<First Embodiment>
[Display control device configuration]
FIG. 1 is a diagram showing an example of the configuration of the display control device 100 according to the first embodiment. The display control device 100 according to the first embodiment is mounted on a moving body. The moving body is, for example, a vehicle such as a two-wheeled vehicle, a three-wheeled vehicle, or a four-wheeled vehicle. The moving body on which the display control device 100 is mounted is not limited to a vehicle, and may be another moving body such as an aircraft such as a passenger plane or an airship or a ship such as a passenger ship. Hereinafter, as an example, it is assumed that the moving body is a vehicle, and a vehicle on which the display control device 100 is mounted will be referred to as "own vehicle M".

The drive source of the vehicle is, for example, an electric motor that operates using the discharge power of a secondary battery or a fuel cell. Further, the drive source of the vehicle may be an internal combustion engine such as a diesel engine or a gasoline engine, or may be a combination of an internal combustion engine and an electric motor. When the drive source of the vehicle is a combination of an internal combustion engine and an electric motor, the electric motor may operate using the electric power generated by the generator connected to the internal combustion engine.

The display control device 100 includes, for example, a display unit 102, a GNSS (Global Navigation Satellite System) receiver 104, a communication unit 106, a storage unit 110, and a control unit 120.

The display unit 102 is a display such as an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display, and has a display screen 102A on which information such as characters and images is displayed. The display unit 102 displays information on the display screen 102A based on the information output by the control unit 120. The display unit 102 is attached to the own vehicle M with the display screen 102A facing the outside of the own vehicle M.

FIG. 2 is a diagram showing an example of the own vehicle M to which the display unit 102 is attached. As shown in the figure, for example, the display unit 102 is attached to the front of the own vehicle M with the display screen 102A facing the front of the own vehicle M. Further, the display unit 102 may be attached to the rear of the own vehicle M with the display screen 102A facing the rear of the own vehicle M, or the display unit 102 may be attached to the rear of the own vehicle M with the display screen 102A facing the side of the own vehicle M.

These components are realized, for example, by executing a program (software) by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). In addition, some or all of these components are determined by hardware (including circuit section; circuitry) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), and FPGA (Field-Programmable Gate Array). It may be realized, or it may be realized by the cooperation of software and hardware. The program may be stored in the storage unit 110 in advance, or is stored in a removable storage medium such as a DVD or a CD-ROM, and is installed in the storage unit 110 when the storage medium is attached to the drive device. May be done.

The acquisition unit 122 acquires the position information of the own vehicle M from the GNSS receiver 104. When the communication unit 106 communicates with an external server, the acquisition unit 122 acquires an IP address (Internet Protocol Address) from a wireless relay device or an external server included in the network via the communication unit 106, and obtains the IP address (Internet Protocol Address). The position information of the own vehicle M may be acquired based on the address. Specifically, the acquisition unit 122 may acquire information such as a continent, a country, a region, a city, a latitude, a route, and a zip code included in the IP address as the position information of the own vehicle M.

The determination unit 124 determines the area or country where the own vehicle M exists based on the position information acquired by the acquisition unit 122. For example, the determination unit 124 may determine the area or country where the own vehicle M exists based on the latitude and longitude acquired as position information from the GNSS receiver 104. Further, the determination unit 124 may determine the area or country where the own vehicle M exists based on the IP address acquired as the position information by the acquisition unit 122. The "region or country" in the embodiment is an example of the "region" in the claims.

The display control unit 126 determines the content based on the determination result of the determination unit 124, and causes the display unit 102 to display the determined content. The content is, for example, identification information that identifies the own vehicle M.

The communication control unit 128 causes the communication unit 106 to communicate with an external server or the like.

[Processing flow of display control device]
Hereinafter, a series of processing flows of the display control device 100 according to the first embodiment will be described with reference to a flowchart. FIG. 3 is a flowchart showing a series of processing flows of the display control device 100 according to the first embodiment. The processing of this flowchart may be repeated, for example, at a predetermined cycle.

First, the acquisition unit 122 acquires the position information of the own vehicle M from the GNSS receiver 104, or acquires the position information of the own vehicle M from the IP address (step S100).

Next, the determination unit 124 determines the area or country where the own vehicle M exists based on the position information acquired by the acquisition unit 122 (step S102).

Next, the display control unit 126 determines the content to be displayed on the display unit 102 according to the region or country determined by the determination unit 124 (step S104).

Next, the display control unit 126 causes the display unit 102 to display the determined content (step S106). This ends the processing of this flowchart.

