Adaptive OSEK Network Management for in-vehicle network fault detection

Abstract

Rapid growth in the deployment of networked electronic control units (ECUs) and enhanced software features within automotive vehicles has occurred over the past two decades. This inevitably results in difficulties and complexity in in-vehicle network fault diagnostics. To overcome these problems, a framework for on-board in-vehicle network diagnostics has been proposed and its concept has previously been demonstrated through experiments. This paper presents a further implementation of network fault detection within the framework. Adaptive OSEK Network Management, a new technique for detecting network level faults, is presented. It is demonstrated in this paper that this technique provides more accurate fault detection and the capability to cover more fault scenarios.
