Description

車両用情報表示装置及び車両用情報表示方法Vehicle information display device and vehicle information display method
　本発明は、車両周辺に位置する対象物の情報を表示する車両用情報表示装置及び車両用情報表示方法に関する。 The present invention relates to a vehicle information display device and a vehicle information display method for displaying information on an object located around the vehicle.
　車両用情報表示装置は、車両の周辺に存在する対象物を検出して表示する装置である。特開２０１１－１０８１１０号公報には、他車両の位置情報を取得すると共に、他車両の存在をディスプレイに表示させる無線装置が開示されている。この無線装置では、ディスプレイの縁近傍に設けられた表示エリアに他車両を表示させる。よって、運転者に対象物の存在を確実に伝えることができ、注意喚起を行えるようになっている。 The vehicle information display device is a device that detects and displays an object present around the vehicle. Japanese Patent Application Laid-Open No. 2011-108110 discloses a wireless device that acquires position information of another vehicle and displays the presence of the other vehicle on a display.

Therefore, the driver can be surely notified of the presence of the object and can be alerted.
特開２０１１－１０８１１０号公報JP 2011-108110 A
　しかしながら、上述したような表示装置においては、対象物を検出することができても、検出した対象物が表示装置において表示領域の外に位置する場合には、対象物を表示装置で表示できないという問題がある。このように、対象物が表示領域の外に位置する場合には対象物を表示できないので、運転者が対象物の存在に気付くタイミングが遅れるという問題がある。 However, in the display device as described above, even if the object can be detected, the object cannot be displayed on the display device when the detected object is located outside the display area in the display device. There's a problem. Thus, since the target object cannot be displayed when the target object is located outside the display area, there is a problem that the timing when the driver notices the presence of the target object is delayed.
　また、対象物が表示領域の外に位置していても、表示領域を拡大又は移動させれば対象物を表示させることは可能となる。しかし、対象物の位置の変化に応じてその都度、表示領域を拡大又は移動させると、表示装置の視認性においてドライバに煩わしさを生じさせるという問題を生じさせる可能性がある。 In addition, even if the object is located outside the display area, it is possible to display the object by enlarging or moving the display area. However, if the display area is enlarged or moved each time according to the change in the position of the object, there is a possibility that the driver may become troublesome in the visibility of the display device.
　そこで、本発明の課題は、表示領域を拡大又は移動させなくても、表示領域の外に位置する対象物の情報を表示させることができる車両用情報表示装置及び車両用情報表示方法を提供することである。 Therefore, an object of the present invention is to provide a vehicle information display device and a vehicle information display method that can display information on an object located outside the display area without enlarging or moving the display area. That is.
　すなわち、本発明に係る車両用情報表示装置は、自車両の周辺に位置する対象物の位置情報を取得する対象物位置情報取得部と、対象物位置情報取得部によって取得された対象物の位置情報又は自車両に対する方向情報の少なくとも何れかに係るイメージを対象物の位置に応じて表示領域に表示させるものであって、表示領域内に表示される位置に対象物が位置する場合と、表示領域内に表示されない位置に対象物が位置する場合とで、表示領域内における表示態様を異ならせてイメージを表示させる表示部と、を備える。 That is, the vehicle information display device according to the present invention includes an object position information acquisition unit that acquires position information of an object located in the vicinity of the host vehicle, and an object position acquired by the object position information acquisition unit. An image related to at least one of information or direction information with respect to the host vehicle is displayed on the display area according to the position of the object, and the display is performed when the object is located at a position displayed in the display area. And a display unit that displays an image by changing a display mode in the display area when the object is located at a position not displayed in the area.
　本発明に係る車両用情報表示装置において、表示部は、表示領域内に表示される位置に対象物が位置する場合と、表示領域内に表示されない位置に対象物が位置する場合とで、表示領域内における表示態様を異ならせて上述したイメージを表示させる。よって、表示領域内に表示されない箇所に位置する対象物の情報を表示させることができる。また、表示領域を拡大又は移動しなくても表示領域内に表示されない対象物の情報を表示させることができるので、表示装置の視認性においてドライバに煩わしさを生じさせるという事態を回避することができる。 In the vehicle information display device according to the present invention, the display unit displays the case where the object is located at a position displayed in the display area and the case where the object is located at a position not displayed in the display area. The above-described image is displayed with different display modes in the area. Therefore, it is possible to display information on an object located at a location that is not displayed in the display area. In addition, since it is possible to display information on an object that is not displayed in the display area without enlarging or moving the display area, it is possible to avoid a situation in which the driver is bothered by the visibility of the display device. it can.
