DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments.

[0013] FIG. 1 is a schematic diagram of a vehicle according to the present embodiment. The vehicle V according to the present embodiment is an autonomous driving vehicle. Furthermore, the vehicle V can be switched between manual and automatic driving. Manual driving is a driving in which a driver operates the vehicle V to drive the vehicle V. Autonomous driving refers to a driving mode in which the vehicle V drives automatically without the operation of the occupants. However, in this embodiment, autonomous driving refers to a model in which at least a part of the driving is performed by a driver. In other words, the autonomous driving in this embodiment is based on the SAE (Society of Autonomous Engineers) f Automotive Engineers) International Furthermore, the autonomous driving in this embodiment includes levels 1 to 5. It is preferable that the level is at least one of levels 3 to 5, and the level is It is more preferable that the vehicle is at least one of the above four types. For example, it can be switched by the occupant.

[0014] The display system 1 according to this embodiment is a system mounted on a vehicle V and displays images inside the vehicle V. The inside of the vehicle V refers to, for example, the interior of the vehicle where the seats for the passengers are provided. In the present embodiment, the display system 1 includes a display device 10 and a detection device 12. The display device 10 is The detection device 12 is provided with a display unit 22 described later, and displays an image on the display unit 22. The detection device 12 is a sensor that detects the surrounding conditions of the vehicle V. is a nearby vehicle that is close to vehicle V, in other words, a vehicle that is close to vehicle V. In this case, a nearby vehicle is one that is within a predetermined detection distance from vehicle V. It can also be said that the vehicles around the vehicle V are vehicles that are present around the vehicle V. 12 detects the position of an adjacent vehicle relative to the vehicle V and the distance between the vehicle V and the adjacent vehicle. That is, the detection device 12 determines in what direction and at what distance the nearby vehicle is from the vehicle V. The detection device 12 detects whether the object is in the vicinity of the ground. However, it is not limited to this and may be any other sensor such as an imaging device. The number of the detection devices 12 and the mounting positions of the detection devices 12 on the vehicle V may also be determined by It is optional.

[0015] The display device 10 is provided in a vehicle V. FIG. 2 is a schematic diagram of the display device according to the present embodiment. Fig. 3 is a schematic diagram showing the interior of the vehicle according to the present embodiment. As shown in the figure, the display device 10 includes an input unit 20, a display unit 22, a storage unit 24, and a communication unit 26. The input unit 20 is a device that receives operations by a passenger, and is, for example, The display unit 22 is a display that displays images. As shown in FIG. 3, the display unit 22 is provided in a vehicle V. The windshield FG and handle HN are equipped. The steering wheel HN is the steering wheel operated by the driver. The display unit 22 is located at a position visible to the driver, for example, on the vertically lower side of the windshield FG. However, the display unit 22 may be provided at any position. For example, as a so-called head-up display, It may also be provided on a lathe or the like.

[0016] The storage unit 24 shown in FIG. 2 stores various information such as the contents of calculations performed by the control unit 30 and programs. For example, RAM (Random Access Memory) and R Main memory such as OM (Read Only Memory) and HDD (Hard Drive) and an external storage device such as a USB flash drive. is a communication module for communicating with an external device such as the detection device 12, and is, for example, an antenna And so on.

[0017] The control unit 30 as an image processing device is a calculation device, that is, a CPU (Central Processor). The control unit 30 is a vehicle information acquisition unit 40 and a switching information acquisition unit 41. The control unit 30 includes an information acquisition unit 42 and a display control unit 44. The vehicle information acquisition unit 40 and the switching information acquisition unit 4 2 and a display control unit 44, and executes the processes by them. These processes may be performed by a single CPU, or multiple CPUs may be provided to perform the processes. These processes may be executed by a plurality of CPUs. At least a part of the replacement information acquisition unit 42 and the display control unit 44 is realized by a hardware circuit. This is also fine.

[0018] The vehicle information acquisition unit 40 acquires information on nearby vehicles. The vehicle information acquisition unit 40 controls the detection device 12 to acquire information on nearby vehicles. The detection device 12 acquires information about the approaching vehicle detected. In this embodiment, the vehicle information acquisition unit 4 0 is information on the nearby vehicles, including the position of the nearby vehicles relative to vehicle V and the distance between vehicle V and the nearby vehicles. The vehicle information acquisition unit 40 also acquires information other than the information on the nearby vehicles. For example, the vehicle information acquisition unit 40 may use a GPS (Global Positioning System). By communicating with the GPS Navigation System, the vehicle V's geographic coordinates and map information can be obtained. do.

[0019] In this embodiment, the vehicle information acquisition unit 40 acquires information on nearby vehicles from the detection device 12. However, the method of acquiring information on nearby vehicles is not limited to the above. Information on nearby vehicles may be obtained from an external device not provided on either vehicle. For example, The information acquisition unit 40 may communicate with the GPS and acquire information on nearby vehicles from the GPS. In addition, when a sensor for detecting a vehicle is provided on a road or the like, the vehicle information acquisition unit 40 may obtain information about nearby vehicles from this sensor.

[0020] The switching information acquisition unit 42 acquires switching information. The switching information is transmitted to the display control unit 44. This information is used to determine whether to switch the image displayed on the display unit 22. The driving mode information and the driving situation information are acquired as the switching information. is information indicating the driving mode of the vehicle V. That is, the switching information acquisition unit 42 As the mode information, information on whether the vehicle V is in manual driving mode or autonomous driving mode is obtained. If the vehicle V is currently set to the manual driving mode, the switching information acquisition unit 42 The vehicle V acquires driving mode information indicating that the vehicle V is currently in the autonomous driving mode. If the driving mode is set to the automatic driving mode, driving mode information indicating that the driving mode is the automatic driving mode is obtained.

[0021] The driving condition information is information that indicates the condition in which the vehicle V is driving. obtains information on whether the vehicle V is in the first state or the second state as the driving situation information. The first state is when the driver feels uneasy about the autonomous driving mode. The second state refers to the state in which the vehicle V is traveling. A state in which the degree of anxiety about driving is smaller than in the first state and the vehicle V is traveling. In other words, the second state refers to a state in which the occupants are not aware of the automatic driving in the automatic driving mode. This refers to a state in which vehicle V is traveling in a situation where there is little traffic congestion.