FIG. 4 is a diagram showing an example of a scene in which content corresponding to a region or a country is displayed. For example, when the own vehicle M exists in the first country or the first region, the display control unit 126 displays the content to be displayed in the first country or the first region by the name of the type of vehicle that identifies the own vehicle M (hereinafter,). , This is referred to as a first vehicle name), and the first vehicle name (“ABCDE” in the illustrated example) is displayed on the display unit 102. For example, the own vehicle M whose first vehicle name is displayed on the display unit 102 crosses a border or the like and enters another second country from the first country, or from the first region to another second region. When entering, the display control unit 126 determines the content to be displayed in the second country or the second region to the second vehicle name (“KLMNO” in the illustrated example) different from the first vehicle name. The second vehicle name is displayed on the display unit 102. The first vehicle name is an example of the "first name", and the second vehicle name is an example of the "second name".

For example, in the first country or the first region, when the name interpreted as "A" is given to the vehicle as the first vehicle name, the first vehicle name is the second country or the second region. Then, it is often interpreted as another meaning of "B". In consideration of this, vehicle manufacturers may name and sell vehicles with different names for each country or region. When the display control device 100 according to the first embodiment determines the country or region in which the own vehicle M exists, the display unit 102 automatically displays an appropriate vehicle name according to the country or region. As a result, for example, it is possible to inform people outside the vehicle who are concerned about the vehicle name of the own vehicle M of the vehicle name appropriately named according to the country or region. Also, for example, when the country or region where the vehicle is sold is different, the work of reprogramming to change the displayed content or re-installing the content at the sales base of each country or region is omitted. can do.

According to the first embodiment described above, the display control device 100 includes a display unit 102 in which the display screen 102A is directed to the outside of the own vehicle M, a display control unit 126 for displaying information on the display unit 102, and the self. The display control unit 126 includes an acquisition unit 122 that acquires the position information of the vehicle M, and a determination unit 124 that determines the area or country where the own vehicle M exists based on the position information acquired by the acquisition unit 122. However, in order to display different vehicle names on the display unit 102 depending on the region or country determined by the determination unit 124, the country or the region is given to people outside the vehicle who are concerned about the vehicle name of the own vehicle M. It is possible to disseminate an appropriately named vehicle name according to the above.

<Second Embodiment>
Hereinafter, the second embodiment will be described. In the first embodiment described above, the display control device 100 has been described as having the display unit 102 display the names of vehicles different from each other depending on the country or region in which the own vehicle M exists. On the other hand, in the second embodiment, the own vehicle M is an electric vehicle, and when charging the secondary battery mounted on the electric vehicle, the display unit 102 displays various information. It differs from the first embodiment. Hereinafter, the differences from the first embodiment will be mainly described, and the points common to the first embodiment will be omitted. In the description of the second embodiment, the same parts as those of the first embodiment will be described with the same reference numerals.

FIG. 5 is a diagram showing an example of the configuration of the display control system 1 including the display control device 100 according to the second embodiment. The own vehicle M according to the second embodiment is an electric vehicle. An electric vehicle is a vehicle driven by an electric motor that operates by using the discharge power of a secondary battery. The electric vehicle may be a hybrid vehicle in which the drive source is a combination of an electric motor and an internal combustion engine.

The display control system 1 includes, for example, a display control device 100 and a charge monitoring device 200. The display control device 100 and the charge monitoring device 200 are connected to each other by an internal bus BS. The internal bus BS may be, for example, a multiplex communication line such as a CAN (Controller Area Network) communication line or a serial communication line. In addition, these devices may be connected to each other by wireless communication. The configuration shown in FIG. 5 is merely an example, and a part of the configuration may be omitted or another configuration may be added.

The display control device 100 according to the second embodiment further includes a camera 108 in addition to the above-described configuration. The camera 108 is a camera that captures the inside of the own vehicle M. The camera 108 is, for example, a digital camera using a solid-state image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). When the camera 108 takes an image of the inside of the own vehicle M, it generates image data and outputs this image data to the control unit 120. The image data may be, for example, a still image or a moving image (video) in which the still image is continuous in time series.

Further, the control unit 120 according to the second embodiment further includes an in-vehicle monitoring unit 130 in addition to the above-described configuration. The vehicle interior monitoring unit 130 monitors the interior of the own vehicle M based on the images and videos captured by the camera 108.

The charge monitoring device 200 includes, for example, a secondary battery 210, a sensor 220, a charging port 230, a storage unit 240, and a charge monitoring control unit 250.

The secondary battery 210 is, for example, a secondary battery such as a lithium ion battery or a lead storage battery. The secondary battery 210 stores electric power supplied from the outside. Under the control of the charge monitoring control unit 250, the secondary battery 210 discharges the stored electric power and supplies the discharged electric power to the electric motor which is the drive source of the own vehicle M.

The sensor 220 includes, for example, a current sensor, a voltage sensor, a temperature sensor, and the like. For example, the sensor 220 detects the current charged in the secondary battery 210 and the current discharged from the secondary battery 210, and detects the voltage applied to the secondary battery 210 and the temperature of the secondary battery 210. To do. The sensor 220 outputs the detected current value, voltage value, temperature, etc. to the charge monitoring control unit 250.

