In-vehicle device, control method thereof, and remote control system

Abstract

An input/output limitation information storage unit stores input/output limitation information in which limitation processing for limiting operation input to the application and display output from the application is prescribed by associating the limitation processing with the application. A determination unit acquires a vehicle state of a vehicle, and determines the limitation processing to be applied to the operation input to the application and the display output from the application on the basis of the application running on the terminal device, the vehicle state, and the input/output limitation information. The limitation unit performs the limitation processing determined by the determination unit for the operation input detected by the input control unit and transmitted to the communication control unit, and the display output received by the communication control unit and transmitted to the output control unit.

What is claimed is: 
     
         1 . An in-vehicle device comprising:
 a telecommunication interface connectable with a terminal device which performs an application program;   a vehicle state determination unit configured to determine a state of a vehicle;   a storage unit storing input/output limitation information configured to limit display of display data received from the terminal device or limiting operation; and   a control unit configured to perform various processings,   wherein the control unit is configured to:
 control to display a result of a process that the terminal device performed the application program when the state of the vehicle determined by the vehicle state determination unit is a first state, and 
 control to display an icon of the application program being performed based on the input/output limitation information stored in the storage unit when the state of the vehicle determined by the vehicle state determination unit is a second state different from the first state. 
   
     
     
         2 . The in-vehicle device according to  claim 1 , wherein
 the control unit is configured to control to display the icon of the application program being performed based on the input/output limitation information instead of the result of the process of the application.   
     
     
         3 . The in-vehicle device according to  claim 1 , wherein
 the first state is a state that a parking brake is ON, and   the second state is a state that the parking brake is OFF.   
     
     
         4 . The in-vehicle device according to  claim 2 , wherein
 the first state is a state that a parking brake is ON, and the second state is a state that the parking brake is OFF.   
     
     
         5 . An in-vehicle device comprising:
 a telecommunication interface connectable with a terminal device which performs an application program;   a vehicle state determination unit configured to determine a state of a vehicle;   a storage unit storing input/output limitation information configured to limit display of display data received from the terminal device or limiting operation; and   a control unit performing various processings,   wherein the control unit is configured to:
 control to display a result of a process that the terminal device performed the application program when the state of the vehicle determined by the vehicle state determination unit is a first state, and 
 control to reduce a display size of the result of the process that the terminal device performed the application program to a size defined in input/output limitation information and to display the result reduced in display size. 
   
     
     
         6 . The in-vehicle device according to  claim 5 , wherein
 the first state is a state that a parking brake is ON, and the second state is a state that the parking brake is OFF.   
     
     
         7 . A controlling method for displaying, on a screen of an in-vehicle device, a result of a process performed by a terminal device connected to the in-vehicle device, wherein the method comprising:
 storing input/output limitation information for limiting display of display data received from the terminal device or limiting operation;   determining a state of a vehicle;   controlling to display a result of a process that the terminal device performed an application program when the state of the vehicle is a first state, and
 controlling to display an icon or a screen reduced in size of the application program being performed based on the input/output limitation information when the state of the vehicle is a second state different from the first state.
