Abstract

In a navigation apparatus, an acquiring unit acquires traveling state information indicating a traveling state of a mobile object. A position identifying unit identifies a current position of the mobile object based on the traveling state information and map information. The destination setting unit sets a destination. A route searching unit searches for a route based on the destination. A route guidance unit performs route guidance based on the route. A parking determining unit determines whether the mobile object is parked. If during the route guidance, the current position of the mobile object identified to be on a road within a first predetermined range from the destination is identified not to be on any road and it is determined that the mobile object is parked, a registering unit registers the most recent deviation point as an entrance point of a parking lot of the destination into a storage unit.

Claims

1-9. -9. (canceled)

10. A navigation apparatus comprising:

an acquiring unit that acquires traveling state information indicating a traveling state of a mobile object;

a position identifying unit that identifies a current position of the mobile object based on the traveling state information and map information;

a destination setting unit that sets a destination;

a route searching unit that searches for a route based on the destination;

a route guidance unit that performs route guidance based on the route;

a parking determining unit that determines whether the mobile object is parked; and

a registering unit that registers into a storage unit, a deviation point from a road as an entrance point of a parking lot of the destination when the mobile object is determined to be parked after the mobile object is identified to be on a road within a first predetermined range from the destination and is subsequently identified not to be on any road, wherein

the registering unit, for one destination, registers into the storage unit, only a most recent deviation point as the entrance point of the parking lot of the one destination while the route guidance is in progress.

11. The navigation apparatus according to claim 10, wherein the registering unit, while the route guidance is in progress, erases the entrance point of the parking lot of the destination registered in the storage unit during the route guidance if the mobile object is determined to be parked when the mobile object is identified to be on a road within a second predetermined range smaller than the first predetermined range from the destination.

12. The navigation apparatus according to claim 10, wherein the registering unit, while the route guidance is in progress, if the current position of the mobile object identified not to be on any road is subsequently identified to be on a road after the entrance point of the parking lot of the destination is registered, registers into the storage unit, a returning point onto the road as an exit point of the parking lot of the destination and registers only a most recent returning point for the one destination as the exit point of the parking lot of the one destination.

13. The navigation apparatus according to claim 12, wherein the registering unit, while the route guidance is in progress, if the mobile object is determined to be parked when the mobile object is identified to be on a road within a second predetermined range smaller than the first predetermined range from the destination, erases the entrance point and the exit point of the parking lot of the destination registered in the storage unit during the route guidance.

14. A navigation apparatus comprising:

an acquiring unit that acquires traveling state information indicating a traveling state of a mobile object;

a position identifying unit that identifies a current position of the mobile object based on the traveling state information and map information;

a destination setting unit that sets a destination;

a route searching unit that searches for a route based on the destination;

a route guidance unit that performs route guidance based on the route;

a parking determining unit that determines whether the mobile object is parked; and

a registering unit that registers into a storage unit, a deviation point from a road as an entrance point of a parking lot of the destination when the mobile object is determined to be parked after the mobile object is identified to be on a road within a first predetermined range from the destination and is subsequently identified not to be on any road, wherein

the registering unit, while the route guidance is in progress, erases the entrance point of the parking lot of the destination registered in the storage unit during the route guidance if the mobile object is determined to be parked when the mobile object is identified to be on a road within a second predetermined range smaller than the first predetermined range from the destination.

15. A position registering method of a navigation apparatus including a destination setting unit, a route searching unit that searches for a route based on a destination, and a route guidance unit that performs route guidance based on the route, the position registering method comprising:

an acquiring step of acquiring traveling state information indicating a traveling state of a mobile object;

a position identifying step of identifying a current position of the mobile object based on the traveling state information and map information;

a saving step of temporarily saving a deviation point from a road when the mobile object identified to be on the road is subsequently identified not to be on any road;

a parking determining step of determining whether the mobile object is parked when the mobile object is identified not to be on any road; and

a registering step of registering the deviation point as an entrance point to a parking lot of the destination when the deviation point is within a predetermined range from the destination and the mobile object is determined to be parked, wherein

the registering step includes, for one destination, registering into the storage unit, only a most recent deviation point as the entrance point of the parking lot of the one destination while the route guidance is in progress.

16. A position registering method of a navigation apparatus including a destination setting unit, a route searching unit that searches for a route based on a destination, and a route guidance unit that performs route guidance based on the route, the position registering method comprising:

an acquiring step of acquiring traveling state information indicating a traveling state of a mobile object;

a position identifying step of identifying a current position of the mobile object based on the traveling state information and map information;

a saving step of temporarily saving a deviation point from a road when the mobile object identified to be on the road is subsequently identified not to be on any road;

a parking determining step of determining whether the mobile object is parked when the mobile object is identified not to be on any road; and

a registering step of registering the deviation point as an entrance point to a parking lot of the destination when the deviation point is within a first predetermined range from the destination and the mobile object is determined to be parked, wherein

the registering step includes, while the route guidance is in progress, erasing the entrance point registered in the storage unit during the route guidance if the mobile object is determined to be parked when the mobile object is identified to be on a road within a second predetermined range smaller than the first predetermined range from the destination.

17. A computer-readable recording medium storing therein a position-registering computer program that causes a computer to execute:

an acquiring step of acquiring traveling state information indicating a traveling state of a mobile object;

a position identifying step of identifying a current position of the mobile object based on the traveling state information and map information;

a saving step of temporarily saving a deviation point from a road when the mobile object identified to be on the road is subsequently identified not to be on any road;

a parking determining step of determining whether the mobile object is parked when the mobile object is identified not to be on any road; and

a registering step of registering the deviation point as an entrance point to a parking lot of the destination when the deviation point is within a predetermined range from the destination and the mobile object is determined to be parked, wherein

the registering step includes, for one destination, registering into the storage unit, only a most recent deviation point as the entrance point of the parking lot of the one destination while the route guidance is in progress.
