  The obstacle sensor OS is a sensor that acquires the position and size of an obstacle present around the automobile. As the obstacle sensor OS, for example, a LiDAR (Light Detection and Ranging), a millimeter wave radar, a stereo camera, or the like can be employed.

  The location information acquisition unit PI is a device that acquires location information of the automobile. As the position information acquisition unit PI, for example, a GPS (Global Positioning System) can be used. The display control device 10 receives position data from the position information acquisition unit PI.

  The display unit 21 is an interface unit connected to the display device DS that displays an image. As the display device DS, for example, a head-up display that displays an image on the windshield of an automobile using the projection device PJ, a liquid crystal monitor, or the like can be employed. In this embodiment, an example in which a head-up display is employed will be described. In the case where a liquid crystal monitor is employed as the display device DS, an image captured by a camera (not shown) may be displayed on the display device DS as a background image.

  The output unit 22 is an interface unit connected to the speaker SP. The display control device 10 can output sound from the speaker SP.

  The storage device 23 includes, for example, a hard disk device, an SSD (Solid State Drive), a flash memory, or the like. The storage device 23 stores various programs such as BIOS (Basic Input Output System) and software. Further, the storage device 23 includes an obstacle instruction image indicating the width of an obstacle perpendicular to the path of the obstacle present on the course of the automobile, and the width of the automobile perpendicular to the course of the automobile. In other words, it is possible to store information for generating a vehicle width instruction image indicating the vehicle width and a wheel width instruction image indicating the width of the wheel of the automobile on the course of the automobile.

  Specifically, the storage device 23 includes a map DB (Data Base) storing map information, vehicle information including information on the vehicle such as the vehicle width, minimum ground clearance, and minimum wheel distance in the vehicle width direction. The vehicle route information can be stored. The map information includes road shape information such as road width, number of traffic zones, and undulations.

  The control unit 24 is realized by a computer having a CPU (Central Processing Unit) 24a as an arithmetic processing device, a ROM (Read Only Memory) 24b as a main storage device, and a RAM (Random Access Memory) 24c. The CPU 24a reads out a program corresponding to the processing content from the ROM 24b or the storage device 23, expands it in the RAM 24c, and realizes various functions in cooperation with the expanded program.

  Each of the input unit 20, the display unit 21, the output unit 22, the storage device 23, the control unit 24, and the position information acquisition unit PI is connected to each other via a system bus 25.

  The control unit 24 can acquire the height of the obstacle on the course of the automobile based on each data received via the input unit 20.

  Based on the respective data received via the input unit 20, the position information acquired from the position information acquisition unit PI, and each data stored in the storage device 23, the control unit 24 It is possible to generate a vehicle width instruction image and a wheel width instruction image.

  The control unit 24 can determine whether the automobile is in contact with an obstacle. For example, the control unit 24 can determine whether or not the automobile is in contact with the obstacle based on the obstacle instruction image and the vehicle width instruction image. Further, it is possible to determine whether or not the automobile is in contact with the obstacle based on the obstacle sensor OS. Furthermore, it is also possible to determine whether the obstacle can be an obstacle to the progress of the automobile based on the height of the obstacle. In addition, you may determine whether it may become the obstruction | occlusion of advancing of a motor vehicle based on whether a motor vehicle may contact an obstruction.

  Based on each data stored in the storage device 23, the control unit 24 can acquire information on a predicted route of the automobile, that is, route information.

  FIG. 2 shows an example in which a head-up display is adopted as the display device DS. As shown in FIG. 2, the head-up display includes a projection device PJ that emits light and a reflecting mirror RF that reflects the light emitted from the projection device PJ. Projector PJ and reflector RF are stored in the dashboard DB of the automobile.

  The light LT emitted from the projection device PJ is reflected by the reflector RF toward the windshield FG of the automobile. The light LT reflected by the reflecting mirror RF is irradiated on the windshield FG of the automobile through the opening window OP of the dashboard DB. Therefore, the driver DV sitting in the driver's seat of the car can recognize the information by looking at the images and videos displayed on the windshield FG.

