Abstract

A steer-by-wire steering system including: an operation member (10) to be operated by a driver; a reaction force applying device (12) configured to apply an operation reaction force to the operation member (10); a steering device(16) including a steering motor (38) that is an electric motor as a drive source and configured to steer a wheel (14); and a controller (40, 42) configured to control the reaction force applying device (12) and the steering device (16), wherein the controller (40, 42) determines the operation reaction force including a steering-current-dependent component which is a component based on a current supplied to the steering motor (38) and a steering-speed-dependent correction component to reduce the steering-current-dependent component based on a steering speed; and wherein the controller (40, 42) determines the steering-speed-dependent correction component such that when the steering speed exceeds a set speed, the steering-speed-dependent correction component is not larger than a value at the set speed.
