A control device for an electric power steering device is provided with an arithmetic processing device having a comparison unit, a failure diagnosis unit, and a drive control unit. The comparison unit determines a magnitude relationship by comparing a difference between a first output signal output from the first sensor and a second output signal output from the second sensor with a first threshold value, and determines a magnitude relationship by comparing a difference between the first output signal and a third output signal output from the third sensor with a second threshold value. The failure diagnosis unit specifies any abnormal sensor from among the first sensor, the second sensor, and the third sensor on the basis of the result of the comparison unit. The drive control unit generates a drive control signal for driving the electric motor using output values from two normal sensors, which are not designated as abnormal sensors, among the first sensor, the second sensor, and the third sensor.

    电动动力转向装置的控制装置具备运算处理装置,该运算处理装置具有比较部、故障诊断部、驱动控制部。比较部将从第一传感器输出的第一输出信号与从第二传感器输出的第二输出信号之差与第一阈值进行比较来判断大小关系,将第一输出信号与从第三传感器输出的第三输出信号之差与第二阈值进行比较来判断大小关系。故障诊断部基于比较部的结果,从第一传感器、第二传感器与第三传感器之中指定任意一个异常的传感器。驱动控制部使用来自第一传感器、第二传感器与第三传感器之中未被指定为异常的传感器的两个正常传感器的输出值,生成驱动电动马达的驱动控制信号。