[0022] The switching information acquisition unit 42 acquires information on whether the state is the first state or the second state by any method. For example, whether the occupant is in the first state or the second state may be input to the input unit 20 or the like. In this case, for example, if the passenger feels uneasy about the automated driving, In this case, the driver is not worried about the automatic driving when the driver is in the first state and the driver is not worried about the automatic driving. If the driver inputs the second state, the switching information acquisition unit 42 inputs the second state. By doing so, information on whether the state is the first state or the second state is acquired. The input is not limited to two stages, either the first state or the second state, but can be any of two or more. The input unit 20 may be a dial, a lever, a plurality of buttons (two stages (For floors, the number 1 button is also acceptable), touch panel, etc. Any number of steps greater than 2 can be entered. If there are more than two stages, then either in the first state or in the second state is preferred. The presence or absence of the vehicle occupant is judged based on whether or not the vehicle occupant is at or above a threshold level that is preset for each vehicle occupant. You may do so.

[0023] Further, for example, the switching information acquisition unit 42 determines whether the vehicle is in the first state or the second state based on the biological information of the occupant. In this case, for example, the display system 1 may acquire information on the biological information of the occupant. The switching information acquisition unit 42 is provided with a sensor for detecting biological information of the occupant by the sensor. Based on the result of the information detection, it is judged whether the state is the first state or the second state. For example, the sensor The heart rate of the passenger may be measured. In this case, the switching information acquisition unit 42 may be configured to If the driver's heart rate is above the threshold, the driver is deemed to be anxious about autonomous driving. If the driver determines that the vehicle is in the first state and the driver's heart rate is below the threshold, the driver is not worried about the autonomous driving. The driver may determine that the driver does not remember the state and that the driver is in the second state. In this case, the switching information acquisition unit 42 may be configured to detect the The frequency with which the occupant's gaze is directed outside the vehicle and exceeds a threshold, or the frequency with which the occupant changes gaze direction If the threshold value is exceeded, the vehicle is determined to be in the first state, and the driver is not allowed to look outside the vehicle. The time spent looking at something was less than the threshold, or the frequency of changing the direction of gaze was less than the threshold. In the case where the handle HN is turned on, the state may be determined to be the second state. , brake pedal, and accelerator pedal, etc., for driving the vehicle V. In this case, the switching information acquisition unit 42 may be configured to detect whether the occupant is touching the switch. If the time that the occupant touches the operation device is equal to or longer than the threshold, the state is determined to be the first state, and If the time during which the user touches the operation device is less than the threshold, the user may determine that the operation device is in the second state. .

[0024] Further, for example, the switching information acquisition unit 42 may determine whether the vehicle V is in the first state based on the location where the vehicle V is traveling. In this case, the switching information acquisition unit 42 may acquire information on whether the vehicle is in the first state or the second state. The switching information acquisition unit 42 acquires information on the location where the V is traveling. For example, the switching information acquisition unit 42 acquires information on the location where the V is traveling from the GPS. The earth coordinates of the vehicle V are acquired, and the vehicle V's current travel direction is calculated based on the map information and the earth coordinates of the vehicle V. Then, the switching information acquisition unit 42 detects the location where the vehicle V is currently traveling. For example, the switching information acquisition unit 42 When the vehicle V is traveling in a place where it has never been before, it is determined that the vehicle V is in the first state. If the vehicle is traveling in a place that it has traveled before, it may be determined that the vehicle is in the second state. The places you have traveled to before are places on your route that you regularly travel to, such as your home, workplace, or school. It is preferable that the location where the first state is determined and the location where the second state is determined are preset. These predefined locations may be set as locations on a predetermined route. It may be a place within a certain distance from any point, or within an arbitrary administrative district. In this case, the switching information acquisition The unit 42 judges the vehicle V to be in the first state when the vehicle V is traveling in a place where the vehicle V is judged to be in the first state. If the vehicle V is traveling in a place that is determined to be in the second state, the vehicle V should be determined to be in the second state. For example, the switching information acquisition unit 42 may use the information of the nearby vehicle acquired by the vehicle information acquisition unit 40. For example, the switching information acquisition unit may determine whether the state is the first state or the second state based on the 42 determines that the vehicle is in the first state when the number of adjacent vehicles is equal to or greater than the threshold value, and If it is less than the value, it may be determined that the second state is present.

[0025] FIG. 4 is a diagram showing an example of an image displayed on the display unit. The display control unit 44 controls the display unit 22 As shown in FIG. 4, in this embodiment, the display control unit 44 controls the display unit 2 to display an image. 2 displays images P, PM1, and PM2. Image P is an image showing the driving situation of vehicle V. The image showing the driving situation of the vehicle V is an image showing the driving situation of the vehicle V. In other words, it is an image showing the surroundings of the vehicle V. The display contents of the image P will be described later. The images PM1 and PM2 are images showing the traveling state of the vehicle V. In the example of FIG. PM1 is a speedometer showing the speed of the vehicle V, and image PM2 shows the number of revolutions of the vehicle V. The display control unit 44 displays the images P, PM1, and PM2 simultaneously on one screen. For example, the display control unit 44 detects that the image P is located between the images PM1 and PM2. However, the display control unit 44 displays the images P, PM1, and PM2 so that the images P, PM1, and PM2 are displayed in the same manner. The display of PM1 and PM2 is not limited to being on a single screen. For example, the display control unit 44 may Image P may be displayed alone on the screen, or image P may be displayed alongside an image showing other information. This is also fine.

[0026] The display control unit 44 controls the display unit 2 based on the information on the nearby vehicle acquired by the vehicle information acquisition unit 40. 2 to display an image P. The display control unit 44 also The display content of the image P is changed based on the change information. The image P will be described in more detail below. do.

[0027] The display control unit 44 switches the display content of the image P based on the driving mode information in the switching information. Specifically, the display control unit 44 switches the driving mode information to the manual driving mode. When the vehicle is in the manual driving mode, the image P is displayed as the manual driving image PA. When V is in the automatic driving mode, the first image PB or the second image P is used as the image P. C is displayed. The first image PB and the second image PC are images showing nearby vehicles.

[0028] 5 is a diagram showing an example of a manual driving image PA. The manual driving image PA shows a driving route of a vehicle V. The display control unit 44 displays the navigation screen as the vehicle V moves. Route information indicating the route and vehicle position information indicating the position of the vehicle V on the route are displayed on a manual driving image. More specifically, the manual driving image PA is displayed as a vehicle position image A1 and a vehicle position image A2. The image includes a road image A2, an accident location image A3, a traffic jam route image A4, and a delay time image A5. .

