Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an in-vehicle navigator that allows map information to be easily viewed even when the amount of information on one display device is increased.

(Conventional technology) FIG. 5 shows the configuration of a conventional in-vehicle navigator.

In FIG. 5, a sensor 1 provides information for determining the position of the vehicle to the arithmetic control means 3. 2 is an input means, and the driver uses this input means to perform various operations such as initial settings and map searches. 4 is an auxiliary storage means having map information, and the map information includes text information such as place names and road names, and non-text information such as roads and railways.

5 is a display means for informing the driver of the map information read out from the auxiliary storage means 4 and the running state of the vehicle.

Next, the operation of the conventional example will be explained. In FIG. 5, first, the driver uses the input means to select and decide which character information to display. Then, when the vehicle runs, the sensor 1 operates and sends data to the calculation control means 3. In the calculation control means 3, the position calculation means 3-1 operates first to calculate the current position of the vehicle. Next, the map position calculating means 3-2 reads out the map representing the current position of the vehicle from the auxiliary storage means 4, and calculates points corresponding to the current position on the map. The display control means 3-3 displays the driving state of the vehicle on the display means 5 together with map information such as text information and non-text information to inform the driver.

(Problems to be Solved by the Invention) However, in the conventional in-vehicle navigator described above, all of the text information included in the map information is displayed in the same area as non-text information such as roads, When the density of map data is high and the amount of text information is large, not only does the screen become complex, but there are also problems in that it becomes difficult to distinguish non-text information from the text information.

Additionally, when using a display device with low resolution, there is a limit to the number of characters that can be displayed, and therefore, there is also a limit to the amount of character information in the map data, making it difficult for drivers to obtain detailed data. was there.

The present invention has been made to solve these conventional problems, and it is an object of the present invention to provide an excellent in-vehicle navigator whose display device is easy to see and can display a detailed map.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an input means for inputting one of two character information selections for map search, and a sensor for obtaining information for determining the position of a vehicle. and auxiliary storage means having map information consisting of text information and non-text information;
a position calculating means for calculating the current position of the vehicle from data from the sensor; and a map host for reading out from the auxiliary storage means a map on which the vehicle position obtained by the above calculation is located, and calculating the current corresponding point of the vehicle position on the map. 'F!
1 arithmetic means, display character information selection means for reading information determined by the input means from the auxiliary storage means, selecting only character information from the map information, and sending a signal for marking the position of the character information on the map; , a calculation means comprising display control means for displaying the selected character information in the character display area of the display means and map information, vehicle running information and the markings in other areas; The display device also includes a display means having a character display area.

(Function) The present invention has the following effects due to the above configuration.

That is, since the display means is provided with a character display area, the nine-character information does not interfere with other non-character information, so that the display device can be easily viewed. Furthermore, in the present invention, single-character information can be selectively displayed even when using a low-resolution display means, so the amount (density) of character information in map information is not limited. The display device can be made easier to see.

(Embodiment) FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, a sensor 1 provides information for determining the position of the vehicle to the arithmetic control means 3. 2 is an input means, and the driver uses this input means to perform various operations such as initial settings and map searches. 4 is an auxiliary storage means having map information, and the map information includes text information such as place names and road names, and non-text information such as roads and railways. Reference numeral 5 denotes a display means for informing the driver of the map information read from the auxiliary storage means and the running condition of the vehicle.

Next, the operation of the above embodiment will be explained. In the above embodiment, when the vehicle runs, the sensor 1 operates and sends data to the arithmetic control means 38. In the calculation control means 3,
First, the position calculation means 3-1 operates to calculate the current position of the vehicle. Next, the map position calculating means 3-2 reads the map on which the vehicle's current position is located from the auxiliary storage means 4, and calculates points corresponding to the vehicle's current position on the map. Subsequently, the display character information selection means 3-3 operates. The operation flow of the display character information selection means 3-3 is as follows.
As shown in the figure. First, conditions for which character information is to be selected and displayed are confirmed. This is input by the driver using manual means 2 if necessary. When there is no input, a point near the current position of the vehicle is selected. Next, display character information selection means 3-
3 is the map information read out from the auxiliary storage means 4,
Select only text information. Then, it selects the text that meets the "conditions for displaying text information" obtained earlier, and moves the remaining text information to the location on the map where the text information is located in order to notify the driver that text information exists. An example of the structure of the six map information to be marked is shown in FIG. The display control means 3-4 displays the selected character information in the character display area of the display means 5, and also displays non-text information such as roads and railways, driving conditions such as the speed of the vehicle, and character information in other areas. Display a mark at the location.

FIG. 4 is an example of the display on the display means when a touch panel is used as the input means. ◎ is the vehicle's current position mark, and 'X''' is a mark indicating a point with text information. In the 6 examples, the text display area has 4
Four character information can be displayed, and four points near the current position of the vehicle are selected and displayed. When the driver wants to use other text information, he or she can use the touch panel to enter the location of the text information that he or she wants to know, input display conditions, and display the information.

(Effects of the Invention) As is clear from the above embodiments, the present invention is capable of selecting only necessary text information from text information and displaying it in a text display area separate from the area where roads etc. are displayed. According to
Since there is no limit to the density of text information in map information, it is possible to have sufficient text information even in urban areas, and moreover, the map can be displayed in an easy-to-understand manner.

Furthermore, by providing a character display area on the display device, the present invention allows even when using a low-resolution display means to have the same amount of character information as when using a high-resolution display means. The cost of the device can be reduced.

Furthermore, since the present invention can display map information and text information separately, the displayed map can be simplified, a lot of map information can be shared, and text information and non-text information can be easily viewed on a display device. Can be done.
