以下、添付図面に基づいて、本発明の一実施形態を説明する。車両用表示装置は、危険対象位置情報取得手段１０１，自車位置検出手段１０２，制御手段１０３及び表示手段１０４から構成されている。   Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The vehicle display device includes a danger target position information acquisition unit 101, a host vehicle position detection unit 102, a control unit 103, and a display unit 104.

危険対象位置情報取得手段１０１は、見通しの悪い道路などにおいて、自車前方に存在する停止車両や一時停止地点等の車両運転者が注意しなければならない危険対象の位置情報を取得し、その位置情報を制御手段１０３に出力する。自車位置検出手段１０２は、ＧＰＳ（Global Positioning System）により自車の現在位置情報を取得すると共に、前記危険対象までの距離を演算して、制御手段１０３に距離情報を出力する。   The danger target position information acquisition means 101 acquires the position information of the danger target that must be noted by a vehicle driver such as a stop vehicle or a temporary stop point in front of the host vehicle on a road with poor visibility. Information is output to the control means 103. The own vehicle position detection means 102 acquires the current position information of the own vehicle by GPS (Global Positioning System), calculates the distance to the dangerous object, and outputs the distance information to the control means 103.

制御手段１０３は、危険対象位置情報取得手段１０１にて取得した危険対象の位置情報と、自車位置検出手段１０２にて得られた自車の現在位置情報とに基づいて、表示手段１０４の表示内容を変化させる。表示手段１０４は、メータ内のディスプレイ，ＨＵＤやカーナビのモニタからなるものであり、制御手段１０３で生成された表示内容を表示する。   The control means 103 displays the display on the display means 104 based on the position information of the danger object acquired by the danger object position information acquisition means 101 and the current position information of the own vehicle obtained by the own vehicle position detection means 102. Change the content. The display means 104 includes a display in the meter, a HUD or a car navigation monitor, and displays the display contents generated by the control means 103.

次に、図２に基づいて、表示手段１０４に表示される表示形態の変化について詳述する。
３０１は自車であり、３０２は自車が向かう先に存在する停止車両（危険対象）である。制御手段１０３は、情報提示を開始する地点３０８から危険対象位置までを３つの区間３０３，３０４，３０５に分割する。
制御手段１０３は、表示手段１０４に表示される表示部２０２ａ〜２０２ｃの移動速度を変化させる位置３０６，３０７を算出し、その位置３０６，３０７に到達したとき、表示部２０２ａ〜２０２ｃの拡大速度を変化させる。 Next, a change in the display form displayed on the display unit 104 will be described in detail with reference to FIG.
Reference numeral 301 denotes a host vehicle, and reference numeral 302 denotes a stopped vehicle (danger target) that exists at the destination of the host vehicle. The control means 103 divides the area from the point 308 where information presentation starts to the danger target position into three sections 303, 304, and 305.
The control means 103 calculates the positions 306 and 307 for changing the moving speeds of the display units 202a to 202c displayed on the display means 104, and when reaching the positions 306 and 307, the enlargement speed of the display parts 202a to 202c is calculated. Change.

自車３０１が地点３０８に到達したとき、表示手段１０４の画面には、危険対象の内容を示すアイコン２０１と、危険対象までの到達時間を示す表示部２０２ａ〜２０２ｃとが表示される（図３参照）。表示部２０２ａ〜２０２ｃは、画面中央から画面外側に向けて連続的に拡大し、最も外側まで拡大した後は、再び画面中央から拡大し始め、これを繰り返す。
自車３０１が区間３０５に位置しているとき、表示部２０２ａ〜２０２ｃの移動速度は最も遅い速度であり、表示部２０２ａが画面中央に出現してから、最も外側まで拡大した表示部２０２ｃが表示されるまでの周期は１．５秒である。 When the host vehicle 301 reaches the point 308, an icon 201 indicating the contents of the dangerous object and display units 202a to 202c indicating the arrival time to the dangerous object are displayed on the screen of the display unit 104 (FIG. 3). reference). The display units 202a to 202c continuously expand from the center of the screen toward the outside of the screen, and after expanding to the outermost side, start to expand again from the center of the screen and repeat this.
When the host vehicle 301 is located in the section 305, the moving speed of the display sections 202a to 202c is the slowest speed, and the display section 202c expanded to the outermost side after the display section 202a appears at the center of the screen is displayed. The period until it is done is 1.5 seconds.