[0029] The vehicle position image A1 is an image showing the position of the vehicle V on the route along which the vehicle V is traveling. The route image A2 is an image showing the route along which the vehicle V travels. The display control unit 44 displays the vehicle V information acquired by the vehicle information acquisition unit 40. Based on the earth coordinates and map information, a vehicle position image A1 and a route image A2 are generated and displayed. For example, the display control unit 44 displays the destination and map of the vehicle V set by the occupant on the display unit 22. Based on this information, a route for the vehicle V is set, and the set route is displayed as a route image A2. Then, the display control unit 44 detects the current position of the vehicle V on the route from the earth coordinates of the vehicle V. The current position of the vehicle V on the route is displayed as a vehicle position image A1. The route of both V is not limited to being set by the display control unit 44. For example, the display control unit 44 may The information on the route set by the control devices of both V may be acquired and displayed as the route image A2. .

[0030] The vehicle position image A1 is displayed so as to overlap with the route image A2. The current position of the vehicle V is , which is the start point of the route at the current time, the route image A2 is The route image A2 is displayed as an image of a route connecting the vehicle V and the destination. Accordingly, the display is updated so as to scroll in the traveling direction of the vehicle V.

[0031] The accident location image A3 is a location where the vehicle V is traveling when a traffic accident occurs on the route along which the vehicle V is traveling. The image A3 shows the location of a traffic accident on the route. The display control unit 44 receives, for example, a traffic Acquire information on the location where the accident occurred, and generate an accident location image A3 based on that information. The information is displayed on the display unit 22.

[0032] The congested route image A4 is an image showing a congested section on the route along which the vehicle V is traveling. The congested route image A4 is displayed so as to be superimposed on the route image A2. In a manner that can be distinguished from the route image A2 without traffic jams, in other words, the route image without traffic jams For example, the image A4 shows a route without traffic jams. The display control unit 44 receives, for example, a traffic jam notification from an external device. Based on the information, a congestion route image A4 is generated and displayed. Can.

[0033] The delay time image A5 is a current arrival schedule of the vehicle V at the destination with respect to the original arrival schedule. Displays the delay time for a scheduled time. For example, the original estimated arrival time is the time when traffic congestion is not taken into account. The current estimated arrival time is the estimated arrival time when traffic congestion is taken into account. The display control unit 44 calculates the latest estimated arrival time from information on the congested section, etc. The display control unit 44 calculates the difference between the calculated estimated arrival time and the original estimated arrival time. This difference is displayed as a delay time image A5.

[0034] The display control unit 44 thus displays the manual driving image PA on the display unit 22. The manual driving image PA described above is an example, and the display contents of the manual driving image PA are not limited to the above description. Not limited.

[0035] 6 and 7 are diagrams showing an example of the first image. When the driving mode information indicates that the vehicle V is in an autonomous driving mode, P, the first image PB or the second image PC is displayed. In the case of the automatic driving mode, the driving situation information in the switching information indicates the first state. In other words, the display control unit 44 causes the display unit 22 to display the first image PB when the vehicle When both vehicles are operating in autonomous mode and the occupants are uneasy about autonomous driving The first image PB is an image showing an approaching vehicle. The first image PB will now be described in detail.

[0036] The display control unit 44 displays the first image based on the information of the nearby vehicle acquired by the vehicle information acquisition unit 40. PB is generated and displayed on the display unit 22. As shown in FIG. 6, the first image PB is an overhead view. The overhead image is a vertical image of the vehicle V viewed from above. This refers to an image when it is assumed that both V and nearby vehicles are seen. The display control unit 44 acquires vehicle information The position of the adjacent vehicle relative to the vehicle V and the distance between the vehicle V and the adjacent vehicle acquired by the unit 40 Based on this, the display control unit 44 detects the positional relationship between the vehicle V and the nearby vehicles. Based on the positional relationship between V and nearby vehicles, vehicle V and nearby vehicles are viewed from above in the vertical direction. A bird's-eye view image as if seen from the viewpoint is generated as a first image PB and displayed on the display unit 22. Since the first image PB is an overhead view image, the image is displayed on the front side of the traveling direction of the vehicle V (the traveling direction In addition to the image of the nearby vehicle located in the area behind the vehicle V in the direction of travel (the direction of travel), The images also include images of nearby vehicles located within the area (opposite the vehicle direction).

[0037] The first image PB includes a vehicle image B0, a vehicle lane image B1, a side lane image B2, and a nearby lane image B3. The vehicle image B0 is an image showing the vehicle V. The vehicle lane image B The side lane image B1 is an image showing the route on which the vehicle V is traveling. The image B3 shows a nearby vehicle. The side here refers to the side when the traveling direction of the vehicle V is the forward direction. In FIG. 6, the vehicle lane image B1 and the side lane image B2 are lanes in the same direction. The lanes do not necessarily have to be in the same direction, but may be in opposite directions.

[0038] The display control unit 44 displays the host vehicle image B0 so as to overlap the host vehicle lane image B1. For example, the vehicle image B0 is displayed on the vehicle lane image B1 as an image that mimics the shape of the vehicle. The display control unit 44 acquires information on the route of the vehicle V, and displays the route of the vehicle V based on the information on the route. An image B0, an own vehicle lane image B1, and a side lane image B2 may be generated and displayed. The position of the vehicle image B0 in the first image PB is fixed, and the position of the vehicle image B0 changes according to the movement of the vehicle V. In addition, for the subject vehicle image B0, the subject vehicle lane image B1, the side lane image B2, and the adjacent vehicle lane image B3 are At least one of the images B0 and B3 may be changed so as to move relatively. The position to be fixed within one image PB is not limited to the center of the first image PB, but can be to the left or right of the center. The first image PB may be fixed at a biased position, and the amount of information displayed on the first image PB may be increased. Decide the fixing position based on the lane, number of lanes, number of vehicles traveling, etc. Good too.

