Abstract:
1. A steering apparatus for a vehicle, comprising: a steering angle sensor; a vehicle speed sensor; a yaw rate sensor; a yaw rate-based reaction force control unit configured to control a steering reaction force depending on the actual yaw rate measured by the yaw rate measuring unit; a yaw rate deviation-based reaction force control unit configured to determine a standard yaw rate depending on at least the steering angle and the vehicle speed, calculate a yaw rate deviation between the standard yaw rate and the actual yaw rate, and control the steering reaction force depending on the yaw rate deviation; a primary control unit configured to execute 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; and a mechanism which applies the steering reaction force to the steering apparatus.
