That is, the detection device 12 detects, with respect to the vehicle V, in which direction and at what distance a neighboring vehicle is located. The detection device 12 is, for example, a LIDAR (Light Detection and Ranging) sensor, but is not limited thereto, and may be any device such as an imaging device. Also, the number of detection devices 12 and the mounting position of the detection device 12 on the vehicle V are arbitrary.

[0015] The display device 10 is provided in the vehicle V. FIG. 2 is a schematic block 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 FIG. 2, the display device 10 includes an input unit 20, a display unit 22, a storage unit 24, a communication unit 26, and a control unit 30. The input unit 20 is a device that receives an operation by an occupant, and is, for example, a touch panel or operation buttons. The display unit 22 is a display that displays an image . As shown in FIG. 3, the display unit 22 is provided inside the vehicle V. Inside the vehicle V, a front glass FG and a steering wheel HN are provided. The front glass FG is also called a front windshield and a windscreen. The steering wheel HN is a steering wheel operated by a driver. The display unit 22 is provided at a position visible to the driver, for example, on the lower side in the vertical direction of the front glass FG . However, the position where the display unit 22 is provided may be arbitrary. The display unit 22 may be provided on the front glass FG, a side glass, or the like as a so-called head-up display, for example.

[0016] The storage unit 24 shown in FIG. 2 stores various information such as the calculation content and programs of the control unit 30. is a memory, for example, a main memory device such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and includes at least one of external memory devices such as an HDD (Hard Disk Drive). The communication unit 26 is a communication module that communicates with an external device such as the detection device 12, and is, for example, an antenna etc. etc.

[0017] The control unit 30 as an image processing device is an arithmetic unit, that is, a CPU (Central Processing Unit). The control unit 30 includes a vehicle information acquisition unit 40, a switching information acquisition unit 42, and a display control unit 44. The control unit 30 reads and executes a program (software) from the storage unit 24 to realize the vehicle information acquisition unit 40, the switching information acquisition unit 4 2, and the display control unit 44, and executes the processing by them. Note that the control unit 30 may execute these processes by one CPU, or may include a plurality of CPUs and execute these processes by these plurality of CPUs. Further, at least a part of the vehicle information acquisition unit 40, the switching information acquisition unit 42, and the display control unit 44 may be realized by a hardware circuit

[0018] The vehicle information acquisition unit 40 acquires information on nearby vehicles. The vehicle information acquisition unit 40 controls the detection device 12 to cause the detection device 12 to acquire information on nearby vehicles. The vehicle information acquisition unit 40 acquires information on nearby vehicles detected by the detection device 12. In the present embodiment, the vehicle information acquisition unit 4 0 acquires, as information on nearby vehicles, the position of a nearby vehicle with respect to the vehicle V and the distance between the vehicle V and the nearby vehicle This is possible. For example, the vehicle information acquisition unit 40 acquires the global coordinates, map information, etc. of the vehicle V by communicating with the GPS (Global Positioning System).

[0019] In this embodiment, the vehicle information acquisition unit 40 acquires the information of the neighboring vehicle from the detection device 12, but the method for acquiring the information of the neighboring vehicle is not limited thereto. The vehicle information acquisition unit 40 may acquire the information of the neighboring vehicle from an external device not provided in the vehicle V. For example, the vehicle information acquisition unit 40 may communicate with the GPS and acquire the information of the neighboring vehicle from the GPS. Also, when a sensor for detecting a vehicle is provided on a road or the like, the vehicle information acquisition unit 40 may acquire the information of the neighboring vehicle from this sensor.

[0020] The switching information acquisition unit 42 acquires switching information. The switching information is information for determining whether the display control unit 44 switches the image to be displayed on the display unit 22. The switching information acquisition unit 42 acquires the driving mode information and the driving situation information as the switching information. The driving mode information is information indicating the driving mode of the vehicle V. That is, the switching information acquisition unit 42 acquires information indicating whether the vehicle V is in the manual driving mode or the automatic driving mode as the driving mode information. When the vehicle V is currently set to the manual driving mode, the switching information acquisition unit 42 acquires the driving mode information indicating that it is the manual driving mode, and when the vehicle V is currently set to the automatic driving mode, the switching information acquisition unit 42 acquires the driving mode information indicating that it is the automatic driving mode.

[0021] The driving situation information is information indicating the situation in which the vehicle V is driving. The switching information acquisition unit 42 ​​​​​​​​​​​​​​As driving condition information, obtain information on whether the vehicle V is in the first state or the second state. . The first state refers to a situation where, in the autonomous driving mode, the occupant feels uneasy about the autonomous driving, and the vehicle V is in a driving state. The second state refers to a situation where, in the autonomous driving mode, the degree to which the occupant feels uneasy about the autonomous driving is smaller than that in the first state, and the vehicle V is in a driving state. That is, the second state refers to a situation where, in the autonomous driving mode, the uneasiness of the occupant with respect to the autonomous driving is small, and the vehicle V is in a driving state.

[0022] The switching information acquisition unit 42 may obtain information on whether it is in the first state or the second state by any method. For example, it may be possible to set whether the occupant is in the first state or the second state to be inputtable to the input unit 20 or the like. In this case, for example, when the occupant feels uneasy about the autonomous driving, the occupant inputs to the input unit 20 or the like that it is in the first state, and when the occupant does not feel uneasy about the autonomous driving, the occupant inputs that it is in the second state. Then, the switching information acquisition unit 42 obtains information on whether it is in the first state or the second state by detecting the input of the occupant. Note that the input to the input unit 20 is not limited to two steps of whether it is in the first state or the second state, and may be input in any number of steps of two or more. The input unit 20 is preferably a device capable of inputting any number of steps of two or more, such as a dial, a lever, a plurality of buttons (even one button in the case of two steps), a touch panel, etc. When there are more than two steps, whether it is in the first state or the second state may be determined by whether it is equal to or greater than a threshold value set in advance for each occupant.

