Abstract

PURPOSE:To display detailed information of an object facility instead of a map by displaying detailed related information of a final target object, when a specific density object corresponds to the final target object, and superposing a position of the object facility on the displayed map. CONSTITUTION:An operating means M3 outputs a limiting command for showing a limiting condition of a display object group displayed on a display means M2 to a display control means M4. The means M4 superposes position information for displaying a geographical position in map information of the display object group corresponding to the limiting command, onto the map information which has been inputted from a map information storage means M1 and transfers it to the means M2. On the other hand, the means M3 outputs the command concerned for showing a fact that a specific display object corresponds to a final target, to a selecting and display means M7. The means M7 works so that detailed related information of the final target object which has been determined, based on a geographical position of a target object which has been retrieved by a retrieving means M5 is selected and inputted from related information which has been stored in a related information storage means M6, and its display information is transferred to the means M2.

Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Field of Application] The present invention is a method for displaying detailed related information regarding destinations, facilities, etc. on a map displayed on an in-vehicle navigation device, etc. The present invention relates to an in-vehicle information display device.

[Prior Art] Conventionally, for example, maps, expressway diagrams, etc. are stored in an on-vehicle device in advance, and based on the geomagnetic direction and travel distance,
2. Description of the Related Art A so-called navigation device is known that displays the current location, direction of travel, and route to a destination of a vehicle, as well as the locations of various facilities on a map. For example, the following techniques have been proposed as such techniques. In other words, (1) an "in-vehicle navigation device" (specially designed Publication No. 194475/1983).

(2) As map information, predetermined facilities such as hotels, parking lots, gas stations, dealers, etc. are displayed as symbols at the locations where the facilities are located, superimposed on the road, and
"Information display device" that displays relatively simple numbers, letters, symbols, etc. that are mutually distinguishable and continuously related to each of the symbols representing the same type of facilities (Japanese Patent Application Laid-open No. 1983-1999)
-151884).

[Problems to be Solved by the Invention] However, the conventional technology has a problem in that it is only possible to display the location of related facilities on a map or information about related facilities that can be expressed using relatively simple symbols.

For example, when the driver or passenger of a vehicle is driving in a geographically unfamiliar place, even if multiple locations of related facilities such as hotels and extremely small information are displayed on a map, it may be difficult for the driver or passenger to In many cases, it is not possible to provide the necessary information, and the display function has not yet been fully demonstrated.

Furthermore, even if the operator selects a related facility by operating a touch sensor, etc., what can be grasped is limited to the location of the related facility, and the type and degree of information cannot be selected according to the operator's intention. There was also room for improvement in operability and functionality.

An object of the present invention is to provide an on-vehicle information display device that can suitably display information that matches the type and hierarchy selected by a vehicle occupant regarding facilities on a map displayed on an on-vehicle display.

1 Bean L 1 Plate [Means for Solving the Problem] The present invention, which has been made to achieve the above object, as illustrated in FIG. a display means M2 for displaying display information to be displayed; at least a limiting command indicating a limiting condition for a group of display objects to be displayed on the display means M2; and a target indicating a target object selected from the group of display objects corresponding to the limiting condition. an operating means M3 for outputting a command and a corresponding command indicating that the specific display target corresponds to the final target object; In addition to superimposing position information that displays the geographical position of the display target group in the above map information, when the display target group is not commanded from the outside, predetermined conditions are applied; on the other hand, when the display target group is commanded from the outside, a display control means M4 for transmitting display information for displaying a specific display object selected from the display object group in accordance with the command so as to be mutually distinguishable from other display objects to the display means M2; Searching for a display object corresponding to the geographical position of the target object according to the target command output by the operating means M3 from the display object group displayed superimposed on the map information, and setting the specific display object to the target object. a search means M5 that outputs a command to change to the display control means M4; and a related information storage means that stores detailed related information related to the display target group included in the map information stored in the map information storage means M1. M6 and when the operating means M3 outputs the corresponding command, the related information of the final target object determined based on the geographical position of the target object searched by the searching means M5 is stored in the related information storage means M6. The gist of the present invention is an in-vehicle information display device comprising: selection display means M7 for selectively inputting stored related information and transmitting display information for displaying the related information to the display means M2; It is something.