  FIG. 3 shows a processing flow of the control unit 24. As shown in FIG. 3, the control unit 24 determines whether an obstacle is detected based on the data acquired from the obstacle sensor OS (step S11).

  If it is determined in step S11 that an obstacle has been detected (step S11Y), the control unit 24 generates an obstacle instruction image and a vehicle width instruction image (step S12). Here, the obstacle instruction image is an image showing the width of the obstacle in the vertical direction with respect to the course of the automobile and extending along the course of the automobile. The vehicle width instruction image is an image that shows the width of the automobile on the course of the automobile and extends along the course of the automobile.

  The control unit 24 causes the display device DS to display the vehicle width instruction image generated in step S12 (step S13). The control unit 24 determines whether the obstacle instruction image and the vehicle width instruction image overlap (step S14). In other words, the control unit 24 determines whether or not at least a part of the obstacle instruction image is included in the display position of the vehicle width instruction image. That is, in step S14, it is determined whether or not the automobile is in contact with an obstacle.

  If it is determined in step S14 that the obstacle instruction image and the vehicle width instruction image overlap (step S14Y), the control unit 24 generates the obstacle instruction image in the first mode and displays it on the display device DS. (Step S15), a warning sound is output from the speaker SP (Step S16).

  When it is determined in step S14 that the obstacle instruction image and the vehicle width instruction image do not overlap (N in step S14), the control unit 24 generates the obstacle instruction image in the second mode and displays the display device DS. (Step S17).

  In step S13, when it is judged that the control part 24 does not detect an obstruction (step S11: N), a process is complete | finished.

  FIG. 4A shows a vehicle width instruction image displayed on the display device DS in step S13 of FIG. In FIG. 4A, the mode on the course of the automobile viewed from the interior side of the automobile is shown. An obstacle OB exists on the left side of the road RD in the course of the automobile.

  On the windshield FG, a vehicle width instruction image CI indicated by an alternate long and short dash line in the drawing is displayed superimposed on the road RD. Specifically, the vehicle width instruction image CI has a strip shape extending from the automobile along the shape of the road RD, that is, along the course of the automobile. Therefore, the vehicle width instruction image CI indicates the width of the automobile on the course of the automobile and extends along the course of the automobile, and thus indicates the occupied width of the road RD of the automobile.

  FIG. 4B shows a first mode of the obstacle instruction image displayed on the display device DS in step S15 of FIG.

  On the windshield FG, an obstacle instruction image OI indicated by a dotted line in the figure is displayed superimposed on the road RD.

  Specifically, the obstacle instruction image OI has a strip shape extending from the obstacle OB along the shape of the road RD, that is, along the course of the automobile. Accordingly, the obstacle instruction image OI indicates the width of the obstacle OB in the direction perpendicular to the course of the automobile and extends along the course of the automobile, and thus indicates the occupied width of the road RD of the obstacle OB. ing.

  In this figure, at least a part of the obstacle instruction image OI is included in the display position of the vehicle width instruction image CI. In other words, the obstacle instruction image OI is displayed overlapping the display position of the vehicle width instruction image CI. Therefore, if the automobile continues to travel along this path, it may come into contact with the obstacle OB. In this case, the obstacle instruction image OI may be displayed in red that is reminiscent of danger.

  The obstacle instruction image OI and the vehicle width instruction image CI are displayed in such a manner that they can be visually distinguished from each other. For example, the vehicle width instruction image CI is displayed in blue with respect to the obstacle instruction image OI displayed in red. The obstacle instruction image OI and the vehicle width instruction image CI are virtual images projected by the head-up display.

