ABSTRACT:
A stability control device for a vehicle is shown including a device that estimates a liability of the vehicle body to a turn running instability and produces an instability quantity that generally increases along with increase of the liability. A braking device selectively applies a variable braking force to each wheel. A controller controls the braking device so as to variably apply the braking force to a selected wheel or wheels based upon the instability quantity for suppressing the vehicle body against the turn running instability. The controller withholds applying the braking force to the selected wheel or wheels when the instability quantity is discretely produced more than a threshold number of times in succession at a magnitude greater than a threshold value with an interval shorter than a threshold time duration.
