2. Description of the Related Art Conventionally, an in-vehicle radio mounted on a vehicle has been conveniently used as a means for obtaining various kinds of information such as traffic congestion information in a room of a vehicle traveling on a road. This on-vehicle radio is used for entertainment by selectively receiving AM or FM broadcast waves provided by a plurality of broadcasters and listening to a music program, for example, while being used on the road. It plays an important role in avoiding traffic jam roads by obtaining traffic jam information.

By the way, recently, provision of an FM data multiplex broadcasting service for broadcasting by superimposing various additional information such as traffic jam information on FM broadcast waves is being developed. According to this FM data multiplex broadcasting, it becomes possible for the user to obtain more convenient information than before. This will be explained by taking an example of obtaining traffic jam information between the Tokyo and Atsugi interchanges on the Tomei Expressway by FM data multiplex broadcasting. First, the vehicle on the receiving side is composed of various members described below. An FM multiplex data receiving device is installed in advance. That is, a reception antenna, an FM broadcast receiver that receives an FM broadcast wave containing FM multiplex data via the reception antenna, an FM multiplex data decoder that extracts FM multiplex data from the received FM broadcast wave, and an extracted FM. An FM multiplex processing device that restores the character or graphic code contained in the multiplex data to the original character or graphic data, and the restored character or graphic data to bitmap data, and also the converted bitmap data. An FM multiplex data receiving device including a drawing LSI for outputting as a video signal in the form of RGB signals and a display for displaying characters and figures received by inputting the video signal on the screen is prepared in advance. Then, the broadcaster, which is the transmitting side, superimposes the road information in the form of a digital signal composed of a combination of characters and graphics on the conventional FM broadcast wave and broadcasts it. In response to this, if the occupant in the passenger compartment performs a screen selection operation according to a predetermined procedure, on the display of the FM multiplex data receiving device mounted on the vehicle, as road information between the Tokyo and Atsugi interchanges on the Tomei Expressway For example, information such as congestion around the Yokohama Interchange is displayed on the screen in the form of simple graphic data, and passengers in the passenger compartment can visually check this road information to avoid the congested route. Alternatively, it is possible to make an appropriate decision such as taking a break in the service area until the congestion is resolved.

There is a problem to be solved that it is difficult for the driver or the passenger sitting in the passenger seat to immediately obtain a useful information screen.

More specifically, in the conventional screen selection device, as shown in FIG. 4, among the road information databases having a plurality of hierarchical data structures, for example, Tomei Expressway Tokyo / Atsugi. In order to selectively obtain road information between interchanges, a numeric keypad for inputting a numerical number and a decision key for confirming the corresponding selection candidate screen input by the numeric keypad are provided. In order to obtain a useful information screen for the own vehicle, the passenger in the passenger compartment first attaches the heading information for the relevant information screen while looking at the main menu screen displayed on the display. Read the number and enter the number on the numeric keypad. Specifically, from the general roads, intercity highways, metropolitan highways (Kanagawa), and metropolitan highways (Tokyo) that are listed on the menu bar of the main menu screen, they are added at the beginning of the intercity highways. Enter the numeric value on the numeric keypad. Then, the main menu screen displays a list of Tomei Expressway, Kanetsu Expressway, ...
The submenu screen is switched and updated. Here, from among these, enter the numerical number attached to the beginning of the Tomei Expressway using the ten keys. Then, the first submenu screen is
It is switched to the second submenu screen that lists Tokyo, Atsugi, Atsugi, Gotemba, Gotemba, Yaizu, etc. that are subordinate to the Tomei Expressway and is updated. Here, from among these, the numerical number attached to the head of Tokyo and Atsugi is input with the ten keys. Then, the second sub-menu screen is switched and updated to the information screen displaying the traffic congestion information between the Tokyo and Atsugi interchange on the Tomei Expressway in the form of simple graphic data. As described above, the information screen useful for the own vehicle is obtained through the plurality of selection operations according to the depth of the hierarchy.

However, when the occupant in the passenger compartment tries to obtain a useful information screen by the conventional screen selection procedure described above, the useful information located at the bottom of the road information database having a plurality of hierarchical data structures is useful. In order to select the appropriate road information, read the numerical number attached to the beginning of the heading information on the relevant information screen as many times as the number of times depends on the depth of the hierarchy in which the relevant road information is located, You have to repeat the work of entering the numeric keypad,
This work is quite complicated, and it takes a relatively long time to display a useful information screen, so it is difficult to immediately obtain a useful information screen, and in order to solve these problems, There has been a strong demand among the parties concerned to simplify the conventional complicated screen selection procedure.

