    • PROBLEM TO BE SOLVED: To improve the feeling of operation without the need of final tuning work in the case where a mechanism giving a strong inertia torque exists near a steering wheel in a steering system of EPS1. SOLUTION: According to the EPS1, an assist motor 2 forms the working point of the inertia torque in the steering system on the side of steered-wheels relative to the side of a torque sensor 5, and a microcomputer 23 includes a correction means 30 for correcting the sum of a basic assist current-carrying amount and an inertia compensation current-carrying amount.
