Abstract
Abstract A position input system for a vehicular navigation apparatus includes an input unit (1) for inputting a desired destination and a present position, a memory unit (4) for storing desired destination information and map information, and a display unit (3) for outputting the desired destination information and map information in response to input information from the input unit (1). The map information is indicative of intersections and a geographical point located between intersections and possessing useful guidance information. A desired destination and present position are capable of being inputted by setting the useful guidance information between a road leading to and a road leading from the geographical point. This makes it possible to enter position simply and accurately. Positions are precise since they are selected from pre-stored information relating to geographical locations. Vehicle direction can also be inputted in accurate fashion where parking lot exits and intersections are concerned.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A position input system for a vehicular navigation apparatus in which guidance information for travel to a desired destination by an automotive vehicle is outputted when said desired destination is inputted, comprising: input means for inputting a desired destination and a present position; memory means for storing desired destination information and map information; and display means for outputting said desired destination information and said map information in response to the input information from said input means; said map information being indicative of intersections and a geographical point located between intersections and possessing useful guidance information, wherein desired destination and present position are capable of being inputted by setting said useful guidance information between a road leading to and a road leading from said geographical point.
Claim 2
Dependent Claim
125 words
A position input system for a vehicular navigation apparatus in which guidance information for travel to a desired destination by an automotive vehicle is outputted when said desired destination is inputted, comprising: input means for inputting a desired destination and a present position; memory means for storing desired destination information and map information; and display means for outputting said desired destination information and said map information in response to the input information from said input means; said map information being indicative of intersections and a geographical point located between intersections and possessing useful guidance information, wherein desired destination and present position are capable of being inputted by setting said useful guidance information between a road leading to and a road leading from said geographical point.
Claim 3
Dependent Claim
15 words
The system according to claim 1, wherein said desired destination information is parking lot information.
Claim 4
Dependent Claim
20 words
The system according to claim 1, wherein said desired destination information is inputted according to genre or by code number.
Claim 5
Dependent Claim
17 words
The system according to claim 1, wherein present position is inputted by code number or by character.
Claim 6
Dependent Claim
36 words
The system according to claim 4, wherein an intersection is displayed and an input is made by referring to said effective guidance information between the road leading to and the road leading from said geographical point.

Dependent Claim
19 words
The system according to claim 1, wherein the desired destination information and map information is stored in a CD-ROM.
Claim 8
Dependent Claim
143 words
A position input system for a vehicular navigation apparatus in which coordinates of a plurality of geographical points are set and in which guidance information for travel to a desired destination by an automotive vehicle is outputted at each of the geographical points when the desired destination is inputted, comprising: input means for inputting a desired destination and a present position; memory means for storing desired destination information and map information; and display means for outputting said desired destination information and said map information in response to the input information from said input means; said map information being indicative of intersections and a geographical point located between intersections and possessing useful guidance information, wherein desired destination and present position are capable of being inputted by setting said useful guidance information between a road leading to and a road leading from said geographical point.
Claim 9
Dependent Claim
143 words
A position input system for a vehicular navigation apparatus in which coordinates of a plurality of geographical points are set and in which guidance information for travel to a desired destination by an automotive vehicle is outputted at each of the geographical points when the desired destination is inputted, comprising: input means for inputting a desired destination and a present position; memory means for storing desired destination information and map information; and display means for outputting said desired destination information and said map information in response to the input information from said input means; said map information being indicative of intersections and a geographical point located between intersections and possessing useful guidance information, wherein desired destination and present position are capable of being inputted by setting said useful guidance information between a road leading to and a road leading from said geographical point.
