<< Operation >>
Next, three typical examples of the processing of the vehicle management system 1 will be described in detail with reference to FIGS. 3 to 5. In addition, although the operation subject is assumed to be the vehicle 10 and the base station 20, respectively, the processing of the vehicle 10 is actually performed by the control unit 14, and the processing of the base station 20 is performed by the control unit 212 of the management server 21. It is.
<Communication area 1>
With reference to FIG. 3, processing when the vehicle 10 always stays in the communication area and transmits the GPS position information from the vehicle 10 to the base station 20 will be described (see FIGS. 1 and 2 as appropriate). ). FIG. 3 is a flowchart showing processing of vehicle 10 and base station 20 at that time.
First, the vehicle 10 acquires the position information of the own vehicle from the GPS 70 (S11), and transmits the position information to the base station 20 (S13). The base station 20 acquires the communication status of the wide area from the communication line company 40 before receiving the GPS position information transmitted from the vehicle 10 in S13 (S12), but after receiving the position information from S13, the S12 May be executed.

  Subsequently, the base station 20 extracts only the communication status of the wide area, the traffic information of the wide area obtained from the information provider, the disaster status, and the construction status of the area where the vehicle 10 stays, and extracts them. It transmits to the vehicle 10 (S14). The vehicle 10 displays the received communication status, traffic jam status, and the like on the display unit 15 which is a navigation screen (S15). An example of the display unit 15 is as shown in FIG.

  In this way, the vehicle 10 progresses so as not to leave the communication area due to the communication status and traffic jam information in the surrounding area of the own vehicle, the fuel supply station 30 displayed on the map 151 of the display unit 15 in FIG. It is possible to know the direction, the congested road, the location of the fuel supply station 30, and the like, and when the fuel is reduced, the fuel can be appropriately supplied.

<Communication area 2>
Next, a process when the vehicle 10 always stays in the communication area and the GPS position information is not transmitted from the vehicle 10 to the base station 20 will be described with reference to FIG. FIG. 2). FIG. 4 is a flowchart showing processing of vehicle 10 and base station 20 at that time.
First, the vehicle 10 acquires the position information of the own vehicle from the GPS 70 (S21). Further, the base station 20 acquires the communication status of the wide area from the communication line company 40 (S22), and transmits it to the vehicle 10 together with the traffic information, disaster status, and construction status of the wide area obtained from the information providing company ( S23).
The vehicle 10 uses the position information of the own vehicle obtained in S21 to extract the communication situation and traffic situation in the surrounding area from the received communication situation and traffic situation in the wide area (S24), and navigates them. It displays on the display part 15 which is a screen (S25). An example of the display unit 15 is as shown in FIG.

In this way, the vehicle 10 progresses so as not to leave the communication area due to the communication status and traffic jam information in the surrounding area of the own vehicle, the fuel supply station 30 displayed on the map 151 of the display unit 15 in FIG. It is possible to know the direction, the congested road, the location of the fuel supply station 30, and the like, and when the fuel is reduced, the fuel can be appropriately supplied.
The information is narrowed down in S24 in order to reduce the load on the control unit 14 and the storage unit 13 of the vehicle 10, and if it is not necessary to reduce the load, S24 is omitted. May be.

<When leaving the communication area>
A process when the vehicle 10 leaves the communication area will be described with reference to FIG. 5 (see FIGS. 1 and 2 as appropriate). FIG. 5 is a flowchart showing processing of vehicle 10 and base station 20 at that time.
First, the vehicle 10 acquires the position information of the own vehicle from the GPS 70 (S31), and transmits the position information and the remaining fuel information of the own vehicle to the base station 20 (S34). It is assumed that the vehicle 10 stays in the communication area until the completion of S34 and may leave the communication area thereafter.

Before receiving the GPS position information transmitted from the vehicle 10 in S34, the base station 20 obtains the reservation status and the storage amount information from the fuel supply station 30 (S32), and receives a wide area from the communication line company 40. The communication status is acquired (S33). Note that the base station 20 may execute S32 and S33 after receiving S34.
Next, the base station 20 calculates an appropriate fuel supply station 30 from the GPS position information of the vehicle 10, the remaining fuel information, the reservation status / storage amount of the fuel supply station 30, etc. (S35), and the fuel supply station 30 The communication status of the surrounding area of the vehicle 10 is transmitted to the vehicle 10 (S36).
For the calculation of the fuel supply station 30, a disaster situation, a construction situation, etc. provided from an information provider (not shown) may be used as judgment materials. Further, if the fuel supply station 30 is close to the current location of the vehicle 10 to some extent, even if the hydrogen gas storage amount is small or the reservation is large, it is calculated as a candidate. The fuel supply station 30 having a small number or a large number of reservations may be excluded from candidates.

Hereinafter, processing on the vehicle 10 side after S36 will be described. The vehicle 10 determines whether or not there is a reply from the base station 20 within a predetermined time (for example, 1 minute) from each information transmission in S34 (S37). If the vehicle 10 stays in the communication area when the base station 20 transmits each piece of information in S36, the vehicle 10 is transmitted from the base station 20 in S36 within a predetermined time from S34. Information can be received (S37 → Y), and the received communication status and candidates for the fuel supply station 30 are displayed on the display unit 15 which is a navigation screen.
As a result, the passenger can know the positions of the neighboring fuel supply stations 30, the amount of hydrogen gas stored in each fuel supply station 30, and the reservation status. The desired fuel supply station 30 can be freely selected, such as the closest fuel supply station 30 or the fuel supply station 30 with a large amount of hydrogen gas stored even a little further away. Further, if the traffic congestion status, disaster status, construction status, and the like are also displayed on the display unit 15, it is easy to access each fuel supply station 30 and it is more convenient.

