Abstract
Description
図1は、第1の実施形態に係る診断装置を備える車両の概略構成を示す図である。各車両1は、診断装置10と、ECU(Electronic Control Unit)20と、機器30と、車車間通信部40と、表示部50とを備える。説明の便宜上、図1では構成が同一の3台の車両1−1,1−2,1−3のみを示しており、本実施形態では、車両1−1を自車両(第2車両)とし、車両1−2及び車両1−3を、車両1−1から所定の範囲に存在する周辺車両(第1車両)として説明する。ここで、所定の範囲とは、例えば車車間通信が可能な範囲である。
次に、第2の実施形態に係る診断装置11について説明する。第1の実施形態の診断装置10において、車車間通信によって多くの周辺車両から検出値を取得できる場合には精度良く予兆診断を行うことができるが、周辺車両の台数が少ない場合には、異常予兆診断の精度が下がる可能性がある。ここで、アドホックネットワークや、車車間通信の転送機能などを用いて、周辺車両の通信範囲内かつ自車両の通信範囲外の車両の検出情報を、該周辺車両を経由して受け取ることも考えられる。しかし、この方法では、通信量が多くなるため、通信で使用する帯域を逼迫させてしまう。
次に、第3の実施形態に係る診断装置について説明する。第1の実施形態及び第2の実施形態では、診断装置10又は診断装置11(以下、「診断装置10(11)」と表記する。)が各車両1に搭載されている例を示したが、第3の実施形態に係る診断装置10(11)は、車両1の外部に備えられる。
次に、第4の実施形態に係る診断システムについて説明する。第4の実施形態に係る診断システムは、各車両1及びサーバ2の双方でセンサ30の診断を行うことを可能とするために、診断装置10(11)が各車両1及びサーバ2に配置される。
