Abstract
A sensor failure accommodation system includes a control computer receiving a sensor signal corresponding to an engine operating condition, and estimating a value of the engine operating condition as a function of one or more engine operating parameters different than the engine operating condition. The computer is operable to control one or more air handling mechanisms as a function of a final engine operating condition value, and if the sensor producing the engine operating condition signal is error free the final engine operating condition value is the engine operating condition signal. If the sensor producing the engine operating condition signal has failed, the final engine operating condition value is the engine operating condition estimate, and if at least one sensor producing the one or more engine operating parameters has also failed, the final engine operating condition value is a commanded or other definable engine operating condition value.
