Abstract
A manual steering command value calculation unit is configured to use road information including information on a road reaction torque to calculate a manual steering command value when a first condition that at least one of input torques for which a dead zone processing unit is provided is outside a dead zone range is satisfied, and not to use the road information to calculate the manual steering command value when the first condition is not satisfied. When alert vibration torque is being applied, the manual steering command value calculation unit uses the road information to calculate the manual steering command value for a predetermined period from a time when a state in which the first condition is satisfied changes to a state in which the first condition is not satisfied.
