  By the way, when driving a vehicle, for example, in a situation where another vehicle to be overtaken is approaching rapidly from the left rear, a high degree of caution is required when changing lanes to the left or turning left. In such a case, the driver must first recognize that he should pay particular attention to the left rear and vehicle approach. That is, when the level of importance in any direction increases, the driver needs to quickly recognize the direction and the situation in that direction.

  However, the techniques described in Patent Documents 1 to 3 have a problem that it is difficult for the driver to quickly recognize the direction and the situation in which the level of importance has increased. The driver may not notice this even if there is a change in the captured image displayed on the rearview mirror or monitor because the ratio of the time of looking at the front of the vehicle and the instruments is high while driving. Because there is. Even if the driver notices, it takes some time before the driver shifts his / her line of sight to the captured image of the rearview mirror or monitor, and determines the direction and the situation in which the level of importance has increased from the content of the captured image. Because it takes.

  The present invention has been made in view of such points, and a vehicle driving support device, a vehicle driving support method, and a vehicle driving support program that enable a driver to quickly recognize the direction in which the level of importance has increased and the situation thereof. The purpose is to provide.

  The vehicle driving support device according to the present invention includes importance level determination means for determining the importance level from the viewpoint of safety with respect to a predetermined direction around the vehicle, and the front of the driver's seat when the level of the importance level increases. Display control means for moving the captured image in the predetermined direction from the end side corresponding to the predetermined direction to the center side.

  The vehicle driving support method of the present invention includes a step of determining an importance level from the viewpoint of safety with respect to a predetermined direction around the vehicle, a step of determining whether or not the level of the importance level has increased, When the level of importance rises, on the screen arranged in front of the driver's seat, moving the captured image in the predetermined direction from the end side corresponding to the predetermined direction to the center side; Have

  In the vehicle driving support program of the present invention, the computer mounted on the vehicle increases the level of importance and the processing for determining the importance from the viewpoint of safety with respect to a predetermined direction around the vehicle. And when the level of importance rises, on the screen arranged in front of the driver's seat, the captured image in the predetermined direction is viewed from the end side corresponding to the predetermined direction. A process of moving to the center side is executed.

  According to the present invention, since the captured image in the direction in which the level of importance has increased moves from the direction corresponding to the screen center side in front of the driver's seat, the driver can use the direction in which the level of importance has increased. And the situation can be recognized quickly.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram showing a configuration of a vehicle driving support system including a vehicle driving support device according to an embodiment of the present invention. This embodiment is an example in which the present invention is applied to a system that notifies the driver of the direction and state of sudden approach when another vehicle is approaching rapidly from the left rear and right rear of the vehicle. is there.

  In FIG. 1, the vehicle driving support system 100 includes a display 110, a left camera 120, a right camera 130, a left sensor 140, a right sensor 150, a vehicle information acquisition unit 160, an importance determination unit 170, and a display control unit 180. The vehicle driving support system 100 is mounted on a vehicle such as a passenger car. Hereinafter, a vehicle equipped with the vehicle driving support system 100 is simply referred to as a “vehicle”, and other vehicles are referred to as “other vehicles”.

  The display 110 is an image display device for displaying instruments such as a speed meter disposed in front of the driver's seat of the vehicle, and is a liquid crystal display, for example. Alternatively, it may be a screen screen on which an image is projected by a projector or the like. That is, the display 110 functions as an instrument display board (instrument panel) for driving the vehicle in a state where the instruments are displayed on the screen.

  The left camera 120 captures the left rear of the vehicle (hereinafter simply referred to as “left rear”) and outputs a video signal for displaying the left rear image in real time to the display control unit 180. The left camera 120 is a digital video camera including, for example, a CMOS (complementary metal oxide), and is installed on the upper part of the left side mirror of the vehicle.

  The right camera 130 captures the right rear of the vehicle (hereinafter simply referred to as “right rear”) and outputs a video signal for displaying the left rear image in real time to the display control unit 180. The right camera 130 is, for example, a digital video camera provided with a CMOS, and is installed on the right side mirror of the vehicle.

  The left sensor 140 includes a presence / absence of another vehicle in a predetermined left rear range (hereinafter referred to as “left rear range”) and a vehicle-to-vehicle distance (hereinafter simply referred to as “vehicle distance”) at predetermined time intervals. And the approach speed of the other vehicle with respect to the vehicle (hereinafter simply referred to as “approach speed”) are output to the importance determining section 170. The left sensor 140 is an obstacle sensor including, for example, a UWB (ultra wide band) radar, and is installed in the upper left part of the rear bumper of the vehicle.

