STEERING REACTION CONTROL DEVICE, STEERING REACTION CONTROL METHOD, AND STEERING REACTION CONTROL SYSTEM

A steering reaction force control device, a steering reaction force control method, and a steering reaction force control system according to a physical quantity related to a vehicle speed of a vehicle and a physical quantity related to operation information of a steering operation input member. A torque amount of a steering reaction force applied by a reaction force actuator and a torque direction for returning the steering operation input member to a neutral position are obtained, and a control signal based on the torque amount and the torque direction is output to the reaction force actuator. As a result, oscillation of the operation position of the steering operation input member can be suppressed in a steering holding state of the steering operation input member. 本发明所涉及的转向操纵反作用力控制装置、转向操纵反作用力控制方法以及转向操纵反作用力控制系统根据与车辆的车速相关的物理量、和与转向操纵操作输入构件的操作信息相关的物理量，求出反作用力致动器所赋予的转向操纵反作用力的扭矩量、和用于使所述转向操纵操作输入构件返回到中立位置的扭矩方向，向反作用力致动器输出基于所述扭矩量和所述扭矩方向的控制信号。由此，在转向操纵操作输入构件的转向保持状态下，能够抑制转向操纵操作输入构件的操作位置振荡。
