A system correcting for a traction steer event includes a steering wheel angle entered into a steering wheel angle function to identify a steering wheel angle gain. A steering wheel velocity is entered into a steering wheel velocity function to identify a steering wheel velocity gain. A vehicle speed is entered into a vehicle speed function to identify a vehicle speed gain. A propulsion motor torque is entered into a motor torque function to identify a propulsion motor torque gain. A vehicle yaw rate is entered into a yaw rate function to identify a yaw rate gain. The gains are all multiplied to obtain a final gain. The final gain is submitted to a control module which determines a steering torque overlay required to adjust a torque output from an electric power steering motor.
