Experimental Jitter Analysis in a FlexCAN Based Drive-by-Wire Automotive Application

In this paper, we describe several experiments designed to characterize jitter in an actual automotive application designed using FlexCAN, a CAN based communication architecture. Large and variable jitter has been a liability of the CAN protocol. The paper also explains how FlexCAN reduces jitter by using a simple message scheduling technique that synchronized with control system applications. Categories and Subject Descriptors C.2.4 [Distributed Systems]: Distributed applications. General Terms Measurement, Performance, Experimentation. Keywords CAN, FlexCAN, Jitter, Automotive, Drive-by-Wire.
