[0004] It is possible to control the display so that the hazard map image is always superimposed on the map image, but in this case, the occupants who look at the display are likely to find it annoying.

[0005] In consideration of the above, the present invention aims to provide a vehicle display device, a vehicle, a vehicle display system, a vehicle display method, and a program that can display hazard map images in a way that makes it less annoying for occupants looking at the display. [Means for solving the problem]

[0006] The vehicle display device according to claim 1 includes a display mounted on a vehicle and a processor that controls the display, wherein the processor: It is determined to have occurred when at least one of the following conditions 1 and 2 is met: When a specific event occurs, the display is brought into a state in which a hazard map image showing a hazard map of a predetermined area can be displayed. Condition 1: The current date is Disaster Prevention Day (September 1st) designated by the country in which the vehicle is located. Condition 2: The current date is a disaster prevention event day designated by the local government in the area where the vehicle is located.

[0007] The processor of the vehicle display device according to claim 1 comprises: It is determined to have occurred when at least one of conditions 1 and 2 is met. When a specific event occurs, the display is set to a state where it can display a hazard map image showing a hazard map of a specified area. If hazard map images were frequently displayed on the display regardless of the occurrence of a specific event, occupants looking at the display would likely feel annoyed. In contrast, the vehicle display device described in claim 1 sets the display to a state where it can display a hazard map image showing a hazard map of a specified area when a specific event occurs. Therefore, occupants looking at the display are less likely to feel annoyed.

[0008] The vehicle display device according to the invention of claim 2 is the display device of claim 1, wherein the vehicle includes a receiver capable of receiving information relating to the hazard map image from an external communication device via wireless communication.

[0009] In the invention described in claim 2, the vehicle is provided with a receiver capable of receiving information related to the hazard map image from an external communication device via wireless communication, so there is no need for the vehicle to be provided with a recording device for recording information related to the hazard map image.

[0010] The vehicle display device according to the invention recited in claim 3 is the invention recited in claim 1 or claim 2, wherein the hazard map image is a hazard map image of an area including the current position of the vehicle.

[0011] In the invention described in claim 3, the hazard map image is a hazard map image of an area including the current location of the vehicle. When a hazard map image of an area including the current location of the vehicle is displayed on the display regardless of the occupant's intention, the occupant is less likely to feel annoyed when looking at the display than when a hazard map image of an area not including the current location of the vehicle is displayed on the display regardless of the occupant's intention.

[0014] Claim 4In the invention described in claim 1 or claim 2, the vehicle display device according to the present invention is characterized in that, when a selection operation to select at least one display area from a plurality of areas is performed on a first operating device provided on the vehicle, the processor causes the display to display the hazard map image relating to the display area.

[0015] Claim 4 In the invention described in (1), when a selection operation is performed on a first operating device provided in a vehicle, a hazard map image for a display area that is a selected area from a plurality of areas is displayed on the display. When a hazard map image for a display area selected by the occupant's own will is displayed on the display in this way, the occupant is less likely to feel annoyed when looking at the display than when a hazard map image for a area selected regardless of the occupant's will is displayed on the display.

[0016] Claim 5 The vehicle display device according to the invention described in Claims 1 to 4 In any one of the inventions described above, when the specific event occurs, the processor causes an alarm device to notify an occupant of the vehicle of information urging the occupant to perform a display operation on a second operating device provided in the vehicle, and when the occupant performs the display operation on the second operating device, causes the display to display the hazard map image.

[0017] Claim 5 In the invention described in (1), when a specific event occurs, an alarm device issues information prompting an occupant to perform a display operation on a second operating device provided in the vehicle. When the occupant performs a display operation on the second operating device, a hazard map image is displayed on the display. In this way, when the hazard map image is displayed on the display when the occupant performs a display operation of their own volition, the occupant is less likely to feel annoyed when looking at the display than when the hazard map image is displayed on the display regardless of the occupant's will.

[0020] Claim 6 The vehicle according to the invention described in Claims 1 to 5 The vehicle display device according to any one of the above items is provided.

[0021] Claim 7 The vehicle display system according to the invention described in Claim 6 and an external communication device capable of wirelessly transmitting information relating to the hazard map image to a receiver provided in the vehicle.

