Control method for electric power steering apparatus for vehicle

摘要

A control method for an electric power steering apparatus for a vehicle includes a control unit having a target value generator and a primary delay system setting unit. The target value generator generates a target value of a steering force or a motor output. The primary delay system setting unit sets a primary delay system, in which a damper value, which changes in accordance with a vehicle speed, is set negative in a low-speed range where the vehicle speed is V0 to V1 (V0<V1) and changed in accordance with the vehicle speed. The damper value is calculated with a steering angular speed of an electric power steering unit. The calculated value is fed back to a difference between the target value and an actual value. The electric power steering unit is controlled using a value obtained by filtering the difference through the primary delay system.
