An all-wheel-drive-vehicle controller includes: a drive gear coupled to a driving source; a driven gear meshed with the drive gear and coupled to main and sub driving-wheel axle shafts transmitting torques to main and sub driving wheels, respectively; a transfer clutch interposed between the driven gear and the sub-driving-wheel axle shaft and adjusting the torque transmitted to the sub driving wheel; a first determination unit determining whether a first condition in which a torque applied to the drive gear is substantially zero is satisfied; a second determination unit determining whether a second condition in which hydraulic pressure is applied to the transfer clutch and a torque applied to the driven gear is substantially zero is satisfied; and a control unit controlling a torque adjuster to adjust the torque applied to either one of the drive gear and the driven gear if the first and second conditions are satisfied.
