PROBLEM TO BE SOLVED: To improve the accuracy of identifying an action intended by a driver responsively to the travel environment surrounding the vehicle itself.SOLUTION: An identification method includes: detecting a travel environment surrounding a vehicle itself (S101), and estimating an action possibly intended by a driver responsively to the travel environment (S102); and detecting action timing in the driver intending to act (S103), and identifying an action matching the action timing from actions possibly intended by the driver as an action intended by the driver (S104).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】自車両の周囲の走行環境に対して運転者が意図する行動をより正確に特定する。【解決手段】自車両の周囲の走行環境を検出し(S101)、走行環境に対して運転者が意図し得る行動を推定する(S102)。また、運転者が行動しようとするときの行動タイミングを検出し(S103)、運転者が意図し得る行動から行動タイミングに一致する行動を、運転者の意図した行動として特定する(S104)。【選択図】図2
