Description

  The present invention relates to a display device for a vehicle.

  2. Description of the Related Art In recent years, a technique for displaying side and rear images of a vehicle acquired from cameras provided on the left and right sides of the vehicle on a display in a vehicle compartment is known. In such a vehicle display device, there is a demand for a display method that allows the driver to recognize information intuitively and easily, equivalent to or more than when viewing the side mirror. In response to this problem, a vehicle display device has been proposed that is devised so that the driver can easily recognize which position around the vehicle the captured image represents (see Patent Document 1). Specifically, in the vehicle display device described in Patent Document 1, the ratio of the distance between the left and right displays installed on the instrument panel in the passenger compartment and the driver's seat is provided on the left and right sides of the vehicle. It is set to the same ratio as the distance between the left and right cameras and the driver's seat. By doing so, the driver can intuitively recognize which of the left and right displays is displaying the left and right images.

  However, in the configuration described in Patent Document 1 described above, an image corresponding to the side mirror display is displayed in the passenger compartment. For example, an image corresponding to the side mirror display such as a part ahead of the driver on the side of the vehicle is used. An area that is not displayed occurs, and the area can be a blind spot of the driver. Moreover, since the display is installed in the instrument panel, there is a concern that the driver's attention to the front during driving may be hindered.

  An object of the present invention is to provide a display device for a vehicle that reduces the blind spot of the driver and hardly disturbs the driver's attention during driving.

  One aspect of the present invention is a vehicle display device mounted on a vehicle, and includes a camera, a display, and a control unit. The camera is installed on at least one of the left and right sides of the vehicle, and the blind spot of the driver ahead of the driver on the side of the vehicle and the blind spot of the driver behind the driver on the side of the vehicle. The range including both is imaged. The display is installed at least on the side surface on the side where the camera is installed in the left and right sides of the vehicle interior of the vehicle. The control unit acquires a captured image from the camera and displays the captured image on a display.

  According to such a configuration, the driver's blind spot is reduced by displaying captured images including blind spots ahead and behind the driver on the display in the vehicle interior, and the display is installed on the side surface of the vehicle interior. Thus, the driver's attention during driving can be made difficult to disturb.

  As shown in FIG. 2, the right camera 1 is arranged in front of the driver's seat of the vehicle 100, and in the first embodiment, at a position where a general right side mirror is installed in the vehicle, instead of the side mirror. Is done. The right camera 1 images from the right front side of the vehicle 100 to the right rear side, in the first embodiment, an imaging region in a range R1 having a field angle of 180 °. Further, the right camera 1 is disposed slightly inside the right end of the vehicle 100 (in other words, so as not to protrude from the vehicle body of the vehicle 100). Thus, a part of the vehicle body of the vehicle 100 is included in the imaging region. Further, the range R1 includes a blind spot area RB1 that is a blind spot on the right front side of the driver (an area outside the range visible to the driver) generated by an A pillar (front pillar) on the right side of the vehicle 100 and a right side of the vehicle 100. A blind spot area RB2 which is a blind spot on the right rear side of the driver generated by the B pillar (center pillar) is included.

  Similar to the right camera 1, the left camera 2 is disposed at a position slightly inside the left side end of the vehicle 100 at a position where a general left side mirror is installed in the vehicle. The left camera 2 captures an imaging region in a range L1 that is an angle of view of 180 ° from the left front side of the vehicle 100 to the left rear side. The range L1 includes a blind spot area LB1 that is a blind spot in front of a part of the vehicle body of the vehicle 100, a left-hand side A pillar of the vehicle 100, and a left-hand side of the driver. A blind spot area LB2 which is a rear blind spot is included.

  Note that the right camera 1 and the left camera 2 are configured by arranging two image sensors that capture a 90 ° range side by side along the front-rear direction of the left and right sides of the vehicle 100.

  The ECU 3 includes a well-known CPU, ROM, RAM, in-vehicle network controller, and the like (not shown). ECU3 acquires the picked-up image imaged with the right camera 1 and the left camera 2, and performs the display process mentioned later. In the case of the first embodiment, the control of the vehicular display device 10 is executed by the ECU 3 used only for the control of the vehicular display device 10, but the control method is not limited to this, for example, other functions The ECU that controls the vehicle may be shared with the vehicle display device 10.

  The right display 41 and the left display 51 are substantially rectangular organic EL displays having long sides along the front-rear direction of the vehicle 100. As shown in FIG. 3, the right display 41 is disposed on the right side surface of the vehicle interior of the vehicle 100, that is, on the upper part of the door trim of the right front door 102 in the first embodiment. Similar to the right display 41, the left display 51 is disposed on the left side surface of the vehicle 100 with respect to the driver's seat 101 in the vehicle interior of the vehicle 100, in the first embodiment, on the upper part of the door trim of the left front door. The right display 41 displays a display image obtained by converting the captured image indicating the range R1 (the range of 180 ° on the right side of the vehicle 100), and the left display 51 displays the range L1 (the range of 180 ° on the left side of the vehicle 100). A display image obtained by converting the captured image indicating () is displayed. That is, the right display 41 and the left display 51 serve as electronic side mirrors that expand the field of view to a range of 180 °.

