VEHICLE CONSUMPTION MONITORING SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vehicle consumption monitoring system and method.SOLUTION: A monitoring system 102 and method determine a consumption metric representative of one or more of an amount of fuel consumed or an amount of energy consumed by a vehicle 100 during travel over a route. The consumption metric is independent of one or more of a vehicle load and an elevation change over the route. The system and method optionally can determine a route condition metric representative of a condition of a route traveled upon by a vehicle. The route condition metric is based on a comparison between an actual grade of the route at one or more locations along the route and an estimated grade of the route at the one or more locations.SELECTED DRAWING: Figure 1
