1. A control device for a limited slip differential, which is mounted on a vehicle including a vehicle behavior control device that controls behavior of the vehicle by controlling a braking force that is applied to front and rear wheels, and the limited slip differential that is capable of limiting a differential operation of the front and rear wheels, and which controls the limited slip differential, the control device comprising:

  • a differential limiting force calculating device that calculates a target value of a differential limiting force that limits the differential operation of the front and rear wheels based on a vehicle traveling state;

    a differential limiting force correcting device that makes a correction to reduce the target value of the differential limiting force calculated by the differential limiting force calculating device, based on a command from the vehicle behavior control device; and

    a thermal load calculating device that calculates a thermal load of the limited slip differential;

    whereinthe differential limiting force correcting device limits the correction of the target value of the differential limiting force based on the command from the vehicle behavior control device, when the thermal load calculated by the thermal load calculating device is equal to or larger than a predetermined value.
