Abstract
A four-wheel drive vehicle includes an engine, a transmission provided on a power transmission path between a main drive wheel and a subsidiary drive wheel, and a connection-disconnection mechanism provided on a power transmission path between the transmission and the subsidiary drive wheel to selectively connect and disconnect the power transmission path. A control device for the four-wheel drive vehicle includes an electronic control unit. The electronic control unit is configured to control a transmission torque of the transmission to be less than or equal to a predetermined value when a predetermined condition is satisfied during traveling, and to control the connection-disconnection mechanism so as to at least partially overlap a time during which the transmission torque of the transmission is controlled to be less than or equal to the predetermined value and a time during which the power transmission path is disconnected by the connection-disconnection mechanism.
