ABSTRACT:
A transfer clutch control units operates a second transfer clutch torque corresponding to a yaw moment out of the transfer clutch torque to be output to a transfer clutch drive unit by a second transfer clutch torque operational unit. The second transfer clutch torque operational unit operates a reference lateral acceleration from a lateral acceleration to be operated based on a linear vehicle motion model from a vehicle driving state and a preset coefficient according to the vehicle driving state, in addition to the yaw moment sensing the yaw rate and the yaw moment sensing the steering wheel angle, and operate the yaw moment corresponding to the deviation between the reference lateral acceleration and the actual lateral acceleration as a corrected value of the yaw moment. Not only a high μ road but also a low μ road, even abrupt change of road surfaces or the like can be consistently and optimally coped with in excellent response.
