After returning from the fuel information display process subroutine, in step S102, a fuel supply prompting process subroutine is executed. When the process returns from the refueling prompting subroutine, the remaining amount warning processing subroutine is executed in step S103. When returning from the remaining amount warning processing subroutine,
Next, in step S104, it is determined whether or not the gas station presentation flag is 1. When the result of determination in step S104 is YES, the process proceeds to step S105, and when the result of determination in step S104 is NO, the process proceeds to step S101.

  In step S105, a subroutine for refueling information display processing is executed. When the routine returns from the refueling information display processing subroutine, it is next determined in step S106 whether or not the vehicle engine has been stopped. When the determination result is NO, the process returns to step S101. If the determination result is YES, the process proceeds to step S107, and the fuel supply assist process is terminated.

  In the following description, the term “fuel supply” is used as a subordinate concept of “fuel supply” in the claims, and for example, drives electric and electronic components such as a motor disposed in a vehicle. If the vehicle is capable of supplying electricity or hydrogen used to make electricity, the electricity and hydrogen are fuel, and "fuel supply" means that these fuels are necessary for running the vehicle. It is a concept that is intended to be supplied as energy.

  Next, the fuel supply door closing forgetting prevention process, which is the second main process of the assist process of the fuel supply assist device, will be described. After the end of the second main process, or after a lapse of a predetermined time after the fuel supply, a process is performed so as to shift from the second main process to the first main process.

  Details of the subroutine for preventing forgetting to close the fuel filler door will be described. FIG. 2 is a view illustrating a flowchart of the forgetting to close the fuel filler door of the fuel supply assist device according to the embodiment of the present invention. This subroutine notifies the driver when the fuel filler door is open, and executes a process for making the vehicle impossible to run when the fuel filler door is open.

  In FIG. 5, when the subroutine for forgetting to close the fuel filler door is started in step S200, the process proceeds to step S201, where it is determined whether or not the fuel flag = 1. When the determination result of step S201 is YES, the process proceeds to step S202. When the determination result of step S201 is NO, the process proceeds to step S208, and the process ends.

  In step S202, the select lever is locked by the select lever locking mechanism 320. Thus, in a state where the fuel filler door 401 is open, the select lever is locked, so that it is not possible to change to a travel mode such as a drive range, and the vehicle cannot travel.

  In step S <b> 203, the state of the filler port door 401 is acquired from the filler port position detection unit 420.

  In the next step S204, it is determined whether or not the fuel filler door 401 is in an open state. When the determination result of step S204 is NO, the process proceeds to step S206, and when it is YES, the process proceeds to step S205.

  In step S205, a warning is displayed on the display 610 indicating that the fuel filler door 401 is open. An example of such a warning display is shown in FIG. In FIG. 11, the display of “the fuel filler door is open” is pulled out from the rear left side of the imaged vehicle, and such a display corresponds to the state of the actual fuel filler door 401. It has become.

  In step S206, the select lever lock mechanism 320 releases the lock of the select lever. In step S207, the refueling flag is set to zero.

  According to the processing described above, when the fuel supply port door 401 is open, information indicating that the fuel supply port door 401 is open is displayed on the display 610. Therefore, when the fuel is supplied, the fuel supply port door is displayed. An appropriate assist operation is performed, for example, the state of 401 can be appropriately notified to the driver.

In addition, when the fuel supply port door 401 is opened, the operation of the select lever is locked by the select lever locking mechanism 320, so that after the fuel is supplied, the vehicle is driven with the fuel supply port door 401 opened. For example, an appropriate assist operation is performed.

  Next, details of the above subroutines will be described. FIG. 6 is a flowchart of the fuel information display process (subroutine) of the fuel supply assist device according to the embodiment of the present invention. This subroutine makes it possible to notify the driver of basic information related to the fuel, whereby the driver can supply fuel appropriately.

  In FIG. 6, when the fuel information display processing subroutine is started in step S300, the process proceeds to step S301, and fuel remaining amount data is acquired from the fuel remaining amount detection unit 220.

  In the next step S302, average fuel consumption data is calculated from the travel history database 510.

