BEST MODE FOR CARRYING OUT THE INVENTION

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an on-vehicle navigation device of the present invention. The main processing device 1 is composed of a CPU and the like. The map data reading device 3 is a driver which is controlled by the main processing device 1 and reads map data from an external map database (not shown) such as a CD-ROM. The current position detection device 7 includes a GPS receiver, a direction detector such as a gyroscope, and a speed detector, and detects the current position of the vehicle and the traveling direction of the vehicle.

The ROM 9 stores the traffic regulation types shown in the list of FIG. The ROM 9 also stores symbols for each traffic regulation type, as shown in the list of FIG. 4, in case the external map database does not store symbols corresponding to the traffic regulation type.

The RAM 11 stores the table shown in FIG. 5 as described later. The clock 13 measures the date and time. The display device 15 is an LCD (liquid crystal display device) or CR.
It consists of T (cathode ray tube) etc. and displays map data etc.

First, the operation of registering traffic regulation information will be described. FIG. 2 shows an example of the registration procedure, which will be described with reference to this. Incidentally, ST201 to ST2
Reference numeral 05 represents a step of operation.

At ST201, a traffic regulation type is selected.
Specifically, the main processing device 1 reads the traffic regulation type list shown in FIG. 3 from the ROM 9 and displays it on the display device 15. Traffic restrictions include no entry, one-way traffic,
There are no left turns, no right turns, and no traffic. The operation unit 5 specifies the applicable traffic regulation type from the displayed list. As a result, the main processing means 1 specifies the tape address of the RAM 11 that stores the position or section described later, the restricted direction designation, the period, the time zone, and the title in a linked manner. The ROM 9 also stores the display color for each traffic regulation type as shown in the list of FIG. 12, instead of or together with the symbols of the traffic regulation type shown in the list of FIG.

At ST202, the position or period is input. Specifically, the main processing device 1 reads the map data via the map data reading device 3 and displays it on the display device 15. Next, the operation unit 5 selects a position (place) where traffic regulation exists or a start point and an end point of a section where traffic regulation exists on the map. Depending on the type of traffic regulation, for example, in the case of prohibiting a right turn, the operation means 5 also designates a restriction direction such as from which direction the vehicle is traveling.

Then, the main processing unit 1 has a RAM.
The position or section is stored as the absolute position (longitude and longitude) in the column of the position or section of the corresponding address in the table of 11. Incidentally, instead of the absolute position, other numerical values related to the map database, such as normalized coordinates, node numbers and link numbers may be stored.

When the restriction direction is designated, the main processing unit 1 stores the direction in the restriction direction designation column of the corresponding address in the table of the RAM 11.

Instead of selection on the map of the display device 15, data of the position, section, and regulation direction may be input from the operation unit 5 and stored in the RAM 11.

In ST203, the operation unit 5 is used to input a period (year, month, day) during which traffic control is to be performed. If no period is specified, enter that fact. Then, the main processing device 1 stores the period in the column of the period of the corresponding address in the table of the RAM 11. Note that a plurality of periods can be stored.

In ST204, the operation section 5 is used to input a period band (hours and minutes) during which traffic control is performed. If no time zone is specified (all day restriction), enter that fact. Then, the main processing device 1 stores the time zone in the time zone column of the corresponding address in the table of the RAM 11. A plurality of time zones can be stored.

As shown in FIG. 5, titles can also be linked and stored in the RAM 11. Therefore, in ST205, the title is input. The title may be a place name of a place where the traffic regulation is registered, a character string, a number, or the like. The main processing means 1 automatically takes in the place name of the place where the traffic regulation is registered from the map database, and stores it in the RAM.
It may be stored in 11. Alternatively, the place name of the place may be input by the operation unit 5. The character string or the number is input by the operation unit 5. The main processing device 1 stores in the RAM 11 the place name, the character string, the number, etc.
It is stored in the column of the title of the corresponding address.

By the above, the table of the RAM 11 shown in FIG. 5 is completed. Even when there are two or more traffic restrictions in one place or section (for example, left turn prohibition and right turn prohibition overlap), a table is created for each traffic regulation type.

Next, a first example of the traffic regulation information display operation will be described. Position information is input from the operation unit 5.
The main processing device 1 reads the map data from the external map data via the map data reading device 3 based on the position information, and displays it on the display device 15.

Next, the main processing unit 1 has a period and a time zone corresponding to the date and time measured by the clock 13 and enters the map area displayed on the display unit 15.
Connected traffic regulation type, position, section, regulation direction,
It is read from the table shown in FIG.

Next, the main processing unit 1 reads the traffic regulation type symbol corresponding to the traffic regulation type from the list of the ROM 9 shown in FIG. 4, and displays it on the map data at the position or section. . If the external map database holds traffic control symbols,
The symbol may be read from the map database and displayed. As a result, the image shown in FIG. 6 is displayed on the display device 15.

Alternatively, the main processing unit 1 reads the display color corresponding to the traffic regulation type from the list of the ROM 9 shown in FIG. 12, and displays the position or section in the display color. When the external map database holds the display color of the traffic regulation type, the display color is read from the map database and the corresponding position or section is displayed. As a result, the image shown in FIG. 13 is displayed on the display device 15.