[1-2. Action]
Next, a series of flow of display processing by the vehicle display device 10 will be described. The display process is started when the ignition of the vehicle 100 is turned on, and is ended after a predetermined time after the engine is turned off.

  First, the ECU 3 acquires a captured image indicating an imaging region in the range R1 captured by the right camera 1. Next, the ECU 3 converts the acquired captured image into a display image P1 that is optimal for the driver to visually recognize, for example, as shown in FIG. Specifically, the ECU 3 acquires a captured image captured by the above-described two image sensors included in the right camera 1. Then, the ECU 3 performs a process of joining the captured images (captured images captured by the two image sensors) using a known image processing technique, and converts the captured image into a display image P1 indicating an imaging region in the range R1. Next, the ECU 3 displays the display image on the right display 41.

  The ECU 3 also performs the same process for the captured image acquired from the left camera 2 and converts it into a display image indicating an imaging region in the range L1, that is, the 180 ° range on the left side of the vehicle 100. The image is displayed on the left display 51.

  In this manner, the vehicle display device 10 displays the captured images acquired from the right camera 1 and the left camera 2 on the right display 41 and the left display 51 installed on the left and right sides of the vehicle 100 in the vehicle interior.

[1-3. effect]
(1a) The right display 41 and the left display 51 are respectively installed on the upper side surfaces of the door trims of the left and right front doors of the vehicle 100. The ECU 3 causes the right display 41 to display a display image including the blind spot area RB1 and the blind spot area RB2, and causes the left display 51 to display a display image including the blind spot area LB1 and the blind spot area LB2. According to such a configuration, the driver can recognize a display image including blind spots ahead and behind the driver. Therefore, according to the first embodiment, the driver's blind spot can be reduced. Further, the right display 41 and the left display 51 are installed on the side surfaces of the left and right door trims of the vehicle 100 that are outside the effective field of view of the driver. The term “outside the effective field of view” here refers to a range (such as a door trim of the front door) and a field of view within the driver's peripheral field of view when the driver is facing forward, for example, while the driver is driving. The range (such as the back seat) that does not fit in. Therefore, according to the first embodiment, it is possible to make it difficult to disturb the driver's attention to the front during driving. Furthermore, since the right display 41 and the left display 51 are installed directly beside the driver's seat 101, the driver looks directly to the left and right rear sides of the vehicle 100 and looks at the right and left rear sides rather than checking the periphery of the vehicle 100. The time for confirmation can be shortened.

  (1b) The right camera 1 and the left camera 2 are respectively disposed at positions where a general right side mirror and a left side mirror are installed in the vehicle. According to such a configuration, the positions of the right camera 1 and the right display 41 and the positions of the left camera 2 and the left display 51 are close to each other. Therefore, according to the first embodiment, the driver can easily understand the correspondence between the camera and the display intuitively.

  (1c) The right camera 1 is located slightly inside the right side edge of the vehicle 100, and the left camera 2 is located slightly inside the left side edge of the vehicle 100. According to such a configuration, a part of the vehicle body of the vehicle 100 is included in the imaging regions of the range R1 and the range L1, and the display image displayed on the right display 41 and the left display 51 also includes a part of the vehicle body. Is displayed. Therefore, according to the first embodiment, it becomes easier for the driver to intuitively grasp the sense of distance of the scenery around the vehicle 100 indicated by the display image.

  (1d) The right display 41 and the left display 51 are organic EL displays having a substantially rectangular shape in which the sides along the front-rear direction of the vehicle 100 are long sides. According to such a configuration, the right display 41 and the left display 51 are horizontally long and wide, and thus have a shape suitable for displaying a display image showing a 180 ° range. In addition, by adopting an organic EL display excellent in viewing angle characteristics for the right display 41 and the left display 51, even when the right display 41 and the left display 51 are viewed from other than the front, it is difficult for the visible color to change. Become. Therefore, according to the first embodiment, the driver can easily grasp the display images displayed on the right display 41 and the left display 51.

  (1e) The ECU 3 executes a process of connecting the captured images acquired from the two imaging elements included in the right camera 1 by a known image processing technique, and converts the captured image into a display image indicating the imaging region in the range R1. The ECU 3 also performs the same processing as the captured image acquired from the right camera 1 on the captured image acquired from the left camera 2, and converts it into a display image indicating the imaging region in the range L1. According to such a configuration, for example, the 180 ° range on the left and right sides of the vehicle 100 where the distortion of the captured image is less likely to occur than in the case of imaging a 180 ° range using one fisheye lens, respectively. The display image to be shown can be acquired. Therefore, according to the first embodiment, the driver can easily grasp the display images displayed on the right display 41 and the left display 51.

