A vehicle stability control device for reducing and/or canceling a yaw moment owing to the imbalance in longitudinal forces between the left and right wheels of the vehicle by automatically steering wheels. The control device estimates a longitudinal force difference-caused yaw moment and a vertical load shift-caused yaw moment exerted on the vehicle body. A steering apparatus is operated to apply on the vehicle body a counter yaw moment obtained by eliminating a contribution of the vertical load shift-caused yaw moment from a counter yaw moment calculated from the longitudinal force difference-caused yaw moment.
