摘要：Provided is a steer-by-wire steering system that is less likely to make a driver feel a sense of discomfort. The steer-by-wire steering system is structured such that a steering input device (1) that is steered by a driver is mechanically coupleable to a
steering operation device (2) that causes steered wheels (16) to be steered in accordance
with the steering of the steering input device (1) by a driver. The steer-by-wire steering system includes a steering-side motor (22) that supplies a steering shaft (11) of the steering input device (1) with a steering reaction force, a steered-side motor (32) that supplies a rack shaft (14) of the steering operation device (2) with a steering force, and a power supply control circuit (40) that controls a power supply to the steering-side motor (22) so that the steering-side motor (22) generates the steering reaction force and that controls a power supply to the steered-side motor (32) so that the steered-side motor (32) generates the steering force. When the duty ratio of a duty signal that is generated to control the power supply to the steered-side motor (32) reaches a setting value that is defined to indicate that a steered angle becomes unable to follow a steering angle, the power supply control circuit (40) controls the power supply to the steering-side motor (22) such that the steering-side motor (22) increases the steering reaction force.
