A vehicular navigation system includes a display screen mounted on a vehicle, a run/stop detector for detecting whether the vehicle is running or stopped, a display color controller for changing the colors of the individual picture elements of the displayed picture in accordance with whether the vehicle is running or stopped; an input device for inputting the selection of and instructions for the picture; a picture transition controller for controlling the transition of the picture in accordance with the input instructions and a picture drawing processor for drawing the picture, which is controlled by the picture transition controller, in the colors of the picture elements dictated by the display color controller. The colors of the pictured elements on the display are selectively chosen in accordance with either a detected stop or detected running. A daytime/nighttime decider distinguishes between daytime and nighttime. The display color controller includes a plurality of pallets adapted to be changed in accordance with the detection of either stop or running to control the colors of the individual picture elements of the picture of the display.

A navigation system includes input means (1a) for entering a telephone number; an information storage device (3) for storing telephone-number data (3a), in which a location name inclusive of a set of coordinate is stored for each telephone number, address data (3b) in which an address is stored for each set of coordinates, and map data (3c); a central processor (4) having telephone-number retrieval means (4a) for retrieving, from the information storage device, location coordinates and location name of a telephone number entered by the input means, and address-data retrieval means (4b) for retrieving address data corresponding to the location coordinates of the telephone number entered by the input means; and display means (1b) for displaying a location name and address, which have been retrieved by the central processor, as well as a map centered on the location. Designation and entry of a location are performed by displaying the location name and address retrieved by entry of a telephone number, as well as the map centered on said location, on the display means. Since the amount of data is broken up into the telephone-number data and address data, the amount of telephone-number data can be reduced.

In order to provide a driver with guidance for a direction of travel without confusing the driver even in a case where the angular difference between an approach road and a departing road at a branch point is very small or even when a branch point has a complicated shape, a navigation system is provided with present-position sensor for calculating present position of the vehicle; an input for entering information necessary for calculating a route; an output for giving notification of information for carrying out route guidance; an information storage device in which all data necessary to carry out route guidance has been stored; route calculator for calculating a route based upon the information entered by the input; route storage for temporarily storing the route calculated by the route calculator; and a guidance control unit for outputting guidance information relating to the route to the output. The information storage device stores branch-point data and road data connected to branch points and has direction data indicative of a departing road with respect to an approach road connected thereto by a branch point. The guidance control unit outputs the guidance information to the output based upon the direction data.

A vehicle navigation system includes a present position detector, an input device for inputting information required for route searching, inclusive of information identifying a starting point and a destination, an output device for outputting route guidance, an information memory containing map data for route guidance within a geographical area, and border line data for a border line defining a perimeter for the geographical area. A central processing unit determines whether or not the detected present position or starting point and the destination are within the geographical area stored in the information memory, determines a crossing point on the border line responsive to a determination that the present position or the starting point and the destination are not both in the geographical area and determines a travel route from the present position or starting point to the destination, which travel route passes through the crossing point. The information memory may be an element additionally containing data identifying locations outside of the geographical area in the form of remote location data which is correlated with respective border points. This system allows the user to be guided to a proper border crossing point even when the destination is outside of the geographical area covered by the map data stored in the information memory element, e.g. a CD-ROM.
摘要:
A navigation system includes a first information storage device containing stored map data and a display unit for displaying a map by reading the map data. Provision is made for setting a point on the map displayed by the display unit and for inputting a telephone number. A second information storage device is provided for registering the input telephone number in correlation with the positional coordinates of the set point.

Navigation devices, methods, and programs set a destination, find an on-street parking zone that is in the vicinity of the destination, and find a route, by modifying a search cost for a road, that will arrive at the destination by way of a road having the on-street parking zone. The devices, methods, and programs acquire parking information that pertains to the on-street parking zone and find the route by modifying the search cost based on the parking information. The devices, methods, and programs find the route when the vehicle has reached a specified distance from the destination.

A vehicle guidance device is configured such that, in a case where a vehicle is parked in an on-street parking zone, the vehicle guidance device specifies a parking meter from among the parking meters for the on-street parking zone in which the vehicle is parked, then provides guidance to the position where the specified parking meter is installed. In a case where an on-street parking zone is located in the vicinity of the vehicle's current position while the vehicle is in motion, the vehicle guidance device provides guidance to the position of a parking meter for the on-street parking zone.

A vehicle navigation system is made to generate bitmap image data necessary for navigation, including map data, road data, font data, etc., and then to transmit a pattern (font) image and an enlarged intersection image to a display.
摘要:
An external storage device having navigation data and programs stored therein to perform a route search and provide route guidance, and a central processing unit which includes a program storage flash memory and program loading means for loading programs from the external storage device into the flash memory. The programs stored in the flash memory are run to perform a route search and provide route guidance. The central processing unit compares a version of each program stored in flash memory with a version of the program stored in external storage device, so that when the version of the program stored in the external storage device is more current than that stored in the flash memory, the program is loaded from the external storage device into the flash memory.
摘要:
A route guidance section compares the current position provided by a current position determination section and the route provided by a route calculation section for detecting an off-route condition. When the off-route condition is detected, a re-searching key as well as the route and current place is displayed on a display section. When the re-searching key is touched, a search is again made for a new route from the current position to the destination. Then, route guidance is again started in response to the re-searching result. When the re-searching key is not touched, the route and current place continue to be displayed while the vehicle carrying the apparatus travles off route, thereby efficiently preventing the apparatus from executing unnecessary re-searching when the driver drives the vehicle off route on purpose.
