Abstract
Abstract A map information regenerating device usable in a vehicle travel guiding apparatus, which device is capable of freely revising a road map, i.e., adding, changing and deleting a road on the road map without changing data stored in a basic map-information storage but correlating change data with existing roads to assure the possibility of performing map-data processing such as course searching according to the revised map data. The device is so constructed that the map information may be read-out from a map information storage and stored in a buffer memory wherein the data is revised in a specified procedure according to the map change data read-out from an additionally used storage medium or/and obtained by using transmitting/receiving means.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A map information regenerating device comprising: a map-information storage means for storing as road map information therein node information and link information on line segments with which roads extending on a map are approximated; a map-change information storage means for storing as road change information therein node information and link information on a road to be changed on said map, in correlation with said node information and said link information on line segments stored in said map-information storage means; a buffer memory for storing therein road map information on a specified area, said road map information being read-out from said map-information storage means; a map-information revising means for revising said road map information on said specified area stored in said buffer memory, in accordance with said road change information read-out from said map-change information storage means; and a display means for displaying on a screen a road map of said specified area in accordance with said road map information which has thus been revised.
Claim 2
Dependent Claim
164 words
A map information regenerating device comprising: a map-information storage means for storing as road map information therein node information and link information on line segments with which roads extending on a map are approximated; a map-change information storage means for storing as road change information therein node information and link information on a road to be changed on said map, in correlation with said node information and said link information on line segments stored in said map-information storage means; a buffer memory for storing therein road map information on a specified area, said road map information being read-out from said map-information storage means; a map-information revising means for revising said road map information on said specified area stored in said buffer memory, in accordance with said road change information read-out from said map-change information storage means; and a display means for displaying on a screen a road map of said specified area in accordance with said road map information which has thus been revised.
Claim 3
Dependent Claim
33 words
A map information regenerating device according to claim 1, characterized in that said map-change information storage medium includes a separate buffer memory and means for supplying map-change information to said separate buffer memory.
Claim 4
Dependent Claim
24 words
A map information regenerating device according to claim 1, characterized in that said map-change information storage medium comprises an erasable programmable read-only memory means.
Claim 5
Dependent Claim
172 words
A map information regenerating device comprising: a map-information storage means for storing as road map information therein node information and link information on line segments with which roads extending on a map are approximated; a transmitting means for transmitting, in the form of road change information, node information and link information on a road to be changed on said map, in correlation with said node information and said link information on line segments stored in said map-information storage means; a receiving means for receiving said road change information transmitted from said transmitting means; a buffer memory for storing therein road map information on a specified area, said road map information being read-out from said map-information storage means; a map-information revising means for revising said road map information on said specified area stored in said buffer memory, in accordance with said road change information received; and a display means for displaying on a screen a road map of said specified area in accordance with said road map information which has thus been revised.
Claim 6
Dependent Claim
172 words
A map information regenerating device comprising: a map-information storage means for storing as road map information therein node information and link information on line segments with which roads extending on a map are approximated; a transmitting means for transmitting, in the form of road change information, node information and link information on a road to be changed on said map, in correlation with said node information and said link information on line segments stored in said map-information storage means; a receiving means for receiving said road change information transmitted from said transmitting means; a buffer memory for storing therein road map information on a specified area, said road map information being read-out from said map-information storage means; a map-information revising means for revising said road map information on said specified area stored in said buffer memory, in accordance with said road change information received; and a display means for displaying on a screen a road map of said specified area in accordance with said road map information which has thus been revised.
Claim 7
Dependent Claim
48 words
