Description

Technical Field

[0001] This invention relates to an advertising display device for vehicles and a vehicle. Background Technology

[0002] Japanese Patent Application Publication No. 2020-67560 discloses an information processing device that acquires the driving conditions of a vehicle and determines the amount of information to be displayed in an advertisement based on the acquired driving conditions. Specifically, the information processing device described in Japanese Patent Application Publication No. 2020-67560 is configured to display a simple advertisement when the vehicle is traveling at a high speed and a complex advertisement when waiting at a traffic signal. Summary of the Invention

[0003] The problem that the invention aims to solve

[0004] However, in vehicles where advertising information is displayed on a display unit located on the outer surface of the vehicle body, power consumption increases as the advertising information is displayed. The information processing device described in Japanese Patent Application Publication No. 2020-67560 does not take into account the power consumption associated with displaying advertising information, leaving room for improvement in extending the vehicle's driving range.

[0005] The purpose of this invention is to provide a vehicle advertising display device and vehicle that can extend the driving range of a vehicle displaying advertisements.

[0006] Technical solutions for solving the problem

[0007] The vehicle advertising display device according to the first aspect of the present invention has a processor.

[0008] The processor is configured to display advertising information on a display unit located on the outer surface of the vehicle body, and to reduce the vehicle's power consumption based on the vehicle's status.

[0009] With this structure, advertising information can be displayed on a screen located on the outer surface of the vehicle body, allowing people around the vehicle to visually recognize the advertisements. Furthermore, since the processor reduces the vehicle's power consumption based on its status, the vehicle can travel for a longer period compared to structures that do not consider power consumption. Moreover, the term "vehicle status" here is not limited to the vehicle's own physical states such as speed, interior temperature, and fuel level, but broadly includes user-defined settings such as destination information. Additionally, "vehicle status" includes external forces acting on the vehicle, such as the number of occupants and the amount of cargo loaded.

[0010] According to the vehicle advertising display device of the first method described above, the processor reduces the power consumption related to the display of the advertising information when the vehicle speed, which is the vehicle state, is greater than a predetermined speed.

[0011] With this structure, when the vehicle speed exceeds a predetermined speed, the processor reduces power consumption related to the display of advertising information. At higher vehicle speeds, the advertising information may not be effectively displayed because people around the vehicle cannot see it. Therefore, by reducing power consumption related to the display of advertising information at higher vehicle speeds, the power used for displaying advertising information can be used for vehicle operation.

[0012] According to the vehicle advertising display device of the first method described above, the processor reduces power consumption related to the display of advertising information when the distance to the destination set as the vehicle state is greater than a predetermined distance.

[0013] With this structure, the processor reduces power consumption when the distance to the destination is greater than a predetermined distance. Therefore, it is possible to prevent fuel depletion before reaching the destination.

[0014] The vehicle involved in the second aspect of the present invention has:

[0015] The vehicle body has a display unit on its outer surface; and

[0016] The vehicle advertising display device according to any one of technical solutions 1 to 3.

[0017] According to this structure, the functions described in technical solutions 1 to 3 can be achieved in the vehicle.

[0018] According to the vehicles involved in the second method mentioned above, among which,

[0019] The vehicle body has multiple display units on its outer surface.

[0020] The processor temporarily stops displaying the advertising information on a portion of the multiple display units based on the vehicle status, thereby reducing power consumption.

[0021] With this structure, by temporarily stopping the display of advertising information on a portion of the multiple display units by means of the processor, the power consumption associated with the display of advertising information can be reduced during the stop period.

[0022] In the vehicles involved in the second method mentioned above,

[0023] The vehicle body has multiple display units on its outer surface.

[0024] The processor temporarily reduces the brightness of the advertising information displayed on a portion of the multiple display units based on the vehicle status, thereby reducing power consumption.

[0025] With this structure, the processor can reduce power consumption related to the display of advertising information by temporarily reducing the brightness of a portion of the display units among multiple display units. Furthermore, since the display of advertising information is not stopped, power consumption can be reduced while the advertisement is being displayed.

