  • design of an automotive safety system using Controller Area Network
    International Conference on Robotics and Automation, 2015
    Co-Authors: K Kalaiyarasu, C Karthikeya
    Abstract:

    Most of the people are using vehicles which have become the most important part in our life for comfort transportation. In existing system the main snags are cost as well as the first one are glaring effect accidents due to opposite vehicle headlight illumination at night time driving. Second one is the short circuit fault in automotive wiring. Third one is to perceive the gas leakage fire accidents. And the fourth one is faults due to temperature of automotive engine location. The proposed system has two modules Master and Slave, they are communicating through Controller Area Network (CAN) protocol. The Master module has gas leakage detection with protection and temperature monitoring function. The Slave module has Automatic Front Headlight Adjustment system (AFHAS) and short circuit fault line indication function. The hardware has been developed in SMT (Surface Mount Technology) with SMD (Surface Mount Device) components and the hardware uses double layer PCB (Printed Circuit Board) design to optimize the space requirement and power consumption. The proposed system will be in cost effective safety system, reliability, and hardware will be small in size.

  • SOVCAN: Safety-Oriented Vehicular Controller Area Network
    IEEE Communications Magazine, 2017
    Co-Authors: Yin Zhang, Nachoua Guizani, Di Wu, Min Chen, Victor C. M. Leung
    Abstract:

    To meet the demands of vehicular Networks, such as high throughput, high mobility, low latency, heterogeneity, and scalability, SDN has been applied for raising the user experience through providing high-performance communications between vehicular Network nodes, reconstructing the vehicular Network structure, and optimizing Networking coverage, system security, communication latency, and so on. However, the existing SDN applications in the vehicular Network mainly focus on the data communications between the vehicles and other Network nodes or devices, while the vehicular Controller Area Network is still limited to some particular applications, only providing users with basic services, but unable to meet the demands in a complex driving environment. Thus, this article proposes an SDN-based approach to develop the safety-oriented vehicular Controller Area Network, which can guarantee traffic safety based on driver fatigue detection and emotional recognition, which are monitored through the driver's physiological and psychological state.

  • mixed criticality on Controller Area Network
    Euromicro Conference on Real-Time Systems, 2013
    Co-Authors: Ala Urns, Robe I Davis
    Abstract:

    An increasingly important trend in the design of real-time and embedded systems is the integration of components with different levels of criticality onto a common hardware platform. Where the platform incorporates a communication media it is necessary for that media to be able to safely and efficiently transfer messages of different criticality levels. In this paper we consider the Controller Area Network (CAN), and define mixed criticality protocols that could form the basis of a Trusted Network Component for CAN. Sufficient response-time analysis is derived for these protocols and an optimal priority assignment scheme is provided. Evaluations illustrate the benefits of the schemes.

  • robust priority assignment for messages on Controller Area Network can
    Real-time Systems, 2009
    Co-Authors: Robe I Davis, Ala Urns
    Abstract:

    This paper addresses the problem of determining the most robust priority assignment for CAN messages that are subject to transmission errors due to Electromagnetic Interference. In the presence of errors on the bus, CAN messages have a non-zero probability of missing their deadlines. An appropriate choice of priority ordering can minimise the overall worst-case deadline failure probability resulting in a more robust system. This paper shows that "deadline minus jitter" monotonic priority assignment, commonly used for priority assignment in commercial CAN systems, does not always result in the most robust priority ordering. A Robust Priority Assignment algorithm is presented that computes the most robust priority ordering for CAN messages subject to bit errors on the bus. This algorithm is optimal in the sense that it can be used to (i) maximise the number of errors tolerated, (ii) maximise the delay tolerated by any message, or (iii) minimise the probability of any message failing to meet its deadline. This algorithm is efficient and appropriate for use in an engineering context.

  • Controller Area Network can schedulability analysis for messages with arbitrary deadlines in fifo and work conserving queues
    International Workshop on Factory Communication Systems, 2012
    Co-Authors: Robe I Davis, Nicolas Nave
    Abstract:

    The majority of research into schedulability analysis for CAN is based on the assumption that the highest priority message ready for transmission at each node on the Network will be entered into arbitration on the bus. In practice; however, some CAN device drivers and communications stacks implement queuing policies that are not strictly priority-based, invalidating this assumption. In this paper, we introduce response time analysis for work conserving and FIFO queuing policies for messages with arbitrary deadlines.