[0023] Also, for example, the switching information acquisition unit 42 determines whether it is in the first state or the second state based on the biometric 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. Obtain information on the location where vehicle V is traveling. For example, the switching information acquisition unit 42 obtains, from the GPS, the geodetic coordinates of vehicle V, and based on the map information and the geodetic coordinates of vehicle V, detects the location where vehicle V is currently traveling . Then, the switching information acquisition unit 42 determines whether it is in the first state or the second state from the location where vehicle V is currently traveling. For example, if vehicle V is traveling at a location where it is traveling for the first time, the switching information acquisition unit 42 may determine that it is in the first state, and if it is traveling at a location where it has traveled before, it may determine that it is in the second state. Here, the location where it has traveled before is preferably a location on a route where it moves regularly, such as home, workplace, or school. Also, the locations determined to be in the first state and the locations determined to be in the second state may be preset. These preset locations may be set as locations on a predetermined route, or may be locations within a certain distance range from an arbitrary point, locations within the range of an arbitrary administrative division, locations within the range surrounded by an arbitrary road, etc. In this case, when vehicle V is traveling at a location determined to be in the first state, the switching information acquisition unit 42 determines that it is in the first state, and when vehicle V is traveling at a location determined to be in the second state, it may determine that it is in the second state. Also, for example, the switching information acquisition unit 42 may determine whether it is in the first state or the second state based on the information of the surrounding vehicles acquired by the vehicle information acquisition unit 40. For example, when the number of surrounding vehicles is equal to or greater than the threshold value, the switching information acquisition unit 42 may determine that it is in the first state, and when the number of surrounding vehicles is less than the threshold value, it may determine that it is in the second state.

[0025] FIG. 4 is a diagram showing an example of an image to be displayed on the display unit. The display control unit 44 controls the display unit 22 ​​​​​​​​​​​​​​The image is displayed on the display unit 2. As shown in FIG. 4, in this embodiment, the display control unit 44 causes the display unit 2 to display the images P, PM1, and PM2. The image P is an image showing the driving status of the vehicle V . The image showing the driving status of the vehicle V is an image showing in what situation the vehicle V is driving, in other words, an image showing the situation around the vehicle V. The display content of the image P will be described later . The images PM1 and PM2 are images showing the driving state of the vehicle V. In the example of FIG. 4, the image PM1 is a speedometer showing the speed of the vehicle V, and the image PM2 is a tachometer showing the rotational speed of the vehicle V . The display control unit 44 simultaneously displays the images P, PM1, and PM2 on one screen . For example, the display control unit 44 displays the images P, PM1, and PM2 such that the image P is located between the image PM1 and the image PM2 . However, the display control unit 44 is not limited to displaying the images P, PM1, and PM2 on one screen. For example, the display control unit 44 may display only the image P on one screen, or may display the image P side by side with an image displaying other information . The display control unit 44 causes the display unit 2 to display the image P based on the information of the neighboring vehicle acquired by the vehicle information acquisition unit 40. Further, the display control unit 44 switches the display content of the image P based on the switching information acquired by the switching information acquisition unit 42. Hereinafter, the image P will be described in more detail

[0026] . The display control unit 44 switches the display content of the image P based on the driving mode information in the switching information. Specifically, when the vehicle V is assumed to be in the manual driving mode in the driving mode information, the display control unit 44 displays the manual driving image PA as the image P, and the vehicle .

[0027] . In the case where the vehicle V is in the automatic driving mode, the display control unit 44 displays the automatic driving image PB as the image P . ​When V is in the automatic driving mode, as the image P, the first image PB or the second image P C is displayed. The first image PB and the second image PC are images that display the surrounding vehicles.

[0028] FIG. 5 is a diagram showing an example of a manual driving image. The manual driving image PA is a so-called navigation screen that displays the driving route of the vehicle V. The display control unit 44 displays the route information indicating the route along which the vehicle V travels and the own vehicle position information indicating the position of the vehicle V on the route as the manual driving image PA. More specifically, the manual driving image PA includes the own vehicle position image A1, the route image A2, the accident position image A3, the traffic jam route image A4, and the delay time image A5. .

[0029] The own vehicle position image A1 is an image showing the position of the vehicle V on the route along which the vehicle V travels, and can also be said to be the own vehicle position information. The route image A2 is an image showing the route along which the vehicle V travels and can also be said to be the route information. The display control unit 44 generates the own vehicle position image A1 and the route image A2 based on the global coordinates of the vehicle V acquired by the vehicle information acquisition unit 40 and the map information, and causes the display unit 22 to display them. For example, the display control unit 44 sets the route of the vehicle V from the destination of the vehicle V set by the occupant and the map information, and displays the set route as the route image A2. Then, the display control unit 44 detects the current position of the vehicle V on the route from the global coordinates of the vehicle V, and displays the current position of the vehicle V on the route as the own vehicle position image A1. However, the route of the vehicle V is not limited to being set by the display control unit 44. The display control unit 44 may, for example, acquire the route information set by the control device of the vehicle V and display it as the route image A2. .

[0030] ​​​​ The own-vehicle position image A1 is displayed so as to overlap the route image A2. The current position of the vehicle V is , and since it is the starting point of the route at the current time, the route image A2 is displayed as an image of the route connecting from the own-vehicle position image A1 to the end point of the route. Further, the route image A2 is updated so as to scroll in the traveling direction side of the vehicle V as the vehicle V travels.

