    摘要： PROBLEM TO BE SOLVED: To optimally adopt, stably with excellent response, not only to a high μ road but also to a low μ road and also even to an abrupt change of a road surface.
    SOLUTION: In a transfer clutch control part 30, a second transfer clutch torque according to a yaw moment among transfer clutch torques outputted to a transfer clutch drive part 40 is calculated by a second transfer clutch torque calculation part 32. A second transfer clutch torque calculation part 32 calculates, in addition to the yaw moment in response to a yaw rate and the yaw moment in response to a steering wheel angle, a reference lateral acceleration by using a lateral acceleration calculated by using the operating state of a vehicle based on a linear vehicle motion model and a coefficient pre-set according to the operating state of the vehicle, and calculates a yaw moment according to a deviation between the reference lateral acceleration and an actual lateral acceleration as the corrected value of the yaw moment.
