A framework for health monitoring of automotive electrical and electronic control systems (poster)

Abstract

The automotive industry has seen enormous growth in the size and complexity of electrical and electronic system architectures. As complexity increases the problem of diagnosing faults in a vehicle's electrical and electronic systems is becoming increasingly difficult. Many faults are as a result of system-level disturbances or interactions that are difficult to interpret and diagnose using existing component-level diagnostics which have been traditionally focused on mechanical system diagnostics. The problem of rising complexity is exacerbated by increasing inservice warranty periods with some automotive OEMs now offering 5 or 7 year, or even 'life-time' warranties. This paper discusses the need for a new system-level approach to the management of faults in a vehicle's networked electronic systems and how this might be achieved by using the data that flows over a vehicle's data networks. This paper compares different industry approaches to system-level health monitoring of complex distributed computing environments and presents a proposal for the application of health monitoring to an automotive electrical and electronic architecture.

Prognostics and health monitoring of electronic system: A review

“…Amor-Segan et al [5] focuses on the automotive industry and proposes a new system level approach to manage the faults in a vehicle networked electronic systems. The framework involves different phases -data collection, data analysis, knowledge discovery, diagnostics or prognostics leading to corrective and preventative intervention.…”

“…Regardless of the fact that the clear indication of the system degradation is given by the physical parameters, these non-physical values can be used to link some physical parameters to the actual system performance. A framework is proposed in [5] regarding Electronic Control Unit (ECU) to use ECU hardware and software data to asses the health. It is using parameters from the ECU such as ECU reset and initialisation statistics, ECU error counts, function activation statistics, network status and performance statistics.…”

“…In Telecom, it is called Intelligent Platform Management Interface (IPMI), in aerospace, Integrated Vehicle Health Management (IVHM) [5], in electronics, Prognostics and Health Management [6]. In the maintenance perspective, it is Condition Monitoring (CM) [7].…”
