    • Routes from a departure area to a plurality of destination areas are found as a departure-area route network data set and a plurality of such departure-area route network data sets computed for all departure areas are then stored in advance in a road-map storing memory unit 4 and a departure-area route network data storing memory unit 5. At a route-search time, a departure-area determining unit 3 determines the departure area of the vehicle to which a departure position pertains and a route-search processing means 7 uses a departure-area route network data set for the departure area determined by the departure-area determining unit 3 as well as road maps of the departure area and the vicinity of a departure position to search for guidance routes from the departure position to the destination position in a short time, presenting the guidance routes to the driver.

    • An on-vehicle information processing unit includes a central processing unit; a first device connected to the central processing unit; a device-dependent driver for driving only the first device; an operating-system-standard (OS-standard) driver enabling an application to drive devices different from the first device; a device-dependent application using the first device through the device-dependent driver; and an OS-dependent application for using the first device through the OS-standard driver. The central processing unit can include a switch for enabling the OS-dependent application only when using an Internet function, and for operating the device-dependent application in a normal mode.

    • A navigation device includes a platform having hardware including at least a user operation unit and a map database, and basic functions to control the hardware. The navigation device also includes an application processing unit for providing navigation services using the basic functions of the platform, and a platform-dependent unit for, when transferring information from the platform to the application processing unit, transferring the information in a constant format, and for, when transferring information from the application processing unit to the platform, transferring it in a certain format which depends on the platform. The map database holds map data in a predetermined recording format. The navigation device can further include a map-database-dependent unit for receiving map data, which is read from the map database by the platform-dependent unit, and for supplying the received map data to the application processing unit in the constant format. The navigation device can also include a user-interface-dependent unit for receiving data corresponding to a user's operation, which is read from the user operation unit by the platform-dependent unit, and for supplying the received data to the application processing unit in the constant format.
    • 导航装置包括具有至少包括用户操作单元和地图数据库的硬件的平台以及用于控制硬件的基本功能。 导航装置还包括使用平台的基本功能提供导航服务的应用处理单元,以及平台相关单元,用于当从平台向应用处理单元传送信息时,以恒定格式传送信息,以及 因为当将信息从应用处理单元传送到平台时,以一定的格式将其传送到依赖于该平台的位置。 地图数据库以预定的记录格式保存地图数据。 导航装置还可以包括用于接收地图数据的地图数据库相关单元,该地图数据是由依赖于平台的单元从地图数据库读取的,并且以接收的地图数据以恒定格式提供给应用处理单元。 导航装置还可以包括:用户接口依赖单元,用于接收与用户操作相对应的数据,该用户操作由平台相关单元从用户操作单元读取,并且用于将接收到的数据提供给应用处理单元 常数格式。