[0026] As described above, the vehicle advertising display device and vehicle according to the present invention can extend the driving range of the vehicle displaying the advertisement. Attached Figure Description

[0034] The system S, including the vehicle advertising display device 10 according to the embodiment, will be described with reference to the accompanying drawings.

[0035] (Overall structure)

[0036] like Figure 1 As shown, system S is configured to include a vehicle advertising display device 10, a server 12, and a vehicle V. Furthermore, the vehicle advertising display device 10, the server 12, and the vehicle V can communicate with each other via network N. Additionally, in Figure 1 As an example, the diagram shows one vehicle V, but the number of vehicles V is not limited to one; it can also include multiple vehicles V to form a system S.

[0037] Server 12 has a storage area (not shown) that stores data such as advertising information to be displayed on vehicle V. Additionally, server 12 stores data output from vehicle advertising display device 10. Furthermore, server 12 stores data output from vehicle V in its storage area. For example, server 12 stores information related to the vehicle status of vehicle V, the display time of the advertising information, and the content of the advertising information.

[0038] A side display section 16A and a rear display section 16B are provided on the outer surface of the vehicle body 14 of the vehicle V. The side display section 16A is provided on both sides of the vehicle body 14 in the vehicle width direction and is a display area for displaying advertising information. In addition, the rear display section 16B is provided on the rear side of the vehicle body 14 in the vehicle front-rear direction and is a display area for displaying advertising information.

[0039] When vehicle V receives a signal from vehicle advertising display device 10 indicating the intention to display an advertisement, it causes at least one of the side display unit 16A and the rear display unit 16B to display the prescribed advertising information. In this embodiment, as an example, advertising information obtained from server 12 is displayed, but the displayed advertising information is not limited to this. If advertising information is pre-stored in the storage unit of vehicle V, vehicle V can cause at least one of the side display unit 16A and the rear display unit 16B to display the stored advertising information.

[0040] System S is configured as described above. The vehicle advertising display device 10 in this embodiment is a structure that reduces the power consumption of vehicle V according to the vehicle status.

[0041] (Hardware structure of vehicle advertising display device 10)

[0042] Figure 2 This is a block diagram illustrating the hardware structure of an advertising display device for vehicles. For example... Figure 2 As shown, the vehicle advertising display device 10 is configured to include a central processing unit (CPU): 20, a read-only memory (ROM): 22, a random access memory (RAM): 24, a memory: 26, a communication interface (communication I / F): 28, and an input / output interface (input / output I / F): 30. All components are connected to each other via a bus 32.

[0043] CPU 20 is the central processing unit, which executes various programs and controls various parts. Specifically, CPU 20 reads programs from ROM 22 or memory 26 and uses RAM 24 as the working area to execute the programs. Furthermore, CPU 20 performs control and various arithmetic operations on the aforementioned structures according to the programs recorded in ROM 22 or memory 26.

[0044] ROM 22 stores various programs and data. RAM 24 is a non-temporary recording medium that temporarily stores programs or data as a working area. Memory 26, composed of a hard disk drive (HDD) or a solid-state drive (SSD), is a non-temporary recording medium that stores various programs and data, including the operating system. In this embodiment, memory 26 stores programs and various data used for display stop processing and brightness change processing.

[0045] Communication I / F28 is an interface for communication between the vehicle advertising display device 10 and the server 12 and other devices, for example, using standards such as Controller Area Network (CAN), Ethernet (registered trademark), Long Term Evolution (LTE), Fiber Distributed Data Interface (FDDI), and Wi-Fi (registered trademark).

[0046] The input / output I / F30 is an interface used by the vehicle advertising display device 10 to input and output with surrounding devices.

[0047] (Hardware structure of vehicle V)

[0048] Figure 3 This is a block diagram representing the hardware structure of vehicle V. (As shown...) Figure 3 As shown, the vehicle V is configured to include a central processing unit (CPU: processor) 34, a read-only memory (ROM) 36, a random access memory (RAM) 38, a memory 40, a communication interface (communication I / F) 42, and an input / output interface (input / output I / F) 44. All components are connected to each other via a bus 45.

