A stability control device of a vehicle having an estimator for identifying a tendency of the vehicle body toward running instability when, for example, the vehicle is making a turn, and for producing an instability quantity which generally increases along with increase of the tendency; a first wheel speed detector of an inside wheel, with respect to the duration of turn, for producing an inside wheel speed signal; a second wheel speed detector of an outside wheel for producing an outside wheel speed signal; a brake for selectively applying a variable braking force to each of the wheels; and a controller for controlling the brake so as variably to apply a braking force to the outside wheel according to calculations based upon the instability quantity and the inside wheel speed signal, wherein the controller uses the outside wheel speed signal as a substitute for the inside wheel speed signal when the inside wheel speed signal is judged to be abnormal, and further, when the outside wheel speed signal is judged to be abnormal, the controller holds the braking force applied to the outside wheel constant for a predetermined period before terminating the control operation.
