To improve vehicle stability by starting control based on quicker detection of the possibility that a vehicle state will reach an unstable region. It is detected that a vehicle is in a pre-skid state that is the state prior to when the vehicle reaches an unstable region where skid occurs, and brake force is generated in a rear wheel at an outside of a turn when the pre-skid state is detected. As a result of generating this brake force, load applied to the wheels at the outside of the turn increases and lateral force of the vehicle increases. Thus, it is possible to make it more difficult for skid of the vehicle to occur, and so it is possible to inhibit, in advance, gentle deterioration in vehicle behavior such as slow spin. Accordingly, the possibility that a vehicle state has reached an unstable region can be detected earlier.
