Claim 0:
1. A steering control device configured to control a reaction motor that generates a steering reaction force applied to a steering wheel of a steer-by-wire steering system in which power transmission between the steering wheel and turning wheels is cut off, the steering control device comprising:
a first processor configured to change a virtual operation range of the steering wheel according to a steering state or a vehicle state by controlling the reaction motor; and
a second processor configured to change a degree of change of the virtual operation range of the steering wheel when an operation position of the steering wheel reaches a position at or within a predetermined threshold of a limit position of the virtual operation range, wherein
the first processor is configured to calculate a limit value of the virtual operation range of the steering wheel according to a value of a vehicle speed,
the second processor is configured to fix the value of the vehicle speed which is used to calculate the limit value when the operation position of the steering wheel reaches the position at or within the predetermined threshold of the limit position of the virtual operation range, and
the second processor is configured to non-instantaneously change the value of the vehicle speed which is used to calculate the limit value of the virtual operation range of the steering wheel to a current value of the vehicle speed which is detected by a vehicle speed sensor when the operation position of the steering wheel becomes no longer within the predetermined threshold of the limit position of the virtual operation range.
