In this embodiment, four types of fuel consumption levels and colors are used as shown in the figure, but more levels and colors may be used.

Next, the operation of the on-vehicle navigation device according to the present embodiment will be described with reference to the flowcharts shown in FIG. Programs for realizing the functions shown in these flowcharts are stored in the recording medium 28 in the form of program codes readable by the CPU 4. That is, when a predetermined mode is set by operating the key block 21, the CPU 4 operates according to the program code stored in the recording medium 28, that is, according to the flowchart shown in FIG. Then, a destination setting process is performed (step SA1), and a CD that can display a route to the destination input in the key block 21 is displayed.
The map 12 is read from the block 5 and the map based on the map data and the route to the destination are displayed on the monitor 12. By the processing in step SA1, as shown in FIG. 5, the route R from the current location (departure location) RS to the destination RE is displayed on the monitor 12.

Subsequently, a running section mode setting process (step SA2), which will be described later, and a running section average fuel efficiency calculation process based on the fuel flow rate data (step SA3) are performed.
The section after traveling is colored according to the average fuel value and displayed on the screen (step SA4). Further, after each average value is stored (step SA5), the stored average value is displayed (step SA6), and subsequently, a refueling response process (step SA7), which will be described later, and an oil change response process (step SA8). ), A tire replacement correspondence process (step SA9), and a vehicle inspection correspondence process (step SA10).

The running section mode setting process (step S
A2) is to display the average fuel efficiency on the route R by color.
Whether the display by color is performed for each set distance, for each road type such as an expressway, a national road, a prefectural road, or the like, or a traffic congestion condition such as large congestion, medium congestion, small congestion, and non-congestion obtained from VICS information This is a process for setting whether to perform each process or to use them together, and is performed according to the flowchart shown in FIG.

That is, it is determined whether any one of the setting modes for each distance, each road, and each congestion state is selected by the user's operation on the key block 21 (step SB).
1). As a result of this determination, if each distance is selected and input, it is fetched (step SB2). Subsequently, the distance unit (for example, every 5 km) set and input by the user is selected and stored in the average fuel efficiency memory 7a for each set distance in the RAM 7. It is stored (step SB3).

If a road type is selected and input, it is fetched (step SB4), and the type of road continuously set by the user (for example, expressway, national road, prefectural road).
Is selected and stored in the road average fuel efficiency memory 7b of the RAM 7 (step SB5). Further, if the congestion status is selected and input, it is taken in (step SB6), and the congestion status type (for example, large congestion, medium congestion, small congestion, non-congestion) continuously obtained from the VICS information is selected and RA is selected.
It is stored in the average fuel efficiency memory 7c according to the congestion status of M7 (step SB7).

In step SB8 following steps SB3, SB5 and SB7, it is determined whether or not a mode in which the three modes (distance, road, and congestion state) are used together is selected. When the three modes are not used together, the process proceeds to step S10. When the three modes are used together, it is determined whether the selection and setting of all the setting modes are completed (step SB9), and all the three modes are selected. If the setting has not been completed, the processing from step SB1 is repeated.

In the case where the three modes are not used together, and any of the settings for each distance, each road, and each congestion state has been completed, or in the case where the three modes are used together, If all the settings for each road and each congestion state have been completed, after confirming the setting mode of each traveling section and calculating the distance of the setting section (step SB1)
0), the section setting completion processing is performed (step SB1)
1), the processing according to the flow shown in FIG. 6 ends.

The average fuel efficiency calculation process for the traveling section based on the fuel flow rate data (step SA3) is executed according to the flowchart shown in FIG.
It is determined whether or not the vehicle has traveled the set distance (5 km) input with the setting of the distance-by-distance mode based on the current position information from (step SC1). Then, when the vehicle has traveled the set distance, the average fuel efficiency at the traveled set distance is calculated and stored (step SC2). That is, the average fuel efficiency is calculated by dividing the fuel flow rate measured by the fuel flow rate sensor 30 by the set distance (5 km) from the time when the vehicle has traveled the previously set distance to the time when the vehicle has traveled the current set distance.

If the vehicle is not traveling the set distance (including the case where the per-distance mode is not set), it is determined whether or not the type of the traveling road has changed (step SC3). If there is, the average fuel efficiency of the road type before the change is calculated and stored (step SC
4). That is, for example, when there is a change from the expressway to the national road, the average fuel efficiency is calculated by dividing the fuel flow rate measured by the fuel flow rate sensor 30 by the distance of the expressway by the time before the change. .