　また、本発明に係る車両用情報表示装置において、表示部は、表示領域内に表示される位置に対象物が位置する場合には対象物の情報を対象物の位置に関する情報として表示領域内に表示し、表示領域内に表示されない位置に対象物が位置する場合には対象物の情報を対象物の方向に関する情報として表示領域内に表示してもよい。このように、対象物が表示領域内に表示されるときは対象物の情報を位置情報として表示し、対象物が表示領域内に表示されないときは対象物の情報を方向情報として表示する。よって、対象物が表示領域内に表示されるか否かに拘らず、自車両の搭乗者は対象物の位置を把握することができる。 Further, in the vehicle information display device according to the present invention, the display unit includes information on the object in the display area as information on the position of the object when the object is located at a position displayed in the display area. When the object is displayed at a position that is not displayed in the display area, the information on the object may be displayed in the display area as information on the direction of the object. Thus, when the target object is displayed in the display area, the target object information is displayed as position information, and when the target object is not displayed in the display area, the target object information is displayed as direction information. Therefore, regardless of whether or not the object is displayed in the display area, the passenger of the own vehicle can grasp the position of the object.
　また、表示部は、表示領域内に表示されない位置に対象物が位置する場合には、対象物が位置する方向を示す図形で対象物の情報を表示してもよい。このように、表示領域内に表示されない位置に対象物が存在する場合に、対象物が位置する方向を示す図形で対象物の情報を表示することにより、自車両の搭乗者は、表示領域外の対象物の位置をより確実に把握することができる。 In addition, when the target object is located at a position that is not displayed in the display area, the display unit may display information on the target object with a graphic indicating the direction in which the target object is positioned.

In the following description, the same or equivalent elements will be denoted by the same reference numerals, and redundant description will be omitted.
　図１に示されるように、本実施形態に係る車両用情報表示装置１は、車両１００に搭載されており、車両１００周辺の対象物を検出して表示系ＨＭＩ（Human　Machine　Interface）である表示部３０の表示領域３１（図３参照）に表示させる。車両１００周辺の対象物としては、例えば、車両１００の前方に位置する歩行者、自転車又は車両１００以外の他車両が挙げられる。 As shown in FIG. 1, the vehicle information display device 1 according to the present embodiment is mounted on a vehicle 100 and detects an object around the vehicle 100 to display a display system HMI (Human Machine Interface). It is displayed on the display area 31 (see FIG. 3) of the unit 30. Examples of the object around the vehicle 100 include a pedestrian, a bicycle, or a vehicle other than the vehicle 100 located in front of the vehicle 100.
　車両用情報表示装置１は、自車両である車両１００の周辺に位置する対象物の位置情報を取得する物体検出センサ（対象物位置情報取得部）１０と、物体検出センサ１０によって検出された対象物の位置情報又は車両１００に対する対象物の方向情報の少なくとも何れかに係るイメージを対象物の位置に応じて表示領域３１に表示させる表示部３０と、を備えている。本実施形態において表示領域３１は、車両１００内から前方を見た場合におけるフロントガラス３５の右側に配置されたヘッドアップディスプレイであり、車両１００の運転者が運転中に視認可能となっている。表示部３０は、表示領域３１内に表示される位置に対象物が位置する場合と、表示領域３１内に表示されない位置に対象物が位置する場合とで、表示領域３１内における表示態様を異ならせて上記のイメージを表示させる。ここで、上記のイメージは、画面上に表示される数値等とは異なり、ヘッドアップディスプレイ装置においてフロントガラス３５上に投影される光や意匠を示している。 The vehicle information display device 1 includes an object detection sensor (object position information acquisition unit) 10 that acquires position information of an object located around the vehicle 100 that is the host vehicle, and an object detected by the object detection sensor 10. A display unit 30 that displays an image related to at least one of the position information of the object and the direction information of the object with respect to the vehicle 100 in a display area 31 according to the position of the object. In the present embodiment, the display area 31 is a head-up display disposed on the right side of the windshield 35 when looking forward from within the vehicle 100 and is visible to the driver of the vehicle 100 while driving. The display unit 30 changes the display mode in the display area 31 between the case where the object is located at a position displayed in the display area 31 and the case where the object is located at a position not displayed in the display area 31. Display the above image. Here, unlike the numerical value etc. which are displayed on a screen, said image has shown the light and design which are projected on the windshield 35 in a head-up display apparatus.
