Rea1Time Fault Detection on In-Vehicle Power Line Networks Based on Power Line Communication

Real time detection of intermittent or permanent faults which could appear on wired networks becomes a critical issue. Fault detection and localization methods are often based on reflectometry techniques but they need the implementation of dedicated devices. Furthermore, since they often use a wide frequency band, problems related to their electromagnetic compatibility with the environment may occur. If a power line communication is already implemented in the network, the objective of this paper is to study the proof of concept of a fault detection only based on the statistical properties of the received signals. Even without precise information on fault location, results of this approach could be interesting to decide to carry out a maintenance operation.
