    • This invention provides a motor control apparatus and vehicle steering apparatus capable of determining whether the motor control CPU is normal or abnormal with an inexpensive structure. A monitor circuit 70 of an ECU 50 outputs a trigger signal trg based on an excitation signal of a motor resolver 42 from a trigger output circuit 71; samples and holds U-phase actual current value Iu, V-phase actual current value Iv and cos phase signal outputted from the motor resolver 42 with S/H circuit 72 based on the trigger signal trg; acquires q-axis current instruction value Iq* through wiring 80; and determines whether the CPU 60 is normal or abnormal based on consistency or inconsistency of polarity signs introduced from the relation among the cos phase signal, q-axis current instruction value Iq*, U-phase actual current value Iu and V-phase actual current value Iv based on a predetermined expression with an operational circuit 73, sign determining circuits 74, 75, 76, multiplying circuit 77 and sign comparing circuit 78 and outputs "1" as determination information if it is normal and "-1" if it is abnormal.
    • 本发明提供了一种电机控制装置和车辆转向装置,其能够以廉价的结构来确定电动机控制CPU是正常还是异常。 ECU50的监视电路70从触发输出电路71输出基于电动机解算器42的励磁信号的触发信号trg; 基于触发信号trg,采用S / H电路72从电机分解器42输出的U相实际电流值Iu,V相实际电流值Iv和cos相位信号; 通过布线80获取q轴电流指令值Iq *; 并且基于从cos相位信号,q轴电流指令值Iq *,U相实际电流值Iu与V相实际电流之间的关系引入的极性符号的一致性或不一致性来判定CPU60是正常还是异常 基于具有运算电路73的预定表达式的值Iv,符号确定电路74,75,76乘法电路77和符号比较电路78,并且如果它是正常的则将“1”作为确定信息输出,如果是正则则输出“-1” 不正常。