The present invention has been made in view of the above situation, and greatly simplifies the screen selection operation procedure when displaying an information screen showing the information to be obtained on the display device, and obtains it from the navigation device. A screen selection method for a vehicle-mounted FM multiplex data reception device capable of significantly improving screen selection operability and convenience by immediately displaying road information useful for the vehicle estimated from the progress situation such as the current position. , And a screen selection device.

The remote controller 15 is provided with a ten-key pad (not shown) for inputting a numerical number attached to the head of the heading information for a plurality of information screens, and for confirming the corresponding heading information input by the ten-key. A decision key (not shown), the current position of the own vehicle acquired from the navigation device described below (hereinafter referred to as GPS), the type of road currently running,
And a special key (not shown) for selecting a GPS interlocking mode for displaying useful road information estimated from the progress situation such as the current position in response to the progress direction.
The type of road means the type of road, for example, a highway or a general road.

Further, the CPU 9 uses the data such as the turning angle, the heading, and the moving distance of the own vehicle from various sensors and the map data to present the current position of the own vehicle, the type of the road currently running, and the A GPS 16 that obtains the traveling direction and transfers the obtained progress status such as the current position to the CPU 9.
Is connected. In response to the progress status of the host vehicle transferred from the GPS 16, the CPU 9 gives high priority to useful road information estimated from the progress status of the host vehicle in the GPS interlocking mode in which the special key is operated. By gradually updating and displaying the information screen from one side, the screen selection operability and convenience are improved.

Specifically, among a plurality of programs having various road information provided via FM multiplex broadcasting, road information estimated to be useful from the progress of the own vehicle is sorted by priority. In order to classify and list, for example, as shown in FIG. 3, road type information about the road type of road information provided by a certain program and provided by a certain program in association with each of a plurality of programs. Area range information that represents the area range to which each road information belongs in the form of latitude and longitude is registered in advance, and these registration data are stored in a predetermined address of the RAM 13.

The area registration data is the G according to the present invention.
It can be obtained from the supplier who provides the PS interlocking mode service or can be acquired by registering on the user side. When registering the area registration data on the user side, of the map data supplied from the GPS 16, a peripheral map of the road to be registered is displayed on the display 19 and the area range where the corresponding road extends. By designating both the latitude and longitude directions, it is possible to acquire the regional range registration data of the corresponding road. In addition, the information about the program being broadcast is

In addition, a program that provides information about roads that do not match the road type that is currently running is listed as a semi-priority display target and sequentially displayed from the road information with the highest priority. Here, the road information that is the highest priority display target matches the information about the road that is currently running, and the road information that is the semi-priority display target is the information about the road that branches to the road that is currently running. Therefore, the occupant in the vehicle compartment can immediately obtain road information useful for the vehicle by a simple procedure of operating the special key to switch to the GPS interlocking mode.

Next, the operation of the screen selection device of the on-vehicle FM multiplex data reception device according to the present invention will be described in more detail with reference to FIGS.

First, the outline of the FM multiplex data will be described. The FM multiplex data is composed of a hexadecimal code group representing a character or a graphic, and this hexadecimal code group includes a service identification, a program number, and a page. The screens are classified by numbers and the like. This hexadecimal code group is an FM multiplex data receiving device that includes FM multiplex data.
When the broadcast wave is received by the FM multiplex data receiving device, RA
It is sequentially stored at a predetermined address of M13. Therefore, if a page number with a program number with a certain service identification is repeatedly input with the ten keys, the corresponding data is read from the RAM 13 and the information screen belonging to the page number with the program number with a certain service identification is displayed on the numeric keypad. Can be displayed on top. This is the conventional screen selection procedure in the normal mode.