[Function] As illustrated in FIG. 1, in the in-vehicle information display device of the present invention, the operating means M3 sends a limiting command to the display controlling means M4 indicating the limiting conditions for the display target group to be displayed on the displaying means M2. Output. Then, the display control means M4 superimposes and displays position information indicating the geographical position in the map information of the display target group according to the restriction command on the map information input from the map information storage means M1. The information is transmitted to the display means M2. Moreover, the display control means M4
Among the above display target groups, when there is no command from the outside, the specific display target selected from the above display target group is set according to predetermined conditions, and when it is commanded from the outside, according to the command, respectively. The display information to be displayed so as to be distinguishable from the display target is transmitted to the display means M2. Further, the operating means M3 outputs a target command indicating a target object selected from the group of display objects corresponding to the above-mentioned limiting conditions to the search means M5. Then, the above-mentioned search means M5 searches the above-mentioned display means M2.
From the display target group displayed superimposed on the map information,
A display object corresponding to the geographical position of the target object according to the target command output by the operating means M3 is searched for, and a command to change the specific display object to the target object is output to the display control means M4. Roughly speaking, the operating means M3 outputs a corresponding command indicating that the specific display object corresponds to the final target object to the selection display means M7. Then, the selection display means M7 converts the detailed related information of the final target object determined based on the geographical location of the target object searched by the search means M5 into the related information stored in the related information storage means M6. , and transmits display information for displaying the related information to the display means M2.

In other words, a specific display target searched according to the target command can be distinguished from other display targets from a group of display targets that are limited according to the restriction command and whose geographical locations are superimposed on map information. When the specific display target corresponds to the final target target, detailed related information of the final target target is displayed.

Therefore, the in-vehicle information display device of the present invention works to display detailed related information of the final target selected by the vehicle occupant on the displayed map instead of the map.

The technical problems of the present invention are solved by each component of the present invention acting as described above.

4. IC that records detailed information that is also updated/added
It is composed of an IC card reader/writer 26 for reproducing the card 25.

The ECU 3 is configured as a logic operation circuit mainly including a CPU 5a, a ROM 5b, and a RAM 5c, and is connected to a human output section 5e via a common bus 5d to perform human output with the outside. Signals from each switch and each key from the operating section 2 and reproduction signals from the stored information reproducing device 3 are sent to C via the human output section 5e.
The signal is input to the PU 5a, and the CPU 5a outputs a control signal via the human output section 5e to drive and control the information reproducing device 3 and display 4. Furthermore, the ECU 3 is a human output section 5e.
Data communication is performed with the navigation computer 7 via the navigation computer 7.

Next, the information display process executed by the ECU 3 is shown in FIG.
) and (2). The information display process is started when the ECU 3 is started. First, in step 100, a process of reading a switch signal is performed. In the following step 105, step 1
It is determined whether the switch signal read in step 00 is a menu signal or not. If the judgment is affirmative, the process proceeds to step 130, and if the judgment is negative, the process proceeds to step 110.

In step 110, which is executed when a switch other than the menu switch 12 is operated, it is determined whether the switch signal read in step 100 is a map signal or not, and if an affirmative determination is made, the process proceeds to step 115; on the other hand, if a negative determination is made, the process proceeds to step 115. and returns to step 100. In step 115, which is executed when the map switch 13 is operated, processing for determining a display map is performed. The displayed map may be determined according to manual instructions from the operation unit 2, or may be determined according to vehicle current position information transmitted from the navigation computer 7. In the subsequent step 120, a process is performed to output a control signal for searching and reading map data related to the map determined in step 115 to the compact disc player 22 of the stored information reproducing device 3. Next step 125
The process proceeds to step 120, in which a control signal for displaying a map on the screen is output to the display 4 in accordance with the searched map data, and then the process returns to step 100.

