摘要： A highly safe electric power steering device including a control device for determining the failure of a motor current detector based on the difference between the motor current estimate value and the detected motor current value is provided. The abnormality determining unit computes the absolute value of difference between the motor current estimate value and the detected motor current value, measures the number of times when the absolute value of difference exceeded the predetermined threshold value within the predetermined period, and measures further the cumulative value of the number of times of exceeding the threshold value within the predetermined period. When the cumulative value exceeded the predetermined reference number of times for determining abnormality, the motor current detector is determined to be abnormal.
