Next, the operation of this embodiment will be described.

First, the operation of the ground side, that is, the general center 40 will be described in detail. In the present embodiment, general center 40 transmits information for billing processing to vehicle-mounted device 30 mounted on vehicle 32.

As shown in FIG. 4, in the general center 40,
In step 300, GPS satellites 20, 22, 24
In step 302, the GPS signal is received from the self, that is, the reference position of the comprehensive center 40 (reference latitude / longitude P).
o) is obtained and GPS correction information is generated. This GPS correction information is obtained from the GPS satellites 20, 22 and 24.
This is for correcting when the signal error is large, and since the general center 40 is fixedly installed, G
This is because even when the GPS signals from the PS satellites 20, 22, and 24 change, the in-vehicle device 30 side corrects this.

At the next step 304, the billing information is read from the memory 124 and the GPS correction information is transmitted together with the billing information at the next step 306. This transmission can be performed by FM broadcasting or a telephone line.

The billing information is defined by data indicating a billing target area Area composed of a plurality of predetermined areas and a billing amount corresponding thereto. Area to be charged Ar
As an example of ea, as shown in FIG. 5, it is divided into two areas, a rectangular area A and an area B adjacent to the area A. Each of these areas can be specified by data representing the latitude and longitude and its shape. The area of each area can be changed and the shape thereof can be changed as necessary.

Further, the charge amount can be different for each chargeable area. For example, the charge amount may be increased toward the central area of the city, the charge amount may be changed according to the number of times of use, the charge amount may be changed according to the congestion degree,
It is possible to change the charge amount according to the use time and the use time zone, or to change the charge amount according to the traveling distance.
In the following description, the conditions that determine these charge amounts are called calculation conditions for charging (charge calculation conditions). The charging calculation conditions are as follows.

The first billing calculation condition uses the number of times of entry into the area and the traveling distance according to the time zone shown in the table showing the charges for each area in Table 1 below.

[0047]

[Table 1] Unit: Yen By setting as above, the number of times of entry and the travel distance (500m
Every time), the charge amount increases.

The second billing calculation condition uses the area stay time shown in the table showing the charge for each area, and the third billing calculation condition uses the area congestion degree shown in the table showing the charge for each area. However, the fourth charging calculation condition uses the vehicle speed (may be the average vehicle speed) when traveling in the area indicated by the table showing the charge for each area.

By including at least one of the tables based on the above-mentioned charging calculation conditions in the charging information, it is possible to specify the area and the charge for the charging target area.

Next, the operation of the vehicle-mounted device 30 will be described.

As shown in FIG. 6, in the vehicle-mounted device 30 attached to the vehicle, the following interrupt processing is executed every predetermined time (1 minute in this embodiment), and in step 400, the ground side, that is, the general center 40. Receive information from. As described above, the information from the general center 40 is the billing information and the GPS correction information, and it is judged whether the information received in the next step 402 is the latest information. If the information is the latest information, Affirmative in step 402, data representing the charging target area Area is derived from the charging information received in the next step 404, and the received charging information and GPS correction information are stored in the memory 23.
0 is stored in the storage area 230A.

On the other hand, when the received information is not the latest information, it is denied in step 402, the next step 406 receives the GPS signal from the GPS satellites 20, 22, 24, and the next step 408 shows the present information. The date and time (year, month, day, and time) are read, and in the next step 410, the position of the vehicle itself, that is, the current position of the vehicle 32 (latitude / longitude P).
(T)) is calculated. When the latitude / longitude P (t) is obtained, the previously stored GPS correction information can be used.

At the next step 412, the obtained latitude and longitude P
The area to which the latitude / longitude P (t) belongs is determined in the next step 414 by associating (t) with a previously stored map database. In this step 414, the information read from the storage area 230A of the memory 230 is used. Next, in step 416, the latitude / longitude P (t),
The date and time t and the area are stored as a vehicle existence history. Table 2 below shows an example of a list of vehicle existence histories.

