A vehicle stability control system includes a base required driving force
calculation unit, an estimated driving force estimation unit, and a
required driving force correction unit. The base required driving force
calculation unit calculates a physical quantity to generate the base
required driving force at a driving wheel. The estimated driving force
estimation unit estimates a driving force as being generated in the
vehicle. The required driving force correction unit obtains a correction
to suppress a potential pitching vibration in the vehicle. The physical
quantity calculated by the base required driving force calculation unit
is corrected on the basis of the correction. The corrected required
driving force obtained by the required driving force correction unit is
generated at the driving wheel.
