Abstract
A control apparatus for a four-wheel-drive vehicle is configured to determine whether or not a degree of a yaw movement for deflecting the vehicle to a left or right side is larger than a predetermined first degree. When the degree of the yaw movement is larger than the first degree, the control apparatus increases a coupling torque of a coupling device corresponding to a rear wheel at the same side as a direction of the yaw movement to a predetermined first torque value, and maintains at zero a coupling torque of a coupling device corresponding to a rear wheel at an opposite side to the direction of the yaw movement.