[0022] Claim 8 The vehicle display method according to the invention described above includes: It is determined to have occurred when at least one of the following conditions 1 and 2 is met: When a specific event occurs, a display mounted on the vehicle is brought into a state in which a hazard map image showing a hazard map of a predetermined area can be displayed. Condition 1: The current date is Disaster Prevention Day (September 1st) designated by the country in which the vehicle is located. Condition 2: The current date is a disaster prevention event day designated by the local government in the area where the vehicle is located.

[0023] Claim 9 The program according to the invention described in It is determined to have occurred when at least one of the following conditions 1 and 2 is met: When a specific event occurs, the processor executes a process to make the display mounted on the vehicle capable of displaying a hazard map image showing a hazard map of a predetermined area. Condition 1: The current date is Disaster Prevention Day (September 1st) designated by the country in which the vehicle is located. Condition 2: The current date is a disaster prevention event day designated by the local government in the area where the vehicle is located. [Effects of the Invention]

[0024] As described above, the vehicle display device, vehicle, vehicle display system, vehicle display method, and program of the present invention have the excellent effect of being able to display hazard map images in a way that does not cause annoyance to occupants looking at the display.

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle display device, a vehicle, a vehicle display system, a vehicle display method, and a program according to the present invention will be described with reference to the drawings.

[0027] As shown in FIG. 1, the vehicular display system 10 of this embodiment includes a vehicle 20 and an external server (external communication device) 30.

[0028] 1, a vehicle 20 capable of data communication with an external server 30 via a network (e.g., the Internet) has an ECU (Electronic Control Unit) 21, a display (first operating device, second operating device) (alarm device) 22 having a touch panel, a speaker (alarm device) 23, an IG-SW (ignition switch) 24, and a GPS (Global Positioning System) receiver 25. A vehicle ID is assigned to the vehicle 20. The display 22, the speaker 23, the IG-SW 24, and the GPS receiver 25 are connected to the ECU 21. The ECU 21 and the display 22 are components of a vehicle display device 15.

[0029] As will be described later, the display 22 can display various images. The speaker 23 can output various sounds. The GPS receiver 25 receives GPS signals transmitted from GPS satellites to obtain information regarding the location where the vehicle 20 is traveling (hereinafter referred to as "location information"). When the IG-SW 24 is in the off state, the drive source of the vehicle 20 is disabled, and when the IG-SW 24 is in the on state, the drive source is enabled. Note that the drive source includes, for example, at least one of an engine and an electric motor. Therefore, the term "IG-SW" in this specification includes an ignition switch operated by a key and other switches. Other switches include, for example, a push-button start button.

[0030] 2, the ECU 21 includes a CPU (Central Processing Unit) (processor) 21A, a ROM (Read Only Memory) 21B, a RAM (Random Access Memory) 21C, a storage 21D, a wireless communication I / F (Interface) (receiver) 21E, an internal communication I / F 21F, and an input / output I / F 21G. The CPU 21A, the ROM 21B, the RAM 21C, the storage 21D, the wireless communication I / F 21E, the internal communication I / F 21F, and the input / output I / F 21G are connected to each other via an internal bus 21Z so as to be able to communicate with each other. The ECU 21 can acquire information related to time from a timer. The ECU 21 (input / output I / F 21G) is connected to a display 22, a speaker 23, an IG-SW 24, and a GPS receiver 25.

[0031] The CPU 21A is a central processing unit that executes various programs and controls each part. The CPU 21A reads programs from the ROM 21B or the storage 21D and executes the programs using the RAM 21C as a work area. The CPU 21A controls each component and performs various arithmetic processing in accordance with the programs recorded in the ROM 21B or the storage 21D.

[0032] The ROM 21B stores various programs and various data. The RAM 21C temporarily stores programs or data as a working area. The storage 21D is configured with a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs and various data. For example, the storage 21D stores map data of the entire country in which the vehicle 20 is located.

[0033] The wireless communication I / F 21E is an interface for wireless communication with various devices. For example, the wireless communication I / F 21E is capable of wireless communication with an external server 30. The wireless communication I / F 21E uses communication standards such as Bluetooth (registered trademark) and Wi-Fi (registered trademark).

[0034] The internal communication I / F 21F is an interface for connecting to an ECU other than the ECU 21 provided in the vehicle 20 via an external bus.

[0035] The input / output I / F 21G is an interface for communicating with the display 22, the speaker 23, the IG-SW 24, and the GPS receiver 25.

