Abstract: An in-vehicle gateway apparatus includes a first communication section and a second communication section. The first communication section receives a vehicle related data set including multiple data elements from a data transmit apparatus. The second communication section transmits a processed data set processed based on the vehicle related data set to an in-vehicle LAN group including a first in-vehicle LAN and a second in-vehicle LAN. The second in-vehicle LAN has a communication speed lower than a communication speed of the first in-vehicle LAN. The second communication section transmits a first processed data set processed based on the vehicle related data set to the first in-vehicle LAN, and transmits a second processed data set processed based on the vehicle related data set and having less data elements than the first processed data set to the second in-vehicle LAN.

Abstract: A charging apparatus for an electric vehicle is provided with: a charging cable including a proximal end connected to a main body, a connector provided on a distal end, and an extra length absorbing section provided between the distal end and the proximal end; a measuring section configured to detect an elongation of the charging cable from an initial length thereof; and an electric current control section configured to start applying an electric current to the charging cable under a condition that an elongation of the charging cable exceeding a threshold value is detected by the measuring section.

Abstract: When a vehicle runs in a region other than existing roads stored as ready-made map data, learned road data is generated based on a traveling locus. Further, an existing road connected with the learned road is defined as a base link. The base link is copied and divided, to generate auxiliary link data to define a connection status between the learned road and the existing road in an auxiliary way. The learned road data and the auxiliary link data are recorded in association with each other. The auxiliary link data is used in navigation-related processing as a substitute for road data related to the existing road connected with the learned road. With this configuration, the existing road and the learned road are logically connected, to supplement consistency in a map containing the learned road without partially changing the ready-made map data.

Abstract: In adding a new road to update road map data, an amendment process is executed to remove an accumulated error included in a travel locus based on dead reckoning navigation at the time of running the new road. The new road can be thus added in updating the road map data so as to fit more with an actual shape of the new road.

Abstract: A cellular phone receives map update data from a digital broadcast provider before a start-up of a car navigation apparatus, stores the received map update data in a storage section, and transmits the map update data stored in the storage section to the car navigation apparatus in response to the start-up of the car navigation apparatus. Upon receiving the map update data, the car navigation apparatus updates map data.
