Design and implementation of CAN bus protocol for monitoring vehicle parameters

Abstract

CAN bus is a serial bus protocol used in most automotive industries. Recently, more attention on the CAN bus network application and wireless transmission bus carrying technology. CAN bus technology is adopted in modern vehicles to reduce the wiring harness and controls the vehicle using electronics system. In this paper, CAN bus protocol is implemented using a single board computer (SBC) and accessed the vehicle parameters remotely. Raspberry Pi is used as SBC which has a high performance processor used to increase speed ability. The presented work concentrate on the communication between three nodes using a CAN bus and how to access modern vehicle ECU parameters using OBD II connector. The paper is described further set up of CAN device using Linux software.
