ABSTRACT:
A stability control device of a vehicle has a unit for estimating a liability of the vehicle body to spin for producing a spin quantity which generally increases along with increase of the spin liability; a unit for estimating a liability of the vehicle body to drift-out for producing a drift-out quantity which generally increases along with increase of the drift-out liability; a brake for selectively applying a variable braking force to each of wheels; and a control unit for controlling the brake so as to apply a variable braking force to a selected one or ones of the wheels for suppressing the vehicle body against spin and/or drift-out when the vehicle is driven along a curved course, wherein the control unit controls the brake such that a first braking force is applied to one of the front wheels located at the outside of turn of the vehicle along the curved course according to an increase of the spin quantity, and a second braking force is applied to at least one of the rear wheels according to an increase of the drift-out quantity, the first braking force being decreased according to a simultaneous application of the second braking force to the at least one rear wheel.