  Note that the obstacle instruction image OI and the vehicle width instruction image CI may be generated so as to be displayed with a margin more than the actual size. For example, the obstacle instruction image OI may be generated so as to be displayed 1 m longer than the width of the obstacle OB, and the vehicle width instruction image CI may be displayed 0.5 m longer than the width of the automobile. The obstacle instruction image OI and the vehicle width instruction image CI are displayed with a dimension width considering the perspective when displayed on the windshield FG.

  Further, the vehicle width instruction image CI may be shown along route information that is a predicted course of the automobile. For example, when the obstacle OB exists on one of the Y-shaped branch roads and the other of the branch roads is the predicted course, the control unit 24 determines whether or not the vehicle is in contact with the obstacle OB. The processing may be terminated without generating the obstacle instruction image OI.

  The display of the first mode such as the obstacle instruction image OI may be performed together with the additional information. Specifically, in the upper part of the left side of the windshield FG in the drawing, “additional obstacle to 70 m” is indicated as additional information indicating the distance to the obstacle OB. Therefore, the driver DV can visually recognize the distance from the obstacle OB.

  The obstacle instruction image OI may blink according to the distance from the automobile to the obstacle OB. For example, the driver DV can recognize the distance to the obstacle OB by increasing the blinking speed or the like according to the distance from the automobile to the obstacle OB.

  FIG. 4C shows a second mode such as the obstacle instruction image OI displayed in step S17 of FIG. In this figure, a part of the obstacle instruction image OI is not included in the display position of the vehicle width instruction image CI. In other words, the obstacle instruction image OI is displayed without overlapping the display position of the vehicle width instruction image CI. Therefore, the automobile will not come into contact with the obstacle OB if it continues this course.

  Therefore, in the second display mode, since it is assumed that the automobile does not contact the obstacle OB, the obstacle instruction image OI may be displayed in green reminiscent of safety. That is, the obstacle instruction image OI having different aspects is generated in the first aspect and the second aspect.

  The obstacle instruction image OI only needs to be formed so as to extend along the course of the automobile, and may not be formed so as to extend from the obstacle OB. Similarly, the vehicle width instruction image CI may be formed so as to extend along the course of the automobile, and may not be formed so as to extend from the automobile. Further, the obstacle instruction image OI only needs to be able to visually recognize at least the width of the obstacle OB, and does not have to be a belt shape. Similarly, the vehicle width instruction image CI only needs to be able to visually recognize at least the vehicle width and does not have to be a belt shape.

  Further, in this embodiment, it is determined whether or not the automobile is in contact with the obstacle OB based on the obstacle instruction image OI and the vehicle width instruction image CI. However, it is not necessary to use the obstacle instruction image OI and the vehicle width instruction image CI for determining whether or not the automobile is in contact with the obstacle OB. For example, the size of the obstacle OB is acquired based on the data input from the obstacle line sensor OS, and the contact with the obstacle OB is determined from the vehicle width stored in the storage device 23. Good.

  Further, in step S16 of FIG. 3, the warning sound is output from the speaker SP. However, for example, a vibrator (not shown) may be provided in the driver's seat of the automobile to vibrate the vibrator. The vibration of the vibrator may be performed together with the output of the warning sound or may be performed instead of the output of the warning sound. In this way, it is possible to intuitively tell the driver DV the possibility that the automobile will come into contact with the obstacle OB.

  In addition, in step S13 of FIG. 3, it has been described that the process of displaying the vehicle width instruction image CI is performed. The process of step S13 may be performed anytime after step S12. For example, the process of step S13 may be displayed together with the obstacle instruction image OI in step S15.

  In the present embodiment, the control unit 24 generates the obstacle instruction image OI according to the determination in step S14. However, the control unit 24 changes the display mode by processing the obstacle instruction image OI generated in step S12, whereby the first aspect of the obstacle instruction image OI in step S15 and the obstacle instruction in step S17. You may make it display the 2nd aspect of the image OI.