  The right sensor 150 detects the presence / absence of another vehicle, the inter-vehicle distance, and the approach speed in a predetermined range at the right rear (hereinafter referred to as “right rear range”) at predetermined time intervals, and determines the importance of the detection result. To the unit 170. The right sensor 150 is an obstacle sensor including, for example, a UWB radar, and is installed in the upper right part of the rear bumper of the vehicle.

  The vehicle information acquisition unit 160 acquires information on the vehicle state such as the vehicle travel speed (hereinafter simply referred to as “travel speed”), the remaining fuel amount, and the coolant temperature at predetermined time intervals. The data is output to the display control unit 180. Further, the vehicle information acquisition unit 160 sequentially outputs the acquired traveling speed to the importance level determination unit 170.

  The importance determination unit 170 determines the importance of the left rear (hereinafter, “left importance” based on the detection results of the left sensor 140 and the right sensor 150 and the traveling speed acquired by the vehicle information acquisition unit 160 at predetermined time intervals. And the right rear importance (hereinafter referred to as “right importance”), and the acquired left importance and right importance are output to the display control unit 180. Specifically, the importance level determination unit 170 determines the left level of importance based on the presence or absence of a vehicle in the left rear range, the inter-vehicle distance in the left rear range, the approach speed in the left rear range, and the traveling speed. Further, the importance level determination unit 170 determines the right level of importance based on the presence / absence of a vehicle in the right rear range, the inter-vehicle distance in the right rear range, the approach speed in the right rear range, and the traveling speed. The method of determining the importance will be described later.

  The display control unit 180 generates an image of the instrument based on the information regarding the state of the vehicle, outputs the image data of the instrument panel to the display 110, and displays the instrument panel including the instrument on the display 110. . Hereinafter, the entire screen of the display 110 in a state where the instrument panel is displayed is referred to as a “panel screen”.

  In addition, the display control unit 180 uses the video signals from the left camera 120 and the right camera 130 in a state where the left rear image and the right rear image are horizontally inverted, that is, reflected by the side mirror. Display on the panel screen in a state similar to an image.

  However, when the left importance level rises, the display control unit 180 moves the left rear image from the left end side of the panel screen to the center side of the panel screen, and the right importance level rises. Then, the right rear image is moved from the right end side of the panel screen to the center portion side of the panel screen. The display and movement of the image is executed by, for example, the image movement processing unit 181 included in the display control unit 180. For example, the image movement processing unit 181 performs a process of superimposing the image data of the captured image on the image data of the panel screen. In this process, the display position of the specified captured image is moved and the size of the specified captured image is enlarged. And do.

  FIG. 2 is a diagram showing a state around the panel screen. Here, a state in which a left rear image is displayed on the panel screen is shown, and illustration of images other than the left rear image is omitted.

  As shown in FIG. 2, the panel screen 210 is disposed in the interior 220 of the vehicle where the instrument panel is disposed in a normal vehicle, that is, between the windshield 230 and the handle 240. The driver can see the central part of the panel screen 210 when viewed from the driver's seat through the opening of the handle 240. Therefore, the center portion of the panel screen 210 is the portion that is most easily visible to the driver.

  The left rear image 250 continuously moves from the left end side of the panel screen 210 toward the center of the panel screen 210 in the direction indicated by the arrow 260 when the level of importance on the left increases. For example, the moving distance is about 15 cm, and the moving time is about 1 second. The left rear image 250 disappears after being displayed for a few seconds at the center of the panel screen 210. For the driver, the left rear image 250 jumps in front of the eyes from the left side and is displayed for a while and then disappears.

  It is desirable that the left rear image 250 substantially coincides with the reflected image reflected on the left side mirror when viewed from the driver's seat. This is because the driver has a habit of checking the rear with the side mirror, and can more accurately grasp the direction in which the other vehicle is located, the inter-vehicle distance, and the approach speed. In order to make the captured image coincide with the reflected image of the side mirror, for example, the imaging range may be changed according to the direction of the side mirror, or manual correction of the imaging range may be accepted from the driver.

  A vehicle driving support system 100 shown in FIG. 1 is not shown, but includes a CPU (central processing unit), a storage medium such as a ROM (read only memory) storing a control program, and a working memory such as a RAM (random access memory). Etc. For example, the function of each unit is realized by the CPU executing the control program.

