Sample Point Position Measurement of Controller Area Network Nodes

摘要

In this paper a method for sample point position measurement in the bit interval of Controller Area Network (CAN) nodes is presented. The position of sample point is an important parameter of CAN network node configuration, as it particularly influences the bit error rate and consequently frame error rate within the whole system. The measurement method, implementation of a specialized test instrument and the measured results evaluation are described, as well as validation procedure of the described method and its results.