[0049] CPU 34 is the central processing unit, which executes various programs and controls various parts. Specifically, CPU 34 reads programs from ROM 36 or memory 40 and executes the programs using RAM 38 as the working area. Furthermore, CPU 34 performs control and various arithmetic operations on the aforementioned structures according to the programs recorded in ROM 36 or memory 40.

[0050] ROM 36 stores various programs and data. RAM 38 is a non-temporary recording medium that temporarily stores programs or data as the operating area. Memory 40, composed of a hard disk drive (HDD) or a solid-state drive (SSD), is a non-temporary recording medium that stores various programs and data, including the operating system. In this embodiment, advertising information downloaded from server 12 is stored in memory 40.

[0051] Communication I / F42 is an interface used for communication between vehicle V and vehicle advertising display device 10, server 12 and other devices, for example using standards such as Controller Area Network (CAN), Ethernet (registered trademark), Long Term Evolution (LTE), Fiber Distributed Data Interface (FDDI), Wi-Fi (registered trademark).

[0052] As an example, the input / output I / F30 is electrically connected to a vehicle speed sensor 46, a global positioning system (GPS) device 47, an air conditioning device 48, a side display 16A, and a rear display 16B.

[0053] The vehicle speed sensor 46 is a sensor mounted on the vehicle V and detects the speed of the vehicle V. The GPS device 47 is a device that locates the current position of the vehicle V by receiving GPS signals from multiple GPS satellites.

[0054] An air conditioning unit 48 is installed in the vehicle V and is a device that delivers temperature-regulated air into the vehicle interior. As an example, in this embodiment, the air conditioning unit 48 regulates the temperature of air drawn in from outside the vehicle according to the interior temperature set by the occupants, and delivers air into the vehicle interior via a fan or the like, thereby bringing the interior temperature close to the set temperature.

[0055] As described above, the side display unit 16A is provided on both sides of the vehicle body 14 in the vehicle width direction, and is configured to include a liquid crystal display and an organic electroluminescent (EL) display, etc. Similarly, the rear display unit 16B is provided on the rear side of the vehicle body 14 in the vehicle front-rear direction, and is configured to include a liquid crystal display and an organic EL display, etc., in the same manner as the side display unit 16A.

[0056] In this embodiment, as an example, advertising information is displayed independently on the side display section 16A and the rear display section 16B. That is, the side display section 16A and the rear display section 16B are configured to display different advertising information respectively. In addition, the side display section 16A is configured to display different advertising information on the right side side display section 16A and the left side side side display section 16A of the vehicle body 14.

[0057] Furthermore, in this embodiment, as an example, the side display section 16A and the rear display section 16B are configured to stop the display of advertising information on a portion of the side display section 16A and the rear display section 16B on the left and right sides. For example, the display of advertising information on the side display section 16A on the right side of the vehicle body 14 can be stopped, while advertising information is displayed on both the side display section 16A and the rear display section 16B on the left side.

[0058] Furthermore, in this embodiment, as an example, the brightness of a portion of the side display 16A and the rear display 16B can be adjusted. For example, the brightness of the side display 16A on the right side of the vehicle body 14 can be reduced only.

[0059] Furthermore, as an example, the vehicle V in this embodiment is configured to be equipped with a navigation system that guides passengers to a destination from the vehicle V's current location. The guidance is performed by displaying the route on a monitor (not shown) located inside the vehicle interior.

[0060] (Functional structure of vehicle advertising display device 10)

[0061] Vehicle advertising display device 10 Figure 2 The hardware resources shown are used to implement various functions. (Refer to...) Figure 4 The functional structure of the vehicle advertising display device 10 is explained.

[0062] like Figure 4 As shown, the vehicle advertising display device 10 is configured as a functional structure including an advertising display control unit 50, a vehicle speed acquisition unit 52, a predetermined driving distance acquisition unit 54, a display stop unit 56, and a brightness reduction unit 58. Furthermore, each functional structure is implemented by the CPU 20 reading and executing a program stored in the ROM 22 or the memory 26.

