Design of Real-Time CAN Framework Based on Plug and Play Functionality

Abstract

Nowadays most vehicles are equipped with a variety of electronic devices to improve user convenience as well as its performance itself. In order to efficiently interconnect these devices with each other, Controller Area Network (CAN) is commonly used. However, the CAN requires reconfiguration of the entire network when a new device, which is capable of supporting both of transmission and reception of data, is added to the existing network. In addition, since CAN is based on the collision avoidance using address priority, it is difficult that a new node is assigned high priority and eventually it results in transmission delay of the entire network. Therefore, in this paper we propose a new system component, called CAN coordinator, and design a new CAN framework capable of supporting plug and play functionality. Through experiments, we also prove that the proposed framework can improve real-time ability based on plug and play functionality.

“…Kim and Hwang [10] suggest a new component for a controller area network (CAN), which has a number of advantages in supporting more accurate controls and in improving the performance and fuel efficiency of a vehicle by drastically reducing the number of wires in a vehicle. Their proposed component can manage the integrated information of each node in the same Bus.…”
