Abstract
A steering apparatus for a vehicle includes a steering angle measuring unit, a vehicle speed measuring unit, a yaw rate measuring unit, a yaw rate-based reaction force control unit for controlling a steering reaction force depending on an actual yaw rate measured by the yaw rate measuring unit, and a yaw rate deviation-based reaction force control unit for determining a standard yaw rate depending on at least the steering angle and the vehicle speed, calculating a yaw rate deviation between the standard yaw rate and the actual yaw rate, and controlling the steering reaction force depending on the yaw rate deviation, and a primary control unit for executing a control operation such that a degree of contribution of the yaw rate-based reaction force control unit is decreased and a degree of contribution of the yaw rate deviation-based reaction force control unit is increased as the yaw rate deviation increases.
