20090024320 | Navigation apparatus - A navigation apparatus is obtained that can reduce as much as possible to blank interval during the navigation even when a route deviation has occurred. In order to structure a navigation apparatus that includes a guided vehicle position determining means | 01-22-2009 |
20090265070 | SUPPORT CONTROL DEVICE - An accuracy error for measuring the position of an own vehicle is calculated based on the information of an execution history of map matching and the information of an update history of a map database. In addition, a predetermined map is referred to based on the calculated accuracy error, and an accuracy error level for performing positioning is specified from among plural stepwise levels. Then, the control level of assist control executed according to the position of the own vehicle is changed so as to correspond to the specified accuracy error level. | 10-22-2009 |
20100061591 | OBJECT RECOGNITION DEVICE - An object recognition device detects a position of a vehicle based on a running path obtained by GPS, vehicle speed, steering angle, etc., and also detects the position of the vehicle based on a result of recognition of an object obtained using a captured image of a camera. The device computes a positioning accuracy in detecting the vehicle position, which accuracy mostly deteriorates as a movement distance of the vehicle increases. | 03-11-2010 |
20100082238 | VEHICLE POSITIONING INFORMATION UPDATE DEVICE - Based on positioning accuracy of an own vehicle required for appropriately carrying out assistance control carried out according to a position of the own vehicle, an execution condition for map matching correcting the position of the own vehicle is set. Specifically, setting is made in such a manner that, as the positioning accuracy is higher and an error thereof is smaller, an execution frequency of map matching becomes higher. Then, map matching is carried out according to the thus-set execution condition. | 04-01-2010 |
20100121886 | Map Database Generating Systems, Methods, and Programs - Systems, methods, and programs store feature information relating to features existing on a road and on the periphery of the road, each piece of feature information being associated with a unique identification symbol, each piece of feature information including disposition information expressing a spatial disposition of each feature independently of the road network, form information expressing a form of each feature, accuracy information expressing an accuracy of the information, and acquisition timing information expressing an acquisition timing of the information. The systems, methods, and programs (1) output the feature information stored in the feature database and input map information constituting the map database, the map information being generated based on the output feature information, or (2) generate map information constituting the map database on the basis of the feature information stored in the feature database. | 05-13-2010 |
20100169013 | VEHICLE POSITIONING DEVICE - Setting a planimetric feature having a high frequency of appearance as a planimetric feature to be recognized necessary for an own-vehicle position correction by referring to arrangement patterns of planimetric features having a high frequency of appearance for each of a plurality of types of road in response to a target object for an assist control, for example, a characteristic planimetric feature in an area where the own-vehicle will travel hereafter from among planimetric features on a road of which information is stored in a map database. Then, recognizing the set planimetric feature, and correcting an own-vehicle position from one based on a GPS and a travel path in accordance with a recognition result thereof. | 07-01-2010 |

20080208459 | Road-map-data configuration and navigation apparatus - A computer readable medium having stored thereon road-map-data including pieces of link information having different accuracy levels based on the accuracies of sources of the link information, whereby a computer is able to appropriately configure road-network data, on the basis of an accuracy level given in each of the pieces of link information. The road-map-data includes the road-network data representing roads as links and including connection relationships among the links, and the pieces of link information used to configure the road network data. Each piece of link information for a given link includes accuracy level information based on the accuracy of the source of that piece of link information. | 08-28-2008 |
20090216771 | MAP UPDATE SYSTEM, METHODS, AND PROGRAMS - Systems, methods, and programs store navigation map data divided into a plurality of partitions, each partition having a corresponding partition file. The systems, methods, and programs identify a partition file corresponding to a partition that is to be updated. The partition file has an update-targeted road class The systems, methods, and programs select an update file, the update file being selected from a server file corresponding to the partition file to be updated. The server file is managed by version and road class. The selected update file is selected based on the update-targeted road class. | 08-27-2009 |

20080208460 | Lane determining device, method, and program - Devices, methods, and programs obtain vehicle position information indicating a current position of a vehicle, and based on the vehicle position information, obtain road information including positions and forms of lane markings around the current position of the vehicle. Based on the road information, the devices, systems, and methods determine whether a branch point exists on the road in a forward direction of the vehicle. If a branch point exists, the devices, methods, and programs obtain image information of an area before the branch point, and determine whether no lane marking is imaged or is partly imaged in the image information of the area before the branch point. If there is no lane marking or only a partial lane marking imaged in the area before the branch point, the devices, methods, and programs obtain image information of the branch point including a captured image of a lane marking, and determine a lane in which the vehicle is traveling after the branch point based on an imaging order of the lane marking, a form of the lane marking, a position of the lane marking in the image information of the branch point, and the road information. | 08-28-2008 |
