PURPOSE:To prevent a tack-in phenomenon in a turning state by conducting as the decrease of a stability factor the setting and the numerical value prediction of tack-in strength at the time of an accelerator being OFF during high speed turning, operating a yaw moment and area differential limit torque that are for preventing the decrease, and controlling a rear wheel differential limit device. CONSTITUTION:At the time of an accelerator being OFF during high speed turning, tack-in strength is predicted at a tack-in strength predicting portion 52 according to the state of turning, and this prediction is numerically valued and set as the decrease of a stability factor. A yaw moment and rear differential limit torque that are for preventing this stability factor decrease, are operated by means of respective operation portions 53, 54, and the torque of the rear wheel differential limit device is controlled. As a result, at the time of the accelerator being OFF, a proper yaw moment is generated at a vehicle due to the brake force difference of inner wheels and outer wheels, and tack-in is prevented accurately and surely. As a result, a sense of incongruity and vehicle behavior change at the time of reacceleration is reduced.
