Abstract
A steering reaction force control device, a steering reaction force control method, and a steering reaction force control system according to the present invention determine an amount of torque of a steering reaction force imparted by the reaction force actuator and a direction of torque for returning the steering operation input member to a neutral position from a physical quantity related to a vehicle speed of the vehicle and a physical quantity related to the operation information of the steering operation input member, and output a control signal based on the amount of torque and the direction of torque to the reaction force actuator. As a result, it is possible to prevent the hunting of the operating position of the steering operation input member when the steering operation input member is retained in a given steering position.
