Claim 3:
4. 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 limit a change per unit time of the limit value calculated by the first processor when the steering wheel is held at a constant steering angle with respect to a neutral position of the steering wheel, and
the second processor is configured to non-instantaneously change the limit value of the virtual operation range of the steering wheel to a current limit value which is calculated by the first processor when a state in which the steering wheel is held at the constant steering angle with respect to the neutral position of the steering wheel is released.