　物体検出センサ１０は、車両１００周辺の物体を対象物として検出するセンサであり、特に障害物となり得る物体の有無を検出する。物体検出センサ１０は、例えば、車両１００の周辺に電磁波を送信し、物体から反射される電磁波を受信することによって対象物を検出する。物体検出センサ１０としては、例えばミリ波レーダやレーザレーダ等を用いることが可能である。 The object detection sensor 10 is a sensor that detects an object around the vehicle 100 as a target, and particularly detects the presence or absence of an object that can be an obstacle. For example, the object detection sensor 10 transmits an electromagnetic wave to the periphery of the vehicle 100 and detects an object by receiving the electromagnetic wave reflected from the object. As the object detection sensor 10, for example, a millimeter wave radar, a laser radar, or the like can be used.
　物体検出センサ１０には表示部３０による画面表示を制御するＥＣＵ（Electronic　Control　Unit）２０が接続されており、ＥＣＵ２０には表示部３０が接続されている。物体検出センサ１０によって取得された対象物の位置情報は、ＥＣＵ２０に出力される。ＥＣＵ２０は、対象物の位置情報を座標変換する座標変換部２１と、対象物が表示領域３１内に表示されるか否かを判断する対象物表示位置判断部２２と、を備えて構成されている。ＥＣＵ２０は、ＣＰＵ、ＲＯＭ、ＲＡＭ等を備えて構成されており、ＣＰＵによるプログラムの実行を通じて、座標変換部２１及び対象物表示位置判断部２２の機能を実現する。なお、座標変換部２１及び対象物表示位置判断部２２の機能は、複数のＥＣＵによって実現されてもよい。 The object detection sensor 10 is connected to an ECU (Electronic Control Unit) 20 that controls screen display by the display unit 30, and the ECU 20 is connected to the display unit 30. The position information of the object acquired by the object detection sensor 10 is output to the ECU 20. The ECU 20 includes a coordinate conversion unit 21 that performs coordinate conversion of position information of the object, and an object display position determination unit 22 that determines whether or not the object is displayed in the display area 31. Yes. The ECU 20 includes a CPU, a ROM, a RAM, and the like, and realizes the functions of the coordinate conversion unit 21 and the object display position determination unit 22 through execution of a program by the CPU. The functions of the coordinate conversion unit 21 and the object display position determination unit 22 may be realized by a plurality of ECUs.
　図２に示されるように、座標変換部２１は、物体検出センサ１０によって検出された対象物Ｔ１の位置を、フロントガラス３５越しに投影したときの座標に変換する。座標変換部２１は、例えば、車両１００の運転者Ｄの目Ｅでフロントガラス３５を介して対象物Ｔ１を見た場合におけるフロントガラス３５上の対象物Ｔ１の位置座標（Ｘ，Ｙ）を取得する。 As shown in FIG. 2, the coordinate conversion unit 21 converts the position of the target T1 detected by the object detection sensor 10 into coordinates when projected through the windshield 35. The coordinate conversion unit 21 acquires, for example, the position coordinates (X, Y) of the object T1 on the windshield 35 when the object T1 is viewed through the windshield 35 with the eye E of the driver D of the vehicle 100. To do.
　なお、座標変換部２１によって取得される対象物の位置座標は、フロントガラス３５上の座標に限られず、車両１００の搭乗者に対象物の存在を知らせる装置における表示領域上の座標であればよい。また、座標変換部２１による座標変換の手法は上記に限られず、２次元平面上における対象物Ｔ１の位置を取得できれば別の手法を用いてもよい。 Note that the position coordinates of the object acquired by the coordinate conversion unit 21 are not limited to the coordinates on the windshield 35, but may be coordinates on the display area in the device that notifies the passenger of the vehicle 100 of the presence of the object. . Further, the method of coordinate conversion by the coordinate conversion unit 21 is not limited to the above, and another method may be used as long as the position of the target T1 on the two-dimensional plane can be acquired.