[0036] 3 is a block diagram showing an example of the functional configuration of the ECU 21. The ECU 21 has, as its functional configuration, a display control unit 211, a speaker control unit 212, an operation determination unit 213, and a transmission / reception control unit 214. The display control unit 211, the speaker control unit 212, the operation determination unit 213, and the transmission / reception control unit 214 are realized by the CPU 21A reading and executing programs stored in the ROM 21B.

[0037] The display control unit 211 controls the display 22. Multiple applications (programs) are installed in the ECU 21. Therefore, as shown in FIG. 6, when the display 22 is in the on state, the display control unit 211 can cause the display 22 to display a main image (initial image) 22MD including application images (hereinafter referred to as AP images) 22AP1, 22AP2, 22AP3, . . . 22AP8 representing eight applications. The AP image 22AP1 is an image representing a navigation application. In other words, the vehicle 20 is equipped with a navigation system. The AP image 22AP2 is an image representing a music application. As will be described further below, the display control unit 211 causes the display 22 to display various images including a map image and a hazard map image.

[0038] The speaker control unit 212 controls the speaker 23 .

[0039] As will be described later, the operation determination unit 213 performs various processes in response to touch operations by the occupant's hand on various operation images displayed on the display 22 (touch panel).

[0040] The transmission / reception control unit 214 controls the wireless communication I / F 21E and the internal communication I / F 21F. As will be described later, the transmission / reception control unit 214, for example, wirelessly transmits various pieces of information to the external server 30 via the wireless communication I / F 21E, and causes the wireless communication I / F 21E to receive various pieces of information wirelessly transmitted from the external server 30.

[0041] 2, the external server 30 shown in Fig. 1 includes, as a hardware configuration, a CPU (processor) 30A, a ROM 30B, a RAM 30C, a storage 30D, a wireless communication I / F 30E, an internal communication I / F 30F, and an input / output I / F 30G. The CPU 30A, ROM 30B, RAM 30C, storage 30D, wireless communication I / F 30E, internal communication I / F 30F, and input / output I / F 30G are connected to each other via an internal bus 30Z so as to be able to communicate with each other. The ECU 30 can obtain information related to the time from a timer.

[0042] Data relating to a hazard map of the entire country in which the vehicle 20 is located is recorded in the ROM 30B or storage 30D of the external server 30. When a new disaster occurs in the country in which the vehicle 20 is located, the contents of the data relating to the hazard map are updated as necessary. Note that disasters defined in the hazard map of this embodiment and in a specific event determination map 35 (described later) include, for example, earthquakes, landslides, floods, and tsunamis.

[0043] 4 is a block diagram showing an example of the functional configuration of the hardware of the external server 30. The hardware of the external server 30 has, as its functional configuration, a condition determination unit 301 and a transmission / reception control unit 302. The condition determination unit 301 and the transmission / reception control unit 302 are realized by the CPU 30A reading and executing a program stored in the ROM 30B.

[0044] As will be described later, the condition determination unit 301 determines whether various conditions are satisfied. For example, the condition determination unit 301 determines whether at least one of conditions 1 to 3 defined in a specific event determination map 35 (see FIG. 5) recorded in the ROM 30B is satisfied. When the condition determination unit 301 determines that at least one of conditions 1 to 3 is satisfied, the condition determination unit 301 determines that a specific event has occurred.

[0045] Condition 1 is met when the current date recognized by condition determination unit 301 based on the timer is a nationally designated disaster prevention day (September 1st) or a date one year or multiple years after the date of the first major disaster. A first major disaster is a disaster that has occurred in the country in which vehicle 20 is located and caused particularly severe damage to any region.

[0046] Condition 2 is met when the current date recognized by condition determination unit 301 based on the timer is the day of a disaster prevention event designated by the local government of the area where vehicle 20 is located, or when the current time is within 24 hours of the occurrence of a second major disaster that occurred in the country where vehicle 20 is located. The second major disaster is a disaster that occurred in the country where vehicle 20 is located and caused major damage to some area, but is different from the first major disaster.

[0047] Condition 3 is met when the current date recognized by the condition determination unit 301 based on the timer is one year or more than one year after the date of the specific region disaster. A specific region disaster is a disaster that has occurred in the region where the vehicle 20 is located and has caused significant damage to the region.