[0063] The advertising display control unit 50 causes the side display units 16A and rear display units 16B of the vehicle V to display prescribed advertising information. Specifically, when the advertising display control unit 50 receives a signal to display an advertisement, it obtains advertising information from the server 12 and sends the advertising information to the vehicle V, thereby causing the side display units 16A and rear display units 16B to display the advertising information.

[0064] In addition, when the advertising information is stored in the memory 40 of the vehicle V, the advertising display control unit 50 can display the advertising information stored in the memory 40 on the side display unit 16A and the rear display unit 16B.

[0065] The vehicle speed acquisition unit 52 acquires information related to the speed of the vehicle V. Specifically, the vehicle speed acquisition unit 52 acquires information detected by the vehicle speed sensor 46 from the vehicle V.

[0066] The travel predetermined distance acquisition unit 54 acquires information related to the travel predetermined distance of the vehicle V. Specifically, the travel predetermined distance acquisition unit 54 acquires information related to the destination set in the navigation system installed in the vehicle V and information about the current location of the vehicle V located by the GPS device 47. Then, the travel predetermined distance acquisition unit 54 calculates the travel distance from the current location of the vehicle V to the destination to obtain the travel predetermined distance.

[0067] The display stop unit 56 stops displaying advertising information based on the vehicle status of vehicle V. Specifically, the display stop unit 56 stops displaying advertising information based on at least one of the speed-related information of vehicle V obtained by the vehicle speed acquisition unit 52 and the destination-related information obtained by the travel predetermined distance acquisition unit 54. Therefore, the display stop unit 56 functions as a power consumption reduction unit that reduces the power consumption of vehicle V based on the vehicle status of vehicle V.

[0068] The brightness reduction unit 58 reduces the display of advertising information based on the vehicle status of vehicle V. Specifically, the display stop unit 56 stops the display of advertising information based on at least one of the speed-related information of vehicle V obtained by the vehicle speed acquisition unit 52 and the destination-related information obtained by the travel predetermined distance acquisition unit 54. Therefore, the display stop unit 56 functions as a power consumption reduction unit that reduces the power consumption of vehicle V based on the vehicle status of vehicle V.

[0069] The following describes an example of how the power consumption of vehicle V is reduced by using the display stop unit 56 and the brightness reduction unit 58.

[0070] The display stop unit 56 does not stop displaying advertising information if the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is less than a preset first threshold. That is, when the vehicle speed of the vehicle V is less than the first threshold, the advertising information is maintained on both the side display unit 16A and the rear display unit 16B.

[0071] When the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is above a preset first threshold, the display stop unit 56 temporarily stops displaying a portion of the advertising information on the side display unit 16A and the rear display unit 16B. For example, when the vehicle speed is above the first threshold, the display stop unit 56 stops displaying the advertising information on the side display unit 16A, thereby reducing power consumption. At this time, the advertising information is displayed on the rear display unit 16B. Furthermore, when the vehicle speed of the vehicle V shifts to a state below the first threshold, the display stop state initiated by the display stop unit 56 is lifted, and the display of the advertising information on the side display unit 16A resumes.

[0072] If the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is above a preset second threshold, the display stop unit 56 stops displaying all advertising information on the side display unit 16A and the rear display unit 16B. Here, the second threshold is set to a value greater than the first threshold; the second threshold is set to a speed at which people around the vehicle V cannot adequately observe the side display unit 16A and the rear display unit 16B. Furthermore, if the vehicle speed of the vehicle V shifts to a state below the second threshold, the display stop state initiated by the display stop unit 56 is lifted, and the display of advertising information on the rear display unit 16B resumes. Even in this case, the display of advertising information on the side display unit 16A is stopped when the vehicle speed of the vehicle V is above the first threshold.

[0073] Furthermore, when the predetermined driving distance obtained by the driving predetermined distance acquisition unit 54 is a predetermined first distance or more, the display stop unit 56 reduces power consumption by stopping the display of a portion of the advertising information displayed on the side display unit 16A and the rear display unit 16B. For example, when the predetermined driving distance is a first distance or more, the display stop unit 56 reduces power consumption by stopping the display of the advertising information displayed on the side display unit 16A.