Next, the screen selection procedure according to the present invention will be described in detail. First, an FM broadcast wave containing FM multiplex data is received by the FM multiplex broadcast reception tuner 5 via the receiving antenna 3, and the received FM broadcast wave is received. From the FM multiplex screen data is extracted by the FM multiplex data decoder 7. The FM multiple screen data extracted here is stored in the CPU 9
Once stored in the RAM 13 at a predetermined address via, the preparation for displaying the FM multiplex screen is completed. At this time, the CPU 9 determines whether or not the special key is operated and input (step 1, hereinafter referred to as step S1). If the result of determination in step S1 is that the special key has not been operated and input, the normal numeric key input is repeated to display the information screen desired to be obtained, while the special key is operated and input. In this case, the processing in the GPS interlocking mode described below is executed.

When shifting to the GPS interlocking mode, the CPU 9
Executes a process of inputting the data regarding the current position of the vehicle and the road type on which the vehicle is currently traveling from the GPS 16 (S3). When the latitude and longitude information as the current position and the information about the road type currently traveling are transferred from the GPS 16, the CPU 9 registers the latitude and longitude information and the road type information as a search key and is stored in the RAM 13. While searching the data and listing the programs that provide the information of the roads that exist in the area range including the current position and that match the road type that is currently running as the top priority display target, A process of listing a program that provides information about roads that are in the area range including the position and that does not match the road type that is currently running is displayed as a semi-priority display target (S5, 7). .
Here, the road information targeted for the highest priority display matches the information about the road currently traveling, while the road information targeted for the semi-priority display includes the information related to the road branching to the road currently traveling. Because of the coincidence, the passenger in the vehicle compartment can immediately obtain the road information useful for the vehicle by a simple procedure of operating the special key to switch to the GPS interlocking mode.

The programs to be displayed which have been listed and prioritized in steps S5 and S7 are:
Characters or graphic data included in the corresponding program data are read from the RAM 13 in order from the program with the highest priority, and the drawing LSI 17 converts the character or graphic data into the bitmap data. In the VRAM built in the drawing LSI 17, the bitmap data that is developed and accumulated in the display form on the display 19 and appropriately read from this VRAM is output as a video signal in the RGB signal form. An information screen composed of characters and figures received by inputting this video signal is displayed on the display 19. In addition, as a method of prioritizing, when there are multiple section information on the road currently running, or when there are multiple roads connecting and branching to the road currently running, the area range close to the current position The priority of the section or road information belonging to is increased, and the priority is decreased as the distance from the current position increases. For example, let's take an example where your vehicle is driving near the Kawasaki Interchange on the Tomei Expressway.The program that displays the section information screen between Tokyo and Atsugi is given top priority, and the order between Atsugi and Gotemba and between Gotemba and Yaizu is the highest. To lower the priority. However, if your vehicle is driving near the Numazu Interchange on the Tomei Expressway towards Nagoya, the information about the sections between Tokyo and Atsugi and between Atsugi and Gotemba is no longer needed, but the current position is If the priority is determined based on the distance from, unnecessary section information is also displayed. Therefore, the traveling direction is additionally adopted as the information obtained from the GPS, and the road information in the direction opposite to the traveling direction is deleted based on the current position of the host vehicle, the road type information currently traveling, and the traveling direction. Thus, it is also possible to list up programs that provide useful section or road information and prioritize these programs. By doing so, it becomes possible to narrow down the programs to be listed up, and only useful road information can be displayed on the screen of the display 19, which contributes to further improvement in convenience. When displaying programs with different priorities in succession, the display time of one program is set to, for example, 5 seconds, and when the set time is exceeded, information is automatically added to the program information belonging to the next priority. The screen can be switched. Also, by installing a separate update prohibition switch that prohibits display updates of programs,
When the update prohibition switch is operated while displaying certain program information, the program information displayed at this time can be continuously displayed.

As described above, the screen selection mode is switched to the GPS interlocking mode by the operation input of the special key instead of the conventional selection of the information screen by the ten-key input, and the information on the road currently running is given the highest priority. Since the information about the road connecting and branching to the road currently running is given priority to be displayed sequentially from the road information with the highest priority, the passenger in the passenger compartment operates the special key to input G.
By the extremely simple procedure of switching to the PS interlocking mode, road information useful for the vehicle can be immediately obtained, and operability and convenience at the time of screen selection can be significantly improved.

In the present embodiment, the mode in which the special key is operated to switch to the GPS interlocking mode has been illustrated, but the present invention is not limited to this, and conversely,
It is also possible to set the GPS interlocking mode to the standard mode and switch to the screen selection procedure by the ten-key input in response to the operation input of the mode switching key for switching to the normal mode.