On the other hand, in step 130, which is executed when the menu screen/border 12 is operated, a process of outputting a control signal for displaying the menu screen to the display 4 is performed. In the following step 135, a process of reading the switch signal is performed.

Next, the process proceeds to step 140, and it is determined whether the display information hierarchy has been determined based on the switch signal read in step 135. If the judgment is affirmative, the process proceeds to step 150; on the other hand, if the judgment is negative, the step 145, respectively.

In step 145, which is executed when the display information hierarchy is not determined yet, the display information hierarchy changing process is performed, and then the process returns to step 130 again. That is, when the menu switch 12 is operated for the first time, the display 4 shows "Information Display Selection" which is a high-level display information hierarchy, as shown in FIG.
A menu screen is displayed. The operator presses cursor key 1.
When a menu is selected using 1U or 11D, some of the selected items blink as shown in the figure. Here, when the operator operates the set switch 14, the display information hierarchy is determined to be a high level. Meanwhile, the operator presses return switch 1
5, the display information hierarchy change process causes the display 4 to display the "Tourism" menu screen, which is the middle display information hierarchy, as shown in FIG. Thereafter, depending on the operator's switch operation, the display information hierarchy is similarly determined to be the middle level, or as shown in FIG. Changes to the "Park" menu screen.

When the display information hierarchy is determined by repeating such display information hierarchy change processing, control proceeds from step 140 to step 150. In step 150, a process is performed to determine a display target facility (for example, a park, etc.) based on the determined display information hierarchy. In the following step 155, processing for determining a display map is performed. This display map is determined according to either a manual instruction from the operation unit 2 or vehicle current position information transmitted from the navigation computer 7. In the following step 160, a process is performed in which a control signal for searching and reading map data related to the map determined in step 155 is output to the compact disc player 22 of the stored information reproducing device 3.

Next, the process proceeds to step 165, in which a control signal for displaying a map on the screen is output to the display 4 according to the map data retrieved in step 160. In the subsequent step 170, a process is performed in which the location of the facility to be displayed determined in step 150 is superimposed and displayed on the map displayed in step 165 using symbols such as various predetermined symbols.

Next, the process proceeds to step 175, in which a process of selecting the symbol closest to the center of the screen from among the symbols currently displayed on the screen of the display 4 is performed. In the following step 180, the symbol selected in step 175 is displayed blinking to emphasize it, and the name corresponding to the symbol, such as "Tsuruma Park", is displayed in the overlap area of the screen. . That is, the seventh
As shown in the figure, the map data recorded on the CD 21 consists of a plurality of map sections (indicated by solid lines in the figure) A (α, β
) is composed of a set of In step 155, it is determined to select, for example, map section A (a, b) among the plurality of map sections A (α, β). However, the display screen area DR (
It is shown by magnetic lines in the same figure. ) is the determined map section A(a,
b) Wider and adjacent 8 map sections A (a-1
, b+1), A (a, b+1), A (a+
1°b+1), A(a-1,b), A(a+1.b).

A (a-1, b-1), A (a, b-1),
A (a+1.b-1) and each boundary region OR (indicated by diagonal lines in the figure) is included. This boundary area OR is called an overlap area of the screen. Therefore, step 155
Map section A (a, b) determined in
(step 165), the display screen includes map section A (a, b) and boundary area OR, as shown in the figure. Further, the location of the target facility (for example, the location of a park) is indicated by the symbol [○] (step 170).
, the symbol PI closest to the center of the screen (the highlighted symbol [○] in the figure) is displayed blinking, and the name of the target facility (in this example, "Tsuruma Park") is displayed in the above-mentioned operating lamp area. displayed (step 180).
Next, the process proceeds to step 185, where various switch and key signals are read.

In the following step 190, it is determined whether the signal read in step 185 corresponds to a cursor key operation, and if an affirmative determination is made, steps (195, 205, 215) are performed.
, 225), if a negative determination is made, the process proceeds to step 235, respectively.

