The car navigation device 5 is mainly composed of a navigation main body 10, a touch panel display 20, a GPS receiver 30, and a vehicle fuel measurement device 40.

  The navigation main body 10 includes a CPU 11, a position information acquisition unit 13, a time information unit 14, a memory 12, a map information storage unit 15, a route setting unit 16, and a guidance information generation unit 17.

  The fuel consumption history display device of this embodiment applied to the car navigation device 5 mainly includes a CPU 11, a touch panel display 20, a GPS receiver 30, a position information acquisition unit 13, a time information unit 14, a memory 12, and a map information storage. This is realized by the unit 15 and the vehicle fuel measuring device 40.

  The CPU 11 controls the entire car navigation device 5 and includes a ROM that stores a fuel consumption history display program (to be described later), a RAM that is used when the program is executed, in addition to a CPU that performs logical operations. The CPU 11 also has a function as display control means for controlling display on the touch panel display 20.

  A GPS (Global Positioning System) receiver 30 is attached to the vehicle and receives radio waves from a plurality of GPS satellites. The position information acquisition unit 13 measures the current position of the vehicle (GPS position information) based on the received signal sent from the GPS receiver 30.

  The time information unit 14 (time information acquisition means) is composed of an RTC (Real Time Clock) that measures the current date and time. The vehicle fuel measurement device 40 (fuel consumption information acquisition means) includes a fuel meter and a travel distance meter, and fuel consumption (travel distance / fuel consumption) as fuel consumption (fuel consumption) information every predetermined period (for example, 30 minutes). Measure.

  The memory 12 stores fuel consumption measured by the vehicle fuel measuring device 40 during traveling, a travel position (GPS position information) obtained from the position information acquisition unit 13, time information measured by the time information unit 14, and the like. .

  The map information storage unit 15 stores map information used for car navigation.

  The touch panel display 20 includes a liquid crystal display panel 20a as a display unit and a touch panel 20b as an input unit provided on the front surface thereof.

  The route setting unit 16 has a function of automatically determining a travel route from information such as a departure point and an arrival point input through the touch panel 20b, or setting a travel route from a trace traced on the touch panel 20b.

  The guidance information generation unit 17 generates information for guiding the progress of the vehicle along the travel route based on the GPS position information.

  The operation of the fuel consumption history display device having the above configuration will be described. FIG. 2 is a flowchart showing a fuel consumption history display operation procedure. This operation program is stored in the ROM in the CPU 11 and is executed by the CPU 11. The execution of this program is started, for example, when the user presses a predetermined operation button (not shown) on the touch panel 20b.

  First, the CPU 11 takes in fuel efficiency information from the vehicle fuel measuring device 40 (step S1). The CPU 11 stores the captured fuel efficiency information in the memory 12 together with time information obtained from the time information unit 14 in time series (for example, at intervals of 30 minutes) (step S2).

  Further, the CPU 11 records the GPS position information obtained from the position information acquisition unit 13 and stored in the memory 12 in the memory 12 (recording medium) in association with the fuel efficiency information (step S3).

  The CPU 11 displays the history of fuel consumption information stored in the memory 12 on the liquid crystal display panel 20a of the touch panel display 20 (step S4).

  FIG. 3 is a diagram showing a screen of the touch panel display 20 on which the history of fuel consumption information is displayed as a bar graph. In the history display of fuel consumption information, the fuel consumption measured every 30 minutes by the vehicle fuel measurement device 40 is displayed in time series as a bar graph. In addition, the display of the fuel consumption bar representing the fuel consumption of each section is color-coded for each rank of the fuel consumption. For example, when the fuel consumption is less than 10 km / l, the fuel consumption bar is displayed in red. When the fuel consumption is 10 km / l or more and less than 20 km / l, the fuel consumption bar is displayed in yellow. When the fuel consumption is 20 km / l or more and less than 30 km / l, the fuel consumption bar is displayed in light blue (dot display in the figure). When the fuel consumption is 30 km / l or more, the fuel consumption bar is displayed in green (indicated by hatching in the figure). Thereby, the change of the fuel consumption information along the traveling route is grasped.

  The CPU 11 determines whether or not any fuel consumption bar has been touched (pressed) by the user (step S5). When the fuel consumption bar is not touched, the CPU 11 proceeds to the process of step S7. The process in step S5 corresponds to an accepting unit.

  On the other hand, when any of the fuel consumption bars is touched, the CPU 11 displays the location where the fuel consumption corresponding to the touched fuel consumption bar is measured in a section on the car navigation map (step S6). The car navigation map may be switched to the original history display of fuel consumption information after being displayed for a predetermined time or by pressing a predetermined operation button on the touch panel 20b.

  Thereafter, the CPU 11 determines whether or not the display end is instructed by the user (step S7). When the display end is not instructed, the CPU 11 returns to the process of step S5. On the other hand, when the display end is instructed, the CPU 11 ends the present process.

  FIG. 4 is a diagram showing a car navigation map in which sections where fuel consumption is measured are drawn. On this map, a fuel consumption bar 61 indicated by a dotted circle g in FIG. 3 is pressed, and a section with the highest fuel consumption (39.6 km / l) is drawn as a rectangular travel section bar 101. The travel section bar 101 is displayed in the same color as the fuel consumption bar 61, and the travel section bar and the fuel consumption bar are associated with each other. That is, the travel section bar is displayed in a display mode in which the fuel consumption amount can be identified. In FIG. 4, the departure point S and the arrival point E are indicated by arrows as travel sections in which the fuel consumption information of FIG. 3 is measured.

