To provide a sensor reliability calculation device and a method for calculating the reliability of a sensor which can suppress reduction of reliability of the result of sensor fusion caused by an environmental condition.SOLUTION: A sensor reliability calculation device 200 for calculating the reliability of sensors 201 to 203 has an operation device 200a in which detection data of a plurality of sensors 201 to 203 is input. The operation device 200a calculates a relative reliability showing the degree of degradation of the performance according to an environmental condition on the basis of detection data of a second sensor of the sensors 201 to 203 having a different sensing modality from that of a first sensor of the sensors 201 to 203 as a target sensor.SELECTED DRAWING: Figure 2 【課題】環境条件に起因するセンサフュージョン結果の信頼性低下を抑制することが可能なセンサ信頼性算出装置およびセンサ信頼性算出方法を提供する。【解決手段】センサ２０１～２０３の信頼性を算出するセンサ信頼性算出装置２００において、複数のセンサ２０１～２０３の検出データが入力される演算装置２００ａを備え、演算装置２００ａは、複数のセンサ２０１～２０３のそれぞれを対象として、対象とするセンサとは異なるセンシングモダリティを有する別のセンサの検出データを基に、環境条件に応じた性能低下度合いを示す相対信頼度を算出する。【選択図】 図２
