Abstract

An onboard information system has multiple onboard apparatuses and an external communication unit 6 connected to an in-vehicle LAN 7, and multiple mobile devices 8 connected to the external communication unit via communication. A mobile device transmits a communication request to the external communication unit which transmits an ID assigned to the request-originating mobile device and an initial operation picture to the request-originating mobile device. The request-originating mobile device transmits an onboard apparatus selected in the initial operation picture and the ID to the external communication unit which transmits, when the ID is valid, an apparatus operation picture to the request-originating mobile device. The request-originating mobile device transmits a command selected in the apparatus operation picture to the onboard apparatus which transmits a processing result corresponding to the command to the request-originating mobile device via the external communication unit. The request-originating mobile device outputs the processing result.

Claims

1. An onboard information system comprising:

an onboard apparatus connected to a LAN; and

an external communication unit which is connected to the LAN for carrying out communication with the outside, and which enables a mobile device to access the onboard apparatus,

wherein

the external communication unit assigns an ID to the mobile device in response to a communication request received from the mobile device, and transmits the assigned ID and an initial operation picture including an icon representing the onboard apparatus to the mobile device;

the external communication unit, which receives apparatus information and the ID transmitted from the mobile device, transmits, when the ID received is valid, an apparatus operation picture which enables selection of a command for operating the onboard apparatus designated by the apparatus information received from the mobile device to the mobile device;

the external communication unit, which receives the command to the onboard apparatus transmitted from the mobile device, transmits the command to the onboard apparatus;

the onboard apparatus, which receives the command from the external communication unit, executes processing corresponding to the command and transmits a processing result to the external communication unit; and

the external communication unit transmits the processing result received from the onboard apparatus to the mobile device.

2. The onboard information system according to claim 1, wherein

the external communication unit, which receives the apparatus information and the ID transmitted from the mobile device, transmits, when the received ID is valid and when the onboard apparatus designated by the apparatus information operates in response to a communication request from another mobile device, information that the mobile device is not given priority;

and gives, when the received ID is valid and when the onboard apparatus designated by the apparatus information does not operate in response to a communication request from another mobile device, a priority to the mobile device, and transmits to the mobile device an apparatus operation picture including commands for operating the onboard apparatus designated by the apparatus information received from the mobile device.

3. The onboard information system according to claim 2, wherein

the external communication unit, which receives the apparatus information and the ID transmitted from the mobile device, transmits, when transmitting a processing result received from the onboard apparatus designated by the apparatus information to the another mobile device having a priority, the processing result transmitted to the another mobile device to the mobile device.

4. The onboard information system according to claim 3, wherein

the external communication unit, which receives the priority request, the apparatus information and the ID transmitted from the mobile device, gives a priority to the mobile device when the received ID is valid and when the onboard apparatus designated by the apparatus information is controllable, and transmits to the mobile device an apparatus operation picture including commands for operating the onboard apparatus designated by the apparatus information.

5. An external communication unit of an onboard information system, which is connected to a LAN to which an onboard apparatus is connected, for carrying out communication with the outside and for enabling a mobile device to access the onboard apparatus, wherein the external communication unit of the onboard information system:

assigns an ID to the mobile device in response to a communication request received from the mobile device, and transmits the assigned ID and an initial operation picture including an icon representing the onboard apparatus to the mobile device;

receives the apparatus information and the ID transmitted from the mobile device, and transmits, when the received ID is valid, an apparatus operation picture which enables selection of a command for operating the onboard apparatus designated by the apparatus information received from the mobile device to the mobile device;

transmits the command to the onboard apparatus when receiving the command transmitted from the mobile device to the onboard apparatus; and

transmits a processing result of processing corresponding to the command received from the onboard apparatus to the mobile device.

6. The external communication unit of an onboard information system according to claim 5, wherein

the external communication unit, which receives the apparatus information and the ID transmitted from the mobile device, transmits when the received ID is valid and when the onboard apparatus designated by the apparatus information operates in response to a communication request from another mobile device, information that the mobile device is not given a priority;

and gives, when the received ID is valid and when the onboard apparatus designated by the apparatus information does not operate in response to a communication request from another mobile device, a priority to the mobile device, and transmits to the mobile device the apparatus operation picture including commands for operating the onboard apparatus designated by the apparatus information received from the mobile device.

7. The external communication unit of an onboard information system according to claim 6, wherein

the external communication unit, which receives the apparatus information and the ID transmitted from the mobile device, transmits, when transmitting a processing result received from the onboard apparatus designated by the apparatus information to the another mobile device having a priority, the processing result transmitted to the another mobile device to the mobile device.

8. The external communication unit of an onboard information system according to claim 7, wherein

the external communication unit, which receives the priority request, the apparatus information and the ID transmitted from the mobile device, gives a priority to the mobile device when the ID received is valid and when the onboard apparatus designated by the apparatus information is controllable, and transmits to the mobile device an apparatus operation picture including commands for operating the onboard apparatus designated by the apparatus information.
