Claim:
1. A vehicle stabilization system comprising: a vehicle driving stability control device configured to have a braking device generate a braking force to reduce rotation of wheels and performing an anti-lock braking control when a vehicle is braked; and a yawing moment cancelling device for cancelling a yawing moment applied to the vehicle, wherein the vehicle driving stability control device estimates a friction coefficient of a friction material for braking the wheels, calculates braking forces for the left and right wheels using the estimated friction coefficient, calculates a yawing moment applied to the vehicle based on a braking force difference between a left wheel braking force to reduce rotation of the left wheels and a right wheel braking force to reduce rotation of the right wheels and determines an operation amount on the yawing moment cancelling device, wherein if the braking force difference is larger than a predetermined threshold value, the vehicle driving stability control device determines that a driving road of the vehicle is a split μ road and operates the yawing moment cancelling device by the operation amount, and wherein the vehicle driving stability control device estimates the friction coefficient of the friction material for braking the wheels based on a brake fluid pressure supplied to the braking device and a front-rear direction acceleration of the vehicle using a function corresponding to the predetermined correlation of the friction coefficient of the friction material for braking the wheels with the brake fluid pressure supplied to the braking device and the front-rear direction acceleration of the vehicle.
