Abstract
Description
本発明の実施の形態の自動運転システムは、自動運転車両に搭載される自動運転のための制御システムであって、例えばSAE(Society of Automotive Engineers)のレベル定義においてレベル3以上の自動運転レベルを実現することができる制御システムである。本実施の形態の自動運転システムが搭載される自動運転車両は、例えば図1にブロック図で示される構成の制御系を有する。
図1には、ECU1が自動運転システム10として動作する場合の機能がブロックで詳細に表現されている。以下、自動運転システム10が有する機能について説明する。
本実施の形態の自動運転システム10による走行計画の立て直し方法の具体例について、比較例の自動運転システムとの車両の挙動の比較を交えて説明する。まず、比較例の自動運転システムによる車両の挙動の一例について図5を用いて説明する。図5は、比較例の自動運転システムにおける車両の挙動に関係するパラメータの時間による変化を示すタイムチャートである。パラメータとして、上段から順に、ドライバのブレーキ操作或いは安全システムの作動による制動力、計画速度及び実速度、自動運転システムの速度制御(ADS速度制御)による駆動力、車両の前後加速度、そして、参照曲率及び参照曲率真値が示されている。
最後に、ABSが作動した場合の走行計画の立て直し方法の一例について説明する。ABSが作動した場合の走行計画の立て直し方法には、その他の安全システム40が作動した場合の走行計画の立て直し方法との間で違いが有る。ここでは、その他の安全システム40の例としてTRCを挙げ、TRCが作動した場合の走行計画の立て直し方法と比較する。
