When a residual quantity of a battery of a self-propelled cleaner is decreased, automatic cleaning is interrupted and driving of a cleaner mechanism is simultaneously stopped, and when a forward obstacle is detected while allowing a self-propelled cleaner to be traveled along a wall, a rotary encoder measures a traveling distance of a cleaner body BD, thereby measuring a depth of the obstacle. Then, in a case where the measured traveling distance (X) is equal to a width (H) of a charger device that projects from the wall, it is judged that the obstacle is the charger device, and traveling of the self-propelled cleaner is controlled in such a manner that its charging terminal is operatively connected to an electrical supply terminal of the charger device. Thus said charging-type travel system is precisely self-traveled to a charger device and cause itself be positively subjected to charging.

A travel direction designating unit designates a travel direction of a travel lane where a subject vehicle travels, by using an image of a paint photographed by an in-vehicle camera. On the other hand, a travel direction extracting unit extracts a travel direction in which the subject vehicle should travel in line with a route to a destination from the current position of the subject vehicle. Further, a determining unit determines whether the extracted travel direction in line with the route matches with the designated travel direction. It is thereby determined whether the subject vehicle travels towards a proper road.

Devices, methods, and programs correct an estimated path found by dead reckoning navigation. A point correlation value s is calculated based on a distance to a reliability circle whose radius is a speculative maximum error e that indicates a distance of an error range with respect to a GPS position. A correlation value Sp of an estimated path and a correlation value Sq of a candidate path are calculated from cumulative values of the point correlation values s. A correction that moves the estimated path is not performed if the correlation value Sq of the candidate path becomes worse than the correlation value Sp of the estimated path, and the correction of the estimated path is performed if the correlation value Sq of the candidate path does not become worse than the correlation value Sp of the estimated path. Thus, false matching can be further reduced, and the travel path can be suitably corrected.

A navigation apparatus and a map matching method are provided which enable correct determination that a vehicle is traveling a downgrade or an upgrade link. Information on gradients of road links is incorporated and stored in a map database. An acceleration sensor detects an acceleration of the vehicle. A gradient determination section determines an angle of inclination θ of the road link being currently traveled or a value corresponding to the angle θ (sin θ) using the acceleration detected by the acceleration sensor. The gradient determination section determines a vertical distance traveled from the inclination angle and from a speed of the vehicle to accumulate the distances, each serving as a vertical deviation. If the accumulated value of the vertical deviations H is larger than a set value TH, the determination section determines that the road link being traveled is the upgrade or downgrade link. A map matching processor performs map matching processing using a result of the determination and the gradient information.
