Abstract

An information terminal includes: an operation assignment information storage unit that stores operation assignment information; an actuation information reception unit that receives from an in-car device actuation information; an assignment unit that, on the basis of the operation assignment information and the actuation information, assigns some among a plurality of operations in the information terminal to each of one or more actuations among a plurality of types of actuation that can be inputted with an actuation unit provided to the in-car device respectively, according to priority levels; an actuation signal reception unit that receives an actuation signal outputted from the in-car device; and a conversion unit that, on the basis of the result of assignment by the assignment unit, converts the actuation signal into an operating command that corresponds to one among the plurality of operations.

First claim

The invention claimed is:

1. An in-car information system comprising an in-car device and an information terminal that is capable to be connected to the in-car device, wherein:
the in-car device includes:
an in-car device display monitor of a touch panel type;
an in-car device interface unit that transmits actuation information on the basis of actuation on the in-car device display monitor; and
a video signal input unit that receives a video signal transmitted from the information terminal;

the information terminal includes:
an information terminal display monitor of a touch panel type;
an information terminal interface unit that receives the actuation information;
a video signal output unit that transmits the video signal for a display on the in-car device display monitor; and
a memory unit that stores an application for in-car information systems capable to be selected and started via the actuation on the in-car device display monitor and an application manager that recognizes the application for in-car information systems selected via the actuation on the in-car device display monitor;

the in-car device becomes ready to transmit a start command for the application manager to the information terminal when the in-car device interface unit and the information terminal interface unit are mutually connected together and also the video signal input unit and the video signal output unit are mutually connected together;
the information terminal starts the application manager to transmit, from the video signal output unit to the in-car device, the video signal for displaying a menu screen on the in-car device display monitor when the information terminal receives the start command from the in-car device; and
the in-car device receives the video signal by the video signal input unit to display the menu screen on the in-car device display monitor on the basis of the received video signal.

2. An in-car device that is capable to be connected to an information terminal, comprising:
a display monitor of a touch panel type;
an interface unit that transmits actuation information on the basis of actuation on the display monitor; and
a video signal input unit that receives a video signal transmitted from the information terminal, wherein
the in-car device becomes ready to transmit a start command for an application stored in the information terminal to the information terminal when the interface unit and the video signal input unit are connected to the information terminal.

3. An in-car device according to claim 2 , wherein:
an application for in-car information systems capable to be selected and started via the actuation on the display monitor and an application manager that recognizes the application for in-car information systems selected via the actuation on the display monitor are stored in the information terminal; and
the in-car device becomes ready to transmit the start command for the application manager when the interface unit and the video signal input unit are connected to the information terminal.

4. An in-car device according to claim 3 , wherein
the in-car device displays a menu screen for selecting the application for in-car information systems on the display monitor when the application manager is started on the information terminal.

5. An in-car device according to claim 4 , wherein:
the menu screen includes an icon corresponding to the application for in-car information systems; and
the in-car device outputs a signal to start the application for in-car information systems to the information terminal when the icon is selected on the menu screen.

6. A menu screen display method for an in-car information system comprising an information terminal and an in-car device that is capable to be connected to the information terminal, wherein:
the in-car device includes:
a display monitor of a touch panel type;
an interface unit that transmits actuation information on the basis of actuation on the display monitor; and
a video signal input unit that receives a video signal transmitted from the information terminal; and
the menu screen display method comprises:
setting the in-car device to be ready to transmit a start command for an application stored in the information terminal from the in-car device to the information terminal when the interface unit and the video signal input unit are connected to the information terminal;
receiving the video signal for displaying a menu screen by the video signal input unit from the information terminal; and
displaying the menu screen on the display monitor on the basis of the received video signal.

7. A menu screen display method according to claim 6 , wherein:
an application for in-car information systems capable to be selected and started via the actuation on the display monitor and an application manager that recognizes the application for in-car information systems selected via the actuation on the display monitor are stored in the information terminal; and
the in-car device becomes ready to transmit the start command for the application manager when the interface unit and the video signal input unit are connected to the information terminal.
