Zusammenfassung:A method and system for controlling vehicle stability may comprise determining whether a vehicle is oversteering or understeering and, if the vehicle is oversteering or understeering, determining an amount by which to reduce a speed of the vehicle to correct for understeering or oversteering and applying brake pressure to at least the rear brakes of the vehicle to reduce vehicle speed. The method and system also may comprise determining an engine torque reduction amount based on vehicle oversteer or understeer conditions, reducing engine torque by the determined amount or to zero if the determined amount of engine torque reduction is greater than an actual engine torque, and applying braking to at least the rear brakes of the vehicle if the determined amount of engine torque reduction is greater than the actual engine torque.