  If the vehicle 10 has left the communication area when the base station 20 transmits each information at S36, the vehicle 10 receives each information transmitted from the base station 20 at S36 within a predetermined time from S34. In other words, S37 becomes N, and the vehicle 10 predicts the travel route to the destination from information such as the destination and traffic conditions that are input in advance, and calculates the travelable distance from the remaining fuel. Also, the latest communication status received from the base station 20 is searched (S39).

Subsequently, the vehicle 10 determines whether or not the own vehicle can reach the destination with the remaining fuel from each data obtained in S39 (S40). When it is determined that it is reachable (S40 → Y), the latest communication status and the like are displayed on the display unit 15 which is a navigation screen (S41). As a result, the passenger can freely select whether to go to the destination as it is, to return to the communication area, or to refuel to a nearby fuel supply station 30 just in case. be able to.
When the vehicle 10 is out of the communication area, the latest hydrogen gas storage amount and reservation status of each fuel supply station 30 that the base station 20 is trying to transmit in S36 is displayed on the display unit 15 of the vehicle 10. Although it is not possible to do so, the map 151 of the display unit 15 shows the position of the fuel supply station 30 and the latest information of each fuel supply station 30 received by the vehicle 10 from the base station 20 (hydrogen gas storage amount and reservation status). Is displayed so that the passenger can see it, select the desired fuel supply station 30, and go there.
In S40, it is determined whether or not the vehicle 10 can reach the destination with the remaining fuel, but it may be determined based on another criterion such as whether or not the remaining fuel amount is greater than a predetermined value. Good.

  Returning to the flowchart of FIG. 5, when it is determined that the vehicle 10 cannot reach the destination with the remaining fuel (S40 → N), the latest communication status is displayed on the map 151 of the display unit 15 which is a navigation screen, Further, a warning display for returning to the communication area for the passenger is displayed on the display 85 of the data 152 of the display unit 15, and the vehicle 10 is guided into the communication area (S42). Note that when displaying to the passenger that the vehicle is to return to the communication area, the map 151 of the display unit 15 is congested on an appropriate road to enter the communication area (the weak signal area 99 or the good area 98) from the current location. It is also possible to calculate and display based on information or the like.

Subsequently, the processing on the base station 20 side after S36 will be described. When the transmission of each information in S36 is successful (that is, when the vehicle 10 stays in the communication area: S43 → Y), the base station 20 ends the process.
When transmission of each information in S36 is not successful (that is, when the vehicle 10 is out of the communication area: S43 → N), the base station 20 determines the remaining fuel of the vehicle 10 transmitted by the vehicle 10 in S34. It is determined whether or not the amount is smaller than a predetermined amount (S44). This is for determining the subsequent response of the base station 20 according to the amount of remaining fuel in the vehicle 10, and the predetermined amount is, for example, from the point where communication is interrupted to the fuel supply station 30 at the shortest distance. 10 may be the amount of fuel that can travel, or may be a predetermined amount of fuel (such as a predetermined pressure).

When the remaining fuel of the vehicle 10 is not less than the predetermined amount (S44 → Y), the base station 20 determines that the remaining amount of the vehicle 10 is relatively large and no action is required immediately. Wait until the communication state is restored (S45). Thereby, it can avoid that the base station 20 performs a process with low necessity.
When the remaining fuel of the vehicle 10 is less than a predetermined amount (S44 → N), the base station 20 has a fuel supply station 30 in the vicinity of the vehicle 10 or in the traveling direction from the destination or traveling direction of the vehicle 10. Whether or not (S46).

When the fuel supply station 30 exists in the vicinity of the vehicle 10 or in the traveling direction (S46 → Y), the base station 20 makes a reservation for refueling of the fuel supply station 30 (S47), and the communication state is recovered. Is notified to the vehicle 10. As a result, the vehicle 10 can quickly refuel when the communication state is recovered.
When the fuel supply station 30 does not exist in the vicinity of the vehicle 10 or in the traveling direction (S46 → N), the base station 20 provides a follow service (fuel supply by tank lorry, transport by tow truck, etc.) as a countermeasure for running out of fuel of the vehicle 10. Arrange (S48), and notify the vehicle 10 that the follow service has been arranged as necessary when the communication state is restored. Thereby, even if it is a case where the vehicle 10 runs out of fuel, the appropriate response | compatibility can be performed rapidly.

As described above, according to the vehicle management system 1 of the present embodiment, when the vehicle 10 is out of the communication area, the vehicle 10 communicates with the display unit 15 when there is no remaining fuel, such as when the vehicle 10 cannot reach the destination with the remaining fuel. By displaying the indication of returning to the area, the passenger knows that it is highly necessary to return to the communication area, and can appropriately determine the subsequent action, causing the vehicle 10 to run out of fuel outside the communication area. The possibility can be reduced.
In addition, when the vehicle 10 is out of the communication area, the base station 20 side waits for the recovery of the communication state when there is a margin in the remaining fuel of the vehicle 10 based on the latest remaining fuel information of the vehicle 10, By making reservations for the fuel supply station 30 or arranging a follow-up service when the remaining fuel in the vehicle 10 is not sufficient, it is possible to avoid running out of fuel in the vehicle 10 or to take measures when the fuel runs out only when necessary. Vehicle management can be realized.
