Title:
電動パワーステアリング装置及びその制御方法
Document Type and Number:
Japanese Patent JP4458926
Kind Code:
B2
Abstract:
In an electric power steering apparatus in which a third motor target current is determined from a first motor target current determined on the basis of a detection torque from a steering torque detection means and a second motor target current determined using at least a detection value of the motor current detection circuit as one of inputs, and a motor drive signal is calculated on the basis of the third motor target current and a detection current from the motor current detection circuit to control a motor current, there is included a motor current detection circuit failure judgment means for judging a failure of the motor current detection circuit, and when a judgment of failure is made, at least the second motor target current is limited.