In the first embodiment, the blind spot area RB1 and the blind spot area LB1 correspond to an example of the driver's blind spot ahead of the driver on the side of the vehicle, and the blind spot area RB2 and the blind spot area LB2 are on the side of the vehicle. The ECU 3 corresponds to an example of a blind spot of a driver behind the driver, and the ECU 3 corresponds to an example of a control unit.
[2. Second Embodiment]
[2-1. Constitution]
The vehicle display device according to the second embodiment is different from the display processing according to the first embodiment in that a change in the magnification of the captured image is further added. In addition, the basic configuration is the same as that of the first embodiment, and the description of the same configuration as that of the first embodiment is omitted by using the same reference numerals.

[2-2. Action]
A series of flow of display processing by the vehicle display device of the second embodiment will be described.
First, the ECU 3 converts a captured image indicating the imaging range of the range R1 captured by the right camera 1 by the same processing as in the first embodiment. Next, the ECU 3 changes the magnification of the converted captured image (corresponding to the display image in the first embodiment) along the front-rear direction of the vehicle, and converts it into a display image.

  Here, regarding the setting of the enlargement ratio of the display image, the display image P2 shown in FIG. 5 and the enlargement ratio distribution shown in FIG. 6 are examples of the display image showing the right side of the vehicle 100 in the second embodiment. This will be described using the graph.

  The distribution of the enlargement ratio along the front-rear direction of the vehicle 100 in the display image P2 includes a front range A including an end portion that indicates the forefront of the vehicle 100, in other words, a leftmost end portion of the display image P2. Three of the rear range B including the end portion indicating the rearmost side of the vehicle 100, in other words, the rightmost end portion of the display image P2, and the central range C between the front range A and the rear range B. It is divided into. Specifically, the front range A is a range from the leftmost end of the display image P2 to a certain distance along the center direction of the display image P2. The rear range B is a range from the rightmost end of the display image P2 to a certain distance along the center direction of the display image P2. The center range C is all the ranges excluding the front range A and the rear range B, which correspond to the center portion of the display image P2.

  The ECU 3 changes the enlargement ratios of the front range A, the rear range B, and the center range C in the display image P2 based on the enlargement ratio distribution graph shown in FIG. The horizontal axis of the distribution of the enlargement ratio indicates a position along the horizontal direction of the display image P2 (the long side of the display image P2), and the vertical axis indicates the enlargement ratio of the display image P2. The distribution of the enlargement ratio is such that the position M, which is the middle position along the horizontal direction of the display image P2, is minimized, and the farther away from the position M, in other words, the leftmost end portion and the rightmost end of the display image P2. It gradually increases as it approaches the edge. In addition, at the boundary between the front range A and the central range C and the boundary between the rear range B and the central range C, the enlargement ratio is 100%. The enlargement ratio in the front range A and the rear range B gradually increases from 100% as it approaches the left and right ends from the boundary with the central range C. That is, in the front range A and the rear range B, so-called enlargement ratio is weighted. The enlargement ratio of the central range C gradually decreases from 100% as the position M approaches the boundary between the central range C and the front range A and the rear range B. That is, the display image P2 in the front range A and the rear range B is enlarged as it approaches the left and right ends of the display image P2. Then, the display image P2 in the central range C is reduced as it approaches the center of the display image P2. Further, the enlargement ratio is increased by weighting of the enlargement ratio in the front range A and the rear range B, and decreases as the position M approaches the center range C, so that the entire front range A, rear range B, and central range C are reduced. Is set so that the integral value of the enlargement ratio becomes 100%.

The ECU 3 displays the display image on the right display 41 after the change of the enlargement ratio, as in the first embodiment.
The ECU 3 also performs the same display process including the change of the magnification described above on the captured image acquired from the left camera 2 and displays the converted display image on the left display 51.