[0039] The display control unit 44 displays the adjacent lane image B1 or the side lane image B2 so as to overlap with the own vehicle lane image B1 or the side lane image B2. For example, the nearby vehicle image B3 is an image that mimics the shape of a vehicle. The display control unit 44 displays the first image P based on the positional relationship between the vehicle V and the nearby vehicles. The display control unit 44 calculates the position of the nearby vehicle relative to the vehicle V on the first screen B. The image PB is displayed at the calculated position of the nearby vehicle. Thus, a vehicle within a predetermined detection distance range of the vehicle V is detected as a nearby vehicle. In this case, the display control unit 44 displays all of the vehicles within the detection distance range of the vehicle V, i.e., All of the detected nearby vehicles may be displayed as the nearby vehicle image B3. The control unit 44 detects nearby vehicles within a predetermined distance range that is shorter than the detection distance range of the vehicle V. For example, when the number of vehicles within the detection distance range is equal to or greater than a predetermined number, the vehicle approaching image B3 may be displayed. When the vehicle V is moving faster than the specified speed, the vehicle V may move faster than the specified speed. Alternatively, the nearby vehicle within the range may be displayed as a nearby vehicle image B3. As shown in FIG. 6, the display control unit 44 detects the forward side in the traveling direction of the host vehicle image B0 and the traveling direction of the vehicle V. The adjacent vehicles on both the left and right sides of the row are displayed as adjacent vehicle images B3. The display control unit 44 displays nearby vehicles located in all directions relative to the vehicle V as nearby vehicle images B3. Display.

[0040] In addition, the display control unit 44 detects a reckless vehicle and distinguishes the reckless vehicle from an adjacent vehicle that is not a reckless vehicle. The dangerous vehicle is a vehicle V that is at high risk of colliding with other vehicles. For example, the display control unit 44 may detect an adjacent vehicle that may be at risk of colliding with the vehicle V. The vehicle is judged to be a dangerous vehicle. The following are the dangerous vehicles that are at risk of colliding with vehicle V. The display control unit 44 displays the vehicle V at a distance of a threshold value. The display control unit 44 may determine that a nearby vehicle having a value equal to or smaller than the threshold value is a first reckless vehicle. , a nearby vehicle that is approaching vehicle V and whose distance to vehicle V is less than or equal to a threshold value. The display control unit 44 may determine that the vehicle V is a first dangerous vehicle. The relative speed is equal to or greater than a predetermined value, the vehicle is approaching the vehicle V, and the distance between the vehicle V and the vehicle V is A nearby vehicle whose distance is equal to or less than a threshold may be determined as a first risk vehicle. Since there is a risk of collision with the vehicle V, the display control unit 44 displays the vehicle V differently from other nearby vehicles. The display content is displayed so that the occupants can easily recognize it. are not limited to these.

[0041] In addition, the display control unit 44 detects whether the vehicle V is colliding with another nearby vehicle based on the behavior of the nearby vehicle. Vehicles that are close enough to cause a collision are considered dangerous vehicles. , the dangerous vehicle that may result in a collision between vehicle V and other nearby vehicles is appropriately classified as the second dangerous vehicle. For example, a vehicle V enters the lane in front of it from another lane. If vehicle V brakes to keep a safe distance from the vehicle in front of it, In that case, the distance between vehicle V and the vehicle behind it becomes shorter, and the distance between vehicle V and the vehicle behind it becomes shorter. The risk of collision increases. Therefore, if there is a vehicle in front of the lane V, If a vehicle enters the area from the other side, that vehicle may be determined as the second hazardous vehicle. For example, the display control unit 44 may display an adjacent vehicle traveling ahead of the vehicle V in the lane on the side of the vehicle V. When a vehicle detects that the vehicle is moving toward the lane of the vehicle V, the vehicle V is determined to be a second dangerous vehicle. In addition, for example, the display control unit 44 determines that the vehicle V is traveling several vehicles ahead of the vehicle V in the same lane. If a vehicle that is moving along the road suddenly decelerates, the vehicle is classified as a second hazardous vehicle. In this case, for example, the display control unit 44 may determine that the vehicle V is in the same lane as the vehicle V, and that the vehicle V is in the same lane as the vehicle V. The relative speed of an adjacent vehicle traveling in the same direction to vehicle V is greater than or equal to a predetermined value in the direction approaching vehicle V. If it is detected that the vehicle is above the second risk vehicle, the vehicle is determined to be a second risk vehicle. Such a second dangerous vehicle increases the risk of collision between other vehicles and vehicle V, so the display control The display unit 44 displays the information differently from other nearby vehicles, so that the passengers can easily recognize the information. However, the method of determining whether a vehicle is a second hazardous vehicle is not limited to the above.

[0042] In addition, the display control unit 44 displays the first reckless vehicle and the second reckless vehicle with different display contents. FIG. 6 shows a case where an adjacent vehicle traveling ahead of vehicle V in the lane to the side of vehicle V An example of a first image PB at the time when a vehicle V is about to move to the lane side is shown. FIG. 7 shows the first image after the adjacent vehicle moves into the lane of vehicle V. 6, the display control unit 44 displays an example of a lane PB on the side of the vehicle V. is traveling ahead of vehicle V and is attempting to move into vehicle V's lane. The nearby vehicle is determined to be a second reckless vehicle and is displayed as a nearby vehicle image B3a. The nearby vehicle image B3a showing the hazardous vehicle is a nearby vehicle image B3 that is not determined to be a hazardous vehicle. For example, the nearby vehicle image B3a is displayed as a dangerous vehicle. The adjacent vehicle image B3a is displayed in a color different from that of the adjacent vehicle image B3 that is not displayed. The image B3 of a nearby vehicle that is not determined to be a dangerous vehicle and is displayed in yellow, may be colored, for example, in gray, black, It may be displayed in blue or the like.

[0043] The second hazardous vehicle entered the lane of vehicle V, causing vehicle V to slow down and collide with the vehicle behind. As shown in FIG. 7, the display control unit 44 displays the distance between the vehicle V and the vehicle The vehicle behind the vehicle whose distance is less than the threshold is determined to be the first dangerous vehicle and is taken as the nearby vehicle image B. The nearby vehicle image B3b showing the first reckless vehicle is displayed as a nearby vehicle image B3b showing the first reckless vehicle. The image B3 of the nearby vehicle B1 is displayed with different display contents from the image B2 of the nearby vehicle B2. The adjacent vehicle image B3b showing the second dangerous vehicle is displayed in a different manner from the adjacent vehicle image B3a showing the second dangerous vehicle. For example, the nearby vehicle image B3b is a nearby vehicle that is not determined to be a dangerous vehicle. The image B3 and the nearby vehicle image B3a indicating the second dangerous vehicle are displayed in different colors. The vehicle image B3b may be displayed in red, for example.

