Abstract
A stability control device for a vehicle is shown that estimates a liability of a vehicle body to drift-out in order to produce a drift-out quantity that generally increases along with the increase of the drift-out liability. A brake device selectively applies a variable braking force to each wheel, with the brake device including a manually controlled pressure source having a brake pedal and an accumulator pressure source. A controller controls the brake device according to the drift-out quantity so as to variably apply a braking force to a selected wheel for suppressing the vehicle body against drifting out. The controller controls the brake device by employing the manually controlled pressure source when the brake pedal is substantially stepped on, while employing the accumulator pressure source when the brake pedal is not substantially stepped on. The use of the manually controlled pressure source may also be conditioned upon a friction coefficient of a road surface not being greater than a predetermined threshold value.
