The display control device 1 of FIG. 1 controls a virtual display unit 21 which is a display unit. The virtual display unit 21 can display one or more display objects that are viewed from the driver's seat of the host vehicle superimposed on a scene outside the host vehicle. That is, the virtual display unit 21 can display a virtual display object that can be seen by the driver of the host vehicle as if existing in the three-dimensional space of the real world. For example, a HUD that displays a virtual image or holography, an autostereoscopic display device, or the like is applied to such a virtual display unit 21.

  The display control device 1 of FIG. 1 includes an information acquisition unit 11 and a control unit 12.

  The information acquisition unit 11 acquires information that can be used to move the display object. The display object includes a first display object indicating a pole for the driver to visually recognize the positional relationship between the vehicle and the obstacle, that is, a pole corresponding to a corner pole. In the following description, except for the fourth embodiment, the first display object is referred to as a “pole object”. As information that can be used to move the pole object, as described in the second and subsequent embodiments, a user operation or the like for moving the pole object is used.

Move it. The predetermined range includes at least one of a range overlapping with the front end of the body of the host vehicle and a range around the front end of the body of the host vehicle. For example, a front bumper of the host vehicle, or a fender of the host vehicle and a front bumper are applied to the front end of the body of the host vehicle.

<Summary of Embodiment 1>
According to the display control device 1 according to the first embodiment as described above, it is possible to virtually move the corner pole. Therefore, the deterioration of the cost and appearance of hardware can be suppressed.

Second Embodiment
FIG. 2 is a block diagram showing a configuration of a display control device 1 according to Embodiment 2 of the present invention. Hereinafter, among the components described in the second embodiment, the same or similar components as or to the components described above are designated by the same reference numerals, and different components will be mainly described.

  Before describing the internal configuration of the display control device 1, the operation input unit 22 will be described. The virtual display unit 21 is the same as that of the first embodiment.

  The operation input unit 22 receives from the driver various operations such as an operation for moving the pole object, and outputs an operation signal indicating the received operation to the display control device 1. In the second embodiment, the operation input unit 22 will be described below as a touch panel. However, the operation input unit 22 includes, for example, a switch for receiving a driver's pressing operation, a voice operation input device for receiving a driver's voice operation, and a gesture operation input device comprising a camera for receiving a driver's gesture on a space as an operation. In addition, at least one of the gaze operation input device including a camera or the like that receives the movement of the driver's gaze as an operation may be used. In addition, any device may be used as long as the operation device can input the driver's intention. Some of these will be described in detail in the variations described below.

  Next, the internal configuration of the display control device 1 of FIG. 2 will be described. The display control device 1 includes an operation signal input unit 11a, a virtual display object generation unit 12a, a display position control unit 12b, and a display control unit 12c. The operation signal input unit 11a is included in the concept of the information acquisition unit 11 of FIG. 1 of the first embodiment. The virtual display object generation unit 12a, the display position control unit 12b, and the display control unit 12c are included in the concept of the control unit 12 in FIG. 1 of the first embodiment, as indicated by the broken line in FIG.

  When the operation input unit 22 receives an operation, the operation signal input unit 11a acquires an operation signal indicating the operation from the operation input unit 22. Therefore, when the operation input unit 22 receives an operation to move the pole object, the operation signal input unit 11a acquires, from the operation input unit 22, the information on the operation to move the pole object. In the following description, an operation for moving a pole object is referred to as a "moving operation".

  The virtual display object generation unit 12a generates a display object to be displayed on the virtual display unit 21 based on the operation acquired by the operation signal input unit 11a. In the second embodiment, the virtual display object generation unit 12a generates a pole object based on the movement operation acquired by the operation signal input unit 11a. The virtual display object generation unit 12a may generate a pole object based on a signal indicating that the accessory power supply of the host vehicle is turned on.