[0031] The accident position image A3 is an image showing the position where a traffic accident has occurred on the route on which the vehicle V travels when a traffic accident occurs on the route on which the vehicle V travels. The accident position image A3 is displayed so as to overlap on the route image A2. The display control unit 44 acquires information on the position where a traffic accident has occurred from, for example, an external device, and based on that information, generates the accident position image A3 and displays it on the display unit 22.

[0032] The traffic jam route image A4 is an image showing a section where the vehicle V is in a traffic jam on the route on which the vehicle V travels. The traffic jam route image A4 is displayed so as to overlap on the route image A2. The traffic jam route image A4 is displayed in a distinguishable manner from the non-traffic jam route image A2, in other words, with a display content different from that of the non-traffic jam route image A2. For example, the traffic jam route image A4 is displayed in a color different from that of the non-traffic jam route image A2. The display control unit 44 acquires information on the section where there is a traffic jam from, for example, an external device, and based on that information, generates the traffic jam route image A4 and displays it.

[0033] The delay time image A5 displays the delay time of the current arrival prediction time with respect to the initial arrival prediction time of the vehicle V at the destination. For example, the initial arrival prediction time is the case without taking traffic jams into account. It is the scheduled arrival time, but the current scheduled arrival time is the scheduled arrival time considering traffic congestion. The display control unit 44 calculates the latest scheduled arrival time from information such as the section with traffic congestion and calculates the difference between the calculated scheduled arrival time and the initial scheduled arrival time. The display control unit 44 displays this difference as the delay time image A5.

[0034] The display control unit 44 causes the manual driving image PA to be displayed on the display unit 22 in this way. However, the manual driving image PA described above is an example, and the display content of the manual driving image PA is not limited to the above description.

[0035] FIGS. 6 and 7 are diagrams showing an example of the first image. When the vehicle V is in the automatic driving mode in the driving mode information in the switching information, the display control unit 44 displays the first image PB or the second image PC as the image P. Further, when the vehicle V is in the automatic driving mode and the driving situation information in the switching information indicates the first state, the display control unit 44 displays the first image PB on the display unit 22. That is, when the vehicle V is running in the automatic driving mode and the passenger feels uneasy about the automatic driving, the display control unit 44 displays the first image PB. The first image PB is an image that displays the surrounding vehicles. Hereinafter, the first image PB will be specifically described.

[0036] The display control unit 44 generates the first image PB based on the information of the surrounding vehicles acquired by the vehicle information acquisition unit 40 and displays it on the display unit 22. As shown in FIG. 6, the first image PB is displayed as an overhead view image. The overhead view image refers to an image assuming that the vehicle V and the surrounding vehicles are viewed from a viewpoint looking down on the vehicle V from above in the vertical direction. The display control unit 44 acquires vehicle information​​​​​​​ The position of the neighboring vehicle with respect to the vehicle V and the distance between the vehicle V and the neighboring vehicle, which are acquired by the unit 40 Based on this, the positional relationship between the vehicle V and the neighboring vehicle is detected. Then, the display control unit 44 Based on the positional relationship between the vehicle V and the neighboring vehicle, assuming a viewpoint looking down from directly above in the vertical direction at the vehicle V and the neighboring vehicle generates an overhead image as the first image PB when viewed from the viewpoint, and causes the display unit 22 to display it. Since the first image PB is an overhead image, in addition to the image of the neighboring vehicle located within the area on the front side (the advancing direction side) of the advancing direction of the vehicle V, the image of the neighboring vehicle located within the area on the rear side (the side opposite to the advancing direction) of the advancing direction of the vehicle V is also included.

[0037] The first image PB includes the own vehicle image B0, the own vehicle lane image B1, the side lane image B2, and the neighboring vehicle image B3. The own vehicle image B0 is an image showing the vehicle V. The own vehicle lane image B 1 is an image showing the route on which the vehicle V is traveling. The side lane image B2 is an image showing the route on the side of the route on which the vehicle V is traveling. The neighboring vehicle image B3 is an image showing the neighboring vehicle. Here, the side refers to the side when the advancing direction of the vehicle V is regarded as the front. Note that in FIG. 6, the own vehicle lane image B1 and the side lane image B2 are lanes in the same direction, but they are not limited to the same direction and may be lanes in the opposite direction.