[0044] The display control unit 44 thus causes the first image PB to be displayed on the display unit 22. The first image PB described above is just an example, and the display contents of the first image PB are not limited to those described above.

[0045] Next, the second image PC will be described. FIG. 8 to FIG. 12 are diagrams showing an example of the second image. The display control unit 44 determines whether the vehicle V is in an automatic driving mode in the driving mode information of the switching information. When the driving status information in the switching information indicates the second state, In this case, the display control unit 44 displays the second image PC on the display unit 22. , When the vehicle V is driving in autonomous driving mode and the occupants feel uneasy about the autonomous driving If the overlap is small, the second image PC is displayed. The second image PC displays the nearby vehicle. This is an image.

[0046] The second image PC has less information than the first image PB. indicates the amount of information on nearby vehicles to be displayed. That is, the second image PC has more information than the first image PB. ,The amount of information displayed about nearby vehicles is small.,Moreover, if vehicle V is in the same situation, i.e., vehicle When the relative positional relationship between V and the adjacent vehicle is the same, the first image PB and the second image PC are If the number of nearby vehicles displayed in the second image PC is assumed to be displayed, the number of nearby vehicles displayed in the first image PB will be In this embodiment, the second image PC shows the number of vehicles in front of the vehicle V. This is an image showing the other side of the road, showing an approaching vehicle from the viewpoint of vehicle V looking forward in the direction of travel. The display control unit 44 is configured to display the proximity information for the vehicle V acquired by the vehicle information acquisition unit 40. Based on the position of the approaching vehicle and the distance between the vehicle V and the adjacent vehicle, the position of the vehicle V and the adjacent vehicle is calculated. Then, the display control unit 44 detects the positional relationship between the vehicle V and the nearby vehicles. The image of the nearby vehicle as seen from the viewpoint of the vehicle V looking ahead in the traveling direction is taken as the second The second image PC is generated as an image of the vehicle V in the forward direction and displayed on the display unit 22. Since the image is looking at the vehicle V, the image of the nearby vehicle located in the forward area in the traveling direction of the vehicle V is not However, images of nearby vehicles located in the rear area of ​​the vehicle V in the traveling direction are not included. That is, the second image PC is an image of a nearby vehicle located in the rear area in the traveling direction of the vehicle V. Since both images are not included, the amount of information displayed about the nearby vehicles is The number of images is smaller than that of the first image PB.

[0047] 8 and 9 show the second image PC when the nearby vehicle is not displayed. As shown in FIG. 1, the second image PC includes an own vehicle lane image C1, a side lane image C2, and a situation information image C3. In this embodiment, the second image PC includes an image of the vehicle V, which is the vehicle itself. No image included.

[0048] The vehicle lane image C1 is an image showing the route on which the vehicle V is traveling. C2 is an image showing a route on the side of the route on which the vehicle V is traveling. calculates the width of the route on which the vehicle V is traveling based on the width of the vehicle V, The area obtained by extending the width of the route in the direction of travel D of the vehicle V is set as the route on which the vehicle V is traveling. Then, the display control unit 44 displays the set route on which the vehicle V is traveling in the vehicle lane image. For example, the display control unit 44 may display the image C1 on the display unit 22. The width on both sides of the road that is wider than the designated length is the width of the route on which the vehicle V is traveling. When lanes are set by lines or the like, the display control unit 44 displays the lane in which the vehicle V is traveling. The area between the white lines on both sides of the lane may be the vehicle lane image C1. In FIG. 4, a side lane image C2 is positioned on the side of the vehicle lane image C1 generated in this way. In the example of FIG. 8, the side lane image C2 is generated and displayed. The image C2 is a side lane image C2a on one side of the vehicle lane image C1 and a side lane image C2b on the other side of the vehicle lane image C1. However, the number of the side lane images C2 is not limited to this. It is set according to the road on which the vehicle V is traveling. For example, if the road has two lanes, the side lane There may be only one image C2.

[0049] The situation information image C3 is an image showing the situation of an approaching vehicle on the side of the vehicle V. In other words, it is displayed on the side of the vehicle lane image C1. The area corresponding to the side edge of the main image C1 (the path on which the vehicle V is traveling) is defined as the side CL. The side CL is also called a region indicating the boundary between the vehicle lane image C1 and the side lane image C2. The situation information image C3 is formed along the side CL. The image C3 is a virtual wall-like image extending vertically upward from the side CL in the second image PC. The situation information image C3 is formed as an image of the vehicle from the end C3S to the end C3T. The situation information image C3 extends toward the front side in the traveling direction D of the vehicle V. From S to the end C3T, the side of the vehicle lane image C1 (the path on which the vehicle V is traveling) is blocked. The end C3S is displayed as a wall-like image that extends in the direction D of travel of the vehicle V. For example, the vehicle V may be set at the same position as the front end of the vehicle V in the traveling direction D of the vehicle V. The end C3T may be set at a position forward of the end C3S in the traveling direction D of the vehicle V. The situation information image C3 may be set at any position. Therefore, the nearby vehicle image C4 on the side lane image C2 described later is displayed as a situation information image. Even if the image C3 overlaps with the image C4, the image C4 can be seen. Since side lane images C2a and C2b are provided on both sides of the lane image C1, The situation information image C3 is formed between the vehicle lane image C1 and the side lane image C2a. The situation information image C3a and the situation information image formed between the vehicle lane image C1 and the side lane image C2b. and a situation information image C3b.

[0050] 10 to 12 show the second image PC when there is an adjacent vehicle in front of the vehicle V. As shown in FIG. 10, the second image PC includes a nearby vehicle image C4. The display control unit 44 controls the display of the vehicle lane image C1 or the side image C2. The nearby vehicle image C4 is displayed so as to overlap with the lane image C2. For example, The display control unit 44 controls the vehicle V and the nearby vehicle C4 to be displayed as an image that resembles the shape of the vehicle. Based on the positional relationship between the two vehicles, the second image PC is displayed based on the position of the nearby vehicles. The vehicle V is located in the forward area of ​​the traveling direction D of the vehicle V. Then, the display control unit 44 calculates the position of the calculated proximity on the second image PC. In this case, the display control unit 44 displays the nearby vehicle image C4 at the position of the vehicle V. The vehicle is located within a forward area in the traveling direction D and within a predetermined display distance range from the vehicle V. The vehicle is displayed as a nearby vehicle image C4. This indicates the upper limit of the distance between the vehicle V and the adjacent vehicle when it is displayed as the vehicle image C4. As described above, a vehicle within the detection distance range of vehicle V is detected as a nearby vehicle. The display distance in this embodiment may be set arbitrarily, but may be set to, for example, a value that is shorter than the detection distance. That is, the display control unit 44 may set the area on the front side in the traveling direction D of the vehicle V to be shorter than the area on the front side in the traveling direction D of the vehicle V. Among the nearby vehicles in the display distance range, the nearby vehicles are displayed as nearby vehicle images C4. However, the display distance may be set to the same length as the detection distance. The display control unit 44 displays all of the nearby vehicles in the area ahead of the vehicle V in the traveling direction D as the nearby vehicles. In either case, the display control unit 44 displays the vehicle image B A nearby vehicle in the area ahead in the traveling direction of vehicle 0 is displayed as a nearby vehicle image B3.

