Abstract
Description
実施形態に係る車両用表示装置について説明する。図1は、実施形態に係る車両用表示装置を搭載した車両の概略構成を示す模式図である。図2は、実施形態に係る車両用表示装置の概略構成を示すブロック図である。図3は、実施形態におけるアイポイントと虚像表示領域との位置関係を示す模式図である。図4は、実施形態における車両の進行方向から見た表示領域の一例を示す模式図である。図5は、実施形態に係る車両用表示装置によりウインドシールドに投影された表示画像に対応する虚像の一例を示す模式図である。図6は、実施形態における運転者の視認範囲と虚像表示領域との位置関係を示す模式図である。図7は、実施形態におけるアイポイント右方向移動時の視認領域の変化を示す模式図である。図8は、実施形態におけるアイポイント左方向移動時の視認領域の変化を示す模式図である。図9(A)〜図9(C)は、虚像表示領域に表示される外部情報虚像の一例を示す模式図である。なお、図3、図6〜図8(図12を含む)における光軸Oは、後述する反射ミラー31の光軸である。
その後、他の車両が右方向から左方向に移動すると、制御部12は、外部情報虚像Soの表示を、左単眼視認領域23aから両眼視認領域21に切り替える。このとき、外部情報虚像Soは、変化後の視認領域に対応した表示態様となるように、視認性表示態様から識別性表示態様に切り替わる。