  The display position control unit 12 b determines the display position of the display object generated by the virtual display object generation unit 12 a based on the operation acquired by the operation signal input unit 11 a. When the virtual display unit 21 is a HUD that displays a virtual image, the display position control unit 12b determines the position of the virtual image as the display position. Here, the position of the virtual image is a position in a three-dimensional coordinate space with a specific position of the vehicle (for example, a driver's seat or a windshield) as a reference such as an origin. When the three-dimensional coordinate space is a polar coordinate space, the position of the virtual image is defined by, for example, a virtual image direction which is a virtual image direction and a virtual image distance which is a distance to the virtual image. When the coordinate space is an orthogonal coordinate space, the position of the virtual image is defined by, for example, coordinates on three orthogonal coordinate axes defined in the longitudinal direction, the lateral direction, and the vertical direction of the vehicle.

  In the second embodiment, the display position control unit 12b determines the display position of the pole object at a position overlapping any of the fender of the host vehicle and the front bumper based on the movement operation acquired by the operation signal input unit 11a. .

  The display control unit 12c controls the virtual display unit 21 to display the display object generated by the virtual display object generation unit 12a at the display position determined by the display position control unit 12b. In the second embodiment, the display control unit 12c controls the virtual display unit 21 to display the pole object generated by the virtual display object generation unit 12a at the display position determined by the display position control unit 12b. Do.

<Operation>
FIG. 3 is a flowchart showing the operation of the display control device 1 according to the second embodiment.

  First, in step S1, the virtual display object generation unit 12a generates a pole object based on the operation or the like acquired by the operation signal input unit 11a. The display position control unit 12 b determines the display position of the pole object as the initial position. Thereby, the display control unit 12c controls the virtual display unit 21 to display the pole object at the initial position. In the second embodiment, it is assumed that the initial position is the position of the front end on the passenger's seat side in the body of the host vehicle, like the position of a general corner pole.

  FIG. 4 is a view showing a state in which the vehicle can be seen through the windshield 31 from the inside of the host vehicle when step S1 is performed. FIG. 4 shows the bonnet 32 and the rearview mirror 33 of the host vehicle, and the pole object 34 displayed at the same initial position as the position of the corner pole. The bonnet 32 may not be visible depending on the vehicle type of the host vehicle.

  In the following description, it is assumed that the host vehicle is a left-handed vehicle. Further, in the following description, FIG. 5 may be used instead of FIG. 4 which schematically shows a state in which the vehicle can be seen through the windshield 31 from the inside of the host vehicle. It is shown that the code | symbol of the own vehicle 2 is attached | subjected to the bonnet 32 by this schematic diagram.

  In step S2 of FIG. 3, the display position control unit 12b determines whether the operation signal input unit 11a has acquired a move operation. If it is determined that the move operation has been acquired, the process proceeds to step S3. If it is determined that the move operation has not been acquired, the process of step S2 is performed again.

  FIG. 6 is a diagram showing an example of an arrangement relationship between the host vehicle 2 and another vehicle 51a which is an obstacle. Note that FIG. 6 not only shows the pole object 34 displayed at the initial position 2a by the step S1, but also the positions 2b and 52 of the respective portions forming the shortest distance between the host vehicle 2 and the other vehicle 51a. Is also shown.

  In the arrangement relationship of FIG. 6, the driver who is trying to drive the own vehicle 2 near the other vehicle 51a determines the position 2b, 52 in order to determine whether the own vehicle 2 collides with the other vehicle 51a. It is thought that the distance between them is measured. At this time, if the pole object 34 is displayed not at the initial position 2a but at the position 2b, it can be expected to increase the determination of the collision. Therefore, in the case as shown in FIG. 6, the driver performs the moving operation in step S2 of FIG. 3, and the process proceeds to step S3.

  In step S3, the display position control unit 12b determines the display position of the pole object 34 based on the movement operation acquired by the operation signal input unit 11a. The display control unit 12 c controls the virtual display unit 21 to display the pole object 34 at the display position determined by the display position control unit 12 b. Thereby, the pole object 34 moves. Thereafter, the process returns to step S2.