[0051] The display control unit 44 controls the display contents of the situation information image C3 and the nearby vehicle image C4 described above. The situation information image C3 is changed according to the positional relationship between the vehicle V and the nearby vehicle. Regardless of the presence or absence of the vehicle, or the display of the nearby vehicle image C4, the second image is displayed on the PC. The display content changes depending on the distance to the vehicle V. The display control unit 44 displays the display content of the vehicle V on the side of the vehicle V. In the first situation, the approaching vehicle is located closer to vehicle V, and in the second situation, the approaching vehicle is located closer to the side of vehicle V than in the first situation. In the second situation, the vehicle V is positioned farthest from the first situation, and the display content of the situation information image C3 is made different between these two situations. In this embodiment, the first situation is a situation in which the distance between the adjacent vehicle and the vehicle V is within a predetermined distance range. The second situation refers to a situation in which the distance between the adjacent vehicle and the vehicle V is outside a predetermined distance range. That is, when the nearby vehicle on the side of the vehicle V is within a predetermined distance range, the display control unit 44 The situation information image C3 on the side where the nearby vehicle is located is displayed in the first mode, and the situation information image C4 on the side of the nearby vehicle V is displayed in the second mode. When the nearby vehicle on the opposite side is outside the predetermined distance range, the situation information image C3 is displayed in a different manner from the first manner. That is, for example, when a nearby vehicle on one side (for example, the right side) is If it is outside the fixed distance range, the situation information image C3a on one side (for example, the right side) is displayed as the first image. The first and second modes are arbitrary display modes as long as the display contents are different. However, in this embodiment, the display control unit 44 uses different colors for the first and second modes. For example, the display control unit 44 may set the status information image C3 in the first state to red and the status information image C4 in the second state to red. The information image C3 may be colored blue. The situation information image C3 of the second embodiment may be made to blink, and the situation information image C3 of the first embodiment may not be made to blink.

[0052] The display control unit 44 displays the adjacent vehicle on the side regardless of the position of the adjacent vehicle on the side relative to the vehicle V. When the two are within a predetermined distance range, the situation information image C3 is displayed in the first manner. In the case where the adjacent vehicle on the side is located in the area behind the vehicle V, the display control unit 44 Even if the vehicle is located in the forward area of ​​the vehicle V, if the vehicle is within a predetermined distance range, The situation information image C3 is displayed in the first manner. The processing distance here is set arbitrarily. However, for example, it may be set to the same length as the display distance indicating the maximum distance at which the nearby vehicle image C4 is displayed. It may be determined.

[0053] 8 to 11 show a vehicle V approaching from behind on one side (here, the right side) of the vehicle V. When an approaching vehicle approaches and passes vehicle V, it moves away from the front. FIG. 8 shows an example of a second image PC. In this example, the display control unit 44 is located at the rear of the vehicle V. In order not to display nearby vehicles in the rear area, the second image PC shown in FIG. In the example of FIG. 8, the vehicle C4 is not displayed. In the area behind both Vs, it is located outside the specified distance range. The situation information image C3a is displayed in the second manner. Since there is no vehicle within the fixed distance range, the situation information image C3b shown in FIG. It is displayed in a second manner.

[0054] FIG. 9 shows that the adjacent vehicle in the lane on one side of the vehicle V is closer to the vehicle V than in FIG. 8. In FIG. 9, the vehicle V is located behind the vehicle V. The adjacent vehicle image C4 is not displayed because it is located to the side of the vehicle V. The vehicle is located within a certain distance range in the rear area. Therefore, the situation information shown in FIG. The image C3a is displayed in the first mode. In this way, in the second image PC, In this case, the situation information image C3a of the vehicle is displayed in the first mode, so that the occupant It is possible to detect the approach of a vehicle.

[0055] FIG. 10 shows a state in which a nearby vehicle in one lane on one side of vehicle V has overtaken vehicle V. That is, FIG. 10 shows a vehicle V in a front area and on one side of the vehicle V. In FIG. 10, an example is shown in which there is an adjacent vehicle. In FIG. 10, the adjacent vehicle is a Since the vehicle is located within the display distance range from both V, the vehicle on one side is shown as a nearby vehicle image C4. The vehicle V is displayed on the side lane image C2a. Since it is located within the range, the situation information image C3a is displayed in the first manner.

[0056] FIG. 11 shows that an adjacent vehicle in one lane on one side of vehicle V is moving further away from vehicle V than in the state shown in FIG. In FIG. 11, the adjacent vehicle is also located within a predetermined distance range from the vehicle V. Since the situation information image C3a is located within the range, the situation information image C3a is displayed in the first manner. In the case of 11, the adjacent vehicle is located within the display distance range from vehicle V, so In this embodiment, the display control unit 44 displays the vehicle image C4. The display content of the nearby vehicle image C4 is changed according to the distance between the nearby vehicle and the vehicle V. In this case, the display control unit 44 increases the transparency of the nearby vehicle image C4 as the nearby vehicle moves away from the vehicle V. In other words, the closer the nearby vehicle is to the vehicle V, the more opaque the nearby vehicle image C4 becomes. The further the nearby vehicle is from the vehicle V, the more transparent the nearby vehicle image C4 becomes. The display control unit 44 then determines whether the distance between the nearby vehicle and the vehicle V is displayed as a display distance. When the distance becomes longer than the distance, the transparency of the nearby vehicle image C4 is maximized, and the nearby vehicle image C4 In FIG. 11, the adjacent vehicle is farther away from the vehicle V than in the state of FIG. However, this nearby vehicle is located within the display distance range. The adjacent vehicle image C4 shown in FIG. 10 is more transparent than the adjacent vehicle image C4 shown in FIG. 10, but is not completely transparent. It is not highlighted, but is displayed semi-transparently.

