Abstract
A control apparatus of a steering system for vehicles that controls a turning mechanism by using steering information communicated electrically, includes a turning angle control section that calculates a motor current command value to make a turning angle detected in the turning mechanism follow a target turning angle, and has a friction compensating section that calculates a compensation motor current command value for compensating a follow-up delay of the turning angle caused by a friction in the turning mechanism by performing filter processing to velocity information. The turning angle control section performs compensation by the compensation motor current command value in calculation of the motor current command value, and the control apparatus controls the turning mechanism based on the motor current command value.
