Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A navigation apparatus for a vehicle in which a self-supporting sensing system on the basis of a gyro, a geomagnetic sensor, a vehicle speed pulse generator and the like, and a two-dimensional sensing system or a three-dimensional sensing system on the basis of a GPS (Global Positioning System) are suitably switched to effect sensing, and information such as a present position, a running locus and the like on the basis of the sensed results are displayed in a predermined form of display on a display section, characterized in that said form of display is differentiated in response to the sensed states at the running points whether the sensed states are the self-supporting sensed state on the basis of said self-supporting sensing system, the two-dimensional sensed state on the basis of said two-dimensional sensing system or the three-dimensional sensed state on the basis of said three-dimensional sensing system.
Claim 2
Dependent Claim
44 words
A navigation apparatus according to claim 1, wherein when determination is made so that the number of artificial satellites is less than three, the form of display corresponding to the self-supporting sensed state is used to display the present position and the running locus.
Claim 3
Dependent Claim
42 words
A navigation apparatus according to claim 1, wherein when determination is made so that the number of artifical satellites is three, the form of display corresponding to the two-dimensional sensed state is used to display the present position and the running locus.
Claim 4
Dependent Claim
44 words
A navigation apparatus according to claim 1, wherein when determination is made so that the number of artificial satellites is four or more, the form of display corresponding to the three-dimensional sensed state is used to display the present position and the running locus.
Claim 5
Dependent Claim
39 words
A navigation apparatus according to claim 1, wherein the form of display for the present position is differentiated using arrows different in line and size, and the form of display for the running locus is differentiated using different colors.
Claim 6
Dependent Claim
138 words
A navigation apparatus for a vehicle comprising a display section for displaying on a display image plane information received from an operating section and information on the basis of the sensed result of a sensing section as well as a map; a foot brake actuation-state detecting section which detects an actuation state of a foot brake to thereby output an actuating output and detects a non-actuation state of the foot brake to thereby output a non-actuation signal; a timer section for counting time; and a control section in which the information is displayed on a display image plane by being supplied with the actuation signal, and when a predetermined time passes on the basis of the output from the timer section after being supplied with the actuation signal, displaying of the information on the image plane is terminated.
Claim 7
Dependent Claim
22 words
A navigation apparatus according to claim 6, wherein said navigation apparatus is controlled by a microcomputer composed of MPU, ROM and RAM.
Claim 8
Dependent Claim
14 words
A navigation apparatus according to claim 6, wherein said display section comprises a CRT.
Claim 9
Dependent Claim
23 words
A navigation apparatus according to claim 6, wherein said timer section is used in combination with a timer provided interiorly of the MPU.
