Apparatus and method for controlling steering system of vehicle

A method for determining an assist torque of a power steering system in a vehicle: setting an initial slope indicating a correlation between a driver steering torque and a vehicle lateral acceleration, wherein the initial slope is a tangential slope at a lowest point of the vehicle lateral acceleration defined in a diagram; setting a maximum driver steering torque, which is a maximum value of a steering torque that a driver applies through a steering wheel of the vehicle; calculating an assist torque based on the driver steering torque in response to performance of a steering assist, from the set initial slope and maximum driver steering torque, and vehicle eigen value information based on a predetermined equation; generating a torque map in which an assist torque value is set based on the driver assist torque upon the performance of the steering assist using assist torque values obtained for each driver steering torque detected by a torque sensor; and determining, by an electronic control unit (ECU), the assist torque value corresponding to the driver steering torque using the generated torque map.