  As described above, according to the display control apparatus 10 of the present embodiment, the relationship between the size of the obstacle OB and the position on the road RD, the size of the car, and the traveling position on the road is displayed in a superimposed manner on the front landscape. In order to avoid the obstacle OB, the driver DV can intuitively recognize how much the automobile should be moved in the vehicle width direction or not. As a result, the driver DV can avoid the obstacle OB with a degree of freedom of operation. For this reason, it is possible to display an appropriate driving assistance image for the operator.

  5 to 7 are flowcharts illustrating the processing flow of the display device according to the second embodiment. The display control apparatus 10 according to the second embodiment has the same configuration as that of the first embodiment, and the processing flow by the control unit 24 is different.

  As shown in FIG. 5, the control unit 24 determines whether or not the obstacle OB is detected based on the data acquired from the obstacle sensor OS (step S <b> 201).

  If it is determined in step S201 that the obstacle OB has been detected (step S201: Y), the control unit 24 determines that the height of the obstacle OB is a predetermined height determined in advance from the lowest ground height of the vehicle. It is determined whether or not the height is higher than the height obtained by subtracting (αcm) (hereinafter referred to as a reference height) (step S202).

  The reference height can be freely set, and may be, for example, only the minimum ground height of the automobile or only the specified height (α cm). Further, the minimum ground clearance may be the minimum ground clearance for each vehicle type or the legal minimum ground clearance.

  If it is determined in step S202 that the height of the obstacle OB is higher than the reference height (step S202: Y), the control unit 24 generates an obstacle instruction image OI and a wheel width instruction image WI. (Step S203). Here, the wheel width instruction image WI is an image that shows the width of the wheel of the automobile on the course of the automobile and extends along the course of the automobile. The wheel width instruction image WI is generated with reference to vehicle body information including, for example, the size of a tire mounted on a wheel of an automobile and the minimum distance between wheels in the vehicle width direction. A plurality of wheel width instruction images WI may be generated according to the type of moving body. For example, a pair of wheel width instruction images WI may be generated for an automobile, and a single wheel width instruction image WI may be generated for a two-wheeled vehicle such as a motorcycle.

  The control unit 24 causes the display device DS to display the wheel width instruction image WI generated in step S203 (step S204). The control unit 24 determines whether or not the obstacle instruction image OI and the wheel width instruction image WI overlap (Step S205). That is, the control unit 24 determines whether or not at least a part of the obstacle instruction image OI is included in the display position of the wheel width instruction image WI. By this determination, it is determined whether or not the automobile is in contact with the obstacle OB.

  When it is determined in step S205 that the obstacle instruction image OI and the wheel width instruction image WI overlap (step S205: Y), the control unit 24 generates the obstacle instruction image OI and the like in the third mode. It is displayed on the display device DS (step S206). The control unit 24 outputs a warning sound from the speaker SP (step S207).

  In step S201, when the control unit 24 determines that an obstacle is not detected (step S201: N), the process ends. In the determination of step S201, for example, even when an obstacle OB is detected, if an obstacle OB having a size that does not clearly obstruct the driving of the automobile such as a pebble is detected, the obstacle OB is detected. May be determined not to be detected.

  If it is determined in step S202 that the height of the obstacle OB is lower than the reference height (step S202: N), as shown in FIG. 6, the control unit 24 displays the obstacle instruction image OI, the vehicle A width instruction image CI is generated (step S208). The control unit 24 displays the vehicle width instruction image CI generated in step S208 on the display device DS (step S209). The control unit 24 determines whether or not the obstacle instruction image OI and the vehicle width instruction image CI overlap (Step S210).

  When it is determined in step S210 that the obstacle instruction image OI and the vehicle width instruction image CI overlap (step S210: Y), the control unit 24 generates the obstacle instruction image OI and the like in the fourth mode. It is displayed on the display device DS (step S211). The control unit 24 outputs a warning sound from the speaker SP (step S212).

