Stability control device of vehicle compatible with foot braking

A stability control device of a vehicle having a vehicle body, and front left, front right, rear left and rear right wheels, comprising:

• a means 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 means for selectively applying a variable braking force to each of said rear left and rear right wheels, said brake means including a manually controlled pressure source means incorporating a brake pedal and an accumulator pressure source means;
• and
• a control means for controlling said brake means according to said drift-out quantity so as variably to apply a braking force to a selected one or both of said rear left and rear right wheels for suppressing the vehicle body against drift-out,
• wherein said control means controls said brake means by employing said manually controlled pressure source means when said brake pedal is depressed equal to or more than a predetermined extent, while employing said accumulator pressure source means when said brake pedal is depressed less than said predetermined extent.
