Abstract

Claims (51)

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.

2. The method of claim 1 , wherein the mapping configuration file comprises a conversion relationship between standardized data that controls the standard models and control data that controls the I/O devices.

3. The method of claim 1 , further comprising:

receiving sampled data from the first I/O device; and

converting, based on the mapping configuration file, the sampled data into second standardized data corresponding to the first standard model.

4. The method of claim 1 , further comprising performing object- oriented modeling on the I/O devices to generate the standard models.

5. The method of claim 1 , further comprising implementing, by configuration, the mapping configuration file.

6. The method of claim 1 , wherein the first I/O device belongs to the first centralized controller.

7. A first centralized controller for controlling access to a plurality of input/output (I/O) devices in a vehicle, wherein the first centralized controller comprises:

convert, based on the mapping configuration file, the first standardized data into first control data corresponding to the first I/O device; and

one or more transceivers coupled to the one or more processors and configured to:

send the first control data to the first I/O device based on the mapping configuration file; and