自車３０１が停止車両３０２に近づいて、地点３０７に到達したとき、表示部２０２ａ〜２０２ｃの表示拡大周期は短くなり、１秒になる。その後、自車３０１が地点３０６に到達したとき、表示部２０２ａ〜２０２ｃの表示拡大周期は更に短くなり、周期は０．５秒になる。自車３０１が停止車両３０２の周辺に到達したときには、車両運転者は停止車両３０２が見えているため、表示を停止する。   When the host vehicle 301 approaches the stop vehicle 302 and reaches the point 307, the display expansion period of the display units 202a to 202c is shortened to 1 second. Thereafter, when the host vehicle 301 reaches the point 306, the display enlargement cycle of the display units 202a to 202c is further shortened, and the cycle is 0.5 seconds. When the own vehicle 301 reaches the periphery of the stop vehicle 302, the vehicle driver stops the display because the stop vehicle 302 is visible.

以上説明したように、表示部２０２ａ〜２０２ｃが画面中央に出現してから最も外側に拡大するまでの時間は、自車位置から危険対象の位置までを複数に分割した区間３０３，３０４，３０５によって変化し、自車３０１が危険対象に近い区間に入る毎に、マーク２０２ａ〜２０２ｃが移動する速度が速くなる。つまり、自車３０１が区間３０５に位置しているとき、表示拡大周期は１．５秒、自車３０１が区間３０４に位置しているとき、表示拡大周期は１秒、自車３０１が区間３０３に位置しているとき、表示拡大周期は０．５秒である。   As described above, the time from when the display units 202a to 202c appear in the center of the screen until the display parts 202a to 202c expand outward is determined by the sections 303, 304, and 305 that are divided from the vehicle position to the position of the danger target. The speed at which the marks 202a to 202c move increases each time the vehicle 301 enters a section close to the danger target. That is, when the own vehicle 301 is located in the section 305, the display enlargement cycle is 1.5 seconds, when the own vehicle 301 is located in the section 304, the display enlargement cycle is 1 second, and the own vehicle 301 is in the section 303. When positioned at, the display magnification period is 0.5 seconds.

人間の視覚特性において、周辺視野では細かいものを見ることは困難であるが動くものには反応できるため、運転中に視線を前方に向けた状態においても、周辺視野で動く表示部２０２ａ〜２０２ｃの動きと変化速度によって、危険対象までの到達時間が短くなっていることを認識することが可能となる。   In human visual characteristics, it is difficult to see a fine thing in the peripheral visual field, but it can react to moving objects. Therefore, even when the line of sight is directed forward during driving, the display units 202a to 202c that move in the peripheral visual field It is possible to recognize that the arrival time to the dangerous object is shortened by the movement and the change speed.

本実施形態によれば、表示手段１０４の画面に表示された表示部２０２ａ〜２０２ｃが動く速度とその変化速度によって危険対象までの予測到達時間を車両運転者に伝えるため、周辺視野で動体を検出できる人間の視覚特性上、表示を注視しなくとも視界の隅で予測到達時間を表す表示の動き変化を把握でき、表示を見ることによる注意散漫を軽減することができ、安全運転に寄与することができる。なお、表示形態の変化は、例えば、色変化、明るさ変化または大きさ変化であっても良い。   According to this embodiment, a moving object is detected in the peripheral visual field in order to inform the vehicle driver of the predicted arrival time to the danger target by the speed at which the display units 202a to 202c displayed on the screen of the display unit 104 move and the change speed thereof. It is possible to grasp the change in the display movement that represents the estimated arrival time at the corner of the field of view without having to pay attention to the display, and to reduce distraction from seeing the display, contributing to safe driving Can do. Note that the change in the display form may be, for example, a color change, a brightness change, or a size change.
