Abstract
A control apparatus for a four-wheel-drive vehicle is configured to, during braking of the vehicle in a two-wheel-drive state, determine whether or not a degree of a yaw movement for deflecting the vehicle 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 first coupling torque of a first coupling device and a second coupling torque of a second coupling device to a predetermined first torque value which is larger than zero, and controls a ground contact load adjusting device in such a manner that a first ground contact load at a rear wheel at an outer side with respect to the yaw movement becomes larger than a second ground contact load at a rear wheel at an inner side with respect to the yaw movement by a predetermined first load difference or more.
