PROBLEM TO BE SOLVED: To provide a driving skill determination device capable of highly accurately determining vehicle driving skill even when traveling at a relatively low speed or when traveling along a curved road with a small curvature.SOLUTION: A driving skill determination device 11 comprises: an acquisition part 31 for acquiring time series signals related to an operation associated with at least one of operation members including an accelerator pedal 14, a brake pedal 16 and a steering wheel 18; an analysis part 33 for performing frequency analysis on the time series signals related to the operation acquired by the acquisition part 31; and a determination part 37 for performing a driving skill determination for a vehicle 12, on the basis of an analysis result on the time series signals related to the operation. A low pass filter 23 is applied to, and then a phase compensation is performed to the time series signals related to the operation acquired by the acquisition part 31. The analysis part 33 extracts a differential signal between the time series signals related to the operation acquired by the acquisition part 31 and a time series signals related to the operation after the phase compensation, and then performs the frequency analysis to the extracted differential signal.SELECTED DRAWING: Figure 1A

    【課題】比較的低速での走行時や曲率の緩やかな曲線路を走行時であっても、車両の運転技量判定を高い精度で遂行可能な運転技量判定装置を提供する。【解決手段】運転技量判定装置11は、アクセルペダル14、ブレーキペダル16、及びハンドル18のうち少なくとも1つの操作部材に係る操作に関連する操作関連時系列信号を取得する取得部31と、取得部31で取得した操作関連時系列信号に対して周波数解析を行う解析部33と、操作関連時系列信号に対する解析結果に基づいて、車両12の運転技量判定を行う判定部37と、を備える。取得部31で取得した操作関連時系列信号に対し、ローパスフィルタ23を作用させた後、位相補償を行う。解析部33は、取得部31で取得した操作関連時系列信号と、位相補償後の操作関連時系列信号との差分信号を抽出し、抽出された差分信号に対して周波数解析を行う。【選択図】図1A
