X-by-wire Technologies to Revolutionize Automotive Landscape, According to New ABI Study

    OYSTER BAY, N.Y.--Dec. 19, 2001--X-by-wire systems will gradually begin to replace nearly every mechanical linkage/cable and hydraulic line in a vehicle with electronic sensors and motors.
    A technology originally developed by the aerospace industry, x-by-wire is widely viewed as an opportunity to increase vehicle safety, performance, and fuel-efficiency, while also reducing design and manufacturing costs.
    According to a new study from Allied Business Intelligence Inc (ABI), "X-by-Wire: A Strategic Analysis of Time-Triggered Architectures and Next-Generation Automotive Control Systems," the global market for automotive x-by-wire systems will grow from approximately $600 million in 2001, to over $27 billion in 2010.
    "Automotive OEMs envision a day where autonomous vehicle control systems radically improve driver safety and convenience by not only assuming control of the vehicle in an emergency such as a skid, but as part of an automated highway system," according to Frank Viquez, senior analyst and report author. "X-by-wire is the critical component needed to realize that vision."
    Another key piece of the equation lies with the advent of 42-volt power systems, which will enable true x-by-wire (systems without a mechanical backup). Several European automakers, including Mercedes, BMW, PSA Peugeot-Citroen, and Renault have committed to launch 42-volt systems into their vehicle lines in 2004.
    To ensure reliability of these advanced systems, fault-tolerant, time-triggered communication protocols are compulsory. There are two protocols currently in development for automotive: the FlexRay protocol, (backed by BMW, DaimlerChrysler, GM, Motorola, Philips and Bosch); and TTP (time-triggered protocol), which is backed by Audi, PSA Peugeot-Citroen, Delphi, and Honeywell. However, if OEM suppliers need to support multiple protocols, the ultimate price will be higher development and product costs, resulting from smaller economies of scale in a polarized market.
    ABI estimates that by 2010, over 95% of the world's vehicles produced will have some version of an x-by-wire system installed, whether it be electromechanical braking, fully-electric steering, or electronic throttle control.
