A method is presented that converts field life temperature data collected underhood during actual driving conditions into a segmented temperature cycling life cycle profile using rainflow counting techniques. This profile can then be used as the true field condition in performing Physics of Failure based virtual qualification or accelerated testing of an automotive engine control unit operating in an elevated temperature environment. The specific elements of this method and its validation on an engine control unit will be presented.
