PROBLEM TO BE SOLVED: To easily detect failure of a sensor from the relation of detection values of a plurality of sensors mounted on a vehicle.SOLUTION: A failure determination device 100 comprises: a detection value acquisition part 11 for acquiring a detection value from a steering torque sensor 1 for detecting input torque of a driver in steering of a vehicle V, and acquiring a detection value from a steering touch sensor 2 for detecting contact of the driver with the steering; a consistency determination part 12 for determining whether or not the detection value of the steering touch sensor 2 with respect to the detection value of the steering torque sensor 1 is included in a preset inconsistency range; and a failure determination part 13 for determining that either one of the steering torque sensor 1 and the steering touch sensor 2 fails on the basis of preset reliability comparison data of the steering torque sensor 1 and the steering touch sensor 2 when the consistency determination part 12 has determined that the detection value of the steering touch sensor 2 with respect to the detection value of the steering torque sensor 1 is included in the inconsistency range.SELECTED DRAWING: Figure 1

    【課題】車両に搭載された複数のセンサの検出値の関係からセンサの故障を簡易に検出すること。【解決手段】故障判定装置100は、車両Vのステアリングにおける運転者の入力トルクを検出する操舵トルクセンサ1から検出値を取得するとともに、ステアリングに対する運転者の接触を検出する操舵タッチセンサ2から検出値を取得する検出値取得部11と、操舵トルクセンサ1の検出値に対する操舵タッチセンサ2の検出値が予め設定された不整合範囲に含まれるか否かを判定する整合性判定部12と、整合性判定部12により操舵トルクセンサ1の検出値に対する操舵タッチセンサ2の検出値が不整合範囲に含まれると判定された場合に、予め設定された操舵トルクセンサ1と操舵タッチセンサ2との信頼性対比データに基づいて、操舵トルクセンサ1と操舵タッチセンサ2のうちいずれかを故障中であると判定する故障判定部13とを備える。【選択図】図1
