    摘要： A four-wheel-drive vehicle includes a clutch that is able to allow and interrupt transmission of driving force to a propeller shaft, and a traction control unit that controls at least one of the driving force generated by an engine and braking force applied to right and left front wheels to suppress a slip of the right and left front wheels. When the drive mode is switched from a two-wheel-drive mode to a four-wheel-drive mode, if the relative rotational speed between a first rotary member and a second rotary member constituting a clutch is equal to or higher than a predetermined value, an ECU outputs a control command signal for suppressing the slip of the right and left front wheels to the traction control unit.