  In this embodiment, the screen of the liquid crystal display panel 20a is switched between the fuel consumption history display screen (first screen) and the car navigation map display screen (second screen). It may be divided into. Alternatively, two displays may be provided instead of dividing the screen. For example, when the screen is divided into two, the fuel consumption history is displayed on one screen, and the map display of the car navigation is displayed on the other screen, whereby both displays are possible. As a result, the user can view the fuel efficiency information and the section corresponding to the fuel efficiency information at the same time, which improves usability.

  Further, when two or more fuel consumption bars are touched on the fuel consumption history display screen, two or more travel section bars corresponding to the respective fuel bars are displayed together on the car navigation map. You may do it.

  Thus, according to the fuel consumption history display device of the first embodiment, the location where the fuel consumption is measured can be grasped on the map from the screen of the fuel consumption history. Thereby, the history information of the fuel consumption for each traveled section is associated with the place where the fuel consumption is measured, and the fuel consumption information can be displayed in an easy-to-understand manner. Moreover, the place where the fuel consumption information selected by the user is measured can be easily known.

  Further, by comparing the fuel efficiency bar graph with the map, it is possible to know where the fuel efficiency is good or bad and to easily find a route (traveling route) with good fuel efficiency. In addition, the route that records the highest fuel efficiency is also known, which leads to energy-saving driving.

(Second Embodiment)
In the first embodiment, the fuel consumption history is displayed, and the section in which the fuel consumption is measured by pressing the fuel consumption bar is displayed on the car navigation map. The second embodiment shows a case where the fuel consumption of a specified section is displayed in a state where a car navigation map is displayed on the screen of the liquid crystal display panel. In addition, since the structure of the fuel consumption history display apparatus of 2nd Embodiment is the same as that of the said 1st Embodiment, the description is abbreviate | omitted.

  FIG. 5 is a flowchart showing a fuel consumption history display operation procedure in the second embodiment. This operation program is stored in the ROM in the CPU 11 and is executed by the CPU 11. The execution of this program is started, for example, when the user presses a predetermined operation button on the touch panel 20b. It is assumed that a navigation map is displayed on the screen of the liquid crystal display panel.

  First, the CPU 11 waits until the screen of the touch panel display 20 is pressed (step S21). FIG. 6 is a diagram illustrating how the touch panel 20b of the touch panel display 20 is pressed. The process in step S21 corresponds to an accepting unit.

  When the touch panel 20b of the touch panel display 20 is pressed by, for example, the finger 201, the CPU 11 detects a section on the travel route closest to the pressed position (touched position) and acquires the fuel consumption information from the memory 12 ( Step S22).

  CPU11 switches the screen of the liquid crystal display panel 20a, and displays a fuel consumption history (step S23). FIG. 7 is a diagram showing a screen of the touch panel display 20 on which the history of fuel consumption information is displayed as a bar graph. On the screen of the liquid crystal display panel 20a, the fuel consumption of the designated section is displayed as a fuel consumption bar 206.

  Similar to FIG. 3 described above, the fuel consumption in the designated section is displayed in the center, and the fuel consumption fuel bars 205 and 207 of the fuel consumption in the preceding and following sections on the travel route may be displayed simultaneously (in the figure, Broken line). In addition, when fuel consumption information for each hour is stored in the memory 12 in the designated section, for example, when fuel consumption information measured in the morning, daytime, and night is stored, these fuel consumption information is time-series. May be displayed. FIG. 8 is a diagram showing a screen of the touch panel display 20 on which a history of fuel consumption information in a specified section is displayed as a bar graph.

  After the process of step S23, the CPU 11 determines whether or not a predetermined operation button has been pressed to instruct the end of display of fuel consumption information (step S24). When the display end is not instructed, the CPU 11 returns to the process of step S21. On the other hand, when the display end is instructed, the CPU 11 ends the present process. Thereby, the navigation map is displayed on the screen of the touch panel display 20 as before. The history of the fuel consumption information may be automatically switched to the original navigation map display after being displayed for a predetermined time.

  Thus, according to the fuel consumption history display device in the second embodiment, the fuel consumption information for each section of the travel route can be examined from the screen on which the navigation map is displayed. Thereby, the history information of the fuel consumption for each traveled section is associated with the place where the fuel consumption is measured, and the fuel consumption information can be displayed in an easy-to-understand manner. Moreover, the fuel consumption information for every section of the route traveled on the map can be easily grasped.

  The present invention is not limited to the configuration of the above-described embodiment, and any configuration that can achieve the functions of the configuration of the present embodiment is applicable.

  For example, in the above embodiment, the travel section bar corresponding to the fuel consumption bar representing the fuel consumption of the designated section is displayed on the navigation map, but when the predetermined operation button is pressed, the section with good fuel consumption is displayed on the navigation map. Or a travel section bar for only a section with poor fuel consumption may be displayed. FIG. 9 is a diagram showing a navigation map in which a travel section bar is drawn only in a section with good fuel efficiency. In the navigation map of FIG. 9, only the traveling section bar 301 with good fuel efficiency is drawn. The user traces the travel route 350 on the navigation map displayed on the screen of the touch panel display 20 with a finger or a stylus pen, for example, selects a section with the best fuel efficiency as much as possible and selects the travel route (route). It becomes possible to set. In this way, the section with good fuel efficiency and the section with poor fuel efficiency are known, and the user can create a fuel saving travel route and register it in the car navigation. It is also possible to collect information from many users and create an energy saving route, or to create an energy saving route by time, day of the week, and purpose. It is also possible to determine whether the route is optimal compared with the driver's past data.
