To provide an operation support method for enabling appropriate control for a vehicle to travel even in a case where the state changes from being unable to recognize a signal indication at an intersection to being able to recognize it when the vehicle travels toward the intersection, thus requiring the travel control to be changed.SOLUTION: An operation support method is used for setting a first vehicular speed profile P1 for decelerating a vehicle itself at a stop position De at given first deceleration and controlling the vehicle itself to travel on the basis of the first vehicular speed profile P1 in the case of recognizing that a signal indication is a stop signal or an intermediate signal before timing for starting deceleration as per the first vehicular speed profile P1. Further, in the case of determining that a signal indication cannot be recognized, the method includes: setting a target vehicular speed profile P4 at or later than deceleration start timing as per the first vehicular speed profile P1 (D3), the profile that allows a vehicular speed to be higher than the first vehicular speed profile P1; and controlling the vehicle itself on the basis of the target vehicular speed profile P4.SELECTED DRAWING: Figure 9
【課題】車両が交差点に向かって走行している時に、交差点の信号表示を認識できない状態から信号表示を認識できるようになり、走行制御を変更することになったとしても、車両の走行を適切に制御することができる運転支援方法を提供する。【解決手段】運転支援方法は、所定の第1減速度で自車両を交差点の停止位置Deに減速させる第1車速プロファイルP1を設定し、第1車速プロファイルP1における減速開始タイミングまでに、信号表示が停止信号または中間信号であると認識した場合に、第1車速プロファイルP1に基づいて自車両の走行を制御する運転支援方法であって、信号表示が不認識であると判定している場合、第1車速プロファイルP1における減速開始タイミング以降においてD3、第1車速プロファイルP1より車速が高い目標車速プロファイルP4を設定し、目標車速プロファイルP4に基づき、自車両を制御する。【選択図】図9