  FIG. 7 is a view showing a state in which the vehicle can be seen through the windshield 31 from the inside of the host vehicle when steps S2 and S3 are performed. As shown in FIG. 7, the pole object 34 is moved from the initial position to a position intended by the driver by repeating step S2 and step S3. When the virtual display unit 21 is a HUD displaying a virtual image and the virtual image distance is defined with reference to the driver's seat, the pole object 34 moves from the driver's seat to the assistant's seat. As a result, the virtual image distance of the pole object 34 becomes longer.

  FIG. 8 is a diagram showing the pole object 34 moved from the initial position 2a to the position 2b in the arrangement relationship of FIG. In this case, the driver of the own vehicle 2 makes the own vehicle 2 travel so that the own vehicle 2 does not collide with the other vehicle 51 a while observing the distance between the positions 2 b and 52 using the pole object 34 as an index. It can be performed.

<Summary of Embodiment 2>
According to the display control device 1 according to the second embodiment as described above, the pole object 34 can be moved based on the operation of moving the pole object 34. Thus, the user can move the pole object 34 to the intended position.

  Further, in the second embodiment, since the initial position of the pole object 34 is the position of the front end of the body of the host vehicle on the passenger seat side, the pole object 34 should be used in the same manner as the conventional corner pole. Can.

Each Modified Example of Second Embodiment
Next, each modification of the second embodiment will be described. Note that the display mode such as the color of the pole object 34 is changed depending on the modified example described below. Such a change in the display mode may be performed when the virtual display object generation unit 12a generates the pole object 34, or may be performed when the display control unit 12c controls the virtual display unit 21. . In the following description, in order to reduce redundant description, when operation is performed by at least one of the virtual display object generation unit 12a, the display position control unit 12b, and the display control unit 12c, control is performed instead of the description. It may be stated that the operation is performed by the unit 12.

<Modification 1 of Embodiment 2>
When the virtual display unit 21 is a HUD, the display control unit 12c according to the second embodiment described above assumes changing both the virtual image distance and the virtual image direction of the pole object 34 based on the moving operation. The However, the present invention is not limited to this, and the display control unit 12c may change the virtual image direction of the pole object 34 without changing the virtual image distance of the pole object 34 based on the moving operation. According to such a configuration, a HUD that does not change the virtual image distance can be used for the virtual display unit 21.

  In addition, since the eye position differs depending on the driver, calibration may be appropriately performed on the initial position of the pole object. The calibration may be performed automatically based on the detection result or estimation result of the position of the driver's eyes, or the driver operates the menu screen to manually set the pole object to the appropriate display position. May be implemented by

<Modification 2 of Embodiment 2>
Although not shown, it is assumed that the display control device 1 according to the present modification includes a vehicle information acquisition unit included in the concept of the information acquisition unit 11 of FIG. 1.

  FIG. 9 is a flowchart showing the operation of the display control device 1 according to the present modification. The operation in FIG. 9 is similar to that in which step S11 is added between step S1 and step S2 in FIG.

  After step S1, in step S11, the vehicle information acquisition unit acquires the speed of the host vehicle from an ECU (Electronic Control Unit) of the host vehicle or the like. The display position control unit 12b determines whether the speed of the host vehicle acquired by the vehicle information acquisition unit is smaller than a predetermined speed (for example, 10 km / hr). If it is determined that the speed of the host vehicle is lower than the predetermined speed, the process proceeds to step S2, and if it is determined that the speed of the host vehicle is equal to or higher than the predetermined speed, the process Return to S1.

  If it is determined in step S2 that the move operation has been acquired, the process proceeds to step S3, and if it is determined that the move operation is not acquired, the process returns to step S11. After the process of step S3 is performed, the process returns to step S11.

  According to the display control device 1 according to the present modification as described above, the position of the pole object 34 is fixed at the initial position when the speed of the host vehicle is equal to or higher than a predetermined speed. According to such a configuration, it is possible to suppress that the pole object 34 gets in the way of the driver's vision while the host vehicle is traveling.

