  "textContent": "Technical solutions described herein include a method of controlling an electric power steering system includes determining that one or more hand wheel torque sensors of electric power steering system are not operational and in response generating an assist torque command by estimating a front slip angle based on a motor angle of a motor of the electric power steering system and a vehicle speed. The method also includes converting the front slip angle to a rack force. The method also includes determining an amount of assist torque based on the rack force and controlling the electric power steering system using the generated assist torque command.",
