  Next, the filling number storage succession system of the fuel tank 15 will be described in detail.

  FIG. 4 is a block diagram of the vehicle filling number storage inheritance system according to the embodiment of the present invention.

  As shown in FIG. 4, the fuel cell vehicle 1 according to the present embodiment has a filling number storage succession system 69 as a fuel tank 15 that stores high-pressure hydrogen gas as a fuel and a plurality of control devices that perform different controls. Vehicle controller 19, inverter 18, power management device 17, secondary battery 16, and fuel cell 2.

  The filling number storage succession system 69 includes a main switch 71 connected to the vehicle controller 19, a lid open / close detection switch 72, and a pressure detection unit 73.

  The vehicle controller 19, the inverter 18, the power management device 17, the secondary battery 16, and the fuel cell 2 are connected via a CAN (Controller Area Network) so as to be capable of bidirectional communication. In addition, the vehicle controller 19, the inverter 18, the power management device 17, the secondary battery 16, and the fuel cell 2 have a storage device (not shown). The storage device of each device stores a control program for controlling each function. Further, a storage area for storing the number of times the fuel tank 15 is filled is secured in the storage device. The storage device is a nonvolatile memory including an EEPROM (Electrically Erasable Programmable Read-Only Memory).

  The main switch 71 is an input unit that instructs the vehicle controller 19 to start and stop the fuel cell vehicle 1. The main switch 71 is disposed at the center of the handle 45 or the front frame cover 42.

  The lid opening / closing detection switch 72 detects opening / closing of the fuel filling port lid 62.

  The pressure detector 73 detects the internal pressure of the fuel tank 15.

  Here, if only the vehicle controller 19 stores the number of times the fuel tank 15 is filled and the vehicle controller 19 is replaced due to a failure or the like, the number of times the fuel tank 15 is filled may become unknown.

  Therefore, at least one of the inverter 18, the power management device 17, the secondary battery 16, and the fuel cell 2 including the vehicle controller 19, that is, two control devices for convenience, when a predetermined start condition is satisfied, The number of fillings of the fuel tank 15 is compared with each other, and the storage area is rewritten with the number of fillings satisfying the selection condition among the plurality of filling times. This process is called a filling number succession process.

  The start condition is that the main switch 71 is turned on (that is, the start operation of the fuel cell vehicle 1). The starting condition is that the fuel filling port lid 62 is opened.

  The selection condition is a condition for selecting the largest number of fillings among a plurality of filling times. When it is assumed that two control devices, for example, the vehicle controller 19 and the inverter 18 store the number of fillings, the number of fillings stored in the replaced new vehicle controller 19 is 0, and the inverter 18 Is 101 times, the larger number of times 101 is selected.

  Next, the filling number succession processing of the filling number storage succession system 69 will be described in detail.

  In order to simplify the description, it is assumed that the storage area for storing the number of times the fuel tank 15 is filled is secured in the two control devices of the vehicle controller 19 and the inverter 18. In addition, the selection condition will be described as a condition for selecting a larger number of fillings out of the number of fillings stored in the vehicle controller 19 and the inverter 18.

  FIG. 5 is a flowchart of the filling number succession process when the vehicle is started in the filling number storage succession system according to the embodiment of the present invention.

  As shown in FIG. 5, in the filling number storage succession system 69 of the fuel cell vehicle 1 according to the present embodiment, when the main switch 71 is turned on, the fuel tank 15 stored in the vehicle controller 19 and the inverter 18 is stored. The number of fillings is compared with each other, and the storage area is rewritten with the number of fillings satisfying the selection condition of the two filling times.

  Specifically, when the main switch 71 is turned on (Yes in step S1), the vehicle controller 19 and the inverter 18 read the number of fillings from the respective storage areas (steps S2-1 and S2-2). Here, the filling number read from the storage area by the vehicle controller 19 is called a filling number Na, and the filling number read from the storage area by the inverter 18 is called a filling number Nb. Further, the process of the vehicle controller 19 is displayed as “−1”, and the process of the inverter 18 is displayed as “−2”.

  The vehicle controller 19 and the inverter 18 transmit the read filling counts Na and Nb in both directions (steps S3-1 and S3-2). The vehicle controller 19 receives the filling number Nb from the inverter 18, and the inverter 18 receives the filling number Na from the vehicle controller 19 (steps S4-1 and S4-2).

  The vehicle controller 19 compares the filling number Na stored by itself with the filling number Nb received from the inverter 18 (step S5-1), and when the filling number Na <the filling number Nb is satisfied (step S5). -1 Yes), the filling number Na is changed to the filling number Nb (step S6-1), and the process is terminated. If the number of times of filling Na <the number of times of filling Nb is not satisfied (No in step S5-1), the vehicle controller 19 bypasses step S6-1 and ends the process without changing the number of times of filling Na to the number of times of filling Nb. .

