Abstract:
1. A steering system for an automotive vehicle, comprising: a steering mechanism configured to steer steerable wheels of the vehicle; an operation inputting section that is mechanically separated from the steering mechanism; a reaction force actuator configured to provide a steering reaction force for the operation inputting section on the basis of a reaction force command value based on conditions of a road surface on which the vehicle runs; a steering actuator configured to drive the steering mechanism on the basis of a turning angle command value which accords with a steering angle of the operation inputting section; a turning angle correction value setting section that sets a turning angle correction value on the basis of the reaction force command value; and a turning angle command value correcting section that subtracts the turning angle correction value from the turning angle command value, wherein the turning angle correction value setting section is configured to set the turning angle correction value in such a manner that, as the reaction force command value becomes larger, the turning angle correction value becomes larger.