  When it is determined in step S210 that the obstacle instruction image OI and the vehicle width instruction image CI do not overlap (step S210: N), the control unit 24 generates the obstacle instruction image OI and the like in the fifth mode. Then, it is displayed on the display device DS (step S213).

  When it is determined in step S205 that the obstacle instruction image OI and the wheel width instruction image WI do not overlap (step S205: N), as shown in FIG. It is determined whether or not the obstacle instruction image OI exists (step S214).

  When it is determined in step S214 that the obstacle instruction image OI exists inside the wheel width instruction image WI (step S214: Y), the obstacle instruction image OI is generated in the sixth mode and is displayed on the display device DS. It is displayed (step S215).

  If it is determined in step S217 that the obstacle instruction image OI does not exist inside the wheel width instruction image WI (step S214: N), the obstacle instruction image OI or the like is generated in the seventh mode and displayed. It is displayed on the DS (step S216).

  8A and 8B show the display mode of the obstacle instruction image OI when it is determined in step S202 that the height of the obstacle OB is higher than the reference height.

  FIG. 8A shows a fourth mode such as the obstacle instruction image OI displayed in step S211 of FIG. That is, the height of the obstacle OB is higher than the reference height, and it is determined that the obstacle instruction image OI and the vehicle width instruction image CI are overlapped.

  In this figure, the entire obstacle instruction image OI is included in the display position of the vehicle width instruction image CI. In other words, the entire obstacle instruction image OI is displayed so as to overlap the display position of the vehicle width instruction image CI. Therefore, if the car continues to take this path, it may come into contact with the obstacle OB. In this case, the obstacle instruction image OI may be displayed in red that is reminiscent of danger.

  FIG. 8B shows a fifth mode such as the obstacle instruction image OI displayed in step S213 of FIG. That is, it is a case where the height of the obstacle OB is higher than the reference height and it is determined that the obstacle instruction image OI and the vehicle width instruction image CI do not overlap.

  In this figure, a part of the obstacle instruction image OI is not included in the display position of the vehicle width instruction image CI. In other words, the obstacle instruction image OI is displayed without overlapping the display position of the vehicle width instruction image CI. Therefore, the automobile will not come into contact with the obstacle OB if it continues this course. In this case, the obstacle instruction image OI may be displayed in green reminiscent of safety.

  9A to 9C show display modes of the obstacle instruction image OI when it is determined in step S202 that the height of the obstacle OB is lower than the reference height.

  FIG. 9A shows a third mode such as the obstacle instruction image OI displayed in step S206 of FIG. That is, the height of the obstacle OB is lower than the reference height, and it is determined that the obstacle instruction image OI and the wheel width instruction image WI are overlapped.

  In this figure, a wheel width instruction image WI indicated by a one-dot chain line in the figure is displayed superimposed on the road RD on the windshield FG. Specifically, the wheel width instruction image WI has a belt-like shape extending from the automobile along the shape of the road RD, that is, along the course of the automobile. Accordingly, the wheel width instruction image WI indicates the width of the vehicle wheel on the route of the vehicle and extends along the route of the vehicle, and thus indicates the occupied width of the road RD of the wheel of the vehicle.

  In the drawing, a part of the obstacle instruction image OI is included in the display position of the wheel width instruction image WI. In other words, a part of the obstacle instruction image OI is displayed overlapping the display position of the wheel width instruction image WI. Therefore, if the car continues to take this path, it may come into contact with the obstacle OB. In other words, if the car continues to take this path, its wheels will ride on the obstacle OB. In this case, the obstacle instruction image OI may be displayed in red that is reminiscent of danger.

  Note that the wheel width instruction image WI only needs to be formed extending along the course of the automobile, and may not be formed extending from the automobile. Moreover, the wheel width instruction | indication image WI should just be able to recognize at least a wheel width visually, and does not need to be strip | belt shape.