  On the other hand, the inverter 18 compares the filling number Nb stored in the inverter 18 with the filling number Na received from the vehicle controller 19 (step S5-2), and if the filling number Nb <the filling number Na holds ( In step S5-2, the filling number Nb is changed by the filling number Na (step S6-2), and the process is terminated. When the filling number Nb <the filling number Na is not established (No in step S5-2), the inverter 18 bypasses step S6-2 and ends the process without changing the filling number Nb with the filling number Na.

  FIG. 6 is a flowchart of the filling number succession process when the fuel filling port lid of the filling number storage succession system according to the embodiment of the present invention is opened.

  Note that the processing from step S2-1 to step S6-1 and step S2-2 to step S6-2 in FIG. 6 is the same as step S2-1 to step S6-1 and step S2-2 to step S6-2 in FIG. Since this process is the same as that in FIG.

  As shown in FIG. 6, in the fuel cell vehicle 1 according to the present embodiment, the filling number storage succession system 69 is a fuel tank stored in the vehicle controller 19 and the inverter 18 when the fuel filling port lid 62 is opened. The 15 filling times are compared with each other, and the storage area is rewritten with the filling number that satisfies the selection condition among the two filling times.

  Further, the vehicle controller 19 determines from the detection result of the pressure detection unit 73 that the fuel tank 15 has been filled with high-pressure hydrogen gas as fuel, and updates the number of fillings Na in the storage area. The control device excluding the vehicle controller 19, that is, the inverter 18, receives the updated filling number Na from the vehicle controller 19, and updates the storage area with the received filling number Na.

  Specifically, when the fuel filling port lid 62 is opened (Yes in Step S11), the vehicle controller 19 and the inverter 18 first process Step S2 to Step S6-1 and Step S6-2.

  Next, the vehicle controller 19 reconfirms that the fuel filling port lid 62 is opened (step S12). If the fuel filling port lid 62 is not opened, that is, is closed (No at Step S12), the vehicle controller 19 bypasses Step S13 to Step S18 without changing the filling number Nb with the filling number Na. Exit.

  On the other hand, if the fuel filling port lid 62 is opened (Yes in step S12), the vehicle controller 19 determines whether or not the fuel tank 15 is filled with high-pressure hydrogen gas as fuel from the detection result of the pressure detection unit 73. Is determined (step S13). For example, the vehicle controller 19 determines that the fuel tank 15 has been filled when the pressure in the fuel tank 15 has increased by 20% or more of the full filling pressure. Judge that it was not done. When the vehicle controller 19 determines that the fuel tank 15 is filled with high-pressure hydrogen gas as fuel (Yes in step S13), the vehicle controller 19 reads the number Na of times of filling from the storage area of the vehicle controller 19 and adds 1 to it (filling). Number of times Na = number of times of filling Na + 1) (step S14). Thereafter, the vehicle controller 19 transmits the updated number of fillings Na to the inverter 18 (step S15).

  On the other hand, when the inverter 18 receives the filling number Na from the vehicle controller 19 (step S16), the inverter 18 compares the filling number Nb stored therein with the filling number Na received from the vehicle controller 19 (step S17). When the number of times Nb <the number of times of filling Na is established (step S17 Yes), the number of times of filling Nb is changed to the number of times of filling Na (step S18), and the process is terminated. When the filling number Nb <the filling number Na is not established (No in step S17), the inverter 18 bypasses step S17 and ends the process without changing the filling number Nb with the filling number Na.

  Note that when the main switch 71 is turned off or the fuel filling port lid 62 is closed, the vehicle controller 19 and the inverter 18 rewrite the filling times Na and Nb in the respective storage areas. The write back processing of the filling times Na and Nb may be performed every time the filling times Na and Nb are changed in FIGS. 5 and 6, that is, every time step S 6-1 and step S 6-2.

  The selection condition may be a condition for selecting by majority from a plurality of filling times. When it is assumed that three control devices such as the vehicle controller 19, the inverter 18, and the power management device 17 store the number of fillings, the number of fillings stored in the replaced new vehicle controller 19 is zero. If the number of fillings stored in the inverter 18 is 101 and the number of fillings stored in the power management apparatus 17 is 101, the filling number 101 that occupies the majority is selected.

  When the selection condition is majority decision and all the control devices store different filling times, for example, the largest filling number may be selected, or it may be treated as an error, and visual information will be displayed to the passenger. Or voice information may be used.

