Abstract

A system includes a vehicle control module, an operating information module, and a fuel analysis module. The vehicle control module is configured to obtain a trip plan for the vehicle. The operating information module is configured to be disposed on-board the vehicle and to autonomously obtain operating information describing one or more of tractive events or braking events performed during the trip. The fuel analysis module is configured to be disposed on-board the vehicle, to receive the operating information from the operating information module, and to autonomously determine a fuel consumption for at least a portion of the trip using the operating information received from the operating information module.
