Definitions
- the present invention relates to a vehicle periphery display device including an image acquisition unit that acquires a vehicle periphery image captured by an image capturing device provided in the vehicle, and a display device that is provided in a vehicle interior and displays the periphery image.
- Patent Document 1 discloses a technique for superimposing and displaying an index line indicating a predicted travel path to a parking target position based on a steering angle of a steering operation by a driver when the vehicle is parked. .
- the index lines are displayed in a plane on the periphery image of the vehicle having a three-dimensional depth.
- the index line should lie with respect to the road plane reflected in the peripheral image, but it is difficult to recognize the positional relationship between the peripheral image and the index line.
- it is difficult to intuitively recognize the index line for example, it is difficult to distinguish between the line drawn on the road and the index line.
- the present invention has been made in view of the above problems, and an object thereof is to provide a peripheral display device that can easily recognize an index line.
- a first characteristic configuration of the present invention is an image acquisition unit that acquires a surrounding image of a vehicle photographed by a photographing device provided in the vehicle, a display device that is provided in a vehicle interior and displays the surrounding image, and a driver An index line output unit for displaying an index line serving as an index of the driver in a superimposed manner on the peripheral image with at least one of a shadow part and a side part adjacent to the index line at the time of driving operation It is in the point.
- the shadow portion when the shadow portion is provided, it is possible to generate a visual effect such that the index line is lifted with respect to the surrounding image of the vehicle having a three-dimensional depth by the shadow portion. That is, it is possible to produce a visual effect as if the occupant sees the index line actually arranged on the road surface or the like that is captured in the surrounding image from the driver's seat. As a result, the driver can reliably grasp the index line, and can appropriately present the index line to the driver.
- the index line superimposed on the peripheral image is displayed three-dimensionally by the side surface portion, and therefore the index line is also three-dimensional with respect to the peripheral image of the vehicle having a three-dimensional depth. It is easy to recognize the positional relationship between the peripheral image and the index line. Further, for a driver with color blindness, since the index line is displayed with a side portion, the color area of the index line increases, and the index line is easily recognized. On the other hand, for the driver who does not have color blindness, the thickness of the line is not emphasized by displaying the index line in three dimensions. As a result, the occupant can clearly recognize the positional relationship between the peripheral image and the index line.
- the index line is expressed more three-dimensionally, and the positional relationship between the peripheral image and the index line can be easily recognized.
- the second characteristic configuration of the present invention is that the index line output unit displays the shadow portion adjacent to the side surface portion.
- the shadow portion is displayed adjacent to the side surface portion, so that the display on the display device is orderly compared to the case where the side surface portion and the shadow portion are separated from each other, and the peripheral image and the index line are displayed. It becomes easy to recognize the positional relationship with.
- the third characteristic configuration of the present invention is that the index line output unit displays the index line with the side surface portion on the side close to the imaging device.
- This configuration makes it possible to produce a visual effect as if the occupant sees a three-dimensional index line that is actually placed on the road surface or the like shown in the surrounding image from the driver's seat. As a result, the occupant can more clearly recognize the positional relationship between the peripheral image and the index line. Further, the peripheral image and the index line can be more clearly distinguished.
- a fourth characteristic configuration of the present invention is that the indicator line output unit displays the indicator line with the shadow portion on the side close to the photographing apparatus.
- This configuration creates a visual effect as if the index lines were raised relative to the surrounding images, as if the occupants looked at the index lines that were actually placed on the road surface, etc., that were captured in the surrounding images from the driver's seat. Effects can be produced.
- the fifth characteristic configuration of the present invention is that the index line is a broken line.
- a sixth characteristic configuration of the present invention is that the index line is drawn by disposing an index having an arbitrary shape intermittently.
- a line originally included in a peripheral image such as a white line or a parking lot line on a road and an index line can be clearly distinguished.
- the index line output unit has a width of the index line and a width of the index line among the width of the side surface part and the width of the shadow part, The point is that the smaller the distance from the photographing apparatus, the narrower the display.
- This configuration allows the index line to have a sense of perspective and allows the occupant to more reliably grasp the positional relationship of the index line in the surrounding image.
- the eighth characteristic configuration of the present invention is that the index line is a parking frame line indicating a parking space.
- This configuration makes it easy to recognize the parking space on the display device screen and further reduces the burden of the occupant's parking operation during parking.
- the ninth characteristic configuration of the present invention is that the index line is a predicted trajectory line extending in the traveling direction of the vehicle and indicating a predicted trajectory of the vehicle movement according to the steering angle.
- This configuration makes it easy to recognize the predicted trajectory line on the display device screen.
- a tenth characteristic configuration of the present invention is that the index line is an extension line of a vehicle width extending in a traveling direction of the vehicle.
- the vehicle width here is the maximum width in the left-right direction of the vehicle. However, it may be set wider than the actual maximum width in consideration of safety.

Abstract
Description
図1及び図2はこの駐車支援装置を備えた車両30の基本構成を示したものである。運転席に備えられたステアリング24は、パワーステアリングユニット33と連動し、回転操作力を前輪28fに伝えて車両30の操舵を行う。前輪28fは本発明の操舵輪に相当する。車体前部にはエンジン32と、このエンジン32からの動力を変速して前輪28fや後輪28rに伝えるトルクコンバータやCVT等を有する変速機構34とが配置されている。車両30の駆動方式(前輪駆動、後輪駆動、四輪駆動)に応じて、前輪28f及び後輪28rの双方もしくは何れかに動力が伝達される。運転席の近傍には走行速度を制御するアクセル操作手段としてのアクセルペダル26と、前輪28f及び後輪28rのブレーキ装置31を介して前輪28f及び後輪28rに制動力を作用させるブレーキペダル27とが並列配置されている。
(1)第一実施形態では、設定された駐車目標位置に自動操舵により、車両30を誘導する例を示したが、これに限られるものではない。例えば、図10に示すように、周辺画像に指標線として車両の予想進路線を重畳表示して、この進路予想線に基づいて、運転者がステアリング操作等を行って駐車をするようにしてもよい。