[0054]

[Table 2] The "billing" column in the above table is an identifier indicating whether or not the billing process described below has been performed, and the "*" mark indicates that the billing process has been performed. .

As described above, the vehicle 32
The area in which was present is stored as a history together with the date and time.

Next, the billing process in the vehicle unit 30 will be described. The billing process is executed every predetermined time. This predetermined time is executed at a predetermined date and time such as every hour, a predetermined day of the week, a predetermined day and time of each month, and a predetermined year, month and day. The charging process may be executed by an instruction from the general center 40 side.

As shown in FIG. 7, in step 420, it is determined whether or not the conditions are matched by determining whether or not the predetermined date and time or an instruction from the general center 40 side is given. If the conditions do not match,
When the result in step 420 is negative, this routine ends.

On the other hand, if the conditions match, step 4
If the result is affirmative (20), the history information is acquired in step 422. This history information is stored in step 416 of FIG.
3 is a list of vehicle existence histories stored in (Table 2). In the next step 424, an arithmetic expression (billing calculation expression) is set. The arithmetic expression is determined by the above-mentioned arithmetic conditions. This calculation condition refers to a condition for determining the charge amount (charge calculation condition), and includes the number of times the vehicle has entered the area and the travel distance according to the time zone. The charge calculation formula is determined by the calculation conditions. In the following formula (1), the charging calculation formula is shown as a general formula considering the area.

(Charging amount) = f (N _A , N _B , N _H , N _I , N _J , t) (1) However, N _A , N _B :: Evaluation for areas A and B (billing Number of times of approach and mileage for each area determined by the calculation conditions) N _H : Congestion degree N _I : Vehicle speed (average vehicle speed) N _J : Stay time t: Date and time Use to calculate charges. For example, the first charge is determined by the number of times the area enters and the distance traveled according to the time zone.
In the case of the charging calculation condition of No. 3, the table read from the memory 230 determines the number of approaches and the unit price of the traveling distance for each 500 m according to the time zone of each area.
Multiply the unit price of the number of times of entry of the table read from 0 by the number of times of entry, and add the value obtained by multiplying the multiplied value by the unit price of the mileage of every 500 m divided by the mileage of 500 You can calculate the charge. When the charge calculation is completed, the process proceeds to step 428, and the charging process is performed. This billing process is a process of subtracting the above-mentioned billing amount from the balance of the IC card 232.

For example, when the calculation condition is only the number of times of area entry, and the history information is from the starting point STP to the ending point EDP as shown in FIG. 5, the route is Rt0, and the area B is 1. If the vehicle travels 0 km and area A for 1.5 km, the charge amount is as follows.

Rt charge amount = 80x1 + 40x (1000/500) + 60x1 +
30x (1500/500) = ¥ 310 Next, the operation of the in-vehicle device and the ground side equipment while the vehicle is running,
Further description will be made. It should be noted that in the following description, a case will be described in which the fare changes depending on the number of times the vehicle has entered the charging target area and the traveling distance for each 500 m.

As shown in FIG. 8, when the power of the vehicle-mounted device is turned on, the process proceeds to step 500, and the area where the vehicle currently exists is determined. This step 500
The area determination process described above is executed (FIG. 6). In the next step 502, it is determined whether or not the area determined in step 500 is the charging target area. If the area is the charging target area, the affirmative determination is made in step 502 and the next step 504.
Then, it is determined whether or not the previous area is the charging target area (the area determined when the present routine was last executed).
If the previous area is not the chargeable area, it means that the chargeable area is first entered.
If the answer is NO in step 4, the charging area entry process is executed in the next step 506, and the flow advances to step 516. This billing area entry processing is processing performed when the vehicle enters the billing target area, and displays that the vehicle has entered the display device 224. On the other hand, when the previous area is the chargeable area, the affirmative determination is made in step 504, and the process directly proceeds to step 516.

