[Processing Flow of Display Control Device]
A series of processing flows of the display control device 100 according to the first embodiment will be described below using a flowchart. FIG. 3 is a flow chart showing a series of processes of the display control device 100 according to the first embodiment. The processing of this flowchart may be performed repeatedly at a predetermined cycle, for example.

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 region or country where the host vehicle M is located based on the position information acquired by the acquisition unit 122 (step S102).

Next, the display control unit 126 determines 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 completes the processing of this flowchart.

FIG. 4 is a diagram showing an example of a scene in which content according to region or country is displayed. For example, when the host vehicle M exists in the first country or the first region, the display control unit 126 sets the content to be displayed in the first country or the first region to the name of the vehicle type that identifies the host vehicle M (hereinafter referred to as , which will be referred to as the first car name), and causes the display unit 102 to display the first car name ("ABCDE" in the illustrated example). For example, the own vehicle M whose first vehicle name is displayed on the display unit 102 passes through a border or the like and enters a second country from a first country, or moves from a first area to a second area. When entering the vehicle, the display control unit 126 determines the content to be displayed in the second country or the second region to be a second car name different from the first car name ("KLMNO" in the illustrated example), The second car name is displayed on the display unit 102 . The first car name is an example of a "first name", and the second car name is an example of a "second name".

For example, in a first country or first region, if a vehicle is given a name that can be interpreted as "A" as the first car name, the first car name is used in the second country or second region. However, it is often interpreted with a different meaning of "B". In consideration of this, vehicle manufacturers may 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 where the host vehicle M is present, the display control device 100 automatically displays an appropriate vehicle name corresponding to the country or region on the display unit 102 . As a result, for example, people outside the vehicle who are curious about the vehicle name of the own vehicle M can be made aware of the vehicle name that is appropriately named according to the country or region. Also, for example, if the vehicle is sold in a different country or region, it eliminates work such as reprogramming to change the display content or re-installing the content at the sales base in each country or region. can do.

These devices may also be connected to each other by wireless communication. The configuration shown in FIG. 5 is merely an example, and 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 configuration described above. The camera 108 is a camera that captures an image of the inside of the own vehicle M. As shown in FIG. The camera 108 is, for example, a digital camera using a solid-state imaging device such as a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor). When the camera 108 captures an image of the interior of the vehicle M, the camera 108 generates image data and outputs the image data to the control unit 120 . The image data may be, for example, a still image or a moving image (video) in which still images are continuous in time series.

In addition to the configuration described above, the control unit 120 according to the second embodiment further includes an in-vehicle monitoring unit 130 . The vehicle interior monitoring unit 130 monitors the vehicle interior of the 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 section 240 and a charge monitoring control section 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. The secondary battery 210 discharges the stored electric power under the control of the charge monitoring control unit 250 and supplies the discharged electric power to the electric motor that is the driving source of the own vehicle M.

The sensors 220 include, for example, current sensors, voltage sensors, temperature sensors, and the like. The sensor 220 detects, for example, the current charged to the secondary battery 210 or the current discharged from the secondary battery 210, or detects the voltage applied to the secondary battery 210 or the temperature of the secondary battery 210. do. Sensor 220 outputs the detected current value, voltage value, temperature, and the like to charge monitoring control unit 250 .

The storage unit 240 is implemented by an HDD, flash memory, EEPROM, ROM (Read Only Memory), RAM, or the like. The storage unit 240 stores, for example, programs referred to by the processor.

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

The charge monitoring control unit 250 calculates the charging rate of the secondary battery 210 based on the detection result of the sensor 220 . The charging rate may be, for example, SOC (State Of Charge) obtained by dividing the remaining capacity by the full charge capacity. The charging monitoring control unit 250 charges the secondary battery 210 with 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 charging rate. Discharge the stored power.

[Processing flow of display control system]
The flow of a series of processes of the display control system 1 according to the second embodiment will be described below using a flowchart. FIG. 6 is a flow chart showing a series of processes 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 a charging spot. A 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 charge plug 302 of the charger 300 is electrically connected to the charge port 230 of the own vehicle M (step S200). When the charging plug 302 is electrically connected to the charging plug 302, the secondary battery 210 is charged with the power supplied from the charging plug 302 (step S202).

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

After calculating the required charging time, the charging monitoring control unit 250 transmits information representing the calculated time to the display control device 100 via the internal bus BS. Upon receiving 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 charging rate of the secondary battery 210 and determines whether or not the secondary battery 210 is fully charged (step S208).

If the secondary battery 210 is not fully charged, the charging monitoring control unit 250 returns the process to S204 and recalculates the required charging time based on the detection result of the sensor 220 . Thereby, the required 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 charging 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. Charging completion information indicating that the charging has been completed is transmitted to the display control device 100 via the internal bus BS.

