Abstract
A system and method for controlling a steering reaction force in which at least one of motion state variables of a vehicle is estimated when a steering wheel of the vehicle is operated on the basis of a vehicle model which represents a mathematical model of the vehicle having a desired performance of motion, a target value of the steering reaction force imposed on a steering wheel is determined on the basis of the estimated value of the motion state variable, and the steering reaction force imposed on the steering wheel is generated so as to become substantially equal to the target value. The steering reaction force control system achieves the generation of the steering reaction force on the steering wheel on the basis of a vehicle turning motion information as motion state variables such as a lateral acceleration of the vehicle and/or yaw rate of the vehicle.