  In the next step S303, as shown in FIG. 3B, the remaining fuel amount data and the calculated average fuel consumption data are displayed on the display 610.

  In the next step S304, the process returns to the main routine.

  Next, details of a subroutine for the fuel supply prompting process will be described. FIG. 7 is a view showing a flowchart of a fuel supply prompting process (subroutine) of the fuel supply assist device according to the embodiment of the present invention. This subroutine calculates the amount of fuel required according to the destination set by the navigation system unit 800, and performs processing to prompt the driver to refuel when there is a shortage. According to this, the driver can appropriately refuel. In the navigation system unit 800, a technique well known in the art can be used as a technique used when setting a registered destination such as a destination or a home.

  In FIG. 7, when a subroutine for refueling prompting is started in step S400, the process proceeds to step S401, where it is determined whether or not the destination is already set in the navigation system unit 800.

  When the determination result in step S401 is YES, the process proceeds to step S402, and in step S402, the route from the current position of the vehicle to the destination is set.

  When the determination result in step S401 is NO, the process proceeds to step S406, and in step S406, a route from the current position of the vehicle to a registered place (such as home) is set as a route.

  In the route setting as described above, information stored in the database 820 of the navigation system unit 800 is used.

  In step S403, the required fuel amount data is calculated from the set route. When such a calculation is performed, it is most simply obtained by the product of the set route distance and the average fuel consumption. Further, more complicatedly, it is possible to store the terrain gradient information and legal speed information in the database 820 and calculate the fuel amount data by taking the gradient information and legal speed information into consideration. .

In step S404, fuel remaining amount data is acquired from the fuel remaining amount detecting unit 220. Then, in the next step S405, it is determined whether (remaining fuel amount)> (required fuel amount) is satisfied. When the determination result of step S405 is YES, the process proceeds to step S409 and returns to the main routine.

  When the determination result in step S405 is NO, the process proceeds to step S407, and in step S407, a warning that prompts refueling is given to the display 610. At this time, the driver can also be notified of the refueling prompt by voice using the speaker 630.

  In the next step S408, a substation for gas station presentation processing is executed. Although the substation of this filling station presentation process will be described later, it is a process of guiding the filling station (in a broader sense, the fuel supply station) using the navigation system unit 800 to the driver. Then, the process proceeds to step S409 and returns to the main routine.

  Next, details of a subroutine for remaining amount warning processing will be described. FIG. 8 is a flowchart of the remaining amount warning process (subroutine) of the fuel supply assist device according to the embodiment of the present invention. In this subroutine, when the remaining amount of fuel is equal to or less than a predetermined amount, a process for notifying the driver is performed. According to such a process, the driver can take an appropriate fuel supply action. .

  In FIG. 8, when the subroutine for the remaining amount warning process is started in step S <b> 500, the process proceeds to step S <b> 501 and the remaining amount data of the fuel in the fuel tank is acquired from the remaining fuel amount detection unit 220.

  In subsequent step S502, it is determined whether or not the remaining amount data is equal to or less than a predetermined amount. If the determination result in step S502 is NO, there is no need for warning, so the process proceeds to step S505 and returns to the main routine.

  When the determination result in step S502 is YES, the process proceeds to step S503, and a fuel warning lamp as shown in FIG. Next, in step S504, a substation for a gas station presentation process is executed. Although the substation of this filling station presentation process will be described later, it is a process of guiding the filling station (in a broader sense, the fuel supply station) using the navigation system unit 800 to the driver. Proceeding to step S505, the process returns to the main routine.

  Note that the warning display of the remaining amount of fuel in step S503 may be designed as shown in FIG. FIG. 12 is a view showing a display example of a fuel remaining amount warning display in the fuel supply assist device according to the embodiment of the present invention. According to what is shown in FIG. 12, it is possible to refer to information such as the distance to the destination, the cruising distance, and the normal fuel consumption.

  Next, the details of the subroutine for the gas station presentation process will be described. FIG. 9 is a flowchart of a filling station presentation process (subroutine) of the fuel supply assist device according to the embodiment of the present invention.