Step 502, not the current chargeable area
If the result is negative, the process proceeds to step 508, and it is determined whether or not the charging target area is approaching. For example, as shown in FIG. 5, the determination as to whether or not the vehicle is approaching is performed up to the charge target area in the straight traveling direction of the vehicle 32 (direction of arrow S in the figure) and the left and right directions substantially orthogonal to the straight traveling direction. The distance a and the distance b are measured, and it is determined whether or not the measured distance is within a predetermined distance. This makes it possible to determine whether or not the charging area exists within the predetermined area. Not limited to the straight-ahead direction and the left-right direction, an area for determining whether or not the distance is within a predetermined distance may be a range of 45 degrees on both sides centering on each direction.

If the distance to the chargeable area is within the predetermined distance, affirmative determination is made in step 508 and the following step 5
In step 50, information indicating that the charging target area is approached is displayed as an image or is provided by voice in step 50.
Return to 0. The display content and the like can be changed according to the distance to the chargeable area. For example, as shown in FIG. 9A, the fact that the charging target area is approaching is displayed when the distance to the charging target area becomes equal to or less than the first predetermined distance (preferably about 500 m). In FIG. 9A, a vehicle mark 225 indicating the traveling direction of the vehicle 32 is displayed, and a reference numeral 227 indicating that the charging target area exists in the straight traveling direction and the leftward direction of the vehicle mark 225 is displayed. Further, when the distance to the charging target area becomes equal to or less than the second predetermined distance (preferably about 100 m), the charging target area is further approached (FIG. 9B).
Display as shown in. In FIG. 9B, the reference numeral 227 is inverted to further emphasize the display.

When the result in step 508 is negative, the routine proceeds to step 510, in which it is determined whether or not the previous area is the chargeable area. If the previous area is not the chargeable area,
Return to step 500. On the other hand, when the previous time is the chargeable area, it means that the current chargeable area is left, and therefore the affirmative answer is obtained in step 510, and the next step 51
In step 2, the charge area leaving process is executed and step 5
Proceed to 16. The charge area leaving process is a process performed when the vehicle leaves the charge target area, and displays the fact that the vehicle has left on the display device 224.

In step 516, it is determined whether or not the power supply of the vehicle-mounted device is cut off. If the power supply is still on, the determination in step 516 is negative, and the process returns to step 500. On the other hand, when the power is cut off, affirmative determination is made in step 516,
This routine ends.

Therefore, the waypoint PS on the route Rt0 in FIG.
In step 1, in step 514, information on the approach of the charging target area is provided. For example, as described above, when the distance to the charging target area becomes equal to or less than the first predetermined distance, the fact that the charging target area is approaching is displayed as shown in FIG. 9 (A). Then, it is displayed as shown in FIG. 9 (B) that the charging target area is further approaching at the waypoint PS2 when the distance to the charging target area becomes equal to or less than the second predetermined distance. Therefore, it is possible to easily recognize that the charging area is further approached. The highlighting is not limited to inversion, and may be emphasized by blinking or changing colors.

Further, the display device 224 can provide information by superimposing and displaying the chargeable areas A and B on the navigation image. For example, as shown in FIG. 10, the road in the charging target area A is displayed with different colors and brightness, and the charging target area name is displayed.
The charging target area name can be displayed in a shaded manner and the charging target area name can be displayed. In addition, as shown in FIG. 10, the distance to the charging target area (straight line distance or shortest route distance) is displayed,
The billing amount may be displayed, or these display contents may be guided by voice. The color, brightness, and shading may be changed according to the approach distance, or may be changed according to the charge amount.

As described above, since it is possible to easily recognize that the vehicle is approaching the chargeable area, the driver can easily select the optimum route. For example, in FIG.
As shown in, charging target areas A and B at the midpoint PS1
When it is indicated that the vehicle is approaching, the route is changed from the originally planned route Rt0 to the route Rt1 shown by the dotted line in the figure, so that only the charging target area A is passed to reach the end point EDP. Therefore, it is possible to avoid unnecessary charges.