[0048] When a new disaster occurs in the country in which the vehicle 20 is located, the contents of the specific event determination map 35 are updated as necessary.

[0049] The transmission / reception control unit 302 controls the wireless communication I / F 30E and the internal communication I / F 30F. As will be described later, the transmission / reception control unit 302, for example, wirelessly transmits various pieces of information to the vehicle 20 via the wireless communication I / F 30E, and causes the wireless communication I / F 30E to receive various pieces of information wirelessly transmitted from the vehicle 20.

[0050] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0051] First, the flow of processing performed by the external server 30 will be described using the flowchart in Fig. 10. The external server 30 repeatedly executes the processing of the flowchart in Fig. 10 every time a predetermined time period has elapsed.

[0052] First, in step S10, the condition determination unit 301 of the external server 30 determines whether or not information indicating that the IG-SW 24 is in the ON state and the ID information of the vehicle 20 have been received from the vehicle 20.

[0053] If the external server 30 determines "Yes" in step S10, the process proceeds to step S11, where the condition determination unit 301 determines whether or not at least one of conditions 1 to 3 is met.

[0054] If the external server 30 determines "Yes" in step S11, the process proceeds to step S12, where the wireless communication I / F 30E controlled by the transmission / reception control unit 302 wirelessly transmits a notification signal together with the ID information of the vehicle 20 to the vehicle 20.

[0055] After completing the process of step S12, the external server 30 proceeds to step S13 and determines whether or not it has received regional information, which will be described later, from the vehicle 20.

[0056] If the external server 30 judges Yes in step S13, it proceeds to step S14, and the wireless communication I / F 30E controlled by the transmission / reception control unit 302 wirelessly transmits to the vehicle 20 data regarding a hazard map of the area corresponding to the area information judged Yes in step S13.

[0057] When the process of step S14 is completed or when the determinations in steps S10 and S11 are No, the external server 30 temporarily ends the process of the flowchart in FIG.

[0058] Next, the flow of processing performed by the ECU 21 will be described with reference to the flowchart of Fig. 11. The ECU 21 repeatedly executes the processing of the flowchart of Fig. 11 every time a predetermined time elapses.

[0059] First, in step S20, the transmission / reception control unit 214 of the ECU 21 determines whether the IG-SW 24 is in the ON state.

[0060] If the ECU 21 judges Yes in step S20, it proceeds to step S21, and the wireless communication I / F 21E controlled by the transmission / reception control unit 214 wirelessly transmits to the external server 30 information indicating that the IG-SW 24 is in the on state and the ID information of the vehicle 20.

[0061] After completing the process of step S21, the ECU 21 proceeds to step S22, where the display control unit 211 causes the display 22 to display the main image 22MD shown in FIG.

[0062] After completing the process of step S22, the ECU 21 proceeds to step S23 and determines whether or not the AP images 22AP1, 22AP2, 22AP3, . . . , 22AP8 have been touched by the occupant (by their hands).

[0063] If the ECU 21 determines "Yes" in step S23, the ECU 21 proceeds to step S24. At this time, the ECU 21 launches an application corresponding to the touch-operated AP images 22AP1, 22AP2, 22AP3, . . . 22AP8. For example, when the occupant touches the AP image 22AP2, the display 22 controlled by the display control unit 211 displays an initial screen 22AP2Im, as shown in FIG. 8. Note that the initial screen 22AP2Im shown in FIG. 8 includes a notification image 27A, a Yes button image 28A, and a No button image 28B, but the initial screen 22AP2Im when the processing of step S24 is executed does not include the notification image 27A, the Yes button image 28A, and the No button image 28B. When the occupant touches an image included in the initial screen 22AP2Im with their hand, the speaker 23 controlled by the speaker control unit 212 outputs the music selected by the touch operation.