[0038] The display control unit 44 causes the own vehicle image B0 to be displayed so as to overlap with the own vehicle lane image B1. For example, the own vehicle image B0 is displayed on the own vehicle lane image B1 as an image imitating the shape of the vehicle. The display control unit 44 acquires information on the route of the vehicle V and, based on the route information, generates and displays the own vehicle image B0, the own vehicle lane image B1, and the side lane image B2. ​​​​​​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. , a dangerous vehicle that may cause a collision between the vehicle V and other nearby vehicles is appropriately referred to as a second dangerous vehicle. For example, when there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, in order to maintain a distance from that vehicle, the vehicle V may apply the brakes. In that case, the distance between the vehicle V and the vehicle behind it becomes short, increasing the risk of collision between the vehicle V and the vehicle behind it. Therefore, when there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, that vehicle may be determined as a second dangerous vehicle. In this case, for example, when the display control unit 44 detects that a nearby vehicle traveling in a lane beside the vehicle V and ahead of the vehicle V moves to the side of the lane of the vehicle V, it determines that the vehicle V is a second dangerous vehicle. Also, for example, when there is a vehicle traveling several vehicles ahead in the same lane as the vehicle V and that vehicle suddenly decelerates, that vehicle may be determined as a second dangerous vehicle. In this case, for example, when the display control unit 44 detects that the relative speed of a nearby vehicle traveling several vehicles ahead in the same lane as the vehicle V with respect to the vehicle V becomes a predetermined value or more in the direction approaching the vehicle V, it determines that the nearby vehicle is a second dangerous vehicle. Such a second dangerous vehicle increases the risk of collision between other vehicles and the vehicle V. Therefore, the display control unit 44 causes it to be displayed with a display content different from that of other nearby vehicles so that it is easier for the occupant to recognize. Note that the method for determining the second dangerous vehicle is not limited to these. For example, when there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, in order to maintain a distance from that vehicle, the vehicle V may apply the brakes. In that case, the distance between the vehicle V and the vehicle behind it becomes short, increasing the risk of collision between the vehicle V and the vehicle behind it. Therefore, when there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, that vehicle may be determined as a second dangerous vehicle. In this case, for example, when the display control unit 44 detects that a nearby vehicle traveling in a lane beside the vehicle V and ahead of the vehicle V moves to the side of the lane of the vehicle V, it determines that the vehicle V is a second dangerous vehicle. Also, for example, when there is a vehicle traveling several vehicles ahead in the same lane as the vehicle V and that vehicle suddenly decelerates, that vehicle may be determined as a second dangerous vehicle. In this case, for example, when the display control unit 44 detects that the relative speed of a nearby vehicle traveling several vehicles ahead in the same lane as the vehicle V with respect to the vehicle V becomes a predetermined value or more in the direction approaching the vehicle V, it determines that the nearby vehicle is a second dangerous vehicle. Such a second dangerous vehicle increases the risk of collision between other vehicles and the vehicle V. Therefore, the display control unit 44 causes it to be displayed with a display content different from that of other nearby vehicles so that it is easier for the occupant to recognize. Note that the method for determining the second dangerous vehicle is not limited to these. Also, the display control unit 44 displays the first dangerous vehicle and the second dangerous vehicle with different display contents. FIG. 6 shows a nearby vehicle traveling in a lane beside the vehicle V and ahead of the vehicle V. When there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, in order to maintain a distance from that vehicle, the vehicle V may apply the brakes. In that case, the distance between the vehicle V and the vehicle behind it becomes short, increasing the risk of collision between the vehicle V and the vehicle behind it. Therefore, when there is a vehicle invading from another lane in front of the lane where the vehicle V is traveling, that vehicle may be determined as a second dangerous vehicle. In this case, for example, when the display control unit 44 detects that a nearby vehicle traveling in a lane beside the vehicle V and ahead of the vehicle V moves to the side of the lane of the vehicle V, it determines that the vehicle V is a second dangerous vehicle. Also, for example, when there is a vehicle traveling several vehicles ahead in the same lane as the vehicle V and that vehicle suddenly decelerates, that vehicle may be determined as a second dangerous vehicle.

[0042] In this case, for example, when the display control unit 44 detects that the relative speed of a nearby vehicle traveling several vehicles ahead in the same lane as the vehicle V with respect to the vehicle V becomes a predetermined value or more in the direction approaching the vehicle V, it determines that the nearby vehicle is a second dangerous vehicle. Such a second dangerous vehicle increases the risk of collision between other vehicles and the vehicle V. Therefore, the display control unit 44 causes it to be displayed with a display content different from that of other nearby vehicles so that it is easier for the occupant to recognize. An example of the first image PB at the timing when the vehicle V is about to move to the lane side is shown in the figure. And FIG. 7 shows an example of the first image PB after the adjacent vehicle has moved into the lane of the vehicle V. As shown in FIG. 6, the display control unit 44 is traveling ahead of the vehicle V on the lane on the side of the vehicle V and is about to move to the lane side of the vehicle V. The adjacent vehicle is determined to be a second dangerous vehicle and is displayed as the adjacent vehicle image B3a. The adjacent vehicle image B3a indicating the second dangerous vehicle is displayed with different display contents from the adjacent vehicle image B3 for which it has not been determined to be a dangerous vehicle. For example, the adjacent vehicle image B3a is displayed in a different color from the adjacent vehicle image B3 for which it has not been determined to be a dangerous vehicle. The adjacent vehicle image B3a is, for example displayed in yellow, and the adjacent vehicle image B3 for which it has not been determined to be a dangerous vehicle may be displayed in, for example, gray, black , blue, or the like.

[0043] As a result of the second dangerous vehicle entering the lane of the vehicle V, the vehicle V may decelerate, and the distance between the vehicle V and the vehicle behind it may become shorter. As shown in FIG. 7, the display control unit 44 determines a vehicle behind the vehicle V whose inter-vehicle distance has become equal to or less than the threshold value as a first dangerous vehicle and displays it as the adjacent vehicle image B 3b. The adjacent vehicle image B3b indicating the first dangerous vehicle is displayed with different display contents from the adjacent vehicle image B3 for which it has not been determined to be a dangerous vehicle. Further, the adjacent vehicle image B3b indicating the first dangerous vehicle is also displayed with different display contents from the adjacent vehicle image B3a indicating the second dangerous vehicle. For example, the adjacent vehicle image B3b is displayed in a different color from the adjacent vehicle image B3 for which it has not been determined to be a dangerous vehicle and the adjacent vehicle image B3a indicating the second dangerous vehicle. The adjacent vehicle image B3b may be displayed in, for example, red.

[0044] ​ The display control unit 44 causes the first image PB to be displayed on the display unit 22 in this manner. However, the first image PB described above is just an example, and the display content of the first image PB is not limited to the above description. The first image PB described above is just an example, and the display content of the first image PB is not limited to the above description.