　対象物表示位置判断部２２は、フロントガラス３５上における対象物Ｔ１の位置が表示領域３１内であるか否かを判断する。具体的には、図３及び図４に示されるように、物体検出センサ１０による対象物の検出可能領域であって且つ対象物が表示領域３１内に表示される領域を領域Ａ、物体検出センサ１０による対象物の検出可能領域であって且つ対象物が表示領域３１内に表示されない領域を領域Ｂ、とすると、対象物表示位置判断部２２は、対象物Ｔ１が領域Ａ及び領域Ｂのいずれに位置するかを判断する。ここで、領域Ａと領域Ｂとは、予め設定された境界を隔てて分けられており、例えばフロントガラス３５上に同フロントガラス３５の一部分として領域Ｂが設定される。 The object display position determination unit 22 determines whether or not the position of the object T1 on the windshield 35 is within the display area 31. Specifically, as shown in FIG. 3 and FIG. 4, an area where the object can be detected by the object detection sensor 10 and the area where the object is displayed in the display area 31 is an area A, the object detection sensor. 10, the region in which the target object is detectable and the region in which the target object is not displayed in the display region 31 is defined as region B. The target object display position determination unit 22 determines whether the target object T1 is either the region A or the region B. To determine if it is located at. Here, the region A and the region B are separated from each other by a predetermined boundary. For example, the region B is set as a part of the windshield 35 on the windshield 35.
　表示部３０は、対象物表示位置判断部２２によって対象物が領域Ａに位置すると判断された場合と、対象物表示位置判断部２２によって対象物が領域Ｂに位置すると判断された場合とで、表示領域３１に表示させる対象物の表示態様を異ならせる。表示部３０は、領域Ａに位置する対象物Ｔ１については対象物Ｔ１の位置に関する情報をイメージとして表示領域３１に表示し、領域Ｂに位置する対象物Ｔ２については対象物Ｔ２の方向に関する情報をイメージとして表示領域３１に表示する。具体的には、領域Ａに位置する対象物Ｔ１については、対象物Ｔ１を囲む矩形の図形３２によって対象物Ｔ１を強調表示し、領域Ｂに位置する対象物Ｔ２については、対象物Ｔ２の方向を向く矢印３３によって対象物Ｔ２の情報を表示する。 The display unit 30 includes a case where the object display position determination unit 22 determines that the object is located in the region A and a case where the object display position determination unit 22 determines that the object is located in the region B. The display mode of the object displayed in the display area 31 is changed. The display unit 30 displays information about the position of the target object T1 as an image on the display area 31 for the target object T1 located in the area A, and information about the direction of the target object T2 about the target object T2 located in the area B. The image is displayed in the display area 31 as an image. Specifically, for the target T1 located in the region A, the target T1 is highlighted by a rectangular figure 32 surrounding the target T1, and for the target T2 located in the region B, the direction of the target T2 The information of the target object T2 is displayed by the arrow 33 facing.
　次に、本実施形態に係る車両用情報表示方法について図５を参照して説明する。図５に示されるフローチャートは、車両用情報表示装置１を用いて行われる車両用情報表示処理のフローを示している。この車両用情報表示処理は、例えば一定時間ごとに繰り返し実行される。 Next, the vehicle information display method according to the present embodiment will be described with reference to FIG. The flowchart shown in FIG. 5 shows a flow of a vehicle information display process performed using the vehicle information display device 1. This vehicle information display process is repeatedly executed, for example, at regular intervals.
　まず、ステップＳ１１（以下、「Ｓ１１」という。他のステップにおいても同様とする）では、物体検出センサ１０によって対象物位置情報取得処理（対象物位置情報取得ステップ）が実行される。Ｓ１１では、物体検出センサ１０によって車両１００の周辺に対象物が存在するか否かが検出され、例えば領域Ａ又は領域Ｂ内に対象物が存在するか否かが判定される。Ｓ１１で車両１００の周辺に対象物が存在しないと判定された場合には一連の処理を終了し、Ｓ１１で車両１００の周辺に対象物が存在すると判定された場合にはＳ１２に移行する。 First, in step S11 (hereinafter referred to as “S11”, the same applies to other steps), the object position sensor 10 performs an object position information acquisition process (object position information acquisition step). In S <b> 11, it is detected whether or not an object exists around the vehicle 100 by the object detection sensor 10, and for example, it is determined whether or not the object exists in the area A or the area B. If it is determined in S11 that there is no object around the vehicle 100, the series of processes is terminated. If it is determined in S11 that the object exists around the vehicle 100, the process proceeds to S12.