When the selection cursor is moved by the operation unit 5 to specify a point, the main processing unit 1 displays the traffic regulation type, the period, the period zone, etc., which are connected to the position or section corresponding to the point. It is read from the table shown in FIG. Then, the main processing device 1 switches the display of the display device 15 from the image of FIG. 6 or 13 to the character image of the traffic regulation type, the period, and the time zone shown in FIG. 7. The traffic regulation type name, the period, and the time zone may be displayed in an overlapping manner on the image of FIG. 6 or 13 instead of FIG. 7.

Furthermore, when the selection cursor is moved by the operation unit 5 and a point is designated, the main processing unit 1 displays the title connected to the position or section to which the point corresponds.
It is read from the table shown in FIG. Then, the main processing device 1 displays the title in the vicinity of the traffic regulation type symbol or display color already displayed as shown in FIG. 6 or FIG.

The main processing means 1 terminates the display of the traffic regulation type symbol or display color after a predetermined time. Alternatively, the main processing device 1 ends the display of the symbol or the display color of the traffic regulation type that does not correspond to the date and time measured by the clock 13.

Next, a second example of the traffic regulation information display operation will be described. The main processing device 1 reads the map data from the external map database via the map data reading device 3 based on the current position of the vehicle, and the display device 1
5 is displayed.

Then, the main processing unit 1 has a period and a time zone corresponding to the date and time measured by the clock 13, and is connected within a predetermined range around the current position. The traffic regulation type, the position, the section, the regulation direction, etc. are read from the table of the RAM 11 shown in FIG.

Next, the main processing unit 1 reads the traffic regulation type symbol corresponding to the traffic regulation type from the list shown in FIG. 4 of the ROM 9 and displays it on the map data at the position or section. . If the external map database holds a symbol of traffic regulation type, read the symbol from the map database,
You may display it.

Alternatively, the main processing unit 1 reads the display color corresponding to the traffic regulation type from the list of the ROM 9 shown in FIG. 12, and displays the position or section in the display color. When the external map database holds the display color of the traffic regulation type, the display color is read from the map database and the corresponding position or section is displayed in the display color. As a result, on the display device 15,
The image shown in FIG. 14 is displayed.

Incidentally, the name of the traffic regulation type connected to the point or section of the symbol of the traffic regulation type, the period information,
The time zone information and the like can be displayed in characters by the procedure described above.
Further, the title connected to the point or section of the symbol of the traffic regulation information can be displayed by the procedure described above.

Further, the main processing unit 1 can terminate the display of the symbol or the display color of the traffic regulation type at the point where the vehicle is separated from the predetermined range around the current position of the vehicle.

Next, a third example of the traffic regulation information display operation will be described. This third example is shown in FIG.
The display of the symbol of the traffic regulation type is restricted based on the memory of the regulation direction designation field of the table shown in and the traveling direction of the vehicle.

Description will be made with reference to the display example shown in FIG. At intersection C, right turn prohibition when going from point A to point B and left turn prohibition when going from point B to point A,
Suppose each is registered. Vehicle is at point A
When heading to the point B from the main processing unit 1,
RAM and the traveling direction of the vehicle detected by the current position detection device 7
11 is compared with the restriction direction designation at the intersection C, and the traffic restriction type only for the right turn prohibition and the position of the intersection C are read from the table of the RAM 11 in FIG. Then, the main processing means 1 reads the right turn prohibited symbol from the list of the ROM 9 shown in FIG. 4 or from the external map database and displays it at the position of the intersection C.

Alternatively, as shown in FIG. 15, since the right turn is prohibited at the point C, the section CD cannot be entered. Therefore, the main processing device 1 displays the section CD in a color different from the colors of the background and other roads. Also, as shown in FIG.
The section CD may be displayed in the same color as the background and the road itself may be erased as if there is no road.

Further, regardless of the registered contents of the table shown in FIG. 5, it is possible to select the display of the traffic regulation type symbol or the like on the display device 15. Specifically, the main processing device 1 reads the contents of the table of FIG. 5 of the RAM 11 and displays it on the display device 15. The display device 15
5 cannot display all the contents of the table shown in FIG. 5, and the list of traffic regulation types shown in FIG. 10 or the list of titles shown in FIG. 11 is displayed. Then, the operation unit 5 is used to move the cursor to specify what is desired to be displayed or what is not to be displayed.

The operation of displaying the traffic regulation information is not limited to the one described above.

It should be noted that this traffic regulation information is R when the automatic route is set.
It can also be imported from the AM 11 and reflected in the route setting.

Next, the operation of deleting the traffic regulation information once registered in the table of the RAM 11 shown in FIG. 5 will be described.

First, the case where the navigation device automatically performs will be described. The main processing unit 1 has a clock 13
With reference to the date measured by, the traffic regulation information whose period has passed is deleted from the table of the RAM 11 shown in FIG.

Next, the case where the user specifies will be described. The traffic control classification symbol on the displayed map is designated with the cursor by the operation unit 5. Then, the main processing device 1 outputs the traffic regulation information regarding the position or section to the RA.
It is deleted from the table of M11 shown in FIG.

As another method designated by the user, the main processing unit 1 reads the table of the RAM 11 shown in FIG. 5, and displays it on the display unit 15 as shown in FIG. 10 or 11.
Display a list of registered traffic regulation types or a list of registered titles. Next, the operation unit 5 is used to move the cursor and specify the item to be deleted. Then, the image of the display device 15 is switched to the image of the map on which the symbol of the relevant traffic regulation type is displayed. When the user confirms this image and the user gives an instruction to execute the deletion through the operation unit 5, the main processing device 1 deletes the traffic regulation information from the table of the RAM 11 shown in FIG.
