Vehicle navigation system having position correcting function and position correcting method
First Claim
Patent Images
1. A vehicle navigation system comprising:
- a position determination unit for generating original position data indicating an original position of a vehicle;
a memory device storing map data;
a map matching means for matching a current position of the vehicle to a road on a map utilizing the map data of the memory device; and
a voice recognition means for recognizing a voice input, wherein the map matching means initially sets the original position specified by the position determining unit as the current position of the vehicle on the map, wherein the map matching means sets an input position specified by the voice input as the current position of the vehicle on the map, after setting the original position as the current position, when the voice input specifying the input position is inputted by a user and recognized by the voice recognition means, and wherein the voice input identifies the input position relative to the original position.

Abstract
A vehicle navigation system includes a map matching module and a voice recognition module. When the voice recognition module recognizes a user'"'"'s voice input specifying an exit of a parking garage, the map matching module sets a current position of a vehicle to the specified position on a map. When the voice recognition module recognizes “high,” which indicates a elevated road, the current position is set onto the elevated road on the map. Likewise, the current position is set to a specific position on the map when the voice recognition module recognizes a user'"'"'s voice input specifying a correct current position.

5. A current position correcting method for a vehicle navigation system having a map matching module and a voice recognition module comprising steps of:
-
determining an original position of a vehicle on a map based on original position data received from a position determination unit;
receiving a voice input specifying an input position of a vehicle to the voice recognition module, after the step of determining an original position;
recognizing the received input position;
sending the voice input to the map matching module; and
setting the input position specified by the voice input as a current position of the vehicle on a map, wherein the voice input identifies the input position relative to the original position. - View Dependent Claims (6, 7, 17)

10. A position correcting method for a vehicle navigation system, comprising:
-
determining an original position of the vehicle on the map based on original position data received from a position determination unit;
receiving a voice input including voice position information for a vehicle, after the step of determining an original position;
recognizing the received voice position information; and
setting a new position of a vehicle on a map based on the received voice position information, wherein the voice position information identifies the new position relative to the original position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 19)
