A control method for a stability control device in a vehicle is provided to maintain a posture control of the vehicle more stably by detecting a driving road condition of each wheel more simply and more accurately. A control method for a stability control device in a vehicle includes an inlet valve of normal open type at an entrance of each wheel cylinder, an outlet valve of normal close type at an exit. A pressing pump supplies pressed fluid to each wheel cylinder(S101). A motor operates the pressing pump. A break pressures is controlled by controlling the motor and the inlet valve and the outlet valve. The brake pressure of each wheel cylinder is increased and decreased by detecting increasing and decreasing rate of wheel speed of each wheel, then estimating a driving road condition of each wheel according to the detected wheel speed increasing and decreasing rate of each wheel(S105). |
