DETAILED DESCRIPTION Exemplary embodiments of a display control device, a terminal, a display control system, and a display control method according to the present invention are explained in detail below with reference to the accompanying drawings. In the display control described below, based on the current location of the moving body, the destination, and battery information, it is calculated whether or not it is possible to continue to the destination, and the user is notified in an easy-to-understand manner. The notification can be easily determined by the user using a color or the like that is different depending on whether the destination can be reached or not. In addition, the remaining battery level or the insufficient battery level is also displayed for the travel to the destination.

(Embodiment 1)
FIG. 1 is a block diagram of a functional configuration of the display control system according to the first embodiment. In the configuration example shown in FIG. 1, a mobile body (vehicle) is equipped with a terminal 120 and exchanges information with a server 100 provided outside the mobile body (terminal) 120 by communication.

The server 100 includes a receiving unit 101, a calculating unit 102, a determining unit 103, a display control unit 104, and a transmitting unit 105. Further, the terminal 120 includes an acquisition unit 121, a transmission unit 122, a reception unit 123, and a display unit 124.

(Terminal configuration)
The acquisition unit 121 of the terminal 120 acquires current location information, destination information, and battery information. The current location information and the destination information are each location information, for example, latitude and longitude, and are acquired by GPS or the like. The battery information detects the maximum charge capacity of the battery of the mobile unit and the current remaining battery level. These pieces of information can be obtained from an in-vehicle communication network (hereinafter simply referred to as CAN) that operates through a communication protocol such as CAN (Controller Area Network) via an electronic control unit (ECU) in the moving body. it can.

The transmission unit 122 transmits the current location information, destination information, and battery information acquired by the acquisition unit 121 to the server 100 via the communication network 131. The receiving unit 123 receives battery running information from the server 100 via the communication network 131. The battery driving information is whether or not it is possible to continue to the destination with the current remaining battery level, the remaining battery level when it is possible to continue, or the insufficient battery level when it is impossible to continue, etc. Consists of information.

The battery running information received via the receiving unit 123 is displayed on the display unit 124, and the user can continue to the destination according to the displayed content, and the remaining battery level when the user can continue traveling, or When cruising is impossible, the amount of battery shortage and other information can be obtained.

(Server configuration)
The server receiving unit 101 receives the current location information, the destination information, and the battery information transmitted from the transmitting unit 122 of the terminal 120, and outputs them to the calculating unit 102. Based on the current location information, the destination information, and the battery information, the calculation unit 102 calculates a cruising distance with the current remaining battery level. At this time, the calculation unit 102 uses the map information to search for a plurality of routes in a range that can be navigated from the current location to the destination direction.

The determination unit 103 determines whether the cruising distance calculated by the calculation unit 102 reaches the destination. As a result of the determination, when the cruising distance reaches the destination, the battery amount consumed up to the destination and the remaining battery level after reaching the destination are output together. If the cruising distance cannot reach the destination, the point when the battery is completely consumed and the shortage of battery from this point to the destination are output together.

The display control unit 104 outputs a display signal to be displayed with different display contents depending on whether the reachable distance reaches the destination as a result of the determination by the determination unit 103. If it is reachable, a bar graph is displayed to show that it is reachable at a glance. At this time, the bar graph outputs a display signal divided by the amount of battery consumed up to the destination and the remaining amount of the battery after reaching the destination.

On the other hand, if it is unreachable, the user is notified intuitively that it is unreachable by means of a bar graph display using a color or the like that can be seen at a glance. At this time, the bar graph outputs a display signal in which the point when the battery is completely consumed and the insufficient amount of battery from this point to the destination are separated.

The transmission unit 105 transmits the display signal output from the display control unit 104 to the terminal 120.
Thus, the terminal 120 can receive a display signal whose display is controlled on the server 100 side, and display and output it on the display unit 124.