  Such a vehicle driving support system 100 displays, on the panel screen 210, the direction of the rapid approach on the panel screen 210, when the other vehicle suddenly approaches from the left rear. Can be slid in from the side corresponding to, that is, from the left side to the center. The same applies to a sudden approach of another vehicle from the right rear. In this case, the right rear image slides in from the right side. That is, the vehicle driving support system 100 recognizes the direction in which the danger is approaching from the movement of the photographed image when the danger is approaching in either the left rear or the right rear, and moves to the center portion of the panel screen 210. The content of the danger that is approaching can be recognized from the captured image.

  The human eye can sensitively sense the movement of the image and the direction of movement in the peripheral vision. Therefore, even if the driver is not gazing at the panel screen 210, the driver can quickly recognize the movement of the captured image and the direction of the movement as long as the panel screen 210 is in view. In addition, the feeling of moving the image from the left end side to the center side on the panel screen 210 can be easily replaced with the feeling of approaching from the left side of another vehicle. Similarly, the sense of movement of the image from the right end side to the center portion side on the panel screen 210 can be easily replaced with the sense of approach from the right side of the other vehicle. Therefore, the driver can intuitively determine whether the other vehicle is approaching rapidly from the left side or the right side. In addition, the human eye can quickly adjust the line of sight to what moves in the peripheral visual field. Further, the destination of the captured image is a position closer to the center of the panel screen 210. Therefore, the driver can quickly turn his / her line of sight on the captured image that has been slid to the center of the panel screen 210.

  For the size, moving distance, and moving time of the photographed image, for example, find the value that minimizes the time required to grasp the direction of movement and the contents of the photographed image, and apply the obtained values. What should I do?

  Hereinafter, the operation of the vehicle driving support system 100 having the above configuration will be described.

  FIG. 3 is a flowchart showing the operation of the vehicle driving support system 100. During the operation of the vehicle driving support system 100, output of video signals from the left camera 120 and right camera 130, output of detection results from the left sensor 140 and right sensor 150, and acquisition information from the vehicle information acquisition unit 160 are displayed. It is assumed that the output and the generation of the panel screen 210 by the display control unit 180 are continuously performed.

  First, in step S1100, the importance determining unit 170 determines the left importance and the right importance based on the detection results of the left sensor 140 and the right sensor 150 and the traveling speed acquired by the vehicle information acquisition unit 160. . Then, the importance level determination unit 170 outputs the determined left importance level and right importance level to the display control unit 180.

  The importance is determined by the following method, for example. The importance level determination unit 170 treats the importance levels by classifying them into two levels: a first level having a lower importance level and a second level having a higher importance level. The importance level determination unit 170 presets the upper limit value of the inter-vehicle distance, the lower limit value of the approach speed, and the lower limit value of the traveling speed as the second level condition. Then, the importance level determination unit 170 sets the second level when all the conditions of the second level are satisfied for each of the left rear and the right rear, and the first level otherwise. Determine the importance of that direction.

  For example, it is assumed that the condition of the second level is that the inter-vehicle distance is 20 m or less, the approach speed is 15 km / h or more, and the traveling speed is 60 km / h or more. In this case, when the inter-vehicle distance is 50 m, the approach speed is 15 km / h, and the traveling speed is 60 km / h, the condition for the inter-vehicle distance is not satisfied among the second level conditions. Therefore, the first level is determined. However, when the approach speed and the traveling speed remain constant and the inter-vehicle distance decreases as time passes and reaches 20 m, the second level condition is satisfied, and therefore the second level is determined.

  In step S1200, the display control unit 180 determines whether the left importance level has reached the second level. If the left importance level has reached the second level (S1200: YES), the display control unit 180 proceeds to step S1300, and if the left importance level has not reached the second level (S1200). : NO), the process proceeds to step S1400.

  Note that reaching the second level means shifting from the first level to the second level, that is, increasing the level of importance, and maintaining the second level. Shall be excluded. However, the display control unit 180 may proceed to step S1300 also when the state in which the left importance level is the second level continues for a predetermined time or longer.

  In step S <b> 1300, the display control unit 180 uses the video signal from the left camera 120 to move the left rear image from the left end side of the panel screen 210 to the center side of the panel screen 210. Let Specifically, the display control unit 180 first displays the left rear image at a first position on the left end side of the panel screen 210 with a small size. The display control unit 180 continuously moves the left rear image from the first position to the second position on the center side of the panel screen 210 while increasing the display size. Display for a few seconds and then disappear.

