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 systemare 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.

    本文描述的技术解决方案包括一种控制电动助力转向系统的方法,该方法包括:确定电动助力转向系统的一个或多个手轮扭矩传感器处于不运行,并且作为响应,通过基于电动助力转向系统的马达的马达角度和车辆速度估计前滑移角来生成辅助扭矩命令。该方法还包括将前滑移角转换成齿条力。该方法还包括基于齿条力来确定辅助扭矩量,以及使用所生成的辅助扭矩命令来控制电动助力转向系统。
