Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system for toll roads and an on-vehicle device for toll collection used in this toll collection system.

[0002]

2. Description of the Related Art An AFC (Automatic Fee Collection) system is currently proposed as a method of a toll collection system for toll roads. In this system, an in-vehicle device is installed in a vehicle, a roadside device is installed at a tollgate on the ground side, and data necessary for collecting charges is exchanged between the onboard device side and the roadside device side.

The applicant of the present invention has already disclosed an invention relating to an in-vehicle device when a cashless system is applied to the above AFC system in Japanese Patent Application No. 56-96868 (Japanese Patent Publication No. 02-23).
No. 907) and Japanese Patent Application No. 61-188324 (Japanese Patent Publication No. 06-70804).

These on-vehicle devices are shown in FIGS. 19 (a) and 19 (b).
It is configured as shown in FIG. In the figure, numeral 1 is a toll collection terminal main body, on the surface of which a display section 2 and a keypad 3 are provided. In addition, the card insertion slot 4 on the top
Is formed, and the transmitting / receiving antenna 5 is incorporated inside the back surface. The display unit 2 displays information received from a roadway device installed at an entrance or an exit of a toll road or on the way and information to be transmitted to the roadway device. The keypad 3 is composed of numeric keys 0 to 9 and various function keys, and is used to input a personal identification number. An IC card used as a cashless such as a bank card or a credit card can be inserted into the card insertion slot 4. The transmitting / receiving antenna 5 is for transmitting data to and from the roadside device by wireless communication means.

The above-mentioned on-vehicle device can be manufactured in a compact size and can be attached to all vehicles by a simple operation. Considering the convenience of the user, it is optimal at present. It is determined to be In particular, even if the AFC system is applied to the toll collection system, the AEC system is not applied to all vehicles, so only the necessary vehicles to be applied to the AFC system,
It can be said that the above vehicle is excellent in terms of convenience because it is not necessary to install these vehicle-mounted devices in a vehicle to which the vehicle-mounted device is mounted and cash payment is desired. Further, as described above, the card insertion slot 4 has a versatile I
Since the C card is detachably provided, the IC card can be used for a bank card, a credit card, a prepaid card and the like, and can be applied to a system other than the charge collection.

On the other hand, considering the recent electronics technology of automobiles, the car navigation market is expanding rapidly. With the entry of new manufacturers into the rush of new products, the competition for market share of each company is intensifying. In 1995, it sold 500,000 units and 2000 units.
The market is expected to expand to 2 million units a year (Nikkan Kogyo Shimbun 1995 (Heisei 7) 5
Published on the 22nd of the month). Two million is 20% of all vehicles owned in Japan.

The car navigation system is currently commercialized as one means of using automobile electronics, and the GPS (Global Positioning System) that can be used for a toll collection system or the like is used for this purpose.
) Has been introduced. At present, more than 20 GPS satellites have been launched for military use in the United States, which is used to measure the position of a traveling vehicle.

The Applicant was quick to pay attention to this and
An invention relating to a toll collection system using a PS satellite has already been filed in Japanese Patent Application No. 06-235213. The purpose of the present application is to position the passing vehicle by GPS,
As a result, it is possible to find out where the passing vehicle has traveled, and therefore, an attempt is made to collect an automatic toll on the toll road.

The relationship between the toll collection system and the navigation system of the vehicle has been described above. However, it is expected that the on-board unit integrated with the vehicle will become the mainstream of future in-vehicle units. The system incorporated in is considered to be the most viable system.

[0010]

The possibility of a system centering on a navigation system will be described in detail below. We anticipate that the vehicle navigation system and the infrastructure of car electronics that has developed this system will advance, and that the GPS satellite position measurement system will not exist in the era when it depends on one country's military satellites The collection system (currently planned AFC system) must be further developed.

In order to realize this, the car navigation system 21 as shown in FIG. 1 and the current toll collection system 22 are combined and further developed, and as shown in FIG. It is necessary to construct a system in which the toll collection system 22 and the wireless telephone system 23 are combined. Here, in order to realize this system, the following two points are raised as major problems.

1. The system must be considered as fully integrated as part of a vehicle component. 2. Some of the above systems should be provided by the business operator of the toll collection system and should be incorporated as part of the parts, but they are sealed by the user and cannot be tampered with. There must be.

Next, considering the situation of toll roads in Japan, the current service section is a little less than 6,000 km (fiscal 1995), but finally, as shown in FIG. The final form of the expressway network is a total extension of 14,000k
It will be m and will form a loop between the roads. In FIG. 6, the Δ mark indicated by the symbol 64 indicates that the road forms a loop.

