TRAVEL GUIDING APPARATUS FOR VEHICLE, TRAVEL GUIDING METHOD FOR VEHICLE, AND COMPUTER-READABLE STORAGE MEDIUM
First Claim
1. A travel guiding apparatus for a vehicle, comprising:
- a storage unit that stores map information and marker pattern identification information used to identify a marker pattern for each road type, wherein the marker pattern is a pattern of a marker included in a lane marking;
a first road type determination unit that determines a type of a vehicle traveling road on which a vehicle is traveling, based on a current position of the vehicle and the map information;
a marker pattern detection unit that detects the maker pattern on the vehicle traveling road;
a second road type determination unit that determines the type of the vehicle traveling road, based on the marker pattern detected by the marker pattern detection unit and the marker pattern identification information; and
a road type change unit that changes the type of the vehicle traveling road determined by the first road type determination unit from a road other than an expressway to an expressway, if the first road type determination unit determines that the type of the vehicle traveling road is a road other than an expressway, and the second road type determination unit determines that the type of the vehicle traveling road is an expressway.

Abstract
A travel guiding apparatus, method, and program for a vehicle store map information and marker pattern identification information used to identify a marker pattern for each road type, wherein the marker pattern is a pattern of a marker included in a lane marking. The apparatus, method, and program determine a type of road on which the vehicle is traveling and detect the maker pattern on the road. The apparatus, method, and program again determine the type of the road based on the detected marker pattern and change the type of determined road from a road other than an expressway to an expressway, if the first detected type of road is a road other than an expressway and the type of road detected based on the marker pattern is an expressway.

6. A travel guiding method for a vehicle, comprising:
-
performing a first road type determination that determines a type of a vehicle traveling road on which a vehicle is traveling, based on a current position of the vehicle and map information stored in a storage unit; detecting a maker pattern that is a pattern of a marker included in a lane marking on the vehicle traveling road; performing a second road type determination that determines the type of the vehicle traveling road, based on the detected marker pattern and marker pattern identification information stored in the storage unit, wherein the marker pattern identification information is used to identify the marker pattern for each road type; and changing the type of the vehicle traveling road determined by the first road type determination from a road other than an expressway to an expressway, if it is determined that the type of the vehicle traveling road is a road other than an expressway by the first road type determination, and it is determined that the type of the vehicle traveling road is an expressway by the second road type determination.

7. A computer-readable storage medium that stores computer-executable instructions for performing a travel guiding method for a vehicle comprising:
-
performing a first road type determination that determines a type of a vehicle traveling road on which a vehicle is traveling, based on a current position of the vehicle and map information stored in a storage unit; detecting a maker pattern that is a pattern of a marker included in a lane marking on the vehicle traveling road; performing a second road type determination that determines the type of the vehicle traveling road, based on the detected marker pattern and marker pattern identification information stored in the storage unit, wherein the marker pattern identification information is used to identify the marker pattern for each road type; and changing the type of the vehicle traveling road determined by the first road type determination from a road other than an expressway to an expressway, if it is determined that the type of the vehicle traveling road is a road other than an expressway by the first road type determination, and it is determined that the type of the vehicle traveling road is an expressway by the second road type determination.