  In step S1500, the display control unit 180 determines whether to continue the process of sliding in the captured image according to the importance. When the above process is continued (S1500: YES), the display control unit 180 returns to step S1100, and when the above process is not continued (S1500: NO), the series of operations is terminated.

  In step 1400, the display control unit 180 determines whether the right importance level has shifted from the first level to the second level. When the right importance level shifts from the first level to the second level (S1400: YES), the display control unit 180 proceeds to step S1600, and the right importance level changes from the first level to the second level. If the level has not been shifted to (S1400: NO), the process proceeds to step S1500.

  Note that the display control unit 180 may also proceed to step S1600 when the state where the right importance level is the second level continues for a predetermined time or longer.

  In step S <b> 1600, the display control unit 180 uses the video signal from the right camera 130 to move the right rear image from the right end side of the panel screen 210 to the center side of the panel screen 210. Let Specifically, the display control unit 180 first displays the right rear image at a third position on the right end side of the panel screen 210 with a small size. Then, the display control unit 180 continuously moves the right rear image from the third position to the fourth position on the center side of the panel screen 210 while enlarging the display size, and at the fourth position. Display for a few seconds and then disappear. Then, the display control unit 180 proceeds to step S1500.

  By such an operation, when the other vehicle suddenly approaches from the left rear, the vehicle driving support system 100 slides the left rear image from the left to the center on the panel screen 210, and the other from the right rear. When the vehicle suddenly approaches, the right and left rear images can be slid on the panel screen 210 from the right side to the center.

  In addition, the vehicle driving support system 100 separates the processing at the left rear and the right rear so as to correspond to the situation where the other vehicle suddenly approaches from both the left rear and the right direction, and performs the separated processing in parallel. May be executed.

  4-7 is a figure which shows the change of the panel screen 210 when another vehicle approachs rapidly from the left rear.

  First, when both the left importance level and the right importance level are at the first level, that is, when no other vehicle is approaching from both the left rear side and the right rear side, as shown in FIG. Does not display a right rear image or a left rear image.

  When the importance level on the left reaches the second level, that is, when another vehicle suddenly approaches from the left rear, as shown in FIG. 5, the panel screen 210 is placed at the first position on the left end side. The left rear image 250 is displayed in a small size. Then, as shown in FIG. 6, the panel screen 210 moves the left rear image 250 to the center side while enlarging its size, and finally, as shown in FIG. 7, the left rear image 250 is moved. Is displayed large in the center.

  Thus, when another vehicle suddenly approaches from the left rear side, the panel screen 210 slides the left rear image 250 from the left end side to the center side while increasing its size. Since the size of the left rear image 250 gradually increases, it is possible to prevent the driver's attention from being excessively greater than when a large image suddenly appears. However, when the maximum size of the photographed image is originally small, a photograph or the like different from the photographed video may be slid so that the photographed image is displayed only in the center portion of the panel screen 210. Further, since the left rear image 250 is continuously displayed, it is possible to grasp the left rear state during the image moving operation.

  Note that when the importance level reaches the second level, the display control unit 180 does not move and enlarge the captured image all at once, but subdivides the importance level into three or more levels. The movement and expansion may be performed in stages.

  In this case, for example, when the importance level is the lowest, the display control unit 180 does not display the captured image as shown in FIG. 4 and when the importance level reaches the next level, FIG. As shown in the figure, the captured image is displayed small at the end. Then, when the importance reaches the next level, the display control unit 180 continuously moves and enlarges the captured image to the position and size shown in FIG. 6 and reaches the highest importance level. Sometimes, the captured image is further moved and enlarged to the position and maximum size of the center shown in FIG. As a result, the driver can recognize the subdivided level of importance and can easily recognize this as the level of importance increases. In addition, the rate of change of the importance level per time can be associated with the moving speed of the captured image, so that the driver can more easily detect the urgency.

  When the intermediate level continues for a predetermined time or when the level drops, the display control unit 180 causes the captured image to disappear, or sets a lower limit value for a new display time interval of the captured image. Also good. Thereby, the excessive display of information can be prevented.

  In addition, the left camera 120 and the right camera 130 are in the first level, that is, the images of the left camera 120 and the right camera 130 even when no other vehicle is approaching from the left rear or the right rear. May be displayed at both ends of the panel screen 210.

  FIG. 8 is a diagram illustrating a state of the panel screen 210 when a captured image is always displayed.

