PROBLEM TO BE SOLVED: To provide a steering reaction force adjusting device of the moving body which can adjust steering reaction force so that it may approach the steering reaction force more suitable for a drivers fatigue condition.SOLUTION: A controller 6 for the steering reaction force is equipped with a muscular strength detecting section 11, a fatigue estimating section 12, and reaction adjusting section 13. Furthermore, the muscular strength detecting section 11 estimates muscular strengths of a plurality of muscular chosen from muscles of arm located at from a shoulder and arm of the driver using a muscle framework model and admittance measuring method. Additionally, the steering reaction force added to an operation element is adjusted based on estimated fatigue degrees of the plurality of muscle and steering condition of the operation element.COPYRIGHT: (C)2012,JPO&INPIT【課題】運転者の疲労状態により適した操舵反力に近づくように当該操舵反力を調整可能とすることを目的とする。【解決手段】操舵反力用コントローラ6は、筋力検出部11と、疲労推定部12と、反力調整部13とを備える。筋力検出部11は、筋骨格モデルとアドミタンス計測手法をもちいて、運転者の肩部から手までに位置する腕の筋肉のうちから選択した複数の筋の筋力を推定する。そして、推定した複数の筋の疲労度と操作子の操舵状態とに基づき、操作子に付加する操舵反力を調整する。【選択図】図2