[0045] Next, the second image PC will be described. FIGS. 8 to 12 are diagrams showing an example of the second image. The display control unit 44 causes the second image PC to be displayed on the display unit 22 when the vehicle V is in the automatic driving mode in the driving mode information in the switching information and the driving situation information in the switching information indicates the second state. That is, the display control unit 44 causes the second image PC to be displayed when the vehicle V is traveling in the automatic driving mode and the degree to which the occupant feels uneasy about the automatic driving is small. The second image PC is an image that displays nearby vehicles. causes the second image PC to be displayed when the vehicle V is traveling in the automatic driving mode and the degree to which the occupant feels uneasy about the automatic driving is small.

The second image PC is an image that displays nearby vehicles. is an image that displays nearby vehicles.

[0046] The second image PC is an image with less information content than the first image PB. Here, the information content refers to the information content of the nearby vehicles to be displayed. That is, the second image PC has less information content of the nearby vehicles to be displayed than the first image PB. Further, if the vehicle V is in the same situation, that is, assuming that the first image PB and the second image PC are displayed when the relative positional relationship between the vehicle V and the nearby vehicles is the same, the number of nearby vehicles displayed in the second image PC is less than the number of nearby vehicles shown in the first image PB. In the present embodiment, the second image PC is an image showing the front side of the vehicle V, and can be said to be an image showing nearby vehicles from the viewpoint of looking ahead in the traveling direction from the vehicle V. The display control unit 44 is based on the position of the nearby vehicles with respect to the vehicle V acquired by the vehicle information acquisition unit 40 and the distance between the vehicle V and the nearby vehicles, and determines the position between the vehicle V and the nearby vehicles. assuming that the first image PB and the second image PC are displayed when the relative positional relationship between the vehicle V and the nearby vehicles is the same, the number of nearby vehicles displayed in the second image PC is less than the number of nearby vehicles shown in the first image PB.

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 may use the area sandwiched between the white lines on both sides of the lane in which the vehicle V is traveling as the own-vehicle lane image C1. The display control unit 44 generates and displays a side lane image C2 so that the side lane image C2 is positioned on the side of the own-vehicle lane image C1 generated in this way. In the example of FIG. 8, the side lane image C2 includes a side lane image C2a on one side of the own-vehicle lane image C1 and a side lane image C2b on the other side. However, the number of side lane images C2 is not limited to this and is set according to the road on which the vehicle V is traveling. For example, in the case of a two-lane road, the side lane image C2 may be one. The situation information image C3 is an image showing the situation of the neighboring vehicles on the side of the vehicle V and is displayed on the side of the vehicle V, that is, on the side of the own-vehicle lane image C1. Here, the area corresponding to the side of the own-vehicle lane image C1 (the route on which the vehicle V is traveling) is defined as the side CL. The side CL can also be said to be an area indicating the boundary between the own-vehicle lane image C1 and the side lane image C2. The situation information image C3 is formed along the side CL. Furthermore, the situation information image C3 is formed as a virtual wall-like image extending vertically upward in the second image PC from the side CL. The situation information image C3 extends from the end C3S to the end C3T toward the front side in the traveling direction D of the vehicle V. Therefore, the situation information image C3 is displayed as a wall-like image that shields the side of the own-vehicle lane image C1 (the route on which the vehicle V is traveling) from the end C3S to the end C3T. The end C3S may be set at an arbitrary position in the traveling direction D of the vehicle V. For example, it may be at the same position as the tip of the vehicle V in the traveling direction D of the vehicle V. The display control unit 44 generates and displays a side lane image C2 so that the side lane image C2 is positioned on the side of the own-vehicle lane image C1 generated in this way.

[0049] The side CL can also be said to be an area indicating the boundary between the own-vehicle lane image C1 and the side lane image C2. The situation information image C3 is formed along the side CL. Furthermore, the situation information image C3 is formed as a virtual wall-like image extending vertically upward in the second image PC from the side CL. The situation information image C3 extends from the end C3S to the end C3T toward the front side in the traveling direction D of the vehicle V. Therefore, the situation information image C3 is displayed as a wall-like image that shields the side of the own-vehicle lane image C1 (the route on which the vehicle V is traveling) from the end C3S to the end C3T. The end C3S may be set at an arbitrary position in the traveling direction D of the vehicle V. For example, it may be at the same position as the tip of the vehicle V in the traveling direction D of the vehicle V. The display control unit 44 generates and displays a side lane image C2 so that the side lane image C2 is positioned on the side of the own-vehicle lane image C1 generated in this way. In the example of FIG. 8, the side lane image C2 includes a side lane image C2a on one side of the own-vehicle lane image C1 and a side lane image C2b on the other side. However, the number of side lane images C2 is not limited to this and is set according to the road on which the vehicle V is traveling. For example, in the case of a two-lane road, the side lane image C2 may be one. It may be set to a position. Also, the end portion C3T is on the front side of the end portion C3S in the traveling direction D of the vehicle V and may be set to an arbitrary position. Note that since the situation information image C3 is displayed as an image having a predetermined transparency, the proximity vehicle image C4 on the side lane image C2 described later can be visually recognized even when it is at a position overlapping the situation information image C3. Also, in the example of FIG. 8, since the side lane images C2a and C2b are provided on both sides of the own vehicle lane image C1, the situation information image C3 includes a situation information image C3a formed between the own vehicle lane image C1 and the side lane image C2a, and a situation information image C3b formed between the own vehicle lane image C1 and the side lane image C2b. Also, in the example of FIG. 8, since the side lane images C2a and C2b are provided on both sides of the own vehicle lane image C1, the situation information image C3 includes a situation information image C3a formed between the own vehicle lane image C1 and the side lane image C2a, and a situation information image C3b formed between the own vehicle lane image C1 and the side lane image C2b. the situation information image C3 is formed between the own vehicle lane image C1 and the side lane image C2a, and a situation information image C3b formed between the own vehicle lane image C1 and the side lane image C2b. the situation information image C3 is formed between the own vehicle lane image C1 and the side lane image C2a, and a situation information image C3b formed between the own vehicle lane image C1 and the side lane image C2b. the situation information image C3 includes a situation information image C3a formed between the own vehicle lane image C1 and the side lane image C2a, and a situation information image C3b formed between the own vehicle lane image C1 and the side lane image C2b.

