Controlling steering sensitivity for alternative steering options

A steering control device that controls a steering device of a vehicle, wherein:

• the steering device has a structure in which a power transmission path between an operation unit having an operating lever and a steering unit configured to steer a steered wheel is separated;
• the steering control device includes
• a target steering corresponding value computing unit configured to compute a target steering corresponding value that is a target value of a convertible value that can be converted into a steered angle of the steered wheel, and
• a control signal generating unit configured to generate a control signal for actuation of the steering unit, based on the target steering corresponding value;
• the target steering corresponding value computing unit is configured to execute
• low sensitivity determination processing for determining whether or not a low sensitivity condition for reducing an amount of change in the steered angle with respect to an amount of change in an amount of operation of the operating lever is satisfied,
• normal computation processing for computing the target steering corresponding value based on the amount of operation when the low sensitivity condition is not satisfied, and
• low sensitivity computation processing for computing, based on the amount of operation, the target steering corresponding value having a smaller absolute value than the target steering corresponding value computed by the normal computation processing, when the low sensitivity condition is satisfied;
• and
• the target steering corresponding value computing unit is configured to
• further execute prohibition determination processing for determining whether or not a prohibition condition for prohibiting reduction in the amount of change in the steered angle with respect to the amount of change in the amount of operation is satisfied, and
• execute the normal computation processing without executing the low sensitivity computation processing when the prohibition condition is satisfied, even when the low sensitivity condition is satisfied.
