Abstract
In an electrical power steering apparatus, steering shaft reaction torque is estimated by a steering shaft reaction torque estimation unit, and a reference road reaction torque is estimated by a reference road reaction torque estimation unit. The estimated steering shaft reaction torque and the reference road reaction torque are weighted, and, in response, a target steering reaction torque is set by a target steering reaction torque generation unit, hysteresis width and slope of the target steering reaction torque are respectively adjusted, and steering feeling is thereby easily improved.
