To appropriately detect failures of a steering system of a vehicle.SOLUTION: A control device 10 includes: a model construction part 103 for constructing a vehicle model for estimating steering force to vehicle speed and a steering angle; an estimation part 104 for acquiring measured values of the vehicle speed and the steering angle, inputting the measured values of the vehicle speed and the steering angle to the vehicle model, and deriving the estimated value of the steering force; and a determination part 105 for acquiring the measured value of the steering force, comparing the measured value of the steering force with the estimated value of the steering force, and determining that the steering system of a vehicle fails when a deviation between the values is larger than a predetermined threshold.SELECTED DRAWING: Figure 1

    【課題】車両のステアリング系の故障を適切に検知すること。【解決手段】制御装置10は、車速及び操舵角に対する操舵力を推定する車両モデルを構築するモデル構築部103と、車速及び操舵角の実測値を取得すると共に、該車速及び操舵角の実測値を車両モデルに入力し、操舵力の推定値を導出する推定部104と、操舵力の実測値を取得すると共に、該操舵力の実測値と操舵力の推定値とを比較し、これらの値同士の乖離が所定の閾値よりも大きい場合に、車両のステアリング系が故障していると判定する判定部105と、を備える。【選択図】図1
