PROBLEM TO BE SOLVED: To provide an electrically-driven power steering control device which estimates steering torque with high accuracy even when a steering angle and a motor rotation angle change, namely a kinetic case.SOLUTION: An electrically-driven power steering control device 1 comprises: a torque estimation part 10 for estimating torque applied to a handle; and a motor control part 13 for controlling a motor 3 on the basis of a torque estimation value Tsub calculated by the torque estimation part. The torque estimation part 10 estimates the torque applied to the handle on the basis of a steering angle &thetas;of the handle, steering angle speed &thetas;'of the handle, motor rotation angle &thetas;, and a value obtained by feedback of the torque estimation value Tsub. |
