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 non-transitory memory that stores;
map information; and
marker pattern identification information used to identify a marker pattern for each road type, the marker pattern identification information indicating a pattern of a marker included in a lane marking; and
a controller that;
makes a first determination of a road type of a road on which the vehicle is traveling based on a current position of the vehicle and the stored map information;
detects the maker pattern on the traveled road;
makes a second determination of the road type of the traveled road based on the detected marker pattern and the stored marker pattern identification information;
changes the first determined road type from a road other than an expressway to an expressway when the first determined road type is a road other than an expressway, and the second determined road type is an expressway; and
does not change the first determined road type from a road other than an expressway to an expressway based on the second determined road type when the first determined road type 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:
-
accessing a memory storing; map information; and marker pattern identification information used to identify a marker pattern for each road type, the marker pattern identification information indicating a pattern of a marker included in a lane marking; performing, with a controller, a first road type determination of a road type of a road on which the vehicle is traveling based on a current position of the vehicle and the accessed map information; detecting, with the controller, the maker pattern on the traveled road; performing, with the controller, a second determination of the road type of the traveled road based on the detected marker pattern and the accessed marker pattern identification information; changing, with the controller, the first determined road type from a road other than an expressway to an expressway when the first determined road type is a road other than an expressway and the second determined road type is an expressway; and not changing the first determined road type from a road other than an expressway to an expressway based on the second determined road type when the first determined road type is an expressway.

7. A non-transitory computer readable storage device that stores computer-executable instructions for performing a travel guiding method for a vehicle comprising:
-
accessing a memory storing; map information; and marker pattern identification information used to identify a marker pattern for each road type, the marker pattern identification information indicating a pattern of a marker included in a lane marking; performing, with a controller, a first road type determination of a road type of a road on which the vehicle is traveling based on a current position of the vehicle and the accessed map information; detecting, with the controller, the maker pattern on the traveled road; performing, with the controller, a second determination of the road type of the traveled road based on the detected marker pattern and the accessed marker pattern identification information; changing, with the controller, the first determined road type from a road other than an expressway to an expressway when the first determined road type is a road other than an expressway and the second determined road type is an expressway; and not changing the first determined road type from a road other than an expressway to an expressway based on the second determined road type when the first determined road type is an expressway.
