  • Power Line Communication in automotive harness on the example of local interconnect network
    2016 International Symposium on Power Line Communications and its Applications (ISPLC), 2016
    Co-Authors: Ghyoor Arshad Lodi, Andreas Ott, Sher Ali Cheema, Martin Haardt, Thomas Freitag
    Abstract:

    In recent years, the proliferation of electronic systems in modern cars has resulted in increased cost, complexity, and weight of the automotive wire harness. Moreover, the addition of nodes in to the existing wire harness, to provide additional functions, leads to an enormous routing effort. Power Line Communication (PLC) provides an attractive solution to these problems by providing an alternative medium of communication between the nodes through the vehicle's battery power line. In this work, a new transceiver architecture is proposed to provide PLC on the DC line in an automotive harness. The proposed scheme is based on the example of the local interconnect network (LIN) where only the physical layer is changed. Here, we propose to use redundant transmission channels, which are spaced in frequency, to provide robustness against the severe power line channel attenuation. An improvement in channel gain for the worst-case scenarios is demonstrated through a statistical evaluation of this scheme. The results show that an efficient use of the frequency spectrum enables the support of up to 15 LIN buses on a single power line, while ensuring 3-level redundancy. A system-level design of the PLC system for LIN and its specifications are presented. A further improvement in the system performance in the presence of impulsive noise is demonstrated by applying simple channel coding techniques.

  • A Stepwise Split Power-Driving Scheme With Automatic Slope Control for EMC-Enhanced LIN Transceiver
    IEEE Transactions on Vehicular Technology, 2018
    Co-Authors: Seungmok Kim, Daewung Kim, Kwangmuk Lee, Myunghee Lee, Jae Joon Kim
    Abstract:

    This paper proposes a split power-driving scheme for electromagnetic interference robust design and its automatic stepwise digital slope control for suppression of spectral emission. This analog–digital hybrid method gives power saving effect up to 24.4%, and also production reliability can be improved by utilizing a failure detection and recovery scheme. For feasibility of the proposed electromagnetic compatibility (EMC) scheme, a local interconnect network transceiver prototype is fabricated in a 0.18-μm BCD process, and experimentally verified to provide EMC-enhanced operation with low-cost and low-power overheads.

  • CICC - EMI resisting smart-power integrated LIN driver with reduced slope pumping
    2008 IEEE Custom Integrated Circuits Conference, 2008
    Co-Authors: Jean-michel Redoute, Michiel Steyaert
    Abstract:

    This paper presents the design of a local interconnect network (LIN) smart-power driver exhibiting a high degree of immunity against electromagnetic interference (EMI). Improving previous designed architectures, this circuit switches to a low power consumption mode when there is no EMI, while presenting an increased immunity to slope pumping. Measurements illustrate that this proposed LIN driver complies to the 5 W direct power injection (DPI) specification.

  • an emi resisting lin driver in 0 35 micron high voltage cmos
    European Solid-State Circuits Conference, 2007
    Co-Authors: Jean-michel Redoute, Michiel Steyaert
    Abstract:

    This paper describes the design of a local interconnect network (LIN) integrated output driver circuit exhibiting a high degree of immunity against conducted electromagnetic interference (EMI). The transmitted signal of this driver is shaped with a predefined slope so as to reduce electromagnetic emission at higher frequencies. The effect of EMI coupling from the data bus into the driver circuit is countered using a new feedback scheme which shields the slope shaping function from the output stage. Although the output signal may be heavily corrupted by EMI, the LIN driver continues to deliver an unaltered duty cycle, which is mandatory to obtain an error-free data transmission. Measurements show that this driver circuit manages to withstand the highest levels of the direct power injection (DPI) measurements independently of the injected EMI level.
