を備える車両ルーフ構造。
本実施形態のルーフパネルは、車両用のルーフパネルであって、厚み方向と直交する方向に分割され、分割された部材の一部又は全部が樹脂製である。以下、ルーフパネルの具体例を、図面を参照しながら説明するが、本開示はこれに限定されるものではない。
また、本実施形態では、ライダ34をカメラ36の下方に近接して配置しているが、本開示はこの構成に限定されるものでない。ライダ34及びカメラ36は、それぞれを有効利用可能な位置(例えば、車両幅方向の中央部)に配置することが好ましい。
本実施形態の車両ルーフ構造は、車両のルーフ部を構成する上記ルーフパネルと、車室の天井を構成する天井内装材と、前記ルーフパネルと前記天井内装材との間であって樹脂製の分割された部材に対応する位置に取り付けられる車載機器と、を備えている。以下、車両ルーフ構造の具体例を、図面を参照しながら説明するが、本開示はこれに限定されるものではない。
従来公知の全部が金属製のルーフパネルでは、電波を反射するため、電波通信を行う車載機器26をルーフパネルと天井内装材44との間に配置できない。これに対して、本実施形態のルーフパネル20では、分割されたパネル部材22とパネル部材24のうち、パネル部材22を樹脂製としている。このため、ルーフパネル20のパネル部材22に対応する部分においては電波が透過する。このパネル部材22に対応する部分に電波通信を行う車載機器26としてGPSアンテナ28や無線アンテナ30、電波を照射する車載機器26であるミリ波レーダ32等を配置することで、ルーフパネル20のパネル部材22に対応する部分を透過して電波通信又は電波照射を行うことができる。ここで、ミリ波レーダ32をルーフ部42に配置することで、広範囲にミリ波を照射することが可能となる。
特に、ルーフパネル20では、樹脂製のパネル部材22が車両前方側に位置するため、ルーフ部42の車両前方側が電波透過性に優れる。このため、電波を照射する車載機器26(ミリ波レーダ32)をルーフ部42の車両前方側に配置することで、ミリ波レーダ32からの電波がパネル部材22を透過して車体前方へ照射される。これにより、広い範囲で正確に、車両に対する障害物の距離及び方向を求めることが可能になる。
本明細書に記載された全ての文献、特許出願、および技術規格は、個々の文献、特許出願、および技術規格が参照により取り込まれることが具体的かつ個々に記された場合と同程度に、本明細書中に参照により取り込まれる。
