Abstract
A vehicle steering system is applied to a vehicle including wheels including at least turning wheels and includes a steering member, a reaction actuator, a turning device, and an electronic control unit. The electronic control unit is configured to: control the turning device based on a target turning angle corresponding to an amount of steering of the steering member; control the reaction actuator such that a steering reaction force based on a first turning axial force corresponding to the target turning angle and a second turning axial force corresponding to an output current or an output torque of the turning device is generated; and change a first proportion of the first turning axial force distributed to the steering reaction force and a second proportion of the second turning axial force distributed to the steering reaction force based on a slip rate of the wheels.
