Navigation apparatus for a vehicle
First Claim
Patent Images
1. A navigation apparatus for a vehicle, comprising:
- information storage means for storing information regarding roads and intersections;
present position detecting means for detecting the present position of the vehicle;
destination setting means for setting a destination;
enroute point setting means for setting enroute points to be passed through;
route calculating means for calculating a route to the destination set by said destination setting means based on the information stored in said information storage means and the enroute points set by said enroute point setting means;
route storage means for storing the route calculated by said route calculating means; and
route guidance means for providing route guidance based on the route calculated by said route calculating means and the present position detected by said present position detecting means, wherein said route storage means stores each section of the route between enroute points, said route calculating means that performs partial route recalculation for each section between the enroute points on demand and enables a user to modify the entire route by individually retrieving and editing each stored section between the enroute points and route guidance is determined and edited individually for each section defined by a plurality of the enroute points set between a start point and the destination, such that when a user changes the original calculated route, the enroute point before the section to be edited is designated as “
ROUTE START POINT” and
the enroute point after the section to be edited is designated as “
ROUTE END POINT”
, and only the edited section of the entire route is recalculated in determining the modified route.

Abstract
In a navigation apparatus for a vehicle, an entire route from a start point to a destination is determined and the vehicle is guided to the destination in accordance with the determined route. In the navigation apparatus, an entire route from a start point to a destination is first determined. Route determination is performed for a part of the entire route in accordance with a request of a user, and the entire route to the destination is determined again based on the result of the determination performed for the part of the entire route. The navigation apparatus has a first remaining-distance displaying unit and a second remaining-distance displaying unit. The first remaining distance display unit displays an arrow indicating the route and the remaining distance to an intersection. The second remaining-distance display unit deletes the display of the distance provided by the first remaining-distance display unit and changes the length of the arrow, which indicates the route, as the vehicle advances.

2. A navigation apparatus for a vehicle, comprising:
-
information storage means for storing information regarding roads and intersections;
present position detecting means for detecting the present position of the vehicle;
destination setting means for setting a destination;
enroute point setting means for setting enroute points to be passed through;
route calculating means for calculating a route for each section between the present position of the vehicle detected by said present position detecting means, based on information stored in said information storage means, the enroute point set by said enroute point setting means, and the destination set by said destination setting means;
route storage means for storing each section of the route calculated by said route calculating means; and
route change directing means for directing a change in the route for each of said sections, wherein said route calculation means is provided with route recalculation means that performs partial route recalculation for each stored section that is designated by a user to be changed, and route editing means for editing the entire route from the present position of the vehicle to the destination by individual retrieving and editing each section between enroute points, said route storage means stores the route edited by said route editing means and is provided with route guidance means for providing route guidance based on the route stored in said route storage means and the present position of the vehicle detected by said present position detecting means, and route guidance is determined and edited individually for each section defined by a plurality of the enroute points set between a start point and the destination, such that when a user changes the original calculated route, the enroute point before the section to be edited is designated as “
ROUTE START POINT” and
the enroute point after the section to be edited is designated as “

3. A navigation apparatus for a vehicle in which an entire route from a start point to a destination is determined and the vehicle is guided to the destination in accordance with the determined route, said navigation apparatus comprising:
-
means for setting a plurality of enroute points located between the start point and the destination so that sections are defined among the start point, the enroute points, and the destination;
means for setting different conditions for each section;
means for determining a route segment for each section based on the conditions set for the section;
means for storing each section of the route determined by said determining means;
means for determining the entire route to the destination by individually retrieving and editing each stored section between enroute points; and
means for individually selecting and editing the sections and the route segments by a user, such that when a user changes the original calculated route, the enroute point before the section to be edited is designated as “
ROUTE START POINT” and
the enroute point after the section to be edited is designated as “
ROUTE EIND POINT”
, and only the route in the edited section of the entire route is recalculated in determining a modified route.