[0064] Furthermore, when the occupant touches the AP image 22AP1 in step S23, the display 22 controlled by the display control unit 211 displays a map image 22AP1Im, as shown in Fig. 9. Note that the map image 22AP1Im shown in Fig. 9 includes the notification image 27B, the Yes button image 28A, and the No button image 28B, but the map image 22AP1Im when the processing of step S24 is executed does not include the notification image 27B, the Yes button image 28A, or the No button image 28B. This map image 22AP1Im includes an image representing an area including the current position of the vehicle 20 identified by the ECU 21 based on the position information of the vehicle 20. The map image 22AP1Im shown in Fig. 9 includes, for example, an image 22Im1 representing the sea, an image 22Im2 representing a river, an image 22Im3 representing a mountain, and an image 22Im4 representing a road. Furthermore, the road image 22Im4 includes a road image 22Im4-1 representing a substantially straight road near a mountain (image 22Im3), a road image 22Im4-2 representing a substantially straight road along the coast, a road image 22Im4-3 representing a substantially straight road along a river (image 22Im2), and a road image 22Im4-4 representing a road substantially parallel to this road (road image 22Im4-3). Note that the circle (◯) indicated by the symbol 20rp in FIG. 9 indicates the current position of the vehicle 20 based on the position information of the vehicle 20. The virtual line indicated by the symbol Rt is the driving route set using the navigation system, and the star (☆) indicated by the symbol 20gl is the destination of the vehicle 20.

[0065] After completing the process of step S24, the ECU 21 proceeds to step S25, where the transmission / reception control unit 214 determines whether the wireless communication I / F 21E has received a notification signal from the external server 30.

[0066] If the ECU 21 determines "Yes" in step S25, the ECU 21 proceeds to step S26, where the display control unit 211 displays the notification images 27A, 27B, 27C, the Yes button image 28A, and the No button image 28B on the display 22. For example, if the main image 22MD is displayed on the display 22 at the time of processing step S25, the notification image 27C, the Yes button image 28A, and the No button image 28B are displayed superimposed on the main image 22MD, as shown in FIG. 7. The notification image 27C includes a text image that reads "Do you want to display a hazard map?" The same text image is also included in the notification images 27A and 27B. Furthermore, if the initial screen 22AP2Im is displayed on the display 22 at the time of processing step S25, the notification image 27A, the Yes button image 28A, and the No button image 28B are displayed superimposed on the initial screen 22AP2Im, as shown in FIG. 8. Furthermore, if the map image 22AP1Im is being displayed on the display 22 at the time of processing step S25, as shown in FIG. 9, the notification image 27B, the Yes button image 28A, and the No button image 28B are displayed superimposed on the map image 22AP1Im.

[0067] After completing the process of step S26, the ECU 21 proceeds to step S27, where the operation determination unit 213 determines whether or not the Yes button image 28A has been touched by the occupant.

[0068] If the ECU 21 determines "Yes" in step S27, the ECU 21 proceeds to step S28. In this case, the area selection button image 29 is displayed on the display 22. For example, if the map image 22AP1Im is displayed on the display 22 at the time of processing in step S28, the area selection button image 29 is displayed superimposed on the map image 22AP1Im, as shown in Fig. 12. The area selection button image 29 includes a first selection button image 29A, a second selection button image 29B, a third selection button image 29C, a fourth selection button image 29D, a fifth selection button image 29E, a sixth selection button image 29F, and a seventh selection button image 29G. When the occupant performs a touch operation (display operation) on any of the first selection button image 29A, the second selection button image 29B, the third selection button image 29C, the fourth selection button image 29D, the fifth selection button image 29E, the sixth selection button image 29F, and the seventh selection button image 29G, the operation determination unit 213 determines Yes in step S28. Note that when the first selection button image 29A is touched, a region including the current location of the vehicle 20 is selected as the display region. On the other hand, when any of the second selection button image 29B, the third selection button image 29C, the fourth selection button image 29D, the fifth selection button image 29E, the sixth selection button image 29F, and the seventh selection button image 29G is touched, a remote region distant from the current location of the vehicle 20 is selected as the display region. The distance from the current location of the vehicle 20 to each remote region may be any distance. For example, the distance from the current location of the vehicle 20 to the remote area corresponding to the second selection button image 29B may be 100 km, and the distance from the current location of the vehicle 20 to the remote area corresponding to the third selection button image 29C may be 300 km.

[0069] If the ECU 21 determines "Yes" in step S28, the ECU 21 proceeds to step S29, where the wireless communication I / F 21E controlled by the transmission / reception control unit 214 wirelessly transmits to the external server 30 regional information relating to the selected display region.

[0070] After completing the process of step S29, the ECU 21 proceeds to step S30, where the transmission / reception control unit 214 determines whether the wireless communication I / F 21E has received data relating to a hazard map of the area corresponding to the area information from the external server 30.