　Ｓ１２では座標変換部２１によって対象物位置推定処理が実行され、その後のＳ１３では座標変換部２１によって座標変換処理が実行される。具体的には、Ｓ１２で対象物の位置座標が算出され、算出された位置座標は、Ｓ１３でフロントガラス３５上の位置座標に変換される。 In S12, the object position estimation process is executed by the coordinate conversion unit 21, and in the subsequent S13, the coordinate conversion process is executed by the coordinate conversion unit 21. Specifically, the position coordinates of the object are calculated in S12, and the calculated position coordinates are converted into position coordinates on the windshield 35 in S13.
　対象物の位置座標がフロントガラス３５上の位置座標に変換された後はＳ１４に移行し、変換された位置座標が表示領域３１内であるか否かが判定される。このＳ１４の処理は、対象物表示位置判断部２２によって実行される。Ｓ１４において、フロントガラス３５上における対象物の位置座標が表示領域３１内である場合はＳ１５に移行し、フロントガラス３５上における対象物の位置座標が表示領域３１外である場合はＳ１６に移行する。 After the position coordinates of the object are converted into the position coordinates on the windshield 35, the process proceeds to S14, and it is determined whether or not the converted position coordinates are within the display area 31. The process of S14 is executed by the object display position determination unit 22. In S14, when the position coordinates of the object on the windshield 35 are within the display area 31, the process proceeds to S15, and when the position coordinates of the object on the windshield 35 is outside the display area 31, the process proceeds to S16. .
　Ｓ１５では、対象物の位置に関する情報のイメージを表示する対象物位置情報表示処理が表示部３０によって実行される（表示ステップ）。具体的には、例えば図３に示されるように、表示領域３１内の対象物Ｔ１を図形３２で囲んで強調表示し、対象物Ｔ１の位置情報に係るイメージを表示する処理が実行される。一方、Ｓ１６では、対象物の方向に関する情報のイメージを表示する対象物方向情報表示処理が表示部３０によって実行される（表示ステップ）。具体的には、例えば図４に示されるように、対象物Ｔ２の方向を向く矢印３３によって対象物Ｔ２の方向情報に係るイメージを表示する処理が実行される。このように、Ｓ１５又はＳ１６の処理が実行された後に一連の処理が終了する。 In S15, an object position information display process for displaying an image of information related to the position of the object is executed by the display unit 30 (display step). Specifically, for example, as shown in FIG. 3, the object T1 in the display area 31 is highlighted by surrounding it with a graphic 32, and a process for displaying an image related to position information of the object T1 is executed. On the other hand, in S16, object direction information display processing for displaying an image of information relating to the direction of the object is executed by the display unit 30 (display step). Specifically, for example, as illustrated in FIG. 4, a process of displaying an image related to the direction information of the target object T2 is performed by an arrow 33 that faces the direction of the target object T2. In this way, a series of processing ends after the processing of S15 or S16 is executed.
　以上のように、本実施形態の車両用情報表示装置１及び車両用情報表示方法において、表示部３０は、表示領域３１内に表示される対象物Ｔ１と表示領域３１内に表示されない対象物Ｔ２とで、表示領域３１内における表示態様を異ならせて対象物の位置情報又は方向情報に係るイメージを表示させる。よって、例えば上述したような矢印３３により、表示領域３１内に表示されない対象物Ｔ２の情報を表示領域３１に表示させることができる。また、表示領域３１を拡大又は移動しなくても対象物Ｔ２の情報を表示させることができるので、表示装置の視認性においてドライバに煩わしさを生じさせるという事態を回避することができる。 As described above, in the vehicle information display device 1 and the vehicle information display method of the present embodiment, the display unit 30 includes the object T1 displayed in the display area 31 and the object T2 not displayed in the display area 31. Thus, an image relating to the position information or the direction information of the object is displayed by changing the display mode in the display area 31. Therefore, for example, by the arrow 33 as described above, information on the object T2 that is not displayed in the display area 31 can be displayed in the display area 31. In addition, since the information on the target T2 can be displayed without enlarging or moving the display area 31, it is possible to avoid a situation in which the driver is bothered by the visibility of the display device.
　また、車両用情報表示装置１では、表示領域３１内に表示される対象物Ｔ１は対象物Ｔ１の位置情報として表示され、表示領域３１内に表示されない対象物Ｔ２は対象物Ｔ２の方向情報として表示される。よって、対象物が表示領域３１内に位置するか否かに拘らず、車両１００の搭乗者は対象物の位置を把握することができる。 In the vehicle information display device 1, the target object T1 displayed in the display area 31 is displayed as position information of the target object T1, and the target object T2 not displayed in the display area 31 is used as direction information of the target object T2. Is displayed. Therefore, regardless of whether or not the object is located in the display area 31, the passenger of the vehicle 100 can grasp the position of the object.
