmission shaft is maintained in a state prior to the initiation of a continuous increase in the rotation speed of the driving force transmission shaft.
