Abstract
An input/output (I/O) device access method includes a first centralized controller that performs object-oriented modeling on various I/O devices in a vehicle to generate standard models of the various I/O devices, and generate a mapping configuration file between the various I/O devices and the standard models. The first centralized controller further generates a resource access request based on an access operation of a user, where the resource access request includes a first standard model of a first I/O device accessed by the user. The first centralized controller further sends the resource access request to the first I/O device based on the mapping configuration file.
Claims20
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.