  Further, when the selection condition is majority decision, and it is assumed that four or more control devices store the number of times of filling, and the number of times of filling (majority) occupying the majority antagonizes, for example, the most numerical value May be selected, or may be treated as an error and notified to the passenger by visual information or audio information. For example, with respect to the number of fillings stored in four control devices, the number of fillings stored in two replaced new control devices is 0, and two conventionally installed control devices store If the number of fillings is 101, the filling number 0 and 101 occupying the majority will antagonize, so the largest number of fillings may be selected, treated as an error, and the passenger You may alert | report by visual information and audio | voice information.

  The filling number succession processing of the filling number storage succession system 69 by majority decision will be described in detail.

  In order to simplify the description, it is assumed that a storage area for storing the number of times the fuel tank 15 is filled is secured in the three control devices of the vehicle controller 19, the inverter 18, and the power management device 17. In addition, the selection condition will be described as a condition that is selected by majority from the number of fillings stored in the vehicle controller 19, the inverter 18, and the power management device 17.

  FIG. 7 is a flowchart of the filling number succession process when the vehicle is started in the filling number storage succession system according to the embodiment of the present invention.

  As shown in FIG. 7, when the main switch 71 is turned on, the filling number storage succession system 69 of the fuel cell vehicle 1 according to the present embodiment includes three control devices (for example, the vehicle controller 19, the inverter 18, and The power management device 17) compares the number of fillings of the fuel tank 15 stored therein, and rewrites the storage area with the number of fillings satisfying the selection condition from the three filling times.

  Specifically, each control device (the vehicle controller 19, the inverter 18, and the power management device 17) reads the number of fillings from each storage area when the main switch 71 is turned on (Yes in step S21) ( Step S22). Here, the number of fillings read from the storage area by the control device is called a filling number Ns, and the number of fillings read from the storage area by another control device is called a filling number No.

  Each control device transmits the read filling frequency Ns in both directions (step S23). Each control device receives the number of fillings No from another control device (step S24).

  Subsequently, the filling number Nm occupying a majority (majority) is extracted from the respective control devices, the filling number Ns stored by itself, and the filling number No received from the other control devices by majority (step S25).

  Each control device compares the number of fillings Ns stored by itself with the number of fillings Nm (majority) extracted by the majority decision (step S26). Then, each control device extracts the filling number stored by itself by majority decision if the filling number Ns stored by itself is different from the filling number Nm extracted by majority decision (No in step S26). The number of times of filling Nm is changed (step S27), and the process is terminated. If the number of filling times Ns stored in the control device is the same as the number of filling times Nm extracted by the majority decision (Yes in step S26), each control device does not change the number of filling times Ns stored in itself. Then, the process ends by bypassing step S27.

  The fuel cell vehicle 1 according to the present embodiment includes a plurality of control devices such as a vehicle controller 19 and an inverter 18, for example, and compares predetermined times Na and Nb of the fuel tank 15 when a predetermined start condition is satisfied. In order to rewrite the storage area with the number of times of filling satisfying the selection condition among the plurality of times of filling Na and Nb, the number of times of filling the fuel tank 15 is shared and stored by a plurality of control devices. As a result, the fuel cell vehicle 1 can reliably take over the number of fillings of the fuel tank 15 and thus continue to reliably count the number of fillings of the fuel tank 15 regardless of which control device including the vehicle controller 19 is replaced. it can. This ensures the life management of the fuel tank 15 and increases the reliability of the fuel cell vehicle 1.

  In addition, the fuel cell vehicle 1 according to the present embodiment matches the number of fillings with the largest value among the number of fillings stored in the plurality of control devices or a value occupying the majority, so the number of fillings stored in the plurality of control devices. Can be matched to the true value very accurately.

  Further, in the fuel cell vehicle 1 according to the present embodiment, a plurality of control devices store data at the time of starting operation of the main switch 71 and at least one time when the fuel filling port lid 62 is opened. In order to make the number of fillings coincide, a plurality of control devices memorize in conjunction with the operations that can be performed by the occupant after the vehicle is completed or after the vehicle is serviced until the fuel is filled, that is, the internal pressure of the fuel tank 15 increases. The number of fillings can be reliably matched.

  The fuel cell vehicle 1 according to the present embodiment generates power by reacting the hydrogen gas stored in the fuel tank 15 and oxygen in the air with the fuel cell 2 and drives the motor 3 with this electric power to travel. The present invention also applies to a vehicle that needs to control the number of times the fuel tank 15 is filled, for example, a vehicle including an internal combustion engine that converts hydrogen gas stored in the fuel tank 15 and oxygen in the air into kinetic energy. Applicable.

  Therefore, according to the vehicle according to the present invention, the number of times of filling the fuel tank 15 for storing the fuel gas can be reliably counted even when the control device is replaced due to failure or the like.