That is, the display control unit 44 may cause a nearby vehicle within the display distance range among the nearby vehicles in the area on the front side of the traveling direction D of the vehicle V to be displayed as the nearby vehicle image C4. However, the display distance may be set to the same length as the detection distance. In this case, the display control unit 44 may cause all of the nearby vehicles in the area on the front side of the traveling direction D of the vehicle V to be displayed as the nearby vehicle image C4. In any case, the display control unit 44 causes a nearby vehicle in the area on the front side of the traveling direction of the own vehicle image B0 to be displayed as the nearby vehicle image B3. Here, as described above, a vehicle within the detection distance range with respect to the vehicle V is detected as a nearby vehicle. The display distance in the present embodiment may be arbitrarily set. For example, it may be set shorter than the detection distance.

Here, as described above, a vehicle within the detection distance range with respect to the vehicle V is detected as a nearby vehicle. The display control unit 44 changes the display contents of the situation information image C3 and the nearby vehicle image C4 described above according to the positional relationship between the vehicle V and the nearby vehicle. The situation information image C3 is displayed on the second image PC regardless of the presence or absence of a nearby vehicle and the display of the nearby vehicle image C4, but the display contents change according to the distance between the nearby vehicle and the vehicle V. The display control unit 44 makes the display contents of the situation information image C3 different between a first situation where a nearby vehicle on the side of the vehicle V is at a position close to the vehicle V and a second situation where a nearby vehicle on the side of the vehicle V is at a position farther from the vehicle V than the first situation. In the present embodiment, the first situation refers to a situation where the distance between the nearby vehicle and the vehicle V is within a predetermined distance range, and the second situation refers to a situation where the distance between the nearby vehicle and the vehicle V is outside the predetermined distance range.

[0051] The display control unit 44 changes the display contents of the situation information image C3 and the nearby vehicle image C4 described above according to the positional relationship between the vehicle V and the nearby vehicle. The situation information image C3 is displayed on the second image PC regardless of the presence or absence of a nearby vehicle and the display of the nearby vehicle image C4, but the display contents change according to the distance between the nearby vehicle and the vehicle V. The display control unit 44 makes the display contents of the situation information image C3 different between a first situation where a nearby vehicle on the side of the vehicle V is at a position close to the vehicle V and a second situation where a nearby vehicle on the side of the vehicle V is at a position farther from the vehicle V than the first situation. In the present embodiment, the first situation refers to a situation where the distance between the nearby vehicle and the vehicle V is within a predetermined distance range, and the second situation refers to a situation where the distance between the nearby vehicle and the vehicle V is outside the predetermined distance range. The display control unit 44 makes the display contents of the situation information image C3 different between a first situation where a nearby vehicle on the side of the vehicle V is at a position close to the vehicle V and a second situation where a nearby vehicle on the side of the vehicle V is at a position farther from the vehicle V than the first situation. In the present embodiment, the first situation refers to a situation where the distance between the nearby vehicle and the vehicle V is within a predetermined distance range, and the second situation refers to a situation where the distance between the nearby vehicle and the vehicle V is outside the predetermined distance range. In the present embodiment, the first situation refers to a situation where the distance between the nearby vehicle and the vehicle V is within a predetermined distance range, and the second situation refers to a situation where the distance between the nearby vehicle and the vehicle V is outside the predetermined distance range. In the present embodiment, the first situation refers to a situation where the distance between the nearby vehicle and the vehicle V is within a predetermined distance range, and the second situation refers to a situation where the distance between the nearby vehicle and the vehicle V is outside the 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 a neighboring vehicle approaches and then overtakes vehicle V and moves away forward An example of the second image PC is shown. FIG. 8 shows a neighboring vehicle in a lane on one side of vehicle V and shows the state of being located behind vehicle V. Since the display control unit 44 does not display neighboring vehicles within the area behind vehicle V, the neighboring vehicle image C4 is not displayed in the second image PC shown in FIG. 8. Also, in the example of FIG. 8, neighboring vehicles on one side of vehicle V are located outside the predetermined distance range in the area behind vehicle V. Therefore, the situation information image C3a shown in FIG. 8 is displayed in the second mode. Also, since there are no vehicles located within the predetermined distance range on the other side of vehicle V either, the situation information image C3b shown in FIG. 8 is also displayed in the second mode.

[0054] FIG. 9 shows the state where a neighboring vehicle in a lane on one side of vehicle V has approached vehicle V more closely than in FIG. 8 and reached within the predetermined distance range. Also in FIG. 9, since the neighboring vehicle is behind vehicle V, the neighboring vehicle image C4 is not displayed. On the other hand, this neighboring vehicle is located within the predetermined distance range in the area behind vehicle V. Therefore, the situation information image C3a shown in FIG. 9 is displayed in the first mode. Thus, in the second image PC, when a vehicle is approaching, the situation information image C3a on that vehicle side is displayed in the first mode, so that the occupant can recognize that a vehicle is approaching.

[0055] FIG. 10 shows the state where a neighboring vehicle in a lane on one side of vehicle V has overtaken vehicle V. That is, FIG. 10 shows an example where a neighboring vehicle exists in the area in front of vehicle V and on one side of vehicle V ​​​​​​​​​​ Since it is located within the display distance range from both Vs, as the adjacent vehicle image C4, it is displayed on the side lane image C2a on one side. In addition, since this adjacent vehicle is located within a predetermined distance range from the vehicle V, the situation information image C3a is displayed in the first mode.