(About display control processing contents)
FIG. 2 is a flowchart showing a procedure of display control processing by the display control system. First, the acquisition unit 121 of the terminal 120 acquires current location information and destination information set in the vehicle (step S201). Next, vehicle battery information is acquired (step S202). This battery information is the maximum charge capacity of the battery and the current remaining battery level.

The information acquired in step S201 and step S202 is transmitted from the transmission unit 122 of the terminal 120 to the server 100 via the communication network 131. The receiving unit 101 of the server 100 receives information transmitted from the terminal 120. The calculation unit 102 calculates a cruising range based on the received current location information, destination information, and battery information (step S203).

At this time, the calculation unit 102 searches for a route to the destination of the moving object based on the link information included in the acquired map data. A link is a section divided by points where road types and speed bands change, points where regions change such as boundaries of prefectures and municipalities, and the like. Link information is set for each link. The link information includes the link position and altitude, the link distance, the moving time of the moving object, and the like.

Specifically, for example, the calculation unit 102 searches for a plurality of one route formed by connecting adjacent links from the departure point of the moving body to the destination by variously changing the link connection. At this time, the link information of each link may be used as a weight during route search. It is possible to perform route search with priority on time, distance, and energy consumption according to weighting.

For example, when the route search condition is time-prioritized, one route configured by connecting the links that can be moved in the shortest time is searched. In addition, the link cost from the starting point of the moving object to the destination is integrated for each link information. Then, the route search is performed using the link information in each link as the link cost. The weight of each link information may be changed according to the integrated cost of each link information.

Next, the determination unit 103 determines whether the cruising distance calculated by the calculation unit 102 is cruising to the destination (step S204). If the result of determination by the determination unit 103 is that it is possible to continue to the destination (step S204: Yes), the display control unit 104 performs display output indicating that it can be reached (first display form). Further, the battery amount consumed up to the destination and the remaining amount of the battery after reaching the destination are output together (step S205), and the series of processes is terminated.

On the other hand, if the result of determination by the determination unit 103 is that it is not possible to continue to the destination (step S204: No), the display control unit 104 performs display output indicating that the destination cannot be reached (second display mode) ). Further, the point when the battery is completely consumed and the insufficient amount of battery from this point to the destination are output together (step S206), and the series of processing ends.

The display output by the display control unit 104 is received by the reception unit 123 of the terminal 120 via the transmission unit 105, displayed on the display unit 124, and notified to the user.

As described above, the display control system according to the embodiment determines whether or not the moving body can continue to the destination with the current battery, and the display content varies depending on whether or not the mobile body can continue. Is displayed to the user, the user can intuitively determine whether or not it is possible to continue to the destination. In addition, if the cruising is possible, the remaining battery level is displayed together, so that it is possible to travel while recognizing a sufficient state in advance. If the cruising is impossible, it is displayed how much the battery is insufficient, and thus it is possible to navigate considering the shortage of the battery.

(Hardware configuration of server 100)
Next, the hardware configuration of the server 100 will be described. FIG. 3 is a block diagram illustrating a hardware configuration of the server. In FIG. 3, the server 100 includes a CPU 301, ROM 302, RAM 303, magnetic disk drive 304, magnetic disk 305, optical disk drive 306, optical disk 307, input device 311, and communication I / F 315. Each component 301 to 315 is connected by a bus 320.

First, the CPU 301 governs overall control of the server 100. The ROM 302 records programs such as the display control described above. The RAM 303 is used as a work area for the CPU 301. That is, the CPU 301 controls the entire server 100 by executing various programs recorded in the ROM 302 while using the RAM 303 as a work area.

The magnetic disk drive 304 controls the reading / writing of the data with respect to the magnetic disk 305 according to control of CPU301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, an HD (hard disk) or an FD (flexible disk) can be used.

The optical disk drive 306 controls reading / writing of data with respect to the optical disk 307 according to the control of the CPU 301. The optical disk 307 is a detachable recording medium from which data is read according to the control of the optical disk drive 306. As the optical disc 307, a writable recording medium can be used. In addition to the optical disk 307, an MO, a memory card, or the like can be used as a removable recording medium.