　また、車両用情報表示装置１において、表示領域３１内に表示されない位置に存在する対象物Ｔ２にあっては、対象物Ｔ２が位置する方向を示す矢印３３等の図形で対象物Ｔ２の情報を表示する。よって、車両１００の搭乗者は、表示領域３１外の対象物Ｔ２の位置をより確実に把握することができる。 Further, in the vehicle information display device 1, for the target T2 that is present at a position that is not displayed in the display area 31, the information on the target T2 is indicated by a graphic such as an arrow 33 that indicates the direction in which the target T2 is positioned. indicate. Therefore, the passenger of the vehicle 100 can more reliably grasp the position of the object T2 outside the display area 31.
　また、車両用情報表示装置１において、表示領域３１は、車両１００のヘッドアップディスプレイ上に設けられている。よって、対象物の情報は、車両１００の搭乗者の略視線上に表示されるので、車両１００の搭乗者は、視線をほとんど移動させなくても対象物の位置を把握することが可能となる。従って、搭乗者が対象物の存在に気付くタイミングを早めることができ、搭乗者は、対象物に対する対処行動（例えば、減速や操舵等）を素早く実施できるようになる。 In the vehicle information display device 1, the display area 31 is provided on the head-up display of the vehicle 100. Therefore, since the information on the target object is displayed on the approximate line of sight of the passenger of the vehicle 100, the passenger of the vehicle 100 can grasp the position of the target object with little movement of the line of sight. . Therefore, the timing at which the occupant notices the presence of the object can be advanced, and the occupant can quickly perform coping behavior (for example, deceleration, steering, etc.) on the object.
　なお、上述した実施形態は本発明に係る車両用情報表示装置及び車両用情報表示方法の実施形態を説明したものであり、本発明に係る車両用情報表示装置及び車両用情報表示方法は本実施形態に記載されたものに限定されない。本発明に係る車両用情報表示装置及び車両用情報表示方法は、各請求項に記載した要旨を変更しないように本実施形態に係る車両用情報表示装置及び車両用情報表示方法を変形し、又は他のものに適用したものであってもよい。 The above-described embodiment is a description of the embodiment of the vehicle information display device and the vehicle information display method according to the present invention, and the vehicle information display device and the vehicle information display method according to the present invention is the present embodiment. It is not limited to what was described in the form. The vehicle information display device and the vehicle information display method according to the present invention are modified from the vehicle information display device and the vehicle information display method according to the present embodiment so as not to change the gist described in each claim, or It may be applied to other things.
　例えば、上記実施形態では、対象物Ｔ１を囲む矩形の図形３２によって対象物Ｔ１を強調表示し、対象物Ｔ２の方向を向く矢印３３によって対象物Ｔ２を表示したが、対象物を表示する態様は図形３２及び矢印３３に限定されない。例えば、図６（ａ）に示されるように、対象物Ｔ３側に位置する表示領域３１の辺の一部４３を強調表示することによって表示領域３１外に位置する対象物Ｔ３の情報を表示してもよい。また、図６（ｂ）に示されるように、対象物Ｔ４の上部に三角形状の図形４２を表示することによって表示領域３１内に位置する対象物Ｔ４の情報を強調表示してもよい。 For example, in the above embodiment, the target object T1 is highlighted by the rectangular figure 32 surrounding the target object T1, and the target object T2 is displayed by the arrow 33 facing the direction of the target object T2. It is not limited to the figure 32 and the arrow 33. For example, as shown in FIG. 6A, the information on the object T3 located outside the display area 31 is displayed by highlighting a part 43 of the side of the display area 31 located on the object T3 side. May be. Further, as shown in FIG. 6B, information on the target T4 located in the display area 31 may be highlighted by displaying a triangular figure 42 on the upper side of the target T4.