[0056] FIG. 11 shows a state where an adjacent vehicle in a lane on one side of the vehicle V is farther from the vehicle V than in the state of FIG. 10. Also in FIG. 11, since this adjacent vehicle is located within a predetermined distance range from the vehicle V, the situation information image C3a is displayed in the first mode. Also in FIG. 11, since this adjacent vehicle is located within the display distance range from the vehicle V, it is displayed as the adjacent vehicle image C4. However, in the present embodiment, the display control unit 44 changes the display content of the adjacent vehicle image C4 according to the distance between the adjacent vehicle and the vehicle V. Here in, the display control unit 44 increases the transparency of the adjacent vehicle image C4 as the adjacent vehicle moves away from the vehicle V. That is, the closer the adjacent vehicle is to the vehicle V, the more opaque the adjacent vehicle image C4 becomes and the easier it is to be visually recognized, and the farther the adjacent vehicle is from the vehicle V, the more transparent the adjacent vehicle image C4 becomes and the more difficult it is to be visually recognized. Then, when the distance between the adjacent vehicle and the vehicle V becomes longer than the display distance range, the display control unit 44 maximizes the transparency of the adjacent vehicle image C4 and makes the adjacent vehicle image C4 not displayed. In FIG. 11, the adjacent vehicle is farther from the vehicle V than in the state of FIG. 10, but this adjacent vehicle is located within the display distance range. Therefore, the adjacent vehicle image C4 in FIG. 11 has a higher transparency than the adjacent vehicle image C4 in FIG. 10, but is not completely transparent and is displayed semi-transparently.

[0057] When the neighboring vehicle in the lane on one side of the vehicle V is further away from the vehicle V than in FIG. 11 the second image PC is displayed as shown in FIG. 8. That is, in this case, since the neighboring vehicle is located outside the predetermined distance range from the vehicle V on the front side of the vehicle V, the situation information image C3a is switched from the first mode to the second mode and displayed. Also, in this case, since the neighboring vehicle is located outside the display distance range from the vehicle V on the front side in the traveling direction D of the vehicle V, the neighboring vehicle image C 4 becomes completely transparent and is not displayed.

[0058] If the length from the end C3S to the end C3T of the situation information image C3 is defined as the wall length, the wall length may be arbitrarily set. For example, it may be the same length as the display distance at which the neighboring vehicle image C4 is displayed. In this case, when the neighboring vehicle in front of the vehicle V moves to the front side of the end C3T, the neighboring vehicle image C4 of that neighboring vehicle becomes non-displayed, and the situation information image C3 switches from the first mode to the second mode.

[0059] In the description from FIG. 8 to FIG. 11, an example of the change in the second image PC when there is a neighboring vehicle on the side of the vehicle V was shown. On the other hand, FIG. 12 shows an example of the second image PC when there is a neighboring vehicle in the same lane as the vehicle V. Even when there is a neighboring vehicle in the same lane as the vehicle V, the change in the display content of the neighboring vehicle image C4 is the same as the change shown in FIGS. 8 to 11. That is, the neighboring vehicle image C4 displays the neighboring vehicle within the display distance range in the front region of the vehicle V, and the transparency increases as it moves away from the vehicle V. On the other hand, when there is a neighboring vehicle in the same lane as the vehicle V, instead of the side situation information image C3, the display content of the side CL changes. That is, the neighboring vehicle image C4 displays the neighboring vehicle within the display distance range in the front region of the vehicle V, and the transparency increases as it moves away from the vehicle V. On the other hand, when there is a neighboring vehicle in the same lane as the vehicle V, instead of the side situation information image C3, the display content of the side CL changes. That is, ​​​​​​​That is, when a neighboring vehicle in the same lane as the vehicle V is within a predetermined distance range, the side CL is displayed in the first mode, and when a neighboring vehicle in the same lane as the vehicle V is outside the predetermined distance range, the side CL is displayed in the second mode. The first mode and the second mode of the side CL may be any display modes as long as the display contents are different. In this embodiment, however, the display control unit 44 makes the colors different between the first mode and the second mode. For example, the display control unit 44 may make the side CL in the first mode red and the side CL in the second mode blue.

[0060] FIG. 12 shows an example in the case where a neighboring vehicle in the same lane as the vehicle V and in front of it is within the predetermined distance range. In this case, the sides CLa and CLb are displayed in the first mode. Also, since a neighboring vehicle in the same lane as the vehicle V and in front of it is within the display distance range, a neighboring vehicle image C4 is displayed on the own lane C1 image. In this case, the neighboring vehicle image C4 may have different display contents such as lighting. Also, when a neighboring vehicle in the same lane as the vehicle V and in front of it is outside the predetermined distance range, for example, as shown in FIG. 8, the sides CL a and CLb are displayed in the second mode.

[0061] In this way, the display content of the side CL changes according to the distance between the neighboring vehicle in the same lane as the vehicle V and the vehicle V. That is, it can be said that the situation information image C3 is a situation information image showing the situation of neighboring vehicles on the side of the vehicle V, and the side CL is a situation information image showing the situation of neighboring vehicles in the same lane as the vehicle V.

[0062] The display control unit 44 causes the second image PC to be displayed on the display unit 22 in this way.

[0062] The display control unit 44 causes the second image PC to be displayed on the display unit 22 in this way. However, as described above, The second image PC described is just an example, and the display content of the second image PC is not limited to the above description.

