A generic test platform representing networked embedded systems in vehicles
ABSTRACT In order to verify the effectiveness of the system-level fault diagnostic method which has been designed for the self-healing vehicle (SHV) concept, this paper has developed a generic test platform (GTP) on which to implement the designed diagnostic method. The platform represents the distributed and networked electronic control system of a real vehicle. The more important is that in this platform the functions of an individual network node and the whole networked system are able to be configured to operate in different scenarios. This enables the platform to mimic a real vehicle system in the presence of faults which is indispensable for the validation of a diagnostic method.
Conference Proceeding: Hardware in the loop simulation of embedded automotive control system[show abstract] [hide abstract]
ABSTRACT: Distributed embedded control systems play an increasing role in modern automotive designs and there is a pressing need to investigate the impact of different design decisions on system safety and reliability. A highly effective method of performing the testing for such an investigation is via a suitably detailed "hardware-in-the-loop" (HIL) simulation. This paper describes a novel HIL testbed that has been developed for this purpose in the Embedded Systems Laboratory at the University of Leicester. An overview of the simulator is provided, followed by detailed descriptions of the vehicle and driver models that are employed. The performance of the system is illustrated using an example based on an adaptive cruise control system.Intelligent Transportation Systems, 2005. Proceedings. 2005 IEEE; 10/2005
Conference Proceeding: Adaptive OSEK Network Management for in-vehicle network fault detection[show abstract] [hide abstract]
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.Vehicular Electronics and Safety, 2007. ICVES.

Conference Proceeding: Towards the Self Healing Vehicle[show abstract] [hide abstract]
ABSTRACT: This paper addresses the question of how an intelligent vehicle could play a more proactive role in fault management. In particular, it describes the concept of the Self Healing Vehicle: a vehicle with the ability to autonomously predict or detect and diagnose failure conditions, confirm any given diagnosis, and perform appropriate corrective intervention(s), including the use of telematics to interact with external service providers and infrastructures. The key research questions that need to be answered in order for a self healing vehicle to be realised are explored, and a framework for how this concept might be realised is presented.Automotive Electronics, 2007 3rd Institution of Engineering and Technology Conference on; 07/2007
