Description
さらに、請求項1の電気自動車によれば、平面視において端部側のスロープと側部側のスロープとの床下の収納位置が重なる場合と比べて車室の低床化を図ることができるため、広い車室空間を確保することができる。
(構成)
本実施形態の車両10は完全自動運転を可能とする電気自動車である。図1及び図2に示されるように、車両10の外観は、ルーフ20B、前壁部20C、側壁部20D及び後壁部20Eに囲まれた略直方体形状であって、車両前方には前輪24Aが設けられ、車両後方には後輪24Bが設けられている。前壁部20C及び後壁部20Eは、それぞれ前後壁部の一例である。
本実施形態では、まず、センタモジュール16、フロントモジュール17及びリアモジュール18をそれぞれ製造する。例えば、センタモジュール16では、車両中央部のルーフ20B、側壁部20D及びフロアパネル21並びにセンタサイドメンバ14Aなどが組み付けられると共に、バッテリケース31がセンタサイドメンバ14Aに対して固定される。
なお、本実施形態の車両10は、車両前方に端部乗降口として前部乗降口25が設けられ、車両後方に駆動ユニット32が設けられているが、端部乗降口及び駆動ユニット32の配置は前後逆でもよい。例えば、図5に示されるように、本実施形態の変形例1の車両10Aは、車両前方に駆動ユニット32が設けられ、車両後方に端部乗降口として後部乗降口25Rが設けられている。この後部乗降口25Rは、車幅方向一端を回動可能に固定されたヒンジドア25Aにより閉塞されている。また、後部乗降口25Rには、低床部20A1から車道に向けて斜め下方に延びる端部スロープとしての後部スロープ26Rが設けられている。後部スロープ26Rは、車両10が走行する場合には、フロアパネル21の下部に設けられた後部収納部26Bに収納され、乗員が乗降する使用状態においては、後部収納部26Bから車両後方に引き出される。変形例1の場合でも本実施形態と同様の作用効果を奏する。
本実施形態の車両10は、駆動ユニット32を車両後部の車両下方に寄せて配置し、車両前方の前壁部20Cに前部乗降口25を設けている。これにより、車両前方端部から車両後方端部にかけて車室20が形成されている。ここで、車両前部において前輪24A付近は、床下にフロントアクスル13が配置されるため、低床部20A1はフロントアクスル13よりも低くすることができない。一方、車両中央部では、車両前部よりも低床化が可能であるものの、その場合、低床部20A1に段差が生じてしまう。
第2の実施形態の車両100は、駆動ユニット32及びパワーユニット34に加えて、自動運転ユニット40を車両100の車両後方に配置した点で第1の実施形態と相違する。以下、第1の実施形態との相違点を中心に説明する。なお、第1の実施形態と同一の構成には同一の符号を付している。
第3の実施形態の車両110は、第1の実施形態の車両10に対して空調システム70を構成に加えたものである。以下、第1の実施形態との相違点を中心に説明する。なお、第1の実施形態と同一の構成には同一の符号を付している。
第4の実施形態の車両120は、第3の実施形態の車両110と空調システム70の配置が相違する。以下、第3の実施形態との相違点を中心に説明する。なお、第1及び第3の実施形態と同一の構成には同一の符号を付している。
第5の実施形態の車両130は、第4の実施形態の車両120と自動運転ユニット40の配置が相違する。以下、第4の実施形態との相違点を中心に説明する。なお、第1及び第4の実施形態と同一の構成には同一の符号を付している。
第5の実施形態では、リアモジュール18におけるパワーユニット室22Aに駆動ユニット32及びパワーユニット34が収納されているが、本実施形態の変形例として、パワーユニット34をルーフモジュール19に設けてもよい。本変形例の場合、信号コネクタ48及び配管コネクタ78に加えて電力コネクタ38が、リアモジュール18とルーフモジュール19との結合部に配置される。
上述した各実施形態は運転席のない完全自動運転車であるが、これに限らず、運転席を有する自動運転車であってもよい。つまり、各実施形態は、通常は自動運転が行われ、危険回避時や任意のタイミングで手動運転を可能とすることができる。なお、運転席を車両前部における車幅方向一方側に設けることにより、前壁部20Cの車幅方向他方側に前部乗降口25を設けることができる。