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

When a user is in the vehicle M, the vehicle interior 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 an image or video imaged by the camera 108, identifies an eye region from the feature information of the user's face, and based on the color information of the identified eye region. The display area (area on the image) of the eyeball portion in the image is estimated. Then, if the estimated display area of the eyeball portion is hidden by the eyelids and becomes equal to or less than a predetermined value and this state continues for a predetermined time or longer, the vehicle interior monitoring unit 130 determines that the eyelids are closed. 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 greater than a predetermined value. In-vehicle monitoring unit 130 determines that the eyelids are open when the display area of the eyeball portion is larger than a predetermined value. 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 according to the presence or absence of the user's motion. Specifically, the in-vehicle monitoring unit 130 analyzes the images and videos captured by the camera 108 to identify body parts such as the user's upper body, arms, and hands, and determines whether the identified parts are located within a predetermined period of time. It is determined whether or not the motion has occurred more than the fixed amount. For example, if the specified part moves more than a predetermined amount within a predetermined time, the in-vehicle monitoring unit 130 determines that there is a movement of the user's body. determine that there is no The in-vehicle monitoring unit 130 determines that the user is awake if there is physical motion of the user, and determines that the user is not awake if there is no physical motion of the user.

In addition, 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 whether or not the user is moving. Whether or not the user is awake may be determined based on the detection result of a load sensor (not shown) provided in each seat provided in the vehicle or the detection result of a biosensor (not shown). A load sensor is a sensor that detects a load applied to a seat. The biosensor detects biometric information such as heart rate, body temperature, and voice, for example. The biosensor may be a wearable device that can communicate with the display control device 100, or may be a device installed on the steering wheel of the own vehicle M, an instrument panel, or the like.

Specifically, when the amount of change in the load detected by the load sensor changes by a predetermined amount or more within a predetermined period of time, the in-vehicle monitoring unit 130 determines that the user is awake because the user is moving. 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, the in-vehicle monitoring unit 130 detects whether the heart rate detected as biological information by the biosensor has decreased to about the heart rate during sleep, or the detected body temperature has decreased to about the body temperature during sleep, If the user's snoring is detected, it may be determined that the user is not awake.

When the user is in the vehicle M and the user is awake, the vehicle interior monitoring unit 130 terminates the processing of this flowchart.

On the other hand, when the user is not in the vehicle M, or when the user is in the vehicle M but the user is not awake, the display control unit 126 The display unit 102 displays the content related to the person's contact information (step S216). This completes 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. Assume that charging plug 302 connected to charger 300 via cable 304 is connected to own vehicle M and charging of secondary battery 210 is started, as in the illustrated example. In general, the charge capacity (battery capacity) of the secondary battery 210 mounted on an electric vehicle is large, ranging from several tens [kWh] to several hundred [kWh], and charging tends to take a long time. Therefore, the user may take a nap in the vehicle or go out of the vehicle until 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, if the user is not in the vehicle M when the charging of the secondary battery 210 is completed, or if the user is in the vehicle M, the display control unit 126 If 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 for push notification, and certificate is coded (encrypted or coded).

Thus, by displaying the contact information of the user of the own vehicle M as a two-dimensional code MK, the user's contact information can be communicated to people around the own vehicle M while keeping the user's personal information confidential. can be done. For example, when a user of another vehicle scheduled to use the charger 300 next starts a dedicated application installed in a mobile phone or the like and reads the two-dimensional code MK with a camera, From the telephone, the telephone is connected to the mobile phone of the user of the own vehicle M, or an e-mail or push notification is transmitted. As a result, the user inside the vehicle M can be awakened, and the user outside the vehicle can be urged to return to the vehicle M. In addition, since the display unit 102 displays not only the character information but also the two-dimensional code MK, it is possible to notify the user's contact information even to a person such as a foreigner who speaks a different language.

In the above description of the second embodiment, 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 charging monitoring device 200 may continue charging up to a target charging rate preset by the user, and stop charging when the secondary battery 210 is charged up to the target charging rate. Further, the charge monitoring device 200 may continue charging until a predetermined time set in advance by the user elapses, and stop charging when the set predetermined time elapses. While the charging rate of the secondary battery 210 reaches the target charging rate, the display control device 100 is controlled when the charging of the secondary battery 210 is performed and charging is stopped, or when charging of the secondary battery 210 is stopped. When the charging is stopped after the predetermined period of time, the processes of S212 and S214 are performed to display the content related to the user's contact information on the display unit 102 .

Further, in the above description of the second embodiment, the display control device 100 displays the required charging time on the display unit 102 while the secondary battery 210 is being charged. can't For example, while the secondary battery 210 is being charged, the display control device 100 may cause the display unit 102 to display content related to the user's contact information instead of or in addition to the required charging time. .

Also, in the above description of the second embodiment, the display control device 100 displays content related to the user's contact information on the display unit 102, but the present invention is not limited to this. For example, the communication control unit 128 of the display control device 100 controls the communication unit 106 to transmit content related to the user's contact information to a business operator (e.g., an employee of a charging spot, etc.) who is qualified to use the charger 300. ) may be sent to the terminal device that can use it. As a result, for example, an employee of the charging spot can contact the user of own vehicle M instead of the user of another vehicle who is scheduled to use charger 300 next.