　また、図６（ｃ）及び図６（ｄ）に示されるように、対象物Ｔ５の方向を向く矢印５３によって表示領域３１外に位置する対象物Ｔ５の情報を表示してもよく、対象物Ｔ６の下半分を囲むように設けられた図形５２によって表示領域３１内に位置する対象物Ｔ６の情報を表示してもよい。更に、図６（ｅ）及び図６（ｆ）に示されるように、対象物Ｔ５の移動に伴って矢印５３の向きを対象物Ｔ５を追うように変更してもよい。 Moreover, as shown in FIG. 6C and FIG. 6D, information on the target T5 located outside the display region 31 may be displayed by an arrow 53 pointing in the direction of the target T5. Information on the object T6 located in the display area 31 may be displayed by a graphic 52 provided so as to surround the lower half of T6. Further, as shown in FIGS. 6E and 6F, the direction of the arrow 53 may be changed to follow the target T5 as the target T5 moves.
　また、図７（ａ）～図７（ｃ）に示されるように、表示領域３１外に位置する対象物Ｔ７の情報を表示する態様として、対象物Ｔ７に向かうに従って広がる三角形状の図形６２を表示領域３１内で表示させてもよい。そして、上記の矢印５３と同様に、図形６２の向きを対象物Ｔ７を追うように変更してもよい。要は、対象物が表示領域３１内に位置する場合と、対象物が表示領域３１外に位置する場合とで表示態様が異なっていればよく、各対象物の情報を表示する図形（イメージ）の形状や色彩等は適宜変更させることができる。 Further, as shown in FIGS. 7A to 7C, as a mode for displaying information on the object T7 located outside the display area 31, a triangular figure 62 that spreads toward the object T7 is displayed. It may be displayed in the display area 31. Then, like the arrow 53 described above, the orientation of the figure 62 may be changed to follow the object T7. In short, it is sufficient that the display mode is different between the case where the object is located within the display area 31 and the case where the object is located outside the display area 31, and a graphic (image) for displaying information on each object. The shape, color, etc. can be changed as appropriate.
　また、図８（ａ）及び図８（ｂ）に示されるように、表示領域３１外で移動する対象物Ｔ９，Ｔ１０の情報を表示する態様として、対象物Ｔ９の情報を表示する矢印７３よりも、対象物Ｔ９より速く移動する対象物Ｔ１０の情報を表示する矢印７４を長くしてもよい。また、より速く移動する対象物の情報をより大きな図形で表示してもよい。このように、対象物の速度に応じて表示領域３１における表示態様を変えてもよい。また、車両１００に近い箇所に位置する対象物を大きな図形で表示すると共に、車両１００から遠い箇所に位置する対象物を小さな図形で表示してもよく、このように、車両１００からの対象物の距離に応じて表示態様を変えてもよい。 Further, as shown in FIGS. 8A and 8B, as an aspect of displaying information on the objects T9 and T10 that move outside the display area 31, an arrow 73 that displays information on the object T9 is used. Alternatively, the arrow 74 for displaying information on the target T10 that moves faster than the target T9 may be lengthened. In addition, information on an object that moves faster may be displayed in a larger figure. Thus, the display mode in the display area 31 may be changed according to the speed of the object. In addition, the object located near the vehicle 100 may be displayed as a large graphic, and the object located far from the vehicle 100 may be displayed as a small graphic. Thus, the object from the vehicle 100 may be displayed. The display mode may be changed according to the distance.
　更に、物体検出センサ１０によって検出された対象物の種類、対象物の位置又は対象物の速度から対象物の危険度を算出し、算出した危険度に応じて表示態様を変えてもよい。具体的には、危険度が高い対象物を赤色、危険度が中程度の対象物を黄色、危険度が低い対象物を青色の図形等で表示してもよい。ここで、対象物の種類としては、例えば、歩行者か若しくは車両か、又は成人か若しくは子供か等の種類が挙げられる。 Furthermore, the risk level of the target object may be calculated from the type of target object detected by the object detection sensor 10, the position of the target object, or the speed of the target object, and the display mode may be changed according to the calculated risk level. Specifically, a high risk object may be displayed in red, a medium risk object in yellow, and a low risk object in a blue graphic or the like. Here, examples of the type of the object include a type such as a pedestrian or a vehicle, an adult or a child.
　また、上記実施形態では、対象物の位置情報を物体検出センサ１０が直接検出することによって対象物の位置情報を取得したが、物体検出センサ１０等によって検出された情報から位置情報を算出することによって位置情報を取得してもよい。 In the above embodiment, the position information of the object is acquired by the object detection sensor 10 directly detecting the position information of the object. However, the position information is calculated from the information detected by the object detection sensor 10 or the like. The position information may be acquired by.