[0074] When the predetermined distance traveled is greater than or equal to a second predetermined distance, the display stop unit 56 stops displaying all advertising information on the side display unit 16A and the rear display unit 16B. Here, the second distance is set to a value greater than the first distance.

[0075] If the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is less than a preset third threshold, the brightness reduction unit 58 does not reduce the brightness of the displayed advertising information. That is, when the vehicle speed of the vehicle V is less than the third threshold, the advertising information displayed on the side display unit 16A and the rear display unit 16B does not change from the initial brightness value.

[0076] When the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is above a preset third threshold, the brightness reduction unit 58 temporarily reduces the brightness of a portion of the side display unit 16A and the rear display unit 16B. For example, when the vehicle speed is above the third threshold, the brightness reduction unit 58 reduces power consumption by decreasing the brightness of the side display unit 16A. At this time, the brightness of the rear display unit 16B remains unchanged. Furthermore, when the vehicle speed of the vehicle V shifts to a state below the third threshold, the brightness change performed by the brightness reduction unit 58 is deactivated, and the brightness of the side display unit 16A returns to its initial value.

[0077] When the vehicle speed of the vehicle V, as determined by the vehicle speed acquisition unit 52, is above a preset fourth threshold, the brightness reduction unit 58 reduces the brightness of both the side display unit 16A and the rear display unit 16B. Here, the fourth threshold is set to a value greater than the third threshold. Furthermore, when the vehicle speed of the vehicle V shifts to a state below the fourth threshold, the brightness change performed by the brightness reduction unit 58 is canceled, and the brightness of the rear display unit 16B returns to its initial value. Even in this case, when the vehicle speed of the vehicle V is above the third threshold, the brightness of the side display unit 16A remains reduced. Moreover, the relationship between the first and third thresholds, and the magnitude relationship between the second and fourth thresholds, are not particularly limited.

[0078] Furthermore, when the predetermined driving distance obtained by the predetermined driving distance acquisition unit 54 is a predetermined third distance or more, the brightness reduction unit 58 reduces power consumption by reducing the brightness of a portion of the side display unit 16A and the rear display unit 16B. For example, when the predetermined driving distance is a third distance or more, the display stop unit 56 reduces power consumption by reducing the brightness of the side display unit 16A.

[0079] When the predetermined travel distance is a predetermined fourth distance or more, the brightness reduction unit 58 reduces the brightness of both the side display unit 16A and the rear display unit 16B. Here, the fourth distance is set to a value larger than the third distance. Furthermore, the relationship between the first and third distances, and the magnitude relationship between the second and fourth distances, are not particularly limited.

[0080] (effect)

[0081] Next, the function of this embodiment will be explained.

[0082] (Showing an example of a process that has stopped)

[0083] Figure 5 This is a flowchart illustrating an example of the display stop processing performed by the vehicle advertising display device 10 in this embodiment. The advertising display processing is executed by the CPU 20 reading the program from the memory 26 and unfolding it in the RAM 24.

[0084] like Figure 5 As shown, CPU 20 begins displaying advertising information in step S102. Specifically, CPU 20 displays advertisements on the side display unit 16A and rear display unit 16B of the vehicle V using the functions of the advertising display control unit 50. For example, the content of the advertising information to be displayed is selected based on signals received from the outside.

[0085] In step S104, CPU 20 obtains the vehicle speed and the predetermined travel distance. Specifically, CPU 20 obtains the vehicle speed information through the function of vehicle speed acquisition unit 52. In addition, CPU 20 obtains the predetermined travel distance information through the function of predetermined travel distance acquisition unit 54.

[0086] In step S106, CPU 20 determines whether the predetermined travel distance is greater than or equal to a first distance. If the predetermined travel distance obtained by the predetermined travel distance acquisition unit 54 is greater than or equal to the first distance, CPU 20 proceeds to step S110. Otherwise, if the predetermined travel distance is less than the first distance, CPU 20 proceeds to step S108. First, the processing after step S108 will be explained; the processing after step S110 will be described later.

