Navigation device and method for selectively displaying thoroughfare names
DCFirst Claim
1. A navigation device for navigating a vehicle on a thoroughfare, said device comprising:
- a memory containing cartographic data indicative of a plurality of thoroughfares, including said thoroughfare upon which said vehicle is being navigated, wherein at least one of said thoroughfares intersects said thoroughfare upon which said vehicle is being navigated, and wherein each of said thoroughfares has an associated name stored in memory;
a processor connected to said memory; and
a display, connected to said processor, for displaying said cartographic data, wherein said display displays the name of each of said thoroughfares that intersects with said thoroughfare upon which said vehicle is being navigated, but does not display the name associated with said thoroughfare upon which said vehicle is being navigated.

Abstract
A navigation device for selectively displaying thoroughfare names utilizes a processor, memory, display, input and antenna/receiver. The navigation device, incorporated within a vehicle receives GPS satellite signals from a plurality of satellites orbiting the earth and calculates its position, velocity and direction. Cartographic data, including data indicative of thoroughfares and their corresponding names is stored in the memory and displayed on the display along with an icon indicative of the location of the vehicle. As the vehicle is navigated along a thoroughfare displayed on the display, the processor causes the display to display the names of thoroughfares which, in one embodiment, intersect with the thoroughfare being navigated; in another embodiment are crosswise with the thoroughfare being navigated. Preferably, only the names of thoroughfares which intersect or are oriented crosswise with the thoroughfare being navigated within a selected angle from perpendicular to the thoroughfare being navigated are displayed. The invention thus displays the thoroughfare names that are most likely of interest without cluttering the display.

12. A method of displaying navigation data on the display of a navigation device, for navigating a thoroughfare, said device having a memory containing data indicative of a plurality of thoroughfares, including said thoroughfare being navigated, and wherein a first plurality of said thoroughfares intersect with the thoroughfare being navigated, and a second plurality of said thoroughfares do not intersect with the thoroughfare being navigated, and wherein each said thoroughfare has an associated name stored in said memory, the method comprising:
-
displaying images representative of said thoroughfare;
selecting, based upon a direction in which said navigation device is being navigated, a plurality of said thoroughfares; and
displaying the names of each said thoroughfare in said selected plurality of thoroughfares. - View Dependent Claims (13, 14)