Yes.

The input device 311 includes a remote controller, a keyboard, a touch panel, and the like provided with a plurality of keys for inputting characters, numerical values, various instructions, and the like. The input device 311 may be realized by any one form of a remote control, a keyboard, and a touch panel, but can also be realized by a plurality of forms.

The communication I / F 315 is connected to a network via a wire or wirelessly, and functions as an interface between the server 100 and the CPU 301. The communication network functioning as a network includes a public line network, a mobile phone network, DSRC (Dedicated Short Range Communication), LAN, WAN, and the like. The communication I / F 315 is, for example, a public line connection module.

The acquisition unit 121, the calculation unit 102, the determination unit 103, and the display control unit 104 illustrated in FIG. 1 are set by the CPU 301 using predetermined programs and data recorded in the ROM 302, the RAM 303, the magnetic disk 305, the optical disk 307, and the like. The function is realized by executing the program.

(Hardware configuration of terminal 120)
Similar to the hardware configuration of the server 100 shown in FIG. 3, the hardware configuration of the terminal 120 includes a CPU, a ROM, and a RAM. The CPU uses various programs recorded in the ROM while using the RAM as a work area. By executing this, the entire terminal 120 is controlled.

Also, it has GPS function as various sensors, and can acquire the current location and location information of the destination. If the terminal 120 is configured to have a map function, the location information of the destination can be easily acquired by displaying the vicinity of the destination on the map. Moreover, as various sensors, the maximum charge capacity of the battery of the moving body and the current battery remaining amount are acquired. In addition, a communication I / F is provided to exchange information with the external server 100 by communication.

In addition, the terminal 120 includes an input device, and various operation inputs are possible. In addition, various types of information can be acquired by providing a magnetic disk drive, a magnetic disk, an optical disk drive, an optical disk, and the like.

Next, an example of display output will be described. FIG. 4 is a diagram illustrating a display example when cruising is possible. As a result of the determination by the determination unit 103, the display control unit 104 shows a display example in the case where it is possible to continue to the destination. In this case, on the display unit 124 of the terminal 120, a display output indicating that it is reachable is made.

As shown in FIG. 4, this display is displayed as a bar graph (bar graph or dot). The length of the bar graph is displayed as the maximum charge capacity L1 of the battery. Further, the current charging capacity L2 is displayed with a predetermined length from one end (the left end in the figure). The left end of the figure corresponds to the current location a. It is possible to know how much the battery can be charged by the current charge capacity L2 with respect to the maximum charge capacity L1.

Also, of the current charging capacity L2, the expected battery consumption L3 consumed for navigation to the destination b is displayed in a predetermined length from the current location a to the destination b. From the position of the destination b, the remaining amount L4 of the battery is displayed in a predetermined length between the travelable distance d. Since the display shown in FIG. 4 is a display example when the cruising to the destination is possible, the predicted consumption L3 displayed as a bar graph and the remaining battery charge L4 can both be crushed to the destination b. For example, a color indicating that there is a safe cruising, such as light blue for the predicted consumption L3 and green for the remaining battery charge L4, is displayed.

This allows the user to grasp and recognize at a glance with confidence that the displayed color indicates that the current charge capacity L2 can continue to the destination b. In addition, even after arriving at the destination b, it is possible to grasp at a glance how much the remaining amount of the battery is by displaying the length of the remaining amount L4 of the battery.

FIG. 5 is a diagram showing a display example when cruising is impossible. As a result of the determination by the determination unit 103, a display example when it is not possible to continue to the destination is shown. In this case, a display output indicating that the terminal 120 cannot be reached is output on the display unit 124 of the terminal 120.

