摘要

A model/sensor hybrid approach is implemented to conduct failure prognostics of an automotive electronic control unit (ECU). A 3-D finite-element model simulating a complex ECU is built, and its predictability is calibrated and verified by an optical displacement measurement technique called moiré interferometry. On the sensor front, a silicon-based piezoresistive stress sensor is embedded into th...
