CONSTITUTION:This navigation system provided with a display and with an RACS receiver connected is provided with a name display means for displaying the section name of received information on the display when the signal from the beacon is received by the RACS receiver, and the name display part on the display becomes a switch pad part in a touch switch.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation system, and more particularly to a navigation system having a RACS (road-vehicle information communication system) receiver.

[0002]

2. Description of the Related Art Currently, a road-vehicle information communication system (RACS) is being developed under the guidance of the Ministry of Construction. Road-to-vehicle information communication system is a road beer on major roads nationwide.
When a vehicle equipped with a controller and equipped with a RACS receiver passes under the beacon, information necessary for traveling from the beacon to the driver, for example, current position information,
The system is intended to provide road guidance information and real-time information regarding parking lots, traffic congestion, traffic restrictions, etc. to the vehicle. In the system currently envisioned, as shown in Table 1, about 40 types of large section information including static information and dynamic information are scheduled to be transmitted from the beacon. In Tables 1 and 2, the information of type numbers 1 to 3 is the information transmitted from all beacons, but the information other than the type numbers 1 to 3 depends on the installation location of each beacon. It may or may not be sent.

[Table 2]

[0005]

Although the overall concept of the road-to-vehicle information communication system is considered as described above, various kinds of information to be transmitted from the beacon shown in Table 1 are to be transmitted. At present, no specific selection method of how to select is proposed. In order to operate the road-vehicle information communication system as a part of the navigation system functionally, the user can easily select the required information from the above-mentioned various kinds of information. Must be provided in the system.

The present invention has been made in view of the above problems, and provides a selecting means that allows a user to easily select the required information from among various types of information transmitted from a beacon. It is an object of the present invention to provide a navigation system which is provided with the road-vehicle information communication system as a part of the system and can be functionally operated.

[0007]

In order to achieve the above object, a navigation system according to the present invention is provided with a display, and in a navigation system to which a RACS receiver is connected, a signal from a beacon is displayed. The RACS
When the receiver receives, it is characterized in that a name display means for displaying the classification name of the received information on the display is provided, and the name display section on the display is a switch pad section in the touch switch.

[0008]

In the navigation system according to the present invention, when the information transmitted from the beacon is received by the RACS receiver, the name display means causes the section name of the information to function as a touch switch on the display. It is displayed in the name display section that it has. Then, the user confirms the section name displayed on the name display section on the display, and turns on the name display section on which the required section name is displayed, that is, the touch switch pad section. When the name display section is turned on, the information indicated by the section name displayed on the name display section is displayed on the display. At that time, if the information is properly displayed on the map, it is displayed on the map screen, and if the information is properly displayed on the map, it is displayed in characters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a navigation system according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically showing the configuration of the navigation system according to the embodiment. In FIG. 1, reference numeral 10 indicates a navigation system controller.

Navigation system controller 1
Reference numeral 0 is composed of a main controller 12, a GPS receiver 13, a drawing controller 14 and the like. A CD-ROM 15 is connected to the main controller 12,
An antenna 13a is connected to the PS receiver 13, and a drawing controller 14 is connected to a display 16 such as an LCD. In addition, the main controller 12 has RACS
The receiver 11 is connected, and the RACS receiver 11 is connected to the antenna 11a.

The operation of the navigation system constructed as above will be described with reference to FIGS. 2 and 3. 2 is a schematic diagram illustrating a process of transmitting information received by the RACS receiver 11 and a method of displaying the information on the display 16, and FIG. 3 is a flowchart showing the operation of the main controller 12. -It is.

First, in step 1, it is judged whether or not the information transmitted from the beacon has been received by the RACS receiver 11. If the information is not received, the process proceeds to step 3, and if the information is received, the process proceeds to step 3 via step 2. In step 2, as shown in FIG. 2, the information received by the RACS receiver 11 and transmitted to the main controller 12 is displayed on the name display section 17 on the display 16 by the main controller 12. . For example, when the RACS receiver 11 receives the information of the classification number 1, the name display portion 17a displays “current position A”, and when the information of the classification number 21 is received, the name display portion 17b displays the information. "Traffic information A" is displayed.

In step 3, it is determined whether the name display section 17 is turned on. That is, the display 16
One of the division names displayed above is selected, and the name display section 17 (= switch pad section that is a touch switch) displaying the selected division name is turned on. It will be judged. If it is not turned on, the process proceeds to step 5, and if it is turned on, the process proceeds to step 5 through step 4, and after performing the main processing relating to the navigation, returns to step 1. In step 4, as shown in FIG. 2, the content of the information indicated by the selected section name is displayed on the display 16. For example, if "congestion information A" on the name display portion 17a is selected, a marker black indicating the present position of the vehicle on the map screen and a black mark indicating that the vehicle is in congestion are displayed. Filled □□□ is displayed.

As described above, the navigation system according to the embodiment
In the operation system, when the signal from the beacon is received, the classification name of the received information is displayed on the name display section 17 on the display 16, and the name display section 17 serves as a switch pad section in the touch switch. Because
The user can confirm the classification name of the information provided by the beacon on the display 16, and the name display section 1
By turning on 7, the required information can be selected.

[0015]

As described in detail above, when the navigation system according to the present invention is used, the user can see what type of information is being transmitted from the beacon on the display. It can be confirmed by the classification name displayed on the name display section, and by turning on the name display section which is the switch pad section of the touch switch, the required type of information can be selected.
