Abstract

A method of updating map address data in a navigation system by first determining when the navigation system has used a destination address number that was input by a driver to calculate the route to the destination address, then determining when an engine of a vehicle has been shut off after the navigation system was used to calculate a route to the destination address. Next, the navigation system determines whether the vehicle is within a predetermined range from the map address stored in a memory of the navigation system. If so, the navigation system learns the address that is the closest to the location where the vehicle was shut off and the navigation system adjusts the map address in memory based on the address that is closest to the location where the vehicle was shut off.

Claims

1. A method of updating a map address of map address data in a navigation system, the method comprising:

determining when the navigation system used a destination address number input by a driver to calculate a route to a destination address;

determining when an engine of a vehicle has been shut off after the navigation system was used to calculate a route to the destination address;

determining whether the vehicle is within a predetermined range from the map address that is stored in a memory of the navigation system;

learning the address that is the closest to the location where the vehicle was shut off; and

adjusting the map address in memory based on the address that is closest to the location where the vehicle was shut off.

2. The method of claim 1, wherein adjusting the map address further comprising:

adjusting the map address to become an adjusted map address based on a pair of map addresses, a first address of the pair representing a beginning address and a second address of the pair representing an ending address, the actual address located between the pair of map addresses and along a portion of a same road.

3. The method of claim 2, further comprising:

adjusting each of a plurality of address locations in memory that are between the beginning address and the adjusted map address at equally spaced intervals.

4. The system of claim 2, further comprising:

adjusting each of a plurality of address locations that are between the ending address and the adjusted map address at equally spaced intervals.

5. The method of claim 4, wherein the plurality of address locations in memory that are between the beginning address and the adjusted map address, and the plurality of address locations that are between the ending address and the adjusted map address are adjusted at equally spaced distances.

6. The method of claim 1, wherein a lower limit of the predetermined range is about 100 meters.

7. The method of claim 6, wherein an upper limit of the predetermined range is about 200 meters.

8. The method of claim 7, further comprising:

preventing the map address from being corrected when the upper limit is within the predetermined range, when the vehicle has been shut off and before arriving at the desired location.

9. A method of updating a map address and determining a route using a navigation system of a vehicle, the method comprising:

entering a driver-entered address number in the navigation system for a desired address;

calculating a route to the driver-entered address number from a map address location in navigation memory;

determining when an engine of a vehicle has been shut off after calculating a route to the driver-entered address number from a map-address location in navigation memory;

memorizing a location where the vehicle was turned off;

determining whether the vehicle is geographically within a predetermined distance range from the map address location stored in a memory of the navigation system;

learning the actual address that is closest to the location where the vehicle was turned off;

adjusting the map address in memory with a map address based on the actual address that is closest to the location where the vehicle was turned off; and

determining a destination route based on the adjusted map address.

10. The method of claim 9 wherein adjusting the map address further comprises:

adjusting the map address in memory to an adjusted map address based on a first map addresses representing a beginning address and a second map address representing an ending address, the first and second map addresses located along a portion of a road, the actual address located between the first and second map addresses.

11. The method of claim 10, further comprising:

adjusting a location of each of a plurality of address locations in the map data that are between the beginning address and the adjusted map address at equal intervals.

12. The method of claim 10, further comprising:

adjusting a location of each of a plurality of address locations that are between the ending address and the adjusted map address at equal intervals.

13. The method of claim 9, wherein the predetermined distance range includes from 100 meters up to and including 200 meters.

14. The method of claim 9, wherein an upper limit of the predetermined distance range is 200 meters.

15. The method of claim 14, further comprising:

preventing the navigation system from correcting the map address when the vehicle has been shut off before arriving at the desired location and the vehicle is farther than the upper limit from the map address location stored in a memory of the navigation system.

16. A method of updating map address data in a navigation system of a vehicle, the method comprising:

entering an address number using a driver interface of the navigation system;

calculating a route to a desired address that correlates to the address number;

shutting off an engine of the vehicle after calculating a route to the desired address;

determining whether the vehicle is within a predetermined range of distance from a location corresponding to the map address stored in a memory of the navigation system;

learning an actual address nearest to the location where the vehicle was shut off;

adjusting the map address in memory using an adjusted map address using the actual address where the vehicle was shut off and a first road end address and a second road end address of a road along which the actual address is located; and

determining a destination route based on the adjusted map address.

17. The method of claim 16, further comprising:

adjusting a location of each of a plurality of addresses in the map address that are between the first road end address and the adjusted map address to equal intervals.

18. The method of claim 17, further comprising:

adjusting the location of each of a plurality of addresses in the map address that are between the second road end address and the adjusted map address to equal intervals.

19. The method of claim 16, wherein:

a lower limit of the predetermined range of distance is 100 meters; and

an upper limit of the predetermined range of distance is 200 meters.
