1. A method implemented by a first centralized controller, wherein the method comprises:
generating a resource access request when the first centralized controller accesses a first input/output (I/O) device of a plurality of I/O devices in a vehicle, wherein the resource access request comprises first standardized data for controlling a first standard model of a plurality of standard models of the I/O devices, and wherein when the first centralized controller needs to access a second I/O device of a second centralized controller, the resource access request further comprises a second standard model of the second I/O device;
converting, based on a mapping configuration file between the I/O devices and the standard models, the first standardized data into first control data corresponding to the first I/O device;
sending the first control data to the first I/O device;
sending the resource access request to the second I/O device through a communication- layer link between the first centralized controller and the second centralized controller, wherein the resource access request further comprises second standardized data for controlling the second standard model;
converting, based on the mapping configuration file, the second standardized data into second control data corresponding to the second I/O device; and
sending the second control data to the second I/O device through the communication-layer link between the first centralized controller and the second centralized controller.
