Patent ID: 8560165

Claim:
A cooperative diagnostic system for generating a prognosis of at least one component in a vehicle, the system comprising: an in-vehicle diagnostic unit determining a degradation signature of the at least one component each time an occurrence of a condition is triggered; and an off-vehicle diagnostic unit receiving the degradation signature and determining a state-of-health of the at least one component as a function of the degradation signature; wherein the determined degradation signature of the at least one component is wirelessly transmitted to the off-vehicle diagnostic unit upon the occurrence of the triggered condition, the off-vehicle diagnostic unit determining a rate-of-change in the state-of-health of the at least one component, the off-vehicle diagnostic unit determining whether the rate-of-change in the state-of-health is greater than a threshold, the off-vehicle diagnostic unit requesting additional information from the vehicle in response to the rate-of-change in the state-of-health being greater than the threshold, the additional information relating to operating parameter data associated with the at least one component, the off-vehicle diagnostic unit receiving the requested information and predicting a time-to-failure of the at least one component.
