Description
図1は、車両に搭載したヘッドアップディスプレイ装置(以下、HUD装置と略す)の概要を説明する模式図である。車両2に搭載されたHUD装置1は、2系統の映像表示装置30a,30bで生成したそれぞれの映像光を車両2のフロントガラス(以下、ウィンドシールド3と呼ぶ)に投射する。ウィンドシールド3で反射した映像光は運転者の目に入射し、運転者はHUDからの映像を視認する。表示する映像には運転に関連する情報が含まれ、運転操作を支援するものとなる。HUD装置1の内部は、各種の車両情報4を取得する車両情報取得部10と、これをもとに表示する映像情報を生成する制御部20と、映像光を反射する凹面ミラー41および凹面ミラー41を駆動するミラー駆動部42、運転者に音声情報を出力するスピーカ60などを有する。車両情報4には、車両の運転状態を示す速度情報やギア情報などが含まれる。