[2-3. effect]
(2a) The ECU 3 converts the converted captured image so that the enlargement ratio changes along the front-rear direction of the vehicle. The ECU 3 causes the right display 41 and the left display 51 to display a display image that is a captured image after conversion. The distribution of the enlargement ratio along the front-rear direction of the vehicle 100 in the display image includes a front range A including an end portion indicating the forefront of the vehicle 100, a rear range B including an end portion indicating the rearmost of the vehicle 100, and A central range C between the front range A and the rear range B is divided into three. The distribution of the enlargement ratio of the front range A and the rear range B gradually increases from 100% as it approaches the left and right ends from the boundary with the central range C. According to such a configuration, the front and rear of the vehicle 100 are enlarged and displayed on the right display 41 and the left display 51. That is, since the front and rear of the vehicle 100 imaged by the right camera 1 and the left camera 2 are far from the right camera 1 and the left camera 2, they are imaged smaller than the center side of the vehicle. Thus, by enlarging the front and rear of the vehicle 100 displayed in the display image, for example, the distant location of the vehicle 100 such as another vehicle existing behind the vehicle 100 approaching the vehicle 100 can be displayed. Compared with the case where the enlargement ratio is not changed, the display image is displayed larger. Therefore, according to the second embodiment, it becomes easier for the driver to grasp a change in the distance of the vehicle 100.

  (2b) The display images in the front range A and the rear range B are enlarged as they approach the left and right ends of the display image in the front-rear direction of the vehicle 100. According to such a configuration, the left and right end portions of the display image farthest from the right camera 1 and the left camera 2 are enlarged most. In other words, the portion of the display image that is originally the smallest displayed is displayed larger. Therefore, according to the second embodiment, it becomes easier for the driver to grasp a change in the distance of the vehicle 100.

(2c) The distribution of the enlargement ratio is increased by weighting of the enlargement ratio in the front range A and the rear range B, and decreases as the position M approaches the center range C, so that the front range A, the rear range B, and the central range are reduced. The integral value of the enlargement ratio is set to 100% for C as a whole. Therefore, according to the second embodiment, even if the front and rear of the vehicle 100 are enlarged and displayed, the display range of the display image along the front-rear direction of the vehicle 100 can be maintained.
[3. Third Embodiment]
[3-1. Constitution]
The vehicle display device according to the third embodiment has a shape in which the width along the vertical direction of the vehicle 100 gradually becomes narrower toward the front of the vehicle 100 instead of the substantially rectangular right display 41 and left display 51. The point which a certain right side display and left side display are used differs from the display apparatus 10 for vehicles of 1st Embodiment. In addition, the basic configuration is the same as that of the first embodiment, and the description of the same configuration as that of the first embodiment is omitted by using the same reference numerals.

  The display apparatus for vehicles of 3rd Embodiment is provided with the right side display 43 arrange | positioned at the right side of the vehicle 100 shown as an example in FIG. The right display 43 has a shape in which the width along the vertical direction of the vehicle 100 gradually narrows toward the front of the vehicle 100. Specifically, the shape of the right display 43 gradually decreases from the rear end of the right display 43 toward the front end of the right display 43. That is, the shape of the right display 43 is a substantially trapezoidal shape with the width 43A as the bottom and the width 43B as the top. The right display 43 is an organic EL display similar to the first embodiment, and is disposed on the upper part of the door trim of the right front door 102. As with the right display 43, the shape of the left display of the third embodiment is also a rough platform that gradually decreases from the rear end of the left display of the third embodiment toward the front end of the left display of the third embodiment. Shape. Further, the left display of the third embodiment is arranged on the upper part of the door trim of the left front door, like the left display 51 of the first embodiment.

[3-2. Action]
First, the ECU 3 executes a display process similar to that of the first embodiment for a captured image indicating the imaging range of the range R1 captured by the right camera 1. As shown in FIG. 7, the display image P <b> 3 converted by the display process is output by cutting a portion of the captured image displayed on the right display 43 so as to correspond to the shape of the right display 43. Specifically, the shape of the display image P <b> 3 is a substantially trapezoidal shape in which the width along the vertical direction of the vehicle 100 decreases as the vehicle 100 approaches from the rear to the front.

  The ECU 3 executes the same display process as the captured image acquired from the right camera 1 for the captured image acquired from the left camera 2. Similar to the display image P3 of the right display 43, the display image of the third embodiment has a substantially trapezoidal shape in which the width along the vertical direction of the vehicle 100 becomes narrower as it approaches the front from the rear of the vehicle 100. .

[3-3. effect]
(3a) The width along the vertical direction of the vehicle 100 of each of the right side display and the left side display of the third embodiment is gradually narrowed from the rear end to the front end. Therefore, according to the right side display and the left side display of the third embodiment, it becomes easier to intuitively grasp the traveling direction of the vehicle 100 as compared with a rectangular display. Moreover, since the shape of the right side display and the left side display of the third embodiment is substantially trapezoidal, a rectangle whose short side is the same length as the width of the rear end of the right side display and the left side display (the bottom of the trapezoid). The area of the display is reduced as compared to the display of the shape. Therefore, according to the third embodiment, for example, as the door trim of the front door approaches the front end from the rear end along the vehicle front-rear direction, the width along the vertical direction of the vehicle becomes narrower. Even if it is a shape, a highly visible right display and left display can be mounted.
