OPERABILITY EVALUATION DEVICE, OPERABILITY EVALUATION METHOD, AND OPERABILITY EVALUATION SYSTEM

To provide an operability evaluation device and the others which can evaluate operability of an automatic braking device.SOLUTION: A calculator of an operability evaluation device 1 comprises: a reading unit 51; and a quality evaluation unit 53. The reading unit 51 reads test data from a memory device 15 which memorizes the test data concerning a possibility that a non-operation that an automatic braking device 10 does not operate due to a positional relation between an object and a target vehicle T in which the device has to operate may occur and a possibility that an unnecessary operation that the automatic braking device 10 does not operate due to a positional relation between the object and the target vehicle T in which the device does not have to operate may occur, in a case that as a parameter the object is arranged on a lane on which the target vehicle T travels and movement speeds in a lane width direction of the object or numerical value concerning a relative position between the object and the target vehicle T is changed; and a quality evaluation unit 53 that evaluates operability of the automatic braking device 10 by evaluating balance between the possibility that the non-operation may occur and the possibility that the unnecessary operation may occur, on the basis of the test data read by the reading unit 51.SELECTED DRAWING: Figure 2 【課題】自動ブレーキ装置の作動性能を評価することが可能な作動性評価装置等を提供する。【解決手段】作動性評価装置１の計算機が、パラメータとして、対象車両Ｔが走行する車線に対象物を配置し、対象物の車線幅方向の移動速度、または、対象物と対象車両Ｔとの相対位置に関する数値を変化させた場合における、自動ブレーキ装置１０が作動する必要がある対象物と対象車両Ｔとの位置関係で作動しない不作動が発生する可能性、および、自動ブレーキ装置１０が作動不要となる対象物と対象車両Ｔとの位置関係で作動してしまう不要作動が発生する可能性に関する試験データを記憶する記憶装置１５から、試験データを読み取る読み取り部５１と、読み取り部５１が読み取った試験データに基づいて不作動が発生する可能性と、不要作動が発生する可能性とのバランスを評価することで自動ブレーキ装置１０の作動性能を評価する品質評価部５３と、を備えている。【選択図】図２