[0087] In step S108, CPU 20 determines whether the vehicle speed is above a first threshold. If the vehicle speed of vehicle V, as obtained by vehicle speed acquisition unit 52, is above the first threshold, CPU 20 proceeds to step S112. Conversely, if the vehicle speed of vehicle V is below the first threshold, CPU 20 terminates the display stop process. That is, if the predetermined distance traveled is less than a first distance and the vehicle speed is less than the first threshold, CPU 20 terminates the display stop process without stopping the display of the advertising information.

[0088] On the other hand, if it is determined in step S108 that the vehicle speed of vehicle V is above the first threshold, CPU 20 determines in step S112 whether the vehicle speed is above the second threshold. If the vehicle speed of vehicle V is above the second threshold, CPU 20 transfers the processing to step S116. Conversely, if the vehicle speed of vehicle V is below the second threshold, CPU 20 transfers the processing to step S114.

[0089] In step S114, the CPU 20 temporarily stops the display of the side display unit 16A. Specifically, the CPU 20 stops the display of advertising information on the side display units 16A located on the right and left sides of the vehicle body 14 by using the function of the display stop unit 56. Then, the CPU 20 ends the display stop process. That is, when the predetermined driving distance is less than a first distance and the vehicle speed is between a first threshold and a second threshold, the CPU 20 only stops the display of the side display unit 16A and ends the display stop process.

[0090] If the predetermined travel distance is greater than or equal to a first distance in step S106, the CPU 20 proceeds to step S110 to determine whether the predetermined travel distance is greater than or equal to a second distance. If the predetermined travel distance obtained by the predetermined travel distance acquisition unit 54 is greater than or equal to a second distance, the CPU 20 proceeds to step S116. Conversely, if the predetermined travel distance is less than the second distance, the CPU 20 proceeds to step S114, temporarily suspending the display on the side display unit 16A.

[0091] If, in step S110, it is determined that the predetermined travel distance is greater than or equal to a second distance, and in step S112, it is determined that the vehicle speed of vehicle V is greater than or equal to a second threshold, the CPU 20 transfers the processing to step S116 and stops all displays. Specifically, the CPU 20 stops the displays of both the side display unit 16A and the rear display unit 16B by using the function of the display stop unit 56.

[0092] (An example of brightness change processing)

[0093] Figure 6 This is a flowchart illustrating an example of the brightness change processing performed by the vehicle advertising display device 10 in this embodiment. The advertising display processing is executed by the CPU 20 reading the program from the memory 26 and unfolding it in the RAM 24.

[0094] like Figure 6 As shown, in step S202, CPU 20 begins displaying advertising information. Specifically, CPU 20 displays advertisements on the side display unit 16A and rear display unit 16B of the vehicle V using the functions of the advertising display control unit 50. For example, the content of the advertising information to be displayed is selected based on signals received from the outside.

[0095] In step S204, CPU 20 obtains the vehicle speed and the predetermined travel distance. Specifically, CPU 20 obtains the vehicle speed information through the function of the vehicle speed acquisition unit 52. Additionally, CPU 20 obtains the predetermined travel distance information through the function of the predetermined travel distance acquisition unit 54.

[0096] In step S206, CPU 20 determines whether the predetermined travel distance is a third distance or more. If the predetermined travel distance obtained by the predetermined travel distance acquisition unit 54 is a third distance or more, CPU 20 proceeds to step S210. Otherwise, if the predetermined travel distance is less than a third distance, CPU 20 proceeds to step S208. First, the processing after step S208 will be explained; the processing after step S210 will be described later.

[0097] In step S208, CPU 20 determines whether the vehicle speed is above the third threshold. If the vehicle speed of vehicle V, as obtained by vehicle speed acquisition unit 52, is above the third threshold, CPU 20 proceeds to step S212. Conversely, if the vehicle speed of vehicle V is below the third threshold, CPU 20 terminates the brightness change process. That is, if the predetermined distance traveled is less than the third distance and the vehicle speed is less than the third threshold, CPU 20 terminates the brightness change process without changing the brightness of the display unit.