  In addition, the above-mentioned vehicle information acquisition part may acquire the automatic driving information which shows whether automatic driving | running | working is performed by the own vehicle instead of the speed of the own vehicle from ECU etc. of the own vehicle. Then, in step S11 of FIG. 9, the display position control unit 12b determines whether or not the automatic driving information acquired by the vehicle information acquiring unit indicates that the automatic driving is performed by the own vehicle. It is also good. If the host vehicle does not indicate that automatic driving is being performed, the process proceeds to step S2, and if the host vehicle indicates that automatic driving is being performed, the process proceeds to step S1. An action may be taken to return to. The display position control unit 12 b configured as described above fixes the position of the pole object 34 at the initial position when the automatic driving information indicates that the automatic driving is performed in the own vehicle. According to such a configuration, as described above, it is possible to suppress that the pole object 34 gets in the way of the driver's vision during automatic driving of the host vehicle.

<Modification 3 of Embodiment 2>
Although not shown, it is assumed that the display control device 1 according to the present modification includes a peripheral brightness acquisition unit included in the concept of the information acquisition unit 11 of FIG. 1. The peripheral brightness acquisition unit acquires the brightness around the host vehicle acquired by the brightness sensor, or acquires an illumination signal when the illumination display is performed on the host vehicle.

  The control unit 12 controls the color and the brightness of the pole object 34 when the brightness around the host vehicle acquired by the peripheral brightness acquisition unit is equal to or less than the threshold or when the illumination signal is acquired by the peripheral brightness acquisition unit. Change to a color and brightness that is noticeable even in a dark environment. According to such a configuration, the pole object 34 can be easily viewed even in a dark environment. In the present specification, the color includes not only one color but also a color tone such as a pattern in which a plurality of colors are combined.

<Modification 4 of Embodiment 2>
Although Embodiment 2 demonstrated that the touch panel was used for the operation input part 22 of FIG. 2, it was not limited to this. For example, the operation input unit 22 may use a gesture operation input device that detects an indication direction pointed by the driver's finger. Then, when the pointing direction is detected by the gesture operation input device, the display control device 1 may move the pole object 34 to a position on the pointing direction. Alternatively, after the display control device 1 determines that the pole object 34 exists in the pointing direction detected by the gesture operation input device, another pointing direction is detected when the gesture operation input device detects another pointing direction. The pole object 34 may be moved to the upper position.

  Further, for example, a line-of-sight operation input device that detects the line-of-sight direction of the driver may be used for the operation input unit 22. Then, after the display control device 1 determines that the pole object 34 exists in the gaze direction detected by the gaze operation input device, when another gaze direction is detected by the gaze operation input device, the other gaze direction is detected. The pole object 34 may be moved to the upper position.

  Also, for example, both the gesture operation input device and the voice operation input device may be used for the operation input unit 22.

  FIG. 10 is a flowchart showing an operation of the display control device 1 according to the present modification when the gesture operation input device and the voice operation input device are used for the operation input unit 22. The operation in FIG. 10 is similar to that in which step S21 is added before step S1 in FIG. 3 and step S2 in FIG. 3 is replaced with steps S22 to 25.

  First, in step S21, the control unit 12 determines whether the operation input unit 22 and thus the operation signal input unit 11a have acquired a voice of a display command for displaying the pole object 34, for example, a voice of "corner pole display" Determine If it is determined that the voice of the display command has been acquired, the process proceeds to step S1, and if it is determined that the voice of the display command has not been acquired, the process of step S21 is performed again.

  Thereafter, in step S1, the control unit 12 controls the virtual display unit 21 to display the pole object 34 at the initial position.

  In step S22 after step S1, the control unit 12 causes the operation input unit 22 and thus the operation signal input unit 11a to generate an audio of an erase command for erasing the display of the pole object 34, for example, an audio of “corner pole erase”. It is judged whether or not it acquired. If it is determined that the voice of the delete command has been acquired, the process proceeds to step S23. If it is determined that the voice of the delete command has not been acquired, the process proceeds to step S24.

