PROBLEM TO BE SOLVED: To provide an operation request determination method and a device therefor, by which, prior to motion of an operator, an operation request of the operator can be determined via desynchronization relating to an event of a specific brain wave component.SOLUTION: A vehicle control device 2 that determines an operation request of an occupant with respect to a vehicle 1 on the basis of the brain wave of the occupant who is driving, comprises: an electroencephalograph 21 that time-serially detects changes in brain wave components W1, W2 in a specific frequency band of the brain wave； a phenomenon determination part 22 that determines whether ERD is detected, in which the changes in the specific brain wave components W1, W2 detected by the electroencephalograph 21 have a tendency toward decrease； and a characteristic termination part 23 that determines that a vehicle operation is requested by the occupant when initial change rates ΔW1, ΔW2 of the ERD, determined by the phenomenon determination part 22, are equal to or higher than predetermined thresholds A1, A2 or amplitude values W1a, W2a of the ERD are equal to or greater than the predetermined determination values B1, B2.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】特定脳波成分の事象関連脱同期を介して操作者の操作要求を操作者の動作に先行して判定することができる操作要求判定方法及びその装置を提供する。【解決手段】運転中の乗員の脳波に基づいて車両１に対する乗員の操作要求を判定する車両用制御装置２であって、脳波のうち特定周波数帯域の脳波成分Ｗ１，Ｗ２の変化を時系列的に検出する脳波計２１と、脳波計２１により検出された特定脳波成分Ｗ１，Ｗ２の変化が減少傾向になるＥＲＤであるか判定する現象判定部２２と、現象判定部２２で判定されたＥＲＤの初期変化率ΔＷ１，ΔＷ２が所定閾値Ａ１，Ａ２以上又はＥＲＤの振幅値Ｗ１ａ，Ｗ２ａが所定判定値Ｂ１，Ｂ２以上のとき、乗員による車両の操作要求があると判定する特性判定部２３と、を有する。【選択図】 図２