[0057] When the adjacent vehicle in the lane on one side of the vehicle V moves further away from the vehicle V than in FIG. 11 In this case, the second image PC is displayed as shown in FIG. Since the vehicle is located in front of the vehicle V and outside the predetermined distance range from the vehicle V, the situation information image C3a is In this case, the display is switched from the first state to the second state. Since the vehicle is located outside the display distance range from the vehicle V ahead in the traveling direction D, the nearby vehicle image C 4 becomes completely transparent and is no longer displayed.

[0058] If the length from the end C3S to the end C3T of the situation information image C3 is the wall length, The wall length may be set arbitrarily. For example, the wall length may be set to a value equal to the display distance at which the nearby vehicle image C4 is displayed. In this case, the vehicle in front of the vehicle V may be located forward of the end C3T. When the vehicle moves to the next vehicle, the nearby vehicle image C4 of the nearby vehicle becomes invisible, and the situation information image C3 switches from the first mode to the second mode.

[0059] In the explanation of FIG. 8 to FIG. 11, the change in the second image PC when there is an adjacent vehicle on the side of the vehicle V is On the other hand, Fig. 12 shows an example of the second case where there is a nearby vehicle in the same lane as vehicle V. An example of an image PC is shown. Even if there is a nearby vehicle in the same lane as vehicle V, The change in the display content of the image C4 is similar to the change shown in FIG. 8 to FIG. 11. The vehicle image C4 displays nearby vehicles within the display distance range in the area ahead of the vehicle V. The further away from vehicle V is, the more transparent it becomes. If both are present, the display content of the side CL will change instead of the side situation information image C3. That is, when a nearby vehicle in the same lane as the vehicle V is within a predetermined distance range, the display control unit 44 The side CL is displayed in the first mode, and a nearby vehicle in the same lane as the vehicle V is outside the predetermined distance range. In this case, the side CL is displayed in the second manner. The first and second manners of the side CL are different in that the display content is Any display mode may be used as long as it is different, but in this embodiment, the display control unit 44 selects the first mode For example, the display control unit 44 colors the side CL in the first aspect in red. In addition, the side CL of the second embodiment may be colored blue.

[0060] FIG. 12 shows a case where a nearby vehicle ahead of the vehicle V is in the same lane as the vehicle V and is within a predetermined distance range. In this case, the sides CLa and CLb are displayed in the first mode. The vehicle ahead of vehicle V is in the same lane as vehicle V, but is within the displayed distance range. The nearby vehicle image C4 is displayed on the line C1 image. In this case, the nearby vehicle image C4 is The display contents may be different, such as being lit up or turned on. When a nearby vehicle is outside the predetermined distance range, for example, as shown in FIG. a, CLb are displayed in the second manner.

[0061] In this way, the side CL is expressed as follows according to the distance between the vehicle V and the adjacent vehicles in the same lane as the vehicle V: That is, the situation information image C3 changes to show the situation of the nearby vehicle on the side of the vehicle V. The side CL is a situation information image showing the situation of an adjacent vehicle in the same lane as the vehicle V. It can be said to be an information image.

[0062] The display control unit 44 thus causes the second image PC to be displayed on the display unit 22. The above-described second image PC is merely an example, and the display contents of the second image PC are not limited to those described above.

[0063] As described above, the display control unit 44 displays the manual driving image PA and the second driving image PA in response to the switching information. The display control unit 44 switches between the first image PB and the second image PC. It is preferable to seamlessly switch between the image PA, the first image PB, and the second image PC. In the above description, the display control unit 44 displays the manual driving image P in the manual driving mode. A is displayed, and in the automatic driving mode, the first image PB and the second image PC are displayed. However, the driving mode when the manual driving image PA, the first image PB, and the second image PC are displayed For example, in the manual driving mode, the manual driving image PA and the first image PB In the automatic driving mode, the manual driving image may be displayed by switching between the first image PC and the second image PC. The image PA, the first image PB, and the second image PC may be displayed in a switching manner. The vehicle is not limited to being capable of switching between manual and automatic driving modes, and may be, for example, For example, the vehicle may be one that cannot be autonomous. In the case of such a vehicle, it is either in the first state or the second state. The judgement of whether the driver is in a state of mind is based not on the level of anxiety the driver feels about the autonomous driving, but on the level of anxiety the driver feels about the surroundings. You can make your decision based on how much you want to understand the situation.

[0064] In this embodiment, the entire display device 10 including the control unit 30 is provided in the vehicle V. However, for example, the control unit 30 may be configured as a display control device separate from the display device 10. In addition, the display unit 2 may be provided outside the vehicle V, not in the vehicle V. 2 receives images from a control unit 30 outside the vehicle V through communication and displays them. At least the vehicle information acquisition unit 40, the switching information acquisition unit 42, and the display control unit 44 of the control unit 30 Some of them may not be provided on the vehicle V.

[0065] Next, the image switching flow of the display device 10 will be described with reference to a flowchart. 13 is a flowchart illustrating the image switching flow according to this embodiment. As shown in FIG. 13, the control unit 30 acquires switching information by the switching information acquisition unit 42 ( Step S10). The switching information acquisition unit 42 receives the switching information indicating that the vehicle V is in manual driving mode. driving mode information indicating whether the vehicle V is in a first state or a second state; The control unit 30 acquires driving status information indicating whether the vehicle is in a driving state or not based on the switching information. It is determined whether V is in the manual driving mode or the automatic driving mode (step S12). If the mode is the driving mode (step S12; Yes), the display control unit 44 displays a manual driving screen. The image PA is displayed on the display unit 22 (step S14). For example, if the first image PB or the second image PC is currently being displayed, the display control unit 44 The display content can be seamlessly switched from the first image PB or the second image PC to the manual driving image PA. can.

