摘要:
The present invention relates to an on-board navigation system which continuously informs a driver of the degree of approach of a vehicle to a destination by outputting a sound suited to the driver's actual running feeling.

A navigation system includes a device for extracting map data and location name data of different locations and their corresponding coordinate data; a position detector which detects the vechile position; a map display controller which displays map data on a display, and a calculating device for determining a straight-line distance from the vehicle position to the different locations thereby producing distance values. A location name display device displays location names on the display in ascending order based on the distance values, and a user selects a desired location from among the location names displayed. The extracting device may segregate the different locations based on different categories, and the map display controller retrieves map data around a location represented by coordinate data corresponding to the desired location selected by the user.

A navigation apparatus including a position detector for detecting an vehicle's position and outputting vehicle's position data, a memory for storing map data, a display unit for displaying a variety of information, and a display controller for displaying a map on the display unit based on the map data and superimposing the vehicle's position on the map displayed on the display unit based on the vehicle's position data. The apparatus further includes a commander for specifying an arbitrary position on the map displayed on the display unit; a coordinate calculator for calculating the latitude and longitude as the coordinates of the actual location corresponding to the specified position on the map and outputting the same as coordinate data; and a coordinate display controller for superimposing the coordinates of the actual location in numerical values on the displayed map based on the coordinate data.
摘要:
An on-board navigation apparatus in which one of a plurality of service facilities displayed on a display is designated by an operator input, the position coordinate data corresponding to the designated one service facility is registered as a user position into a memory. When the map is displayed on the display, the position coordinate data which has been user position registered is read out from the memory. The position on the map indicated by the position coordinate data is multiplexed onto the map by a predetermined pattern and displayed on the display. The positions of the service facilities such as restaurants, hotels, or the like, which are necessary for each user, consequently, can be easily confirmed on the displayed map.

An on-board navigation apparatus is designed to shorten the time for a display operation at the time of displaying a map and scrolling a screen while employing a buffer memory with a smaller memory capacity. The apparatus reads only block data of a block containing a display center point and block data of blocks adjoining thereto and stores the data into a buffer memory, and acquires display data forming a display screen with the display center point as a reference point from the buffer memory and performs a display operation. The reading/storing operation includes an operation of storing the block containing the display center point and blocks adjoining thereto separately into the buffer memory. The display control operation includes an operation of temporarily storing the display data into a display buffer memory before displaying it.

An actual running distance ab from a starting position to a present position of a vehicle is calculated based on input starting position data and positions continuously detected using a GPS device etc. An estimated running distance bc from the present position to a destination is calculated based on a detected present position and input destination data. A degree of attainment T representing a degree of approach to the destination is calculated according to an equation of: T=ab/(ab+bc), and is indicated on a display to announce it to a driver.

摘要:
A method of processing information of a recording disc among a plurality of recording discs having different standards or recording formats, includes the steps of: selecting and exchanging an objective recording disc to be reproduced among the plurality of recording discs; executing a recording information reproducing operation on the basis of an application program of the selected objective recording disc; and selecting and exchanging the objective recording disc only with respect to the recording discs, having the standard or recording format reproducible by the application program, among the plurality of recording discs after executing the recording information reproducing operation.

A navigation system is provided with: a position measuring device for measuring a current position of a movable body to which the navigation system is equipped; a storing device for storing aerial photograph data; a displaying device; and a display controlling device coupled to the position measuring device, the storing device, and the displaying device, for making the displaying device display a mark indicating the measured current position on an aerial photograph image on the basis of the measured current position and the stored aerial photograph data.
摘要:
An on-board navigation apparatus constantly displays characters of name data associated with geographical data in legible order and direction whenever the display direction is changed to one of the north, south, east, and west directions. In operation, after the geographical data and associated name data in a desired region are read, name reference point and name area of the read name data is retrieved, and display direction of map orientation is retrieved. Coordinates of a drawing start point are then calculated on the basis of absolute coordinate of name reference point in accordance with the display direction. Correspondence between absolute coordinates of the geographical data and the coordinates of the drawing start point of the name data is established, and the name data is written into the name area so that the geographical data and the name data are stored while being superimposed with each other, thereby forming map data. The display is performed on the basis of the map data produced by the superimposition.
