Towards a unified x-by-wire solution with HUMS, HM & TTP: Lessons learned in implementing it to a drive-by-wire vehicle

Abstract : Requirements for safer automotive control systems are ever-increasing, with issues such as safety-related systems, innovations, and cost reduction. Using Health and Usage Monitoring Systems (HUMS), Health Management (HM) techniques, and the Time Triggered Protocol (TTP), a Throttle-by-Wire (TbW) system was designed to gain experience in establishing a unified approach in integrating safety-related technologies. HUMS are used in aviation to reduce maintenance costs, and HM enables autonomous health management capability for vehicles. TTP is a safety-critical network, designed specifically to meet requirements for fault-tolerant systems. A TbW system replaces the mechanical connection in a vehicle, from the accelerator pedal to the engine throttle, with an electromechanical counterpart. This paper provides an insight in implementing these three technologies to a safety-critical system, and constructing such a system during the design and implementation phase.
