Description
具体的には、車載システムは、ACC(Adaptive Cruise Control)を行うシステムである。
なお、各図において、同一符号は同一部分を示す。
本発明の実施例による車載システム100を図1に示す。車載システム100は、GNSSアンテナ101、V2Xアンテナ102、カメラ103、GNSS受信機104、V2X送受信機105、画像処理回路106、CPU107(Central Processing Unit)、ブレーキ制御108等を備える。なお、ブレーキ制御108は、所定のプログラムであり、メモリ等の記憶装置109に記憶される。
具体的には、例えば、CPU107(判定部)は、GNSS受信機104(第1受信機)によって計算された自車両201の位置が、V2X受信機(第2受信機)によって受信された交差点位置情報が示す交差点の位置から所定の距離以内となったときに、自車両201が交差点エリアに侵入したと判定する。これにより、路側器から受信した交差点位置情報を用いて、自車両201が交差点エリアに侵入したか否かを判定することができる。
なお、区画線の検知が途切れた状態とは、検知された区画線が不連続であるということもできる。
図9では、図8のフローチャートと比較してS23の処理が追加されている。CPU107は、交差点信号が青の場合(S23:YES)、自車両201を前方車両202に追従走行させるACCを解除する(S25)。一方、CPU107は、交差点信号が青でない場合(S23:NO)、S40へ処理を進める。
例えば、上述した実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。
