| Abstract | When failure occurs in an electric component of an electric power steering (EPS) system, measures are taken to stop assist control. After the failure occurs, EPS results in no assist. In such a case, the driver must steer the vehicle by torque only, which places a burden on the driver. In order to alleviate this burden, we have developed EPS assist control for a failure in which only one of the three phases is unable to supply power to a motor in the brushless motor EPS. |