  At step S23, control unit 12 controls virtual display unit 21 to erase the display of pole object 34. Thereby, the pole object 34 is erased. Thereafter, the process returns to step S21.

  In step S24, the control unit 12 causes the operation input unit 22 and thus the operation signal input unit 11a to acquire the voice of the movement command for moving the pole object 34, for example, the voice of "corner pole movement", and the pole It is determined whether a gesture operation pointing to the object 34 has been acquired. That is, as shown in FIG. 11, the control unit 12 determines whether the driver has uttered the movement command while pointing in the same direction as the pole object 34. If it is determined that the voice of the movement command and the gesture operation pointing to the designated direction have been acquired, the process proceeds to step S25. If not, the process returns to step S22. When the process proceeds to step S25, the control unit 12 may blink the tip of the pole object 34.

  In step S25, the control unit 12 causes the operation input unit 22 and thus the operation signal input unit 11a to acquire an audio of a determination command for determining the display position of the pole object 34, for example, an audio of “corner pole determination”. In addition, it is determined whether a gesture operation pointing to a pointing direction different from that of the pole object 34 has been acquired. That is, as shown in FIG. 12, the control unit 12 determines whether the driver has uttered the determination command while pointing to a pointing direction different from that of the pole object 34. If it is determined that the voice of the determination command and the gesture operation pointing to the other indicated direction have been acquired, the process proceeds to step S3, and if not, the process of step S25 is performed again. If it is determined that the voice of the determination command and the gesture operation pointing to another designated direction have not been acquired even if the process of step S25 is performed a certain number of times, the process may return to step S22.

  In step S3, the control unit 12 controls the virtual display unit 21 so as to display the pole object 34 in the above-mentioned another instruction direction. Thereafter, the process returns to step S22.

  In the above description, the configuration using both the gesture operation input device and the voice operation input device in the operation input unit 22 has been described. However, the present invention is not limited to this. For example, the operation similar to that described above can be realized even if both the sight-line operation input device and the voice operation input device are used for the operation input unit 22.

  In addition, only the gesture operation input device is used in the operation input unit 22, and instead of acquiring various commands such as display commands from the voice, a specific gesture operation such as a swing of a driver's finger, etc. The same operation as the above can be realized even in the configuration for acquiring.

FIG. 13 is a block diagram showing a configuration of a display control device 1 according to Embodiment 3 of the present invention. Hereinafter, among the components described in the third embodiment, the same or similar components as or to the components described above are designated by the same reference numerals, and different components will be mainly described.

  Before describing the internal configuration of the display control device 1, the periphery detection unit 23 will be described. The virtual display unit 21 and the operation input unit 22 are the same as in the second embodiment.

  The periphery detection unit 23 acquires information on obstacles such as other vehicles around the host vehicle. This information includes the relative position of the obstacle and the vehicle. For example, at least one of an ultrasonic sensor, an image recognition device, a laser radar, a millimeter wave radar, an acoustic recognition device, and a night vision camera may be used for the periphery detection unit 23 or any other than the above. A sensing device may be used.

The external information input unit 11 b and the relative position acquisition unit 11 c are included in the concept of the information acquisition unit 11 in FIG. 1.

  The external information input unit 11 b acquires information on an obstacle around the host vehicle from the surrounding area detection unit 23. This information includes information on the relative position of the obstacle and the vehicle.

  The relative position acquisition unit 11c stores in advance the internal position of the vehicle, which is any position in the vehicle required to obtain the relative position acquired by the external information input unit 11b. The relative position acquisition unit 11c detects the relative position of the obstacle and the own vehicle acquired by the external information input unit 11b, the own vehicle internal position stored in advance, and the pole object 34 determined by the display position control unit 12b. Based on the position, the relative position of the obstacle and the pole object 34 is obtained.