[0071] If the ECU 21 determines "Yes" in step S30, the process proceeds to step S31, where the display 22 controlled by the display control unit 211 displays the hazard map image 26, as shown in FIG. 13. Assume now that the occupant touches the first selection button image 29A in step S28. In this case, as shown in FIG. 13, the hazard map image 26 includes a first warning image 26A, a second warning image 26B, and a third warning image 26C. The first warning image 26A indicates that a landslide has occurred in this area in the past. The second warning image 26B indicates that a flood (river overflow) has occurred in this area in the past. The third warning image 26C indicates that a tsunami has occurred in this area in the past.

[0072] For example, if the occupant touches any of the second selection button image 29B, the third selection button image 29C, the fourth selection button image 29D, the fifth selection button image 29E, the sixth selection button image 29F, and the seventh selection button image 29G in step S28, a map image of the selected remote area (display area) is displayed on the display 22, and a hazard map image of the remote area transmitted from the external server 30 is displayed superimposed on this map image.

[0073] After completing the process of step S31, the ECU 21 proceeds to step S32, where it determines, based on the information obtained from the timer, whether a predetermined display time has elapsed since the time when the display of the hazard map image 26 started. This display time is, for example, 15 minutes. However, the display time may be a length other than 15 minutes.

[0074] If the ECU 21 determines "Yes" in step S32, the process proceeds to step S33, where the display control unit 211 erases the hazard map image 26 from the display 22.

[0075] If the ECU 21 determines No in step S27, the process proceeds to step S34. When the occupant performs a touch operation on the No button image 28B, the ECU 21 determines Yes in step S34. In this case, the area selection button image 29 is not displayed on the display 22. That is, in this case, the display 22 does not display the hazard map image 26.

[0076] When the determinations in steps S20 and S25 are No, when the determination in step S34 is Yes, or when the processing of step S33 is completed, the ECU 21 temporarily ends the processing of the flowchart in FIG.

[0077] As described above, the vehicle display device, vehicle, vehicle display system, vehicle display method, and program of the present embodiment make it possible to display a hazard map image 26 of a predetermined area on the display 22 when a specific event occurs. If the hazard map image 26 were frequently displayed on the display 22 regardless of the occurrence of a specific event, the occupant would likely feel annoyed when looking at the display 22. As a result, the occupant's attention when recognizing the hazard map image 26 is likely to be low. In contrast, if the hazard map image 26 is displayed on the display 22 when a specific event occurs, as in the present embodiment, the occupant is less likely to feel annoyed when looking at the display 22. As a result, the occupant is more likely to recognizing the information in the hazard map image 26 with a high level of attention.

[0078] Furthermore, in this embodiment, when a specific event occurs, notification images 27A, 27B, and 27C are displayed on the display 22 to prompt the occupant to perform a touch operation on an operation screen (Yes button image 28A) displayed on the display 22 (touch panel) provided in the vehicle 20. When the occupant performs a touch operation on the operation screen (Yes button image 28A) displayed on the display 22 (touch panel), a hazard map image 26 is displayed on the display 22. In this way, when the hazard map image 26 is displayed on the display 22 when the occupant performs a touch operation of their own volition, the occupant is less likely to feel annoyed when looking at the display 22 than when the hazard map image 26 is displayed on the display 22 regardless of the occupant's intention.

[0079] Furthermore, in this embodiment, when a touch operation is performed on the display 22 (touch panel), a hazard map image 26A relating to a display area that is an area selected from a plurality of areas is displayed on the display 22. When the hazard map image 26A relating to the display area selected by the occupant's own will is displayed on the display 22 in this way, the occupant is less likely to feel annoyed when looking at the display 22 than when a hazard map image relating to an area selected regardless of the occupant's will is displayed on the display 22.

[0080] Furthermore, in this embodiment, a specific event occurs when a predetermined day, such as a disaster prevention day or a disaster prevention event day, or a first or second large-scale disaster occurrence day, arrives. When the hazard map image 26 is displayed on the display 22 on such a predetermined day, the occupants are unlikely to feel annoyed when they see the display 22.

[0081] Furthermore, consider a comparative example in which a specific event occurs when a specific time arrives on a specific day. In this comparative example, when the occupant uses the vehicle 20 at a time different from the specific time on the specific day (when the occupant is not using the vehicle 20 at the specific time), the occupant will be unable to view the hazard map image 26. In contrast, as in the present embodiment, if a specific event occurs when the IG-SW 24 is turned on at any time during the specific day, the occupant will be able to view the hazard map image 26 if the occupant turns on the IG-SW 24 at any time during the specific day.

