Abstract
A system and method of vehicle stability enhancement control the method comprising the steps of determining a Delta Velocity of the vehicle, determining one of an understeer and an oversteer condition of the vehicle, applying a percentage of the Delta Velocity to an outside front and an outside rear wheel in the oversteer condition, and applying a percentage of the Delta Velocity to an inside front and an inside rear wheel in the understeer condition. The system and method may further comprise the step of applying the Delta Velocity to a rear wheel during the oversteer condition or applying the Delta Velocity to a front wheel during the understeer condition using fluid pressure from a master cylinder when braking is occurring.