[0063] As described above, the display control unit 44 switches and displays the manual driving image PA, the first image PB, and the second image PC according to the switching information. The display control unit 44 preferably switches seamlessly between the manual driving 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 A in the manual driving mode, and displays the first image PB and the second image PC in the automatic driving mode. However, the driving mode when displaying the manual driving image PA, the first image PB, and the second image PC is not limited to this. For example, in the manual driving mode, the manual driving image PA, the first image PB , and the second image PC may be switched and displayed, or in the automatic driving mode, the manual driving image PA, the first image PB, and the second image PC may be switched and displayed. Also, the vehicle V is not limited to being a vehicle capable of switching between the manual driving mode and the automatic driving mode. For example, it may be a vehicle that cannot perform automatic driving. In the case of such a vehicle, the determination as to whether it is in the first state or the second state may be based not on the degree of anxiety of the occupant towards automatic driving, but on the degree to which the occupant wants to grasp the surrounding situation.

[0064] Also, 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 and may not be provided in the vehicle V, but may be provided outside the vehicle V. In this case, the display unit 2 2 receives an image from the control unit 30 outside the vehicle V by communication and displays it. Also, At least a part of the vehicle information acquisition unit 40, the switching information acquisition unit 42, and the display control unit 44 of the control unit 30 may not be provided in the vehicle V.

[0065] Next, the image switching flow by the display device 10 will be described based on the flowchart. FIG. 13 is a flowchart for explaining the image switching flow according to the present 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 acquires, as switching information, driving mode information indicating whether the vehicle V is in the manual driving mode or the automatic driving mode, and driving situation information indicating whether the vehicle V is in the first state or the second state. The control unit 30 determines whether the vehicle V is in the manual driving mode or the automatic driving mode based on the switching information (step S12). If it is in the manual driving mode (step S12; Yes), the display control unit 44 causes the manual driving image PA to be displayed on the display unit 22 (step S14). In step S14, for example, if the first image PB or the second image PC is currently being displayed, the display control unit 44 seamlessly switches the display content of the image P from the first image PB or the second image PC to the manual driving image PA. On the other hand, if it is not in the manual driving mode (step S12; No), that is, if it is in the automatic driving mode, the control unit 30 determines whether the vehicle V is in the first state or the second state based on the switching information (step S16). If it is in the first state (step S16; Yes), the control unit 30 causes the first image PB to be displayed on the display unit 22 by the display control unit 44 (step S18). In step S18, for example, if the manual driving image PA or the second image PC is currently being displayed,

[0066] When causing the display, the display control unit 44 seamlessly switches the display content of the image P from the current manual driving image PA or the second image PC to the first image PB. On the other hand, when not in the first state (step S16; No), that is, when in the second state, the control unit 30 causes the display control unit 4 4 to display the second image PC on the display unit 22 (step S20). In step S20 , for example, when the current manual driving image PA or the first image PB is being displayed, the display control unit 44 seamlessly switches the display content of the image P from the current manual driving image PA or the first image PB to the second image PC. After executing steps S14, S18, and S20, the process proceeds to step S15. If it is determined to end the process (step S15; Yes), this process ends, and if not (step S15; No), the process returns to step S10 and continues.

The display control unit 44 switches between and displays a first image PB that displays the neighboring vehicle and a second image PC that displays the neighboring vehicle in a state where the amount of information is less than that of the first image PB. Here, when displaying information on a neighboring vehicle on the display unit 22 mounted on the vehicle V, it is required to appropriately display the information on the neighboring vehicle according to the situation of the vehicle V. In contrast, the control unit 30 according to the present embodiment switches between and displays a first image PB that displays the neighboring vehicle and a second image PC that displays the neighboring vehicle in a state where the amount of information is less than that of the first image PB.

Therefore, the control unit 30 according to the present embodiment According to this, it is possible to switch between the first image PB and the second image PC according to the situation of the vehicle V, and it is possible to vary the amount of information on the neighboring vehicles provided to the occupant according to the situation of the vehicle V. Therefore, according to the control unit 30 according to this embodiment, it is possible to appropriately display the information on the neighboring vehicles according to the situation of the vehicle V. Furthermore, for example, when the vehicle V is traveling in the automatic driving mode, there are cases where the situation of the vehicle V changes, such as when the occupant may feel uneasy about the automatic driving or may feel less uneasy. For example, when feeling uneasy about the automatic driving, the occupant tends to want to obtain more information on the neighboring vehicles even in the automatic driving mode. On the other hand, when not feeling uneasy about the automatic driving, the occupant tends to think that there is no need to obtain so much information on the neighboring vehicles. Since the control unit 30 according to the embodiment can switch between the first image PB and the second image PC, for example, when the occupant feels uneasy about the automatic driving, the first image PB is displayed to provide more information on the neighboring vehicles, and when the occupant does not feel uneasy about the automatic driving, the second image PC is displayed to reduce the amount of information on the neighboring vehicles. Therefore, according to the control unit 30 according to this embodiment, it is particularly effective for the vehicle V performing automatic driving. In addition, the display control unit 44 causes the second image PC to be displayed such that the number of neighboring vehicles displayed in the second image PC is less than the number of neighboring vehicles displayed when the first image PB is displayed when the vehicle V is in the same situation. According to the control unit 30 according to this embodiment, since it is possible to change the number of neighboring vehicles to be displayed according to the situation of the vehicle V, according to the situation of the vehicle V, it is possible to change the number of neighboring vehicles to be displayed.

[0068] Moreover, for example, when the vehicle V is traveling in the automatic driving mode, there are cases where the situation of the vehicle V changes, such as when the occupant may feel uneasy about the automatic driving or may feel less uneasy. For example, when feeling uneasy about the automatic driving, the occupant tends to want to obtain more information on the neighboring vehicles even in the automatic driving mode.