[0098] On the other hand, if it is determined in step S208 that the vehicle speed of vehicle V is above the third threshold, CPU 20 determines in step S212 whether the vehicle speed is above the fourth threshold. If the vehicle speed of vehicle V is above the fourth threshold, CPU 20 transfers the processing to step S216. Conversely, if the vehicle speed of vehicle V is below the fourth threshold, CPU 20 transfers the processing to step S214.

[0099] In step S214, the CPU 20 temporarily reduces the brightness of the side display unit 16A. Specifically, the CPU 20 reduces the brightness of the side display units 16A located on the right and left sides of the vehicle body 14 using the function of the brightness reduction unit 58. Then, the CPU 20 ends the brightness change process. That is, when the predetermined driving distance is less than a third distance and the vehicle speed is between a third threshold and a fourth threshold, the CPU 20 only reduces the brightness of the side display unit 16A and ends the brightness change process.

[0100] If the predetermined travel distance is a third distance or more in step S206, the CPU 20 proceeds to step S210 to determine whether the predetermined travel distance is a fourth distance or more. If the predetermined travel distance obtained by the predetermined travel distance acquisition unit 54 is a fourth distance or more, the CPU 20 proceeds to step S216. Alternatively, if the predetermined travel distance is less than a fourth distance, the CPU 20 proceeds to step S214 to temporarily reduce the brightness of the side display unit 16A.

[0101] If, in step S210, it is determined that the predetermined travel distance is greater than or equal to the fourth distance, and in step S212, it is determined that the vehicle speed of vehicle V is greater than or equal to the fourth threshold, the CPU 20 transfers the processing to step S216 and reduces the brightness of all display units. Specifically, the CPU 20 reduces the brightness of both the side display unit 16A and the rear display unit 16B through the function of the brightness reduction unit 58.

[0102] As described above, in the vehicle advertising display device 10 according to this embodiment, by displaying advertising information on the side display portion 16A and the rear display portion 16B provided on the outer surface of the vehicle body 14, people around the vehicle V can visually recognize the advertisement. In addition, by reducing the power consumption of the vehicle V according to the vehicle status, the CPU 20 can enable the vehicle V to travel for a longer time compared to a structure that does not consider power consumption.

[0103] Furthermore, in this embodiment, when the vehicle speed exceeds a predetermined speed, the CPU 20 reduces the power consumption related to the display of advertising information. At higher vehicle speeds, people around the vehicle V may not be able to see the advertising information, thus the effect of displaying the advertising information is likely to be insufficient. Therefore, by reducing the power consumption related to the display of advertising information at higher vehicle speeds, the power used for displaying the advertising information can be used for vehicle operation.

[0104] Furthermore, in this embodiment, when the distance to the destination is greater than the predetermined distance, the CPU 20 reduces the power consumption for display. Therefore, it is possible to prevent the fuel from running out before reaching the destination.

[0105] In particular, in this embodiment, by temporarily stopping the display of advertising information on a portion of the side display section 16A and the rear display section 16B by display stop section 56, the power consumption related to the display of advertising information can be reduced during the stop period.

[0106] In this embodiment, the CPU 20 preferably stops the display of advertising information in the side display unit 16A from being displayed in the rear display unit 16B. This makes it easy to maintain the display of advertising information in the rear display unit 16B, thus enabling advertising information to be provided to occupants of following vehicles traveling behind the vehicle V even when traveling at a certain speed.

[0107] Furthermore, by temporarily reducing the brightness of the advertising information display on a portion of the side display section 16A and the rear display section 16B through the brightness reduction unit 58, the power consumption related to the display of the advertising information can be reduced during the brightness reduction period. In this case, since the display of the advertising information is not stopped, power consumption can be reduced while displaying the advertisement.

[0108] The vehicle advertising display device 10 according to the embodiments and variations has been described above, but it can of course be implemented in various ways without departing from the spirit of the present invention. For example, in the above embodiments, the structure of reducing the power consumption of the vehicle V by means of the functions of the display stop section 56 and the brightness reduction section 58 has been described, but it is not limited to this, and the power consumption of the vehicle V can also be reduced by other functions.