When there is no change in the type of the road on which the vehicle is traveling (including the case where the road mode is not set).
In step S5, it is determined whether or not the congestion degree of the road on which the vehicle is traveling has changed (step SC5). If the congestion degree has changed, the average fuel efficiency at the congestion degree before the change is calculated (step S5).
C6). That is, the information on the degree of congestion of the traveling route R is sequentially obtained from the VICS information, and based on this information, the traveling road is classified into one of large congestion, medium congestion, small congestion, and non-congestion. Can be determined. If the state changes from any one of the states to another state, for example, from heavy traffic to medium traffic, the fuel flow rate measured by the fuel flow rate sensor 30 is changed by the time before the change. The average fuel efficiency is calculated by dividing by the distance traveled in the state.

In step SC7 following any of steps SC2, SC4, and SC6, the average fuel efficiency over the total distance is calculated. That is, the total average fuel consumption memory 7j stores the average fuel consumption at the total traveling distance, which is the distance traveled since the navigation device was mounted on the vehicle. Therefore, any of steps SC2 and SC2
4. The average value is calculated by adding the average mileage calculated in SC6, and the contents stored in the total average mileage memory 7j are updated to the calculated average value in step SA5. Note that the average value of the total traveling distance for each road type and congestion degree in the total average fuel consumption memory 7j may be stored, and these may be calculated and updated.

After the processing according to the flow shown in FIG. 7 is executed in step SA3 in FIG. 4, in the subsequent step SA4, the section after traveling is color-coded according to the average fuel consumption value as described above. Display on the screen. Therefore,
For example, when the distance-by-distance mode is set, each time the vehicle travels the set distance, the route R becomes black, as shown in FIG.
The color is displayed in one of red, yellow, and blue. Of course, if the adjacent set distances are the same average fuel efficiency, the route R between them is displayed in the same color as shown in FIG.

When the road-by-road mode is selected, the display is colored in a color indicating the average fuel efficiency corresponding to each of the expressways, national roads, and prefectural roads. Is displayed in a color indicating the average fuel efficiency in each of the areas of large congestion, medium congestion, small congestion, and non-congestion on the route R. Further, when the three modes are selected, the display states in the distance-by-distance mode, the road-by-road mode, and the congestion status mode are switched and displayed at predetermined time intervals, for example. Therefore, by visually recognizing the color display on the route R, the driver can drive while recognizing the average fuel efficiency that changes over time.

Then, step S following step SA3
At A4, the average fuel efficiency calculated and displayed as described above is stored. That is, as described above, the total average fuel consumption memory 7j is updated, and when the per-distance mode is set, the average fuel consumption calculated for each run of the set distance is set together with the position on the route R. The average fuel efficiency memory for each distance 7a is stored. If the road-specific mode is set, the average fuel efficiency calculated for each type of road on which the vehicle travels is stored in the road-specific average fuel efficiency memory 7b together with the road type and its position.

Further, when the mode for each congestion condition is set, the average fuel efficiency for each congestion condition is stored in the average fuel consumption memory for each congestion condition 7c together with the congestion degree (high traffic congestion) and the position of the congestion. Remember. Of course, when three modes are used together, the average fuel consumption memory 7 for each set distance is used.
a, the above-mentioned data is stored in the average fuel efficiency memory 7b for each road and the average fuel efficiency memory 7c for each congestion situation. Therefore, at the time when the vehicle has traveled all the way along the route R,
The average fuel efficiency at a plurality of locations is stored in the memories 7a to 7c in accordance with the selected mode or the combination of the three modes.

Step SA5 following step SA5
In step 6, the average fuel efficiency of each item is numerically displayed, thereby displaying the latest average fuel efficiency (fuel efficiency for each latest set distance) in a predetermined area other than the map on the monitor 12 as shown in FIG. To fuel efficiency during non-congestion are displayed. Therefore, by visually recognizing the numerical display, the driver can grasp the fuel efficiency of the own vehicle in more detail for each item.

Further, the refueling response processing in step SA7 following step SA6 in FIG. 4 is performed according to the flowchart shown in FIG. That is, the remaining fuel in the fuel tank detected by the remaining fuel sensor 31 is read (step SD1), and then the average fuel consumption stored in the average fuel consumption memory 7a for each set distance is read (step SD2).
Further, based on the read fuel remaining amount and the average fuel efficiency, the remaining fuel amount is divided by the average fuel efficiency to calculate a distance on the route R to a point where the fuel tank becomes empty (step SD3). The predicted point is predicted by searching the map data (step SD4). Subsequently, a plurality of gas stations that are closer to and closer to the predicted point than the point are identified by the map C along with the map data.
A search is made from the gas station information stored in the D-ROM 6 (step SD5).

Next, the user request information input by the driver through the operation of the key block 21 is fetched (step S).
D6). Here, the user request information is the maker and price of gasoline that the user wants to enter, and the maximum distance (detour distance MAX) that the user may detour when detouring from the route R to the selected gas station. And so on.

When the user request information is fetched, the gas station closest to the user's request, taking into account the user's request information, from the plurality of gas stations predicted (retrieved) in step SD5 described above. Is extracted. At this time, since the gas station information includes the business day and business hours of each gas station as described above, the optimal gas station is also considered in consideration of the current date and time and the estimated arrival time at the gas station. Perform the extraction.

