PROBLEM TO BE SOLVED: To provide a steering reaction force control device for a steer-by-wire having stable steering reaction force for achieving comfort steering feeling on the basis of a behavior state of a vehicle and a road surface state without being affected by high frequency components included in an acquisition value of a sensor or the like to be used for generating the steering reaction force.SOLUTION: In a steering reaction force control device for a steer-by-wire, steering control means 16 includes: turning reaction force or the like estimation means 17 for calculating an estimation value of turning reaction force or the like from a vehicle motion model 20; and comparison means 18 for comparing the estimation value calculated in the turning reaction force or the like estimation means 17 with a detection value detected from a turning reaction force sensor 8 and selecting either the estimation value or the detection value; and steering reaction force generation means 19 which uses the selected estimation value or detection value for generation of steering reaction force. The comparison means 18 selects the estimation value calculated from the vehicle motion model 20 if vehicle speed is a fixed value or more, and selects the detection value detected from the turning reaction force sensor 8 if the vehicle speed is less than the fixed value.SELECTED DRAWING: Figure 2

    【課題】操舵反力の生成に用いられるセンサ等の取得値に含まれる高周波成分の影響を受けず、且つ、車両の挙動状態、路面状態に基づいた快適な操舵感を実現する安定した操舵反力のステアバイワイヤの操舵反力制御装置を提供する。【解決手段】このステアバイワイヤの操舵反力制御装置は、ステアリング制御手段16に、車両運動モデル20から転舵反力等の推定値を演算する転舵反力等推定手段17と、転舵反力等推定手段17で演算された推定値と、転舵反力センサ8から検出した検出値とを比較し、推定値および検出値のいずれか一方を選択する比較手段18とを設ける。選択された推定値または検出値を操舵反力の生成に用いる操舵反力生成手段19を設ける。比較手段18は、車両速度が定められた値以上であれば、車両運動モデル20から演算された推定値を選択し、車両速度が定められた値未満であれば、転舵反力センサ8から検出した検出値を選択する。【選択図】図2
