In this embodiment, the memory of the control circuit 2 stores data on the mileage of the vehicle (total mileage) as travel-related records accumulated as the vehicle travels, and data on the toll road. Cumulative data of the fees paid, as well as places where the vehicle has been visited (in this case, prefectures)
Visit history data is stored. Therefore, the memory of the control circuit 2 functions as storage means.

In this case, as will be described later, the control circuit 2 updates (accumulates) the data of the entire traveling distance at an appropriate timing (for example, every 1 km) while the vehicle is traveling. It has become. Further, each time the vehicle passes through the tollgate on the toll road, the toll paid is added (accumulated) to the data of the toll road cumulative toll.
Further, each time a vehicle visits a new prefecture, the visit history data (and the domination rate data) is updated. At this time, the control circuit 2 includes a large number of pictures for displaying the travel-related records (total travel distance data, toll road accumulated toll data, and visit history data) used on the drive notebook screen or the navigation license screen. Data is also stored in advance.

As will be described later in the description of the operation,
The control circuit 2 displays, on the drive notebook screen of the display device 6, the total travel distance data and the toll road accumulated toll data, which are travel-related records, on the screen including a pictorial display that changes according to the accumulation. ing. Further, on the navigation license screen, the visit history data, which is a driving-related record, is displayed on the screen including a pictorial display that changes according to the accumulation. Therefore, the control circuit 2 functions as a display control unit.

Specifically, as shown in FIGS. 1 and 3, respectively, on the drive notebook screen and the navigation license screen,
Three display areas for performing picture display, that is, a map display section A at the lower right of the screen, a character display section B at the upper left,
A home icon display section C is provided substantially in the center. Further, in the lower left portion of the screen, the total mileage and the toll road cumulative toll (the archipelago dominance rate on the navigation license screen) are displayed numerically. Note that a map switching key is set on the touch panel at the lower center of the screen, and a function switching key is set on the touch panel at the upper side of the screen.

At this time, in the present embodiment, on the drive notebook screen, the map display section A displays a picture such that the user travels around the world virtually according to the total mileage of the vehicle starting from home. The total distance traveled is converted to the actual distance and plotted along with the route on the world map. For example, the total mileage is 200000
km, and the distance to Egypt is 200000 km, a plot is made in Egypt as a virtual current arrival point, as shown in FIG. In the lower part of the map display section A, the country name and the city name are also displayed.

Next, the operation of the above configuration will be described with reference to FIG. The flowchart of FIG. 5 shows a processing procedure executed by the control circuit 2 for updating the travel-related records (total travel distance data and toll road accumulated toll data) in the memory and displaying the drive notebook screen.

That is, for example, when the vehicle is turned on (ACC
ON), the power of the navigation device 1 is automatically turned on, and navigation processing such as detection of the current position of the vehicle is executed. In parallel with this, for example, every time the vehicle travels 1 km, The running distance is added (accumulated) to the total running distance (step S1), and the total running distance data is stored (updated) in the memory (step S2). At the same time, the display data displayed on the map display section A and the character display section B is updated according to the total travel distance data (step S3).

On the other hand, during traveling, it is always monitored whether or not the vehicle has passed a tollgate on a toll road such as a highway (step S4). When the vehicle has passed the tollgate (Yes), the toll paid at that time is accumulated. It is added to the toll (step S5), and the toll road cumulative toll data is stored (updated) in the memory (step S6). At this time, it is determined whether the accumulated charge has exceeded a certain value as shown in FIG. 2 (step S7). If it has exceeded (Yes), it should be displayed on the home icon display section C according to the amount. The display data is updated (step S8). still,
When the vehicle does not pass through the tollgate on the toll road (No in step S4), and when the accumulated toll does not exceed a certain value (No in step S7), the process proceeds to step S9.

Here, when the power of the navigation apparatus 1 is turned on, a map around the current location of the vehicle is displayed on the screen of the display apparatus 6 together with a current location mark or the like in a normal state (step S11). When the user wants to display the drive notebook screen on the screen of the display device 6, the user operates the operation switch group 5 (or the remote controller 7) to temporarily set the menu screen, and then selects and designates the drive notebook screen ( (Yes in step S9). Then
The control circuit 2 causes the display device 6 to display a drive notebook screen (step S10).

As described above, on the drive notebook screen, numerical values of all the mileage data stored in the memory are displayed as shown in an example in FIG. 1 (212326 k in the figure).
m) At the same time, based on the display data according to the distance, a plot is made in Egypt's Cairo on the world map of the map display unit A as a virtual arrival point of a trip around the world. Is displayed on the character display section B. Also, the numerical value of the toll road accumulated toll data stored in the memory is displayed (82100 yen in the figure), and at the same time, a home icon (see FIG. 2) corresponding to the amount is displayed on the home icon display section C. is there.

In this case, the total mileage is represented by not only the numerical display but also the pictorial display on the map display part A and the character display part B which changes according to the distance. The information is displayed in a manner that is easy for the user to understand (easy to feel), and has amusement (amusement). In addition, the toll road cumulative toll is expressed not only in numerical display but also in the home icon display section C including a pictorial display of a home icon.
Since the home icon is upgraded as the amount of money increases, the accumulation of the toll paid by the user on the toll road is displayed in an easily understandable and entertaining manner.

Although illustration is omitted in FIG. 5,
The control circuit 2 updates the visit history data in the memory every time the vehicle visits a new prefecture.
Then, when the user operates the map switching key on the drive notebook screen, the screen of the display device 6 is switched to the navigation license screen. In this navigation license screen, as shown in FIG. 3, a map of Japan is displayed on the map display section A, and the prefectures that have been visited according to the visit history data are different from the others. Filled with another color.

With this, the accumulation of the prefectures where the vehicle has visited can be displayed in an easy-to-understand manner by the pictorial display and with amusement, and by increasing the accumulation, the accumulation on the map can be increased. Since the values of the filled prefectures and archipelago dominance are increasing, it is possible to give the user a sense of accomplishment of the drive.

As described above, according to the present embodiment, the driving-related records (total mileage data, toll road accumulated toll data, and visit history data) are displayed on the screen of the display device 6 (drive notebook screen or navigation license screen). Since the display is configured to include the display, it is possible to display the accumulated driving-related records in an easy-to-understand manner and add amusement, unlike the conventional method that displays the total mileage and toll road cumulative toll only with numerical values. It is possible to obtain an excellent effect that it can be performed.

In the above embodiment, three types of data, that is, total travel distance data, toll road accumulated toll data, and visit history data, are displayed as travel-related records.
Any one or two types of data may be displayed, and other travel-related records, such as a cumulative record of a facility that has been performed or a cumulative record of a road that has been driven, may be displayed as a picture. The display may be configured to include the display. It goes without saying that various modifications can be made to the form and specific contents of the picture display.

In the above-described embodiment, the present invention is applied to a car navigation system. However, in recent years, a vehicle control, a status display of a car air conditioner, a car navigation system, an audio system, a TV, a video system, etc. The present invention may be applied to a display unit called a multi-vision that also serves as a display. In addition, the present invention can be appropriately modified and implemented without departing from the gist, for example, the hardware configuration of the car navigation device 1 can be variously modified.
