PROBLEM TO BE SOLVED: To provide a steering simulator with which it is possible to easily calculate steering torque in steering simulation.SOLUTION: Provided is a steering simulator 1 for calculating steering torque for adjusting the steering angle of a prescribed vehicle model M to an intended steering angle on the basis of a pre-acquired intended steering angle, comprising: a feed-forward unit 10 for calculating predicted steering torque from the intended steering angle utilizing steering characteristic map data D that includes predicted steering torque previously correlated for each value of intended steering angle; a vehicle model arithmetic unit 11 for inputting the pre-acquired previous steering torque to the vehicle model M and thereby calculating the previous steering angle of the vehicle model M; a feedback unit 12 for calculating corrected steering torque on the basis of a difference between the intended steering angle and the previous steering angle; and a steering torque calculation unit 13 for calculating steering torque on the basis of the predicted steering torque and the corrected steering torque.SELECTED DRAWING: Figure 2

    【課題】操舵シミュレーションにおける操舵トルクの算出を容易に行うことができる操舵シミュレーション装置を提供する。【解決手段】予め取得された目標操舵角に基づいて、所定の車両モデルMの操舵角を目標操舵角に合わせるための操舵トルクを算出する操舵シミュレーション装置1であって、目標操舵角の値ごとに予め対応付けられた予測操舵トルクを含む操舵特性マップデータDを利用して、目標操舵角から予測操舵トルクを算出するフィードフォワード部10と、予め取得された前回操舵トルクを車両モデルMに入力することで、車両モデルMの前回操舵角を算出する車両モデル演算部11と、目標操舵角と前回操舵角との差に基づいて、修正操舵トルクを算出するフィードバック部12と、予測操舵トルクと修正操舵トルクとに基づいて、操舵トルクを算出する操舵トルク算出部13と、を備える。【選択図】図2
