摘要:
When a vehicle is stationary on a slope, the vehicle is allowed to remain stably stationary without consuming much energy by controlling the attitude of a vehicle body by moving an active weight portion with no torque applied to a drive wheel by actuating a braking device to stop rotation of the drive wheel. To this end, a vehicle includes: a drive wheel rotatably attached to a vehicle body; an active weight portion attached so as to be movable relative to the vehicle body; and a vehicle control device that controls an attitude of the vehicle body by controlling at least one of a drive torque applied to the drive wheel and a position of the active weight portion. The vehicle control device controls the attitude of the vehicle body by controlling only the position of the active weight portion when the vehicle is stationary on a slope.

摘要:
A communication navigation system, wherein a navigation apparatus requests a recommended route guidance data to a information center and guides a user of the navigation apparatus to a destination by using the recommended route guidance data received from the information center. In this present invention, the navigation apparatus transmits version data of road data held in the navigation apparatus at the request to the information center. The information center prepares a guidance data of recommended route using latest road data held in the information center, and transmits the data to the navigation apparatus. When the information center transmits the guidance data, the information center selects the type of data of the road links along the recommended route, in the guidance data, by comparing the version data received from the navigation apparatus and the version data of each road link along the recommended route. If each data of road links along the recommended route is considered to be contained in the road data held in the navigation apparatus, the information center transmits the only data which enable to specify the road link from the road data held in the navigation apparatus. On the hand, if each data of road links is considered not to be contained in the road data held in the navigation apparatus, the information center transmits whole data of the road link. Therefore, the navigation apparatus can generate the route guidance data by extracting road link data, from its own road data, corresponding to the road link specified by transmitted data and by reconstructing road link data using transmitted data.

A non-contact power supply system supplies electric power in a non-contact manner from a power transmission device to a vehicle. The power transmission device includes an impedance adjusting unit configured to adjust an impedance between a power supply unit and a power transmission unit. A vehicle ECU assists an alignment between the power transmission unit and the power receiving unit in the parking operation based on a power transmission efficiency between the power transmission unit and the power receiving unit. A power transmission ECU, at the time of the alignment in the parking operation, controls the impedance adjusting unit based on a distance between the power transmission unit and the power receiving unit in a vertical direction (vehicle height). Accordingly, lowering of the power transmission efficiency caused by a change in an impedance along with a change in the vehicle height can be suppressed.

摘要:
A navigation system includes a navigation center and at least one moving body. The navigation center of the navigation system comprises memory means for storing navigation information; updating means for constantly updating the navigation information stored in the memory means; route searching means for setting a route from a current position of the moving body to a destination on the basis of the newest navigation information updated by the updating means; dividing means for dividing the searched route into at least two portions; extracting means for extracting navigation data concerning at least a head portion of the divided route from the memory means; transmitting means for transmitting to the moving body the extracted navigation data; and control means. After transmitting the navigation data for the head portion to the moving body and before transmitting navigation data for a remaining route, the control means controls each of the route searching means, the dividing means, the extracting means and the transmitting means so that each means performs the respective processes. This arrangement enables a user of the moving body to be provided with route guidance which is conducted using the navigation data formed based on the newest navigation information that reflects various road conditions.
摘要:
Disclosed is a communicatory navigation system including an information center (150), at least one navigation unit (100) each mounted on a vehicle and communication means for allowing bi-directional data communication between the information center and the navigation unit. Data transmission from the navigation unit to the information center is made during a period of communication that begins when the navigation unit become communicable with the information center and ends when the bi-directional data communication therebetween is disconnected. The navigation unit is provided with a drive route history memory area (131) and an instrument operation history memory area (132), and data in these memory areas are transmitted to the information center, together with the vehicle current position data and the destination position data. The information center determines a recommended drive route from the current position to the destination, not only with reference to its own database (158) but also taking into consideration the history data. For example, if it is determined that there is a traffic accident or heavy traffic jam in some route, a bypass route is determined and transmitted back to the navigation unit. When the previous drive route indicated by data in area (131) is not found in the database (158), it can be recognized as a newly constructed road for inclusion in the database.

A commucations navigation system in which data is transmitted and received between a navigation base apparatus provided at a navigation base and a vehicle navigation apparatus provided in a vehicle using communication. The vehicle navigation apparatus is adapted to transmit at least data concerning the current position of the vehicle and the destination thereof to the navigation base apparatus, and the navigation base apparatus stores navigation data in its data base and is adapted to determine a recommended route based on the transmitted data of the current position of the vehicle and the destination thereof and then extract data of the recommended route from the navigation data stored in the data base and transmit the extracted data to the navigation apparatus. The navigation base apparatus is adapted to be able to extract detailed navigation data only for a surrounding areas of a specified point on the recommended route from the navigation data stored in the data base and then transmit the detailed navigation data to the navigation apparatus. The specified point includes a departure point, a destination and a course-change point which are located on the recommended route. During traveling other places on the recommended route such as intermediate sections, the navigation apparatus transmits simple navigation data such as a simple map to the vehicle, thereby enabling to reduce an amount of data to be transmitted from the navigation base apparatus to the vehicle navigation apparatus.
