The present invention addresses the problem of providing a steer-by-wire steering reaction force device capable of easily setting a target steering reaction force by minimizing the influence of vehicle characteristics. In order to solve the problem, the present invention provides a steer-by-wire steering reaction force device (1) comprising: an axial force estimation unit (15) that estimates the axial force of a steering actuator on the basis of the current value of the steering actuator that rotates a rotating wheel; and a standard steering force setting means (16) for setting a standard steering force on the basis of the axial force estimated by the axial force estimation means (15). A steer-by-wire steering reaction force device (1) controls a current to be supplied to a steering reaction force actuator that applies a reaction force torque to an operating element such that the steering torque of the steering-by-wire operating element becomes the standard steering force set by a standard steering force setting means (16).

    本发明的问题在于,提供一种线控转向的操舵反作用力装置,可以将车辆特性的影响最小化,而容易设定目标操舵反作用力。为了解决上述问题,本发明提供一种线控转向的操舵反作用力装置(1),包括:轴向力推定单元(15),基于使转动轮转动的操舵致动器的电流值来推定操舵致动器的轴向力;及,规范操舵力设定单元(16),基于轴向力推定单元(15)所推定的轴向力来设定规范操舵力。该线控转向的操舵反作用力装置(1)控制供给至操舵反作用力致动器的电流,所述操舵反作用力致动器以使线控转向的操作件的操舵扭矩成为规范操舵力设定单元(16)中所设定的规范操舵力的方式,对操作件赋予反作用力扭矩。