In the third embodiment, the control unit 12 obtains a pole distance which is a distance between an obstacle and the pole object 34 based on the relative position acquired by the external information input unit 11 b, and based on the pole distance. , Change the color of the pole object 34.

<Operation>
FIG. 14 is a flowchart showing the operation of the display control device 1 according to the third embodiment. The operation in FIG. 14 is similar to that in which step S31 is added after step S3 in FIG.

  In step S31, the control unit 12 obtains the above-described pole distance based on the relative position acquired by the external information input unit 11b, and changes the color of the pole object 34 based on the pole distance. For example, as shown in FIG. 15, when the pole distance dp between the obstacle 51 and the pole object 34 is larger than a predetermined first distance (for example, 40 cm), the control unit 12 generates a pole object Change 34 colors to a light blue or other safe color. As shown in FIG. 16, when the pole distance dp is equal to or less than the first distance and larger than a predetermined second distance (for example, 20 cm), the control unit 12 sets the pole object 34 to yellow or the like. Change to the attention color of. As shown in FIG. 17, when the pole distance dp is equal to or less than the second distance, the control unit 12 changes the color of the pole object 34 to a warning color such as red. After step S31, the process returns to step S2.

<Summary of Embodiment 3>
According to the display control device 1 according to the third embodiment as described above, the display mode of the pole object 34 is changed based on the relative position of the obstacle around the host vehicle and the pole object 34. According to such a configuration, the driver can know the relative positional relationship such as the pole distance by changing the display mode such as the color of the pole object 34 when the pole object 34 is moved.

  In the above description, the control unit 12 changes the color of the pole object 34 based on the pole distance, but the present invention is not limited to this. For example, as shown in FIG. 18, based on whether or not the portion 53 of the obstacle 51 having the shortest distance to the pole object 34 is located within a fan-shaped area 35 extending forward from the pole object 34. The controller 12 may change the color of the pole object 34.

  Also, in the above description, the display mode changed by the control unit 12 has been described as the color of the pole object 34. However, the present invention is not limited to this, and the display mode to be changed by the control unit 12 may be, for example, presence or absence of animation such as blinking of the pole object 34, color, shape, and / or pattern. .

<Variations of Embodiment 3>
Next, each modification of the third embodiment will be described. Although not described in detail, the third embodiment may be combined with each modification of the second embodiment as appropriate, or the second embodiment may be combined with each modification of the third embodiment as appropriate.

<Modification 1 of Embodiment 3>
In the third embodiment, the control unit 12 changes the display mode of the pole object 34 based on the relative position of the obstacle and the pole object 34 acquired by the relative position acquisition unit 11 c. It is not a thing. For example, the control unit 12 may change the display mode of the pole object 34 based on the relative position of the obstacle and the own vehicle acquired by the external information input unit 11 b. Specifically, the control unit 12 may change the display mode of the pole object 34 based on the distance between the obstacle and the bumper of the host vehicle. More specifically, the control unit 12 determines whether the distance between the obstacle and the bumper of the host vehicle is equal to or less than a distance (for example, 5 cm) where the possibility of the obstacle contacting the bumper is high. , The display mode of the pole object 34 may be changed.

<Modification 2 of Embodiment 3>
The periphery detection unit 23 of FIG. 13 may further detect the color of the obstacle around the host vehicle, and the outside information input unit 11b may further acquire the color of the obstacle detected by the periphery detection unit 23. Then, the control unit 12 may change the color of the pole object 34 based on the color of the obstacle acquired by the external information input unit 11 b. For example, the control unit 12 may change the color of the pole object 34 to a color that is the same as or similar to the color of the obstacle acquired by the external information input unit 11 b. The color referred to here includes not only one color but also a color tone such as a combination of a plurality of colors as described above.