As described above, when the traveling distance is 14,000 km in total, it is obvious that a loop will occur between roads and it will be difficult to collect tolls according to the distance. Currently, four barriers are installed in Japan, as shown in Fig. 6, namely, Yojima barrier, Yamazaki barrier, Maibara barrier, and Izumi barrier.
Also planned. Here, the toll collection method for connecting between current roads, that is, at the time of passing the main point, a stamp etc. is pressed on the passing card to prove that the passing vehicle has definitely passed the main point. In addition, a method of issuing and operating a transit ticket is adopted. Also in this method, if the total extension distance is 14,000 km, such stop points must be provided at a large number of points, and the installation place of the tollgate must be provided accordingly.

3. Therefore, even if the toll road is formed in a loop as shown in FIG. 6, it is considered that the toll collection under the distance-distance toll system should be smoothly carried out. In a position locating system using GPS satellites, using a general GPS satellite has a limit in measurement position accuracy.
It is necessary to use GPS (Differentical GPS). In this method, the current position of the vehicle is several cm, as will be described later.
It is intended to measure up to the unit of with high accuracy.

4. This method is indispensable for constructing a toll collection (road charging) system in a relatively narrow range. In addition, it is possible to build a parking lot management system in a flat parking lot. 5. Finally, it enables the system to be compatible with the existing tariff system, which is the most important issue of this system.

[0017]

[Means for Solving the Problems] Means for solving the above-mentioned five problems will be sequentially described. That is, regarding the first problem, that is, means for solving the following problems: 1) A system in which a vehicle navigation system and a current toll collection system are completely compatible with each other. It is incorporated as a part of the vehicle parts, is provided by the business operator of the toll collection system in the above system, and is also incorporated as a part of the parts, and is a toll road user. Must be something that cannot be removed and tampered with.

For this reason, an on-vehicle device system as shown in FIG. 3 is proposed. This is an application of the GPS system. That is, in the on-vehicle device system, the car navigation system 21 and the first and second wireless transmission / reception systems 31 and 32 of the fee collection system 22 are connected to each other through interface circuits (I / F circuits) 210 and 34. , And the functions are independent of each other. Further, the car navigation system 21 is connected to a charging condition storage operating unit 24 for storing and reading a condition for charging a traveling vehicle through interface circuits 210 and 241. The charging condition storage operating unit 24 indicates a portion to be sealed by the operator of the toll road. A billing information storage unit 33 is connected to the wireless communication systems 31 and 32 by an interface circuit 331, and as described above,
This section also indicates that the operator of the toll road should seal it.

FIG. 4 shows an example of an in-vehicle device system when a GPS satellite is not used. The difference from the toll road in FIG. 3 is that the toll road is embedded in a beacon or in the ground. It is different from FIG. 3 in that a sensor is provided and a position information receiving circuit for receiving and detecting the sensor is provided, and that there is no charging condition storage operation unit.

FIG. 5 is the same as FIG. 3 in that a GPS satellite is used, but if a general GPS satellite is used, the measurement position accuracy is limited, so the D-GP is used.
It shows an example to which S (Differentical GPS) is applied. This is a method of calculating the position information of the vehicle by determining the error factor that occurs when calculating the position from the GPS information from the fixed point observation data of which the position is known, and correcting the GPS information based on the information. The reason for picking up here is that apart from collecting tolls for the expressway network that spreads all over Japan, toll collection in a relatively narrow area in the city (road charging rather than toll collection is more appropriate) This is because it is a system used to regulate the entry of vehicles into the city).

The on-vehicle device of this method is also applied to a parking lot system (particularly suitable for a flat parking lot) as described later. The above examples are shown in FIG. 3, FIG. 4, and FIG.
The present invention provides a means for solving the problems [1] and [2] that can be realized by the in-vehicle device system shown in FIG.

2) Next, as described above, even if the toll road forms a loop as shown in FIG. 6, in order to normally collect the toll, firstly, the charging condition storage operation in the in-vehicle system is performed. It is to set up a section. Here, the location of the toll road at which the toll should be charged is stored and sealed, and the toll is automatically charged when the vehicle passes through the toll road.

The above example can be realized by the vehicle-mounted device system shown in FIGS. 3, 4 and 5, and provides means for solving the problem [3] to be solved by the invention. 3) Next, as described above, as a method for realizing a road charging system in a relatively small area, the D-GPS is used.
By introducing an in-vehicle device system using (Differentical GPS), a road charging system in an urban area can be realized, and a management system in a parking lot can be realized.

The above example is an example in which the road charging system is introduced in a limited area of the urban area shown in FIG. 8, and as shown in FIGS. 10 and 11, a parking lot management system is installed in a flat parking lot. The introduced example is provided to provide a solution to the problem [4] to be solved by the invention.

4) Finally, consider the system that is compatible with the existing fee system as the most important issue,
The in-vehicle system has a wireless transmission / reception system based on the existing AFC system.

The above examples are shown in FIGS. 3, 4 and 5 for the vehicle-mounted device, and FIG. 15 corresponds to the system of the entire toll road. (Structure and operation) Hereinafter, the structure and operation of the present invention will be described.