[0066] On the other hand, if the operation mode is not the manual operation mode (step S12; No), that is, if the operation mode is the automatic operation mode In this case, the control unit 30 determines whether the vehicle V is in the first state or the second state based on the switching information. If it is in the first state (step S16; Yes), The control unit 30 causes the display control unit 44 to display the first image PB on the display unit 22 (step In step S18, for example, the current manual driving image PA or the second image PC is If the image P is currently being displayed, the display control unit 44 changes the display content of the image P to the current manual driving image PA or Seamlessly switch from the second image PC to the first image PB. On the other hand, if the first state is not present, (Step S16; No), that is, in the second state, the control unit 30 4, the second image PC is displayed on the display unit 22 (step S20). In the example, if the manual driving image PA or the first image PB is currently displayed, the display control The control unit 44 changes the display contents of the image P from the current manual driving image PA or the first image PB to the second image Switch to PC seamlessly. After performing steps S14, S18, and S20, The process proceeds to step S15. If the process is to be ended (step S15; Yes), the process is ended. If not finished (step S15; No), the process returns to step S10 and continues.

[0067] As described above, the control unit 30 as a display control device according to the present embodiment controls the vehicle V A vehicle information acquisition unit 40 acquires information on nearby vehicles, and a nearby vehicle information acquisition unit 41 acquires information on nearby vehicles based on the information on the nearby vehicles. The display control unit 44 displays an image showing an approaching vehicle. A first image PB showing a vehicle and a nearby vehicle with less information than the first image PB. The display device mounted on the vehicle V switches between the first image PC and the second image PC. When displaying information on nearby vehicles on the display unit 22, the information on nearby vehicles is appropriately displayed according to the situation of the vehicle V. In response to this, the control unit 30 according to the present embodiment is required to display the nearby vehicle. The first image PB to be displayed and a nearby vehicle displayed with less information than the first image PB The control unit 30 according to the present embodiment switches between the first image PC and the second image PC. According to the method, the first image PB and the second image PC can be switched depending on the situation of the vehicle V. This makes it possible to provide different amounts of information about nearby vehicles to the occupants depending on the situation of vehicle V. Therefore, according to the control unit 30 of this embodiment, the proximity Vehicle information can be displayed appropriately.

[0068] Furthermore, for example, when the vehicle V is driving in the autonomous driving mode, the occupants may The situation of the vehicle V may change, such that the driver may feel anxious at times and less anxious at other times. For example, if a passenger feels uneasy about the autonomous driving, they may choose to stay in the autonomous driving mode. Even if they are driving alone, people tend to want to have more information about nearby vehicles. If the driver is not concerned about the surrounding vehicles, he or she does not need to obtain as much information about the surrounding vehicles. The control unit 30 according to the embodiment switches between the first image PB and the second image PC. For example, if a passenger feels uneasy about autonomous driving, The first image PB is displayed to provide more information about nearby vehicles, reducing passenger anxiety about autonomous driving. If the driver does not remember the vehicle, the second image PC can be displayed to reduce the amount of information on nearby vehicles. Therefore, according to the control unit 30 according to the present embodiment, the vehicle V performing automatic driving is It is particularly effective.

[0069] In addition, the display control unit 44 controls the number of adjacent vehicles displayed in the second image PC to be the same as that of the vehicle V. In this situation, the number of nearby vehicles displayed when the first image PB is displayed will be less than the number of nearby vehicles displayed when the first image PB is displayed. According to the control unit 30 of the present embodiment, the second image PC is displayed. Since it is possible to change the number of nearby vehicles to be displayed depending on the situation of vehicle V, Depending on the situation, information about nearby vehicles can be displayed appropriately.

[0070] The display control unit 44 also displays the nearby vehicle from a viewpoint looking down on the vehicle V from above in the vertical direction. The image shown in FIG. 1 is displayed as a first image PB, and is taken from a viewpoint looking forward in the traveling direction D from the vehicle V. The image showing the nearby vehicle is displayed as the second image PC. In this case, by making the first image PB an overhead image, it is possible to prevent the driver from feeling uneasy about the autonomous driving. In this case, by providing the occupant with information on nearby vehicles in the entire surroundings of the vehicle V, the occupant can This allows drivers to get sufficient information about approaching vehicles, which helps ease their anxiety. According to the control unit 30, by making the second image PC an image looking forward, for example, when the occupant automatically When the driver is not anxious about driving, reducing the amount of information about nearby vehicles can help prevent information overload. This can reduce the risk of feeling that it is too much.

[0071] In addition, the display control unit 44 increases the distance of the approaching vehicle from the vehicle V in the second image PC. The transparency of the nearby vehicle image C4 (image of the nearby vehicle) is increased to make the distance between the nearby vehicle and vehicle V clear. When the distance is equal to or greater than a predetermined distance, the control unit 30 stops displaying the nearby vehicle. The transparency of the nearby vehicle image C4 increases as the vehicle moves away from the vehicle. This allows occupants to be properly informed while reducing the risk of them feeling overwhelmed with information.

[0072] In addition, the display control unit 44 displays a situation information image showing the situation of the nearby vehicle in the second image PC. According to the control unit 30, by displaying the situation information image, the driver can easily get on the nearby vehicle. This allows the crew to be appropriately informed while reducing the risk of the crew feeling overwhelmed with information.

[0073] In addition, the display control unit 44 may also select a first situation in which the nearby vehicle is located close to the vehicle V, and a second situation in which the nearby vehicle is The display contents of the situation information image are different between the second situation, which is farther from the vehicle V than the first situation, and the second situation, which is farther from the vehicle V than the first situation. According to the control unit 30, the situation information image is changed depending on whether the nearby vehicle is close or far away. This allows the driver to be aware of nearby vehicles while avoiding overloading the driver with information. It can be suppressed.

[0074] The display control unit 44 displays the situation information image C3 on the side of the vehicle V. The image is displayed as a virtual wall showing the situation of nearby vehicles. By displaying the situation information image C3, the occupant can see that the route on which the vehicle V is traveling is surrounded by walls. The image of the wall changing and changing the sign on the wall makes the driver feel safe. Therefore, according to the control unit 30, Depending on the situation of vehicle V, information about nearby vehicles can be displayed appropriately.

[0075] In addition, the display control unit 44 displays in the first image PB a risk of the vehicle V colliding with another vehicle. A dangerous vehicle, which is a nearby vehicle that increases the risk of being attacked, is displayed with display contents different from those of other nearby vehicles. According to the control unit 30, the display content of the reckless vehicle in the first image PB is changed. For example, in situations where passengers are unsure about autonomous driving, the system can provide more accurate information about nearby vehicles. It will be possible to provide.

[0076] In addition, when the vehicle V is in the autonomous driving mode, the display control unit 44 displays the vehicle V according to the driving conditions of the vehicle V.