As shown in FIG. 5, even when the cruising is impossible, the length of the bar graph is the maximum charge capacity L1 of the battery. Further, the current charging capacity L2 is displayed with a predetermined length from one end (the left end in the figure). The left end of the figure corresponds to the current location a. Further, the other end (right end in the figure) of the current charging capacity L2 is the travelable distance d. It is possible to know how much the battery can be charged by the current charge capacity L2 with respect to the maximum charge capacity L1.

Then, for the navigation to the destination b, the section from the current charging capacity L2 (travelable distance d) to the destination (right side) destination b is displayed with a predetermined length as being a battery shortage L5. In the display shown in FIG. 5, the current charging capacity L2 displayed as a bar graph is displayed using a color indicating that safe cruising is possible, such as light blue.

However, since it is a display example when it is not possible to continue to the destination, the battery shortage L5 is insufficient for navigation to the destination b. It is displayed using a conspicuous color that can easily indicate that it is present.

Thereby, the user can immediately grasp and recognize that it is impossible to continue to the destination b with the current charging capacity L2 by the displayed color. In addition, it is possible to grasp at a glance how much battery capacity is required for the cruising to the destination b by displaying the length of the battery shortage L5. As a result, the user can depart in a state where the user knows in advance that the battery needs to be charged during cruising to the destination. The above is the image display based on the first display control signal.

Also, the point e in the figure indicates the location of the charging station, which is a replenishing device for replenishing the battery. The location of the charging station is acquired based on the map information referred to by the supplementary position acquisition means when searching for a route from the current location to the destination. The server 100 displays the acquired location of the charging station corresponding to the distance of the section from the current location a to the destination b on the bar graph. This image is displayed based on the second display control signal generated together with the first display control signal described above. Thus, the user can obtain information on the position e of the charging station, know that the cruising to the destination b is possible, and can start with peace of mind.

In the display example of FIG. 5, the position e of the charging station is displayed only in the area of the current charging capacity L2. According to this display, it becomes possible to prompt charging at a charging stand that can be charged with the current remaining battery level. Even if the current charging capacity L2 is extended by charging at the charging station, the position e of the charging station within the range of the bar of the current charging capacity L2 up to the destination b is displayed. As a result, the position e of the charging station can always be grasped, information relating to the charging after the next time can be obtained, and the destination b can be traveled with peace of mind.

Next, a display example when no destination is set will be described. FIG. 6 is a diagram illustrating a display example when cruising is possible when a destination is not set.

When the destination is not set and the home position is set, the calculation unit 102 sets the home position as the destination, and the determination unit 103 determines whether or not it is possible to continue to this home position. For this reason, when the destination cannot be acquired, the calculation unit 102 requests the acquisition unit 121 to set and receive the home position. The home position is a place where the mobile body returns such as a garage at home, and the latitude and longitude of the home position may be set in advance in the terminal 120.

The length of the bar graph is displayed as the maximum charge capacity L1 of the battery, and the current charge capacity L2 is displayed with a predetermined length from one end (the left end in the figure). The left end of the figure corresponds to the current location a. It is possible to know how much the battery can be charged by the current charge capacity L2 with respect to the maximum charge capacity L1.

Then, of the current charging capacity L2, the expected battery consumption L3 consumed for navigation to the home position c is displayed in a predetermined length from the current location a to the home position c. From the position of the home position c, the remaining amount L4 of the battery is displayed in a predetermined length up to the travelable distance d. Since the display shown in FIG. 6 is a display example when the cruising to the destination is possible, both the expected consumption L3 displayed as a bar graph and the remaining battery charge L4 can be crushed to the home position c. For example, a color indicating that there is a safe cruising, such as light blue for the predicted consumption L3 and green for the remaining battery charge L4, is displayed.

As a result, when the destination b is not set when returning home, the home position c is set as the destination, so that the user is displayed that the current charging capacity L2 can continue to the home position c. You will be able to grasp and recognize at a glance with confidence at a glance. The home position c usually has a charging facility and can be charged at the home position c. In addition, even after arriving at the home position c, it is possible to grasp at a glance how much the remaining amount of the battery is by displaying the length of the remaining amount L4 of the battery.

