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.
