1. A control apparatus for an all-wheel drive vehicle that includes (i) front wheels, (ii) rear wheels, (iii) a power source, (iv) a power distribution device configured to distribute a power from the power source to the front wheels and the rear wheels, (v) a differential limiting mechanism configured to place the power distribution device in a differential limiting state in which a rotational difference between the front wheels and the rear wheels is limited, and (vi) a braking device configured to apply a wheel braking torque to each of the front wheels and the rear wheels, the control apparatus comprising:
circuitry configured to, when the power distribution device is placed in the differential limiting state and the wheel braking torque is applied to each of the front wheels and the rear wheels, execute a torque limiting control for setting an upper limit value of a torque of the power source to a smaller value when the wheel braking torque is large than when the wheel braking torque is small.