When the cursor key 110 that instructs movement in the "up" direction is operated, the process proceeds to step (195, 200), and when the cursor key 11R that instructs movement in the "right" direction is operated, the process proceeds to step (205, 210). When the cursor key 11D that instructs movement in the "down" direction is operated, step (
215, 220), when the cursor key 11L instructing movement in the "left" direction is operated, steps (225, 220) are operated.
30) respectively. Each of these processes flashes another symbol determined by the cursor key operation in place of the symbol currently flashing on the display screen, and is a process that follows the same logical procedure. Therefore, the steps (205, 210
) will be explained based on FIG. 8 as an example. As shown in the figure, the horizontal position on the screen of the currently blinking symbol P1 is the coordinate Xc(k), and the vertical position on the screen is the coordinate Yc(k). If the cursor key signal input in step 185 is "right", the shortest distance is within an included angle of 45 degrees (indicated by a broken line in the figure) in the horizontal direction to the right of symbol P1. Symbols at a distance (
In this case, symbol P2) is replaced with symbol P1,
Next, it will be displayed blinking. In order to realize this feature, first, in step 205, the horizontal and vertical coordinates [Xc (k), Yc (k
)ko, horizontal and vertical coordinates of other symbols [Xn(k)
.

Yn(k)], and a process is performed to search for symbols included in the range within the included angle 45['1 in the right ice horizontal direction, according to the condition of the following equation (1).

Xn (k)-Xc (k) ≧IYn(k)-Yc(k)l-(1) Then, as shown in FIG. 8, symbols P2. P3°P4 is searched. Next, the process proceeds to step 210, where processing is performed to select the symbol with the minimum horizontal distance (Xn-Xc) from the symbol P1 currently blinking from among the symbol group searched in step 205. . In this case, the minimum horizontal distance x
Symbol P2 at position 1 is selected. Thereafter, the process returns to step 180, and instead of symbol P1, symbol P2 is flashed and displayed, and the name of the target facility indicated by symbol P2 is displayed in the overlap area. Therefore, as shown in FIG. 8, for example, when changing the blinking display from the initially blinking symbol P1 to symbol P4, the following operation is performed. First, "right"
Operate the cursor key 11R to instruct direction movement to select the horizontal and vertical coordinates [Xc (k)] that are currently blinking.

From symbol P1 of Yc(k)], horizontal and vertical coordinates [X
n (k), Yn (k)], the blinking display is changed to symbol P2. Next, operate the cursor key 11R to instruct movement in the "right" direction again to move from the symbol P2 of the horizontal and vertical coordinates [Xc (k+1), Yc (k+1)] currently blinking to the horizontal and vertical coordinates [ Xn (k+1),
The blinking display is changed to symbol P3 of [Yn (k+1)]. Furthermore, when the cursor key 110 instructing movement in the "up" direction is operated, the horizontal and vertical coordinates [Xn( 1<+2).

The blinking display is changed to symbol P4 of [Yn (k+2)]. By repeating cursor key operations like this,
After the symbol targeted by the operator is displayed blinking (steps 180 to 230), if it is determined in step 190 that the signal read by step 185 does not correspond to cursor key operation, the process proceeds to step 235. move on. In step 235, it is determined whether or not the signal read in step 185 is a set signal caused by the operation of the set switch 14. If an affirmative determination is made, the process proceeds to step 240.
On the other hand, if the determination is negative, the process proceeds to step 250.

In step 240, which is executed in response to the operation of the center switch 14, a control signal for searching and reading detailed information of the symbol currently blinking is transmitted to the stored information reproduction 83.
! Processing is performed to output the data to at least one of the compact disc player 22, digital audio recorder 24, and IC card reader/writer 26 of No. 3. Next, the process proceeds to step 245, in which a control signal for displaying the detailed information retrieved in step 240 on the screen is output to the display 4, and then the process proceeds to step 250. Through the process of step 245, detailed information related to the symbol is displayed on the display 4, for example, as shown in FIG. In the following step 250, step 18
It is determined whether the signal read in step 5 is a return signal caused by the operation of the return switch 15, and if it is affirmative, it is assumed that the return switch 15 has been operated.
On the other hand, if the determination is negative, it is determined that it is still necessary to continue displaying the detailed information, and the process returns to step 185. Thereafter, the information display process repeats steps 100 to 250 at predetermined time intervals.