Thereafter, the monitor 12 displays the extracted optimal gas station. The display of the optimum gas station is performed by displaying a predetermined mark at a corresponding position on the map displayed on the monitor 12. Therefore, by visually recognizing this mark, the driver can fill in gasoline of a desired make and price at an appropriate time before running out of fuel, and
It is possible to drive in a stable mental state without worrying about running out of gas. The display of the optimal gas station is not based on the mark display on the map, but on the character display on the monitor 12 or the speaker 20.
The notification may be made by a voice from the user.

Further, the oil exchange correspondence processing in step SA8 following step SA7 in FIG. 4 is performed according to the flowchart shown in FIG. That is, the previous oil change date stored in the oil change date memory 7d is read (step SE1). Next, the total mileage memory 7g
Is divided by the period stored in the period memory 7i to calculate the average traveling distance per day (step SE2).
Based on the average traveling distance per day, a 5,000 km traveling completion date is predicted (calculated) from the previous oil change date (step SE3). That is, the last oil change date is stored in the oil change date memory,
Since the average traveling distance per day has been calculated by the processing in E2, the traveling date of 5,000 km from the previous oil change date can be calculated based on these.

Then, the calculated predicted date, which is the date, is displayed on a predetermined portion of the monitor 12 as an oil replacement encouragement date (step SE4). Therefore, by visually recognizing this display, the driver can know in advance the oil change time for every 5,000 km traveling, which is generally the engine oil change time. Therefore, the oil change can be performed systematically, and the adverse effect on the engine and the fuel efficiency due to the delay of the oil change due to the enforcement of the oil change can be prevented.

Further, the tire replacement correspondence processing in step SA9 following step SA8 in FIG. 4 is performed according to the flowchart shown in FIG. That is, the previous tire replacement date stored in the tire replacement date memory 7e is read (step SF1). Next, as described above, the average mileage per day is calculated by dividing the total mileage stored in the total mileage memory 7g by the period stored in the period memory 7i (step SF2). Based on the calculated average traveling distance per day, a 30,000 km travel completion date is predicted (calculated) from the previous tire replacement date (step SF3). That is, the last tire replacement date is stored in the tire replacement date memory, and the average mileage per day is calculated by the processing in step SF2. The date of traveling 30,000 km from the day can be calculated.

The calculated predicted date, which is the date, is displayed on a predetermined portion of the monitor 12 as a tire replacement recommendation date (step SF5). Therefore, by visually recognizing this display, the driver can know in advance the tire replacement time every 30,000 km traveling, which is generally the tire replacement time. Therefore, tire replacement can be performed systematically, and a decrease in running stability due to tire replacement being delayed due to tire replacement being enforced can be prevented.

Further, the vehicle inspection corresponding process in step SA10 following step SA9 in FIG. 4 is performed according to the flowchart shown in FIG. That is, the vehicle inspection deadline date stored in the vehicle inspection memory 7f is read (step SG).
1) The current date stored in the current date memory 7i is read (step SG2). Subsequently, the remaining period of the vehicle inspection is calculated by “the vehicle inspection deadline date—the current date = the remaining period” (step SG3), and the vehicle inspection deadline obtained by adding the calculated remaining period to the current date is obtained. The date and the remaining period are displayed on a predetermined portion of the monitor 12 (step SG4). Therefore, by visually recognizing this display, the driver can know in advance the date of the vehicle inspection deadline of the vehicle owned by the driver and the remaining period of the vehicle inspection. Therefore, the vehicle can be systematically sent out for vehicle inspection, and the violation of laws and regulations that drives the vehicle after the vehicle inspection deadline is prevented.

FIG. 13 is a flowchart showing the contents of the traveling section mode setting processing (step SA2) according to another embodiment of the present invention. In this flowchart, steps SH1 to SH10 and step S
The processing in H14 is performed in steps SB1 to SB in FIG.
This is the same as 10 and step SB11. Then, in step SH12 following step SH11, the fuel consumption to the destination is predicted based on the past data, and in step SH13, the fuel consumption prediction is displayed.

That is, as described above with reference to FIG. 2, the RAM 7 has an average fuel economy memory 7a for each set distance, an average fuel economy memory 7b for each road, and an average fuel economy memory 7 for each congestion situation.
c, a total average fuel consumption memory 7j is provided, and these memories 7a to 7c, 7j store past data. Therefore, it is possible to calculate the fuel consumption to the destination based on the average value of any or all of the past data and the distance to the destination obtained from the map data. Therefore, the amount of fuel used up to the destination is calculated and displayed, whereby the user can know in advance the amount of fuel required to the destination, and understand the cost required for traveling to the destination and the number of times of refueling. can do.

In this embodiment, the GPS
