Zusammenfassung:A method of controlling an electric power steering system of a vehicle is provided. The method determines that one or more hand wheel torque sensors of the vehicle are not enabled. The method generates an assist torque command by estimating a lateral acceleration of the vehicle based on a hand wheel angle and determining an amount of assist torque based on the estimated lateral acceleration. The method controls the electric power steering system using the generated assist torque command.
