Abstract

PURPOSE:To make it easy to see the mark of the position of a vehicle by providing a control portion with both an indicating portion which does not display desired layer information and a monocolor display indicating portion, and further simplifying display. CONSTITUTION:During normal operation, map information and the position of a vehicle on the map are displayed as marks on a display portion 5 and the mark of the position of the vehicle on the map is moved as the vehicle moves, and the map displayed is also moved as needed. The map is displayed using map information stored on a CDROM disc 1 while color order by the disc 1 is totally followed. If the mark of the position of the vehicle is difficult to see, the order of preventing indication of predetermined layer information is given to a control portion 3 and then only that layer information is eliminated so that the mark of the vehicle position can be easily seen. When the map information is displayed in a single color the mark of the vehicle position is easier to see and also the kind of data can be easily discriminated by the process of making only the display color of another information, e.g. a character layer different from those of the other information.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an in-vehicle navigation device that displays the location of the vehicle on a map and informs the driver of the vehicle.

(Prior art and problems to be solved by the invention) An in-vehicle navigation device is a C
Equipped with a DROM disk and a vehicle position sensor that uses a gyro compass or an artificial satellite, etc., as the vehicle moves, a map including the vehicle position is displayed on a CRT-like display by checking playback data from the CDROM and vehicle position. By checking the location of the vehicle on the map, the driver can determine the destination or the route to the destination.

By the way, in the above-mentioned in-vehicle navigation system, the CD
In addition to the map information on the ROM disk, that is, road information, background information such as buildings and bridges, and character information explaining roads and backgrounds,
Various information (tourist information, parking lot information, etc.) within the display area may be displayed (Japanese Patent Laid-Open No. 1-288719), and each information is displayed in a color-coded manner. For example, in road information, national roads are color coded in red, prefectural roads in green, and other roads in blue, yellow, etc. For this reason, when all information is displayed on a display, it becomes extremely difficult to see if the vehicle position mark overlaps a crowded area of the road or text. In addition, with conventional devices, information other than map information can be displayed or selected by instructions from the operation panel, but the original information on the map cannot be erased, so it is possible to reduce the text information or It was necessary to take measures such as devising the location of information etc.

Therefore, the present invention makes it possible to simplify the display and make the own vehicle position mark easier to see.

(Means for Solving the Problems) An in-vehicle navigation device according to the present invention includes a CDROM disk storing various information, an own vehicle position sensor, an operation section for giving display instructions, and a predetermined information based on memory information and own vehicle position information. In devices equipped with a control processing section that performs display output and a display section that performs a predetermined display, the area information data format of the CDROM disk is divided into a character symbol layer, a background layer, and a road layer and stored in the memory, and the operation section The present invention is characterized in that the control processing section is provided with an instruction section not to display desired layer information, and the control processing section is provided with a function of not outputting the predetermined layer information in response to the instruction.

In addition, in the above-mentioned in-vehicle navigation device equipped with the CDROM disk, the own vehicle position sensor, the operation section, and the control processing section, the color data based on the drawn color parameters stored in the CDROM disk can be operated without being directly displayed. The present invention is characterized in that a one-color display instruction section is provided in the section, and the control processing section has a processing function for processing the output of a predetermined color parameter in one color in response to the instruction.

(Function) When displaying a map and the vehicle's position on the map on a display such as an in-vehicle CRT, normally all map information such as roads, backgrounds, and text are displayed in predetermined colors. , the map display also changes as the vehicle progresses. Especially in map information,
When you want to exclude text display or background display, the display is excluded layer by layer, and other layer information is superimposed on the program and output and displayed as map information. Also, when displaying map information, the display color is set to one color and output.

(Example) Next, examples of the present invention will be described.

The present invention includes a CD ROM disk 1, an own vehicle position sensor 2,
It is composed of an operation section 3, a control processing section 4, and a display section 5. The CDROM disk 1 stores map information of a predetermined area, drawing color parameters for determining the display color of the map information, and other management programs. To explain in more detail, the map information consists of a road layer a1 that stores only the relative positions of roads; a background layer b1 that stores the road background such as buildings, bridges, rivers, and oceans; and a background layer b1 that stores characters and symbols that describe roads and backgrounds. It is divided into character and symbol layers C, and color classifications are also stored so that each piece of memory information can be displayed in a predetermined color. The own vehicle position sensor 2 detects the moving direction and displacement of the vehicle using a gyro compass, an artificial satellite, or the like. The operation section 3 is made up of a group of predetermined switches, receives display instructions from the operator (driver), and includes at least an instruction section for selection and removal of the layers and an instruction section for color unification in addition to a normal display instruction section. It becomes.

The control processing section 4 includes a CDROM disk playback device 41 and a processing section (CF4 etc.) 42, and receives memory information of the CDR'OM disk 1 from the playback device, information from the own vehicle position sensor 2, and an operation section 3. It receives instruction information from and outputs a predetermined display, and is particularly equipped with a function of not outputting predetermined layer information and a function of outputting color classification in one color. The display section 5 is composed of a CRT display device or a liquid crystal display device, and receives the display output from the control processing section 4 and displays a predetermined display.

To explain the operation of the in-vehicle navigation device, normally, map information and the vehicle's position on the map are displayed on the display unit 5 as a mark, and the vehicle's position mark on the map moves as the vehicle travels. Furthermore, the displayed map also moves as appropriate. This map displays all the map information stored in the CD-ROM disk 1 in accordance with the color instructions.

In particular, when the vehicle position mark is difficult to see, certain layer information is not displayed. For example, road layer information is displayed as shown in Figure 3 (B), or road layer information is displayed as shown in Figure 3 (B).
As shown in (c) of the same figure, information on the character symbol layer is not displayed, or as shown in (c) of the same figure, information on the background layer is not displayed. Therefore, the own vehicle position mark becomes easier to see. Furthermore, if the map information is displayed in one color, it will be easier to see the own vehicle position mark, and
By processing other information, such as making only the display color of the character layer a different color from other display colors, it becomes easier to distinguish between data types.

In the present invention, it goes without saying that tourist spot information, parking lot information, etc. other than map information can be stored in the CDROM disk 1 and displayed on the display unit 5 as needed.

(Effects of the Invention) The present invention provides an in-vehicle navigation device with a CDRO
When displaying the map information stored in the M disk on the display, each layer or color information stored in the divided memory is erased in the program so that the information is not displayed, making the display more visible. Moreover, even if the map information is detailed, it has the advantage of eliminating visual inconveniences by erasing part of it.
