Patent ID: 7899591

Claim:
An energy efficiency determination system comprising: a receiver that receives operational data about an asset from a sensor indicative of at least one operational characteristic; a memory that stores the operational data; an asset efficiency model indicative of energy efficiency of the asset; a processor in communication with the asset efficiency model and the memory, the processor analyzing real-time energy efficiency of the asset based on the operational data and the asset efficiency model, assessing whether to perform maintenance on the asset based at least on improved efficiency of the asset due to the performed maintenance, and scheduling the maintenance based on the assessing whether to perform the maintenance, wherein the asset comprises a vehicle; wherein the asset efficiency model comprises data indicative of optimal efficiency of the vehicle, further wherein assessing whether to perform maintenance on the asset based at least on improved efficiency of the asset due to the performed maintenance comprises: determining a first cost of an increased fuel consumption until a next scheduled vehicle maintenance event; determining a second cost of performing maintenance on the asset; and comparing the first cost impact with the second cost impact.
