    • A microcomputer (an electric current command value calculating section) carries out field weakening control in which a d-axis electric current command value Id* is set to a negative value in correspondence with rotation angular velocity ω of a motor. The microcomputer determines whether an anomaly has occurred in an EPS. If it is determined that an anomaly is in a power supply system (step 202: YES), the microcomputer determines whether the anomaly in the power supply system is failure of electric current flow in any phase (step 203). If it is determined that electric current flow has failed in a certain phase, the microcomputer prohibits the field weakening control and outputs a motor control signal instructing to use two other phases free from the failure of electric current flow as electric current flowing phases (two phase drive mode, step 204).
    • 微型计算机(电流指令值计算部)对电动机的旋转角速度ω进行磁场弱化控制,其中d轴电流指令值Id *被设定为负值。 微机确定EPS中是否发生异常。 如果确定电源系统中出现异常(步骤202:是),则微计算机确定电源系统中的异常是否在任何阶段都有电流流失(步骤203)。 如果在一定阶段确定电流流动失败,则微机禁止弱磁控制,并输出指示使用没有电流流动故障的其他两相的电动机控制信号作为电流流动相(两相 驱动模式,步骤204)。