  Further, the periphery detection unit 23 detects the relative position between the obstacle and the pole object 34 and the color of the obstacle for each of the plurality of obstacles around the host vehicle, and the outside information input unit 11 b detects the periphery The pieces of information detected by the unit 23 may be acquired. Then, the control unit 12 may change the color of the pole object 34 based on the relative position and color of each of the plurality of obstacles acquired by the external information input unit 11 b. For example, as shown in FIG. 19, the control unit 12 may change the color of the pole object 34 based on the color of the obstacle closest to the pole object 34 among the plurality of obstacles 51. In the example of FIG. 19, when the pole object 34 is close to the obstacle 51b, the color tone of the pole object 34 is changed to be the same as the color of the obstacle 51b, and when the pole object 34 is close to the obstacle 51c The color of the pole object 34 is changed to be the same as the color of the obstacle 51c.

  According to such a configuration, the driver can determine which part of the host vehicle is close to which obstacle, and in turn which obstacle affects the traveling of the host vehicle.

  In the example of FIG. 19, the control unit 12 changes the color of all parts of the pole object 34 based on the color of the obstacle acquired by the external information input unit 11b, but in the case limited to this Absent. For example, the control unit 12 may change the color of part of the pole object 34 (for example, the tip or the like) based on the color of the obstacle acquired by the external information input unit 11 b. Then, in this configuration, the control unit 12 may change the color of the remaining part (for example, the side surface) of the pole object 34 based on the relative position of the obstacle and the pole object 34.

<Modification 3 of Embodiment 3>
In this modification, the control unit 12 can control a display unit (not shown) different from the virtual display unit 21 that can be displayed in the host vehicle, and the periphery detection unit in FIG. 23 includes a camera. In this case, the periphery detection unit 23 may capture the periphery of the host vehicle with a camera, and the outside information input unit 11 b may obtain the image from the periphery detection unit 23. Then, the control unit 12 causes the image acquired by the external information input unit 11b to be displayed on another display unit that can be displayed in the own vehicle, and causes the display object corresponding to the pole object 34 to be superimposed on the image. Good. Note that the display object corresponding to the pole object 34 is a display object that is the same as or similar to the pole object 34.

  FIG. 20 is a diagram showing an example of an arrangement relationship between the host vehicle 2 and another vehicle 51a which is an obstacle. FIG. 21 shows the arrangement 36 of FIG. 20 in which the corresponding pole object 37, which is a display object corresponding to the pole object 34, is superimposed on the image 36 acquired by the external information input unit 11b and displayed on another display unit. It is a figure which shows a state. Since the front part of the other vehicle 51a in FIG. 20 is inclined to the left, the front part of the other vehicle 51a is strictly inclined to the left in the image, but this is not an important point, and for convenience, the image of FIG. In the figure, the front part of the other vehicle is shown not to tilt.

  According to the configuration of the present modification as described above, the driver can easily associate the scenery viewed directly with the scenery viewed from the camera by the pole object 34 and the corresponding pole object 37.

  In the above configuration, it is assumed that a general display device is used for another display unit. However, the present invention is not limited to this, and a display device capable of displaying a virtual display object using stereoscopic vision in another display unit may be used. Also, in that case, a virtual display object may be applied to the corresponding pole object 37.

<Modification 4 of Embodiment 3>
In the third embodiment, it is assumed that the control unit 12 moves the pole object 34 based on the moving operation of the driver. However, the present invention is not limited to this, and the control unit 12 automatically moves the pole object 34 from one side to the other side of the front passenger seat and the driver's seat within a range overlapping with the fender of the host vehicle and the front bumper. May be According to such a configuration, when the driver tries to know the relative positional relationship between the obstacle and the own vehicle by the change of the display mode, the driver does not need to perform the operation of moving the pole object 34. Can reduce the burden of

<Modification 5 of Embodiment 3>
The control unit 12 according to the third embodiment moves the pole object 34 within a range overlapping with the fender of the host vehicle and the front bumper, as shown by the two-dot chain line in FIGS. I did. However, the control unit 12 is not limited to this, and as shown by the solid lines in FIGS. 22 and 23, the control unit 12 separates from the fender of the host vehicle 2 and the front bumper based on the moving operation. The pole object 34 may be moved forward. A distance of, for example, about 10 cm is used as the maximum separation distance between the pole object 34 and the fender of the host vehicle 2 and the front bumper.

