Abstract
Abstract A navigation system for a vehicle enables an operator to know a calculated optimal path from a starting point to a destination before departure. After the optimal path is calculated, a preview function allows the operator to sequentially view the calculated optimal path either prior to departure or at any point along the optimal path. A cancel function allows the operator to cancel a displayed portion of the optimal path and to request calculation and display of an alternate optimal path which does not employ the canceled portion of the original optimal path.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A navigation system for a vehicle comprising: optimum path calculating means for calculating an optimal path between a starting point and a destination in accordance with a map information; present position calculating means for calculating a present position of the vehicle; path information output means for transmitting a path information based on the optimal path calculated by said optimum path calculating means from the present position of the vehicle calculated by said present position calculating means; path information display means for displaying the path information transmitted from said path information output means; and instruction signal output means having a manually-operating portion, said instruction signal output means including means for transmitting an instruction signal responsive to said manually-operating portion; and means in said path information output means for selecting and transmitting said path information.
Claim 2
Dependent Claim
133 words
A navigation system for a vehicle comprising: optimum path calculating means for calculating an optimal path between a starting point and a destination in accordance with a map information; present position calculating means for calculating a present position of the vehicle; path information output means for transmitting a path information based on the optimal path calculated by said optimum path calculating means from the present position of the vehicle calculated by said present position calculating means; path information display means for displaying the path information transmitted from said path information output means; and instruction signal output means having a manually-operating portion, said instruction signal output means including means for transmitting an instruction signal responsive to said manually-operating portion; and means in said path information output means for selecting and transmitting said path information.
Claim 3
Dependent Claim
36 words
A navigation system for a vehicle according to claim 1, wherein said path information comprises at least a turn icon, a road name, and a distance, said turn icon consisting of a microprocessor-generated videographical directional indicator.
Claim 4
Independent Claim
98 words
A method of navigating a vehicle, which comprises the steps of: calculating, on an electronically-stored map, an optimal path between a starting point and a destination; calculating on said map a present position of said vehicle; transmitting a plurality of instructions for following said optimal path from said present position to said destination; said transmitting being responsive to a request by an operator for performing said transmitting prior to traveling on said optimal path; displaying said plurality of instructions sequentially; and calculating and selecting an alternate optimal path responsive to a request from said operator of said vehicle.
Claim 5
Independent Claim
98 words
A method of navigating a vehicle, which comprises the steps of: calculating, on an electronically-stored map, an optimal path between a starting point and a destination; calculating on said map a present position of said vehicle; transmitting a plurality of instructions for following said optimal path from said present position to said destination; said transmitting being responsive to a request by an operator for performing said transmitting prior to traveling on said optimal path; displaying said plurality of instructions sequentially; and calculating and selecting an alternate optimal path responsive to a request from said operator of said vehicle.
Claim 6
Dependent Claim
105 words
A navigation system for a vehicle comprising: a microcomputer adapted for calculating, on a map available to said microcomputer, an optimal path between a starting point and a destination; sensors for determining, in cooperation with said microcomputer, a present position of said vehicle; said microcomputer being further adapted for computing a plurality of instructions for following said optimal path from said present position to said destination; means for displaying and plurality of instructions sequentially; means for enabling an operator of said vehicle to preview said optimal path; and input means for permitting said operator of said vehicle to request an alternate optimal path on demand.
Claim 7
Dependent Claim
105 words
A navigation system for a vehicle comprising: a microcomputer adapted for calculating, on a map available to said microcomputer, an optimal path between a starting point and a destination; sensors for determining, in cooperation with said microcomputer, a present position of said vehicle; said microcomputer being further adapted for computing a plurality of instructions for following said optimal path from said present position to said destination; means for displaying and plurality of instructions sequentially; means for enabling an operator of said vehicle to preview said optimal path; and input means for permitting said operator of said vehicle to request an alternate optimal path on demand.
Claim 8
Dependent Claim
15 words
A navigation system as in claim 4, wherein said input means for permitting is voice-activated.
Claim 9
Dependent Claim
35 words
A navigation system for a vehicle according to claim 4, wherein said instructions comprise at least a turn icon, a road name, and a distance, said turn icon consisting of a microprocessor-generated videographical directional indicator.
