Abstract
A navigation system for use in a subject vehicle for organizing a navigation instruction of a navigation route toward a destination in map data includes a closeness determination function for determining that a current position of the subject vehicle from the destination is a predetermined range, and a partial route audio navigation provision function for collectively providing the navigation instruction in an audible manner from the current position of the subject vehicle to the destination based on determination by the closeness determination function.
Claims12
A navigation system for use in a subject vehicle for organizing a navigation instruction of a navigation route toward a destination in map data comprising:
- a closeness determination means for determining that a current position of the subject vehicle from the destination is within a predetermined range;
- and
- a partial route audio navigation provision means for collectively providing the navigation instruction in an audible manner from the current position of the subject vehicle to the destination based on determination by the closeness determination means.
A navigation system comprising:
- a navigation route evaluation means for determining a navigation route having a lower audio navigation cost in comparison with a plurality of the navigation routes toward a destination, wherein the audio navigation cost represents evaluation of difficulty of provision of navigation instructions in an audible manner;
- and
- a navigation instruction provision means for providing the navigation instructions for the navigation route determined by the navigation route evaluation means.
A navigation system comprising:
- a facility search means for searching a facility within a predetermined range of a destination of a navigation route by using facility data having position attribute and landmark index, wherein the landmark index represents evaluation of distinction of the facility as a landmark;
- and
- a navigation instruction means for providing navigation instructions with reference to the facility searched by the facility search means, the facility having higher landmark index relative to other facilities based on the facility data.
A computer program for a navigation system comprising a computer usable medium having computer program logic recorded thereon for enabling generation of a control program in a computer, the computer program logic comprising:
- a closeness determination procedure for determining that a current position of the subject vehicle from the destination is a predetermined range;
- and
- an audio navigation provision procedure for collectively providing the navigation instruction in an audible manner from the current position to the destination based on determination by the closeness determination procedure.
A program for a navigation system comprising a computer usable medium having computer program logic recorded thereon for enabling generation of a control program in a computer, the computer program logic comprising:
- a navigation route evaluation procedure for determining a navigation route having a lower audio navigation cost in comparison with a plurality of the navigation routes toward a destination, wherein the audio navigation cost represents evaluation of difficulty of provision of navigation instructions in an audible manner;
- and
- a navigation instruction provision procedure for providing the navigation instructions for the navigation route determined by the navigation route evaluation procedure.
A program for a navigation system comprising a computer usable medium having computer program logic recorded thereon for enabling generation of a control program in a computer, the computer program logic comprising:
- a facility search procedure for searching a facility within a predetermined range of a destination of a navigation route by using facility data having position attribute and landmark index, wherein the landmark index represents evaluation of distinction of the facility as a landmark;
- and
- a navigation instruction procedure for providing navigation instructions with reference to the facility searched by the facility search procedure, the facility having higher landmark index relative to other facilities based on the facility data.