The charging port 230 is a jack or socket into which the charging plug 302 of the charger 300 is inserted. The charging port 230 is an example of a “power supply port for a secondary battery”.

The storage unit 240 is realized by an HDD, a flash memory, an EEPROM, a ROM (Read Only Memory), a RAM, or the like. The storage unit 240 stores, for example, a program referenced by the processor.

The charge monitoring control unit 250 is realized by, for example, a processor such as a CPU or GPU executing a program (software). Further, the charge monitoring control unit 250 may be realized by hardware (including a circuit unit; circuitry) such as LSI, ASIC, and FPGA, or may be realized by collaboration between software and hardware. The program may be stored in the storage unit 240 in advance, or is stored in a removable storage medium such as a DVD or a CD-ROM, and is installed in the storage unit 240 when the storage medium is attached to the drive device. May be done.

The charge monitoring control unit 250 calculates the charge rate of the secondary battery 210 based on the detection result of the sensor 220. The charge rate may be, for example, SOC (State Of Charge) obtained by dividing the remaining capacity by the full charge capacity. The charge monitoring control unit 250 charges the secondary battery 210 with the electric power supplied from the charger 300 electrically connected via the charging port 230, or causes the secondary battery 210 to charge according to the calculated charge rate. It discharges the stored power.

[Display control system processing flow]
Hereinafter, a series of processing flows of the display control system 1 according to the second embodiment will be described with reference to a flowchart. FIG. 6 is a flowchart showing a series of processing flows of the display control system 1 according to the second embodiment. The processing of this flowchart may be repeated at a predetermined cycle, for example, when the own vehicle M stops at the charging spot. The charging spot is, for example, a charging facility in which a charger 300 capable of supplying electric power to an electric vehicle is installed. Charging spots are also called charging stations or charging points.

First, the charge monitoring control unit 250 of the charge monitoring device 200 waits until the charging plug 302 of the charger 300 is electrically connected to the charging port 230 of the own vehicle M (step S200), and the charging port 230 When the charging plug 302 is electrically connected to the charging plug 302, the power supplied from the charging plug 302 is charged to the secondary battery 210 (step S202).

Next, the charge monitoring control unit 250 calculates the time required for the secondary battery 210 to be fully charged (hereinafter referred to as the required charging time) based on the detection result of the sensor 220 (step S204).

When the charge monitoring control unit 250 calculates the required charging time, the charge monitoring control unit 250 transmits information representing the time to the display control device 100 via the internal bus BS. In response to this information, the display control unit 126 of the display control device 100 causes the display unit 102 to display the required charging time (step S206).

Next, the charge monitoring control unit 250 refers to the charge rate of the secondary battery 210 and determines whether or not the secondary battery 210 is fully charged (step S208).

When the secondary battery 210 is not fully charged, the charge monitoring control unit 250 returns the process to S204 and recalculates the required charging time based on the detection result of the sensor 220. As a result, the charging time displayed on the display unit 102 is repeatedly updated until the secondary battery 210 is fully charged.

On the other hand, when the secondary battery 210 is fully charged, the charge monitoring control unit 250 stops charging the secondary battery 210 with the power supplied from the charging plug 302 (step S210), and charging is completed. The charge completion information indicating that the battery has been charged is transmitted to the display control device 100 via the internal bus BS.

Next, when the in-vehicle monitoring unit 130 of the display control device 100 receives the charging completion information by the communication unit 106, the user gets in the vehicle of the own vehicle M based on the image or video captured by the camera 108. It is determined whether or not the operation is performed (step S212).

When a user is in the vehicle of the own vehicle M, the in-vehicle monitoring unit 130 further determines whether or not the user is awake (step S214).

For example, the in-vehicle monitoring unit 130 determines whether or not the user is awake according to the degree of opening and closing of the user's eyelids. Specifically, the in-vehicle monitoring unit 130 analyzes the image or video captured by the camera 108, identifies the eye area from the feature information of the user's face, and based on the color information of the specified eye area. The display area (area on the image) of the eyeball portion in the image is estimated. Then, the in-vehicle monitoring unit 130 states that the eyelids are closed when the estimated display area of the eyeball portion is hidden by the eyelids to be equal to or less than a predetermined value and the state continues for a predetermined time or longer. judge. Further, the in-vehicle monitoring unit 130 may determine that the eyelids are closed when the display area of the eyelids in the captured image is equal to or larger than a predetermined value. Further, when the display area of the eyeball portion is larger than a predetermined value, the vehicle interior monitoring unit 130 determines that the eyelids are in the open state. The in-vehicle monitoring unit 130 determines that the user is awake if the eyelids are open, and determines that the user is not awake if the eyelids are closed.