  As shown in FIG. 8, the panel screen 210 displays the left rear image 250 in a large size at the left end, and displays the right rear image 270 in a large size at the right end. As a result, the driver can use the left rear image 250 and the right rear image 270 as auxiliary images of both side mirrors, and can easily check the left and right rear of the vehicle. When another vehicle suddenly approaches from the left and right rear, the left rear image 250 and the right rear image 270 may be slid as they are, or the display positions of these images may be fixed, You may slide an image.

  As described above, according to the present embodiment, when the level of importance in a predetermined direction increases, the captured image in that direction moves from the corresponding direction to the center side on the instrument panel of the vehicle. Thus, the driver can quickly recognize the direction in which the level of importance has increased and the situation. As a result, the vehicle can be operated more safely.

  In the embodiment described above, the case where the left and right cameras are installed above the side mirrors has been described. However, the left and right cameras may be installed at other positions. However, especially in this case, the vehicle driving support device allows the driver to easily grasp the viewpoint of the camera so that the driver can roughly grasp the direction in which the vehicle is located, the inter-vehicle distance, and the approach speed. It is preferable that it is the structure which can do. For example, the left and right cameras rotate the optical axis at the time of startup or the like, and the display control unit 180 displays an image when the optical axis is rotating on the display 110. Thus, the driver can sensuously grasp the rotation center of the optical axis from the video as the viewpoint of the camera. Further, a part of the vehicle may be displayed on the captured image. Further, the display 110 may display an image in which a figure indicating the position of the camera and the shooting range is added to the icon of the vehicle body.

  Further, the optical axis direction of the camera may be variable, and the optical axis of the camera may be directed in the direction in which the vehicle approaching rapidly is located. In this case, it is desirable to set more movement directions of the captured image on the panel screen so that the difference in the approach direction can be recognized in finer sections.

  Moreover, although the case where the captured image is slid in only for the left rear and the right rear of the vehicle has been described, the captured image may be similarly slid in the other directions. For example, when shooting and determining the importance of the rear front of the vehicle and the importance level of the rear front increases, the captured image may be moved from the lower end side to the center side of the panel screen. Good.

  In addition, the display control unit changes at least one of the display position, display size, display range, transparency, and display presence / absence of the display of the instrument image according to the change in the display position of the captured image or the presence / absence of the display. You may do it. However, the display control unit changes the display state of the captured image and the display state of the image of the instrument within a range that does not disturb the necessary display state of the instrument.

  Further, the display control unit may highlight the captured image according to the level of importance. The highlighting includes, for example, coloring of the image portion of the other vehicle, the image portion of the traveling lane of the other vehicle, and an increase in the moving speed of the captured image. Further, the vehicle driving support device may also perform a warning by voice or vibration from the direction corresponding to the direction in which the level of importance increases. With these highlights and additional warnings, it is possible to more reliably and quickly recognize the direction and the situation in which the level of importance has increased.

  Various methods can be adopted as a method for determining the level of importance. For example, the level of importance may be determined based on the vehicle type, obstacle type, road condition, driver, content of driving operation, etc. of other vehicles. However, especially when determining the level of importance based on the vehicle type or the obstacle type, the vehicle type or the obstacle type is determined by a sensor that can detect these immediately, or by image analysis processing on the captured image. A device unit for determination is prepared.

  Further, whether to slide in the photographed image may be determined from the degree of necessity of attention based on a viewpoint other than the safety viewpoint. The object to be slid may be an image other than the captured image. For example, the vehicle driving support device may be configured to slide image information acquired from the car navigation system into the instrument panel in cooperation with the car navigation system. In this case, for example, when the car navigation system determines that there is a facility to which attention should be paid to the left hand in the traveling direction and has image information related to the facility, the vehicle driving support device uses the image information as follows: What is necessary is just to display on the left end side of a panel screen, and to move continuously to the center part of a panel screen. Accordingly, the driver can quickly recognize that a facility to be noted appears on the left hand and information related to the facility.

  In addition, a device that can be retrofitted to the vehicle may be employed as the camera and the sensor, and a control program for a general-purpose computer may be employed as the vehicle information acquisition unit, the importance level determination unit, and the display control unit. In this case, the vehicle driving support device according to the present invention can be easily mounted on a vehicle equipped with a display for an instrument panel and a general-purpose computer.

  The vehicle driving support device, the vehicle driving support method, and the vehicle driving support program according to the present invention are a vehicle driving support device and a vehicle driving support method that enable the driver to quickly recognize the direction and the situation in which the level of importance has increased. It is also useful as a vehicle driving support program.
