Steering auxiliary motor control device in eps system, and method thereof

Abstract

Disclosed are a steering auxiliary motor control device and a method thereof, the device comprising: a receiving unit for receiving steering angle information and driver steering torque information from a sensor included in a vehicle; a maximum steering angle determination unit for determining the maximum steering angle of the vehicle on the basis of the steering angle information and preset reference steering angle information; and a limited motor torque determination unit for determining limited motor torque for limiting maximum motor torque outputted from a steering auxiliary motor on the basis of a first condition including the steering angle information, the maximum steering angle information, and steering angle holding time information and/or a second condition including the driver steering torque information, over-torque limit entry torque information, over-torque limit release torque information, and steering torque holding time information.