Further, for example, the in-vehicle monitoring unit 130 may determine whether or not the user is awake depending on whether or not the user is operating. Specifically, the in-vehicle monitoring unit 130 analyzes images and videos captured by the camera 108 to identify body parts such as the user's upper body, arms, and hands, and the specified parts are located within a predetermined time. Judge whether or not it has operated more than a certain amount. For example, the in-vehicle monitoring unit 130 determines that there is a movement of the user's body when the specified part moves by a predetermined amount or more within a predetermined time, and when the specified part does not move by a predetermined amount or more, the movement of the user's body. Judge that there is no. The in-vehicle monitoring unit 130 determines that the user is awake if there is a physical movement of the user, and determines that the user is not awake if there is no physical movement of the user.

Further, the in-vehicle monitoring unit 130 determines whether or not the user is awake according to the degree of opening and closing of the user's eyelids and the presence or absence of the user's movement, or in addition, the own vehicle M. It may be determined whether or not the user is awake based on the detection result of the load sensor (not shown) provided in each seat provided in the above and the detection result of the biosensor (not shown). The load sensor is a sensor that detects the load applied to the seat. The biosensor detects biometric information such as heart rate, body temperature, and voice, for example. The biosensor may be a wearable device capable of communicating with the display control device 100, or may be a device installed on the steering wheel, instrument panel, or the like of the own vehicle M.

Specifically, the in-vehicle monitoring unit 130 awakens the user because the user operates when the amount of change in the load detected by the load sensor changes by a predetermined amount or more within a predetermined time. If it does not change by a predetermined amount or more, it may be determined that the user is not awake because there is no movement of the user.

Further, for example, in the in-vehicle monitoring unit 130, the heart rate detected as biometric information by the biological sensor is reduced to about the heart rate during sleep, or the detected body temperature is reduced to about the body temperature during sleep. When the user's snoring is detected, it may be determined that the user is not awake.

When a user is in the vehicle of the own vehicle M and the user is awake, the in-vehicle monitoring unit 130 ends the process of this flowchart.

On the other hand, if the user is not in the vehicle M of the own vehicle M, or if the user is in the vehicle of the own vehicle M but the user is not awake, the display control unit 126 is used. The content related to the contact information of the person is displayed on the display unit 102 (step S216). This ends the processing of this flowchart.

FIG. 7 is a diagram showing an example of a scene in which content related to a user's contact information is displayed. As shown in the illustrated example, it is assumed that the charging plug 302 connected to the charger 300 via the cable 304 is connected to the own vehicle M and the charging of the secondary battery 210 is started. Generally, the charging capacity (battery capacity) of the secondary battery 210 loaded in an electric vehicle is as large as several tens [kWh] to several hundreds [kWh], and it tends to take a long time to charge. Therefore, the user may take a nap in the vehicle or go out of the vehicle until the charging of the secondary battery 210 is completed. However, even if the charging of the secondary battery 210 is completed, the user may not wake up or may not return to the own vehicle M from outside, and the charger 300 may continue to be occupied. ..

Therefore, in the display control unit 126, when the user is not in the vehicle M of the own vehicle M when the charging of the secondary battery 210 is completed, or the user is in the vehicle of the own vehicle M, the display control unit 126 is in the vehicle. When the user is not awake, a two-dimensional code MK such as a QR code (registered trademark, hereinafter omitted) is displayed on the display unit 102 as content related to the user's contact information. The two-dimensional code MK is image information in which information such as a user's mobile phone, e-mail address, token or certificate for push notification is encoded (encrypted or encoded).

In this way, by displaying the contact information of the user of the own vehicle M as a two-dimensional code MK, the contact information of the user is transmitted to the people around the own vehicle M while keeping the personal information of the user secret. Can be done. For example, when a user of another vehicle who plans to use the charger 300 next starts a dedicated application installed on a mobile phone or the like and reads the two-dimensional code MK with a camera, the user's mobile phone From the telephone, a telephone is connected to the mobile phone of the user of the own vehicle M, and an email or a push notification is sent. As a result, it is possible to awaken the user inside the own vehicle M and urge the user outside the vehicle to return to the own vehicle M. Further, since the display unit 102 displays not only the character information but also the two-dimensional code MK, the contact information of the user can be notified to a person who uses a different language such as a foreigner.

In the description of the second embodiment described above, it is assumed that the charge monitoring device 200 continues charging until the secondary battery 210 is fully charged, and stops charging when the secondary battery 210 is fully charged. However, it is not limited to this. For example, the charge monitoring device 200 may continue charging up to a target charge rate set in advance by the user, and stop charging when the secondary battery 210 is charged to the target charge rate. Further, the charge monitoring device 200 may continue charging until a predetermined time set in advance by the user elapses, and may stop charging when the predetermined time set by the user elapses.
