Abstract: Proposed are a device provided to a vehicle and a control method therefor. Specifically, proposed is a device provided to a vehicle, the device comprising: a plurality of system on chips (SoCs) which execute at least one application and are connected via a predetermined input/output interface; and a display which is provided in the vehicle and outputs an execution screen of the at least one application. Further, proposed is that a first SoC, among the plurality of SoCs, requests the execution of a specific application, among the at least one application, to a second SoC on the basis of the resource state of the first SoC, and as a response to the request, receives the execution result of the specific application from the second SoC.
