Provided is a device that protects a clutch while causing as little loss of torque transmission performance as possible. A hydraulic clutch for power distribution is arranged between a power source and an auxiliary drive wheel, command torque is determined in accordance with the travel state, and hydraulic pressure corresponding to the command torque is supplied to the hydraulic clutch. The surface temperature of the clutch is estimated (detected), a limiting value is generated for limiting the command torque when the differential rotation of the input/output shaft of the clutch is equal to or greater than a predetermined value and the command torque is equal to or greater than a predetermined value, and control is performed so that the limiting value is increased together with an increase in the surface temperature of the clutch. |
