Abstract
Abstract A traffic navigation apparatus installed on a vehicle has a record of map data of maps which covers at least the moving range of the vehicle. The apparatus detects the current vehicle position. The user sets places to be by-passed and the destination on a displayed map. The apparatus seeks a recommendable route which connects the current position and the destination by by-passing the specified avoidance places. The apparatus permits the avoidance regions to be input by various data inputs including by inputting the telephone number or a postal zip code of the region to be avoided. It then displays a recommendable route on the map which avoids the avoidance region provided the increase of distance as compared to not avoiding the avoidance region is not more than a specified value. Otherwise it displays a recommended route which includes the avoidance region in relation with the current vehicle position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A traffic navigation apparatus for a vehicle comprising: means for storing map data of a map which covers at least a moving range of said vehicle; means for detecting the current position of said vehicle; means for setting an avoidance region on said map to be by-passed by said vehicle; means for specifying two arbitrary points on said map; first search means for seeking a recommendable route between said two points; second search means for seeking a recommendable route which connects said two points by by-passing said avoidance region; and means for displaying the recommendable route which is sought by said first search means together with said map based on the current position if a difference between a distance of the recommendable route sought by said first search means and a distance of the recommendable route sought by said second search means is larger than a predetermined value, and otherwise displaying the recommendable route which is sought by said second search means together with said map based on the current position.
Claim 2
Dependent Claim
171 words
A traffic navigation apparatus for a vehicle comprising: means for storing map data of a map which covers at least a moving range of said vehicle; means for detecting the current position of said vehicle; means for setting an avoidance region on said map to be by-passed by said vehicle; means for specifying two arbitrary points on said map; first search means for seeking a recommendable route between said two points; second search means for seeking a recommendable route which connects said two points by by-passing said avoidance region; and means for displaying the recommendable route which is sought by said first search means together with said map based on the current position if a difference between a distance of the recommendable route sought by said first search means and a distance of the recommendable route sought by said second search means is larger than a predetermined value, and otherwise displaying the recommendable route which is sought by said second search means together with said map based on the current position.
Claim 3
Dependent Claim
18 words
A traffic navigation apparatus according to claim 1, wherein said avoidance region is set using a telephone number.
Claim 4
Dependent Claim
19 words
A traffic navigation apparatus according to claim 1 wherein said avoidance region is set using a postal zip code.
Claim 5
Dependent Claim
125 words
A traffic navigation method for a vehicle comprising: storing map data of a map which covers at least a moving range of said vehicle; detecting a current position of said vehicle; setting an avoidance region on said map to be by-passed by said vehicle; specifying two arbitrary points on said map and determining a recommendable route between said two points; determining a recommendable route between said two points by by-passing said avoidance region; and displaying the recommendable route, together with said map, based on the current position if the increase in distance between the recommendable route by by-passing the avoidance region and the recommendable route is larger than a predetermined value, and otherwise displaying the recommendable route by-passing the avoidance region, together with said map.
Claim 6
Dependent Claim
125 words
A traffic navigation method for a vehicle comprising: storing map data of a map which covers at least a moving range of said vehicle; detecting a current position of said vehicle; setting an avoidance region on said map to be by-passed by said vehicle; specifying two arbitrary points on said map and determining a recommendable route between said two points; determining a recommendable route between said two points by by-passing said avoidance region; and displaying the recommendable route, together with said map, based on the current position if the increase in distance between the recommendable route by by-passing the avoidance region and the recommendable route is larger than a predetermined value, and otherwise displaying the recommendable route by-passing the avoidance region, together with said map.
