Abstract

The present invention has an object to provide a technique capable of appropriately determining whether a vehicle has entered a facility range. A navigation apparatus includes a storage, a position detector, and an entry determining unit. The storage stores map information including a facility range. The position detector detects a position of an own vehicle. The entry determining unit determines that, in a case where the position of the own vehicle detected by the position detector has entered an entry determination range associated with the facility range, the own vehicle has entered the facility range.

Claims

1-11. -11. (canceled)

12. A map information processing apparatus comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, results in performance of steps comprising,

acquiring map information including a facility range and road links, at least one of the road links being associated with said facility range,

acquiring a position of a vehicle,

acquiring one road link brought into correspondence with the position of the vehicle by comparing the position of the vehicle acquired with the road links of said map information, and

determining that, in a case where the one road link acquired is the road link associated with said facility range and the position of the vehicle acquired has entered a predetermined first range associated with said facility range, said vehicle has entered the facility range.

13. The map information processing apparatus according to claim 12, wherein

acquiring the one road link includes performing a matching processing of matching the position of the vehicle acquired with said one road link, and

the matching processing by acquiring the one road link is stopped between when it is determined that said vehicle has entered said facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range.

14. The map information processing apparatus according to claim 12, wherein

the road link associated with said facility range includes an entry road link allocated to an entry road for an entry into said facility range, and

said steps further comprise causing a notifier mounted on said vehicle to make a notification of reverse traveling in a case where the position of said vehicle has entered an overlapping range shared by said first range and a predetermined second range associated with said entry road link from a range other than said second range of said first range between when it is determined that said vehicle has entered said facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range.

15. The map information processing apparatus according to claim 14, wherein at and after the determination that said vehicle has entered said facility range in said determining, said one road link used in the determination is used as said entry road link.

16. The map information processing apparatus according to claim 12, wherein the road link associated with said facility range includes an exit road link allocated to an exit road for an exit from said facility range, and

said steps further comprise causing a notifier mounted on said vehicle to make a notification of exit traveling in a case where the position of said vehicle has entered an overlapping range shared by said first range and a predetermined third range associated with said exit road link from a range other than said third range of said first range between when it is determined that said vehicle has entered said facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range.

17. The map information processing apparatus according to claim 16, wherein at and after the determination that said vehicle has entered said facility range in said determining, a road link other than said one road link used in the determination from among the road links associated with said facility range is used as said exit road link.

18. A map information processing apparatus comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, results in performance of steps comprising,

acquiring map information including a facility range,

acquiring a position of a vehicle,

determining that, in a case where the position of the vehicle acquired has entered a predetermined first range associated with said facility range, said vehicle has entered the facility range, and

storing, between when it is determined that said vehicle has entered said facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range, a determination history of said entry,

wherein whether a current point of time is at a midpoint of a period between when it is determined that said vehicle has entered the facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range is determined based on whether the determination history of said entry is stored in said storing.

19. A method of processing map information, comprising:

specifying map information including a facility range and road links, at least one of the road links being associated with said facility range;

acquiring a position of a vehicle;

acquiring one road link brought into correspondence with the position of the vehicle by comparing the position of the vehicle acquired with the road links of said map information; and

determining that, in a case where the one road link acquired is the road link associated with said facility range and the position of the vehicle acquired has entered a predetermined first range associated with said facility range, said vehicle has entered the facility range.