  When the filling station presentation process is started in step S600, the process proceeds to step S601, where the set route is read. In step S602, filling stations (fuel supply stations) in and near the set route are extracted from the database 820 of the navigation system unit 800 and presented on the display 610 as shown in FIG. 3A. To do. In step S603, the gas station presentation flag is set to 1. In step S604, the process returns and returns to the original routine. In FIG. 3A, the mark “GS1” indicates a fueling station (fuel supply station).

  In addition, the display as shown, for example in FIG. 13 can also be used for the display of the filling station (fuel supply station) in step S602. FIG. 13 is a diagram showing a display example of a filling station presentation process in the fuel supply assist device according to the embodiment of the present invention. According to such a display, it is possible to notify the driver of the distance to the gas station, the price information of gasoline, and the like.

  Next, the details of the subroutine of the refueling information display process will be described. FIG. 10 is a flowchart of a fuel supply information display process (subroutine) of the fuel supply assist device according to the embodiment of the present invention. In this subroutine, when it is determined that the vehicle has entered a fuel supply station such as a gas station, the driver executes various assists for refueling.

  In FIG. 10, when a subroutine for refueling information display processing is started in step S700, the process proceeds to step S701, where the navigation system unit 800 reads the current position of the vehicle.

  In subsequent step S702, it is determined whether or not (current position of vehicle) = (position of gas station) by referring to database 820. When the fuel supplied to the vehicle is not necessarily gasoline, the “fuel station” is assumed to be a “fuel supply station”. A fuel supply station is a place where, for example, electricity for driving electric and electronic parts such as a motor arranged in a vehicle, hydrogen used for making electricity, etc. can be supplied, such as running of a vehicle It is a predetermined place where energy necessary for the can be supplied.

  When the determination result in step S702 is NO, the process proceeds to step S701. If the determination result in step S702 is YES, the process proceeds to step S703.

  In step S703, information on the oil type is displayed on the display 610. Here, the oil type means a type such as “regular gasoline” or “high-octane gasoline”. The screen display of “Oil type information This car is regular” shown in FIG. 3C on the display 610 is the display in step S703.

  According to such a process, information on the type of fuel to be supplied to the vehicle is displayed on the display 610. Therefore, even for a driver who is not interested in the type of fuel, appropriate information at the time of fuel supply can be obtained. An assist operation can be performed.

  For example, when the vehicle is operated with electric energy, “power supply standard display” may be performed instead of such “oil type information display”.

  In step S704, information related to the position of the fuel filler opening in the vehicle is displayed on display 610. In FIG. 3C, the display of “the position of the fuel filler port is here” is pulled out from the rear left side of the image displayed vehicle, and this pull-out location corresponds to the position of the fuel filler port in the actual vehicle. It is like that.

  According to such a process, since the information related to the position of the fuel supply port in the vehicle is displayed on the display 610, even a driver who is not interested in the position of the fuel supply port can be provided at the time of fuel supply. An appropriate assist operation can be performed.

In the next step S705, it is determined whether or not the vehicle has stopped before the fuel filler (or under the pump in the case of a suspension type) by the fuel filler detector 910. When the determination result at step S705 is NO, the process proceeds to step S703, and when the determination at step S705 is YES, the process proceeds to step S706.

  In step S706, a button for opening the fuel filler door is displayed. This button display corresponds to the display section of “Pressing this button opens the filler door” in FIG. Here, the fuel supply port door 401 is configured to open when the driver touches the touch panel 620 on the display button. That is, when the driver touches the display unit “open the fuel filler door by touch”, the fuel supply port door opening / closing control unit 410 is caused to execute control to open the fuel supply port door 401.

  According to such processing, a button for opening the fuel supply port door 401 automatically appears on the display when the fuel station (fuel supply station) is reached, and the driver performs a final safety check or the like. By touching this button, the fuel supply port door 401 can be opened.

  In step S707, it is determined whether or not the button for opening the fuel filler door has been pressed. When the determination result of step S707 is YES, the process proceeds to step S708, and when NO, the process proceeds to step S706. In step S708, the refueling flag = 1 is set, and in the next step S709, the process returns to the main routine.

  As described above, according to the fuel supply assist device of the present invention, when the fuel supply station is reached, the button for opening the fuel supply port door automatically appears on the display, and the driver performs a final safety check and the like.