FIG. 7 is a diagram showing a display example when cruising is impossible. As a result of the determination by the determination unit 103, a display example when it is impossible to continue to the home position is shown. In this case, a display output indicating that the terminal 120 cannot be reached is output on the display unit 124 of the terminal 120.

As shown in FIG. 7, even when the cruising is impossible, the length of the bar graph is the maximum charge capacity L1 of the battery. Further, the current charging capacity L2 is displayed with a predetermined length from one end (the left end in the figure). The left end of the figure corresponds to the current location a. Further, the other end (right end in the figure) of the current charging capacity L2 is the travelable distance d. It is possible to know how much the battery can be charged by the current charge capacity L2 with respect to the maximum charge capacity L1.

Then, for the navigation to the home position c, the section from the current charging capacity L2 (travelable distance d) to the previous (right side) home position c is displayed with a predetermined length as the battery shortage L5. Among the displays shown in FIG. 7, the current charge capacity L2 displayed as a bar graph is displayed using a color indicating that safe cruising is possible, such as light blue.

However, since it is a display example when it is not possible to continue to the destination, the battery shortage L5 is insufficient for navigation to the home position c. It is displayed using a color that easily informs you.

Thereby, the user can immediately grasp and recognize from the displayed color that it is impossible to continue to the home position c with the current charging capacity L2. In addition, it is possible to grasp at a glance how much battery capacity is required for the cruising to the home position c by displaying the length of the battery shortage L5. As a result, the user can depart in a state where the user knows in advance that the battery needs to be charged during cruising to the destination.

Also in this display example, the point e in the figure indicates the location of the charging station as a point. The location of the charging station is displayed in correspondence with the distance of the section from the current location a to the home position c on the bar graph. As a result, the user can obtain information on the position e of the charging station, know that the cruising to the home position c is possible, and can start with peace of mind. Further, in the current charge capacity L2 region, it is possible to travel safely to the home position c by the displayed position e of the charging stand.

Next, a method for calculating the length of the barcraft described above will be described. This will be described based on the example shown in FIG. The overall length (100%) of the bar graph is set based on the maximum charge capacity L1. Further, the maximum charge amount P1, the current charge capacity P2, and the predicted power consumption P3 are assumed.
Thereby, the length L3 = L1 × P3 / P1 of the bar to the destination b
It can be obtained based on the current charging capacity L2 (navigable) length L2 = L1 × P2 / P1.

Next, an example of displaying the above bar graph together with route guidance information will be described. FIG. 8 is a diagram illustrating a display example of a bar graph relating to cruising along with route guidance information. The route guidance information is displayed on the display unit 124 of the terminal 120 as a route searched by the terminal 120 or the server 100 based on the current location and destination information. In this case, for example, if the terminal 120 has a navigation function and has a route search and route guidance function, it is not necessary to transmit the route search and route guidance information to the server 100.

Then, the terminal 120 causes the display unit 124 to display the route search and route guidance information 800 generated inside the terminal 120. These pieces of information 800 include the current location 801, the distance 802 to the destination, the required time 803, the arrival time 804, the destination 805, the traveling direction 806 at the next intersection, and the traveling directions 807 at the subsequent intersections shown in FIG. Etc.

Then, the server 100 executes generation of the display signal related to the bar graph display described above, and the terminal 120 displays the display output from the server 100 as a bar graph 810 so as to be superimposed on a part of the information 800. Even in the case of overlapping, an empty display area for the information 800 is provided in advance or is displayed at an empty place. As a result, the bar graph 810 can be viewed together with the route search and route guidance information 800. As shown in the figure, the bar graph 810 does not take up space in the lower part of the display area and can efficiently display a plurality of information in a small space, so that even if the display area of the display unit 124 is small, the bar graph 810 is visible. Can increase the sex. Note that the bar graph 810 shown in FIG. 8 is displayed when cruising is possible, but is also displayed at the same location when cruising is impossible.
