This disclosure relates to a control device for all-wheel-drive vehicles. While ensuring power performance in a differential limiting state of the power distribution device, it suppresses a decrease in the durability of the power transmission path on the front wheels. When the power distribution device is set to a differential limiting state and wheel braking torque is applied to both the front and rear wheels, torque limiting control is performed, setting the upper limit of the power source torque to a smaller value when the wheel braking torque is high compared to when the wheel braking torque is low. Therefore, for example, when a large accelerator and a large brake operation are performed in the differential limiting state of the power distribution device, it is easier to limit the torque of the power source, so it is less likely to transmit high torque to the power transmission path on the front wheels. Furthermore, for example, when the braking operation gradually decreases while the accelerator operation gradually increases in the differential limiting state of the power distribution device, the torque limitation of the power source is gradually released, so the torque of the power source increases when the rear wheels are less prone to slight slippage.
