Description
図1に示すように、自車位置推定装置100は、装置を統括的に制御する自車位置推定ECU [Electronic Control Unit]10を備えている。自車位置推定ECU10は、CPU[Central Processing Unit]、ROM[Read Only Memory]、RAM[Random Access Memory]、CAN[Controller Area Network]通信回路等を有する電子制御ユニットである。自車位置推定ECU10では、例えば、ROMに記憶されているプログラムをRAMにロードし、RAMにロードされたプログラムをCPUで実行することにより各種の機能を実現する。自車位置推定ECU10は、複数の電子制御ユニットから構成されていてもよい。
次に、本実施形態における自車位置推定装置100の縦位置推定処理について図4を参照して説明する。図4は、自車位置推定装置の縦位置推定処理の一例を示すフローチャートである。縦位置推定処理は、例えば車両の走行中に実行される。
Claims (1)
- 自動運転を行う車両の前記自動運転の進路に応じた道路である走行道路の延在方向における前記車両の地図上の位置である縦位置と前記走行道路の幅方向における前記車両の地図上の位置である横位置とを含む自車位置を推定する自車位置推定装置であって、
前記走行道路を走行する前記車両の車速及び前記車両のピッチ角を認識する走行状態認識部と、
前記車両に搭載された位置測定器の測定結果と前記車両の車速とに基づいて、前記車両の地図上の測定位置を認識する車両位置認識部と、
前記走行道路の高さ情報又は勾配情報を含む地図情報を記憶する地図データベースと、
前記車両の地図上の測定位置と前記地図情報とに基づいて前記走行道路上で地図上の最大高さと最低高さの差が所定の閾値以上となる一定距離の区間を高さ変化特徴区間として設定すると共に、前記車両の地図上の測定位置に基づいて前記車両が前記高さ変化特徴区間の付近に位置するか否かを判定する推定判定部と、
前記推定判定部により前記車両が前記高さ変化特徴区間の付近に位置すると判定された場合に、前記車両の測定位置、前記地図情報、及び前記車両のピッチ角に基づいて、前記走行道路に沿った車両のピッチ角変化レートと前記走行道路に沿った地図上の高さ変化レートとの比較結果から、前記縦位置を推定し、前記推定判定部により前記車両が前記高さ変化特徴区間の付近に位置すると判定されなかった場合には前記縦位置の推定を行わない縦位置推定部と、
を備える、自車位置推定装置。
