Abstract
A method to detect and mitigate sensor or actuator degradation in an automobile system includes: collecting a signal data output from at least one device which is outputting the signal data in response to monitored operational parameters of a motor vehicle system; analyzing patterns of the signal data compared to a signal data output from a nominal operating one of the at least one device using an artificial intelligence program; and identifying when the patterns of the signal data exceed a threshold level indicating the at least one sensor or actuator is operating in a degraded condition.
