Claim:
1. A steering control device comprising: a steering reaction force actuator configured to impart a steering reaction force to a steering unit; a steering reaction force control amount calculation unit that computes a steering reaction force control amount in which a steering reaction force increases in a direction in which a lateral position of a host vehicle moves away from a travel path partition line in commensurate proximity to the travel path partition line; a steering reaction force control unit that controls the steering reaction force actuator based on the steering reaction force control amount; a turning actuator for imparting turning torque to a turning part mechanically separated from the steering unit; a turning control amount calculation unit that computes a turning control amount in which a turning amount increases in the direction in which the lateral position of the host vehicle moves away from the travel path partition line in commensurate proximity to the travel path partition line; a turning control unit that controls the turning actuator based on the turning control amount; a reaction force suppression processing unit that computes a steering reaction force control amount of reaction force suppression processing for reducing the steering reaction force control amount when a state in which the steering reaction force control amount has been at a predetermined threshold value or higher for a predetermined length of time, and that conducts a reaction force suppression processing to control the steering reaction force actuator based on the steering reaction force control amount of reaction force suppression processing in lieu of the steering reaction force control amount; and a turning amount holding unit that holds the turning control amount at a value occurring at a starting time point of the reaction force suppression processing when the reaction force suppression processing has started.