[0109] For example, vehicle V may also have an air conditioning control unit that controls the air conditioning unit 48 of vehicle V, and may be configured to reduce the power consumption of vehicle V through the air conditioning control unit. The air conditioning control unit may also reduce the power consumption of vehicle V by temporarily stopping or reducing the air conditioning function of air conditioning unit 48 when the predetermined travel distance to the destination of vehicle V is greater than a predetermined distance. Specifically, when the temperature difference between the outside air and the interior of the vehicle is small, and the air conditioning unit 48 can be stopped, the air conditioning control unit temporarily stops the air conditioning unit 48, thereby allowing the power consumed by the air conditioning unit 48 to be used for driving. Furthermore, when the temperature difference between the outside air and the interior of the vehicle is large, the function of the air conditioning control unit changes the set temperature to be closer to the outside air temperature, thereby reducing the power consumption of air conditioning unit 48.

[0110] As another example, for the CPU 34 of vehicle V, power consumption can be reduced by stopping a portion of the CPU 34's processing. In this case, by stopping functions not required for the operation of vehicle V, the processing load on CPU 34 can be reduced, resulting in a reduction in the power consumption of vehicle V.

[0111] Furthermore, in the above embodiment, a structure is provided that stops the display or reduces the brightness of the display unit based on vehicle speed and a predetermined distance traveled, but the structure is not limited to this. For example, a structure could also be provided that stops the display or reduces the brightness of the display unit based on vehicle status such as the number of passengers and the amount of cargo loaded. When the number of passengers and the amount of cargo loaded are large, the vehicle V requires more energy to travel. In such cases, by stopping the display of the side display unit 16A and the rear display unit 16B, the power required for displaying advertising information can be used for the travel of the vehicle V. In this way, the energy usage ratio can be allocated according to the preferred order of displaying advertising information and extending the driving range.

[0112] Furthermore, in the display stop processing of the above embodiment, the display of the side display unit 16A is stopped when the vehicle speed is above a first threshold and below a second threshold, and the display of all display units is stopped when the vehicle speed is above the second threshold. However, the display stop processing is not limited to this. For example, it may be configured to stop the display of the rear display unit 16B when the vehicle speed is above the first threshold and below the second threshold. Alternatively, it may be configured to stop the display of all display units when the vehicle speed is above the first threshold. Moreover, it may be configured to set a first index value corresponding to the vehicle speed and a second index value corresponding to a predetermined driving distance, and stop the display of the display units based on the sum of the first index value and the second index value.

[0113] Similar to the display stop processing, the brightness change processing can also be configured to stop the display based on the sum of the first and second index values. Alternatively, the occupant can choose between display stop processing and brightness change processing.

[0114] Furthermore, in the above embodiment, the structure in which the vehicle display control device 10 is provided on the outside of the vehicle V has been described, but it is not limited to this. For example, it is also possible to configure the structure in which the vehicle display control device 10 is mounted on the vehicle V.

[0115] Furthermore, various processors other than CPU 20 can also execute the process of reading and executing the program by CPU 20 in the above embodiment. Examples of processors in this case include programmable logic devices (PLDs) and dedicated circuits. The circuit structure of a PLD can be modified after the manufacture of a field-programmable gate array (FPGA), etc., and the dedicated circuit is a processor such as an application-specific integrated circuit (ASIC) with a circuit structure specifically designed for executing a specific process. Furthermore, each process can be executed by one of these various processors, or by a combination of two or more processors of the same or different types. For example, it can be executed by multiple FPGAs or a combination of a CPU and an FPGA. More specifically, the hardware structure of these various processors is a circuit that combines circuit elements such as semiconductor elements.

[0116] Furthermore, in the above embodiments, the method described is based on each program being pre-stored (installed) on a computer-readable non-transitory recording medium. However, this is not a limitation. Each program may also be provided in a manner recorded on a non-transitory recording medium such as a CD-ROM, a DVD-ROM, or a USB memory. Alternatively, the program may be downloaded from an external device via a network.

[0117] Furthermore, the processing flow described in the above embodiments is an example, and unnecessary steps can be deleted, new steps can be added, or the processing order can be replaced without departing from the main idea.