  According to such a configuration, even when the pole object 34 moves away from the fender of the host vehicle 2 and the front bumper, the control unit 12 can perform the operation described in the third embodiment. That is, even when the pole object 34 moves away from the fender of the host vehicle 2 and the front bumper, the control unit 12 controls the pole based on the pole distance between the obstacle around the host vehicle and the pole object 34. The display mode of the object 34 can be changed. Therefore, the driver can confirm how far the host vehicle and the obstacle are apart by moving the pole object 34 to the obstacle side.

  In addition, when the pole object 34 reaches a position where the pole object 34 comes into contact with an obstacle during this movement, the control unit 12 changes the display mode of the pole object 34 to a special display mode that indicates that the contact is made. The virtual display unit 21 may further display a display object such as a character or a graphic indicating that a touch has been made.

The pole object 34 is moved to the portion of the host vehicle 2 in contact with the obstacle when moving along the distance.

  However, the present invention is not limited to this. For example, the control unit 12 may control the own vehicle 2 based on the relative position acquired by the outside information input unit 11 b and the own vehicle movement trajectory acquired by the inside information input unit 11 d. When the vehicle moves along the vehicle movement trajectory, the pole object 34 may be moved to a portion of the vehicle 2 that is not in contact with the obstacle but comes closest to the obstacle. Or control part 12 may change the display mode of pole object 34 based on whether it contacts with an obstacle. According to such a configuration, the driver can change the movement trajectory of the own vehicle 2 so that the own vehicle 2 does not touch the obstacle, with reference to the display of the pole object 34.

  For example, as shown in FIG. 51, the control unit 12 moves the main pole object 39 to the portion 2 e closest to the other vehicle 51 a of the host vehicle 2 at the present, and the host vehicle 2 follows the host vehicle movement locus. When moving, the auxiliary pole object 38 may be moved to a portion 2 f of the host vehicle 2 in contact with an obstacle. Further, for example, the control unit 12 moves one auxiliary pole object 38 to the currently closest portion 2 e of the host vehicle 2, and when the host vehicle 2 moves along the host vehicle movement trajectory, Another auxiliary pole object 38 may be moved to the part 2f contacting with the obstacle. In this case, the control unit 12 may fix the position of the main pole object 39 at the initial position.

In this case, the outside-of-vehicle information input unit 11 b obtains a second movement trajectory, which is a future movement trajectory of the obstacle, based on the information on the obstacle around the host vehicle detected by the periphery detection unit 23. In the following description, the second movement locus is referred to as “an obstacle movement locus”.

  For example, when the obstacle is another vehicle that can not drive automatically, the outside-of-vehicle information input unit 11b moves the movement trajectory of the other vehicle to the obstacle based on the direction of the tire of the other vehicle shown in the captured image. Calculate as a locus. When the obstacle is another vehicle that can drive automatically, the outside-vehicle information input unit 11b moves the movement trajectory of the other vehicle to the obstacle based on the information of the automatic driving of the other vehicle acquired by the inter-vehicle communication or the like. Calculate as a locus.

  The control unit 12 such as the display position control unit 12b receives the relative position of the obstacle and the own vehicle acquired by the outside information input unit 11b, the own vehicle movement locus obtained by the inside information input unit 11d, and the outside information input In the case where the host vehicle moves along the host's vehicle movement track and the obstacle moves along the obstacle travel locus based on the obstacle movement track obtained by the part 11 b, the obstacle among the host vehicles At least one of the part closest to the point and the part in contact with the obstacle is determined. Then, the control unit 12 moves the pole object 34 to at least one of the obtained parts.

  According to such a configuration, it is possible to enhance the accuracy of determining the portion closest to the obstacle in the host vehicle and the accuracy of determining the portion contacting the obstacle.

<Modification 3 of Embodiment 6>
