METHOD AND APPARATUS FOR ACCESSING I/O-DEVICES

Embodiments of this application disclose an I/O device access method and apparatus. The method includes: A first centralized controller 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 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 sends the resource access request to the first I/O device based on the mapping configuration file. According to the embodiments of this application, flexibility and reliability of accessing different types of I/O devices by a centralized controller can be improved.
