Abstract
Abstract In a vehicle navigation apparatus for searching for a route to a destination from a start location or present location and for providing guidance along a searched route, the apparatus is featured in that a search processing is selected from between a route search processing with respect to a peripheral or nearby area around a present vehicle location and a full-range route search processing up to the destination in accordance with the condition upon occurrence of an out-of-the-route, that the apparatus has a function of re-searching by use of the selected search processing, and that the full-range route search processing is selected under the condition that the vehicle goes straight at certain intersections to be turned for a predetermined number of times. The apparatus further provides improved recognizability by preventing the inherent or negative map display from becoming difficult to see in the case of displaying several landmarks on a guidance screen.

position and for providing guidance along the route
searched, characterized in that said apparatus has a function of performing a re-search
by a selected searching processing as selected between a
route search processing of a nearby area around the present
position and an entire route search processing covering a
fill range up to the destination in accordance with
conditions of a situation when a vehicle is out of the
guidance route, and a function of selecting the entire route search
processing to the destination when the vehicle goes straight
by passing through a predefined number of intersections to
be turned.
Claim 2
Dependent Claim
155 words
A vehicle navigation apparatus characterized by
comprising: present position detection means; out-of-the-route recognition means for recognizing
occurrence of an out-of-the-route; out-of-the-route condition judgement means for judging
a condition upon occurrence of an out-of-the-route condition
as recognized by said out-of-the-route recognition means; route search processing selection means for, when said
out-of-the-route condition judgment means recognizes
occurrence of an out-of-the-route event under certain
condition, selecting any one of a near-the-present-position
route search processing and an entire route search
processing to the destination; route search means for performing a route search in
conformity with a route search processing of the type as
selected by said route search processing selection means;
and guidance means for providing guidance along a route as
searched by said route search means, wherein said route
search processing selection means selects the entire route
search processing to the destination when a vehicle goes
straight by passing through a predetermined number of
intersections to be turned.
Claim 3
Dependent Claim
38 words
The vehicle navigation apparatus as recited in
claim 1 or 2, characterized in that the entire route search
processing to the destination is selected when the vehicle
becomes out of the route on a specific type of road.
Claim 4
Dependent Claim
35 words
The vehicle navigation apparatus as recited in
claims 1 to 3, characterized in that the entire route search
processing to the destination is selected when a predefined
number of times of out-of-the-route events occur
continuously.
Claim 5
Dependent Claim
97 words
A storage medium storing therein a built-in
program for searching for a route to a destination from a
start location or a present position and for providing
guidance along the route searched, characterized in that
said program comprises: judging a condition upon occurrence of an out-of-the-route
event; selecting, in accordance with the condition as judged
when the out-of-the-route occurred, any one of a near-the-present-position
route search processing and an entire route
search processing covering a full range up to the
destination; performing a route search by use of the selected search
processing; and outputting the route searched.
Claim 6
Dependent Claim
61 words
The storage medium as recited in claim 5,
characterized by having a built-in program comprising: judging whether a vehicle goes straight by passing
through a predefined number of intersections to be turned;
and selecting the entire route search processing to the
destination when the vehicle is judged to go straight by
passing through a predefined number of intersections to be
turned.
Claim 7
Dependent Claim
47 words
The storage medium as recited in claim 5 or 6,
characterized by having a built-in program comprising: judging a road type when the out-of-the-route occurred;
and selecting the entire route search processing to the
destination when the out-of-the-route event is occurred on a
specific type of road.
Claim 8
Dependent Claim
50 words
The storage medium as recited in claims 5 to 7,
characterized by having a built-in program comprising: judging whether a predetermined number of out-of-the-route
events take place continuously; and selecting the entire route search processing to the
destination when the predetermined number of times of out-of-the-route
events took place continuously.
