Description
まず、本実施形態に係る運転支援装置が搭載される車両全体の構成について、図1を参照して説明する。図1は、実施形態に係る車両の構成を示すブロック図である。
次に、回避支援制御の実行時に発生し得る技術的問題点について、図2を参照して説明する。図2は、回避対象とは異なる減速要因が存在する場合に発生し得る技術的問題点を示す平面図である。
次に、本実施形態に係る運転支援装置200の動作の流れについて、図3を参照して説明する。図3は、実施形態に係る運転支援装置の動作の流れを示すフローチャートである。
次に、本実施形態に係る運転支援装置200によって得られる技術的効果について説明する。
上述した実施形態は、減速要因が存在する場合に車両10の運転者が減速操作を実行することを想定したものである。しかしながら、車両10の運転者による減速操作に代えて又は加えて、運転支援装置200以外の別システムによって実行され得る減速制御を考慮するようにしてもよい。例えば、車両10が減速要因の存在を検出して自動的に減速制御を実行するシステムを備えている場合、減速操作予測部230は、この別システムによる減速制御が実行されるか否かを予測するようにしてもよい。そして、別システムによる減速制御が実行されると予測された場合に、制御条件変更部240が回避支援制御の支援量又は開始タイミングの少なくとも一方を変更するように構成すればよい。
以上説明した実施形態から導き出される発明の各種態様を以下に説明する。
付記1に記載の運転支援装置は、車両の前方に回避すべき対象物が存在する場合に、前記車両と対象物との衝突を回避するための回避支援制御を実行する支援手段と、前記車両の前方に前記対象物が存在する場合に、前記対象物とは異なる前記車両の周辺に存在する減速要因に基づいて、前記車両の減速操作が行われることを予測する予測手段と、前記減速操作が行われることが予測された場合に、前記減速操作が行われることが予測されない場合と比較して、前記回避支援制御に係る支援量を小さくする処理、及び前記回避支援制御の開始タイミングを遅くする処理の少なくとも一方を実行する変更手段とを備える。
付記2に記載の運転支援装置では、前記予測手段は、前記減速要因に基づいて、前記車両の運転者によって減速操作が行われることを予測する。