Note that in this embodiment, the stored information reproducing device 3 and the CD 2
1 corresponds to the map information storage means M1, the display 4 corresponds to the display means M2, and the operation section 2 corresponds to the operation means M3.

Also, among the ECU3 and the processes executed by the ECU3,
Steps (130-175) serve as display control means M4, steps (180-230) serve as search means M5,
Each functions. Furthermore, the stored information reproducing device 3, the CD 21, the digital audio tape 23, and the IC card 25 correspond to the related information record/1 means M6, and the ECU 3 and the EC
The processing steps (235 to 245) executed by U3 function as selection display means M7.

As explained above, according to this embodiment, the display 4
The location of the target facility can be displayed as a superimposed symbol on the map displayed on the screen, and at first the symbol near the center of the display screen can be displayed blinking, and then the symbol according to the operator's will can be displayed blinking. Instead of a map, detailed information on target facilities desired by the driver or passengers can be displayed.

In addition, when the operator selects the display information hierarchy by operating the switches and keys on the operation unit 2 based on the menu screen, the user can search among the three levels of high, middle, and low levels based on the criteria according to the operator's wishes. Multiple symbols can be displayed on the map, and detailed information on the symbol selected by the operator using the cursor keys can be displayed. A highly functional automobile information display device can be provided.

This has a very significant effect when the driver operates it while the vehicle is running.

In other words, if you do not wish to display detailed information or target facilities, the device functions as a navigation device that displays a normal map, improving the efficiency of using the device.

Also, as the stored information reproducing device 3, a compact disc player 22, a digital audio tape recorder 24
, an IC card reader/writer 26 is used, a CD 21 is used as a map storage medium, and a digital audio tape 23 and an IC card 25 are used as detailed information storage media, so if the vehicle is equipped with an energized in-vehicle audio system, By adding a program that performs information display processing, the device can be modified relatively easily, increasing the versatility of the device.

In addition, a CD exclusively for reading out relatively universal map information.
Since the detailed information that changes relatively frequently is recorded in the digital audio chip 23 and the IC card 25, it is particularly easy to update the detailed information.

In this embodiment, the CD 21 is used as a map storage medium, and the digital audio tape 23 is used as a detailed information storage medium.
Although an IC card 25 is used, for example, if map information and detailed information are both recorded on the CD 21, the device configuration of the stored information reproducing device 3 can be simplified.

Further, in this embodiment, the display map is configured to be determined in response to a switch operation of the operation unit 2 by the operator. However, for example, it may be configured to be automatically determined according to the current position of the vehicle transmitted from the navigation computer 7.

Although the embodiments of the present invention have been described above, the present invention is not equally limited to these embodiments, and it goes without saying that it can be implemented in various forms without departing from the gist of the present invention. .

Effects of the Invention As described in detail above, the in-vehicle information display device of the present invention is capable of displaying information from a display target group that is limited according to a restriction command and whose geographical position is superimposed on map information, according to a target command. The searched specific display target is displayed so as to be distinguishable from other display targets, and when the specific display target corresponds to the final target target, detailed related information of the final target target is displayed. . Therefore, the position of the target facility can be displayed superimposed on the displayed map, and detailed information of the target facility can be displayed instead of the map, which is an excellent effect.

This effect is particularly remarkable, as it is possible to provide sufficient information regarding the target facility to the driver or passenger of the vehicle while driving through a geographically unfamiliar place.

In addition, when the operator selects the type and hierarchy of information related to the target facility, information can be displayed according to the operator's intention, making it possible to provide information that meets the operator's requirements.
The operability and functionality of the device will also be improved.