[0082] Furthermore, in this embodiment, data relating to the hazard map is recorded in the ROM 30B or storage 30D of the external server 30. Therefore, the vehicle 20 does not need to be provided with a recording device that records information relating to the hazard map.

[0083] The above describes the vehicle display device, vehicle, vehicle display system, vehicle display method, and program according to the embodiments, but the design of the vehicle display device, vehicle, vehicle display system, vehicle display method, and program can be modified as appropriate within the scope that does not deviate from the gist of the present invention.

[0084] For example, when the vehicle 20 reaches the destination of the travel route, a specific event may occur regardless of whether conditions 1 to 3 are satisfied. If a hazard map image is displayed on the display 22 when the vehicle 20 reaches the destination, the occupants are less likely to feel annoyed when looking at the display 22 than if the hazard map image is displayed on the display 22 while the vehicle 20 is traveling.

[0085] For example, when a specific event occurs, the ECU 21 may control the display 22 to display a hazard map image on the display 22 regardless of the intention of the occupant.

[0086] Furthermore, when a specific event occurs while the display 22 is in the off state, the ECU 21 may control the display 22 to switch the display 22 to the on state regardless of the intention of the occupant. In this case, the ECU 21 may cause the display 22 to display the notification images 27A, 27B, 27C, the Yes button image 28A, and the No button image 28B, or may cause the display 22 to display a hazard map image of a predetermined area regardless of the intention of the occupant.

[0087] For example, when a specific event occurs, the speaker (alert device) 23 may output the information represented by the alert images 27A, 27B, and 27C. Furthermore, when a specific event occurs, the display (alert device) or speaker (alert device) of a mobile terminal (e.g., a smartphone) capable of wireless communication with the vehicle 20 may output the information represented by the alert images 27A, 27B, and 27C. Furthermore, when a specific event occurs, a hazard map image of a predetermined area may be displayed on the display of the mobile terminal regardless of the intention of the occupant.

[0088] The vehicle display system may be configured so that, when a hazard map image 26 is displayed on the display 22 and an occupant performs a predetermined operation on an input device (e.g., the touch panel) provided in the vehicle, the hazard map image 26 continues to be displayed on the display 22 even after the display time has elapsed.

[0089] Furthermore, the vehicle 20 may be equipped with a voice recognition device (first operating device, second operating device). In this case, the occupant gives voice instructions as to whether or not to display a hazard map image on the display 22 and as to which area to select as the display area. The voice recognition device recognizes this voice instruction, and the recognized instruction content is transmitted from the voice recognition device to the ECU 21.

[0090] For example, a hazard map image showing only a part of the surrounding area of ​​the travel route set by the navigation system and a hazard map image showing only a part of the surrounding area of ​​the destination may be displayed on the display 22. For example, a hazard map image (first warning image 26A) showing only a part of the surrounding area of ​​the travel route Rt displayed in Figures 9, 12, and 13 may be displayed on the display 22.

[0091] The ECU 21 of the vehicle 20 may have the function of the external server 30. In this case, data related to a hazard map of the entire country in which the vehicle 20 is located is recorded in the ROM 21B or storage 21D of the vehicle 20. In this case, the vehicle 20 constitutes a vehicle display system.

[0092] At least one of the recording devices of the vehicle 20 and the external server 30 may record data related to hazard maps for only part of the country in which the vehicle 20 is located. Also, at least one of the recording devices of the vehicle 20 and the external server 30 may record data related to hazard maps for a country other than the country in which the vehicle 20 is located.

[0093] The number of selection button images included in the region selection button image 29 may be a number other than seven.

[0094] The vehicular display system 10 may be configured so that the occupant can simultaneously touch and operate multiple selection button images included in the area selection button image 29. In this case, map images of the selected areas and hazard map images corresponding to each area are displayed on the display 22.

[0095] Instead of the GPS receiver 25, the vehicle 20 may be equipped with a receiver capable of receiving information from satellites of a global navigation satellite system other than GPS (for example, Galileo).

[0096] The ECU 21 may read map data from a web server and cause the display 22 to display a map image based on this map data. [Explanation of symbols]