  Further, the wheel width instruction image WI may be displayed with a margin more than the actual size. For example, the difference wheel width instruction image WI may be displayed 0.3 m longer than the width of the automobile. The wheel width instruction image WI is displayed with a dimensional width in consideration of perspective when displayed on the windshield FG.

  FIG. 9B shows a seventh mode such as the obstacle instruction image OI displayed in step S216 in FIG. This is a case where the height of the obstacle OB is lower than the reference height and it is determined that the obstacle instruction image OI and the wheel width instruction image WI do not overlap.

  In this figure, a part of the obstacle instruction image OI is not included in the display position of the wheel width instruction image WI. In other words, a part of the obstacle instruction image OI is displayed at the display position of the wheel width instruction image WI without overlapping. Therefore, the automobile will not come into contact with the obstacle OB if it continues this course. In this case, the obstacle instruction image OI may be displayed in green reminiscent of safety.

  FIG. 9C shows a sixth aspect such as the obstacle instruction image OI displayed in step S215 of FIG. This is a case where the height of the obstacle is lower than the reference height and it is determined that the obstacle instruction image OI and the wheel width instruction image WI overlap.

  In this figure, a part of the obstacle instruction image OI is not included in the display position of the wheel width instruction image WI. In other words, a part of the obstacle instruction image OI is displayed at the display position of the wheel width instruction image WI without overlapping.

  However, the obstacle instruction image OI is displayed between the pair of wheel width instruction images WI. Therefore, if the car continues to take this course, it passes over the obstacle OB without straddling the obstacle OB. In this case, the obstacle instruction image OI may be displayed in yellow that reminds attention.

  Note that the manner in which the obstacle instruction image OI is displayed may be changed according to the height of the obstacle OB. For example, as shown in FIGS. 8A and 8B, when an obstacle OB higher than the reference height exists on the road RD, the obstacle instruction image OI may be displayed in a solid color. On the other hand, as shown in FIGS. 9A to 9C, when an obstacle OB lower than the reference height exists on the road RD, the obstacle instruction image OI may be hatched. By dividing the display in this way, the driver DV can instantaneously determine whether or not it is an obstacle to the progress of the automobile. Similarly to the first embodiment, the obstacle instruction image OI may be blinked and displayed according to the distance between the vehicle and the obstacle OB.

  Further, when the vehicle cannot straddle the obstacle OB, that is, when an obstacle OB higher than the reference height exists on the road RD, additional information may be displayed together with the obstacle instruction image OI and the like.

  FIG. 10 shows a fourth mode such as the obstacle instruction image OI displayed in step S214 of FIG. That is, the height of the obstacle OB is higher than the reference height, and it is determined that the obstacle instruction image OI and the vehicle width instruction image CI are overlapped.

  In FIG. 10, on the upper part of the windshield FG, characters “impossible to straddle” are shown as additional information indicating that the automobile cannot straddle the obstacle OB. Therefore, the driver DV can instantly recognize that the obstacle OB cannot be visually straddled.

  Note that the processing for displaying the wheel width instruction image WI has been described in step S204 of FIG. The process of step S204 may be performed any time after step S203. For example, the process of step S204 may be displayed together with the obstacle instruction image OI in step S206.

  In the present embodiment, the control unit 24 generates the obstacle instruction image OI according to the determinations in step S205, step S210, and step S214. However, the control unit 24 displays the third mode to the seventh mode of the obstacle instruction image OI by processing the obstacle instruction image OI generated in step S203 or step S209 and changing the display mode. You may make it make it.

  As described above, according to the display control apparatus 10 of the present embodiment, the relationship between the size of the obstacle OB and the position on the road RD and the size of the car and the traveling position on the road RD is displayed in a superimposed manner on the front landscape. Thus, in order to avoid or straddle the obstacle OB, the driver DV can intuitively recognize how much the automobile should be moved in the vehicle width direction or not.

  The configuration, routine, or the like of the display control device 10 in the above-described embodiment is merely an example, and can be appropriately selected or changed according to the application.
